In screech owls, red feathers are dominant over gray feathers. If two heterozygous red-feathered owls are mated, what percentage of their offspring would be expected to have red feathers
In screech owls, if two heterozygous red-feathered owls are mated, then about 75% of the offspring produced will be having red feathers.
What is a genetic cross?A genetic cross can be defined as the deliberate breeding of two different individuals or species which results in the formation of offspring that carry part of the genetic material of each of the parent. The parent organisms must be genetically compatible to each other and may also be from different varieties or the closely related species.
In screech owls, red feathers are dominant over gray feathers. This means that, red feather allele is dominant over gray and will mask its effect.
Therefore, about 75% of the offspring produced from a cross between two heterozygous red feathers owls would be expected to have red feathers.
The punnett square for this cross is attached with the answer.

After you’ve removed a loopful of broth culture from the culture tube, what’s your next step in preparing a smear?.
Given what we know, after you’ve removed a loopful of broth culture from the culture tube you should immediately apply a flame to the open end of the test tube.
Why would this be the next step?Once you have removed the loopful of broth culture from the tube, you should apply a flame to the end of the tube, this is of vital importance. The reason for this is to deny any other contaminants from entering or exiting the culture sample.
Therefore, we can confirm that after you’ve removed a loopful of broth culture from the culture tube you should immediately apply a flame to the open end of the test tube.

Explain why an organism with a similar volume but more spherical in shape would not be as efficient as a flatworm at exchanging substances with their environment.
Answer:
As the ratio gets smaller, it takes longer for items to diffuse.
Explanation:
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared.
When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but less area for that substance to actually enter the cell.
this is actually why cells divide. When they become too large and it takes too long for them to transport materials across the cell, they lose efficiency and divide in half to raise the surface area to volume ratio.

Which statement best explains why multicellular organisms have specialized cells?
O They must undergo cellular respiration to get energy needed to move and grow.
O They must replace dead cells with new ones.
O They must undergo photosynthesis to obtain energy needed for cellular respiration.
O They are made of cells that form tissues and organs that perform specialized functions.
Answer:
I think your answer would be D.
Explanation:
The tissues are not specialized. The organelles do not cooperate in order to perform the functions of living things. The majority of its cells do not come into contact with the outside world.
Multicellular organisms means the the organisms composed of more than one cells. These cells will differentiate to perform specialized functions.
Why multicellular organisms have specialized cells?According to level of organization, cell combine to form tissue, tissue group together to form organs, organs combine to form organ system and organ system work in coordination to form organism.
In multicellular organisms, each group of cells perform specialized functions.
Thus, option D is correct, i.e., they are made of cells that form tissues and organs that perform specialized function.

These rocks come straight from the interior of the Earth.
A liquid mass of silicate composition coming from the Earth's core erupts out of a volcano as lava.
Since this melted mass comes from the Earth's interior, its temperature is extremely high.
Lava begins to cool and solidify during its ascent to the Earth's surface.
Igneous rocks are produced by the cooling of magma when they get in touch with air.

why are breathing structures supposed to be thin
Answer:
A respiratory surface is covered with thin, moist epithelial cells that allow oxygen and carbon dioxide to exchange. Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.
