Andrews [41]2 years ago
4 0

Answer:

Energy is said to flow in a "one-way stream" through an ecosystem. In your own words, describe what that means. Energy is not recycled. Energy enters an ecosystem and flows through a food chain, but it is not reused, it is lost as heat.

Hope the answer helps:)

Infer How do dominant and recessive<br> factors interact? sc.7..16.1
Rama09 [41]

Answer:

The resulting characteristic is due to both alleles being expressed equally. An example of this is the blood group AB which is the result of codominance of the A and B dominant alleles. Recessive alleles only show their effect if the individual has two copies of the allele (also known as being homozygous) If you were to talk about dominant and recessive factors in human traits, such as brown/green eyes, brown would be dominant, only needing to be in 1 parent to pass down to the child. (i have no idea if this helps or not-- it's all i know.. sorry, ;w;)

What happens to mRNA after it completes transcription?
Nana76 [90]

The correct answer is "C."

mRNA stands for messenger Ribonucleic acid.  The role of mRNA is to carry genetic information for the synthesis of protein from the nucleus after transcription.

After the transcription process is over, the mRNA leaves the nucleus and heads to the ribosomes in the cytoplasm where translation of this information takes place.

The ribosomes are the work bench of the cell. They receive the mRNA with its coded information, read it and translate it and with the help of tRNA (transfer RNA), amino acids are fetched from the cytoplasm and linked together to form the exact protein that was coded for on the mRNA.
