The monomer unit of a protein contains?
The following genotypes of two independently assorting autosomal genes determine coat color in rats:
A—B—(gray); A—bb (yellow); aaB—(black); aabb (cream)
A third gene pair on a separate autosome determines whether or not any color will be produced. The CC and Cc genotypes allow color according to the expression of the A and B alleles. However, the cc genotype results in albino rats regardless of the A and B alleles present. Determine the F1 phenotypic ratio of the following crosses:
a. AAbbCC x aaBBcc
b. AaBBcc x AABbcc

three frogs jumped a total of 115 centimeters how far could each frog have jumped
Answer:
38.33 repeating
Explanation:
If the total was 115 centimeter all together and there were 3 frogs than you would want to divide the number by 3
115 centimeters divided by 3 is 38.33 repeating
if it is rounded just 38.3
or rounded to the nearest whole number it will just be 38

Over time, three types of cells derived from this single-celled animal have emerged with specialized functions and they interact as a multicellular organism.
Type 1: Launches the toxin-loaded vesicles. Non-motile
Type 2: Detects the toxin, moves, and hunts the prey.
Type 3: Engulfs the bacteria, breaks them down, and stores the parts. Non-motile
Required:
What organelles do each type have?
Answer:
Golgi bodies, endoplasmic reticulum and lysosomes.
Explanation:
Many vesicles are formed in the Golgi bodies and the endoplasmic reticulum, that is responsible for the transportation of materials from one part of the cell to another. Endoplasmic reticulum is the organelle that launches the toxin-loaded vesicles or in other words it is responsible for detoxification i. e. removal of toxic substances from the cell. Lysosomes is the organelle that act against the microorganisms such as bacteria , virus etc.

Describe the relationship among cells,tissues,organs,and organ systems in the human body .HELP
Answer:
Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
Explanation:
Answer:
Cells make up tissues, tissues make up organs, and organs make up organ systems.
Explanation:
The cell is a fundamental component of all organisms. A group of cells that have the same structure and function make up a tissue. There are four types of tissues in our body: muscular, connective, nerve, and epithelial. Several types of tissue connect into an organ. The organs collectivley make an organ system. The 12 systems in the body are nervous, digestive, cardiovascular, muscular, skeletal, endocrine, urinary, immune, integumentary, respiratory, excretory, and reproductive.

How do volcanic eruptions create rock?
Answer:
Once the Magma has cooled of it will turn into hard solid rock (or if you put cold water on it)
It has also created our different islands that we have today because of volcanoes.
Explanation:
Hope that helps
Answer:
magma is sometimes pushed up toward the surface, notably during volcanic eruptions. As it cools, the magma solidifies in the form of magmatic rocks such as basalt. So the rocks of Earth's crust are constantly being transformed as part of the geological cycle that lasts millions of years.
