The leaves of plants have many specialized structures. Which statement explains the importance of the stomata and guard cells for the plant?
o They protect the plant from pests
o They are involved in plant reproduction
They work together to regulate water loss and gas exchange.
o They regulate the amount of water that enters the plant for cellular respiration
Answer:
They work together to regulate water loss and gas exchange.
They work together to regulate the loss of water and exchange of gases.
Stomata and guard cellsThe tiny pores or openings in plant tissue, which allow for the exchange of gases are known as stomata.
The unique cells, which surround stomata and work to close and open the stomatal pores are known as guard cells.
Both these helps a plant to take in carbon dioxide at the time of photosynthesis and also assist in reducing the loss of water by getting closed when conditions are dry and hot.
Thus, stomata and guard cells work together to regulate the loss of water and gas exchange.

Name the mechanism that caused the continents to move apart and summarize how scientists discovered it in 2-3 complete sentences.
Answer: Plate tectonics is now the widely accepted theory that Earth's crust is fractured into rigid, moving plates. In the 1960s, scientists discovered the plate edges through magnetic surveys of the ocean floor and through the seismic listening networks built to monitor nuclear testing, according to Encyclopedia Britannica.

Identify the phases of the eukaryotic cell cycle
Answer:
The division cycle of most eukaryotic cells is divided into four discrete phases: M, G1, S, and G2. M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs. The cell grows throughout interphase, which includes G1, S, and G2. The relative lengths of the cell cycle phases shown here are typical of rapidly replicating mammalian cells.

How many different gametes can be produced by a tall, yellow-seeded, purple-flowered, and wrinkled-seeded pea plant (TtYyPprr)?
A 2
B 4
C. 6
D. 8
Answer:
I think it could be either C or D
Six different gametes can be produced by a tall, yellow-seeded, purple-flowered, and wrinkled-seeded pea plant (TtYyPprr). Thus, option C is correct.
What is genotype?The genotype of the plant with yellow round seeds will be YYRR and produce YR gametes, while the genotype of the plant with green wrinkled seeds will be yyrr and produce yr gametes.
A true breeding plant always has identical alleles of a gene and is homozygous in nature. The genotype of the true-breeding parents with yellow round peas: YYRR. The genotype of the pure breeding parent plant with green wrinkled peas: yyrr.
Gametes are always pure which means that a gamete carries only one allele of a gene. Since both the parent plants are true breeding, there will not be any segregation of alleles during gamete formation. Therefore, the parent plant with yellow round peas "YYRR" would form all the gametes with "YR" alleles while the parent plant with green wrinkled peas "yyrr" would form all the gametes with "yr" alleles.
Therefore, Six different gametes can be produced by a tall, yellow-seeded, purple-flowered, and wrinkled-seeded pea plant (TtYyPprr). Thus, option C is correct.
