Which evidence supports the theory of ocean floor spreading?
A) The rocks of the ocean floor and the continents have similar origins.

B) In the ocean floor, rocks near the mid-ocean ridge are cooler than rocks near the continents.

C) The pattern of magnetic orientation of rocks
is similar on both sides of the mid-ocean ridge

D) The density of oceanic crust is greater than the density of continental crust.​

Answers

Answer:

C

Explanation:

Abundant evidence supports the major contentions of the seafloor-spreading theory. First, samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge.

The evidence supports the theory of ocean floor spreading which is the pattern of magnetic orientation of rocks and is similar on both sides of the mid-ocean ridge.

The theory of ocean floor spreading was formulated in 1960 by Harry Hess after studying different ocean floor patterns and formation.

The oceanic crust forms along submarine mountain zones involves the formation of oceanic crust along mid-ocean ridges which then later spread out to other areas. The farther the oceanic seafloor from the mid-ocean ridges , the older they are.

The formation of a new community on land that has never had organisms grow on it before is known as

Secondary succession
Rebuilding
Biomagnification
Primary succession

Answers

Answer: Primary succession

Explanation:

The formation of a new community on land that has never had organisms grow on it before is referred to as the primary succession.

Primary succession takes place when there is no ecosystem that has existed before. It should be noted that the primary ecosystem is a slow process due to the fact that it starts on bare rock. This then provides a habitat which can be colonized. An example of primary succession is when there is eruption of volcanoes.

What is the role of complementary base pairing in the replication of DNA?
A It reduces the number of errors in the process of DNA replication.
B It introduces more hydrogen bonds between the nucleotides.
C It ensures that the replicated DNA is an exact copy of the parent DNA.
D It allows the replicated DNA to have a different nucleotide arrangement

Answers

Answer:

c. it ensures that the replicated DNA is an exact copy of the parent DNA

Explanation:

This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).

20. Genotypes is all bb, phenotype is all blue.

21. 50% TT 50% Tt genotypes, 100% tall phenotypes

Explanation:

To find the genotypes and phenotypes, we do our punnett sqaure by drawing a square, dividing it into 4 squares, putting our cross in and determining the genotypes of our offspring. Since blue eyes are recessive, they'll be represented by bb. Since tall plants are dominant, they're represented by Tt or TT. Capital letters are dominant while lowercase signifies recessive.
