the elongation of the leading strand during dna synthesis
Answer:
Depends on the action of DNA Polymerase
Explanation:
The ribosome continues to translate each codon in turn throughout the elongation phase. A bond known as a peptide bond is used to connect each relevant amino acid to the expanding chain. Up until all the codons are read, elongation continues.
What leading strand during DNA synthesis?The two strands that make up DNA are the leading, continuous strand, which moves toward the replication fork, and the trailing, discontinuous strand, which moves away from the replication fork.
A process known as elongation occurs when more nucleotides are inserted, lengthening the RNA strand. RNA polymerase “walks” along one strand of DNA, called the template strand, during elongation in the 3' to 5' direction.
Therefore, DNA polymerase III catalyses the elongation of DNA by attaching incoming DNA to the 3' end of the elongated DNA.

which graphic organizer best compares the energy inputs and outputs of cellular respiration and photosynthesis?
Answer:
glucose and oxygen is used for the input cellular respiration while carbon dioxide and water is used for output cellular respiration
Light energy → photosynthesis → chemical energy → cellular respiration → chemical energy is the best compares the energy inputs and outputs of cellular respiration and photosynthesis.
Thus option B is correct.
What do you mean by energy transfer ?In a living cell the energy can only transfers from one cellular reaction to another by changing its form from one type of energy to another.
photosynthesis and cellular respiration are two closely related opposite cellular reaction.
In photosynthesis light energy from sun can be absorbed by chlorophyll pigment, then conversion of inorganic matters to organic matter.
It stores energy in the form of chemical energy called glucose.
In cellular respiration, products of photosynthesis that is glucose and oxygen converted in the carbon dioxide and water with release of ATP stores a high amount of energy.
Thus option B is correct.

Contraction of the left scalene muscles tilts the head toward the left shoulder. What type of movement is this
Contraction of the left scalene muscles tilts the head toward the left shoulder is a type of ipsilateral movement.
Ipsilateral is a term used for the location of structures and organs and is based on anatomical position.
In concrete, ipsilateral means that if a rotation is to the "left" the tilt will also be to the same side of the direction of the tilt movement.If we consider the left scalene muscles as a reference, the head toward the left shoulder is considered ipsilateral because the tilt movement is on the same side.Therefore, we can conclude that contraction of the left scalene muscles tilts the head toward the left shoulder is a type of ipsilateral movement.

In a cross of individuals who both possess this genotype, AaBbCc, what proportion of the offspring is predicted to have the genotype, AABBCC
The proportion of the offspring with AABBCC genotype in a cross between two AaBbCc individuals will be 1/64.
Individuals with AaBbCc genotype will produce the following gametes: ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc.
The male and female gametes will randomly unite during fertilization to produce 64 offspring according to the attached Punnet's square.
Thus, only 1 out of the 64 possible offspring can have the genotype AABBCC. In other words, the proportion of the offspring to have AABBCC genotype would be 1/64.

The cAMP receptor protein (CRP) is said to be responsible for positive regulation of the lac operon because ________.
The cAMP receptor protein (CRP) is responsible for the positive regulation of the lac operon because CRP binds to a specific DNA sequence close to the lac promoter, causing increased transcription.
The repressive effect of glucose is effected through a protein called catabolite activating protein (CRP) and cAMP.
The catabolite activating protein (CRP) is a dimer that, when it binds to cAMP, activates and stimulates the transcription of the lactose operon genes.The activator protein CRP-cAMP is necessary for the binding of RNA polymerase to the promoter of the lactose operon genes.Therefore, we can conclude that cAMP and its receptor protein and its binding to the promoter of the lac operon, causes a DNA twist that facilitates the binding of RNA polymerase to the promoter.

Identify a biome and explain how the biotic and abiotic factors affect the biodiversity in that Biome? How are the biotic and abiotic factors related?
Answer:
A large community of plants and animals in a major habitat, such as a desert or a forest. Abiotic factors, such as rain, temperature and sun affect the biome drastically. If there is more rain, there will likely be more plants and animals able to live in that area. If it is hotter and sunnier, less plants and animals will be able to live in the area. Biotic factors, such as beavers in a forest can also change the biodiversity of the area. Beavers create dams which slow the movement of water. This allows other animals that can't swim against strong currents to live in the ponds and lakes the beavers make. This would be impossible if the beavers weren't there.
A growing community considers building a new hospital closer to residential neighborhoods. This will get residents to emergency care faster and save lives when it is needed. The only land available near residential areas is a forested wetland that supports a variety of species. What is a political consequence of not using the land for a new hospital?
Emergency care is farther away, risking the health and well-being of a growing community.
Preserving the ecosystem may upset residents in a community with a hospital shortage.
If there are fewer hospitals, it can slow down the number of new medical career opportunities.
It protects the lives of species and prevents a reduction in carbon sequestering by the trees.
A political consequence of not using the land for a new hospital is that preserving the ecosystem may upset residents in a community with a hospital shortage.
A very important consideration when citing infrastructure is the environmental impact of such projects. This is because, infrastructure is built on land at the expense of the ecosystems that survive in such habitat. Building the said hospital is going to have the negative impact of decrease in biodiversity.

According to the model represented in the diagram, which of the following would cause the cell to not express the lacZ, lacY, and lacA sequences?
A. Binding the RNA polymerase to the gene
B. Removing the Inducer
C. Preventing the repressor from binding to the lac operon
Answer:
the answer would be a
Explanation:
When the inducer is removed from the lac operon model, then this will result in hindering the expression of lacZ, lacY, and lacA sequence in the cell. Thus, the correct option is B.
What is lac operon?Lac operon is a model which contains genes that are involved in metabolism of the cell. The genes are expressed only when the lactose is present in the medium and glucose is absent. The lac operon is turned on and off in response to the glucose and lactose levels in the medium: catabolite activator protein (CAP) and lac repressor. The lac repressor is responsible for blocking the transcription of the operon.
The lac operon can be switched off i.e., the expression of genes can be stopped by removing the inducer molecule from the medium.
Therefore, the correct option is B.
