The diagram above represents the phases of the moon. Position 1 represents the
new moon. Positions 2 through 8 represent the phases of the moon that follow.
Which phase does position 8 represent?
Answer:
waxing crescent
Explanation:
Position 8 represents waxing crescent phase. It is observed after a new moon and can be observed until the first quarter of moon.
What are the phases of moon?The waxing and waning nature of the moon is responsible for its various phases. This is due to the fact that moon is the only natural satellite of the earth. It revolves around the earth in a fixed orbit.
As earth revolves around the sun, the sunlight that falls on moon makes us visble those parts. Thus, it appears that moon is changing its shape.
A lunar month which is of 29.5 days usually is contains four primary and four intermediate phases. It is described as: New moon, Waxing crescent moon, First quarter, Waxing gibbous moon, Full moon, Waning gibbous, Last quarter and Waning crescent moon.
These phases have specific time in which they can be observed in the sky. New moon is an exception, as no part of the moon is visible then.
The phases of the moon are therefore considered as astronomically important.

what is a warm air mass that rises over a cold air mass?
Answer: warm front
Explanation: When a warm air mass meets a cold air mass, the warm air rises since it is lighter. At high altitude it cools, and the water vapor it contains condenses. This type of front is called a warm front. It generates nimbostratus clouds, which can result in moderate rain.

Explain how stem cell therapy helped Lucy break down deoxyadenosine
Answer:
It helped her fight off the stop protein, eventually helping her create more amino acids.
The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.
What is amino acid?Amino acid has the organic compound containing both an amino[tex](-NH2)[/tex] and a carboxylic acid [tex](-COOH)[/tex] functional group. The component of amino acid not contained in starch is that amino acids contain nitrogen but not starch.
On the other hand, starch has a carbohydrate molecule made up of monomers called monosaccharides. The monosaccharide is a long chain of carbon, hydrogen and oxygen atoms. This suggests that the major structural difference between amino acids and starch has that amino acids contain nitrogen but not starch.
There are several types of protein such as structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.
Therefore, The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.

Explanation:
1. How does the cell membrane allow animals to move without rupturing the cells in the body?
2. How does a cell membrane allow some molecules to pass right through the membrane?
3. Why is it important the some molecules (oxygen and carbon dioxide) be allowed to pass through the cell membrane without the use of a transport system?
4. How does the cell membrane allow the cell to reproduce into two separate cells?
5. In the lab, small bubbles would merge with the larger bubbles. How does this property of cell membranes demonstrate how a vesicle can transport substances from one organelle to another?
6. Cells require molecules that cannot simply pass through the cell membrane. Explain how the cell can use proteins to transport these molecules across the cell membrane.
.
Explanation:
1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.
2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.
3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .
4) during fission a copy of the DNA is made and attached to the cell membrane as well. As this cell elongate in preparation for fission, the two DNA copies are pulled apart two opposite ends of the cell. New membrane material is deposited between the two ends of the cell, and a new wall grows between them .
5) UMASS STEM-ED From Bubbles to Cell Membranes Workshop. Bubble ... dynamic nature which can't be properly appreciated in a static textbook. ... the small thread through one of the straws.

PLS HELP, Why is gene flow important to the overall health of a species?
Answer:
Gene flow is an important mechanism for transferring genetic diversity among populations. ... Gene flow is expected to be lower in species that have low dispersal or mobility, that occur in fragmented habitats, where there are long distances between populations, and when there are small population sizes.

Because it is important for transferring genetic diversity among populations. Even low levels of gene flow can have a large impact, counteracting the other evolutionary force.
