Explanation: Nitrogen cycles through the biosphere through what is known as the nitrogen cycle. The major changes nitrogen goes through are nitrogen fixation, nitrification, anammox, denitrification, and ammonification. ... In nitrification, NH3 is converted to nitrite by microbes known as ammonia-oxidizers

How does independent assortment during Metaphase 1 help produce diversity in gametes (eggs and sperm)?
Svetach [21]

Answer:

a. There are different possible ways that homologous pairs might line up

c. Different alignments of homologous pairs will cause different combinations of alleles in gametes.

Explanation:

The law of independent assortment, proposed by Mendel, states that the alleles of one gene segregate into gametes independently of the alleles of another gene. This means that the segregation of one gene does not affect another. This law of independent assortment is evident during gamete formation in sexually-reproducing organisms know as meiosis. Specifically, in the Metaphase 1 stage of meiosis 1, homologous chromosomes (similar but non-identical chromosomes received from each parent) lines up at the metaphase plate (cell equator).

The lining up of chromosomes in this stage occurs randomly making it possible for chromosomes to align in different possible ways. The way/manner the chromosomes align at the equator determines which chromosome combination gets separated into which gamete. The homologous chromosomes are randomly distributed at the cell's equator before segregates into gametes. This random orientation enables the alleles of each gene on a chromosome to combine in different random ways, hence, allowing genetic diversity in the resulting gametes (sperm and egg) they get segregated into.

A musk ox and the Alstroemeria flower have physical structures and organs that have similar functions. Provide two examples of s
gladu [14]

Answer:

Mammals

Birds

Explanation:

The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.

Organs are the structures that made up of two or more tissues organized to carry out a particular function.

An organ or bone that appears in different animals with same function is called homologous structure.

Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.

Different animals have bones that appear very similar in form or function and seem to be related.

Examples

The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.

The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job.  For example, the wings of bats and birds.
