The factors that determine how much the motion of the air molecules will change are:
.The rate of diffusion which is affected by the concentration gradient, .membrane permeability.temperature.pressureThe movement of substances from a region of higher concentration to a region of lower concentration is called diffusion of particles. This phenomenon is very important in cellular transport in plants.
The rate of diffusion is affected by 4 factors namely:.concentration gradient: Diffusion takes place when there is a difference between the concentrations of a substance across a barrier. Diffusion stops when the concentrations of the substance on either side of the barrier become equal.
.membrane permeability: Diffusion rate increases as membrane permeability increases.
.temperature and pressure is paramount in the diffusion of gases as gases diffuse from a region of higher partial pressure to a region of lower partial pressure. Same as in terms of temperature.

The user needs to drag the slider bar in an upwards direction in order to completely melt away a body layer when in the dissection study area.
True or False
Answer:
False
Explanation:
During the dissection study the body is kept in laying position so that the scientist can easily perform experiments. The body is kept in laying position not in upward position. The body in upward position will have gravitational effect on the fluids and the body layer will not melt.
In a population of 239 pea plants in equilibrium, 47 individuals have white petals, while the rest have purple petals. Color is controlled by a single gene with two alleles.

Why did you not see any chloroplasts in the onion epidermal cells, unlike in the Elodea (Anacharis) cells?
-Chloroplasts in onion cells are hidden by the large central vacuole.
-The part of the onion viewed under the microscope grows underground.
-The purpose of chloroplasts is to make the plant green but onions are not green.
-Chloroplasts are organelles that absorb sunlight energy and perform photosynthesis.
-Plant parts that grow underground are not exposed to sunlight.
-Onions had chloroplasts before they were picked from the ground but the chloroplasts dried up and disappeared after being exposed to the sunlight.
-Onions are not plants and therefore do not have chloroplasts.
-Plant parts that are not exposed to sunlight cannot do photosynthesis.

What happens if you drop some type of liquid on a cable such as a phone charger? Can you get hurt? Can you still use it?
Kind of a weird question lol
It really just depends. If the liquid got in any crevices it might not work. If it wasn't plugged in, no you cannot get hurt. But I've had chargers that I spilled water on and they still work fine, but again, it depends. Like if there's a tear in the cord that liquid got in, then no it probably won't work anymore.

viruses are not fit into broadest taxanomic system because:
they are not cells
they do not reproduce their own
they do not respond to stimuli.

A scientist is researching two different traits in an insect: body texture and color. Smooth body (B) is dominant to bumpy body (b), and gray (G) is dominant to white (g). A BbGg and a bbgg insect mate and produce the following 480 offspring: Phenotype Number of Offspring Smooth, gray 119 Bumpy, white 117 Smooth, white 123 Bumpy, gray 121 What type of inheritance is displayed from these offspring
Answer:
Independent assortment
Explanation:
The type of inheritance displayed by the offspring is a simple independent assortment inheritance according to Mendelian law.
The result of crossing BbGg and bbgg is as follows (see the attached image)
4 BbGg smooth and gray
4 Bbgg smooth and white
4 bbGg bumpy and gray
4 bbgg bumpy and white
The phenotype ratio from the cross is 1:1:1:1 as far as the independent assortment is concerned.
Now, looking at the population of each phenotype from the cross
Smooth, gray 119
Smooth, white 123
Bumpy, gray 121
Bumpy, white 117
119:123:121:117 is approximately equal to 1:1:1:1.
Hence, the cross agrees with Mendel's law of independent assortment of genes.
Why are phospholipids of the plasma membrane oriented such that their heads are at the membrane surfaces and their tails are buried in the interior of the membrane?
Answer:
The plasma membrane is semi-permeable. The reason for this is because of the orientation of the phospholipids. The heads at the surface are hydrophilic so they face the water. The tails are hydrophobic so they face away from the water.
Explanation:
The phospholipids of the plasma membrane are oriented such that their heads are at the membrane surfaces and their tails are buried in the interior of the membrane - due to the fact that phospholipids have hydrophobic tails and hydrophilic heads.
Phospholipids consist of fatty acids and alcohol in the plasma membrane are arranged in two layers, known as the phospholipid bilayer. It has a hydrophobic or water-hating tail and a hydrophilic or water-loving head.
it has a head and two tails.As the tails are hydrophobic so, face the inside, away from the water.As the heads are hydrophilic so face outwardHeads are towards intracellular and extracellular fluid.Tails are meet the inner layerThus, the correct answer is - due to two layers of hydrophobic tails and hydrophilic heads.

Answer:
DNA with the shortest strand will travel longer than DNA with the longer strand. In electrophoresis, the electricity will cause the DNA to move from one side of the gel to the other side. Shorter DNA strand will have a lower resistance to move in that gel so it can move further.
Explanation:
DNA with the shortest strand will travel longer than DNA with the longer strand. In electrophoresis, the electricity will cause the DNA to move from one side of the gel to the other side. Shorter DNA strand will have a lower resistance to move in that gel so it can move further.
The smallest strand of DNA will move farther than the longest strand. DNA will travel from one side of the gel to the other during electrophoresis as a result of the voltage.
What is DNA?A shorter DNA strand will pass through the gel with less resistance, allowing it to move farther.
The smallest strand of DNA will move farther than the longest strand. DNA will travel from one side of the gel to the other during electrophoresis as a result of the voltage.
A shorter DNA strand will pass through the gel with less resistance, allowing it to move farther. The publication of On the Origin of Species in 1859, Darwin has typically eclipsed Wallace.
