Answer:
You might think the answers to the questions “what is a library?” and “what is the Internet?” are pretty obvious. But actually, it is easy to get them confused, and there are a number of research resources that are a bit of both: library materials available over the Internet or Internet resources available in the library.
Understanding the differences between the library and the Internet and knowing where your research comes from is crucial in the process of research writing because research that is available from libraries (either in print of electronic form) is generally considered more reliable and credible than research available only over the Internet. Most of the publications in libraries (particularly in academic libraries) have gone through some sort of review process. They have been read and examined by editors, other writers, critics, experts in the field, and librarians.
In contrast, anyone with appropriate access to the Internet can put up a Web page about almost anything without anyone else being involved in the process: no editors, other writers, critics, experts, or anyone else review the credibility or reliability of the evidence.
However, the line between what counts as library research and what counts as Internet research is becoming blurred. Plenty of reliable and credible Internet-based research resources are available: online academic and popular journals, Web-based versions of online newspapers, the homepages of experts in a particular field, and so forth.
Let’s begin with the basics of understanding the differences between libraries and the Internet.
Libraries are buildings that house and catalog books, magazines, journals, microfilm, maps, government documents, and other resources. It would be surprising if you attended a community college, college, or university that did not have a library, and it would be equally surprising if your school’s library wasn’t a prominent and important building on campus.
As you might expect, libraries at community colleges, colleges, and universities tend to specialize in scholarly materials, while public libraries tend to specialize in non-scholarly materials. You are more likely to find People magazine or the latest best-selling novels in a public library and a journal like College English and scholarly books in a college library.
Many universities have different libraries based on distinctions like who tends to use them (“graduate” or “undergraduate” libraries) or based on specific subject matter collected within that particular library (education, social work, law, or medicine). Almost all college and university libraries also have collections of “special items,” which include items like rare books, maps, and government documents.
Almost all universities, colleges, and community colleges in the United States provide students and faculty with access to the Internet so they can use email and the World Wide Web, or even so they can publish Web pages. Millions of people both in and out of school have access to the Internet through “Internet Service Providers,” which are companies both large and small that provide customers access to the ‘net for a monthly fee.
Quadrupedal monkeys __________ Group of answer choices have long arched spines for flexible movement when leaping. hold their bodies parallel to the ground (pronograde posture) when walking have narrow rib cages with scapula on the side, limiting the range of motion in the shoulder All of these traits characterize quadrupedal monkeys
Answer:
All of these traits characterize quadrupedal monkeys
Explanation:
Quadrupedal monkeys have long arched spines that is used for flexible movement when jumping to a height. They hold their bodies parallel to the ground because of pronograde nature means these monkeys walking with the body by using four legs. While walking they have narrow rib cages with scapula on the side that limits the range of motion in the shoulder.
Why do you think type 2 diabetes occurs so much more often than other inheritable diseases? Propose a hypothesis for why this allele has not been eliminated by natural selection.
Which type of species best describes a mouse: opportunistic or equilibrium? Explain why a mouse or rat population would continuously grow while other mammals (cheetahs) are nearly extinct.
Answer:
This allele has not been eliminated by natural selection because it may confer an adaptive advantage for particular environmental conditions
Mice and rats are opportunistic species. These species can rapidly adapt to different environmental conditions, while cheetahs are unable to adapt to changing environments.
Explanation:
An allele is a gene variant that may be beneficial, neutral, or deleterious for a particular environment. Different alleles are not eliminated by natural selection against other alleles (even when a priori seem to be deleterious) because they confer a selective advantage in a given environment. For example, the allele for sickle cell anemia is caused by a point mutation which is lethal in homo-zygous individuals, but heterozygous individuals are less likely to die of malaria, thereby this allele has been positively selected in geographic areas where malaria is an endemic disease. Moreover, mice and rats are opportunistic species, i.e., they are species that rapidly adapt to varied living conditions. These species are characterized to have high growth rates and produce many offspring. On the other hand, the cheetah is a highly specialized species that is unable to adapt to changing environments. In consequence, cheetah populations are more prone to become extinct than rat and mice populations.
What is the answer with explaining
Answer:
EeWw
Explanation:
The allele for the earlobe is depicted as e while that of the hairline is w.
A parent that is homzygous recessive for earlobes (ee) and homzygous dominant for hairline (WW) would have the genotype eeWW.
The other parent that is homzygous dominant for unattached earlobes and homzygous recessive for hairline would have the genotype EEww
eeWW x EEww
During meiosis, each genotype will form gametes.
eeWW: eW, eW, eW, eW
EEww: Ew, Ew, Ew, Ew
These gametes will randomly unite during fertilization to produce offspring. Since the same gametes are formed by each parent:
eW x Ew
offspring
100% EeWw (see the attached image for the Punnet's square)
The genotype of all the children would be EeWw and would phenotypically be with unattached earlobes and dominant hairline.
How are inherited characteristics passed on through generations?
Inherited characteristics are passed on through generations via the transfer of genetic information from parents to offspring. This genetic information is encoded in DNA, organized into genes, and carried on chromosomes.
How are inherited characteristics passed on through generations?Inherited characteristics are passed on through generations via the transmission of genetic information from parents to offspring. This genetic information is contained within molecules called DNA (deoxyribonucleic acid), which is located in the cells of organisms. The process of passing on inherited characteristics is known as heredity, and it occurs through the following mechanisms:
Genes and Alleles: Genes are segments of DNA that code for specific traits or characteristics. Each gene has different forms called alleles. These alleles can vary and determine the variations in traits among individuals.
Chromosomes: DNA is organized into structures called chromosomes. Humans have pairs of chromosomes, with one member of each pair coming from each parent. Each chromosome contains numerous genes.
Gamete Formation: In sexual reproduction, special cells called gametes (sperm and egg cells) are formed through a process called meiosis. During meiosis, the genetic material is shuffled and divided, creating gametes with a unique combination of genetic information.
Fertilization: When two gametes (sperm and egg) fuse during fertilization, they combine their genetic material, resulting in a new individual with a mix of genetic traits from both parents.
Dominant and Recessive Traits: Some traits are governed by dominant and recessive alleles. Dominant alleles mask the presence of recessive alleles. The combination of alleles determines the expression of traits in offspring.
Mendelian Inheritance: The principles of inheritance were first described by Gregor Mendel, and they involve the segregation and independent assortment of alleles during gamete formation and fertilization.
Genetic Variation: Sexual reproduction and the shuffling of genetic material during meiosis create genetic variation among offspring. This variation is essential for populations to adapt to changing environments over time.

What is Endoplasmic Reticulum? -,-
Answer:
It is a transportation system.
Explanation:
The endoplasmic reticulum is considered as the transportation system of the eukaryotic cell, and perform many important functions such as protein folding. Endoplasmic reticulum is a type of organelle which is made up of two subunits i.e. rough endoplasmic reticulum, and smooth endoplasmic reticulum. Endoplasmic reticulum performs a variety of essential cellular functions such as protein synthesis, processing, lipid synthesis, and calcium storage and its release in the body.
Answer:
So, the mitochondria are like the cell's power plant and the nucleus are the command center, then the endoplasmic reticulum (ER) is the cell's factory. This type of organelle is a packaging and storage facility. The ER is separated into two types – rough and smooth.
The rough ER looks like sheets of bumpy membrane. The bumps are just ribosomes attached to the organelle. The function of the rough ER is protein synthesis, (it's where the proteins are made). Ribosomes create amino acids that are built into proteins inside the ER. Some of the proteins are used by the cell, while others are packaged and sent out through the cell membrane for use elsewhere.
The smooth ER is a network of tubes attached to the rough ER. It is called smooth ER because it lacks ribosomes. The smooth ER is responsible for the production and storage of steroids and lipids, also known as fats. It also stores calcium ions used by muscle tissue.

Answer:
A.
Explanation:
Mutations that happen in sex cells during meiosis are able to pass onto offspring.
"Mutations in sex cells can be passed on to children." Therefore, option (A) is correct.
What is mutation?A mutation in a sex cell differs from a mutation in a non-sex cell in that mutations in sex cells can be passed on to children. Sex cells, such as eggs and sperm, carry genetic information that is passed on to the next generation during fertilization.
If a mutation occurs in a sex cell, it can be transmitted to the offspring and can potentially affect the genetic makeup of future generations. On the other hand, mutations in non-sex cells, such as skin cells or liver cells, cannot be passed on to offspring because they do not contribute to the genetic material of the next generation.

Answer:
pancreatic juice
Explanation:
The pancreas secretes the pancreatic juice, composed of enzymes, water, bicarbonate, and electrolytes produced by acinar and epithelial cells. Secretory pancreatic cells are organized in sac-shape structures called acini. These structures are conformed of acinous cells and center-acinous cells that secrete digestive enzymes into the intestine The pancreatic juice flows along the principal pancreatic duct to the bile duct and from there to the small intestine. In the intestine, it degrades fats, carbohydrates, and proteins.
Your friend works in a lab that examines microtubules. She decides to grow some microtubules in vitro. After growing some with normal (Alpha-Beta)‐tubulin dimers bound to GTP, she replaces them with only GMPCPP bound (Alpha-Beta)‐tubulin dimers. GMPCPP is analog of GTP that cannot be hydrolyzed to GDP
Will she observe dynamic instability in her GMPCPP‐bound microtubules? Explain.
Answer:
No, she will not observe dynamic instability
Explanation:
Microtubules are dynamic polymers formed by the assembly of α‐ and β‐tubulin, which alternate between growing and shrinking states. These states are regulated by the hydrolysis of GTP bound to β-tubulin. In consequence, the dynamic behavior of the microtubules depends on the binding and hydrolysis of GTP by β-tubulin, which alters the conformation of tubulin molecules. The Guanylyl 5′-α,β-methylenediphosphonate (GMPCPP) is a slowly hydrolyzing analog of GTP that binds to tubulin with an affinity four to eightfold lower than GTP, which is used to produce stable microtubules that resist their depolymerization. When microtubules are polymerized with GMPCPP, they do not undergo dynamic instability, because GTP hydrolysis is necessary for their switching behavior.

b. Often the initial stage in the evolution of a complex character was an adaptation to some unrelated selection pressure.
c. Usually a single mutation in one gene leads to the simultaneous appearance of the complex character.

e. Usually a single mutation in one gene leads to the simultaneous appearance of the complex character.
Answer:
b. Often the initial stage in the evolution of a complex character was an adaptation to some unrelated selection pressure.
d. Phylogenetic analysis using cladistics can help reveal the sequence leading to the evolution of a complex character.
Explanation:
The evolutionary developmental program of complex characters can be analyzed by examining synapomorphies, i.e., by examining shared, derived characters common between an ancestor of a given taxonomic group and its descendants. Synapomorphies are able to create evidence for historical relationships between closely related organisms. Moreover, cladistics is a method used to categorize species/taxa into groups called 'clades' based on arranging organisms with similar traits, which can provide useful information on the evolutionary history of complex traits in different species/taxa. In phylogenetics, the analysis of complex characters involves two different stages: 1-character analysis and 2-cladistic analysis. Homology refers to structures that look similar because they were inherited from a common ancestor (i.e., they have a common origin); whereas characters are considered as parts of transformation series. In cladistics, characters used for inferring phylogenetic relationships are considered as hypotheses of homology that are subject to tests of similarity. In consequence, such characters can provide useful information on the evolutionary history of complex traits.
