What kind of water is found in the benthic zone of a lake?
A. Shallow with many tide pools
B. Shallow with rooted plants
C. Warm and dense
D. Cold and dense
Answer: D
Explanation:
The kind of water found in the benthic zone of a lake is Cold and dense. The correct option is D.
What is the benthic zone of a lake?The benthic zone, which includes the sediment top and some subsurface layers, is the ecological region at the bottom of a body of water, such as an ocean, lake, or stream.
Benthic zones are too dark to enable photosynthesis, which explains why. The region cannot get sunlight because of the depth of the oceans above it. In this manner, photosynthesis is prevented, preventing plants from growing. Only decomposers and detritus feeders are therefore present in the benthic zone.
This indicates that it may begin at a shallow depth of a few inches and eventually descend to a depth of 6,000 meters as it crosses the abyssal plain at the ocean's bottom.
Therefore, the correct option is D. Cold and dense.

Humans and other animals regulate cell growth and cell division. Sort these cells by category:
Muscle cells Nerve cells Skin cells Blood-producing cells Digestive tract cells Cells that do not divide once they have developed
Cells that grow and divide throughout life
Answer:
Two Categories:
Cells that do not divide once they have developed
-Muscle Cells
-Nerve cells
Cells that grow and divide throughout life
-Skin cells
-blood-producing cells
-digestive tract cells
Explanation:
The nerve cells and some of the muscle cells like cardiac cells do not divide once they have developed, while the skin cells, the smooth muscle cells, the blood-producing cells, and the cells of the digestive tract cells grow and divide throughout life.
• The nerve cells and the cardiac cells rarely or not at all divide once they get developed.
• Of the muscle cell types, the smooth muscles cells exhibit the greatest tendency to regenerate all through life. The smooth muscle cells exhibit the tendency to differentiate and can grow in different ways.
• The skin cells possess the tendency to regenerate and grow throughout their lives. The dead skin cells continuously elevate to the surface of the body and get shed off, and get substituted by the new skin cells.
• Blood-producing cells also possesses the tendency to grow and divide all through life, the blood cells range from less than a day to several days, and are produced spontaneously by the division of common stem cell in the bone marrow.
• The intestine of the digestive tract is the most regenerative organ of the human body, possesses the tendency to regenerate its lining, that is, the epithelium after every 5 to 7 days.
Thus, the cardiac cells and nerve cells do not divide once they get developed, while the smooth muscle cells, the nerve cells, the blood-producing cells, and the digestive tract cells grow and divide throughout life.

ATP transports and releases energy within cells that can be used for many cellular processes. How does ATP make this energy available to the cell?
Answer:
Chemical energy that is stored in the food molecules such as sugars are converted into the chemical energy that is available for the cell to perform various cellular functions, it is stored in ATP known as the currency of the cell.
ATP has three phosphate groups attached to adenosine by a phosphoanhydride bond. When a cell requires energy it loses the third phosphate group and releases a huge amount of energy stored in the phosphoanhydride group and form ADP.
When the second phosphate group is lost by breaking the bond again energy is released again left AMP. The breaking of this bond takes place due to hydrolysis reaction

Describe the cycling of carbon in the carbon cycle as it passes through the living and non-living components of the ecosystem.(4 points)
The biogeochemical pathways by which the carbon content is maintained and balanced in the atmosphere and the earth is called the carbon cycle.
The purpose of the carbon cycle pathway through the living and non-living:The pathways depict the use of the carbon compound in different activities and sources through their natural origins. The main purpose of the cycle is to balance the carbon in the ecosystem of biotic and abiotic factors.
When the carbon passes through the biotic and abiotic factors the following takes place :Photosynthesis: the process by which the plants and other autotrophic organism produces food requires carbon dioxide as the main component and as a result yield glucose and oxygen important for living beings.Respiration: the process of inhaling and exhaling the gases from the organism is called respiration. The digested food and the inhaled oxygen in the organism's body release the carbon dioxide back into the environment.Decomposition: the dead plant's, microorganisms and animals, gets broken into the smaller organic and inorganic compounds that in turn releases the carbon dioxide into the atmosphere and the soil.Therefore, the carbon cycle goes on between the biotic and abiotic factors of the ecosystem.
