<h3>Plants absorb soil nitrogen through their root</h3>

systems in the form of amino acids, nitrate ions (NO3 -), nitrite ions (NO2 -), or ammonium ions (NH4 +). Most of the nitrogen in the cells and tissues of terrestrial animals can be traced back to the consumption of plants at some level of a food chain.

<h3>Can plants absorb nitrogen through leaves?</h3>

Plants are already known to use their leaves to absorb inorganic airborne nitrogen molecules, such as ammonia or nitrogen dioxide, and turn them into amino acids. And a relatively reactive compound called peroxyacetyl nitrate can be absorbed by leaves, although it's not clear whether plants actually use it.

Someone please help me with Punnett square

anygoal [31]

Answer:

1. Phenotype ratio = 3:1

Genotype ratio = 1:2:1

2. Phenotype ratio = 4:0

Genotype ratio = 4:0

3. Phenotype ratio = 1:1

Genotype ratio = 1:1

Explanation:

According to this question, a gene coding for tallness is involved. The allele for tallness (T) is dominant over the allele for shortness (t). The phenotype and genotype ratio of each parental combinations is given in the attached punnet square.

1. Tt × Tt

In this cross, both parents (Tt) will produce T and t gametes. Using this in a punnet square, the offsprings will be as follows: TT, Tt, Tt, and tt. Hence, The phenotype ratio is 3 tall: 1 short while genotype ratio is 1(TT): 2(Tt) : 1(tt).

2. TT × tt

In this cross, TT will produce T gametes while tt will produce t gametes. Using this in a punnet square, all offsprings will be heterozygous "Tt". Hence, The phenotype ratio is 4 tall: 0 short while genotype ratio is 4 (Tt) : 0 (tt).

3. tt × Tt

In this cross, tt will produce t gametes while Tt will produce T and t gametes. Using this in a punnet square, the following offsprings will result: Tt, Tt, tt and tt. Hence, The phenotype ratio is 1 tall: 1 short while genotype ratio is 1(Tt) : 1(tt).

WILL GIVE BRAINLIEST!!!!!!!!!

Galina-37 [17]

Answer:

Mitochondria and chloroplasts likely evolved from engulfed bacteria that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic bacterium, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion. (nature.com)

Hoochie [10]

Answer:

Incomplete dominance

Explanation:

A phenotypic "blending" of two traits is referred to as incomplete dominance, indicating that neither trait is truly dominant over the other. Instead of one color overpowering expression of the other, both colors are expressed simultaneously.

Codominance suggests that both phenotypes are dominant, but cannot be expressed at the same time. The result of codominance would be regions of dominant red expression and regions of dominant white expression, resulting in spots rather than blending.
