In a population of cats, a gene that controls an observable trait has several different alleles. Which of the following best explains how genetic drift might affect the genetic makeup of this cat population over time?
It is a directed process, so it might cause an increase in the gene pool's allele frequencies.
It is a nonselective process, so it might cause an allele to disappear from the gene pool by chance.
It is a random process, so it might cause a population to reach genetic equilibrium.
It is a selective process, so it might cause an increase in the population's genetic variation.
Answer: It is a nonselective process, so it might cause an allele to disappear from the gene pool by chance brainliest?

Which of the following best describes evidence from comparative biochemistry that supports the theory of evolution? (4 points)
Different mechanisms of reproduction exist within the same species.
Different metabolic pathways exist within the same species.
Different species have the same genetic code.
Different species have the same number of chromosomes.
Answer:
1. Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.
2. Anabolism & Catabolism
3. Nearly everybody has the same genetic code. Although the sequences of bases in their DNA (and thus in the messenger RNA that is made from their DNA) vary between species and even between individuals within a species, almost all of them use the same code.
4.Yes, two or more species can have the same number of chromosomes. ... There's much more to differentiating between species than number of chromosomes. For one example, there are proteins present on eggs which 'match up' with proteins on sperm, and these are very specific.

Answer:
C: Converting radiant energy into chemical energy.
Explanation:
Only plants (producers) in a typical ecostystem can convert radiant energy into chemical energy.
Answer:
Converting Radiant energy into Chemical energy.
Explanation:
There are two main purposes for plants. 1. Providing oxygen 2. serving as producers. As we know, plants take in the sunlight from the sun and make glucose with it. This glucose in its form is chemical energy that benefits both the plants, or the consumers that eat them, or some parts of the plant. It does not talk about oxygen or atmosphere except for nitrogen, which they actually get from the ground. Therefore, Converting Radiant energy into Chemical energy would be the right answer.

What is reflex arc?A reflex arc is a neural pathway that mediates a reflex action. It is a rapid and automatic response to a specific stimulus that does not require conscious thought or decision-making from the brain. When a sensory receptor in the body, such as the skin or muscles, is stimulated, a nerve impulse is transmitted to the spinal cord, where it is processed by an interneuron.
The interneuron then sends a signal through a motor neuron to the effector, such as a muscle, causing a rapid and involuntary response, such as pulling your hand away from a hot stove. This entire process occurs without conscious control from the brain, allowing for quick and protective responses to potentially harmful stimuli.

Determine whether each statement correctly describes the myocardial action potential and the pacemaker potential. 1. Because the pacemaker potential occurs during systole, it can also be called systolic potential. (Click to select) 2. The pacemaker potential is the relatively slow, spontaneous depolarization in the SA node. (Click to select) 3. Myocardial cells produce their own action potentials after being stimulated by action potentials originating in the SA node. (Click to select) 4. Myocardial action potentials are characterized by a spike and then slow depolarization. (Click to select)
Answer:
1. False
2. True
3. True
4. False
Explanation:
In mammals, the contraction of the heart muscle is caused by pacemaker cells localized within the sinoatrial (SA) node. These cells rhythmically generate slow electrically-induced action potentials due to their slow rate of depolarization. The pacemaker cells generate the action potentials that propagate through the heart and trigger the contraction of myocyte cells (i.e., myocytes simply conduct the action potential waves). The slow depolarization of pacemaker cells occurs during diastole, i.e., during the period of relaxation of the heart muscle.
why do you produce carbon dioxide when working out?
Answer: The lungs bring oxygen into the body, to provide energy, and remove carbon dioxide, the waste product created when you produce energy. The heart pumps the oxygen to the muscles that are doing the exercise. When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.
