Describe how the role of phloem would would be affected if the leaves start to die off
Naya [18.7K]
The conductive tissues of the angiosperms are the xylem which drives the raw sap and the phloem which conducts the elaborate sap.The phloem, or liber, drives the elaborate sap, solution of organic substances rich in carbohydrates, from the leaves to the other organs.

The elaborate sap (which contains organic substances produces by photosynthesis) is produced in the leaves, where the majority of the chlorophyll subsist, so if the leave die off, the production of organic substances and the elaborate sap are reduced, so its transport by the phloem will be reduced, and this is how the phloem will be affected by the dying of the leaves.

The ability of the human body to break down the red color in beets is controlled by an autosomal dominant allele. The inability
Zinaida [17]

Answer:

Explanation:

<em>Let the ability to break down the red color in beets be represented by the allele </em><em>B</em><em>. The inability would be represented by the allele </em><em>b</em><em>.</em>

A nonsecretor's genotype would be BB or Bb while a secretor's genotype would be bb.

A nonsecretor woman with a secretor father would be a carrier with genotype Bb. A nonsecretor man who in a previous marriage had a secretor daughter would also be a carrier with genotype Bb. If the two marries:

            <em>Bb     x     Bb</em>

<em>            BB    2Bb    bb</em>

1.

(a) probability of their first child will be a secretor girl = probability of having a girl and being a secretor.

Probability of having a girl = 1/2

Probability of being a secretor = 1/4

<em>probability of their first child will be a secretor girl</em> = 1/2 x 1/4 = 1/8

(b) Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor.

Probability of having a girl = 1/2

Probability of being a nonsecretor = 3/4

<em>Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor</em> = 1/2 x 3/4 = 3/8

2. <em>Probability that their first two children will be nonsecretors of either sex = probability of their first being a nonsecretor and of either sex and probability of their second being a nonsecretor and of either sex.</em>

  = 3/4 x 3/4 = 9/16

The immediate energy system (ATP-PC) relies on:
swat32

Answer:

c. the high-energy phosphates stored in muscle cells

Explanation:

Phosphocreatine (PC) or creatine phosphate is a compound rich in energy. It has energy stored in it which can be used to phosphorylate ADP into ATP. The phosphocreatine is stored in muscle cells when muscles are not working. The produced ATP serves as an energy source for muscle contraction. The creatine produced during ATP production is phosphorylated again into PC using ATP when muscles are resting.
