transition zone
HELP
Answer:
c. neritic zone
A seabed or the ocean floor is the underwater structure that lies on the bottom of the ocean or sea. The oceanic floor comprises continental inclines and elevations, mid-ocean ridges, trenches etc.
The correct answer is:
Option C. Neritic zone.
This can be explained as:
The shallow region of the ocean is called the neritic zone that extends up to 660 feet of depths.The sunlight is available and plankton's and other organisms can make their food.It is the most prolific zone of the ocean because of the abundance of nutrients.Organisms like sea anemones, crabs, sponges, dolphins, jellyfish etc. prevail in this zone.Therefore, the neritic zone is the section of the ocean floor.

A population contains short plants and tall plants. The short plants are not able to compete with tall plants for sunlight. The tall plants, however, are more susceptible to wind damage. Which type of selection will this population of plants most likely experience? directional selection disruptive selection species selection stabilizing selection
Answer: D
Explanation: A population contains short plants and tall plants. The short plants are not able to compete with tall plants for sunlight. The tall plants, however, are more susceptible to wind damage.
Which type of selection are the plants experiencing?
directional selection
disruptive selection
If tall and small plants coexist in a population. Short plants are unable to compete for sunlight with tall plants. However, tall plants are more vulnerable to wind damage, it experiences stabilizing selection, hence option D is correct.
What is stabilizing selection?A form of natural selection when genetic diversity declines as a population stabilizes on a given trait value.
Disruptive selection's opposite is stabilizing selection. It favors the intermediate variants rather than people with extreme traits.
The more severe phenotypes are typically eliminated through stabilizing selection, which leads to the reproductive success of the average or typical phenotypes.
Therefore, stabilizing selection this population of plants most likely experience.

In the diagram, the feature labelled C is only found in plant cells. What is it called?
Answer:
Should be the Chloroplast
Explanation:
Since its green and only plants have it, the way they produce energy is using Chloroplasts..
In the diagram, The cell organelle labeled as c is the chloroplast
The plant cell contains structures that are cell walls, chloroplast, vacuoles that are absent in an animal cell.
Reason:
cell wall present on the outside of the plasma membrane labeled as Evacuoles are the single but largest cellular structure in the plant cell and are present in the center.Chloroplasts:
The chloroplast is an organelle found in plants and other photosynthetic organisms.The chloroplast contains chlorophyll that gives the plant its green color.Chloroplasts capture light energy to conserve free energy in the form of ATP and reduce NADP to NADPH through photosynthesis.The chloroplasts also have a double outer membrane. chloroplasts are minute flattened granules.Thus, In the diagram, The cell organelle labeled as c is the chloroplast

A silver mine recently opened along the foothills of a mountain. The mine's primary method for extracting silver from the surrounding rock is heap leaching. Which of the following hazards does this process most likely pose to the environment?
I. Atmosphere contaminated with heavy metals
II. Soil contaminated with cyanide
III. Surface water contaminated with sediment
Answers:
I only
II only
III only
I and II only
Soil contaminated with cyanides is the hazard which is the most likely pose to the environment. Thus, the correct option is B.
What is Cyanide contamination?Silver mining is the extraction of silver metal from minerals, starting with mining. Because of this silver, which is often found in the intimate combination with other metals, its extraction requires more elaborate and complex technologies.
Cyanide in the landfills can contaminate the underground water. Hydrogen cyanide, sodium cyanide, and potassium cyanide are the major forms of cyanide which are most likely to be found in the environment as a result of industrial activities. Hydrogen cyanide is a colorless gas with a faint, bitter, almond-like odor. Concentrated acids and cyanides are used to dissolve metals from the rock which are picked up in rainwater.
Therefore, the correct option is B.
