Answer:
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle.
Explanation:
Identify and construct an explanation of the main disadvantage of growing a potato crop with few variations. What could be an unwanted effect?
The main disadvantage of growing a potato crop with few variations may be the loss of yield in a changing environment. It is a consequence of artificial selection.
What is artificial selection?Artificial selection refers to the mating process made for humans in order to select crops and animals' progeny with desired traits.
The main subject of concern in artificial selection is the loss of valuable genetic variability.
In this case, artificial selection may lead to the potato crops being unresponsive to challenging environments.

When we look at reproduction too they are similar. They both produce gametes that fuse to form a zygote. They both have DNA that replicates to produce copies of itself.
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.
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.
how to calculate the concentration of starch in a solution
Answer:
From the linear regression analysis of y=4.8811x+0.1453 we calculate the starch concentration by rearranging the formula to x=(y- 0.1453)/4.8811.
Explanation:
The starch concentration of the sample is 0.159 mg/mL. The dilution factor was 1:10 making it a concentration of 1.59 mg/mL. For each cuvette concentration calculation, multiply the concentration of the diluted starch solution in the Erlenmeyer flask by the volume of the diluted starch solution you added to the cuvette. Then, divide by the total volume of liquid you placed in the cuvette, which is 5 mL.

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:
Neuronal cells that are short-lived and are frequently replaced are retinal cells. nociceptors. Pacinian corpuscles. gustatory receptors. olfactory sensory neurons.
The neuronal cells that are short-lived and are frequently replaced are called the olfactory sensory receptors.
Neuronal cell regenerationNeuronal cells, which is also called neurons, are the cells of the nervous system that aid in the transmission of electrical information from one cell to another.
Olfactory sensory neurons are bipolar nerves that are activated when airborne molecules in inspired air bind to olfactory receptors expressed on their cilia.
They are usually short-lived and are regenerated because they are constantly exposed to environmental agents.
Therefore, neuronal cells that are short-lived and are frequently replaced are called the olfactory sensory receptors.

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.
