Both mitosis and meiosis begin with a parent cell that is diploid. Which of the following best describes how mitosis and meiosis
ANEK [815]

Answer:

meiosis you will have four haploid cells (half the number of chromosomes is a diploid cell) and after mitosis you will have two diploid cells

Explanation:

Mitosis you begin with a parent cell that is haploid, it copies all it's chromosomes and splits so each daughter cell have the same number of chromosomes as the parent cell so both being diploid

In meiosis the chromosomes fold over DNA and are put in pairs, in the first division the pairs are split up evenly into two cells randomly (diploid still) but the the cells split the chromosomes in half in them creating four grneticly different haploid cells

This stadium can hold 100,000, or 1x10, people. The
Mekhanik [1.2K]

Answer:

1 x 10^13 stadiums will be needed in this scenario

Explanation:

We are told that

1 stadium holds = 1 × 10^5 people and

Number of iron atoms = 1 × 10^18 atoms

If the stadium carries an equivalent number of atoms as that of people.

We can infer that 1 stadium will carry 1 × 10^5 atoms.

The calculation to determine the number of stadiums would then be 1 × 10^18 divided by 10^5 atoms/stadium which was gotten by dividing the total number of atoms by the number of atoms per stadium.

Number of stadiums = Total number of atoms ÷ Number of atoms per stadium

= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium

= 1 × 10^13 Stadiums

This means that 1 × 10^18 atoms would occupy 1 × 10^13 stadiums

A client is diagnosed with peripheral arterial disease. A review of the client's chart shows an ankle-brachial index (ABI) on th
alex41 [277]

Answer:

The correct answer is option c.

Explanation:

The ABI or the ankle-brachial index examination refers to a noninvasive and brisk way to determine PAD or peripheral artery disease. The disease takes place when narrowed arteries diminish the flow of blood to the limbs. The condition can result in leg pain at the time of walking and enhances the chances of stroke and heart attack.  

On the basis of ABI, one can find that a healthy individual lacking arterial insufficiency exhibits an ABI of about 10. Those with an ABI of 0.95 to 0.5 shows minor to modest arterial insufficiency. The individuals with an ABI of less than 0.50 exhibits ischemic rest pain. Those with the loss of tissue show extreme ischemia and an ABI of 0.25 or less.
