Answer:
There are from 200-500 million alveoli (mean diameter = 200 micrometers) in adult human lungs
Explanation:
The epithelial cells of the alveolar septum are markedly thinned and the capillary network immediately beneath the epithelium is the richest in the body.hope this helps you :)
The cell transport process that is opposite of the three pictured is call C. exocytosis.
Question:
<em>What is Darwin’s theory of the origin of species?</em>
Answer:
<em>The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.</em>
Hope this helps!
Answer:
b. inside the nucleus of a cell
Numerous catabolic operons have their transcription controlled by glucose. The three enzymes needed for conversion are encoded by the operon's five structural genes.
<h3>How many genes are there in an operon?</h3>
Operons have a transcription promoter at the beginning, two to twelve genes on average, and a transcription terminator at the conclusion (Zheng et al. 2002; Lawrence 2003).
<h3>Yes, there is just one promoter for operons.</h3>
An operon is a group of genes that all use the same transcriptional promoter. Every operon contains regulatory DNA sequences that act as binding sites for regulatory proteins that either promote or inhibit transcription.
<h3>The promoter is a 3 or a 5?</h3>
An area of DNA known as a promoter is where RNA polymerase starts to transcribe a gene. Promoter sequences are often found directly in the genome.
