1. There are four major macromolecules found in nature; Carbohydrates, proteins, lipids and nucleic acid. The macromolecule that assists with the production of energy for immediate energy and glycogen storage (which is the storage of "energy" in the muscle) is carbohydrates.
2. The foods that should be selected here are food that are rich in carbohydrate. Examples of such food include Rice, cassava, yam and plantain.
3. To test for the presence of carbohydrate in the food sources chosen in (2) above, iodine test can be used. The choice of iodine test is because the food sources mentioned above contains complex carbohydrates. Few drops of a solution of iodine should be added to a sample of the food, if the colour of the iodine on the sample turns blue black, then that confirms the presence of complex carbohydrates in the food.

In humans the process of digestion begins in the mouth where food is chewed into small pieces by the teeth. The saliva helps by moving pieces these pieces around. These pieces are covered by bland,or spit. The saliva makes the food slippery so it's easier to blank.
Answer:
The saliva makes the food slippery so it's easier to SWALLOW.
Explanation:
Digestion of food begins from the mouth. When the food is chewed, it mixes with the saliva from the salivary gland and this makes the food slippery and easier to swallow. Once it is swallow it moved to pharynx to the oesophagus and down to the stomach where the stomach acid act on it. From there enzymes from the pancreases act on it to break it down and it is moved down to the small intestine where it is absorbed as nutrients and the undigested one move to the large intestine and form faeces.

What are cells that make up testis (imma need like. At least 2 sentences- 3 sentences pls)
Answer:
Seminiferous,Rete testis, Efferent ducts
Explanation:
Seminiferous tubules are coiled tubes that make up most of each testis. The cells and tissues in the tubules are responsible for spermatogenesis, which is the process of creating sperm.
After sperm is created in the seminiferous tubules, sperm cells travel toward the epididymis through the rete testis. The rete testis helps to mix sperm cells around in the fluid secreted by Sertoli cells. The body reabsorbs this fluid as sperm cells travel from the seminiferous tubules to the epididymis.
The efferent ducts are a series of tubes that join the rete testis to the epididymis. The epididymis stores sperm cells until they’re mature and ready for ejaculation.

whats the form of Stereoisomerism?
Answer:
In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. This contrasts with structural isomers, which share the same molecular formula, but the bond connections or their order differs. By definition, molecules that are stereoisomers of each other represent the same structural isomer.

Some solutes move freely across cell membranes, while other solutes require
assistance from special gates. Passive transport and active transport are methods of
moving solutes across cell membranes.
Which of the following accurately describes the difference between passive transport
and active transport?
A Passive transport can move molecules both in and out of a cell, but active transport
cannot.
B Passive transport works against a concentration gradient, but active transport does
not.
C Passive transport does not require energy, but active transport does.
D Passive transport requires carrier proteins, but active transport does not.
Answer:
the first one is F, the permeability. the second is C
Question 4: The permeability of the cell membrane determines the rate at which molecules enter a cell.
Question 5: The statement that describes the difference between passive and active transport is "Passive transport does not require energy, but active transport does"
CELL MEMBRANE:
The cell membrane is the organelle that bounds the cell and its component.The cell membrane is referred to as a semipermeable membrane because it selectively allows the passage of molecules in and out of the cell. However, the rate at which molecules enter a cell is determined by the permeability of the cell membrane. The cell membrane is permeable to some molecules but not permeable to others.CELLULAR TRANSPORT:
The transport of substances in and out a cell can be of two types namely: active transport and passive transport. Active transport is the type of transport that involves the use of energy in form of ATP. In active transport, substance move against a concentration gradient. On the other hand, passive transport does not require energy input because movement of substances occur down a gradient. Therefore, the statement that describes the difference between passive and active transport is "Passive transport does not require energy, but active transport does".Learn more at: https://brainly.com/question/18067330?referrer=searchResults

Explanation:
The cross over frequency between linked genes C and D is 40%; between A and D is 35%; between C and A is 5%; between A and E is 25%; and between E and D is 10%. Construct a linkage map of these 4 gense and show the distances between the adjacent genes.
Answer: The first line shows the Correct order of genes in the chromosome and the second and third lines show the distances between genes.
C ------------ A ---------------------------------- E -------------------- D (Correct order)
/-----5MU--//---------------25 MU-----------//---------10MU-----/ (Distances)
/------------------------------------40 MU ------------------------------/ (Total distance)
Explanation:
We need to know that 1% of recombination frequency = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products, one results in a recombinant one.
The recombination frequencies between two genes determine their distance in the chromosome, measured in map units. So, if we know the recombination frequencies, we can calculate distances between the four genes in the problem and we can figure the genes order out. This is:
Recombination frequencies:
1% of recombination frequency = 1 map unit (MU)
C-D = 40% = 40 MU
A-D = 35% = 35 MU
C-A = 5% = 5 MU
A-E = 25% = 25 MU
E-D = 10% = 10 MU
Now that we know the distances between pairs of genes, we need to figure out which is the correct order in the chromosome.
C and D are the genes with the biggest distance between them (40MU), which probably means they are in the extremes. The rest of the genes are in the middle.
C ------------------ (40MU) --------------------------------------- D
A is 5 MU apart from C and 35 MU apart from D, which means it is closer to C.
C------ (5MU)----A------------------------------(35 MU)-------D
E is 25 MU apart from A and only 10 MU apart from D, which means it is between A and D, and closer to D
C--------------------A------- (25 MU)---------E----(10MU)-----D
The sum of C-A distance + A-E distance + E-D distance equals the C-D distance. This is:
C-A 5MU + A-E 25MU + E-D 10MU = C-D 40 MU
5 + 25 + 10 = 40
In conclusion, the correct order of the genes in the chromosome is
C ------------ A ---------------------------------- E -------------------- D
/-----5MU--//---------------25 MU-----------//---------10MU-----/
/------------------------------------40 MU ------------------------------/
Explain how so many types of cells can be formed even though all the cells have the same DNA.
Because all of your cells in your body started off as single cells. That single cell then divided into multiple other cells. So it breaks down so it can help the entire body equally. In order for a cell to work 1,000 of these proteins need to be created.

Explain why scientists use shared
characteristics to make cladograms.
Answer:
Scientist use synapomophies, or shared derived characters, to define cladograms. For instance, mammary glands are a shared characteristic of mammals. All mammals and their oldest common ancestor, had or have mammary glands.Thus, if we are looking at an unidentified animal and trying to place it in a cladogram, if it has mammary glands we know it belongs in that branch. Cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny. A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors.
Explanation:
Answer:
Sample Response: Shared characteristics are features or qualities that organisms have in common with each other. They are used to make cladograms because they show the relationships among organisms. They can also show which organisms have a common ancestor.

In a cross between two mice that are heterozygous for agouti, black, color, and piebaldism, what is the probability that offspring will have solid black fur along with large patches of white fur? (Hint: Consider each gene separately; then use the multiplication rule. For more help getting started, see Hint 1.)
Answer:
9/256
Explanation:
According to Mendel's experiments the results for the heterozygous are in the ratio 3:1
As each gene is considered separately and the multiplication rule is used. Therefore the probability of getting a solid color would be 1/4 and black fur would be 3/4. Similarly the probability of getting the colored fur is 3/4 and getting a piebald( white patches) is 1/4
Then the combined probability is (1/4*3/4*1/4*3/4)= 9/256
