There are three phases in an action potential. they are __________.

Biology
1 answer:
luda_lava [24]3 years ago
3 0
The three stages of Action Potential are:
1. depolarization- Na+ channels open up inside of the membrane and becomes more positive than the RMP.
2. repolarization- The Na+ channels inactivating and K+ channels opening AP spike stops rising to which the membrane returns to RMP.
3. hyperpolarization- A few of the <span>K+ channels remain open and the Na+ channels reset inside of membrane becomes more negative than RMP.

Hope this helps!

Answer:

UNICELLULAR, MULTICELLULAR, OR COLONIAL EURKAYOTE WHOSE CELL WALLS MAY CONTAIN CELLULOSE; CAN BE PLANTLIKE, ANIMAL-LIKE, OR FUNGUS LIKE

a) IF IT IS A EUKARYOTE, BUT NOT AN ANIMAL, PLANT, OR FUNGI THEN IT IS A PROTIST

1. Protists are classified more easily by what they are not than by what they are

a) Protists are not animals, plants or fungi because they do not have all of the characteristics necessary to place them in any of these kingdoms

2. Kingdom Protista was created to include this diverse group of more than 200,000 organisms

3. ALL PROTISTS ARE EUKARYOTES WHICH MEANS THEY HAVE MEMBRANE BOUND ORGANELLES AND A DNA FOUND IN A MEMBRANE BOUND NUCLEUS

a) like all eurkayotes, the DNA of protists is found within the membrane bound eukaryotes, there are remarkable differences in their reproductive methods

b) Some reproduce asexually by mitosis while others exchange genetic material during meiosis

PROTISTS ARE CLASSIFIED BASED ON THEIR METHOD OF OBTAINING NUTRITION

1. There are divided into three groups using this method:

a) animal-like protists/protozoan

b) plantlike protists/algae

c) fungus like protists

HETEROTROPHIC, UNICELLULAR, ANIMAL LIKE PROTIST

1. Usually ingest bacteria, algae, or other protozoans

2. REQUIREMENTS:

a) ingest food, heterotrophs

b) no cell walls

3. Some are parasites

1. Cillates

2. amoebas

3. apicomplexans

4. zooflagellates

5. paramecium

Answer:

The correct answers would be maintain chromosome number through generations  and cause genetic variations by recombination.

In Meiosis a cell divides into four daughter cells all of which have half the number of chromosomes present in a parent cell.

It helps in the formation of gametes in sexually reproducing organisms.

These gametes (one from father and one from mother) fuse together to form a zygote. It re-established the chromosomal number as that of the parent.

In absence of meiosis, the chromosomal number would have doubled after each generation.

In addition, the meiosis also increases the genetic variation among the population with the help of crossing over which occurs during the pachytene stage of prophase I.

During this event, genetic information is exchanged between the non-sister chromatids of the homologous chromosomes. It produces a new combinations of genes that are different from either parent.
