Answer:

1. The lack of clean water can affect people's lives because people use water for everyday things. If people do not shower with clean water, then what is the point of showering at all? Also, people use water to cook, so if people are using dirty water then you could get sick. Some people do not buy water, so you would have to boil the water each time you want to drink it. This is how a lack of clean water could affect people's lives.

2. There are many things that could change people's lives positevly. For example, if you move to a new state where it is warmer. If you go to a new school you could make new friends. Also, somebody new could move in down the street and you could have more friends. Even something as small as eating your favorite meal for dinner could change your life. You could remember it as being amazing. These are how changes (small and large) could change somebody's life.

Explanation:

Some of the sequence of DNA given is in 3' to 5' direction, mRNA sequence is also given.

The DNA is double stranded helix which replicates by semi conservative mode. The two strands unwind to act as a template for other strands. In transcription the 3' to 5' strand acts as a template because RNA synthesis takes place in 5' to 3' direction. mRNA is single strand. It has nucleotides in it from which 3 base pairs acts as a code for amino acid.

The following table shows DNA strand having complementary sequaence and mRNA synthesized.

Does carrying capacity influence the survival of a population?

aivan3 [116]

'<span>Does carrying capacity influence the survival of a population?'

The answer you're looking for is something along the lines of Yes, because a carrying capacity that is too small will be easy prey, while a carrying capacity that is too large will consume it's needed resources too quickly.

Hope this helped!</span>

In negative control of transcription by the lac operon, how does the presence of an inducer affect transcription?.

ss7ja [257]

If the inducer [allolactose] is present in the negative control then it will bind to the repressor decreasing its ability to bind to the operator due to which the transcription begins again and the operon is turned on.

Lac Operon is a set of three genes z, y & a which are regulated under the same promoter which regulates the amount of lactose production in the cell.

An inducer is a molecule that has the ability to induce or activate the operon. ex- in the case of the lac operon, allolactose acts as an inducer.

A repressor is a molecule that will repress or restricts the transcription of the genes of the operon, as a result, the operon will be switched off.

When the lac operon is under negative control, with no CAP [catabolite repressor protein] binding activity, the repressor remains active and thus binds to the operator region of the operon, as a result, no transcription takes place and the operon will be switched off.

But if the inducer will be present even in the negative control then the transcription takes place and the operon will be on.
