Helppp, i’m going to fail:(

Don’t worry this is pretty easy :)

The answer is -
50% recessive alleles
50% dominate alleles

explication- find out what alleles you’re working with (heterogeneous and homogeneous)
[heterogeneous is 1 dominant and 1 recessive- homogeneous is 2 of the same alleles they can be dominant or recessive]
We’re working with a parent with heterogeneous and another parent with recessive homogeneous.

draw a allele chart
__
|_|_|
|_|_|
they look like this and take your first parents alleles and put them at the top

L s
_ _
|_|_|
|_|_|

it should look like this, then take your parent with both recessive and put them vertical to the box

L s
_ _
s |_|_|
s |_|_|

it should look like this, now you drag one letter down and one letter across for each box

L s
__ __
s|Ls|ss |
s|Ls|ss |
— —
it’s should look like this when they’re done, i think you’re doing a grade below me in biology so the ratio should be 50/50 for both phenotype and genotype.

TRY TO LEARN THE VOCABULARY IT HELPS A LOT AND BASICALLY TELLS YOU THE ANSWERS!
GOOD LUCK :)

What is the similarity and difference for j and k
valentina_108 [34]

Your right J is sexual reproduction, and K is asexual reproduction. But sexual reproduction requires the presences of a male and a female. But other asexual reproduction doesn't, and just requires sexual maturity. They produce offspring in the form of spores for example.

how are mitochondrial genes typically inherited? an individual randomly inherits their mitochondrial dna from either parent. an
dybincka [34]

An individual inherits their mitochondrial DNA from their mother.

The little circular chromosome contained inside mitochondria is called mitochondrial DNA. These organelles are the heart of the cell and are present in all eukaryotic cells. The only way for mitochondria and their DNA to be transmitted from mother to child is through the egg cell.

Mitochondrial inheritance: The mitochondria in this particular type of inheritance have their own DNA. Only illnesses resulting from mutations in the mitochondrial DNA are solely passed down through mothers.

Because sperm contain few mitochondria and these break down after fertilization, an individual's mitochondrial DNA is solely acquired from the mother.

How are photosynthesis and cellular respiration different?
kari74 [83]

Answer:

The correct answer is B photosynthesis stores energy,while cellular respiration releases energy.

Explanation:

Photosynthesis is an anabolic process that utilizes the atmospheric CO2 along with water molecule as a electron donor to generate glucose sugar and oxygen gas.Photosynthesis helps to store the light energy in form of chemical energy in the bonds of glucose molecules produced during photosynthesis..

 on the other hand cellular respiration is a catabolic process that oxidizes glucose to generate energy in form of ATP along with CO2 and water as a byproduct.
