Describe the similarities and differences between the structure of the xylem and the phloem.

1 answer:

7 0

The Xylem transports minerals and water from the roots and the phloem transports food to other parts of the plant such as the leaves. They are both vascular tissues of the plant for the transportation of food.

REY [17]

Answer:

Explanation:

Group of answer choices DNA sequences that are deduced by comparing many related DNA sequences are called CONSENSUS. Unlike DNA synthesis, RNA synthesis requires TRANSCRIPTION. PROMOTERS direct RNA polymerase to the initiation site. RNA synthesis complexes containing DNA, RNA, and polymerase perform TRANSLATION. RNA synthesis (tRNA, mRNA, and rRNA) takes place in complexes containing DNA, RNA, and polymerase are called TRANSCRIPTION BUBBLES. The expression of beta-galactosidase requires the induction of operons by addition of REPRESSORS.

While the introduction of the mutant synthetase gene restored some of the growth characteristics, this strain still does not gro

katen-ka-za [31]

Answer:

A and D

Explanation:

Transfer ribonucleic acid (tRNA) is a type of RNA that decodes mRNA (messenger RNA) into protein. This phenomenon is known as translation.

If the strain of mutant synthetase gene does not grow fast despite having growth characteristics, the following possibilities could happen:

Sometimes histidine tRNA sends asparagine instead of histidine to other proteins where histidine residue should have been present for growth.

The normal synthetase might be present but not in an adequate amount.

The steps in the process of endochondral ossification are a: Ossification center forms in the diaphysis b: Cartilage calcifies a

irina1246 [14]

Answer:

During the development of the fetus, the mechanism by which the mammalian skeletal system gives rise to tissues of the bone is termed as endochondral ossification. Endochondral ossification also plays an essential role at the time of the development of the long bones length, rudimentary generation of the long bones, and healing of bone fractures naturally.

The following are the steps in the process of endochondral ossification:

f. The development of the cartilage model.

b. The calcification of cartilage takes place and the formation of bone collar occurs.

a. In the diaphysis, the formation of the ossification center takes place.

c. In the epiphysis, the formation of ossification centers takes place.

d. Replacement of cartilage takes place by the bone.

e. Ossification of epiphyseal plates takes place.

Photosynthetic algae create sugars that will eventually be broken down during which process

Leya [2.2K]

The breaking down of sugars is called glycolysis. The prefix glyco- means sugar, and the suffix -lysis means breaking down. It's part of a three-step process in respiration, the other two is The Krebs Cycle and Electron Transport Phosphorylation. In the process of glycolysis, 2 ATP and 2 NADH are produced.
