Why is it important for a cell to be able to turn a gene off?

Answers

Answer 1

Answer:

Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example. Gene regulation also allows cells to react quickly to changes in their environments.

Cetacean

Explanation:

Let us start with the family Delphinade which is the largest in the Cetacean order, and relatively recent: dolphins evolved about ten million years ago, during the Miocene. Dolphins are among the most intelligent animals and their often-friendly appearance and seemingly playful attitude have made them popular in past and current human culture.

With your knowledge on base pairing, correctly work out the complementary strand for the given DNA molecules:

Answers

Answer:

Please find the complementary pair of each DNA strand below.

1. CTT GTA GTC A

GAA CAT CAG T

2. GGC ATG CTT C

CCG TAC GAA G

3. GAC TTG GTT C

CTG AAC CAA G

4. CTG AAG TGG C

GAC TTC ACC G

Explanation:

DNA is a double-stranded molecule i.e. it consists of two strands that are complementary to one another. According to the complementary base pairing rule, adenine base (A) will always hydrogen pair with Thymine base (T) i.e. A-T while Guanine base (G) will always hydrogen pair with Cytosine base (C) i.e. C-G.

Hence, based on the above explanation of complementary base pairing, the complementary pair of each DNA strand in this question are as follows;

What are three ways that plants impact the cycle ?

Answers

Answer:

Carbondioxide gas, release oxygen and provide food.

Explanation:

Plant absorb carbondioxide gas, release oxygen and provide food to the animals are the was that plants impact the cycle. Plant absorb carbondioxide gas from the surrounding air in the presence of sunlight and absorb water from the soil. Both carbondioxide and water react with each other in leaves producing glucose and oxygen. Glucose is stored in different parts of plant body whereas some oxygen is used by the plant for respiration and the remaining is released in the atmosphere. The food produced in the plant can be eaten by the primary consumer for their growth and in that way the ecosystem moves in forward direction.

a vial with water,bromothymol blue,carbon dioxide , and a plant are left for 24 hours in the light. the color of the solution turns from yellow to blue . this color change is due to the plant

Answers

The dissolution of bromothymol blue into the solution can change the colour of the solution from yellow to blue.

Why the colour of the solution change?

The color of the solution turns from yellow to blue color due to the release bromothymol blue because plant can't absorb bromothymol blue so it dissolved in the solution which leads to the change of colour of the solution from  yellow to blue.

So we can conclude that the dissolution of bromothymol blue into the solution can change the colour of the solution from yellow to blue.

In human species, the allele responsible for myopia is dominant over
the allele responsible for normal vision.
A heterozygous myopic man marries a woman with normal vision.
1- Designate, by symbols, the corresponding alleles.​

Answers

Answer:

'M' for dominant whereas 'm' for recessive allele.

Explanation:

Allele used for myopic man is 'M' whereas the allele used for normal vision is 'm'. The 'M' represents that the allele is dominant and the 'm' refers to the recessive allele. When the dominant allele combine with recessive allele, the organisms have physical features from the dominant organisms while on the other hand, the recessive allele hide and do not appear in the physical appearance of that organisms.

Visible light and ultraviolet (UV) light are both forms of electromagnetic radiation, and waves of each travel at the same speed. Human eyes are unable to see UV light because it is not in the visible range of the electromagnetic spectrum. If the frequency of one UV light wave is twice that of a visible light wave, how will their wavelengths compare? A. The wavelength of the UV light wave will be half that of the visible light wave. B. The wavelength of the UV light wave will be twice that of the visible light wave. C. The wavelength of the UV light wave will be four times that of the visible light wave. D. The wavelength of the UV light wave will be the same as that of the visible light wave.

Answers

If the frequency of one UV light wave is twice that of a visible light wave, then the wavelength of the UV light wave will be half that of the visible light wave (Option A)

UV is a type of electromagnetic radiation that shows a range of wavelengths from 10 nanometers (nm) to 400 nm, whereas visible light shows a range of wavelengths from 400 to 700 nm (0.4 to 0.7 µm).

UV light exhibits a higher frequency and shorter wavelength than visible light.

The frequency is a unit measured in Hertz (Hz) which indicates the number of cycles (i.e., the waves) that pass a point in space during one sec.

The longest wavelength of visible light is the red color (700nm), whereas and the shortest visible wavelength is blue (400nm).

The frequency of the visible light ranges from 7.5×10¹⁴ Hz (blue color) to 4.3×10¹⁴ Hz (red color); whereas the frequency of UV light ranges from 800 terahertz (THz) to 30,000 THz.

Answer:

Proton

Explanation:

Neutron are neutral, ion I am not sure but are not positive, and electron are -.

Answer: Proton

Explanation:

In an atom there exist three types of sub atomic particles

1) Electrons

2) Neutrons

3) Protons

so we know that electrons are negatively charged particles which stays in a finite orbit as per their energy level

Protons are positively charged particles which remains inside the nucleus and they are tightly bound inside it

Neutrons are neutral sub atomic particles which do not have any charge in it.

So we have correct answer as
