Answer:
<h3>
The Prokaryotic Cell</h3>
Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
Answer:
The amount of energy the flowing H(+) ions have
Explanation:
Hope it helps.
<span> COMPLETE DOMINANCE:
</span>
<span>Mendel concluded that some alleles are dominant and others are recessive. When one dominant allele is present, it's enough to make the recessive allele unexpressed (this is what happens in heterozygous individuals). In other words, it 'hides' or masks the recessive allele.
CO-DOMINANCE:
-a condition in which both alleles are dominant.
</span>
There are alleles that have the capacity of dominating at the same time, and when an organism is heterozygotic, both alleles are expressed.
For example, a white chicken(WW) crossed with a black chicken (BB): 100% of the offspring being WB. With this genotype, they have black feathers and white feathers.
It's not a blend of colors, but a case where both are expressing.
INCOMPLETE DOMINANCE:
-a condition with none of the alleles is dominant or recessive, so the traits blend in the phenotype.
Some alleles are not completely dominant, and when that's the case the phenotype of a heterozygous organism will be a mix between the phenotypes of its homozygous parents.
For example:
plant 1: RR -red
plant 2: rr- white
By crossing this plants we will obtain 100% of the offspring with a color mix: pink.(genotype: Rr)
Red and white are not completely dominating so it results in a blend of colors.
SEX LINKED TRAITS
Sex chromosomes contain genes that determine the sex of a person. Two X chromosomes result in a female and one X plus a Y result in a male.
In those chromosomes, there are genes specific for each gender, and in those chromosomes, there are genes that code for certain traits- the sex-linked traits.
These traits will be inherited according to the sex chromosomes they receive from their parents.
The three phases of the human ovarian cycle are:
<span><span>1. </span>Follicular phase</span>
This is a phase controlled by estradiol, during which follicles in the ovary mature.
<span><span>2. </span>Ovulation</span>
This is a phase in which eggs are released from the ovaries when the follicles rupture.
<span><span>3. </span>Luteal phase</span>
<span>This is the phase is under the control of progesterone. At the beginning of luteal phase, corpus luteum is formed and it ends in either pregnancy or luteolysis.</span>
Octopus<span> muscle fibers run in all directions; when contracted, they form a "skeletal" support system.</span>
