Answer:
metaphase
Explanation:
The phase which is shown in the figure is Metaphase. The correct option is B, metaphase.
Metaphase is a critical phase of mitosis, which is the process of cell division that leads to the formation of two genetically identical daughter cells. During metaphase, the chromosomes, which contain the cell's genetic material, align at the center of the cell in preparation for separation.
Metaphase phase of mitosis:
Chromosome Condensation: Prior to metaphase, during the preceding phase called prophase, the chromosomes condense. Each chromosome consists of two identical sister chromatids held together at a region called the centromere.Formation of the Mitotic Spindle: In metaphase, the centrosomes, which are structures located near the cell's nucleus, migrate to opposite ends of the cell. From each centrosome, microtubules extend and form a network called the mitotic spindle. Chromosome Alignment: The mitotic spindle exerts tension on the chromosomes, aligning them along the equator of the cell, known as the metaphase plate. Checkpoint Control: The cell possesses a checkpoint mechanism during metaphase, known as the spindle checkpoint or metaphase checkpoint.Once metaphase is completed, the cell proceeds to anaphase, during which the sister chromatids are separated and pulled to opposite ends.
Therefore, the correct option is B.

O Normal cells recognize signals that tell them to stop and start the cell cycle, but cancer cells
do not
Normal cells can invade other tissues, but cancer cells cannot
In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated
O Normal cells communicate with each other, but cancer cells do not

In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated. This is not a difference between normal cell division and cancer cell division. Thus, option B is correct.
What is Apoptosis?
Apoptosis is the process in which cells are destroyed or killed for the purpose of controlling their development and growth. The normal cells follow this process but the cancer cell do not response to it and keep growing.
Normal cells can invade other tissues, but cancer cells cannot. In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated.The difference between a normal cell and a cancer cell is that a normal cells undergo while cancer cells don't Also, normal cells respond to signals while cancer cells don't.
Cancer cells are grow in the absence of signals telling them to grow. Normal cells only grow when they receive such signals. Ignore signals that normally tell cells to stop dividing or to die which is the process known as programmed cell death.
Therefore, In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated. This is not a difference between normal cell division and cancer cell division. Thus, option B is correct.

Explanation:
Parents and their offspring are usually very similar, but always slightly different. For example, certain moths can have offspring with either dark or light wings. Almost everything else about the moths is nearly identical, but the wing color and pattern may look very different. If the moths live in a forest with trees that have very dark bark, which newborn moth would have a survival advantage, the light winged moth or the dark winged moth? A) The dark winged moth, because its color will help it fly away from predators. B) The light winged moth, because its color will help it fly away from predators. C) The dark winged moth, because its color will help it blend with the environment. D) The light winged moth, because its color will help it blend with the environment.

d. Plant cells contain a large vacuole that occupies much of the volume of the cell.
Answers
Answer:
d. Plant cells contain a large vacuole that occupies much of the volume of the cell.
Explanation:
The vacuole is a membrane-bound organelle which is often found in plant and fungi cells, as well as in certain bacteria, protists and animal cells. The vacuole is filled with water that forms a solution containing inorganic and organic compounds. The size of the vacuole may vary depending on the requirements of the specific cell type. In plant cells, vacuoles often occupy an important fraction of the overall cell volume and play key roles during growth and development, influencing diverse cellular functions ranging from photosynthesis to transpiration.

No, coyote will not become the apex predator.
Explanation:
No, coyote will not become the apex predator but greatly reduces the populations of foxes in order to reduce competition for available resources. Yes, The coyote population will decreases because t he gray wolf kills coyote to avoid competition for food resources. If another wolf is introduced to fit the same ni che, the coyote population will decrease because the wolf feeds on coyote. As the number of coyotes increase, the number of beavers will decrease because coyote feeds on beaver. If the gray wolf became extinct, the coyote population increases in that location due to no predator.

All healthy, highly productive ecosystems provide which of these essential ecosystem services that involve gases in the atmosphere?
A. Increasing carbon dioxide levels in the atmosphere by the action of plants and animals.
B. Removing carbon dioxide from the atmosphere and storing carbon in the tissues of organisms.
C. Removing water vapor from the atmosphere and using it to support plant growth.
D. Removing methane from the atmosphere and storing its carbon and hydrogen in the tissues of organisms.
Answers
Answer:
All healthy and highly productive ecosystems provide the essential ecosystem services that consist in removing carbon dioxide from the atmosphere and storing carbon in the tissues of organisms (option B).
Explanation:
The carbon cycle involves the path that this element has between the biosphere and the atmosphere.
As part of the carbon cycle, the carbon dioxide (CO₂) produced by the combustion of fossil fuels or organic matter and by the elimination of animals passes into the atmosphere, and must be removed.
Photosynthesis removes CO₂ from the atmosphere and converts it into organic compounds that are stored in plants. Plants, vegetables and fruits consumed by animals contain carbon that is incorporated into other living beings.
In a healthy and efficient ecosystem, CO₂ is removed from the atmosphere to become part of living beings, as organic matter.
The other options describe processes that are not related to the actual question formulation:
A. Atmospheric CO2 does not increase due to the action of plants.
C. Water vapor is not removed to contribute to plant growth, but rather the plants absorb water from the soil.
D. Methane is not removed from the atmosphere or incorporated into living systems.
