Each sieve tube element is normally associated with one or more nucleated companion cells, to which they are connected by plasnodesmata (channels between the cells). Each companion cell is derived from the same mother cell as its associated sieve tube member. Sieve tube members have no cell nucleus, ribosomes, or vacues. Thus, they depend on companion cells to provide proteins, ATP, and signalling molecules
Answer:
Is there more to the question? I'm not sure what this would be.
The correct reference for the isotope of carbon that has 6 protons and 8 neutrons is carbon -14. (Solution: C)
Carbon-14, 14<span>C, also referred toa as radiocarbon, is a radioactive isotope.Its atomic nucleus contains 6 protons and 8 neutrons.
</span>It is used to estimate the date at which an organism died. The reason is b<span>ecause </span>carbon-14<span> decays at this constant rate.</span>
This is true that The mutation rate would also be higher.
<h3>What is mutation?</h3>
A mutation is a change in the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA's genome. DNA or RNA can be found in the viral genome.
Environmental elements known as mutagens are what trigger mutations. Radiation, chemicals, and pathogenic agents are examples of mutagens. Mutations may occur naturally spontaneously.
Because it generates a new DNA sequence for a particular gene, the mutation is crucial in the initial stage of evolution because it results in the creation of a new allele. Through intragenic recombination, recombination can also produce a new DNA sequence (a new allele) for a particular gene.
