If retinal detachment occurs in the macula lutea, one can predict that there would be a significant loss of _____

Mendel crossed two plants that were heterozygous for purple flower color. Which genotypes could he have used to represent the cr

Stella [2.4K]

The answer is Pp Pp.

If we imagine that plant has two alleles for the trait and if P represents dominant allele, and p represents recessive allele, then genotypes are:
PP - dominant homozygous, which contains both dominant alleles
pp - recessive homozygous, which contains both recessive alleles
<span>Pp - heterozygous, which contains both dominant and recessive alleles</span>

How do cells make more ATP when they run out? <br><br> HELP PLZ

mihalych1998 [28]

Answer:

When a cell is very low on ATP, it will start squeezing more ATP out of ADP molecules by converting them to ATP and AMP (ADP + ADP → ATP + AMP).

Tony wanted to see if he could make the roots of a plant grow up instead of down. After several tries, he found that the roots a

7nadin3 [17]

Answer:

Plants stem grow against the gravity while roots grow towards the gravity and this prices is known as the geotropism or gravitism explains that the roots grow toward the direction of the gravity pull termed as positive geotropism.

Auxin is a hormone that acts at the bottom of the cell and have different function in roots and stems as in stems it promotes the elongation of the cell against gravity while in roots it is promotes the elongation of the cell towards the gravity.

(20 points) [URGENT] give a hypothesis on how the mass of potato chips is expected to change in each solution

lbvjy [14]

I predict that the potato in the lowest sugar solution

(water) will gain the most mass through osmosis, whereas the 80% sugar

concentration will lose the most mass through osmosis. I predict this

because I think that the potato chips will try to gain and lose water

between the two sides of its cell wall in order to reach an

equilibrium between them because the 80% sugar solution has a high

amount of sugar molecules, which can not diffuse through the membrane,

I think that the potato will lose water in order to make the solution

on the outside of its membrane equal to the water concentration on the

inside thus losing mass. I also predict that the other

concentrations (60%, 40%, and 20%) will lose mass, but in lower

numbers compared to the 80% sugar solution (the lower the

concentration, the higher the mass). However, since the distilled

water carries no sugar molecules, I think that the potato chip will

gain water to create a balance between the two sides of the cell wall,

making it gain mass.

One group of students did an experiment to study the movement of ocean water. The steps of the experiment are listed below.

Delvig [45]

Answer:

Explanation:

The lamp and the ice bag were at the same place.

Sounds like the experiment was intended to show on a small scale ocean currents from the poles to the equator and back to the poles. The bag of ice would simulate the cold at the poles while the lamp would simulate the heat provided by the sun near the equator. With that in mind, let's look at the possible flaws and see what is likely.

Not enough ink was added.

* If you can see the ink, then there's enough ink. So this isn't the correct choice.

Not enough water was taken.

* Possibility there wasn't enough volume of water to setup a current, but not too likely since the baking dish was filled. So let's look further.

The dish was too small for the experiment.

* Same as above. It might be this, but there's something more likely.

The lamp and the ice bag were at the same place.

* This sounds like a winner. In the real world, the poles are cold and the equator gets more sunlight. So there's a temperature gradient. In the described setup, both the heat sink (the bag of ice) and the heat source (the lamp) were at the same location.
