Answer:

A. 1:2:1 Ratio

Explanation:

Because there are 2 of the same physical appearances and 2 different ones… therefore it’s be 1 for the first box 2 for the identical ones and 1 for the bottom right box: 1:2:1

Hope this helps, good luck a have a great day!

Answer:

C. 3 : 1

Explanation:

because if T is the allele for height

3 offsprings would be tall and 1 would be small.

T is the dominant trait and dominant trait expresses itself when paired with another dominant allele or even recessive allele.

( as for TT, Tt the dominant trait will express itself and the offsprings would be tall)

t is the recessive trait and it expresses itself only when both the connected alleles are recessive.

(as in tt, the offspiring would be small )

2. Why is hydrogen placed in group one of the periodic table?

romanna [79]

Answer:

because, it resembles the properties of alkali earth metals as well as halogens ! OwO

Explanation:

" Hydrogen resembles the properties of alkali earth metals as well as halogens. Hydrogen has one electron in its valence shell and it also needs one more electron to get stable. ... For this the hydrogen is placed separately in periodic table ! "

Under anaerobic conditions, such as intense exercise, pyruvate is converted to ____________ . This 3-carbon molecule travels thr

stiv31 [10]

Answer:

Under anaerobic conditions, such as intense exercise, pyruvate is converted to lactate. This 3-carbon molecule travels through the blood to the liver, where it can be converted to glucose by the cori cycle.

Under aerobic conditions, pyruvate enters the mitochondrion, where it is converted to acetyle CoA . This 2-carbon molecule goes on to participate in a series of oxidative reactions called the Citric acid cycle.

Explanation:

In the question ,among the given 6 options ,the simplest way to find the answer can be ,to find either the option is aerobic (presence of free oxygen ) or anaerobic (lack of free oxygen). Among the options , glucose is an incorrect option as it is a carbohydrate and used in respiration process .In aerobic process ,the glucose can be break down but in anaerobic ,it can only be used.

Other option is ATP- ATP is the energy source of the cell and used for storing energy or reactions of the cell,thus this option do not belong to the given question.

thus its clear the rest four options are the answer .

among four two options belong to aerobic and the rest two are anaerobic.

Under anaerobic conditions-

The pyruvate is converted into lactate because under the absence of oxygen only the NAD+ can be regenerated, thus further can allow glycolysis.

The cori cycle is also called lactic acidic cycle, thus this cycle is a metabollic pathway produced by anaerobic glycolysis (which takes place by regeneration of NAD+)transporting the molecules from blood to liver and further converting to glucose

Under aerobic conditions,-

The pyruvate is converted into Acetyle CoA so as to further produce citric acid and then citric acidic cycle. Thus Acetyle CoA forms more ATP which help in the regeneration of NAD+ and production of citric acid cycle takes place.

HENCE , The correct options are - lactate cori acetyle CoA citric acid.

Which of the following terms is used to describe the steady breeze of particles flowing out from the sun?

STALIN [3.7K]

<h2>Answer:</h2>

The term is solar wind.

<h2>Explanation:</h2>

The breezy particle which is produced from the corona region of the sun is called as Solar wind. It is made up of electrons, protons and alpha particles with kinetic energy. Implanted inside the sunlight based breeze plasma is the interplanetary attractive field.

The sun oriented breeze shifts in thickness, temperature and speed after some time as the sunlight changes. Its particles can get away from the Sun's gravity on account of their high vitality coming about because of the high temperature of the crown, which is caused due to source of origin called corona.
