What is the role of oceans in the carbon cycle?

Maslowich

Answer:

Don't worry I'm here to help

Explanation:

The ocean plays an important part in the carbon cycle.

Overall, the ocean is called a carbon 'sink' because it takes up more carbon from the atmosphere than it gives up.

Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter.

Glad I could help!!

An imbalance from the homeostasis perspective is considered to be

Aleks [24]

<span>When there is an imbalance from the homeostasis of the body, a disorder or disease may result. Homeostasis establishes balance and equilibrium of the internal and external part of the body. If this balance or ideal levels are interrupted, the body may correct it by making all system work together or the problem may worsen based on certain influences and may not allow normal functioning of the organism, by either deficiency or toxicity. </span>

Moreover, some factors that influence the body’s ability to maintain homeostatic balance are genetics, lifestyle choices and environmental exposure.

Imagine that a given species has a gene for hair color (B = dominant brown, b = recessive white) and a gene that controls hair l

serg [7]

Answer:

Phenotypes: All Brown Hair Color and All Short Hair Length

Genotypes:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)

Explanation:

Hair color :

B = dominant brown

b = recessive white

Hair length :

S = dominant short

s = recessive long

The dihybrid cross between parents with the genotypes:

BBSS × BbSs

If BBSS self crossed; we have the following traits= BS, BS, BS, BS

If BbSs self crossed; we have the following traits= BS, Bs, bS, bs

The dihybrid cross is as follows:

BS BS BS BS

BS BBSS BBSS BBSS BBSS

Bs BBSs BBSs BBSs BBSs

bS BbSS BbSS BbSS BbSS

bs BbSs BbSs BbSs BbSs

Phenotypes = All Brown Hair Color and All Short Hair Length

Genotypes include:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)
