what does it mean when an emission line of helium from a galaxy is shifted toward red
A. The galaxy contains a small percent of Hydrogen
B. The Galaxy is moving toward the viewer
C. The galaxy is moving away from the viewer
D. The galaxy contains a large percent of hydrogen
Answer:
the answer is the galaxy is moving away from the viewer! lemme know if you need the rest of the answers or anymore help
Explanation:
i took the test :)
When an emission line of helium from a galaxy is shifted toward red, it means that the galaxy is moving away from the viewer. Thus, the correct option is C.
What is Galaxy?The Galaxy may be defined as a tremendous collection of dust, gas, dark matter, and billions of stars and their solar systems, all held together by gravity.
When it is shifted toward red, it describes the displacement of an emission line of helium from a galaxy to longer wavelengths. This alteration is interpreted as a doppler shift.
It depends on the location of any celestial body in a galaxy. The farther from us a star is, the more its light has shifted towards the red end of the visible spectrum.
Therefore, when an emission line of helium from a galaxy is shifted toward red, it means that the galaxy is moving away from the viewer. Thus, the correct option is C.

Answer:
Distance=Speed×time
=300000×8.5 (1 minute= 60seconds)
Therefore 8.5×60=510seconds

Simon is comparing the communities of living things that live in two bodies of water a long river, and the ocean bay just beyond the mouth of the river.
Comparing which of these abiotic factors would be most useful for Simon to explain the differences in the communities? Assume that the water is
unaffected by pollution
A
the salinity of the water
O
B В.
the volume of water in each ecosystem
C. the rate of evaporation of the water
D
the sediments that are deposited on the river bottom or ocean floor
Review progress
The abiotic factor that would be most useful for Simon to explain the differences in the communities would be A) the salinity of the water. Salinity refers to the salt concentration in the water, and it can have a significant impact on the types of organisms that can live in the water.
What are abiotic factors?Abiotic factors are the non-living components of an ecosystem, including physical and chemical factors such as temperature, sunlight, water, soil composition, air, and nutrients. These factors can significantly affect the living organisms and communities within an ecosystem.
The ocean bay is likely to have a higher salinity than the river because of its connection to the open ocean. Therefore, the types of organisms that live in the ocean bay may be better adapted to higher salinity levels, while the river may support a different community of organisms that are adapted to lower salinity levels.
The other factors listed (volume of water, rate of evaporation, and sediments) may also impact the communities of living things in the two bodies of water, but salinity is likely to be the most significant factor.

During receptor mediated endocytosis, in order for a vesicle to bud from the membrane, the vesicle must have outer coat made of _____ protein, which is secured to the vesicle membrane with the help of the protein _________. g
Answer:
Clathrin and Adaptin.
Explanation:
The outer coat is Clathrin and is secured through help of Adaptin in receptor mediated endocytosis.
(Brainliest Answer please!!!!)
During receptor mediated endocytosis, in order for a vesicle to bud from the membrane, the vesicle must have outer coat made of CLATHERIN protein, which is secured to the vesicle membrane with the help of the protein ADAPTIN.
What is receptor mediated endocytosis?Receptor-mediated endocytosis is a type of endocytosis in which a specific target molecule is captured by receptor proteins on the cell surface. The receptors, which are transmembrane proteins, aggregate in covered pits on the plasma membrane. The name stems from a covering of proteins on the cytoplasmic side of the pit known as coat proteins. Clathrin is the best-studied coat protein.Adaptins are a category of membrane proteins that mediate the interaction of transmembrane proteins with the clathrin protiens.Endocytosis is induced when receptors bind to their specific target molecules, and the receptors and their attached molecules are transported into the cell in vesicles. The coat proteins aid in this process by giving the vesicle its rounded form and assisting in its separation from the membrane.Hence, Clathrin and Adaptin are the two coat proteins involved in receptor mediated endocytosis. the same is shown in the diagram provided below.

When glycogen is formed from monosaccharides, it occurs by a process called hydrolysis.
True
False
Answer:
yes its true. it occurs by a process called hydrolysis
The formation of glycogen from monosaccharides happens through the process of dehydration. So the statement is false.
What is the process of glycogen formation?
The process of formation of glycogen is called glycogenesis. Glycogen is the storage form of glucose, a primary carbohydrate in the liver and the muscle cells of animals
The process of Glycogenesis happens when the levels of glucose in the blood are high enough to allow the excess glucose to be stored.
The process of glycogenesis is stimulated by the insulin hormone. It helps the muscle cells to uptake glucose into themselves. Insulin is not required for the transport of glucose into the liver cells.
However, insulin has very important effects on the metabolism of glucose inside the liver cells. Insulates stimulates the process of glycogenesis and inhibit the process of glycogenolysis, which is the breakdown of glycogen into glucose.
Therefore the statement is false.

which model would you use to examine the relationship between nitrogen concentration and plant growth
Linear regression
Species area curve
Intermediate disturbance
Hamilton’s Rule
Linear regression is used to examine the relationship between nitrogen concentration and plant growth. The correct option is A.
What is linear regression?When modelling the relationship between a scalar answer and one or more explanatory variables in statistics, linear regression is a linear method.
Simple linear regression is used when there is only one explanatory variable, and multiple linear regression is used when there are numerous variables.
The processes that underlie the experimentally based nitrogen productivity hypothesis can be investigated using model equations.
It depicts a linear relationship between relative growth rate and plant nitrogen concentration and has a negative intercept at a nitrogen concentration of zero, is consistent with this theory.
