How do roots and seeds get energy?

2 answers:

6 0

Plants absorb water from the ground up through their roots. During photosynthesis, the energy from the sun splits the water molecules into hydrogen and oxygen. The oxygen molecules are given off by the plant and emitted into the atmosphere. Molecules of ATP are created within the plant cell. Seeds are their own energy source, a plant in embryo form. They store energy in a form that is released and used only when water, oxygen, soil, and a close-to-ideal temperature are a part of their surroundings. Until then, they remain dormant. Germination inhibitors are part of the make-up of every seed.

You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype?. . . Condu

DENIUS [597]

If it displays the dominant genotype, we can assume that this plant would have a heterozygous (hybrid) genotype, i.e.

With a purebred recessive plant, the geneotypes would be 50% Bb and 50% bb.

With a purebred dominant plant, the genetpyes would be 50% BB and 50% Bb.

With a heterozygous (hybrid) plant, the genotypes would be 25% BB, 50% Bb and 25% bb.

This diagram shows the menstrual cycle.

LiRa [457]

Answer:

According to the hormone diagram of the menstrual cycle, the woman is not pregnant due to the behavior of progesterone and estrogens, whose levels do not increase, in addition to the absence of human chorionic gonadotropin.

Explanation:

The graph shows the behavior of hormones during a woman's menstrual cycle in the absence of pregnancy.

During a woman's normal cycle, estrogen, luteinizing hormone (LH) and follicle stimulating hormone (FSH) tend to increase prior to ovulation, reach their peak values at ovulation, and then decline, as shown in the graph. Progesterone, on the other hand, increases after ovulation and decreases if the woman does not become pregnant.

In the case of a pregnant woman:

Estrogens continue to increase after ovulation, produced by the ovaries and placenta.
Progesterone also increases its levels, as it is a hormone produced by the ovaries and placenta.
Hormone human chorionic gonadotropin (HCG) appears and increases during pregnancy, due to the secretory activity of the placenta.

The diagram represents the normal cycle of a woman who is not pregnant.

A performer, seated on a trapeze, is swinging back and forth with a period of 8.90 s. If she stands up, thus raising the center

iren2701 [21]

Answer:

8.800s

Explanation:

When the performer swings, she oscillates in SHM about Lo of the string with time period To = 8.90s.

First, determine the original length Lo, where for a SHM the time period is related to length and the gravitational acceleration by the equation

T = 2π×√(Lo/g)..... (1)

Let's make Lo the subject of the formulae

Lo = gTo^2/4π^2 ..... (2)

Let's put our values into equation (2) to get Lo

Lo = gTo^2/4π^2

= (9.8m/s^2)(8.90s)^2

------------------------------

4π^2

= 19.663m

Second instant, when she rise by 44.0cm, so the length Lo will be reduced by 44.0cm and the final length will be

L = Lo - (0.44m)

= 19.663m - 0.44m

= 19.223m

Now let use the value of L into equation (1) to get the period T after raising

T = 2π×√(L/g)

= 2π×√(19.223m/9.8m/s^2)

= 8.800s
