Answer:

The correct answer is ''undergo irreversible repression.''  

Explanation:

The morphological and physiological transformation of meristematic cells into adult or differentiated tissues constitutes the process of cell differentiation. This, and the consequent specialization of the cell, bring about the division of labor, forming cells with specific functions. Differentiation occurs by differential activation of some genes and repression of others. Depending on the position it occupies, each cell receives certain stimuli to develop the corresponding activities. During the differentiation process, cells undergo a series of changes in their characteristics and there is a readjustment in their mutual relationships.Different molecular factors initiate and drive the programming / reprogramming of cell fate through the modulation of specific genomic and epigenomic patterns, which regulate the expression of activator / repressor genes of the main fundamental and specialized cellular processes. Thus, the differentiated cell will express certain genes and acquire certain functions.Adult stem cells are responsible for maintaining the different types of specialized cells that make up the body. Asymmetric cell division in stem cells has emerged as one of the main physiological mechanisms that regulate the number of cells and their diversity to maintain tissue homeostasis. A large number of molecules, generically called determinants of cell fate, participate in the regulation of asymmetric division. Asymmetric division of somatic stem cells produces both a stem cell and a progenitor. The initial progenitor cells, through new cycles of asymmetric cell division, finally reach their terminal state of cell differentiation, due to changes in intracellular and extracellular (environmental) signaling. After cells leave their mother state and begin to differentiate, they make exclusive selections for phenotypic pathways through secondary genomic / epigenomic modifications, mainly to different types and gradients of transcription factors (physiological programming of cell differentiation). This leads, for example, to activation of specialized biosynthetic pathways, remodeling of the cytoskeleton, and repression of cell proliferation signaling. The expression of genes is regulated mainly at the level of their transcription. Transcription factors correspond to proteins with the ability to interact with specific DNA sequences and trigger their transcriptional activity. Most transcriptional factors contain different domains that participate in different aspects of protein function; they generally contain two domains: a domain that binds to specific DNA sequences and an activation domain that regulates transcription by interacting with other proteins. In the regulation of gene transcription, in addition to transcription factors, coactivating and corepressor molecules participate, which bind to them, modifying their activity in a positive or negative sense. Each cell type has a characteristic pattern of gene transcription, which is determined by the binding of combinations of transcription factors to the regulatory regions of a gene.

Cellular differentiation progressively restricts cell fate because the unexpressed genes in the cell are undergoing irreversible repression.

Gene repression is the switching off of unique genes whose products are needed to support the function of the cell such as the production of vital enzymes or cofactors.

This is specifically important if the products of such genes are not long-lived and deteriorate, or are metabolized.

Thus, option "D" is undergo irreversible repression.

Answer: The answer is the green part of the plant faces away because it cannot perform photosynthesis without light.

Explanation: The reason for this is because sunlight is always important to receive while performing photosynthesis because without sunlight, the plant would lose one of its major factors for photosynthesis.

Answer:

Protein channels in the plasma membrane allow the ions to cross.

Protein channels which are present in the plasma membrane of the cell allow the ions to cross the plasma membrane. Thus, the correct option is C.

Channel protein is a kind of protein which is found embedded in the plasma membrane of the cell. Channel proteins function similar to a pore and it allows the diffusion of small ions and water molecules through them. Channel proteins are lipoproteins and these are synthesized in the rough endoplasmic reticulum of the cell near the nucleus.

Ion channels are the transmembrane proteins whose canonical function is the transport of ions and molecules across the plasma membrane to regulate cell membrane potential and also play an essential role in neural communication, nerve conduction, and muscle contraction in the body.

Therefore, the correct option is C.

Answer:

Positively charged amino acids

Explanation:

Heparin is an acid polysaccharide that has a strong negative charge due to the sulfate groups on its glucosamine residues. This negative charge confers to heparin anticoagulant activity. The negatively charged groups in the heparin molecule can interact with positively charged (basic) residues, such as arginine (Arg) and lysine (Lys) of plasma proteins. For example, it has been shown that lysine amino acid residues of antithrombin III may be involved in the binding with heparin.

Explanation:

It depends if the genotypes are hetero.zygous or resessive/dominant homo.zygous. Being colorblind could be represented by a resessive genotype like, bb. if their son/daughter has Bb or bb or their son/daughter in law has a resessive trait then having a color blind grandchild maybe possible. The colorblind grandson has parents that both have at least 1 resessive trait, then the grandson could not be colorblind.

Explanation:

hormones of adrenal medulla are Adrenaline and non- Adrenaline. they are the derivatives of amino acids called Tyrosine( aromatic Amino acid)

The hormones of the adrenal medulla are modified versions of amino acids. Thus, the correct option is B.

The adrenal medulla may be defined as an internal part or region of the adrenal gland which is located at the region of the top of each kidney.

The adrenal gland is a small gland that comprises the adrenal cortex and adrenal medulla. The adrenal cortex synthesizes steroids hormones like mineralocorticoids, glucocorticoids, etc. While the adrenal medulla is responsible for the secretion of epinephrine and norepinephrine.

The hormone epinephrine is also known as adrenaline. It is often called catecholamine. This epinephrine is extracted from the derivatives of amino acids known as tyrosine.

Therefore, the hormones of the adrenal medulla are modified versions of amino acids. Thus, the correct option is B.
