Plants adapted to dry, hot and arid climates are considered xerophytes. Examples include the entire yucca family, acacia trees, and mesquite trees.

Since mesophytes prefer moist, well drained soils, most crops are mesophytes. Some examples are corn (maize), cucurbits, privet, lilac, goldenrod, clover, and oxeye daisy.

Remains the same proton pumping rate electron transport rate, and rate of oxygen uptake. decreases or goes to zero rates of ATP synthesis, size of protein gradient.

Mechanistic studies have revealed that gramicidin A blocks ATP generation by inhibiting oxidative phosphorylation and glycolysis, leading to cellular energy loss and non-apoptotic cell death. Finally, gramicidin A effectively suppressed the growth of her RCC tumor xenografts in vivo.

Electron transport proton pumping and oxygen uptake are unaffected as they precede the proton gradient of oxidative phosphorylation. The proton gradient is reduced because protons flow back into the mitochondria via gramicidin rather than ATP synthase. Cellular respiration is the metabolic pathway that breaks down glucose to produce ATP.

The uncoupling protein is important for human newborns. Option E is not correct.

The uncoupling protein inhibits the formation of ATP in mitochondria by dissipating the potential energy of the organelle. It results in the loss of heat and is important for small mammals in cold climates and occurs mainly in adipose tissues or fat cells. The proton electrochemical gradient produced by the respiratory chain complexes is reduced by uncoupling proteins. This, therefore, verifies that only option E is not correct out of the options given in the question, because UCP has no relation with newborns.

Uncoupling protein 2 (UCP2), a mitochondrial transporter found in the inner membrane of mitochondria, separates substrate oxidation from ATP synthesis, allowing less ATP to be produced by the mitochondrial respiratory chain and causing the membrane potential energy to be lost.

Answer:

Denitrification is the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere.

Answer: Dopamine

Explanation:

Drugs of abuse such as methamphetamine and morphine increase the levels of dopamine in the central nervous system. Dopamine has a variety of functions but functions mainly in motivation and reward mechanism. People doing drugs of abuse create a pleasurable sensation in which there is a dopamine surge every time they use drugs. In the absence of drugs, the body "looks" for the pleasure thereby causing the person to be drug-dependent and addicted.

Drugs of abuse that are commonly abused by people are alcohol, cocaine, MA, heroin, marijuana, nicotine.

Most of these drugs increase the level of dopamine in the brain.

Dopamine is an amine neurotransmitter which generates feelings of pleasure and thus creates a sense of euphoria.

Further, this neurotransmitter is also responsible for reward behavior and thus generates a feeling of satisfaction in the abuser.

Answer: D. Dopamine

Explanation:

Dopamine is the neurotransmitter that has been classically associated with the reinforcing effects of drugs of abuse and may have a key role in triggering the neurobiological changes associated with addiction.

The air moves to the lungs during inspiration. The alveolar pressure must be lower than the atmospheric pressure for air to move to the lungs.

The lungs can take in air thanks to this difference in pressure. Inhaling, sometimes referred to as inspiration, is the initial phase. Inhalation causes the diaphragm to tighten and pull downward. The muscles in the space between the ribs tighten and pull upward. The thoracic cavity enlarges as a result, releasing internal pressure.

Reproductive isolation is defined as processes that prevent individuals of different populations from mating, survival or producing fertile offspring. Reproductive isolation is critical for driving speciation and maintaining species identity,

Explanation:

isolation is known to contribute to divergent evolution, resulting in unique phenotypes. Oftentimes morphologically distinct populations are found to be interfertile while reproductive isolation is found to exist within nominal morphological species revealing the existence of cryptic species. These disparities can be difficult to predict or explain especially when they do not reflect an inferred history of common ancestry which suggests that environmental factors affect the nature of ecological divergence. A series of laboratory experiments and observational studies were used to address what role biogeographic factors may play in the ecological divergence of Hyalella amphipods. It was found that geographic isolation plays a key role in the evolution of reproductive isolation and divergent morphology and that divergence cannot be explained by molecular genetic variation.

In flowering plants, harvesting energy from light and reproduction are functions of the shoot, and nutrient uptake and anchorage are functions of the root system.

The frequency of the recessive allele is 0.7.

As per the question, the percentage of homozygous recessive individuals = 49% or a frequency of 0.49. So, frequency of recessive allele is the square root of 0.49 = 0.7

The Hardy Weinberg rule states that in the absence of circumstances that promote evolution, the genotype and allele frequencies in a population remain constant. It claims that the binomial expansion of the square of the sum of p and q can be used to describe the total genotype frequencies. The binomial expression is as follows:

[tex](p+q)^{2}[/tex] = [tex]p^{2}[/tex] + [tex]q^{2}[/tex] + [tex]2pq^{}[/tex]

Explanation:

A typical adult would have to drink 566.6 cm³ more milk to get their RDA for calcium compared with the amount of milk needed to get their RDA for vitamin B-12

The volume of milk needed to meet the Recommended Daily Allowance for Calcium and  Vitamin B-12 is calculated as follows:

RDA for calcium = 1000 mg

500 cm³ of milk contains 600 mg

Volume of milk required for RDA calcium = 1000 * 500 / 600

Volume of milk required for RDA calcium = 833.3 cm³

RDA for Vitamin B-12 = 2.4 µg

500 cm³ of milk contains 4.5 µg

Volume of milk required for RDA  Vitamin B-12 = 2.4 * 500 / 4.5

Volume of milk required for RDA  Vitamin B-12 = 266.7 cm³
