What is the relationship between DNA mutation and sickle-cell anemia? (1 point)
O Sickle-cell anemia and DNA mutations are correlated without any causal relationship.
O Sickle-cell anemia causes a DNA mutation.
O A DNA mutation causes sickle-cell anemia.
O A DNA mutation is correlated with but does not cause sickle-cell anemia.
Answer:
A DNA mutation causes sickle-cell anemia.
Explanation:
Sickle cell anemia is caused by a single code letter change in the DNA. This in turn alters one of the amino acids in the hemoglobin protein. Valine sits in the position where glutamic acid should be. The valine makes the hemoglobin molecules stick together, forming long fibers that distort the shape of the red blood cells, and this brings on an attack.

HEEELLLPPP PLSS!!! Compare and contrast open, closed, and isolated systems. Be sure to discuss the exchange of energy and exchange of matter, and provide at least one example of each.
Answer:
See the answer below
Explanation:
An open system is a type of thermodynamic system in which energy and matter are being exchanged between the system and the surrounding. It is like boiling soup in an open pot. The opening allows for the addition of materials (matters) into the soup and energy is exchanged through the heating. A good example is found in biological organisms. They consume matters and exchange energy with the environment by carrying out work.
A closed system is a type of system in which there is no exchange of matter between it and the environment. However, there is an exchange of energy. It is like boiling water in a closed pot. Nothing can be added into the pot due to the closure but energy can be transferred through the heating of the pot.
An isolated system allows for neither energy nor matter exchange with the surrounding. It is like a closed food warmer that allows for nothing to enter or leaves it.
Answer: Open systems are energy that can be transferred between the system and its surroundings. Close systems are systems that do not transferred to its surroundings. Isolated systems is a thermodynamic system which cannot exchange either energy or matter from outside its boundaries of the system.

corrugated cardboard tube - digestive tract
irregular surfaces on the corrugated tube - villi
pump - heart
Plastic tubing - blood vessels
Explanation:
The corrugated cardboard tube represents the digestive tract. The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.
Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.
The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.
The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body

b. Glucose 6-phosphatase gluconeogenesis
c. Hexokinase glycolysis & gluconeogenesis
d. Fructose I ,6-bisphosphatase gluconeogenesis
e. Phosphofructokinase glycolysis
f. Pyruvate kinase glycolysis
Explanation:
Triose phosphate isomerase is a protein that functions as an enzyme, and takes part in glycolysis, in the interconversion of dihydroxyacetone phosphate and D-glyceraldehyde 3-phosphate. Glucose 6-phosphatase is also a protein that works as an enzyme, it hydrolyzes glucose 6-phosphate given glucose free as a result. Hexokinase is a protein too, and is part of a wider group of enzymes. It forms hexose phosphate by phosphorylating hexoses (six-carbon sugars). Fructose I ,6-bisphosphatase is an enzyme too, and it tranforms fructose-1,6-bisphosphate into fructose 6-phosphate. Phosphofructokinase is an enzyme too, that works in changing a phosphoryl group from ATP to fructose-6-phosphate (F6P). Pyruvate kinase is an enzyme that catalyzes the conversion of ADP tp ATP and phosphoenolpyruvate to pyruvate.

The original name for Asian Homo erectus was Group of answer choices Homo rudolfensis. Australopithecus. Paranthropus. Pithecanthropus.
Answer: Pithecanthropus erectus.
Explanation:
Between 1891 and 1892 Eugène Dubois believed he had found the "missing link", hypothesized by Ernst Haeckel, when he discovered some loose teeth, a skull cap and a femur - very similar to that of modern man - in the excavations he was carrying out in Trinil, located on the island of Java, Indonesia. Homo erectus erectus was the first specimen of Homo erectus to be discovered. Dubois first named it Anthropopithecus erectus and then renamed it Pithecanthropus erectus. The name Homo erectus means in Latin "erect man", wich means, "standing man", whereas Pithecantropus erectus means "standing ape-man".
So, Dubois published these findings as Pithecanthropus erectus in 1894, more popularly known as "Java Man" or "Trinil Man". In the 1930s the German palaeontologist Ralpf von Koenigswald obtained new fossils, both from Trinil and from new locations such as Sangiran and in 1938 von Koenigswald identified a magnificent Sangiran skull as "Pithecanthropus". It was not until 1940 that Mayr attributed all these remains to the genus Homo (Homo erectus erectus).

In meiosis, each centromere has a spindle fiber attached only to one side. In mitosis, each centromere has a spindle attached to how many sides?
Answer:
In mitosis, each centromere has a spindle attached on both side of centromere
Explanation:
In mitosis, each centromere has a spindle attached on both side of centromere because Spindle fibers move chromosomes during cell division by attaching to chromosome arms and centromeres. A centromere is the specific region of a chromosome where replicates are linked together.
Spindle fibers are active in mitosis and also meiosis and they move throughout the cells and also direct chromosomes to move to where they need to move to.
Spindle fibers function in centromere in mitosis and meiosis by pulling homologous chromosomes apart after they might have been replicated to prepare for division.

att
uaa
taa
uua
Answer:
uaa
Explanation:
An anticodon is a trinucleotide sequence localized in the transport RNA (tRNA) that binds via complementary base pairing to the codon in the messenger RNA (mRNA) during protein synthesis (translation). Thus, the tRNA anticodon binds with its complementary three-letter mRNA codon during translation in order to add a specific amino acid to the growing protein. Generally, the anticodon sequence positions 34–36-nt of the tRNA that reads its cognate mRNA codon sequence via Watson–Crick base pairing.
What growth information leads to your answer? The colonies are able to grow on minimal medium containing no additional supplements. The colonies are able to grow on complete medium.
Answer:
A growth medium or culture medium is a solid, liquid or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation,[1] or small plants like the moss Physcomitrella patens.[2] Different types of media are used for growing different types of cells.[3]
The two major types of growth media are those used for cell culture, which use specific cell types derived from plants or animals, and microbiological culture, which are used for growing microorganisms, such as bacteria or fungi. The most common growth media for microorganisms are nutrient broths and agar plates; specialized media are sometimes required for microorganism and cell culture growth.[1] Some organisms, termed fastidious organisms, require specialized environments due to complex nutritional requirements. Viruses, for example, are obligate intracellular parasites and require a growth medium containing living cells.

atch the term with the correct cellular process or definition. - A molecule containing genetic information - RNA base that pairs with adenine - Carries amino acid to ribosomes - The site of protein synthesis - DNA base that pairs with adenine - Carries the genetic code to ribosomes A. mRNA B. DNA C. tRNA D. Thymine E. Uracil F. rRNA G. Ribosome
Answer:
A molecule containing genetic information - DNA
RNA base that pairs with adenine - Uracil
Carries amino acid to ribosomes - tRNA
The site of protein synthesis - Ribosome
DNA base that pairs with adenine - Thymine
Carries the genetic code to ribosomes - mRNA
Explanation:
DNA is the molecule that is responsible for conveying genetic information in living organisms. It is made up of deoxyribose sugar, a phosphate group, and purine/pyrimidine bases. The purine bases consist of adenine and guanine while the pyrimidine bases include thymine and cytosine. As a matter of rule in the DNA, Adenine base always pairs with Thymine base while the Cytosine base always pairs with Guanine base.
RNA on the other hand is single-stranded unlike the double strands of DNA. It has all the nucleotide bases present in DNA except that the Thymine bases are usually replaced with Uracil.
There are three types of RNA:
the messenger RNA that is responsible for carrying genetic code from DNA to the ribosome for translation purpose, the transfer RNA responsible for carrying amino acids to ribosome during the translation process; and the ribosomal RNA which forms an integral part of the subunits of the ribosome itself.QUICKLY! The chemical reaction equation of photosyntesis is shown here: What information is not given in this equation. It does not show if the reaction is reversible. It does not show the reactants needed for the reaction. It does not show that photosynthesis consists of many separate steps. It does not show the number of molecules required to produce glucose.
Answer:
C: It does not show that photosynthesis consists of many separate steps.
Explanation:
Photosynthesis is a unique process carried out by the cells of autotrophic organisms. It is the process whereby they synthesize their own food in form of sugars (glucose) in the presence of sunlight. Ideally, the photosynthetic process makes use of carbon dioxide (C02) and water (H20) in the presence of light energy (from sun) to produce glucose sugar (C6H12O6) and oxygen (02). The general photosynthetic equation is as follows:
6CO2 + 6H20 + light → C6H12O6 + 6O2
However, the process is not as simple as portrayed as it involves many separate steps that collectively forms the photosynthetic product (glucose). Photosynthesis occurs in two major stages namely: light stage and light independent stage, which in turn consists of series of reactions that forms the products.
Therefore, the equation attached to this question describes photosynthesis but It does not show that photosynthesis consists of many separate steps.
Answer:
C: It does not show that photosynthesis consists of many separate steps.

Intrinsic factor A. increases gastric motility. B. causes the release of stomach acid. C. facilitates the absorption of vitamin B12. D. protects the stomach lining from the effects of stomach acid. E. stimulates the synthesis of DNA.
Answer:
C. facilitates the absorption of vitamin B12.
Explanation:
The Intrinsic factor is a substance that is produced by the stomach and it has the important function of producing vitamin B12 which is necessary for life. Vitamin B12 is used in the production of mature red blood cells. It also improves the function of the nervous system. The production of this intrinsic factor is a very vital role of the stomach because, in the absence of a stomach, for example, in the case of a gastrectomy, a person can only survive if he is given injections of Vitamin B12.
The stomach also serves as a holding center for food and eventually delivers the food to the small intestine and the duodenum.

Describe Dr. Vellend's unifying theory of ecological communities (the factors that determine community structure). Where do concepts like competition, predation, habitat suitability, disease and parasitism, and disturbance (most of what we covered this semester) fit into his theory
Answer and Explanation:
Community ecology is a discipline that studies the organism's communities and the manner in which populations of species interact with each other within a particular habitat. Mark Vellend is an eco-evolutionist that developed a theoretical framework of ecological communities from a unified functional perspective. This theory is based on four forces of evolutionary biology: selection, drift, dispersal and speciation. This theory is used to explain how species interactions including parasitism, competition and predation may influence population fluctuations. On the other hand, this theoretical framework can also be used to understand how colonization, disturbance and habitat suitability components alter the dynamics of interacting species.
