Answer:

A scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. A scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.

In exocytosis,cells release material such as proteins like enzymes from within the cell into the extracellular space. Endocytosis is where a cell transports molecules such as proteins <span>into the cell. The complimentary and twined processes can be used for the transport of proteins as an example.</span>

in pea plants round seeds are dominant and wrinkled seeds are recessive. the cross rr x rr, what percentage of the offspring wil

In-s [12.5K]

Answer:

Explanation:

Round = Dominant

Wrinkled = recessive

Recessive = r

Dominant = R

homozygous dominant = RR

homozygous recessive = rr

Heterozygous= Rr

Since both seeds are homozygous recessive (rr)

In your punnet square, one lower case r will go on the top and the left side

r r

Something like that.

Go across your four boxes and you will end up with;

rr, rr

In order for it to be round, at least one box would need to have to be a heterozygous(Rr) or be a homozygous dominant.

The gravitational potential energy of Sara at the given height is 10594.8J.

Given the data in the question;

Mass of Sara; $m; = 60kg$

Distance from ground; $h = 18m$

Acceleration due to gravity; $g = 9.81m/s^2$

Gravitational potential energy; $U = \ ?$

<h3>Gravitational Potential Energy</h3>

Gravitational potential energy is the potential energy an object with mass posessses relative to another object with mass due to gravity.

It is expressed as;

$U = mgh$

Where m is mass, h is height and g is acceleration due to gravity.

To determine the gravitational potential energy of Sara, we substitute our given values into the expression above.

$U = mgh\\\\U = 60kg * 9.81m/s^2 * 18m\\\\U = 10594.8kgm^2/s^2\\\\U = 10594.8J$

Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.

What is the likelihood of a category 5 hurricane making landfall in Maryland?<br>

Hoochie [10]

Answer: Not likely

Explanation:

Hurricanes can be devastating if they make landfall in an area and even if they do not, can cause excessive rainfall that can lead to flooding in other areas. One of such areas is Maryland.

Even though Maryland has seen its fair share of effects from hurricanes, tropical storms and tropical depressions, there has not been a single storm making landfall at hurricane intensity in Maryland since the mid twentieth century. Hurricane Agnes for instance, caused the deaths of 19 people due to the floods it caused.
