A accomplish this task, and muscle C does the opposite of A, then muscle A is a antagonist to prime mover.
What is antagonist muscle?muscles can only pull. They typically work a joint in pairs because of this. When a body part is moved, one of the pair's muscles contracts; when the body part is brought back to its starting position, the other muscle in the pair contracts.
Antagonizing pairs of muscles are those that function in this way. When two muscles are antagonistic, one contracts while the other relaxes or lengthens. The muscle that is lengthening or relaxing is referred to as the antagonist, while the muscle that is contracting is referred to as the agonist.
Therefore, A accomplish this task, and muscle C does the opposite of A, then muscle A is a antagonist to prime mover.

What is Fertilization in plants?Fertilization is defined as the process of sexual reproduction, which occurs after pollination and germination which can be defined as the fusion of male gametes called pollen with female gametes called as ovum to form diploid zygote. It is a physio-chemical process that occurs after pollination of the carpel.
Steps of Fertilization occur in Plants
1. Pollination
2. Germination
3. Fertilization
Fertilization occurs through the pollen tube opening into the ovule through the micropyle and bursting into the embryo sac where the male nucleus fuses with an egg nucleus inside the ovule to form a diploid zygote, which then swells and develops into a fruit. These plants are similar in appearance when grown from seed but with the tuber method they will appear identical but not with the mother.
Thus, they will look the same because the plants grown from seeds are genetically identical to one another but not to the mother plant. So, the correct option is (A).

Answer:
c
Explanation:
All the others would begin to kill off a population
We respect Dr. Trudeau and all those earlier scientists who did the best they could within the contemporary understanding of the problem they addressed and utilizing the materials and technology they had at hand. Modern-day biologists like to talk about resistance/susceptibility genes and patterns of inheritance, rather than family blood. They think about infectious disease in terms of microbes and pathogenicity, rather than speaking of bad humors. They have identified vitamins and other nutrients that are abundant in some foodstuffs and lacking in other that are essential for optimal immune function. Without the benefit of such modern formulations, Dr. Trudeau, by a disciplined application of scientific curiosity and careful, clever methodology, shed light on each of these concerns, light that helped to illuminate the minds of scientists who came after. Still, a look at his original paper leaves us wondering, were the rabbits genetically identical? Probably not! Why? Were they all of the same sex and age? Couldn’t he have given the animals kept on short rations just a smaller amount of the same varieties of food available to the animals fed abundantly—after all, there might be some important nutrient missing in potatoes. In light of the title of the paper, why not measure bacterial numbers in the rabbits on post mortem rather than just survival time? (In a subsequent paper, he did exactly that.) Once you start critiquing an experiment from 100 years ago, or 10 years ago, or sometimes even last year, it’s hard to stop.

increasing intracellular cAMP leads to smooth muscle relaxation by: Group of answer choices inhibiting IP3 channels, leading to decreased Ca2 in the sarcoplasm and reduced contraction. Increasing the relative activity of MLCP, leading to a decrease in tension. Activating K channels, increasing K leaking out of the cell which hyperpolarizes it and decreases the likelihood of Ca2 entry. Lower levels of MLCK activity, leading to decreased contraction.
Answer:
1. Inhibiting IP3 channels, leading to decreased Ca2 in the sarcoplasm and reduced contraction.
2. Increasing the relative activity of MLCP, leading to a decrease in tension.
3. Activating K channels, increasing K leaking out of the cell which hyperpolarizes it and decreases the likelihood of Ca2 entry.
Explanation
In smooth muscle, cyclic AMP (cAMP) mediates relaxation because cAMP inhibits a specific kinase required for myosin light chain protein (MLCP) phosphorylation, thereby triggering contraction in the smooth muscles. It has been shown that cAMP inhibits 1,4,5-trisphosphate (IP3)-dependent calcium ions (Ca 2+) release by activation of the cGMP-dependent protein kinase (PKG). PKG proteins act to modulate Ca2+ oscillations by stimulating sarcoplasmic Ca2+-ATPase membrane proteins, increasing Ca2+ in the sarcoplasmic reticulum stores and Ca2+ efflux from the cells, and activate voltage-gated potassium (K) channels, thereby leading to membrane hyperpolarization and reducing Ca2+ entry through Ca2+ channels.

Which is the general equation for cellular respiration?
A. carbon dioxide + water + energy --> oxygen + glucose
B. glucose + energy --> carbon dioxide +oxygen + water
C. carbon dioxide + glucose --
--> water + oxygen + energy
D. glucose + oxygen --> water + energy + carbon dioxide
Answer:
D. glucose + oxygen ⇒ water + energy + carbon dioxide
Explanation:
The reactants of cellular respiration, or the substances that are used for the beginning of the chemical process, are sugar (glucose) and oxygen. The products, or the results of cellular respiration, are water, carbon dioxide, and ATP energy. Thus, D is the answer.
The general equation for cellular respiration is glucose + oxygen --> water + energy + carbon dioxide, which is in option D. So, here, the correct answer is option D.
Glucose is a sugar molecule that serves as the primary source of energy for cells. It is derived from the breakdown of carbohydrates in the diet or can be produced through other metabolic processes. Oxygen is required for cellular respiration as the final electron acceptor in the electron transport chain. It is obtained from the air through breathing or from other sources in organisms that do not respire aerobically. During cellular respiration, glucose and oxygen undergo a series of metabolic reactions in different stages, including glycolysis, the citric acid cycle, and oxidative phosphorylation. The correct option is option D.

Question: What is an adaptation?
Answer:
an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment
Explanation:
An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.
