which of these is an agent of wedging

Answers

Final answer:

An agent of wedging may be water in frost wedging, plant roots in root wedging, and salt crystals in the case of salt crystal growth. These agents contribute to the physical weathering process known as 'wedging.'

Explanation:

An agent of wedging refers to a factor that contributes to the physical weathering process called 'wedging.' There are several types of wedging, including freeze-thaw or frost wedging, root wedging, and salt crystal growth. In the case of frost wedging, the agent is water. Water seeps into crevices and when it freezes, it expands, creating wedging force. In the case of root wedging, the roots of plants can serve as the agent, growing into fractures and exerting pressure. For salt crystal growth, the salts left behind by evaporated water can act as the wedging agent, growing and exerting a force that can break apart the rock.

A certain species of rabbit can have either black or grey fur. The allele for black fur is dominant over the allele for grey fur. If a homozygous black rabbit is crossed with a heterozygous black rabbit, what phenotypic ratio will occur in the first generation?

A.
50% black : 50% grey
B.
25% black : 75% grey
C.
100% black : 0% grey
D.
75% black : 25% grey

Answers

The phenotypic ratio that will occur in the first generation would be 100% black.

Assuming that the black fur allele is represented by B and the grey by b allele, the homzygous black rabbit's genotype will be BB while heterozygous black will be Bb.

Crossing BB with bb:

                     BB     x     Bb

                  BB   Bb   BB   Bb

Since B and dominant over b:

First generation:

1/2 BB - Black

1/2 Bb - Black

Thus, the phenotypic ratio in the first generation would be 100% black.

More on phenotypic ratios can be found here: https://brainly.com/question/3840678?referrer=searchResults

Final answer:

The phenotypic ratio for the cross between a homozygous black rabbit and a heterozygous black rabbit will be 100% black due to the dominance of the black fur allele, resulting in no possibility for grey fur in the first generation.

Explanation:

The question is regarding the phenotypic ratio of the offspring when a homozygous black rabbit (with the dominant allele for black fur) is crossed with a heterozygous black rabbit. Considering the dominant allele for black fur is represented by 'B' and the recessive allele for grey fur is represented by 'b', a homozygous black rabbit would have the genotype 'BB', and a heterozygous black rabbit would have the genotype 'Bb'.

The possible combinations of their offspring's genotypes can be determined using a Punnett square. The homozygous parent can only contribute a 'B' allele, and the heterozygous parent can contribute either a 'B' or 'b' allele. Thus, the potential genotypes of the offspring would be 'BB' or 'Bb'. Since both 'BB' and 'Bb' result in black fur due to the dominance of the black fur allele, all the offspring will have black fur.

The resulting phenotypic ratio will be 100% black fur to 0% grey fur because no 'bb' genotype can result from this cross. Therefore, the correct answer is C. 100% black : 0% grey.

How is the structure of a unicellular organism different from the structure of a multicellular organism? How does this difference affect cellular function in each organism?

Answers

A unicellular organism has only one cell while a multicellular organism is made of many cells working together. The consequence is that in unicellular organisms, the single cell has to take care of every function while in multicellular organisms, the cells can divide up the work and each cell take care of only one function, but perform that function really well.

Final answer:

Unicellular organisms are made up of a single cell, while multicellular organisms are made up of multiple cells with different shapes and organized arrangements called tissues and organs. This difference affects cellular function in each organism.

Explanation:

Unicellular organisms are made up of a single cell, while multicellular organisms are made up of multiple cells with different shapes and organized arrangements called tissues and organs. This difference affects cellular function in each organism. In unicellular organisms, the single cell performs all the necessary functions for survival, including obtaining nutrients, reproducing, and eliminating waste. In multicellular organisms, cells specialize in specific functions such as digestion, respiration, and movement, which allows the organism as a whole to perform more complex tasks and have increased efficiency.

which type of macromolecules regulates cell processes or transport material into and out of the cell

Answers

Final answer:

Proteins are the type of macromolecules that regulate cell processes and transport materials into and out of the cell, and they do so via various mechanisms such as channels, carriers, pumps, or through vesicle transport like endocytosis and exocytosis.

Explanation:Types of Macromolecules Regulating Cell Processes

Among the four major classes of biological macromolecules—carbohydrates, lipids, proteins, and nucleic acids—proteins are crucial regulators of cell processes and are responsible for the transport of materials into and out of the cell. Proteins may be involved in transport, functioning as channels, carriers, or pumps in the plasma membrane to facilitate the movement of substances across the cell membrane. They may also act as enzymes or signaling molecules, helping to regulate cellular pathways and responses. For the transport of larger macromolecules, cells utilize vesicle transport mechanisms like endocytosis and exocytosis. These processes involve the formation of vesicles to enclose the substances to be transported, requiring energy in the form of ATP to move these vesicles to and from the cell membrane.

Understanding the Role of Proteins

Proteins are synthesized by the cell's ribosomes and take on a diverse range of functions due to their varied structures, which are dictated by the sequence of amino acids they contain. This versatility in structure allows proteins to function as key components in various cellular activities, including those that regulate cellular functions or mediate the transport of substances into and out of cells. To sum up, proteins are the type of macromolecules that primarily regulate cell processes or transport material into and out of the cell.

Final answer:

Proteins are the macromolecules that regulate cell processes and facilitate the transport of materials into and out of the cell. They are involved in various cellular roles including transport and are essential for vesicle transport mechanisms such as endocytosis and exocytosis.

Explanation:

The macromolecules responsible for regulating cell processes and material transport into and out of the cell are known as proteins. These biological macromolecules are essential for life and are made from smaller organic molecules. In the context of cellular functions, proteins can have structural, regulatory, contractile, or protective roles. They can also serve in transport, be a part of storage mechanisms or cell membranes, act as toxins or function as enzymes. Each cell contains thousands of different proteins, each with a unique function tailored to the needs of the cell.

For the active transport of macromolecules across the plasma membrane, cells employ processes known as vesicle transport, which includes endocytosis and exocytosis. Both of these processes require energy to move substances into or out of the cell within vesicles. The transport and function of proteins as well as the utilization of energy for these processes are necessary for the cell's proper functioning and contribute significantly to the cell's structural components.

As a result of climate change Earth's temperature is rising and sea ice is melting what is a likely effect

Answers

The animals who live in that area will become endangered because their habitat is being heated and they are made for cold only

As a result of global warming, the average surface temperature of Earth is increasing and the sea ice (in the polar regions) is melting, which in turn is effecting the oceans, animals, plants and ecosystems, agriculture, etc.

The Earth's temperature has increased by 1.4 degrees Fahrenheit over a century and is causing the ice to melt in the polar regions. This melting of ice is causing the sea levels to rise which means more heat is absorbed by the water, thus increasing the temperature of the oceans.

These changes in the temperature are making it difficult for many species to survive and some of the animals and plants have already started moving to higher altitudes as a result of this.

Insertion into the RER membrane is cotranslational for TMPs, why is this necessary?

Answers

Answer:

Transmembrane  are inserted into the rough endoplasmic reticulum membrane  while they are still in their synthesis stage. They make there way to ER  with the help of the signal sequence already present in the synthesizing protein. The signal sequence stops the process of translation and directs the ribosome, carrying the unfinished protein to dock with ER.Translation than restarts when the signal sequence dock with the ER and it occurs in the ER membrane. This process is necessary because it allows the passage of transfer of protein to cross the lipid bilayer,  ER lumen facilitate protein folding and it rectifies the aberrant proteins and target them towards cytosol for destruction.

Answers

cold winter climate

An abiotic factor that contributed to the evaluation of this set of behaviors is a cold winter climate. Thus, the correct option is D.

What is Habitat?

Habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. In other words, it may be defined as the area where the basic demands of an organism are fulfilled such as food, space, and mating partner.

It is the only reason that due to the cold winter climate, many birds will collect seeds and then hide them in various caches throughout their habitat in the autumn season itself.

This is because, in a cold winter climate, it is really tough for birds to find food and store it safely away from predators.

Therefore, an abiotic factor that contributed to the evaluation of this set of behaviors is a cold winter climate. Thus, the correct option is D.
