Answer:

medulla is a set of cells that runs through a hair.

Explanation:

The medulla is typically different depending on the species that the hair came from, which makes it one way to distinguish between animal and human hair. Forensic scientists may also look at the shape and color of pigment in the hair and whether or not the hair has been dyed or bleached. As hair grows about one centimeter a month, it may be possible to determine how long it has been since the hair has been dyed or bleached by looking at the natural end of the hair. Forensic scientists also examine hair for any abnormalities or deficiencies that may help them determine whom the hair came from.

In beans the pod texture and growth form genes are located on different chromosomes. There are two varieties of beans in a farme

irina1246 [14]

Answer:

a. Genotype in F1 - TtBb

Phenotype in F1 - tough pods, bush-type growth

b. Proportion of F2 that are heterozygous for bush-type growth form = 5/8

c. Proportion of the F2 with tender pods = 1/4

d. Proportion of F2 that are heterozygous for growth form and have tender pods = 1/8

Explanation:

Since the two traits are located on different chromosomes, they will independently assort during gametes formation. T is dominant over t and B is dominant over b.

Two true-breeding varieties were crossed at the beginning of the program:

TTBB x ttbb

All F1 plants will have the genotype TtBb with tough pods and bush-type growth form.

Advancing the cross to F2:

TtBb x TtBb

Progeny

1 TTBB - tough pods, bush-type

2 TTBb - tough pods, bush-type

2 TtBB - tough pods, bush-type

4 TtBb - tough pods, bush-type

1 TTbb - tough pods, climbing-type

2 Ttbb - tough pods, climbing-type

1 ttBB - tender pods, bush-type

2 ttBb - tender pods, bush-type

1 ttbb - tender pods, climbing-type

Proportion of F2 that are heterozygous for bush-type growth form = 10/16 = 5/8

Proportion of the F2 with tender pods = 4/16 = 1/4

Proportion of F2 that are heterozygous for growth form and have tender pods = 2/16 = 1/8

How does the earth system rely on on energy from the sun

Colt1911 [192]

The sun's heat supplies and is used in many earth processes such as life and temperature, maintaining balance.

1. Photosynthesis and sustain life
2. Climate and temperature

The one component in photosynthesis that can't be recycled but must be constantly available is energy.

Light energy, mostly from sunlight, is the main requirement for photosynthesis to occur. 

Photosynthesis is a process wherein light energy is converted into chemical energy. 

Chemical energy is generated to support the various activities of a plant or an organism.
