Why is the nucleus called the "control center" of the cell?​

Answers

Answer 1

Answer:

because it gives signals out to the rest of the cell.

Explanation:

Answer 2

Answer:

because it controlls all the activities of the cell including cell reproduction, heredity. these proteins in turn, form the structural units of cells and control all chemical processes within the cell.

Answers

Answer:

nitrogen gas, dentrification

Explanation:

APES class

Nitrates are the compounds that are converted back into the atmospheric nitrogen and the process is called as denitrification. The atmospheric nitrogen is given back to atmosphere and the composition of nitrogen is the most highest in the atmosphere.

What is the composition of atmospheric nitrogen in atmosphere ?

The atmospheric nitrogen is the highest amount in the atmosphere that  is 78% where the nitrogen is present in different forms.

The process where the ammonia and the nitrates along with the nitrites are given back to the atmosphere via nitrification, ammonification and denitrification. There are certain bacteria in the atmosphere as well that fix the nitrogen.

Rhizobium and Nitrobacter are the bacteria that help to fix the nitrogen present in soil as well. Nitrogen fixing bacteria is present in the root nodules of gram plant.

transcribe the following DNA sequence to RNA use no spaces in your answer and use all caps. DNA:TACGCTTTACGAGACCCAATC

Answers

Answer:

RNA: UACGCUUUACGAGACCCAAUC

Explanation:

During transcription, a specific DNA sequence is used as template to synthesize a specific RNA sequence, usually a messenger RNA (mRNA). During this process (transcription), Uracil (U) bases replace Thymine (T) bases. Transcription has three stages: initiation, elongation and termination. Subsequently, the resulting mRNA is used to synthesize a protein, in a process known as translation.

The number of chromosomes is DOUBLED after mitosis. True or False, AND explain.

PLEASE HELP IT'S DUE TODAY!!!!

Answers

Answer:

False

Explanation:

The number of chromosomes is doubled during mitosis, but each daughter cell (new cell) has the same number as the mother (original cell)

Mitosis is a cell division cycle in which the parent cell divides to produce equivalent daughter cells. It can occur in the body for growth, replacing dead cells etc.

The statement is False.

The sentence can be explained as:

Mitosis is a function of division in cells in which the two exact daughter cells are produced from the parent cell division of the nucleus and cytoplasm.

The parent cells undergo the doubling of the hereditary content by the process of central dogma during the synthesis stage.

The parent and daughter cell is diploid during this sort of cycle and does not get halved or duplicated at the end of the cycle.

Therefore, chromosomes do not get doubled at the end of the division.

Which of the following molecules are produced during transcription? (3 points)

Messenger RNA
Ribozymes
Ribosomal proteins

I only
I and II only
II only
I, II, and III

Answers

Answer:

1. and 2. only

Explanation:

rRNA is sometimes called a ribozyme or catalytic RNA.

Molecules of rRNA are synthesized in a specialized region of the cell nucleus called the nucleolus, which appears as a dense area within the nucleus and contains the genes that encode rRNA.

mRNA is Messenger RNA which are synthesized during DNA transcription as templates for the production of a specific proteins.

The molecules are produced during transcription are - Messenger RNA and Ribozymes that is - I and II only.

Transcription is the first step in decoding a cell's genetic information. During transcription, enzymes called RNA polymerases build RNA molecules that are complementary to a portion of one strand of the DNA double helix

the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA)carried out by an enzyme called RNA polymeraseproduces a number of accessory proteins called transcription factors.Ribozymes are catalytic RNA molecules. They have the intrinsic ability to break and form covalent bonds in RNA molecules

thus, The molecules are produced during transcription are - Messenger RNA and Ribozymes that is - I and II only.

Frog's evolutionary pathway resembles the water cycle. This is quite fitting, because all frogs statistically enjoy bodies of water. Seafrogs absorb salt-water through holes, which emit inside the snout. First, they grow two limbs, or legs, to swim. These turn into fins, which, eventually, allow for hopping and balancing-capacity. Capabilities, include: tongue-roll, sticky toes, bubbly neck, multi-eggs, and more

Photosynthesis uses all of the following except

carbon dioxide
O light energy
O chemical energy
water


is it’s A?

Answers

Answer:

No I think its C

Explanation:

Photosynthesis is a process that takes place due to water, sunlight, carbon dioxide and creates oxygen.

All the green plants carry out the process of photosynthesis in the presence of sunlight, the carbon dioxide, and water.  

Thereby releasing oxygen and energy. The first organism that evolved to make photosynthesis was the blue-green algae and later on, cyanobacteria evolved which lead to the origin of oxygen on the earth.Thus the photosynthesis is a process that results when all three are processes by the plants.  

Giving out the chemical energy in the form of sugar and air to breathe. Hence the correct option is C.

Explanation:

The end result of repeated experiments supporting a hypothesis is for the hypothesis to become a theory.

In science, a hypothesis is a general statement that needs to be validated or invalidated by experiments. Once a hypothesis is found to be valid by several independent but similar experiments, such a hypothesis becomes a theory.

Formulation and testing of hypotheses (via experiments) represent two of the key steps in the scientific method.
