Answer:
Estradiol has a higher partition coefficient than H+ ions
Explanation
Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.

WILL MARK BRAINLIEST
A. Condensation of DNA
B. Crossing over
C. Pairing of chromosomes
D. Spindle formation
All of the following events occur during prophase in mitosis except crossing over (Option B)
Mitosis can be divided into four phases: prophase, metaphase, anaphase, and telophase.During prophase, the chromatids condense into chromosomes, thereby making them visible. The mitotic spindle is a structure composed of microtubule proteins that segregate the chromosomes in mitosis. This structure is formed in prophase.In Prophase homologous pairs of chromosomes are paired together. In metaphase, these chromosomes are lined up at the equator of the cell and sister chromatids are attached to the spindle fiber.Crossing over (or recombination) is the exchange of genetic material between non-sister chromatids that occurs during prophase I of meiosis.In conclusion, condensation of DNA, the pairing of chromosomes and, spindle formation occur during prophase, whereas crossing over occurs in prophase I of meiotic cell division (Option B).

In which layer of the atmosphere does the aurora borealis form? O A. The troposphere OB. The mesosphere O C. The thermosphere O D. The stratosphere SUBM
Answer:
The Thermosphere
Explanation:
Just took the test on A P E X, it's right. Hope this helps :)
Aurora Borealis forms in the thermosphere layer of the atmosphere. Therefore, option "C" is correct.
What are the different layers of the atmosphere?The atmosphere is made up of different layers which protect the life on Earth and make it habitable. There are four layers of the atmosphere troposphere, stratosphere, mesosphere, and thermosphere.
In the troposphere, the temperature rises from bottom to top. The ozone layer is present in the stratosphere. This is also known as the flying zone as no clouds are present in this layer. In the mesosphere, the air is much colder as there are gas molecules present that absorb solar radiation whereas the density of molecules in the thermosphere is very low.
The atmospheric layers protect the life on Earth.

How does the water on earth regulate the earth temperature
Answer:
It absorbs a lot of the sun’s energy.
Explanation:
A large portion of the sun’s energy and heat is absorbed by the oceans, which causes water to evaporate. Water has a high heat capacity, and therefore absorbs a large portion of the sun’s heat, regulating the earth’s temperature.

The chemicals made by organisms help to establish and maintain a uniform distribution pattern which makes the individuals space out evenly and prevents unwanted enemy.
What is Uniform distribution pattern?In a uniform distribution, the different individuals are equally spaced apart from each other, as seen in the negative allelopathy where various chemicals kill off the plants surrounding sages. In a random distribution, individuals which are spaced at unpredictable distances from each other, as seen among plants that have wind-dispersed seeds on them.
The chemicals synthesized by organisms help to establish and maintain a uniform distribution pattern because it makes individuals to space out evenly in the area and prevents unwanted enemy.

DNA undergoes the process of replication to produce new strands of identical DNA before cell divisions. Describe the basic dna replication. I will give you brainliest
Answer:
Please mark as Brainliest
Explanation:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication
Step 1 Replication Fork Formation. Before DNA can be replicated, the double stranded molecule must be unzipped into two single strands
Step 2 Primer Binding. The leading strand is the simplest to replicate
Step 3 Elongation
Step 4 Termination

APT and photovoltaic cells are simikar because
The question is incomplete, below is the complete question.
ATP and photovoltaic cells are similar because
A. they are both key components of plant cells.
B. they both produce chemical and electrical energy.
C. they are both key components of solar panels.
D. they both use energy from the sun to separate electrons from atoms.
The correct answer to the question is option D
ATP and photovoltaic cells are similar because THEY BOTH USE ENERGY FROM THE SUN TO SEPERATE ELECTIONS FROM ATOMS.
Photovoltaic cells are otherwise known as solar cells,they are made of silicone that are specially treated,these specially treated silicon transfers solar energy gotten from the sun to electrical energy.
These solar powered photovoltaic panels converts the rays from the sun into electricity.this it does by exciting electrons found in silicon cells and also using the photons of light from the sun.
When this electricity is generated,it can be used to supply energy that is renewable to ones home or business.
In ATP, during the process of photosynthesis, sunlight penetrates the cell and further pass into the chloroplast. This light energy is further intercepted by granal stacks containing chlorophyll molecules, from then,some of those light energy are concerted to chemical energy,as this is going on,a phosphate is then added to a molecule to give rise to ATP.
