How does water move from leaves to root?

2 answers:

5 0

First, the water from the leaves is transported to the roots until it reaches the xylem. Second, cohesion and adhesion results the molecules of the water to form a column into the xylem. Lastly, the water will be transported from the xylem into the mesophyll cells, and then evaporates from the surfaces which leaves by the process of diffusion through the stomata.

I hope it helps.

A plant breeder has determined the following variances for yield of corn in his fields:

Law Incorporation [45]

Answer:

A. VG = 80

B. Broad sense heritability = 0.80

C. Narrow sense heritability = 0.30

D. Average yield = 430 Units

Explanation:

A. Given that

VA = 30

VD = 50

VI = assumed not available

Therefore

Total genetic variance (VG) = VA + VD

= 30 + 50

= 80

VG = 80

B. Given that

VP = 100

VG = 80

Broad sense heritability, H2 = VG/VP

= 80/100

= 0.80

C. Given that

VA = 30

VP = 100

Narrow sense heritability, h2 = VA/VP

=30/100

= 0.30

D. The difference in selection = 500 - 400

= 100

Recall,

Selection response is heritability multiplied by selection differential.

That is

R = h2S

Selection differential = 100

Heritability h2 = 0.30

Selection response = 0.30 × 100

= 30units

Therefore, expected average yield = 400 + 30

= 430 Units

Which of the following have been linked to the dramatic global decline of amphibian populations? Select one: a. drainage of wetl

charle [14.2K]

<h2>The correct answer is: e.</h2>

Explanation:

Decline in the global population of amphibians is due to multiple reasons which include:

A moist ecosystem is necessary for amphibians especially for the purpose of their reproduction. The drainage of the wetlands deprives them of their habitat.
Pollutants adversely affects the survival of the gametes, tadpoles or the adult amphibians by acting as toxic agents and inhibiting their normal metabolic function.
Infectious diseases often cause their death resulting their population to decline.
Global climate warming affects their normal metabolic growth and development and hence causes their population to decline.

egoroff_w [7]

The correct answer among the choices provided is option A. Lung capillaries are responsible for exchanging carbon dioxide for oxygen from the air. Blood that comes from the heart gets oxygen from the alveoli. The carbon dioxide in the blood goes into the alveoli at the same time.
