Explanation:

Glucose molecules together form cellulose, which builds or adds strength to cell walls. Glucose molecules also form carbohydrates. When combined with nitrates from the soil, glucose will form amino acids

C. Consider the impact of their actions, is the correct answer.

A is not correct because recycling helps protect the environment and helps boost the economy. B is not correct because plants helps supply oxygen for humans and animals. It is also a food source for some animals and humans. C. is not correct because we need to save energy for a healthier and cleaner planet.

Answer:

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.

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.

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.

The statement that accurately describes the role of the light-independent reactions is as follows:

Thus, the correct option for this question is B.

The light-independent reactions of photosynthesis occur in the stroma of the chloroplast in the presence of light itself. Rubisco is involved in this type of reaction. The Final product of this reaction is the production of carbohydrates. It also involves the fixation or reduction or assimilation of Carbon dioxide.

In the light-independent reaction, the light energy is transformed into chemical energy which is then transferred to the high-energy sugars component in order to derive energy for metabolic activities. The storage of high-energy sugar for future use when direct sugar is not available is also accomplished in this reaction.

Therefore, the correct option for this question is B.

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.

Answer:

monohybrid

Explanation:

Answer:

True!

Explanation:

Sometimes an entire ocean closes as tectonic plates converge, causing blocks of thick continental crust to collide. A collision mountain range forms as the crust is compressed, crumpled, and thickened even more. The effect is like a swimmer putting a beach ball under his or her belly—the swimmer will rise up considerably out of the water. A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.
