The heat produced during oxidative phosphorylation depends on the efficiency of the electron transport chain, as well as the coupling between electron transport and ATP synthesis.

Because the electron transport chain is linked to ATP synthesis through the proton motive force across the mitochondrial inner membrane, the proton gradient generated by electron transport must be conserved. The de-coupling of oxidative phosphorylation causes the electron transport chain to generate only heat energy.

When some molecules uncouple oxidative phosphorylation from the electron transport chain, there is heat still being made because of the mechanism of uncoupling. There are special transporters called uncoupling proteins that help to transfer the proton gradient, causing ATP synthesis to be slowed down or halted. The transfer of protons across the membrane, however, creates heat as an alternative way to dissipate the energy released by the electron transport chain.

Molecules that cause uncoupling or de-coupling of oxidative phosphorylation from electron transport chain are called uncoupling agents. They transport protons from the intermembrane space to the mitochondrial matrix, bypassing ATP synthase, which causes an uncoupling of ATP synthesis from electron transport. This makes the energy of the electron transport chain become solely dissipated as heat.

Answer:

splits

Explanation:

a) In order to transcribe the segment of DNA, it is important to note that this process is important for gene expression as a protein. An enzyme called RNA polymerase moves along the DNA until the end of the gene, releasing the mRNA. The DNA has two strands: one that goes from 5' to 3' direction, and another one that goes from 3' to 5' direction. The one that's used for transcription will always be the 3' to 5' one, so we already have the correct strand to work with, as it is a 3' to 5' strand.

However, the mRNA will be assembled in the 5' to 3' direction. Using the same complementary base-pairing rules as in DNA, we will pair Cytosine (C) with Guanine (G), but as there is no Thymine (T) in RNA, we will pair Adenine (A) with Uracil (U).

Therefore, the sequence o mRNA read in the 5' to 3' direction is:

5' CUAUGGAAACACAUCAGUAGAA 3'

b) The starter codon is the AUG codon of a messenger RNA (mRNA). Therefore, the sequence of amino acids will start to be decoded there.

The stopper codon can be one of the three following options: UAA, UAG or UGA. In this case, we can only find the UAG codon.

The codons, then will be:

AUG GAA ACA CAU CAG UAG

Then, we can say that the amino acids translated will be:

Met Glu Thr His Gln

(Methionine - Glutamine - Threonine - Histidine - Glutamine

c) In eukaryotes, transcription occurs inside the nucleus of the cell and translation occurs in the cytoplasm.

The use of Trichoderma harzianum as a biological agent to control plant diseases is important to humans because it can reduce our dependence on toxic and expensive chemical agents.

Chemical agents can have harmful effects on the environment and human health, and their use can be expensive for farmers. By using T. harzianum as a biocontrol agent, farmers can reduce their use of chemical agents and instead rely on a natural and environmentally friendly solution. This can also result in healthier and better-tasting crops, as well as a more sustainable and affordable farming industry.

Additionally, the use of T. harzianum can encourage farmers to plant and harvest a wider variety of crops, contributing to a more diverse and resilient food system.

The primary functions of whales include feeding, reproduction, communication, and migration.

Whales are primarily filter feeders or predators, depending on the species.

Filter-feeding whales, such as baleen whales, have baleen plates in their mouths that allow them to filter out small prey, such as krill or small fish, from large volumes of water.

Predatory whales, such as toothed whales, hunt and feed on various marine organisms, including fish, squid, and marine mammals.

Reproduction is another important function for whales. Most whale species have a gestation period of several months, with females giving birth to a single calf.

The calves are nursed with milk from their mothers and rely on their care for a period of time until they become independent.

Communication is vital for whales, as they rely on vocalizations to communicate with other members of their pod.

Whales produce a variety of sounds, including songs, clicks, and whistles, which serve purposes such as mating, social interactions, and navigation.

Migration is a common behavior observed in many whale species. Whales undertake long-distance migrations, often covering thousands of kilometers, to reach feeding grounds in nutrient-rich waters or to reproduce in specific breeding areas.

These migrations are driven by seasonal changes in food availability and environmental conditions.

In summary, the primary functions of whales encompass feeding, reproduction, communication, and migration, all of which are essential for their survival and successful adaptation to their marine environments.

An organism that has two different alleles of a given gene has a(n) heterozygous genotype. aneuploid dizygous heteromorphic heterozygous homozygous

Heterozygous genotypes are characterized by two different alleles of a particular gene. These alleles can be inherited from different parents or from the same parent, and this type of genotype is also known as a dizygous genotype.

An example of this is eye color; if an individual has one allele for blue eyes and one allele for brown eyes, they would have a heterozygous genotype. This type of genotype is important for producing genetic diversity, allowing for adaptations that can be beneficial to a species. It is also important to note that having a heterozygous genotype does not guarantee that the individual will express the traits of both alleles; rather, the individual will usually express the trait of the dominant allele.

Adaptation comes from new combinations of genes from parents and mutations in the DNA passed on to an organism. The correct options are A and D.

The process by which organisms adapt to their environment in order to increase their chances of surviving in that environment is known as evolutionary adaptation, or simply adaptation.

"The process by which a species or an organism steadily improves its acclimation to its environment is defined as adaptation."

The behavioral or physical characteristics of an animal that improve its ability to thrive in its ecosystem are referred to as adaptation.

DNA changes handed down to the organism provide adaptations in the form of new traits. Lethal or beneficial, mutations can give an organism new traits and improve its chances of surviving.

Crossing over and recombination lead to new gene combinations derived from the parents' genes. These novel genomic fusions result in adaptations.
