What process moves energy from Earth's surface to high in the troposphere?
a. solar energy
b. conduction
C. convection
d. the nitrogen cycle
Answer:
Explanation:
Energy is transferred between the Earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. The rate of energy transfer by conduction is higher when there is a large temperature difference between the substances that are in contact.

What statement describes the process of solar nuclear fusion?
A. Hydrogen molecules are fused together and become hydrogen molecules, giving off large amounts of energy
B. Hydrogen molecules are fused together and become oxygen molecules, giving off large amounts of energy.
C. Hydrogen atoms are fused into deuterium, then helium -4, then back into hydrogen, each step giving off large amounts of energy
D. Hydrogen atoms are fused into deuterium, then helium -3, then helium-4, each step giving off large amounts of energy
Answer:
B
Explanation:
Fusing both molecules would create a blast of energy not even the atoms can withstand so they explode but implode at the same time.

Describe what hereditary is and how it works in mice
Answer:
Heredity is the inheritance of genes from parent "mice" to their offspring. ... mice have 20 SETS of chromosomes, making 40 chromosomes overall. Each chromosome may not have the same form of allele as the next, since one pair came from the mother and onother the father.
Explanation:
A student claims that electronegativity is not related to the
concept of polarity. Use water as an example to provide
reasoning to refute the student's claim.
PLEASE HELP!
Answer:
Please find the explanation below
Explanation:
Polarity of a molecule is the function of the difference between the electric charges of two atoms that make up the molecule. This polar nature is greatly influenced by the ELECTRONEGATIVITY, which is the ability to attract electrons, of the atoms involved. For example, using water molecule, H2O, as a case study.
Water is known to be a highly polar molecule due to the electronegativity values of the atoms that make up its molecule. Oxygen atom is a more electronegative atom than hydrogen, hence, it pulls more electrons towards itself, leaving the hydrogen atom more electropositive. This forms the difference in the electrostatic force between oxygen and hydrogen, making water POLAR.
HENCE, the student is wrong to have said electronegativity is not related to the concept of polarity.

What likely determines the phenotype of a given cell?
—
Which genes are expressed in that particular cell
How often that cell undergoes mitosis
How often a cell is used for a given biological function
No answer text provided.
Answer:
Which genes are expressed in that particular cell
Explanation:
Not all genes are expressed at the same time. Distinct gene expression patterns define the identity of each cell.
For example, the genes involved in the function of muscle tissues are only expressed in muscle cells, not in skin cells (and vice versa).
Therefore, the phenotype of the cell is largely determined by the activity of genes in the cell

Based on Figure 1, which of the following statements best describes the epinephrine signaling pathway?
Group of answer choices
It involves the opening and closing of ion channels.
In involves enzymes activating other enzymes.
It involves changes in the expression of target genes.
It involves protons moving down a concentration gradient.
Answer:
It involves enzymes activating other enzymes.
Explanation:
Epinephrine activates glycolysis (i.e., glycogen breakdown) in skeletal muscle and at a lower level in the liver, which is more responsive to glucagon. When epinephrine binds to a G protein-coupled receptor, the receptor changes its conformation and then triggers a molecular cascade that involves the production of cyclic adenosine monophosphate (cAMP), a well known second messenger molecule in signal transduction pathways. Moreover, the beta-2 adrenergic receptor (ADRB2) is a G-protein-coupled receptor known to activate adenylate cyclase enzyme that leads to appropriate increases in cAMP and activation of protein kinase A (PKA).
Based on Figure 1, the statement that best describes the epinephrine signaling pathway is:
B. It involves enzymes activating other enzymes.
Epinephrine signaling pathway occurs when the neurotransmitters in the body helps the hormones to communicate with the epinephrine.
When this happens, there is a reaction within the receptor, causing it to become active.
As a result of this, there is a binding with the G-protein receptor which releases the cyclic adenosine monophosphate (cAMP).
This in turn, activates the other enzymes.
Therefore, the correct answer is option B

Which statement describes photosynthesis?
a. Carbon dioxide and water combine to form glucose and oxygen.
b. Carbon dioxide and glucose combine to produce energy and water.
c. Carbon dioxide, glucose, and water are released to produce energy.
d. Carbon dioxide and water are released when glucose and oxygen combine.
Answer:
Your answer is A). In the presence of sunlight, plants take in the CO2 that we breathe out, and absorb water from the ground to make glucose (which the plant will use for energy when the sun isn't out), and oxygen which we breathe in again.
