The nitrifying bacteria will convert ammonia to nirites in the nitrogen cycle. this will happen in first stage. correct me if im wrong
A.chromosomes aligning themselves at the equator.
<h3>What distinguishing features of mitosis' metaphase?</h3>
A phase of cell division known as "metaphase" (mitosis or meiosis).Individual chromosomes are typically dispersed throughout the cell nucleus.The chromosomes of the cell condense and move toward one another, aligning in the center of the dividing cell, and the nucleus of the cell disintegrates during metaphase.
<h3>What distinguishes metaphase from other phases?</h3>
Its alignment of a duplicated chromosomes at the metaphase plate, an equatorial plate, is what gives metaphase its name.Via microtubules attached to its kinetochore, one of the sister chromatids is joined to one pole of the cell, and the other sister chromatid is associated to the other pole.

Answer: The only reaction performed by chloroplast through its chlorophyll is photosyntesis. Therefore the chemical formular is below.
C02 + H20 → C6H1206 + O2+ H20.
(carbondioxide) + (Water) Chlorophyll (glucose) +(oxygen)+ (water)
and
enzymes .
This is the single reaction of the process of photosynthesis.However two interconnected reactions are involved light dependent stage and light independent stage.
The first reaction takes place in presence of sunlight, and it is called Photolysis of water.it is the spiting of water to H+, electrons and Oxygen. This is the source of oxygen seen above.
4 H20→ 4H+ + 4e- + 02.
The light independent stage; the hydrogen ion from the photolysis is transfer to the light independent stage to reduce the C02 to produce glucose.In the first equation seen above.
Since chloroplast performs photosynthesis through action of its chlorophyll, The above reaction describes the chemical formula.
B.
The cell wall of plants is made up of the middle lamella, the primary cell wall and the secondary cell wall .
<u>Cellulose</u><u> a complex carbohydrate is the major components</u>. It contains, monomers of glucose in small units linked to one another by bonds.
C
Vacuole helps in plant turgidity needed for uprightness. when filled with water provides turgor pressure increases as the cell membrane pushes against the cell wall. The resulted turgidity helps the plants to maintain resistance to external pressure and therefore resist the effects of gravity.
1. breeding of individuals that have genes for two different characteristics:
DIHYBRID CROSS.
We call it a dihybrid cross when we are considering a cross between two different traits.
"di" means having two traits involved (for example, trait A and trait B), the "hybrid" means that each trait will have two different alleles (for gene A: A or a; for gene B: B or b), one is dominant and the other is recessive.
2. a grid system used to predict possible combinations of genes due to random fertilization: PUNNETT SQUARE
The Punnett square is a grid system that helps us predict an outcome of a cross or a breeding experiment. We this, we can determine the probability of an offspring having a particular genotype.
This is very useful when we are considering more than one gene, making it less confusing.
3. a condition in which both alleles are dominant: CODOMINANCE
Tere 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.
4. when more than two alternatives exist for a gene: MULTIPLE ALLELES
Mendel thought that only two possible alternatives could exist for a gene, but there are cases that have more than 3 possibilities. Some of those can be really popular in a population while others not so much.
This happens with rabbit's fur. They can be black, brown, grayish,
Himalayan patterning or white fur.
5.a condition in which neither pair of alleles is dominant or recessive, so the traits blend in the phenotype: INCOMPLETE DOMINANCE
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.
Answer:
false
Explanation:
not everyone has radial symmetry
