Lysosomes can be compared to the recycling and garbage centers of a city. How can this comparison be justified?
Ivan
I think the correct answer from the choices listed above is the second option. Lysosomes can be compared to the recycling and garbage centers of a city. This can be justified since they <span>digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.</span>

you are studying a bacteria plasmid that contains 5 operons and 15 genes. how many transcriptional promoters are on this plasmid
mojhsa [17]

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.

A mutation causes a tomato plant to have much fewer, smaller leaves. Plants use their leaves to make food. Which best describes
deff fn [24]

Answer:

  • <u> It is harmful because it obviously affects the plant’s ability to survive</u>

<u />

Explanation:

Mutations are alterations in the genetic code that may occur due to environmental or chemical mutagens. Mutagens, are substances or agents that induce changes in the genetic code.

Photosynthesis is a complex biochemical process; plants convert solar energy into chemical energy as sugars like the polysaccharide glucose. They also use inorganic carbon from CO_{2 along with H_{2}O.

Plants photosynthesize in their leaves- these organs contain tissues for  CO_{2 intake, along with the chloroplasts and mitochondria, the sites of photosynthesis and respiration. If the number of leaves are reduced, this reduces the amount of tissue capable of carrying out this essential process, limiting the plant's chance for meeting its energetic needs, and thus survival.
