Embryonic development is a complex process that is defined by many factors. But in general, we can say that it is affected by 2 important sources of change: genes and the environment. Genes hold the necessary information that will dictate how the embryo will develop and the characteristics it will have. However, the environment will define which genes will be expressed and carry out their function and which genes will be "dormant or silenced" and have no effect on the development of the embryo. Therefore, both are equally important, since on the one hand, if the genes did not exist, the embryo would not have the necessary information to develop. Meanwhile, on the other hand, if the cells did not respond to the inhibitory stimuli of the environment, for example, they would multiply unceasingly leading to the malformation or death of the embryo.

Mutations that lead to protein disruption will produce defective proteins by affecting the first level (amino acid sequence). Defective proteins are non-functional.

A mutation is any alteration in the nucleotide sequence of the genome (i.e., the genetic material) of an organism.

Mutations in genes may lead to the generation of different types of proteins that encode for different amino acids.

The first level of protein structure is the amino acid sequence, thereby mutations may affect this level.

The characteristic that is unique to seed-producing plants, in addition to seeds, is (c) pollen.

Pollen is a unique characteristic of seed-producing plants. Pollen grains are produced by the male reproductive organs of seed plants and are responsible for the transfer of male gametes to female gametophytes in the process of fertilization. This enables seed-producing plants to reproduce sexually without requiring water or external agents to transfer sperm, as is the case with non-seed plants.

Sporopollenin is a tough, durable polymer that forms the outer layer of pollen grains and spores, protecting them from environmental damage. Lignin is a complex organic polymer that provides structural support to cell walls in plants. Megaphylls are large, flat leaves with a highly branched vascular system found in most plants. While these characteristics are important in the biology of plants, they are not unique to seed-producing plants. Only pollen is a unique characteristic of seed plants.
Pollen is a small, powdery substance containing the male reproductive cells (gametes) of seed-producing plants. It is produced in the male reproductive organs (anthers) and is responsible for fertilization by transferring sperm to the female reproductive organs (ovules) during pollination.

The cytoplasm is where glucose is broken down into two pyruvate molecules by glycolysis. The carbon molecule's decomposition into carbon dioxide is completed by the citric acid cycle.

Through oxidative phosphorylation, the mitochondria produce the majority of the adenosine triphosphate (ATP) that is produced during the metabolism of glucose. This is a complicated reaction that is fueled by the proton gradient that runs across the inner membrane of the mitochondria and is made by mitochondrial respiration.

Upon entering the mitochondrial matrix, a complex of multiple enzymes transforms pyruvate into acetyl CoA, releasing carbon dioxide and forming one molecule of NADH.

The shape of the vegetable oil changed but the volume did not.

What is state of matter?

Solids, liquids, and gases all fall under the category of states of matter. Solids are made up of tightly packed particles. In contrast to gases, where they are scattered, liquids have more particle mobility. Particles in chemistry can be molecules, ions, or even atoms.

It is important to understand that only when matter gains or loses energy will its state change. The vegetable oil is simply poured in this instance from a bottle into a cup, then into a bowl. No energy was gained or lost in the process; the only thing that will change is the oil's shape, as the bowl it is currently in is not the same shape as the bottle.

Explanation:

Multiple origins of replication on the DNA molecules of eukaryotic cells serve to shorten the time necessary for DNA replication.

The origin of replication is where the leading and backward strands separate to form single-stranded DNA segments that serve as templates for replication.

Eukaryotic chromosomes often have multiple origins of replication. Given the size of eukaryotic chromosomes, this is necessary for full reproduction to occur on time. Each of these origins defines a replica, or DNA sequence, that reproduces from a particular origin. The copies do not reproduce at the same time, so care must be taken to ensure that the copies are used only once during the cell cycle.
