Mutations are rare and can occur in body cells.

Mutations are changes in the DNA sequence of an organism.

They can occur in both body cells and reproductive cells, meaning they can be passed down from generation to generation.

Mutations can be beneficial, harmful, or have no effect on an organism's fitness.

While some mutations can lead to diseases, others can help an organism adapt to its environment or improve its chances of survival.

However, most mutations are rare and do not have a significant impact on the organism.

Therefore, it is not accurate to say that mutations are always harmful.

Germline mutations specifically occur in reproductive cells and can be passed down to offspring.

Answer:

Dissolved oxygen refers to the level of free, non-compound oxygen present in water or other liquids. It is an important parameter in assessing water quality because of its influence on the organisms living within a body of water

Don’t worry, everything is gonna be fine :)

Answer: then it’s d there is less oxygen in cool water

Explanation:

There are many explanations for Michael's observation that fish breathe less frequently in cold water. However, his hypothesis that the fish returns to the cold water and requires less oxygen seems possible.

Fish are cold-blooded animals, which means their environment controls their body temperature. Their metabolic rate, activity level, and oxygen requirements decrease as water temperatures drop.

As a result, fish can slow down in cold water, reducing their oxygen demand and reducing their breathing rate.  Oxygen solubility may also play a role in whether fish breathe less in cold water. As the water temperature decreases, the ability of oxygen to dissolve in the water also decreases. Because of this, cold water can have less oxygen available, which can cause fish to breathe more slowly to compensate for the lack of oxygen.

Because fish need oxygen to digest food, they are likely to eat and breathe less. It's basically a joke that the fish are resting because fish don't have an obvious resting cycle and will move and swim when they are resting.

Finally, Michael's hypothesis that fish breathe less in cold water is plausible as it suggests that fish slow down and don't need as much oxygen.

The greenhouse effect is a natural process that warms the Earth's surface.

When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

The absorbed energy warms the atmosphere and the surface of the Earth causing green house effect .

Answer:

The greenhouse effect occurs when radiation from a planet's atmosphere warms the planet's surface to a higher temperature than it would be without the atmosphere. Radiatively active gases emit energy in all directions from a planet's atmosphere.

The minimum number of mirrors one could use to redirect the beam around the obstacle, so it hits the wall in the same place assuming the laser pointer must remain still is two mirrors.

One of the practical applications of plane mirrors is in the construction periscopes.

Similar to the periscope, in the case of the obstacle to the laser beam, two plane mirrors can be used.

One mirror is placed in front of the obstacle at an angle such that the beam is diverted to the second mirror placed at a second position so as to redirect the beam to the point.

Therefore, the minimum number of mirrors one could use to redirect the beam around the obstacle, so it hits the wall in the same place assuming the laser pointer must remain still is two mirrors.

Explanation:

1. If the individual with the dominant phenotype has an affected parent with a recessive phenotype.

2. If the individual with the dominant phenotype has affected offspring with a recessive phenotype.

In a pedigree, two situations can help determine the genotype of an individual with a dominant phenotype.

1. If an individual with the dominant phenotype has offspring with a recessive phenotype, it indicates that the individual must be heterozygous (carrying one dominant and one recessive allele).

This conclusion is drawn because the recessive phenotype can only be expressed when an individual has two copies of the recessive allele.

2. Another situation is when both parents have the dominant phenotype, but they produce offspring with the recessive phenotype.

This scenario suggests that both parents are heterozygous (carrying one dominant and one recessive allele), and the recessive phenotype appears in their offspring due to the inheritance of two recessive alleles.

By analyzing these patterns in the pedigree, we can make inferences about the genotype of individuals exhibiting dominant phenotypes.

The correct answer is - Photosynthesis takes carbon from the atmosphere and brings it to the geosphere and into plants.

Explanation:

Photosynthesis is the process that involves converting light energy to chemical energy stored in the form of sugars with the help of carbon dioxide and water as reactants.

The carbon is pulled from the atmosphere in the form of carbon dioxide for the process to the geosphere and then used by the plants (biosphere). In plants, it is trapped by the chlorophyll present in chloroplasts and water is entered in the light-dependent reaction and carbon dioxide is used in the light-independent reaction.

Answer:

The correct answer is given below:

Explanation:

ATP synthesis takes place in the mitochondria cell organelle in the eukaryotic cells, however, a small part of ATP generation takes place in other cell regions but most of the ATP synthesis is occurs in the inner membrane of mitochondria which makes it energy house of the cell.

ATP is formed by the addition of phosphorus to ADP and this process is called phosphorylation.

Each bond of the adenosine and its three phosphates has stored energy in their covalent bonds. The last two phosphates have a high amount of energy in their bond.

The macromolecule involved in how hemophilia is passed is DNA, specifically the genes carried on the X chromosome. The inheritance of hemophilia follows a pattern influenced by the presence or absence of the hemophilia gene on the X chromosome.

The macromolecule involved in how hemophilia is passed is DNA, specifically the genetic material carried on the X chromosome.

Hemophilia is an inherited bleeding disorder caused by a mutation in one of the genes responsible for producing clotting factors in the blood. The genes involved in hemophilia, such as the F8 gene (hemophilia A) or F9 gene (hemophilia B), are located on the X chromosome.

The X chromosome is one of the two sex chromosomes, with females having two copies (XX) and males having one copy (XY). Since hemophilia is a recessive trait, it typically affects males more often than females. This is because if a male inherits a defective X chromosome carrying the hemophilia gene, he will develop the disorder since he does not have a second X chromosome to compensate for the mutation.

In females, who have two X chromosomes, hemophilia can be passed on if they inherit a defective X chromosome from both parents. These females are carriers of the hemophilia gene and may not exhibit symptoms themselves but can pass the mutation to their offspring.

The inheritance of hemophilia follows a specific pattern, with affected males having an X chromosome with the hemophilia gene and unaffected males having a normal X chromosome. Female carriers have one normal X chromosome and one X chromosome with the hemophilia gene.

It is an example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness.

Explanation:

Natural selection:  

The population contains both superior as well as an inferior organism where natural resources are limiting so it will cause competition between organisms. As a result of competition, it will select superiors, and inferiors are deleted and they are given reproductive advantages. Due to this reproductive advantage new population emerges. It is more suitable for the environment.  

Natural selection divides into three parts that are directional, disruptive, and stabilizing selection.

The given question is the example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness. Directional selection will not lead to fixation of cheater genotype. This is because cheating can be controlled through high relatedness in social groups, resulting from kin discrimination.  

It is controlled through positive pleiotropy, where the cooperation gene has an additional vital function. Cheating will be controlled if stalk vs. spore is a result of environmental, not genetic factors. An example, spore fate can be a result of the position in the mitotic cell cycle.

The allele that determines the phenotype with respect to a particular gene is the option A. dominant allele.

In genetics, alleles are alternate forms of a gene that occupy the same position (locus) on a chromosome. Each individual inherits two alleles for each gene, one from each parent. The interaction between these alleles determines the expression of the gene and ultimately the phenotype, which refers to the observable characteristics or traits of an organism.

A dominant allele is one that exerts its effect even if there is only one copy present in the individual's genotype. It masks the effect of the recessive allele, which is only expressed when two copies of the recessive allele are present.

When an individual possesses a dominant allele for a particular gene, it determines the phenotype associated with that gene. This means that the trait associated with the dominant allele will be expressed, regardless of whether the other allele in the pair is dominant or recessive. Therefore, the correct answer is option A.
