Answer:
Organnelle
Ribosomes
Nucleus
Archaeabacteria
Phospholipid bilayer
Lipases
Explanation:
1. Organnelles are specialized structures in a cell designed to perform a particular function that will make the cell normal e.g. ribosome, Chloroplast, mitochondrion are examples of organnelles.
2. The Rough Endoplasmic Reticulum (RER) is one of the two endomembranous systems in the cell. It is characterized by its rough appearance which occurs as a result of ribosomes attached to its surface. This attachment of ribosomes makes its function related to protein synthesis.
3. Nucleus is a membrane bound organnelle found only in EUKARYOTIC cells. It houses the genetic material (DNA) of a cell and acts as the brain by directing all of the cellular activity of that cell.
4. Archaeabacteria is one of the six kingdoms in the hierarchical classification of living organisms. They contain unicellular and prokaryotic organisms that are uniquely characterized by their ability to survive extreme conditions e.g high temperature.
5. The plasma membrane is an outer covering that bounds the cells of both Prokaryotic and eukaryotic organisms. According to the fluid mosaic model that describes the structure of the cell membrane, it contains a phospholipid layer that confines its selective permeability upon it i.e. ability to control what goes in and out of the cell. This is due to the amphipathic nature of the phospholipid i.e. contains an hydrophobic and hydrophilic region.
6. Lipases are enzymes that are involved specifically in the breakdown of lipids and fat molecules into fatty acids and glycerol.
The phenotype ratio would be 25% each for widow's peak and freckles, widow's peak without freckles, straight hairline with freckles, and straight hairline without freckles.
<h3>Dihybrid crossing</h3>
Genotype of the heterozygous parent: HhFf
Genotype of the other parent = hhff
Crossing the two parents:
HhFf = 1/4 = Widow's peak, freckles
Hhff = 1/4 = Widow's peak, no freckles
hhFf = 1/4 = straight hairline, freckles
hhff = 1/4 = straight hairline, no freckles.

Plants give off oxygen (that we breathe)and breathe in our carbon dioxide that we exhale
Answer: Lotion
The type of preparation that must be patted onto the skin rather
than rubbed in is lotion. The reason why it should be patted is to prevent increase
circulation and itching. Lotions are water base and for external use only to
soothe or protect the skin from dryness.
The bald eagle and the black bear are tetrapods, which means that they both have four limbs along with the digits. This shows that they both are the descendants of the four-limbed ancestors. However, the limbs of the bear and the bald eagle have different functions. The forelimbs of both these organisms serves different purpose. Hence, their limbs are homologous organs. The homologous organs are those which have the same ancestry but the functions are different.
