Neither of these are minerals, B.

Its not A because, they are not natural materials but instead made up of natural materials, like a rubber tree.

Its not D because, concrete is not a mineral and has indefinite composition.

slavikrds [6]

Answer:

The importance of having the US Forest Service, the Bureau of Land Management, US Fish and Wildlife Service, and the National Park Service is to manage land resources for conservation and the development of natural resources.

Explanation:

The US Bureau of Land Management was mainly established to manage lands for different uses;

The US Forest Service was established to sustainable management of forest resources vis a vis conservation and sustainable usage;

The US Fish and Wildlife Service was established to conserve and protect wildlife/fishes with end goal being in the benefit of the populace;

The National Park Service was established to oversee all the National Park Systems and ensure that their intensities are maintained for the continuous enjoyment, entertainment as well as education of the masses.

If the main aim of establishing each body is examined closely, it would be discovered that their primary function is to manage land resources, conserve biological diversity and the environment's integrity as well as oversee the use of land and the resources it contains.

There are no choices given, but the event was most likely a physical one that would have barred the squirrels from seeing each other. Squirrels are a social creature, and the event that would have separated the populace could have been anything from a large fire to an earthquake that separated the squirrels from each other.

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
