2.Write any two adaptive features of rat.​

Answer:

Explanation:

This question is incomplete. However, what is described in this question is a method of DNA damage repair mechanism. The method described is called base excision repair. Generally, glycosylases play important roles in base excision repair (as they detect and remove these damaged bases).

One thing that can be considered while identifying the bond to be broken is the codon that will be formed after the removal of base. If this codon (a three base sequence) will still produce the same protein as when a normal cytosine was present.

NOTE: During this base excision repair, a glycosylase will detect and remove the damaged cytosine. Once removed, the remaining nucleotide backbone (of the removed cytosine) is also removed and the gap is filled and sealed by other enzymes in this repair mechanism.

Answer:

Total ATP molecules produced = 94 molecules of ATP

Explanation:

Myristoyl-CoA, is a saturated fatty acid with 14 carbons which has been activated for oxidation by attachment to coenzyme A. When it has undergone complete oxidation, it will yield 7 acetyl-CoA molecules and 6 FADH₂ and 6 NADH molecules each.

Each of the 7 acetyl-CoA molecules obtained from its initial oxidation enters into the citric acid cycle and is completely oxidized to yield further ATP and  FADH₂ and NADH molecules.

The overall yield of ATP from the various enzymatic steps is shown below:

Acyl-CoA dehydrodenase = 6 FADH₂

β-Hydroxyacyl-CoA dehydrogenase = 6 NADH

Isocitrate dehydrogenase = 7 NADH

α-Ketoglutarate dehydrogenase = 7 NADH  

Succinyl-CoA synthase = 7 ATP (from substrate-level phosphorylation)  

Succinate dehydrogenase = 7 FADH₂

Malate dehydrogenase = 7 NADH

Note: 1 FADH2 molecule yields 1.5 ATP; 1 NADH molecule yields 2.5 ATP molecules. Therefore,

Total ATP  from FADH₂ molecules = 13 * 1.5 = 19.5  

Total NADH molecules = 27 * 2.5 = 67.5

Total ATP molecules produced = 19.5 + 67.5 + 7  = 94

Total ATP molecules produced = 94 molecules of ATP

Cheetahs are one of my favorite creatures.

Cheetahs' physical characteristics, such as their speed, agility, and razor-sharp claws, have probably evolved over time to help them survive in their habitat.

Cheetahs are swift hunters that can pursue prey in wide-open savannahs. Their keen claws enable them to grip the ground while racing quickly.

Cheetahs may need to adjust to new environmental conditions in the future, including greater competition for food and water and habitat loss brought on by human activities.

They could need to change their hunting techniques, pick other prey, or even broaden their range to encompass new ecosystems.

Additionally, they might need to strengthen their defenses against illnesses and other environmental stresses in order to survive in a changing world.

Atomic fission is the process through which energy is produced. The right answer is C.

Atomic splitting produces a particular form of energy known as fission. It is a nuclear process in which a huge quantity of energy is released along with the splitting of an atom's nucleus into two or more smaller nuclei.

In fission, neutrons are used to hit heavy atomic nuclei, such as uranium-235 or plutonium-239, creating an unstable nucleus.

Then, this nucleus splits into two or more smaller nuclei, releasing more neutrons and a substantial amount of energy in the process.

Thus, the correct option is C.

Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.

A mutualism occurs when two species have a long-term relationship that benefits both of them (+/+ interaction). Some fungi, for example, create mutualistic relationships with plant roots. The plant may photosynthesize and gives fixed carbon to the fungus in the form of sugars and other organic compounds.

The presence of several species in an ecosystem balances it. The species in an ecosystem interact with one another in some way. For example, the existence of a plant species will offer food for the numerous herbivores found in an ecosystem. A predator may consume a variety of prey. As a result, the existence of diverse prey reduces the likelihood of a species becoming extinct in the ecosystem. As a result, all creatures in an ecosystem are dependent on one another in some way.

Cells communicate with one another through a variety of mechanisms, including chemical signaling and direct cell-to-cell contact. These communication processes are essential for many physiological functions, such as tissue repair and immune response.

One important aspect of cell communication is the signaling pathways that are activated by different signaling molecules. These pathways control various cellular functions, such as cell growth, differentiation, and death. Dysregulation of these pathways can lead to various diseases such as cancer, autoimmune disorders, and developmental disorders.

Clinical considerations related to cell communication include:

Explanation:

Clinical considerations related to cell communication include:

Cancer: Cancer cells often have mutations in signaling pathways that lead to uncontrolled cell growth and proliferation. Targeting these signaling pathways with drugs can be an effective way to treat cancer.

Autoimmune disorders: In autoimmune disorders, the immune system mistakenly attacks the body's own cells. This can be due to a malfunction in the signaling pathways that control the immune response.

Developmental disorders: Many developmental disorders, such as Down syndrome, are caused by changes in the signaling pathways that control cell differentiation and growth.

Tissue repair: Inadequate cell communication during tissue repair can lead to chronic inflammation and non-healing wounds.

Inflammation: Inflammation is a normal response to injury, infection, and other stimuli. However, chronic inflammation can contribute to various chronic diseases such as cancer, heart disease, and diabetes.

It's important to note that more research is needed in this field to fully understand the clinical implications of cell communication and to develop effective treatments for related diseases.

The best summary of the outcome of Redi's experiment is that the experiment provided evidence against spontaneous generation by demonstrating that maggots do not spontaneously generate from decaying meat when it is isolated from flies.

Francesco Redi conducted an experiment in the 17th century to challenge the prevailing belief in spontaneous generation, which proposed that living organisms could arise spontaneously from non-living matter.

In his experiment, Redi set up two groups of jars containing meat. One group was covered with gauze to prevent flies from accessing the meat, while the other group was left uncovered.

Over time, Redi observed that maggots appeared only in the uncovered jars where flies had access to the meat, while the covered jars remained free of maggots.

This led Redi to conclude that maggots were the offspring of flies and did not arise spontaneously from the meat.

His experiment provided empirical evidence against the theory of spontaneous generation and contributed to the development of the concept of biogenesis, which states that living organisms come from pre-existing living organisms.

The weak bonds that occur when atoms and molecules are temporarily attracted to each other by virtue of their proximity and charge are Vander Waal forces.

Van der Waals forces are weak forces that keep electrically neutral molecules together. At some point, these molecules have an induced dipole, which means they have a partially positive and partially negative charge for a brief period of time, leading them to attract one other.

They are forces of Van de Waals: The movement of electrons causes dispersion forces between non-polar molecules (union between atoms of the same element or between atoms with very little electronegativity difference).

Therefore, Vander Waal forces are the weak bonds formed when atoms and molecules are temporarily attracted to each other due to their proximity and charge.

Answer: Epididymis

Explanation: The sperms are stored in the spiral structure of the epididymis for maturation and then released.

Sperm cells mature in the structure called the seminiferous tubules within the testes. After developing in these tubules, the sperm move to the epididymis where they continue to mature and then during ejaculation, they exit the body via the vas deferens. This highlights the different stages of sperm development and maturity in the male reproductive system.

Sperm cells develop to maturity in a structure called the seminiferous tubules, which are coiled inside the testes. The least developed sperm are located at the periphery of the tubule, while the fully developed sperm are in the lumen. Within the walls of these tubules, the sperm cells are mixed with Sertoli cells, also referred to as 'nursemaid cells', which protect the germ cells and support their development.

Once the sperm cells have developed, they exit the seminiferous tubules and move to the epididymis where they continue their maturation process. The epididymis is a coiled tube located on the top and posterior of the testes. Upon ejaculation, the mature sperm leave the epididymis, travel through the vas deferens, and form the ejaculatory duct.

A neuron is a type of cell that can take in stimuli from other neurons via its numerous dendrites, such as sensory input. Where there appears to be a high amount of intricacy, approximation, or ambiguity, computers do better than humans. Some species don't actually have a nervous system, such sea sponges. Others, like jellyfish, lack a real brain and instead have what is known as a "nerve net," which is a network of distinct but linked nerve cells (neurons).

Both a central nervous system (CNS), which consists of a small "brain" and two nerve cords, and a peripheral nervous system (PNS), which is made up of a network of nerves that extends throughout the body, are present in flatworms of the phylum Platyhelminthes. Insect neural systems vary in complexity and degree of centralization. It includes ganglia, the ventral nerve cord, and the brain (clusters of connected neurons). These ganglia are capable of controlling actions and behaviors independently of the brain.

These populations do not evolve. No evolutive forces are acting on them.

Assuming a diallelic gene, frequencies are

Allelic frequencies

Genotypic frequencies

In a population in equilibrium,

We will consider these equations to solve the problem.

Because we have the frequency of the homozygous recessive genotype, we can get the allelic frequency.

Now, by clearing the equation p + q = 1, we can get the dominant allele frequency. And then, the frequency of the homozygous dominant genotype.

Finally, we can get the frequency of the heterozygous genotype
