What s unsaturated fatty acid?Unsaturated fats are commonly biosynthesized by a one of a kind dehydrogenation response called desaturation. The science of this change is wonderful in its selectivity.
The development and use of novel robotic tests (deutero-, fluoro-, thia-containing substrate analogs) has prompted a more refined comprehension of how unsaturated fat desaturases and related compounds complete their super particular oxidation science. The stereochemistry and request of hydrogen expulsion has been inspected for various solvent and layer bound desaturses.

2. What structure caused rotifers to be called wheel animals or wheel bearers?
1 the foot
2 the corona
3 the brain
4 the stomach
Answers
The structure that caused rotifers to be called wheel animals or wheel bearers is the corona.
Rotifers are also known as wheel animals or wheel bearers because of the corona structure around their mouth region.
Some rotifers are sessile and live inside tubes or gelatinous holdfasts that are attached to a substrate. Other rotifers migrate around a substrate through inch worming.
This is because when corona is seen in a sequential coordinated movement, it resembles the structure of a wheel, although it does not rotate in reality.
Therefore, we conclude that rotifers are called wheel animals or wheel bearers due to the presence of the corona structure.

which of the following is a property of a reversible cholinesterase inhibitor? group of answer choices
Answers
The property of reversible cholinesterase inhibitor is: (1) that it enables parasympathetic stimulation for a finite period of time.
Cholinesterase inhibitor is a group of chemical compound that breaks down the neurotransmitter acetylcholine. They perform there function by binding to the enzyme cholinesterase. The examples are donepezil, galantamine, rivastigmine, etc.
Parasympathetic stimulation is the activation of the body's mechanism of bringing down the body to its normal condition like the lowering of the elevated heart rate. This is done by the stimulation of the M2 receptors present in the muscle cells of the body, particularly the cardiac and the smooth muscles.

interpret what data means about the otter’s role in the kelp forest. what is the percent fish in diet? (otters present) what is the percent fish in diet? (otters absent) what is the percent of invertebrates in diet? (otters present) what is the percent of invertebrates in diet? (otters absent)
Answers
In general, otters play a crucial role in maintaining the health of kelp forests. They are considered a keystone species because they feed on sea urchins, which are known to graze on kelp.
Without otters, sea urchin populations can grow unchecked and damage the kelp forest ecosystem. By keeping sea urchin populations under control, otters help maintain the balance between kelp and other organisms in the ecosystem.
The percentage of fish and invertebrates in the otter's diet can vary depending on their location and availability of prey. Otters are known to be opportunistic feeders and will consume a variety of prey depending on what is available. Studies have shown that otters can consume a range of invertebrates, including crabs, clams, and snails, as well as fish species such as rockfish and herring.
In general, when otters are present, there may be a lower percentage of sea urchins and a higher percentage of fish and invertebrates in the ecosystem.
Conversely, when otters are absent, the sea urchin population may grow unchecked, leading to a decline in kelp and potentially impacting other species that rely on the kelp forest ecosystem.

Where does rna not produce during replication
Answers
Answer:
This diagram shows an RNA molecule entering a cell and then replicating itself. It’s the SARS-CoV- 2 virus, which most people call COVID. It uses RNA instead of DNA as it’s genetic material; that’s common among viruses.
Many RNA-based viruses don’t use DNA at all to replicate, though some like HIV do.
In order for SARS-CoV-2 RNA to replicate there must be an enzyme called either RNA-dependent RNA polymerase or RNA replicase. RNA-based viruses produce a version of this enzyme so their genetic material can be copied.
SARS-CoV-2 uses a single stranded version of RNA but some other viruses use double stranded RNA that’s entirely analogous to double stranded DNA.
Modern animals, plants, and bacteria all use DNA as their genetic material, probably because DNA is more stable, but the very first living things probably used RNA.

Answers
A chromosomal deletion that affects a blood cell, deactivating a crucial gene involved in development would be passed onto a living fertile offspring if it happened in a parent.
The mutation below that would be passed onto a living fertile offspring if it happened in a parent is the chromosomal deletion that affects a blood cell, deactivating a crucial gene involved in development.
Chromosomal deletions involve the loss of a segment of DNA from a chromosome. If this deletion occurs in a germ cell (such as an egg or sperm cell) that is involved in reproduction, it can be passed on to offspring. In this case, if the deletion affects a crucial gene involved in development, it can have significant implications for the offspring's health and development.
The other mutations described do not necessarily have a direct impact on the genetic material that is passed on to offspring. An insertion mutation in an egg cell that deactivates a gene for hair color, a silent mutation in the genes of pancreas cells coding for insulin, or DNA substitution errors that occur in somatic cells resulting in skin cancer is not typically inherited by offspring, as they do not occur in the germ cells responsible for reproduction.

which of the following statements about the clonal selection theory of immune system function is false?
-a. antigens are recognized by receptor proteins inside the lymphocyte
-b. an activated lymphocyte makes many copies of itself in response to an infection
-c. cloned cells persist after the pathogen is eliminated
-d. each lymphocyte recognizes one antigen
Answers
The false statement about the clonal selection theory of immune system function is statement A, “antigens are recognized by receptor proteins inside the lymphocyte.” This statement is false because antigens are actually recognized by receptor proteins on the surface of the lymphocyte.
The clonal selection theory of immune system function states that when antigens enter the body, they are recognized by receptor proteins on the surface of the lymphocyte. This triggers the activation of the lymphocyte, which will then make many copies of itself in response to the infection. The cloned cells will persist in the body even after the pathogen has been eliminated. Each lymphocyte has the ability to recognize one antigen.
The clonal selection theory of immune system function is the basis for the human body’s ability to respond and protect itself from disease. It is a complex process that allows the body to recognize, fight, and remove foreign invaders, therefore protecting us from harmful bacteria and viruses.
