What are three environmental factors that can influence plant phenotypes
sergij07 [2.7K]

The genotype describes the complete set of genes inherited by an individual, and the phenotype describes all aspects of the individual's morphology, physiology, behavior, and ecological relations. Light, water, temperature, soil structure are the environmental factors which influence the plant phenotype most. The growth is a very sensitive phenotypic trait that quickly responds to any sub-optimal environment. However, many more physiological responses occur that turn out in phenotypes that can be measured with non-invasive technology.

15. When there is light, plants do which of the following biological<br> processes?<br> *
zhuklara [117]

Answer: Plants do both photosynthesis and cellular respiration.

Explanation:

All cells do cellular respiration even without light.

Honestly, photosynthesis alone would be right since the teacher didnt  state the questions correctly. But you should choose both cause in the light it does both.

Glycolysis is the first step of cellular respiration, in which glucose is used to generate ATP to power the cell. The major chem
lutik1710 [3]

Answer:

The correct answer is b. C6H12O6 -> 2 C3H4O3+2 H+

Explanation:

Glycolysis occurs in both the condition aerobic and anaerobic so it does not require oxygen. In glycolysis, one glucose molecule is converted into two pyruvate( 2 C3H4O3) and two 2 ATP, 2NADH, and 2 H₂O are produced.

Initially, 2NAD⁺ is produced during glycolysis which is reduced to produce 2NADH and 2 H⁺. Therefore the correct equation is  C6H12O6 -> 2 C3H4O3+2 H+.

Then this pyruvate is used in the Kreb cycle which is required for the complete breakdown of glucose into carbon dioxide and water and this process occurs in aerobic conditions. Complete oxidation is important to produce more energy from partially oxidized glucose.

A planet has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m. Find the weight of a 65.0 kg person at 1000 km above the sur
mote1985 [20]

<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.

<u>Explanation:</u>

To calculate the weight of a person, we use the formula:

w=mg     ....(1)

where,

w = weight of an object

m = mass of the person = 65kg

g = acceleration due to the gravity of the planet

For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:

g=\frac{GM}{r^2}

where, g = acceleration due to gravity = ?m/s^2

G = Universal gravitational constant = 6.67\times 10^{-11}Nm^2/kg^2

M = mass of the planet = 5.97\times 10^{24}kg

r = distance of the person from the planet = 6.38\times 10^6m

Putting values in above equation, we get:

g=\frac{(6.67\times 10^{-11}kgm/s^2.m^2/kg^2)(5.97\times 10^{24}kg)}{(6.38\times 10^6m)^2}\\\\g=9.782m/s^2

Putting this value in equation 1, we get:

w=65kg\times 9.782m/s^2=635.83N

Hence, the weight of the person above the surface of a planet is 635.83N.
