Biological transmission differs from mechanical transmission in that biological transmission option B: involves reproduction of a pathogen in an arthropod vector prior to transmission.
When a pathogen reproduces inside a biological vector that spreads it from one host to another, it is said to have undergone biological transmission. The primary carriers of biological transmission are arthropods.
The fundamental distinction between mechanical and biological transmission is that during mechanical transmission, agents are simply transferred from an infected host or contaminated substrate to a susceptible host. During biological transmission, the agent develops and/or propagates within the vector.

Answer:
1. Methionine, Glycine, Tyrosine, Isoleucine, Stop
2. 5, circle AUG, GGC, UAC, AUC, UGA
3. There will be 5 amino acids because we have 5 codons.
Explanation:
For this first question, we will need a codon chart, such as the picture I put up.
To find the amino acids with this, we will be using first, the first circle with the 4 big bold letters. for example we will use amino acid AUG.
Find A on the first circle. Then we will move down to the slightly less bold letters. find U.
Now, on the last set of letters, find G and the amino acid it is paired with. We got Methionine.
2. This will explain it probably, if not lmk and I'll go in depth.
A codon is any 3 letters (nucleotides) from either DNA or RNA that creates amino acids.
3. You need 3 codons to create 1 amino acid.
If we have 5 codons represented to us, we will as a result get 5 amino acids.
Hope this helped :)
Sort the variables of these three studies based on whether they are independent or dependent variables.
Study 1: the effect of light on flowering patterns of plants
Study 2: the effect of penicillin on the growth of E. coli
Study 3: the effect of progesterone on the ovulation of rats
Independent variables (IV) always cause an effect on the dependent variables (DV) and on results. 1) IV: Light, DV: flowering patterns. 2) IV: Penicillin, DV: E. coli growth. 3) IV: Progesterone, DV: Ovulation.
What are dependent and independent variables?
While conducting an experiment, several variables might influence the results.
Independent variables are those in which the researcher is interested and wants to know its effect on another variable. These independent variables are the ones that influence other variables and the experiment results.
The dependent variable is the other one in which the researcher is interested. This is the one affected by the independent variable, so the researcher wants to know how it changes according to the changes of the independent variable.
Controlled or constant variables are all the remaining variables that might affect the results, but the researcher is not interested in their effect. To avoid their effect on the dependent variable, they must be constant.

9. Is the condition in this pedigree inherited as a recessive or a dominant trait?
Answer: Recessive trait.
Explanation:
First generation:
In the first generation of the pedigree, the female is affected, while the male is not affected. Thus, the female must have at least one copy of the disease gene, while the male may or may not be a carrier.
Second generation:
They mate to give a normal female progeny. This female progeny has two X chromosomes, one from each parent. The female mates with a normal male and one of their sons are affected by the condition. This leads us to believe that the female was a carrier, and so was the male, and thus, the son has one affected gene from each parent, making him homozygous recessive for this condition.

what is metabolism?
the chemical processes that occur within a living organism in order to maintain life.
B-complex vitamins: These help metabolize carbohydrates, fats, and proteins, activating stored energy instead of letting it turn to fat. Niacin, vitamin B-6, and iron: This impressive trio increases your body's production of the amino acid L-carnitine to help burn fat.
Metabolism can be conveniently divided into two categories:
Catabolism - the breakdown of molecules to obtain energy
Anabolism - the synthesis of all compounds needed by the cells
Metabolism is closely linked to nutrition and the availability of nutrients. Bioenergetics is a term that describes the biochemical or metabolic pathways by which the cell ultimately obtains energy. Energy formation is one of the vital components of metabolism.

You wish to investigate how exercise affects the rate of cellular respiration. You decide to squeeze a ball for 5 minutes and around 3 minutes you begin to experience a burning sensation and fatigue. This means your muscles are beginning to run out of oxygen. What process is causing the burning in your muscles?
During an exercise, the process that is causing the burning in your muscles is the production of lactic acid in anaerobic respiration.
What is the effect of exercise on cellular respiration?Exercise refers to any activity that involves planned, structured, and repetitive bodily movements that are performed in order to maintain or improve the physical fitness of the body.
During exercise, the rate of cellular respiration increases, and similarly the rate of breathing increases.
At a point during the exercise, where the rate of oxygen consumption by the muscles exceeds the rate at which it is replenished during breathing, the cells of the muscles switch from aerobic respiration to anaerobic respiration.
During anaerobic respiration in the muscle cells, lactic acid is produced. The production of lactic acid in the muscles results in a burning sensation in the muscles as well as producing feelings of fatigue.

What is a strain of rice?Due to agricultural laws that prohibit the keeping of seeds from harvests and the planting of plants of a different genetic make or made by a different company.
You need to locate a pesticide that your plants are resistant to, find each one of them individually, and pluck them, or treat your entire garden with a pesticide that would kill all of your plants but not the resistant variety.

What are some example of an animal organs? Plant organs?
Animals have organs including the stomach, liver, lungs, and heart. Plants have two different kinds of organs: stems and leaves. Organ systems are collections of organs in higher organisms.
Organ systems are a set of organs working together to maintain good biological performance; organisms are living creatures generated by an ordered collection of systems. Organs are a group of tissues that come together to form a complex structure with a special function. The vegetative and reproductive organs of plants can be distinguished. The root, stem, and leaf are vegetative plant parts, whereas the flower, seed, and fruit are reproductive. The reproductive organs are necessary for reproduction, but the vegetative organs are crucial for sustaining a plant's existence (they carry out key tasks like photosynthesis).
In light of this, we may affirm that animals have organs such as the stomach, liver, lungs, and heart. Both stems and leaves are various types of organs in plants.

Large biomolecules as well as macromolecules known as proteins are made up of one or more extended chains of amino acid residues. Among the many tasks that proteins carry out in living things are catalysing metabolic processes, replicating DNA, reacting to stimuli, giving cells and organisms structure, and moving molecules from one place to another. The primary way that proteins differ from one another is in the order of their amino acids, which is determined by the nucleotide sequence of their genes and typically causes a protein to fold into a particular 3D structure that controls its activity.

What is Cellular respiration?Cellular respiration is the process which involves the oxidation of glucose molecules in the mitochondria of cell. It results into formation of ATP molecules.
The first stage of cellular respiration occurs in the cytoplasm which is known as glycolysis. This is the step where glucose molecules are broken down into smaller molecules. A small amount of energy is also released in this process. The second stage occurs in the mitochondria of cell which is citric acid cycle. This is the step where the small molecules combine with oxygen to produce water, carbon dioxide, and a large amount of energy. The third stage is known as Oxidative phosphorylation.
