Basically, the cell wouldn't be able to "breathe," as the mitochondria is where the respiratory functions of the cell happens. No energy would be produced, and then the cell would stop moving and die.

When plants make flowers, gene A is expressedin whorls 1 and 2, gene B is expressed in whorls 2 and 3 and gene C in whorls 3 and
Sati [7]

Answer:

The correct answer would be option D) no gametes.

Explanation:

The ABC model of the flower was formulated to describe the collection of genetic procedures that determines floral organs in several plants. These species consist of four whorls which are sepals, petals, stamens, and carpels. These whorls are expressed by the expression of a number of genes present in each whorl or verticli.

Gene A is solely responsible for the sepals while the co-expression of A and B genes are responsible for the petals. The identity of the stamens is expressed by B and C and the carpels require C and D genes to be active.

The homozygousity for a normal mutation in gene C will lead to inactive or lack stamens and carpels, which are male and female reproductive organs. These are an important structure for forming gametes.

Thus, the correct answer would be option D) no gametes.

Give the role of air in an ecosystem
Radda [10]

Sustain Life and Growth

Air consists one of the main life-sustaining gas called oxygen. Almost all living things breathe in and breathe out this air. Nitrogen and Carbon dioxide are also other gases that are vital for plants and their growth.

Combustion

Apart from this, air supports burning or combustion. The oxygen present in air help in burning of the fuels to basically carry out activities like cooking food, running industries and vehicles as well as generating heat and electricity.

Temperature Control

Another important aspect of air is that it helps in maintaining the temperature on the earth surface by circulating hot and cold air. Air acts as a conductor of heat as well. Even phenomena such as water cycle are dependent on air.

Supplier of Energy

Air which consists of energy is one of the main suppliers of energy. Living things are made up of cells and these cells extract oxygen within the blood to produce energy usually in the form of ATP. This biochemical generation of ATP is essential to maintain life on the earth.

Photosynthesis

Carbon dioxide, which is a component of air is used by plants during the process of photosynthesis. Here oxygen is also released by plants. And we already know how vital oxygen is.

Which of these values would most likely be the heritability of body mass index (BMI) in a developing country with a large gap be
ANTONII [103]

Which of these values would most likely be the heritability of body mass index (BMI) in a developing country with a large gap between nutrition and health care available to the rich and poor?

a. 0.33

b. -0.88

c. 0.99

d. 0.0001

e. 1.3

Answer:

a. 0.33

Explanation:

Body Mass Index is defined as the measure of fat depending on the height and weight of individuals. It is being calculated as: BMI=\frac{mass_{kg}}{height_{m^2}}

The most likely heritability of body mass index(BMI) in a developing country with a large gap between nutrition and health care will be 0.33.

These is because in developing countries especially countries experiencing rapid economic growth as illustrated by the annual GDP growth rate are likely to have widely ranging lifestyles due to influences of the burgeoning economy, Therefore, there are greater chances for the rich  to have access to the basic requirements and necessities of life whereas the poor are limited with either low or no access to adequate nutrition and health care.
