Answer: it deals with synthetic or superficial genes and traits like color, markings, size, and speed.

Explanation: a good example of artificial selection is breeding dogs. people mix breeds to get these kinds of quality’s.

Artificial selection is the opposite of natural selection, in which organisms adapt to their environments without human intervention. So, the correct option is C.

Artificial selection, commonly known as selective breeding, is the intentional breeding of particular plants or animals by humans to advance certain desirable traits. On the other hand, natural selection occurs in the wild when organisms with favorable characteristics are more likely to survive and reproduce.

The term "artificial" in artificial selection refers to deliberate human manipulation of the reproductive process as opposed to allowing natural processes to occur. The use of nutrition, hormones or artificial insemination is not mentioned. A wide variety of traits, including color, markings, size, movement, and other physical or behavioral characteristics, are possible through artificial selection.

So, the correct option is C.

Answer:

Water is more effective for evaporative cooling than liquid methane since, it would result in a higher temperature drop for the same mass of liquid methane.

Explanation:

Since the heat of vaporization of water is 540 calories per gram and that of liquid methane is 122 calories per gram, for each gram of the water evaporated, 540 calories is lost while for each gram of liquid methane evaporated, 122 calories is lost.

Since a higher heat loss would result in a higher temperature drop, water is more effective for evaporative cooling than liquid methane since, it would result in a higher temperature drop for the same mass of liquid methane.

Answer:

Diffusion is the movement of particles from high to low concentration across different surfaces. It usually works better on wet surfaces because water molecules help particles move. Dry surfaces may not have enough moisture to help particles move, slowing or hindering diffusion. The surface type can also affect diffusion - porous materials allow for easier diffusion while dense materials restrict it.

Rosalind Franklin produced critical x-ray crystallography data for the modern model of DNA.

The DNA double helix was first conceptualized by British physicist Francis Crick and American biologist James Watson in the early 1950s. In this scientific "marathon," they were the first to reach the finish line, while others like Linus Pauling (who discovered protein secondary structure) were also looking for the right model.

Watson and Crick gathered and analyzed previously obtained data, combining it in novel and illuminating ways, rather than doing brand-new tests in the lab. Rosalind Franklin, a scientist working in physicist Maurice Wilkins' lab, provided them with some of the most important hints about the structure of DNA. Franklin was a master of X-ray crystallography, a potent method for figuring out the structure of molecules. When a molecule, like DNA, is subjected to X-rays in its crystallized form, part of the rays are refracted by the crystal's atoms, creating a diffraction pattern that reveals information about the structure of the molecule.

Considering the probabilities of these outcomes, the chance of having a child with blood type O is 50% if a man with blood type AB marries a woman who is heterozygous for blood type B.

To determine the probability of having a child with blood type O, we need to analyze the possible blood type combinations that can result from the parents' genotypes.

The man has blood type AB, which means he has both A and B antigens on his red blood cells. The woman is heterozygous for blood type B, meaning she carries one B allele and one recessive O allele. The possible genotypes for the man are AB (IAIB) and the possible genotypes for the woman are BB (IBIB) or BO (IBi).

When these two individuals have offspring, their children can inherit any combination of the parents' alleles. The possible combinations are as follows:

AB x BB: All children will have blood type B (IBIB), as both parents only carry the B allele.AB x BO: There is a 50% chance that each child will inherit the O allele from the mother, resulting in blood type O (ii). There is also a 50% chance that each child will inherit the B allele from the mother, resulting in blood type B (IBi).

Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.

Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.

Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.

Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.

The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.

Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.

This shows that Carlton has an impaired absolute threshold.

He could not detect the smallest quantity of a stimulus to differentiate between the smells.

Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.

This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.

Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

Answer:

Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).

Explanation:

Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).

Energy can neither be created nor be destroyed. The available energy within each trophic level is lost as heat and only 10% of the energy is utilized.

The 10% rule can be explained as:

1. Energy in the different trophic levels is passed and the rest of the energy is lost as heat.

2. The law suggests that only 10% of the energy is transmitted to different trophic levels.

3. Approximately 80%-90% of the energy is lost in the form of heat. The organisms utilize energy for metabolic processes and keep them warm.

Thus, the rest of the energy is lost as heat and only 10% of the energy is transferred to the next trophic level.

The brain and spinal cord are part of the central nervous system.

The electrical charges that act as nervous signals are called action potentials or nerve impulses.

Jellyfish do not have a brain. Instead, their nervous system is called a nerve net.

After nervous systems began to develop in bilaterally symmetric animals, some developed ventral nerve cords, while chordates developed dorsal nerve cords.

Skeletons that allow for movement by using muscles and squeezing liquid to change the body shape are called hydrostatic skeletons.

Exoskeletons do not grow with arthropods, and so occasionally must be shed and regrown from chitin.

Muscles move endo- and exoskeletons by contracting and relaxing.

Fertilization is the joining of two gametes called sperm and egg.

Answer:

11,400 years old

Explanation:

The total  number of atoms present at the beginning = number of C-14 + number of N-14 atoms.

Hence;

1500 + 500 = 2000 atoms = No

At time t, N = 500 atoms of C-14 remains

Since the half life of C-14 (t1/2) = 5700 years

N/No = (1/2)^t/t1/2

500/2000 =  (1/2)^t/5700

1/4 = (1/2)^t/5700

(1/2)^2 =(1/2)^t/5700

2 = t/5700

t = 2 * 5700

t = 11,400 years old

Explanation:

Metabolism is the sum of the physical and chemical processes in an organism by which its material substance is produced, maintained, and destroyed, and by which energy is made available.

Having a high metabolism means your body burns energy from food at a faster rate than others your age. This means that you require more energy from food in order to grow and develop.

A person with a "low" (or slow) metabolism will expend less calories when at rest and during exercise, necessitating a reduction in caloric intake.

How to get a fast metabolism:

While metabolism is partially determined by genetics, there are several things you can do to help increase your metabolism:

It's important to note that while these strategies may help increase metabolism, there is no one-size-fits-all approach. Consult with a healthcare professional to determine the best course of action for your individual needs.

if a high metabolism is the case, there is nothing or barely anything to fix.
