Explain mechanism of transportation in mollusca
Answer:
The mollusk circulatory system uses a heart to pump blood through the organism, and the respiratory system of aquatic mollusks centers around their gills. The heart pumps blood through blood vessels that lead from the gills into body cavities called hemocoels.

What is the process by which organisms become better suited to their environment to survive and reproduce?.
Which statement is true?
A cell that divides is called a parent cell and the two new cells are daughter cells
Two daughter cells combine to a create a parent cell
One daughter cell and one son cell are produced from each parent cell
A cell that divides is called a parent cell and the two new cells are a daughter cell and a son cell
Answer:
A cell that divides is called a parent cell and the two new cells are daughter cells
Hope this helps!
A cell that divides is called a parent cell and the two new cells are daughter cells. Thus, the correct answer is Statement 1.
When a parent cell divides into two or more daughter cells, this process is known as cell division. Cell division typically takes place as part of a lengthier cell cycle. Each parental cell produces two daughter cells, which are the means by which all cells multiply.
These freshly generated daughter cells may divide and grow, giving rise to a new cell population formed by the division and expansion of a single parental cell and its progeny.
In other words, repeated cycles of growth and division enable the formation of structures made up of millions of cells from a single cell.

According to the U.S. Department of Energy, a typical home in the United States uses approximately 900 kWh of electricity per month. On an annual basis, this is 900 kWh/month x 12 months/year = 10,800 kWh/year How many homes can a 500 MW power plant with a 0.9 capacity factor support? Begin by determining how much electricity the plant can provide per month: 1 MWh equals 1,000 kWh, so to convert MWh per month into kWh per month, we multiply by 1,000: So, On average, a 500 MW power plant can supply roughly 360 homes with electricity. a. During summer months, in hot regions of the United States, some homes run air conditioners continuously. How many homes can the same power plant support if average electricity usage increases to 1,200 kWh/month during summer months? Show your work.
Based on the energy generated by the power plant annually, the number of households the plant can support:
if energy usage is 10,800 kWh/year = 365000 householdsif energy usage is 24000 kWh/year = 164250 householdsWhat is electrical energy?Energy is energy that is due to movement of electrically charged particles.
Electrical energy is used in homes for many purposes.
Electrical energy is sold in units of kWh.
Data provided:
Capacity of power plant = 500 MW
Capacity factor = 0.9
Average annual household energy usage = 10,800 kWh/year
Energy generated in a year = 24 × 365 × 0.9 × 500 MW = 3,942,000 MWh/year
3,942,000 kWh/year = 3,942,000,000 kWh/year.
Number of households the power plant can support = 3,942,000,000 kWh/10800 = 365000 households
Number of households the power plant can support is 365000 households
If monthly electricity usage increases to 1,200 kWh
In a year, energy usage = 1200 × 12 = 24,000 kWh/ year
Number of households the plant can support = 3,942,000,000 kWh/24,000 = 164250 households
Therefore, based on the energy generated by the power plant annually, the number of households the plant can support:

Explanation:
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water known as a shelf sea.
FEATURES
1. They are broad, gently sloping plains covered by relatively shallow water.
2. They are usually covered with a layer of sand, silts, and silty muds.
3. Their surfaces exhibit some relief, featuring small hills and ridges that alternate with shallow depressions and valley like troughs.
A continental slope is an area of steep slope extending just after the continental shelf upto a considerable depth from where a gentle sea plain takes its form.
FEATURES
1. It has a relatively flat terraces and (under certain conditions) basins perched on the slope.
2. Continental slopes show a complex balance between erosional and depositional processes.
3. the sediments slough off and forms a continental slope.

Epithelial tissue is one of the four main types of body tissue found in your organs and covers internal and external surfaces in your body. It has several different structures and functions depending on where it is in your body.
Answer:
The epithelial tissues serves as a barrier and protection between internal cells and the dirt and microbes in the environment. It is what gives humans the ability to stretch, to move our fingers and arms in many positions.

Define apoptosis in biology
Answer:
Apoptosis is a form of programmed cell death that occurs in multicellular organisms.
Explanation:
Answer:
Apoptosis is the process of programmed cell death
Explanation:
Biochemical events lead to characteristic cell changes and death. These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, D.N.A. fragmentation, and mRNA decay. For example, those between the fingers of a developing hand. In adults, apoptosis is used to rid the body of cells that have been damaged beyond repair. Apoptosis also plays a role in preventing cancer. If apoptosis is for some reason prevented, it can lead to uncontrolled cell division and the subsequent development of a tumor.

Are there any parts of the human body that get oxygen directly from the air and not from the blood?
Answer:
The cornea in the eye.
Explanation:
The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is a transparent tissue, allowing for light to pass through. If it had blood vessels there, that would be an issue - for that tissue! And the cornea receives its oxygen directly from the air. When contact lenses were first used, people were instructed to take out their contacts when they go to sleep - because wearing them at night would reduce the oxygen intake to the eyes. Then they began manufacturing contact lenses that allowed for the lenses to “breathe” permitting people to wear them day and night.
