Biology

miskamm [114]3 years ago

is a functional unit that results from interactions of abiotic, biotic, and anthropogenic components and are a combination of interacting, interrelating parts that form a unitary whole.  Ecosystems vary in size.  They can be as small as a puddle, or as large as the earth itself.  Basically, any living and non-living things interacting together can be considered an ecosystem.  Within each ecosystem, there are habitats that vary in size.  A habitat is a place where a population lives.  A population is a group of living organisms of the same kind living in the same place at the same time.  Natural ecosystems are made up of abiotic factors such as air, water, rocks, and energy and biotic factors such as plants, animals, and microorganisms.

PSYCHO15rus [73]

Answer:

Which type(s) of cell division reduce(s) the chromosome number by half?

                           Meiosis l

Which type(s) of cell division can be classified as reductional?  

                            Meiosis I

Which type(s) of cell division can be classified as equational?

                           Mitosis and Meiosis II

Explanation:

Meiosis is a type of cell division which occurs in the germ or reproductive cells to produce gametes. It is completed in the two stages, meiosis I and meiosis II.  The cells which are going to divide by meiosis are diploid having two sets of chromosomes. Meiosis I is the first stage of the meiosis. At the end of meiosis I two daughter cells are formed having only 1 set of chromosomes and chromosome numbers are reduced to half. Thus, meiosis I is a reductional division.  

Mitosis and meiosis II is the equational division as after division chromosome number remains the same as in the parent.

<span>Georgio instantly feels pain due to the message carried to his brain by </span>myelinated axons.  The message of the ache is carried by unmyelinated axons.
The myelinated axon is highly "insulated" axon that r<span>eceives input and transmit impulse quickly.</span>
The purpose of the naked axon with larger dendritic field which is called unmyelinated axon is to receive as much input as possible.
