Question 9
How do animals get nitrogen that is stored in the soil?
O A) Animals do not take in the nitrogen stored in the soil.
O B) Bacteria change the nitrogen into a gas that the animals breathe.
OC) Plants ab orb the nitrogen from the soil and animals can eat the plants.
O D) The animals can eat the soil and absorb the nitrogen through their digestive system.
Answer:
the answer is C
Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use

Answer:
This question is asking to fill the blank spaces. The answers are:
1. Capsid
2. Cell content
Explanation:
A virus is an organism that is incapable of reproducing itself without invading an host cell. It is generally made up of a genetic material (DNA or RNA), and a protein coat called capsid. This CAPSID is the part of the virus that protects its genetic material and content.
This function of capsids is similar to that of the cell membrane in prokaryotic and eukaryotic cells as they both function to protect the cellular content including the genetic material.
Do you think an Ecologist would classify nutrients as living things or nonliving things? Explain why. Please help this is a school assignment I will mark brainlliest for first answer.
(This is 7th grade science).
they would classify it as non living
Explanation:
My proof is I'm in 8th grade
Answer:
An Ecologist would classify nutrients as non-living things. Living things require water, food, shelter, and most important of all, nutrients that are essential to their diet to survive. For this reason I believe they would be classified as non-living, since nutrients don't need these things to survive and provide health to things that are alive.
Galactosemia is an inherited disorder in humans. A person with the disorder cannot digest the sugars in milk. The allele for normal digestion (G) is dominant; the allele for galactosemia (g) is recessive. A female who is heterozygous for the galactosemia trait and a male who has galactosemia have a child. In your response, be sure to: Identify the genotypes of the mother and father
Answer:
This question is incomplete, the remaining part of the question is:
" Explain how this disorder can be passed on in the family. In your response, be sure to: Identify the genotypes of the mother and father"
Please find the explanation below
Explanation:
According to this question, the Galactosemia trait is an inherited disorder in humans that causes inability to digest the sugars in milk. The allele for normal gene (G) is dominant over the allele for galactosemia (g). This means that a heterozygous human (Gg) will not be normal (no galactosemia).
In this family, female who is heterozygous for the galactosemia trait (Gg) and a male who has galactosemia (gg) have a child. Note that each parent will produce gametes as follows:
Gg - G and g gametes
gg - only "g" gametes
To inherit this disorder or for the parents to pass on this disorder to their child (children), they have to both contribute the allele for galactosemia (g) in their gametes to produce a child that has two galactosemia alleles in his/her genotype i.e. gg
This means that in this cross (see attached image), the probability of their child to have the disorder is 1/2 or 50% while the probability of having a normal child is also 1/2 or 50%.
(Urgent!) Explain how laundry detergent can be a product of biotechnology.
Answer:
Another important class of compounds produced by biotechnology is enzymes. One of the most significant commercial enzymes of this type is subtilisin, which is produced by a bacterium because many stains contain proteins, the manufacturers of laundry detergents include subtilisin in their product.
Explanation:
(please mark me brainliest if you can)
Answer:
Explanation:
Most biological laundry detergents contain lipase and protease enzymes, both of which are found in the body. Lipases break down fats and oils, while proteases work to break down protein chains. Their ability to break down these compounds makes them excellent for stain removal.
Compare and contrast evaporation and convention and how the processes move water through the water cycle
Answer:
Evaporation and convection are both heat transfer processes that transfers heat from hotter to colder regions. Evaporation however involves a change of state of the molecules whereas convection does not, rather occurs due to difference in densities of the molecules.
In the water cycle, both evaporation and convection work to lift liquid water from the earth's surface into the atmosphere where they condense into water vapor and eventually fall as rain.
Explanation:
Evaporation is a process by which a liquid turns into vapor when it absorbs heat.
Convection is the process of heat transfer by the actual movement of the heated molecules from one region to another.
Comparison:
Both processes involves transfer of heat
Both processes involves movement of molecules
Contrast:
Evaporation involves a change of state of the molecules, whereas convection does not.
Evaporation is a surface phenomenon whereas convection occurs throughout the whole fluid in cycles
Evaporation results takes heat away from a body whereas convection transfers heat to a body
In the water cycle, when the heat from the sun heats up the earth's and water surfaces, the water molecules absorb heat and turn to water vapor by the process of evaporation. The water vapor rises into the atmosphere.
During convection in the water cycle, heated air near the earth's surface rises as it becomes less dense than cold air and carries along water vapor with it into the atmosphere. As the hot air water vapor mixture rises, it becomes cold and condenses into water vapor which later falls as rain.

if something needed to enter the cell and couldn't go through the phospholipid bilayer, how else could it enter the cell?
Answer:
Through facilitated diffusion
Explanation:
A molecule that finds it difficult to enter through the cell membrane's phospholipid bilyaer can be assisted in doing so through a process known as facilitated diffusion.
Ordinary diffusion will not permit the movement of molecules against a concentration gradient or molecules can be prevented from passing the phospholipid bilayer due to their sizes/charges. Within the phospholipid bilayer exists special passages lined with carrier or channel proteins.
These proteins facilitate some molecules that will ordinarily not pass through the bilayer to pass through their special passages. This process is referred to as facilitated diffusion.
Relate the surface area of a cell to the transport of materials.
If the size of a cell increases it will be more difficult (all other things being equal) for diffusion to transport materials out of the cell. Therefore, less of the cell's interior will be able to come in contact with the cell's surface. If less of it comes in contact, less of it can cross the cell membrane.

A ____ surface will absorb all colors.
A green surface will absorb all colors and reflect ____
Answer:
A Black surface will absorb all colors.
A green surface will absorb all colors and reflect green.
=> Any surface which absorbs all the colors appear to be black because no color is reflected.
=> A surface color is a color which is reflected by it.
For example:
If a surface is red colored, This means that it reflects red color. That's why it appears to be red.

Describe the Cell Cycle [Interphase, G1 phase, S phase, G2 phase]
describe them all please :)
G1, S and G2 phases are all cumulatively referred to as interphase involving the growth of a cell and the replication of its DNA. Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents. The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. The S phase only begins when the cell has passed the G1 checkpoint and has grown enough to contain double the DNA. S phase is halted by a protein called p16 until this happens.
Which describes one thing that happens during thermoregulation when a sensor
recognizes that a person's temperature is 39 degrees C?
1. The muscles in the body expand and contract quickly, producing friction.
2. Blood vessels under the skin expand.
3. Sweat glands are "shut off."
4. Muscles under the skin make body hair stand on end.
Answer:
Muscles under the skin make body hair stand on end.
Explanation:
The body needs to keep its temperature around a set point of about 37 degrees Celsius.
Muscles under the skin make body hair stand on end happens during the thermoregulation.
What do you mean by thermoregulation?Thermoregulation is a mechanism by which mammals maintain body temperature with tightly controlled self-regulation independent of external temperatures. Temperature regulation is a type of homeostasis and a means of preserving a stable internal temperature in order to survive.
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different.
Thermoregulation is controlled by the hypothalamus, which is a small structure in your brain. If the hypothalamus senses your body's temperature is too high or low, it sends signals to your nervous system.
