Answer:

d is the answer to this question

Chromosome is a structure found inside the nucleus of a cell and are made up of DNA molecules, histones, and nucleosomes. So, option (c) is correct.

Chromosomes are organized into structures that resemble threads. Each chromosome is structurally made up of DNA that is tightly wound around unique proteins known as histones.

A single nucleosome is made up of a core of histone proteins and roughly 150 base pairs of DNA. The nucleosomes constantly fold in on themselves to compact and tighten the bundled DNA during the formation of a chromosome.

Therefore, option (c) is the correct answer. Chromosome include DNA molecules, histone protein and nucleosome.

Answer:

C. Messenger RNA is an output for the process of transcription and an input for the process of translation.

Explanation:

Transcription is where DNA is copied to form RNA. Translation is the process where mRNA is converted to proteins. Therefore mRNA is the output of transcription and the input of translation.

The statement which is true about inputs and outputs of transcription and translation is as follows:

Thus, the correct option is C.

Transcription may be defined as a process through which a cell constructs an RNA copy in the form of a messenger RNA from a piece of DNA. This biological process of protein synthesis occurs in the nucleus of the cell.

While translation may be defined as a process through which a form of messenger RNA converts into specific amino acid sequences to form a particular protein. This process of gene expression occurs in the cytoplasm of the cell.

In transcription, DNA acts as input while mRNA is output, in translation, this same set of mRNA acts as input while the sequence of amino acids is output.

Therefore, messenger RNA is an output for the process of transcription and an input for the process of translation. Thus, the correct option for this question is C.

Specialized cells are stem cells that turn into cells with specific functions

Specialized cells are differentiate into cells with specific functions.

Cells are the fundamental cornerstones of all life. Numerous numbers of cells construct the human body.

The process by which dividing cells alter their functional or phenotypical type is known as cell differentiation. All cells, it is assumed, derive from stem cells and acquire their functions as they mature.

In response to antigen exposure, some differentiation occurs. Differentiation alters a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals significantly.

These changes are primarily the result of highly controlled changes in gene expression and are the subject of epigenetic research.

Mesenchymal stem cells, epithelial stem cells, and muscle satellite cells are the three types of differentiated cells.

Thus, the answer is differentiation.

The nucleus contains the genetic material within a cell, because it's the main part of the cell that carries most information :3

Explanation:

:3

The genetic material of a cell is present within the nucleus of cell. Nucleus contains DNA and RNA of the cell, RNA undergoes translation to form various proteins.

A nucleus is the membrane-enclosed organelle within a cell which contains the genetic material of the cell in the form of chromosomes. An array of pores present in the nuclear membrane allows the selective passage of certain molecules through the nucleus such as proteins and nucleic acids into and out of the organelle.

The nucleus controls and regulates all the cellular activities such as growth and metabolism. It contains the hereditary information of an organism. Nucleolus are the small bodies which are often seen within the nucleus. The gel-like matrix which contains the nuclear components is the nucleoplasm.

Explanation:

Answer:

There is much evidence supporting the evolution of various species, but the reason its so controversial is because of us. Lots of scientists refuse to believe any higher power is involved in the making of humans, and therefore we evolved from a common ancestor as other mammals did. But others argue that humans are completely different, simply because the higher power in question made us in their image.

The medium-sized finch consumes seeds as food. The bill shapes of the birds vary from person to individual; some have broad, deep bills, while others have narrower beaks. Smaller beaked birds are more efficient at eating little, soft seeds than larger beaked birds at eating large, hard seeds.

A dry spell in 1977 changed the island's vegetation. After this time, the quantity of seeds drastically decreased, with small, soft seeds experiencing a bigger decline than large, hard seeds. The following year, the large-billed birds fared better than the small-billed ones in terms of survival.

When the Grants assessed beak sizes in the drastically reduced population in the year after the drought, they discovered that the average bill size was higher.

This provided unequivocal proof that the availability of seeds led to natural selection of bill size. The Grants were aware that selection would result in the development of bill size since they had examined the inheritance of beak sizes and saw that large-billed birds that survived would typically prefer to have children with larger bills.

The Grants' further research has shown how selection for and evolution of this species' larger bills occurred in response to other changing island conditions. When large seeds started to become scarce, the evolution happened both to larger beaks, as in this instance, and to smaller banknotes.
