Answer: A ;)

Explanation: DON'T WORRY BOUT IT SWEET HEART

REY [17]3 years ago

Answer:

Magnetic reversal proves seafloor spreading because we can see the polarity of the Earth's magnetic field in rocks. As magma cools, particles in it get “frozen” in the direction of the magnetic field. ... The magnetic evidence shows that the oldest rocks are far away from the ridge and the newest rocks are closest.

When roots take up mineral ions, they are built up against their concentration gradient. both anion and cation transport utilize
attashe74 [19]
I believe the answer is B, primary active transport. Root hair cells in plant use active transport to absorb mineral ions such as nitrates from the soil. The concentrations of minerals in the soil are lower in the soil than in within the root hair cell, therefore the transport will be against the concentration gradient which does not favor diffusion, therefore the pant has to use active transport.

What is the purpose of alternative splicing in eukaryotic cells? What is the purpose of alternative splicing in eukaryotic cells
Komok [63]

Answer:

Produce multiple polypeptide sequences from a single primary transcript.

Explanation:

Some genes produce more than one type of protein since the primary transcript encoded by these genes undergoes alternative splicing. These genes mostly have one segment that can serve either as intron or exon. Also called differential splicing, alternative splicing removes the segment as intron but retains it as an exon.

Splicing of the single primary transcript in different ways produces more than one version of mRNA from a single primary transcript encoded by a single gene. The alternative splicing allows the cells to produce multiple types of troponin proteins from single genes. These different troponin regulation muscle contraction in different muscles
