The three organelles that are most involved in protein synthesis include: Nucleus, Ribosomes and Endoplasmic reticulum (ER).
What is protein synthesis and its significance?The protein synthesis is the formation of polypeptide chain from amino acids. It takes place in two stages of transcription and translation. Transcription is the transfer of genetic instructions from DNA to mRNA in the cell nucleus. It includes three steps: initiation, elongation, and termination. Translation is formation of protein from mRNA.
Proteins are largest, complex molecules that play many important roles in the body. They perform most of their work inside the cell and are necessary for the structure, function and regulation of body tissues and organs
What is needed for protein synthesis?Several essential substances must be present for protein synthesis, including the 20 amino-acids that make up proteins. Another essential component is a set of enzymes that work in this process. DNA and another form of nucleic acid called ribonucleic acid (RNA) are also essential.

A:GGCCUUAA
B:AATTCCGG
C:GGCCTTAA
D:AAUUCCGG
Answer:
D.) AAUUCCGG
Explanation:
RNA does not contain Thymine (T), instead, Adenine (A) pairs with Uracil (U). S0, complementary base pairs from DNA to RNA are A-U, T-A, G-C, and C-G. Using this fact, the complementary strand of mRNA should be AAUUCCGG.
3. can be triggered by airborne substances, foods or common bacteria and viruses
6. spasms can cause wheezing
8. excess mucus in the body
3. Airborne diseases are illnesses spread by tiny pathogens in the air. These can be bacteria, fungi, or viruses, but they are all transmitted through airborne contact. In most cases, an airborne disease is contracted when someone breathes in infected air.
6. If you have a respiratory problem, such as asthma, these muscles can contract and narrow your airway. When that happens, it's called a bronchial spasm, or a bronchospasm. During a bronchial spasm, breathing becomes more difficult. You may find yourself wheezing as you try to catch your breath.
8. What causes excessive mucus? Smoking or exposure to an irritant in the air may cause you to produce more mucus than usual. If the mucus is clear, you might have allergies. Other conditions that could cause excess mucus include bronchitis, chronic obstructive pulmonary disease, and cystic fibrosis.

There are fewer species in temperate regions because the number of trees per hectare is lower than in tropical rainforests.
What is deciduous forests and tropical rainforests ?Due to the trees in tropical deciduous forests losing their leaves in the dry season and growing new ones in the monsoon, these forests are also known as monsoon forests.
A deciduous forest is distinguished by its deciduous trees and plants, which lose their leaves every year, typically in the winter. Since the plants' height and shape vary, forests are typically very dense. Deciduous refers to plants and trees that have a tendency to fall, from which the name derives.
The tropics, or between latitudes of 23.5°N (the Tropic of Cancer) and 23.5°S (the Tropic of Capricorn), is where tropical rainforests are primarily found.

The muscles of the thigh is divided into three compartments: anterior compartment, medial compartment and posterior compartment. Function of anterior compartment muscles is to extend lower limb at knee joint.
How are thigh muscles and knee related?The medial thigh muscles allows for adduction of the leg. Weak adductor muscles can cause knee instability and increase the risk of an adductor strain. Medial thigh muscles protect important neurovascular structures as they pass from the proximal hip joint to knee and lower leg
Weak thigh muscles are common cause of runner's knee, which is a treatable cause of anterior knee pain. Weak thigh muscles allow kneecap to move sideways and rub abnormally against thighbone.

generally, will natural selection result in an increase or decrease in variation? why does this happen and how, in theory, will it affect evolution in the future?
Natural selection decreases the genetic variation in populations by selecting for or against a specific gene or gene combination
How does natural selection cause variation?Genetic variations that alter gene activity introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, then genetic variation is more likely to be passed on to the next generation, which is known as natural selection.
As natural selection is a mechanism of evolution, organisms that are more adapted to environment are more likely to survive and pass on the genes that aided their success. Therefore, this process causes species to change and diverge over time.

Cell membranes are made of lipids and carbohydrates.
Cell membranes are rigid and protect the cell.
Cell membranes form barriers around the cell.
Answer:
Part of the cell membrane is a phospholipid bilayer,
Explanation:
Cell membranes are composed of proteins and lipids. Since they are made up of mostly lipids, only certain substances can move through. Phospholipids are the most abundant type of lipid found in the membrane. Phospholipids are made up of two layers, the outer and inner layers., made of two layers of phospholipid molecules. However, the cell membrane also contains other macromolecules like membrane proteins, and carbohydrates. Therefore, we can say that the cell membrane is made of a phospholipid bilayer, but it is not only made of it.
Alculate NEP before the outbreak and identify the most appropriate conclusion about whether the forest was a carbon sink or a carbon source. Calculate NEP before the outbreak and identify the most appropriate conclusion about whether the forest was a carbon sink or a carbon source. Before the outbreak, the forest was a carbon sink because NEP was less than 0. Before the outbreak, the forest was a carbon sink because NEP was greater than 0. Before the outbreak, the forest was a carbon source because NEP was less than 0. Before the outbreak, the forest was a carbon source because NEP was greater than 0
Because NEP was higher than 0 before to the outbreak, the forest served as a carbon sink.
What is Net ecosystem production (NEP)?The total amount of organic carbon in an ecosystem that is available for storage, export as organic carbon, or non biological oxidation to carbon dioxide through fire or ultraviolet oxidation is represented by net ecosystem production (NEP), which is defined as the difference between gross primary production and total ecosystem respiration.
