Claim: Whales evolved from land mammals to water mammals.

Evidence: The first whales evolved over 50 million years. One of the first whales, such as Pakicetus, were land animals with long skulls and carnivorous teeth, much like many adaptable land mammals back then and today.

Answer:

Biogeochemical cycle is a type of cycle in which water moves through the biosphere or living part of the earth surface.

Explanation:

In this cycle, water moves from the living bodies from a number of processes such as transpiration, breathing and evaporation. Water is very important for all living organisms because about 70 % of the body of living organism is made up of water. Water is a universal solvent so that's why plants takes nutrients from the soil with water. Without water plants are unable to take nutrients from the soil so water plays a key role in the survival of living organisms.

A scientist crosses a rabbit with short fur and a rabbit with long fur. which of these outcomes would show that the trait for fu
maks197457 [2]

Answer:

d. all of the offspring have medium length fur.

Explanation:

Incomplete dominance is a phenomenon in which offspring produce a trait that is intermediate between the two forms of a certain trait.

For example: In four o clock plant, some plants produce red flowers while some plants produce white flowers. When plants with red flowers are crossed with plants with white flowers, all the offspring have pink flowers.

Why is that so?

This is because no allele is completely dominant over the other and therefore both contribute their individual effect by producing intermediate phenotype.

Example in question:

Cross between a rabbit with short fur (SS) and a rabbit with long fur (LL)

P1:                                SS        x        LL

Gametes:                     S     and  L

Offspring                        SL :SL

SL: Medium length fur

Therefore this is a case of incomplete dominance.

Hope it help!
