Answer:
Angiosperms have seeds with an 3n endosperm due to double fertilization.
Explanation:
- Double fertilization is found only in flowering plants.
- In angiosperms, the female gametophyte does not grow after reaching eight nucleate stage.
- After fertilization and triple fusion, the zygote and primary endosperm are created and further growth of embryo sac continues.
- Triple fusion is the fusion of two haploid polar nuclei of female gametophyte and one male nuclei. This results in a 3n nucleus.
- The developing embryo obtains nutrition from the endosperm.
- If fertilization fails no endosperm is formed.

Answer:
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition
Explanation:
Forming glycogen as energy storage in the liver is an example of anabolism.
<h3>What is anabolism?</h3>
Anabolism is a metabolic process that consists of the construction and manufacture of more complex molecules from simpler molecules. This contributes to cell growth and energy storage for tissue maintenance.
The process of anabolism can be seen in processes such as the formation of triglycerides or glycogen for energy reserves within cells or in the formation of muscle proteins, given in the sports world.
In these anabolic processes, a lot of energy is consumed since much more complex molecules are being manufactured.
It is a totally opposite and complementary process to catabolism, in which these complex molecules are broken down into much simpler molecules and the release of energy is generated.
For a correct homeostasis of the body, these two processes have to be balanced and work in a <u>complementary way.</u>
Therefore, we can confirm that forming glycogen as energy storage in the liver is an example of anabolism.

The answer is C
The more plants there are, the more consumers there are. If there aren't enough plants, the consumers have no way of getting energy, and therefore cannot survive. The species also matters, because certain species of plants can only be eaten by certain species of consumers.
