The Drilling sample of the Seafloor spreading theory helped in determining rock ages on the floor of ocean.

Explanation:

The formation of crusts of ocean by the process of volcanic eruptions in the ridges of the middle ocean is the theory of seafloor spreading proposed by Hammond Hess. The movement of tectonic plates continuously forms sea floors through spreading of seafloor.  The several evidences in support of this theory has been seen, of which some are – molten material eruptions, magnetic stripes in rocks and rock ages.

The drilling evidence is the final one that was proved by taking samples of rock by drilling in ocean and by bringing them with pipes. The observation of these rocks proved that older rocks were collected from farther ridges and youngers are found in the central ridges.

Based on the data in Table 1, identify the animal that has the greatest number of sequence differences from the reference animal
Doss [256]

Answer:

( please like and hope it helps)

A) Elephas-2 has 13 sequence differences from the reference animal, and this is the greatest number of animals in the table.

B) From left to right, the order at the tips of the cladogram is: Dugong , Elephas , Loxodonta , Mammathus.

(Loxodonta and Mammuthus can also be reversed)

C) The molecular data, such as that for are widely conserved protein such as cytochrome b , show conserved similarities between organisms such as to dugongs and proboscideans and can be used to support the existence of this relationship.

D) The animals that are related ones had a common assister with certain genetic characteristics. Adaptation to different habitats leads to diversification of morphology but does not change evolutionary relationships.

in pea plants round seeds are dominant and wrinkled seeds are recessive. the cross rr x rr, what percentage of the offspring wil
In-s [12.5K]

Answer:

0%

Explanation:

Round = Dominant

Wrinkled = recessive

Recessive = r

Dominant = R

homozygous dominant = RR

homozygous recessive = rr

Heterozygous= Rr

Since both seeds are homozygous recessive (rr)

In your punnet square, one lower case r will go on the top and the left side

r r

r

r

Something like that.

Go across your four boxes and you will end up with;

rr, rr

rr, rr

In order for it to be round, at least one box would need to have to be a heterozygous(Rr) or be a homozygous dominant.

What can we expect to happen to these strawberry plants

Answer:

I think you forgot to include a photo but.

The plant will absorb water and sun as the strabbaries slowly develop, once they are finished they will soon be eaten by predadores.
