The sequence of the terms describing genetic material in descending order, from largest to smallest is:
Genome > Homologous pair of chromosomes > A single DNA molecule > a gene for hair color.
What is Genetic material?The genetic material of an organism may be defined as a molecule that stores the genetic information associated with the organism and passes it from one generation to the next.
The genome comprises all the genes in an organism. Such genes are located or found on the chromosomes that long DNA molecules associated with proteins. A gene is any stretch that is found on a DNA molecule that carries several different deviations.

indicate structural adaptations of Mitochondria for its function
Mitochondria(Mt) are the cell's "power stations" because the energy currency for the metabolic processes in the cell is synthesised inside this organelle via aerobic respiration. This process is known as oxidative phosphorylation. Mt is a double membraned, semi-autonomous organelle.
The mitochondrion's structure is specially tailored to the function it performs:
The outer membrane contains carrier proteins that allow pyruvate produced during glycolysis to be transported from the cytoplasm.The electron transport chain(a series of protein complexes) and ATP synthase are located in the inner membrane to transfer electrons and ATP production respectively.The inner membrane is folded into numerous pockets called cristae, which raises the surface area: volume ratio.When proton accumulation occurs, the small intermembrane space between two membranes increases the hydrogen gradient.Matrix is the core chamber containing the necessary enzymes and pH for the Krebs cycle(oxidation of acetyl-CoA derived from pyruvate) to take place.To learn more, refer:

Why do plants contain the
greatest amount of energy in the
food pyramid?
Answer:
According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis. They are the primary producers and primary source of food energy. The flow of energy is unidirectional from producer to consumer level.
Explanation:
According to the energy pyramid, autotrophs or producers have the highest energy content. Autotrophs are plants that prepare their nourishment through photosynthesis. They are the key producers and energy sources for food. Energy flows unidirectionally from producer to consumer.
What is an Energy pyramid?A trophic pyramid, also known as an ecological pyramid, is an illustration of the flow of nutrients through an ecosystem. It is a graphical representation of the proportions of energy available in an ecosystem at each trophic level, or feeding level.
The pyramid of energy is often divided into tiers, with primary producers, like power plants, at the bottom. Above the primary producers come the principal consumers, which include herbivores that eat plants. Then there are secondary consumers, like carnivores that eat herbivores, and so on.
Thus, according to the energy pyramid, autotrophs or producers have the highest energy content.

1. Short-term hormonal influences on animal behaviour usually occurring late in life - activational effects
2. A technique that associates a natural response to a stimulus to an unrelated stimulus; also called Pavlovian conditioning -- classical conditioning
3. The study of animal behaviour in its natural environment - ethology
4. When an animal learns not to respond to a stimulus - habituation
5. Finding a solution to a once unsolvable problem - insightful learning
6. Learning that has taken place but is dormant until a situation requires it - latent learning
How, explain your answer?
Activational effects are the sudden or immediate temporary transient effects of behavioural changes due to the influence of hormones, especially the gonadal or these hormones. The behaviour change in male animals due to an increase in male se hormonal activity can be referred as an activational effect.
Classical conditioning facilitates learning of a behaviour when a conditioned stimulus is associated with an unconditioned stimulus leading to a conditioned response. Animal training by pairing a new unconditioned stimulus with an already known conditioned stimulus, a new conditioned response of behaviour change can be observed.
Ethology refers to the scientific zoological study (includes both laboratories as well as natural field studies) of animals' behavior with relation to their natural environment. It studies and compares about animal behavioral processes changes under various disciplines like ecology, anatomy, evolution etc.
Habituation is an associative learning process that results when an animal learns to resist a stimulus and not to respond to it after repeated exposure.
Insightful learning occurs when various parts of a problem are analyzed and their relationship is understood to arrive at the solution suddenly. Animals must look at a situation as a whole, and observe and analyze it to solve the problem. Some animals like chimpanzees can learn through insightful learning
Latent learning occurs without any associated reinforcements. Animals learn new behaviour through latent learning.
Thus, this could be the answer.

please help me :C
Answer:
At the beginning of the follicular phase, the lining of the uterus (endometrium) is thick with fluids and nutrients designed to nourish an embryo. If no egg has been fertilized, estrogen and progesterone levels are low. As a result, the top layers of the endometrium are shed, and menstrual bleeding occurs.
