a. This is an illustration of a(n) limiting factor.
Limiting factor is the factor that absence/presence will limit the growth of the organism. In this case, rain would be the limiting factor. The absence of rain will cause lower plants population which are the primary producer. Lower plant population will decrease the consumer population too. In other words,

b. The biotic and abiotic factors share a(n) ecosystem
Abiotic factor is a factor that composed of the non-living component while the biotic factor is the living organism. In this case, rain would be the abiotic factor. Flower, insect, frog, and bird would be the biotic factor. They both share an ecosystem where they interact with each other.

Jesse has a class project. She wants to show how CO2 from the atmosphere gets converted to carbonates. What kind of process woul

spin [16.1K]

Answer;

-Photosynthesis

Explanation;

-Photosynthesis is referred to as the process where plants use energy from the sun, carbon dioxide, and water to make food. Photosynthesis is largely responsible for maintaining and producing oxygen content of the atmosphere of the earth and then supplies all organic compounds and energy which is necessary for life.

- Carbon dioxide may be removed from the atmosphere when it is used by plants and algae for photosynthesis, dissolved in water, or deposited in the sediments on land or in the ocean. During photosynthesis there is photosynthetic conversion of carbon dioxide into carbohydrates by plants, releasing oxygen in the process.

A corn plant known to be heterozygous at three loci is testcrossed. The progeny phenotypes and numbers are as follows:+ + + 455a

astraxan [27]

Answer:

The progeny phenotypes and numbers are as follows:

+ + + 455-------- parental

a b c 470-------- parental

+ b c 35----------- recombinant

a + + 33---------- recombinant

+ + c 37------------ recombinant

a b + 35--------------- recombinant

+ b + 460---------- parental

a + c 475----------- parental

Total 2,000

+ + + 455-------- parental

a b c 470-------- parental

+ b + 460---------- parental

a + c 475----------- parental

It is two point testcross

So the parental ++ (455+460); ac (470+475)------------------++/ac

Gene order is ------------- ++/ac

+ b c 35----------- recombinant

a + + 33---------- recombinant

+ + c 37------------ recombinant

a b + 35--------------- recombinant

sum of recombinants--------------140

Frequency of recombintion= recombinants/total x100

Map distances between a-c = (140/2000) x 100 = 7 mu

a------------------7 mu -----------------c
