A gene sequence reads ATCGAT. which represents a substitution mutation.

Biology
1 answer:
KIM [24]3 years ago
4 0

Answer:

D

Explanation:

A substitution is where a base is substituted by another base

A. ATGAT  - this is not a substitution, the C has been <u>deleted</u>

B. UAGCUA  - this is not a substitution, but is the complementary mRNA sequence (you can tell because there are Us instead of Ts)

C. TAGCTA  - this is not a substitution, but is the complementary DNA sequence

D. ATGGAT​ - this is a substitution, the C in the original sequence has been replaced (substituted) by a G.

1. Describe at least two things people can do today to help protect Earth and reduce levels of CO2.
kondaur [170]

<span>1.       </span><span>Two ways that man can reduce the global warming is by reducing carbon dioxide (a greenhouse gas) emissions. One way is by planting more trees. Forests are reservoirs for carbon since their remove carbon dioxide from the atmosphere in the process of photosynthesis. Second is by reducing the use of fossil fuels to produce energy. Fossil fuels are the biggest emitter of carbon dioxide in their combustion</span>

<span>2.       </span>Greenhouse<span> gases permit infrared rays from the sun to pass through them but do not allow heat to escape into the atmosphere. When infrared hits the earth's surface it turns to the heat wave that has much longer wavelengths. This causes the earth’s atmosphere to retain more heat hence increased global temperatures.</span>

<span>3.       </span><span>When greenhouse gases especially carbon dioxide are reduced in the atmosphere, the earth is able to radiate more sunlight back into space due to the reduced greenhouse effect. This enables the global temperatures to remain low. At the poles where temperatures are cold remains even colder hence the waters in these regions turn to glaciers. The ice continents increase in size and hence a big characteristic of ice ages. </span>

<span>4.       </span><span>Humans are not responsible for global warming even though they contribute but in minimal proportions as compared to the natural process. This is because it is estimated that termites produce even more carbon dioxide than humans. Ice ages and global warming are therefore natural cycles governed by the sun. However, human activity aggravates global warming. </span>

Almost 50 percent of water withdrawn in the US, is used up by thermoelectric power plants. The table below shows the amount of w
sp2606 [1]

Answer:

The number of thermal power plants increased between 1950 and 1975.

Explanation:

Here, the table that shows the amount of water withdrawn in billion gallons per year, between 1950 and 2005,

Year              1950            1965            1975            1990           2005

Amount         180              340             420               410              410

Since, 420 > 180,

Also, 50 percent of water withdrawn is used up by thermometric power plants.

Thus, thermal power plants in 1975 > thermal power plant in 1950

Therefore, the number of thermal power plants increased between 1950 and 1975.

Second option is correct.

Note : first option is incorrect.

Since, by the above table,

The least amount of water used by power plant is 180 billion gallons per year,

Thus, third option is incorrect,

Now, the table does not represents energy produced,

Fourth option can not be said correct.

PLS HELP!! ILL MARK BRAINLIEST
True [87]

Answer:

1. While Biology is the study of living things, living things themselves are made up of chemical composition. Our survival is dependant on the reactions taking place inside and outside the body. Hence, to understand living things, biologists needs a good understanding of chemistry.

2. 170 pm is the radius of a Carbon Atom.

3. The vast majority of the mass of an atom is concentrated in its nucleus

4. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.

5. Neutrons are located with protons in the nucleus; they too exchange mesons with protons and with each other to form the strong nuclear force, but they do not have to overcome the repulsion from Coulomb forces since neutrons are not charged.
