Answer:

Due to its spreading nature.

Explanation:

Transboundary environmental threats like pollution is a problem for both parties i. e. one that is producing pollution and the other which is not producing it, because pollution can't remain at one place and spread from one part to another part of the earth due to open environment. So due to its spreading, it affected both the producing and non-producing parties.

Answer:

Even when pollution originates on one side of a border, it often spreads through the environment beyond the point of origin, becoming a shared problem. It is important to track the sources of pollution to identify the policies and sources for prevention efforts, but regardless of the source of pollution, once a border area becomes polluted, the pollution is a health threat for all individuals on either side of the border.

Hippos and whales may look different in many ways, but they are actually each others' closest living relatives—sharing a common ancestor that lived about 55 million years ago.

Propranolol is a medication that belongs to a class of drugs known as beta blockers. It works by blocking the effects of adrenaline on the beta receptors in the body, thereby reducing heart rate, blood pressure, and the workload on the heart. Propranolol is commonly used for the treatment of various cardiovascular conditions and migraines. However, it is not useful in the treatment of hypotension.

Hypotension refers to low blood pressure, and propranolol is not typically prescribed for this condition. In fact, propranolol's ability to lower blood pressure is one of its primary therapeutic effects. Therefore, using propranolol in patients with hypotension can further decrease blood pressure and potentially cause adverse effects, such as dizziness, fainting, or impaired circulation.

On the other hand, propranolol is effective in treating the following conditions:

1. Angina Pectoris: Propranolol helps manage angina, which is chest pain or discomfort caused by reduced blood flow to the heart muscles. By reducing heart rate and blood pressure, propranolol can decrease the workload on the heart and improve blood flow to the heart muscles, relieving angina symptoms.

2. Hypertension: Propranolol is commonly prescribed for hypertension, which is high blood pressure. By blocking beta receptors, propranolol reduces the force and rate of the heartbeat, leading to a decrease in blood pressure.

3. Migraine: Propranolol is used as a prophylactic (preventive) treatment for migraines. It helps reduce the frequency and severity of migraine attacks by stabilizing blood vessels in the brain and preventing excessive dilation, which can contribute to migraine symptoms.

4. Myocardial Infarction (Heart Attack): Propranolol is sometimes prescribed following a heart attack to reduce the risk of future cardiovascular events. By decreasing heart rate and blood pressure, it can help prevent strain on the heart and reduce the likelihood of recurrent heart attacks.

In summary, propranolol is useful in the treatment of angina pectoris, hypertension, migraine, and myocardial infarction, but it is not indicated for the treatment of hypotension. It is essential to consult a healthcare professional for appropriate diagnosis and treatment recommendations.

Allelic combinations of different genes may differ between parents and their offspring and a heterozygous phenotype is the same as a homozygous dominant phenotype.

You have a heterozygous genotype for that gene if the two versions are dissimilar. Having one gene for red hair and one allele for brown hair, for instance, would indicate that you are heterozygous for hair color. The expression of certain features depends on the interaction between the two alleles. Allele pairings are referred to as heterozygous and homozygous, respectively. The term "homozygous" refers to people who have two copies of the same allele (RR or rr). The term "heterozygous" refers to an individual organism with multiple alleles (Rr). An organism can be homozygous dominant or homozygous recessive depending on whether it possesses two copies of the same allele in the dominant or recessive chromosome. When an organism possesses two distinct alleles of the same gene, it is said to be heterozygous.

All of the answer choices would change the allele frequencies of a population. The correct answer is (D).

Allele frequencies are the relative proportions of different alleles (variants of a gene) in a population. Allele frequencies can change due to a number of factors, including:

Genetic drift: This is the random change in allele frequencies from generation to generation. It is caused by the fact that not all individuals in a population will reproduce, and the alleles that are passed on to the next generation are determined by chance.

Natural selection: This is the process by which individuals with certain alleles are more likely to survive and reproduce than individuals with other alleles. This can lead to changes in allele frequencies over time.

Mutation: This is a change in the DNA sequence of a gene. Mutations can create new alleles, and they can also change the frequency of existing alleles.

Gene flow: This is the movement of alleles from one population to another. It can occur when individuals move from one population to another, or when pollen or seeds are transferred from one population to another.

In the case of the island population, the allele frequencies would change due to genetic drift. This is because the population is isolated and there is no gene flow from other populations. This means that the only way for new alleles to enter the population is through mutation.

In the case of the tall people, the allele frequencies would change due to natural selection. This is because tall people are more likely to reproduce than short people. This is because tall people are seen as more attractive and they are more likely to find a mate.

In the case of the DNA, the allele frequencies would change due to mutation. This is because DNA is not stable and it can change from generation to generation. This means that new alleles can be created and the frequency of existing alleles can change.

Overall, all of the answer choices would change the allele frequencies of a population. Therefore, the correct option is D.

The process of evolution that involves a change in the DNA sequence that leads to evolutionary change is called a mutation.

A mutation is a sudden and lasting alteration in the DNA sequence that can influence genetic variation. Changes in the DNA sequence can influence phenotype, which may or may not have an effect on an organism's fitness. Mutations occur spontaneously, either from errors in DNA replication or from exposure to mutagenic agents. Mutations may happen in either coding or non-coding regions of the DNA, and they can be either silent or expressed.

Evolution is a natural process that results in the gradual change of inherited characteristics in populations over generations. It is the process of alteration in the inherited characteristics of species over successive generations. In other words, it is the process of gradual changes that happen to species over time as they adapt to their environments. It can be defined as a change in the gene frequency in a population over time.

Answer:

Chloroplast absorbs sunlight and it is used to make feed for the plant together with water and carbon dioxide gas. Chloroplasts are used to generate the free energy stored in ATP and NADPH via a photosynthesis process.

Explanation:

The site of photosynthesis action is chloroplast within a plant cell consisting of two chlorophyll molecules (PS1 and PS2), which have been embedded in the thylakoid membranes. The chloroplast consists of two chlorophyll molecules (photosynthetic pigments responsible for the green color of chloroplast). Each chlorophyll molecule absorbs light, caused to depart the chlorophyll molecules. This absorbs two electrons from each phenotype. PS2 electrons pass through the transportation chain for electron carriers, a series of redox reactions that release the energy used to synthesize ATP via Photophosphorylation/Chemiosmose (as the H+ ions diffuse through the stalked particles ATP, which changes the shape and catalysts, the electrochemical gradient diffuses down through the stalky particle ATP synthase).

Then these electrons replace the electrons lost in PS1. PS2 electron is replaced by photolysis electron, which when light strikes chloroplast, splitting the water into oxygen gas, H+ ions, and electron enzymes in the thylakoid space are catalyzed. The PS1 electrons combine to create NADPH with H+ ions and NADP (reduced NADP). These are the light-dependent photosynthetic reactions in chloroplasts. In the light-independent reactions, the NADPH and ATP are created. A pile of thylakoids is known as granum.

The light-independent processes take happen in the stroma. This is the site of carbon fixation; CO2 reacts with RUBP to generate GP (glycerate-3-phosphate) which is catalyzed by the enzyme RUBISCO (the most abundant enzyme in the world) (the most abundant enzyme in the world). The NADPH and ATP from the light-dependent processes convert GP to GALP (glyceraldehyde 3-phosphate). Two out of every 12 GALP molecules produced are used to synthesize glucose that can be employed either in breathing or in cellulose-forming condensation polymerization to add extra strength to the planted cell wall. The other GALP molecules are returned to RUBP.

DNA is necessary for the production of proteins as well as the regulation, metabolism, and reproduction of the cell.

In a population of 50 individuals, the frequency of the h1 allele can be determined by looking at the number of individuals with each hair texture. Curly (h1h1) hair accounts for 25 individuals, wavy (h1h2) hair accounts for 15 individuals, and straight (h2h2) hair accounts for 10 individuals.

To determine the frequency of the h1 allele, we can use the following formula: (2 x number of individuals with curly hair) + (number of individuals with wavy hair) = total number of h1 alleles.

In this case, the formula is (2 x 25) + 15 = 65. Thus, the frequency of the h1 allele in this population is 65/100, or 0.65.

This result is expected, as the h1 allele is dominant and is present in both the curly and wavy hair textures. The h2 allele is only present in the straight hair texture, which accounts for a minority of the population. This is an example of incomplete dominance, where neither allele is completely dominant over the other.

In conclusion, the frequency of the h1 allele in this population of 50 individuals is 0.65. This is an example of incomplete dominance, where neither allele is completely dominant over the other.
