Answers

The cardiovascular system focuses more on pumping blood all throughout the parts of the body which mean the heart, capillaries, veins, and arteries are all involved in this. The Respiratory System is all about the gas exchange that is happening in your body which involves the lungs, oral and nasal cavities.

How many chromosomes would be found in an allopolyploid plant if its parents had diploid numbers of 4 and 6 respectively?

Answers

How many chromosomes would be found in an allopolyploid plant if its parents had diploid numbers of 4 and 6 respectively?

Diploid number of 10

Diploid number of 5

Haploid number of 12

Haploid number of 5

Answer:

Diploid number of 5

Explanation:

Gametes are formed by meiosis and have a haploid chromosome number. The parent with diploid chromosome number 4 would form gametes with haploid chromosome number 2. Similarly, the parent with diploid chromosome number 6 will form gametes having haploid chromosome number 3. The fusion of these gametes will result in a zygote having a diploid chromosome number 2 + 3 = 5. The fusion of haploid male gamete and haploid female gamete produces a zygote with diploid chromosome number.

What is a nonnative animal that moves into a new place?

Answers

Answer:

Invasive species

Explanation:

Any organism that enters a habitat where it does not belong is an invasive species. There are many plants that have been brought from other countries, and sometimes they take root in the new habitat.

The same thing with animals and migration patterns, if a species moves to a new habitat it is known as an invasive species.

The danger with this phenomenon is that sometimes the invasive species will compete with the natural occuring wildlife.

Nonnative species that move to a new habitat are called invasive species.

Write “$6,188 for 82 shares of stock” as a unit rate. Round to the nearest hundredth, if necessary. A. $13.25/share B. $69.24/share C. $80.92/share D. $75.46/share

Answers

Answer:

Option D is correct.

Unit rate = $75.46/ share

Explanation:

Unit rate defined as the rate are expressed as a quantity 1, such as 3 feet per second or 8 miles per hour, they are called unit rates.

Given the statement: $6,188 for 82 shares of stock.

⇒Number of share = 82

$\text{Unit rate per share} = \frac{\text{Cost}}{\text{Number of share}}$

Substitute the given values we get;

$\text{Unit rate per share} = (6,188)/(82) = \$75.4634146$

Therefore, the unit rate (nearest to hundredth place) is, $75.46/ share

$6,188/82=75.4634146 so if you round that to the nearest hundredth you get $75.46(C)

When proteins help transport molecules in and out of the cell, it is called _____.passive diffusion
facilitated diffusion
active transport
endocytosis and exocytosis

Answers

Answer: The correct answer for the blank is-

facilitated diffusion and

active transport.

Facilitated diffusion is a type of passive transport (transport of solute from high area of concentration to lower area of concentration) that requires transport protein ( which work as transporters or channels for the transport of solute).

Active transport also requires transport proteins/ carrier proteins (which work as pump) to drive the transport of solutes against the concentration gradient. This process utilizes energy (obtained from hydrolysis of ATP) for the transport because solute move from high concentration to an area where their concentration is less.

When proteins help transport molecules in and out of the cell it is called active transport. Hope this helped :)
