Answer:
The fertilized ovule becomes the seed, and the ovary becomes the fruit.
Explanation:
Answer AND Explanation:
Gametogenesis is the formation of gametes. Formation of sperms also called spermatogenesis takes place in the testes while formation of eggs also called oogenesis takes place in the ovary. Oogenesis in females begins before birth, however maturation of the eggs take a very long time and is only complete after fertilization. In males sperm formation only occurs after puberty.
Answer:
A few examples could be an increase in food, an increase in shelter, a decrease in predators, or more land.
Herbicides are a broad category of pesticides that are used to get rid of undesirable plants like weeds and grasses that hinder the development and productivity of desired agricultural crops. Both 2,4-D and 2,4,5T are also known as 2,4-Dichlorophenoxyacetic acid and
- Herbicides like 2,4-D and 2,4,5-T are also referred to as auxin-type herbicides or plant growth regulators. Auxins are hormones that affect cell division and elongation in order to control cell growth.
- Auxins are required by plant cells in the proper concentration for growth and development. If auxin levels are too low, plant growth is not promoted at all, and if levels are too high, plant growth is excessively stimulated.
- Most grasses are not killed by 2,4-D and 2,4,5 T, but broadleaf weeds are. It moves to the plant's meristems after being absorbed through the leaves.
- These herbicides affect the tissues' cells, causing them to continually divide and proliferate. The plant finally dies as a result of this unchecked, unsustainable growth, which also causes stem curling and withering of the leaves.
Thus, by promoting cell division, these compounds act as herbicides.

Answer:
A. Each organism had a different parent that passed on a set of unique genetic instructions.
Explanation:
Organisms can either be single-celled or multicellular. According to this question, a student collects a sample of water from a pond near her home. She then examines a drop of the water under a microscope and noticed it contains four very differently shaped single-celled organisms.
The single-celled organisms are of different shapes because they are from different parents, which passed on a set of unique genetic instructions via their genes to them. Organisms of the same species from the same parent will possess the same shape because they contain same gene which makes them look and behave similar.
However, in this case, the four different shaped single-celled organisms are of DIFFERENT SPECIES and hence, contain individual unique genes that makes them so
