Which layer of soil is best for plant growth (ASAP!)

1 answer:

4 0

The A horizon is the best for plant growth, because is has more organic material and more organisms that make the soil more fertile than the deeper layers, and the soil is not loose like the O horizon.

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

Plz answer all 5

Nataliya [291]

Answer:

1. Evolution can be defined as the gradual development of an organism creating diversity.

2. A common misconception is that Homosapiens are descendants of Apes.

3. analogous structures are features of different species that are similar in function, but not necessarily in structure; such as bird wings and insect wings. homologous structures, however, is an organ or bone with similar underlying anatomical features found in different animals; such as the arms of primates.

4. vestigial structures are structures that have no apparent function and appear to be residual parts from a past ancestor, such as wings of flightless birds.

5. Embryology supports the theory that organisms have a common ancestor in accordance to the theory of evolution.
