Answer:
Provide an enormous surface area that facilitates absorption.
Explanation:
The villi of the small intestine provides an enormous surface area that facilitates absorption of nutrients from the small intestine. The cells present on the villi are packed full of tiny hair-like structures called microvilli. It performs the same function as villi perform in the small intestine i.e. absorb nutrients. Villi are surrounded with cells that help in the absorption of nutrients from the food that passes through it.
‼️Need answer asap‼️. Which jar contains a mixture? A jar of solid carbon. A jar of carbon dioxide gas. A jar of liquid copper. A jar of copper and water.
Answer:
A jar of copper and water
Explanation:
The rest are compounds.
An experiment was conducted to determine whether a deficiency of carbon dioxide in the soil affects the phenotype of peas. Listed below are the phenotype codes where 1=smooth-yellow, 2=smooth-green, 3=wrinkled-yellow, and 4=wrinkled-green. Do the results make sense?
Answer:
No
Explanation:
The results of the phenotype do not make any sense in relation to the main aim of the experiment.
Smooth, wrinkled, yellow, green describe attributes relating to seed texture and flower colours in a result that simulates that of a plant breeding experiment, rather than a plant physiology experiment.
The determination of the effects of carbon dioxide deficiency in the soil on the phenotypes of peas is a physiological experiment. Hence, a result in the form of a plant breeding experiment would make not be relevant.
Eukaryotic chromosomes contain two general domains that relate to the degree of chromatin condensation. These two regions are _
Answer:
This question lacks options, options are: A) Heterochromatin and euchromatin
B) Uniform in the genetic information they contain
C) Separated by large sketches of repetitive DNA
D) Each void of typical protein-coding sequences of DNA
E) Void of introns.
The correct answer is A.
Explanation:
The chromatin or substance that makes up the nuclei of cells and that results from the interaction of DNA with histonic and non-histonic proteins and RNA; it can present different degrees of packing or contraction. When chromosomes are stained with chemicals that bind to DNA, densely stained regions and less densely stained regions appear. Heterochromatin are segments of the chromosome that stain strongly and remain visible, practically, during the entire cell cycle. There are few genes in these regions and therefore low transcriptional activity. They are supercondensed regions. Euchromatin are segments of the chromosome that are not visible during telophase and interphase, only in metaphase. It corresponds to regions that are less compact and in which there is a higher gene density.

Immediately following the arrival of the stimulus at the axon terminal there is a short period called the ________ period during which no muscle tension is observed while the neurotransmitter is being released by exocytosis, diffusing across the synaptic cleft, and binding to its receptor to activate the muscle cell. relaxation latent contraction refractory
Answer:
Immediately following the arrival of the stimulus at the axon terminal there is a short period called the latent period.
Explanation:
When a stimulus reaches the terminal of an axon, a period known as the latent period begins. This period has a short duration and during it it is possible to observe the blockage of new stimuli in the nerve fiber. Thus, the new stimuli fail to trigger an impulse and no muscle tension to be observed.
While the latent period is not finished, the neurotransmitter is released through the action of exocytosis that moves until it gets access to the receptor capable of activating the muscle cell.

Species that compete for the same resources often switch to either use different resources or find ways to reduce competition. Why is this often true
Answer:
The correct answer is - to increase their survivability and reproductivity in the species.
Explanation:
Competition is the result of an interaction between two or more species or populations where both need or depends on the same limited resources that is utilized and protected by both and due to this one individual reduces the survival or reproduction of another individual.
In order to survive and reproduce their numbers species have to find other resources to feed or utilize or have to find new ways as if they did not adapt as per the changes they will be left very few or extinct.

In a population of mole-rats, some have a little larger teeth and longer claws. If those particular mole-rats survive because they can dig quicker and the others are preyed on and do not survive to reproduce, what will eventually happen in subsequent generations?
Answer:
One increase in population and the other decrease.
Explanation:
The population of the rats having little larger teeth and longer claws increases as compared to those rats having small teeth and shorter claws because the rats can escape from their predators and survive in that environmental conditions. The population of rats having small teeth and shorter claws extinct in the end due to no reproduction and preyed by the predators and dominated by the population of the rats having little larger teeth and longer claws due to their features.

When Linnaeus began classifying organisms in the 1700s, he categorized them as plant, animal, or mineral. These kingdoms were later revised to exclude minerals and expanded to include animals, plants, fungi, protists, and bacteria. Which of the following best explains a reason for this change? (2 points)
Group of answer choices
As new organisms were discovered, new kingdoms were created to sort them based on ability to interbreed.
It was discovered that the organisms in each of the five kingdoms have a different method of obtaining nutrients and are therefore fundamentally different.
Technological advances led to the discovery of single-celled organisms and increased our understanding of relationships between organisms.
Genetic research led to the discovery that each of these five kingdoms has a unique evolutionary ancestor.
Answer:
It was discovered that the organisms in each of the five kingdoms have a different method of obtaining nutrients and are therefore fundamentally different.
Explanation:
New kingdoms were needed that reflected our growing knowledge of the differences between living organisms.
Protein digestion begins in the ________; fat digestion begins in the ________. Stomach; small intestine Mouth; stomach Esophagus; stomach Small intestine; small intestine Small intestine; large intestine
Answer:
Protein digestion begins in the mouth
Fat digestion begins in the stomach
Once a protein supply reaches your stomach, hydrochloric acid and enzymes referred to as proteases spoil it down into smaller chains of amino acids. Amino acids are joined collectively through peptides, that are damaged through proteases.
Fat digestion starts offevolved withinside the stomach. Some of the byproducts of fats digestion may be immediately absorbed withinside the stomach. When the fats enters the small intestine, the gallbladder and pancreas secrete materials to in addition spoil down the fats.
What is digestion?The approaches of digestion encompass six activities: ingestion, propulsion, mechanical or bodily digestion, chemical digestion, absorption, and defecation. The first of those approaches, ingestion, refers back to the access of meals into the alimentary canal thru the mouth.
Thus it is well explained.

When calcium levels in the blood are too low, the body releases a hormone that removes calcium from the bones. A person who suffers from a certain type of thyroid disease will often have low blood calcium and brittle bones because the body is taking the calcium from the bones. The afflicted person will typically see an endocrinologist, who studies hormones, and an orthopedist, who studies bones. What do these two doctors have in common
Answer:
They both would need to check the calcium levels
Explanation:
The two doctors would both need to check the calcium levels of the patient.
While the endocrinologist would need to check the calcium level in the blood, the orthopedist would have to check the calcium level in the bones of the patient.
Most endocrine disorders are caused by abnormal calcium levels in the blood while the bones are largely made of calcium. Hence, both doctors would usually need to work with the calcium levels in the blood and bones respectively.

A group of individuals from a larger population can migrate to a new area and establish a colony, which will be highly susceptible to genetic drift. This is known as
Answer:
Founder effect.
Explanation:
Migration refers to the movement of a group of people or other living organisms from one geographical region (location) to another geographical destination or colony in search of better living conditions, food, water supply, work or social amenities.
According to the founder effect, a group of individuals or living organisms from a larger population can migrate to a new area in search of better living conditions and establish a colony, which will be highly susceptible to genetic drift.
In a forest ecosystem, spotted owls make their homes in the cavities of dead trees. Thissame habitat is home to the rodents that the owls feed on. Human activities, such as logging,have caused the population of the spotted owl to decline. From this information, what statement BEST explains the relationship between humans and the spotted owl
Options are given in the comment section:
Answer:
The correct answer is - Humans have taken away resources needed by the owls, so there are fewer owls.
Explanation:
In this question, it is established that the trees are the habitat for the owls, and also these trees help in their food resources as these trees are habitat of rodents also.
By logging, humans destroy the habitat of both owls and rodents they feed on and important for their growth and survivability. Humans have caused the removal of required resources for the owls therefore, there are fewer owls.

ILL GIVE BRAINLIST PLS HELP
Answer:
1.In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.
2.Survival of the fittest is a simple way of describing how evolution (the process by which gradual genetic change occurs over time to a group of living things) works. It describes the mechanism of natural selection by explaining how the best-adapted individuals are better suited to their environment.
A cloned mammal is made by removing the DNA from the unfertilized egg of an egg donor, replacing it with DNA from a cell of a mature animal, and then implanting that cell into the uterus of a surrogate mother. The cell then divides and behaves as if it were a regular embryo. Answer the following question(s) regarding a clone.Of whom is the baby a clone?
Answer:
The mature animal
Explanation:
The baby would be a clone of the mature animal whose DNA was placed in the unfertilized egg before being implanted into the uterus of a surrogate mother.
The DNA of the egg donor has been removed and replaced with the DNA of the mature animal. The surrogate mother is just a mere carrier and has no biological relationship with the clone. The only organism with biological relationship with the clone would be the one that donates its DNA, which in this case is the mature animal.

The main role of the ________ is to increase the binding ability of RNA polymerase to the lac operon promoter region.
Answer:
catabolite activator protein (CAP)
Explanation:
Catabolite activator protein (CAP) is a homodimeric transcriptional activator required for transcription initiation of catabolite-sensitive genes in Escherichia coli. CAP contains a ligand-binding domain at its N-terminus and a DNA-binding domain at its C-terminus. CAP activates transcription by binding at target DNA sites on promoter sequences, thereby enhancing the ability of the RNA polymerase to bind and initiate transcription. CAP binds cyclic AMP (cAMP) to increase CAP’s affinity to DNA and thus activates the transcription of genes for catabolism, such as the lactose (lac) operon genes (the lac operon is a set of genes that encode for enzymes taking part in lactose metabolism).
