Weathering is a process of disintegration of the rock by atmospheric exposure. Repeated and frequent freeze and thaw cycles of water cause ice wedging. Thus, option D is correct.
What is mechanical weathering?Weathering can be physical, mechanical, or chemical. Mechanical weathering involves the erosion or the disintegration of the parent larger rocks into smaller sediments of the small rocks. It involves either solidified or liquid water as a key agent to deteriorate the rock.
Ice wedging is a mechanical weathering that involves seeping and falling of the cold water or precipitation over an area that repetitively and frequently gets frozen and thawed over and again.
This water gets deposited and causes wedges to form in the parent rock. The cracks are formed that erode and disintegrate the rocks into smaller pieces.
Therefore, option D. ice wedge is formed by mechanical weathering.

Explanation:
There are no known motor proteins that move on intermediate filaments (IFs).
What property of intermediate filaments would most likely explain the lack of motor proteins?
a) Tissue specific expression of IFs prevent a single type of motor protein to evolve over time.
b) Lateral bundling of IFs prevent motor movement.
c) IFs do not bind a nucleotide.
d) IFs are less dynamic than microtubules and actin filaments.
e) IFs are unpolarized.
Answer: The correct option is E ( Intermediate filaments are unpolarized).
Explanation:
Intermediate Filaments are usually associated with cells that can withstand mechanical stress which includes claws of animals, hair and makes up the dead remnants of the epidermal cell of the skin. Therefore without the supporting network of intermediate filaments, an epithelium remains intact but the cells are prone to damage by abrasive forces.
Intermediate filaments are so named because they are thicker than actin filaments and thinner than microtubules or muscle myosin filaments
The properties or characteristics of an intermediate filaments that explains the lack of motor proteins is as a result of its subunits which are elongated, not globular and are associated in an anti-polar manner. Therefore, the overall filament has no polarity, and therefore no motor proteins move along intermediate filaments
Describe the effect that increasing the potassium ions initially had on the heart in this activity. Relate this to the resting membrane potential of the cardiac muscle cell. How well did the results compare with your prediction?
Answer:
When there is an increase in potassium within the cell, depolarization is generated
Explanation:
Depolarization is the intracellular increase of potassium in the cardiac cell, this is how the resting potential is reached, this state of the cell refers to the fact that the cell does not execute or transmit any signal, it is in a refractory state of signals, since it does not capture any, this is how it prepares and recovers for future action potential.

Leukopenia is a condition characterized by a decrease in white blood cells. What effect does leukopenia have on the body's ability to fight infection?
Leukopenia increases the body's ability to fight infection.
Leukopenia decreases the body's ability to fight infection.
Leukopenia has no effect on the body's ability to fight infection.
Leukopenia increases the body's ability to fight infection at certain times and decreases it at other times.
Answer:
Leukopenia decreases the body ability to fight infection
Explanation:
There are three major types of cells in the blood namely: platelets, red blood cells (erythrocytes) and white blood cells (leucocytes). These cells perform individual functions in the blood tissue, however, the cell saddled with the responsibility of fighting against foreign bodies and preventing the body against infection is the WHITE BLOOD CELL (LEUCOCYTES).
According to this question, Leukopenia is a condition characterized by a decrease in the number of white blood cells in the blood. The effect of this decrease in number of white blood cells caused by Leukopenia is a DECREASE IN THE BODY ABILITY TO FIGHT INFECTION.

Which mRNA modification is likely absent if the mRNA is degrading prematurely from the 5 end of the mRNA?1) splicing together of exons.2) addition of the 3' polyadenylated tail.3) addition of the 7-methylguanosine cap to the 5 end.4) RNA editing.5) removal of introns.
Answer:
3) addition of the 7-methylguanosine cap to the 5 end
Explanation:
The 7-methylguanosine (m7G) cap is a modified methylated version of the Guanosine (G) nucleotide which is located on the 5′-terminus of the eukaryotic messenger RNA (mRNA). The m7G cap plays a key role in mRNA translation in eukaryotic organisms, from yeasts to mammals. During mRNA processing, m7G cap is added at the 5' end in order to protect mRNA from degradation by nuclease enzymes. Moreover, this cap also enables the proper attachment of the mRNA molecule to the ribosome during protein synthesis.

Suppose that a mouse with black fur has both an allele for black fur and an allele for white fur (Bb). Based on this information, you can conclude that the dominant allele must be for fur andthe recessive allele must be for fur.
Answer:
Dominant black fur and recessive white fur
Explanation:
Black fur is showing over white fur so it is a dominant trait and white is recessive
Answer:
The dominant must be for the black fur and the recessive must be for the white fur.
Explanation:
A variation of a gene, which will generate a certain phenotype, even in the existence of other alleles is known as a dominant allele. On the other hand, a version of a gene that needs to be when inherited in order to be articulated in the phenotype is known as a recessive allele. The offspring will not express the phenotype of the recessive allele if it is inherited together with a dominant allele, that is, the phenotype of the dominant allele will just be expressed.
