How many times and during which phase of meiosis do the chromosome replicate?

Biology
1 answer:
Travka [436]2 years ago
6 0

Interphase is divided into three phases, G1 (first gap), S (synthesis), and G 2 (second gap). During all three phases, the cell grows by producing proteins and cytoplasmic organelles. However, chromosomes are replicated only during the S phase. It is the preparatory phase for the cell before cell division.

(opening the door) describe the work of at least 3 body organ Systems that work during the process.
My name is Ann [436]
Explanation:

When a person opens the door, he or she uses 3 systems:

1. Nervous system: from the nervous system, neural instructions are generated through electrical impulses towards the muscles of the upper limb so that they make the necessary movements to open the door.

2. Muscular system: through the muscles of the trunk and the upper limb, it generates voluntary movement to open the door.

3. Skeletal system: the bones are the support of the soft tissues and the fulcrum of most of the skeletal muscles. In this sense, it serves as a support for the muscles of the trunk and the upper limb to carry out the movement of opening the door.

we can conclude that the correct answer is:

Answer:

1. Nervous system: instructions are generated from the nervous system by means of electrical impulses towards the muscles of the upper limb so that they carry out the necessary movements to open the door.

2. Muscular system: the muscles of the trunk and the upper limb generate voluntary movement to open the door.

3. Skeletal system: it supports the muscles of the trunk and the upper limb to carry out the door opening movement. It also has joints that help the mechanical movements necessary to open the door.

Match the following. 1. (pl. gametangia) an organ of lower plants, some protists and some fungi, that produces gametes gonad 2.
Dmitry [639]

The correct matching is as follows-

1. (pl. gametangia) an organ of lower plants, some protists and some fungi, that produces gametes- gametangium.

2. the reproductive cell in sexual reproduction- for example, the egg or sperm.

3. gamete-producing organ in animals - gonad.

4. cone-bearing plant - gymnosperm.

5. the condition of having isogametes - isogamy.

Gametangium refers to the specialized organ of algae, fungi, ferns and other plants involved in the production of gametes. A female gametangia is called the archegonia producing the egg cells and the male gametangia is called the antheridia producing the sperm cells.

Sexual reproduction is characterized by the production and fusion of the male and female gametes called the sperm and the egg respectively.

The gamete producing organ in animals is called the gonads. It is the testis in the male and the ovary in the female.

Gymnosperms are naked seeded plants. The scales or leaves modified to form the male and the female cones.

Isogamy is a type of sexual reproduction that involves the gametes of similar morphology with similar size.
