Answers

Intermediate disturbance

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.

Thus, the correct option is A.

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

Answers

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.

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

Answers

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.

Answers

Answer:

Which of the following would require an input of energy? Question 5 options: a)  diffusion b)  filtration c)  osmosis d)  vesicular transport

Explanation:

vesicular transport

Vesicular transport is the process that would require an input of energy.

Vesicle-mediated transport is the transport process that involves vesicles or vacuoles that form from or fuse with the cell membrane.

Transport vesicles interact indirectly with microtubules through proteins that have the ability to move and are known as dyneins and kinesins. These proteins transform the energy of ATP into movement in a certain direction.

The transport vesicles use microtubules to travel directly and quickly to their destination.

It can be done in two parts:

Exocytosis: when a vesicle reaches the cell surface, its membrane fuses with the cytoplasmic membrane and expels its contents to the outside.

Endocytosis: the material that will be incorporated into the cell induces an invagination of the membrane, producing a vesicle that encloses the substance.

Therefore, we can conclude that vesicular transport is the process that would require energy which is obtained from the transformation of ATP.
