Chart that tracks which members of a family have a particular trait
- A.
Pedigree
- B.
Enfamil
- C.
Chromosome
Correct Answer
A. PedigreeExplanation
A pedigree is a chart that tracks which members of a family have a particular trait. It is commonly used in genetics to study the inheritance patterns of traits or genetic disorders within a family. By mapping out the presence or absence of a trait across multiple generations, a pedigree can provide valuable information about the mode of inheritance and help identify individuals who may be at risk for inheriting or passing on a specific trait or disorder.Rate this question:

If a parent has type A blood, the other parent has type B bloodwhat are the possible blood types of the baby?
- A.
AB-
- B.
A
- C.
B
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
If one parent has type A blood and the other parent has type B blood, the possible blood types of the baby could be AB-, A, or B. This is because the baby can inherit either the A allele from the type A parent, the B allele from the type B parent, or both alleles (AB) if both parents pass on their respective alleles. Therefore, all of the above blood types are possible for the baby.Rate this question:

Where are sex linked jeans located
- A.
Mitochondria
- B.
Chromosomes
- C.
DNA
Correct Answer
B. ChromosomesExplanation
Sex-linked genes are located on chromosomes. Chromosomes are thread-like structures found in the nucleus of cells that carry genetic information. They contain genes, which are segments of DNA that determine specific traits. Sex-linked genes are genes that are located on the sex chromosomes, specifically the X and Y chromosomes. These genes can be responsible for traits or disorders that are more commonly seen in one sex than the other. Therefore, it is correct to say that sex-linked genes are located on chromosomes.Rate this question:

Put these in order from simple to complex in an ecosystemorganism, ecosystem, population, community
Correct Answer
organism, population, community, ecosystem, organism population community ecosystem, organism,population,community,ecosystemExplanation
In an ecosystem, the basic unit is an organism, which refers to an individual living thing. Multiple organisms of the same species make up a population, which is the next level of organization. Populations of different species interacting with each other form a community. Finally, all the communities in a specific area, along with the non-living factors, make up an ecosystem. Therefore, the correct order from simple to complex in an ecosystem is organism, population, community, ecosystem.Rate this question:

Competition can be reduced when there is enough.....
- A.
Oxygen
- B.
Food
- C.
Water
Correct Answer
B. FoodExplanation
Competition can be reduced when there is enough food because when there is an abundance of food, individuals have access to the necessary nutrients and energy to survive and thrive. This reduces the need for individuals to compete with each other for limited resources, as there is enough food available for everyone. With ample food supply, individuals can focus on other aspects of survival and reproduction, leading to a decrease in competition for food resources.Rate this question:

What advantage does specialized cells have over others?
- A.
Special nucleus
- B.
Unique function
- C.
Unique membrane
Correct Answer
B. Unique functionExplanation
Specialized cells have an advantage over others because they have a unique function. This means that they are specifically designed to perform a specific task or carry out a particular function in the body. This specialization allows them to be more efficient and effective in performing their designated role, compared to cells that have a more general or generic function. By having a unique function, specialized cells can contribute to the overall functioning and health of the organism in a more specialized and targeted manner.Rate this question:

Tiny hairlike structure that help cells move
- A.
Cilia
- B.
Flagella
Correct Answer
A. CiliaExplanation
Cilia are tiny hairlike structures that help cells move. They are found on the surface of many types of cells and are involved in various functions such as moving fluid, sensing the environment, and facilitating the movement of reproductive cells. Cilia have a characteristic structure and motion that enables them to beat in a coordinated manner, propelling the cell or moving substances across the cell surface. Flagella, on the other hand, are similar to cilia but are longer and typically found singly or in pairs, helping cells move in a whip-like motion.Rate this question:

Has a whip like tail, cells have only one maybe 2
- A.
Cilia
- B.
Flagella
Correct Answer
B. FlagellaExplanation
The correct answer is flagella because flagella are whip-like tails that certain cells have. These flagella help the cells in movement and propulsion. Unlike cilia, which are shorter and more numerous, cells usually have only one or maybe two flagella. Therefore, flagella is the most suitable answer based on the given information.Rate this question:

Male sex cell
- A.
Sperm
- B.
Egg
Correct Answer
A. SpermExplanation
Sperm is the correct answer because it is the male sex cell responsible for fertilization. Sperm is produced in the testes and is released during ejaculation. It has a tail that helps it swim towards the egg for fertilization to occur. On the other hand, an egg is the female sex cell and is produced in the ovaries. Fertilization occurs when a sperm penetrates the egg, resulting in the formation of a zygote.Rate this question:

Female sex cell
- A.
Ovary
- B.
Egg
- C.
Sperm
Correct Answer
B. EggExplanation
