Answer:

c

Explanation:

C. greater differences between niches.

A greater difference between niches results in less direct competition for resources. When species occupy different niches, their roles in the environment do not overlap significantly, and they can coexist with less interspecific competition. In contrast, if species have similar niches, they are in direct competition with each other, leading to reduced population sizes and potential extinction.

Different reproductive habits of species and greater day/night temperature differences have no direct effect on competition.

Excessive reactive oxygen species (ROS) disrupt the balance between kinase and phosphatase enzymes, leading to sustained activation of epidermal growth factor (EGF) signaling and uncontrolled cell division in cancer.

Reactive oxygen species (ROS) are highly reactive molecules that are byproducts of normal cellular metabolism. However, when ROS levels become excessive due to various factors such as oxidative stress, they can cause damage to cellular components, including DNA. In the context of cancer, high levels of ROS can disrupt the delicate balance between kinase and phosphatase enzymes involved in signal transduction pathways, particularly the epidermal growth factor (EGF) signaling cascade. ROS-induced oxidative modifications can lead to sustained activation of receptor tyrosine kinases (RTKs), as the phosphatase enzymes that normally remove phosphate groups to reverse the cellular response are inhibited. This persistent activation of EGF signaling promotes uncontrolled cell division, contributing to the development and progression of cancer.

Explanation:

Histone proteins are involved in regulating gene expression through various chemical changes that occur on the protein surface. These changes can affect the structure of chromatin, the complex of DNA, and the proteins in which genes are packaged. The most common changes include acetylation, methylation, phosphorylation, and ubiquitination.

Acetylation of histone tails by histone acetyltransferases (HATs) neutralizes the positive charge on the lysine residues, leading to a more open chromatin structure that allows for transcription factors to bind and activate gene expression. Methylation of histone lysine and arginine residues by histone methyltransferases (HMTs) can either activate or repress gene expression, depending on the specific site and degree of methylation. Phosphorylation of histone tails by kinases can also affect gene expression by changing the chromatin structure and recruiting other regulatory proteins. Lastly, ubiquitination of histones can target them for degradation or affect chromatin structure.

Overall, these chemical changes in histone proteins can have a profound impact on gene expression, and dysregulation of histone modifications has been implicated in a wide range of diseases, including cancer.

Running from the glomerular capsule to the tip of the medullary pyramid is a series of ducts that, together, is referred to as renal tubule. The correct answer is c).

The renal tubule is a long, winding tube that begins at the glomerular capsule (also known as Bowman's capsule) and extends through the cortex and medulla of the kidney, ending at the tip of the medullary pyramid. Along the way, the renal tubule is composed of different segments, each with its own unique structure and function.

These segments include the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting ducts. Together, they play a vital role in filtering and reabsorbing fluids and electrolytes from the blood, as well as secreting waste products for excretion in the urine.

The vasa recta refer to the network of blood vessels that supply the renal medulla, while the collecting duct is the final segment of the renal tubule where urine is concentrated before being excreted through the ureter. The glomerulus is a tuft of capillaries located within the glomerular capsule that filters blood to form the initial filtrate that enters the renal tubule.

The correct answer is c).

Answer:

When NAD+ takes an electron from glucose, it becomes NADH, the reduced form of the molecule.

Explanation:

NADH transports this electron to mitochondria where the cell can take the energy that is stored in the electron. NADH then donates the electron to oxygen, converting it back to NAD+.

The equation pairs which illustrates a favorable energetic coupling in a cell are equation 1 & 3 and equation 2 & 3.

A positive ∆G means that the reaction is non spontaneous and will require energy from outside. Negative ∆G means that the reaction is spontaneous and will occur on its own.

Coupling of reactions-

equation 1 and 2-

∆G1=-7kcal/mol, ∆G2=-14.8kcal/mol

∆G total= -21.8kcal/mol( favourable reaction)

Equation 2&3-

∆G2=-14.8kcal/mol, ∆G3=+3.3kcal/mol

∆G total=-11.5kcal/mol(favourable)

Equation 3 and 4-

∆G3=+3.3kcal/mol, ∆G4= +7kcal/mol

∆G total=+10.3kcal/mol(unfavorable)

Equation 1 and 4-

∆G1=-7kcal/mol, ∆G4=+7kcal/mol

∆G total= 0(reaction will be in equilibrium)

Equation 1 and 3-

∆G total=(-7+3.3)kcal/mol

=-4.3 kcal/mol(favorable)

The correct answer is when one population cannot interbreed with the other population as there will be speciation.

Speciation is an evolutionary method via way of means by which a brand new species come into being. A species is a set of organisms that can reproduce with each other to supply fertile offspring and is reproductively remoted from different organisms.

Thus it is clear that when one population cannot interbreed with the other population then one species of organisms becomes two species.

One result of researchers attempting to teach human languages to apes and African gray parrots is that these animals have shown some level of language acquisition. In the case of apes, such as the famous chimpanzee named Washoe, researchers used American Sign Language (ASL) to communicate with her.

Washoe was able to learn and use over 100 ASL signs, demonstrating the potential for apes to acquire and understand human language.
Similarly, African gray parrots, like Alex, were taught to use a form of communication called the "Model/Rival" technique. Alex was able to learn and understand a large vocabulary of English words and phrases, and even demonstrated the ability to form novel combinations of words to communicate his needs and desires. These interactions with apes and African gray parrots indicate that these animals have the cognitive ability to learn and use human language to some extent. However, it is important to note that their language abilities are still limited compared to humans.

The likelihood that the first two offspring of the cross will have congenital analgesia would be 1/16

For autosomal recessive traits, two recessive alleles are needed for the trait to manifest while one recessive allele means heterozygosity.

In this case, let us assume that congenital analgesia is represented by the allele b; heterozygous individuals will, thus, be Bb.

            Bb    x    Bb

          BB   Bb   Bb   bb

Probability of producing unaffected offspring = 3/4

Probability of producing affected offspring = 1/4

Likelihood of the first two offspring having congenital analgesia = probability of first having congenital analgesia and the second having congenital analgesia

    = 1/4 x 1/4

In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their establishment. They interact with native species by competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-. They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species. They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.
