Explanation:

Plants take in co2 and sunlight during photosynthesis to produce glucose. If we remove plants from the ecosystem, there will be nothing to take in the co2 which means there will be a lot of co2 in the atmosphere.

Answer:

The loggers will chop the trees, they will make money which would help the ecosystem. Although the earth would get warmer because the tree will not be using the Co2 for photosynthesis.

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:

Energy stems from the sun

Explanation:

Think about it, A plant takes energy from the sun and then a worm eats it soon after a bird eats that worm then when the bird dies its body is fed to fungi or back to plant life. Pretty much the sun is our biggest source of energy

Also The sun is our major source of heat without the sun we would freeze and perish.

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.

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:

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.

Explanation:

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.
