<span>The fitness boom is not most prominent in lower socioeconomic categories, this is false. Poor people usually do not have the resources to eat healthily, or the time to exercise. Higher socioeconomic capacity have the leisure time and the disposable income to eat healthier foods- premium and organic brands, exercise, and buy expensive exercise equipment.</span>

Find the prokaryotic promoter sequences; Draw boxes around them, Circle the start codon. Then transcribe the following DNA seque
Degger [83]

Explanation:

The transcription is a process which transcribe the DNA into a molecule which could be read by the machinery to translate it into the proteins and that molecule is known as the mRNA molecule.

1.The mRNA molecule is transcribed by an enzyme called RNA polymerase which transcribe DNA in 5'to 3'direction that is DNA strand will be 3' to 5'direction therefore the strand with 3' to 5' will act as template strand.

2. The RNA polymerase binds at promoter region and there are two sequences in prokaryotes at -35 end which is TTGACA and at -10 end which is TATAAT.

3. The translation begins after the start codon which is AUG therefore proteins will be synthesized after AUG.

In the given question, both promoter sequence are present in the 5'to 3'strand

The mRNA will be -

There are two start codon thus two polypeptides will be synthesized.

10. Which of the following statements best describes the major difference between anaphase of mitosis and anaphase I of meiosis?
umka2103 [35]
The answer will be A because mitosis usually separate the sister chromatids to sister chromosomes to form two diploid cells. In meiosis, the goal is to have four haploid cells. To form that, cells need to undergo cell division two times. In the case of meiosis I, sister chromatids stay joined together until it reaches meiosis II. Then, the sister chromatids will separate starting at anaphase II in meiosis II. For example, if you start with 92 chromosomes (46 chromatids) during meiosis I, at meiosis II you will have two cells with 46 chromosomes (23 chromatids). By the end of meiosis II, you should form 4 haploid cells that contains 23 chromosomes.

Lead is toxic, but do you know why?
nlexa [21]

Answer:

Lead is toxic mostly because during biochemical reactions it tries to substitute certain metals. hence while doing this, It disrupts with the proteins that control blood pressure, the production of heme and the formation of sperm. Through reactions that propagate electrical signals in the brain, lead often consumes calcium, which reduces the capacity to think and retrieve information.

Which phrase describes a population?
Sophie [7]

Answer: all the gray squirrels that live in a forest

Explanation:

A population refers to the total number of organisms of the same species living and breeding together in a given area.

Thus, since the gray squirrels all belong to the same specie and live in a given area called forest - population is best described by the phrase "all the gray squirrels that live in a forest"
