Animal Growth And Heredity Questions and Answers
- 1.
What is Direct Development?
- A.
All stage's of an organism's life
- B.
A threadlike strand of DNA inside the nucleus
- C.
The process that reduces the number of chromosomes
- D.
A kind of growth where the animal keeps the same body features as they grow
Correct Answer
D. A kind of growth where the animal keeps the same body features as they growExplanation
Direct development refers to a type of growth in which an animal maintains the same body features throughout its life stages. Unlike indirect development, where an organism undergoes significant changes in body structure during its lifecycle (such as a caterpillar transforming into a butterfly), direct development involves the animal growing larger while retaining its basic body form.Rate this question:

- 2.
Cells of an adult continue to divide after the adult has stopped growing in order to replace dead cells and repair the body system.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because cells in the adult body continue to divide even after the growth phase is complete. This division is necessary for the replacement of dead cells and to repair any damage or injuries to the body systems. This ongoing cell division ensures that the body is able to maintain its structure and function properly.Rate this question:

- 3.
_______ is the process of cell division.
- A.
Breeding
- B.
Budding
- C.
Metamorphosis
- D.
Mitosis
Correct Answer
D. MitosisExplanation
Mitosis is the correct answer because it refers to the process of cell division. During mitosis, a single cell divides into two identical daughter cells, each containing the same number of chromosomes as the parent cell. This process is essential for growth, repair, and reproduction in organisms. Breeding, budding, and metamorphosis are not processes of cell division, making them incorrect options.Rate this question:

_____________ are required in sexual reproduction. (Check all that apply)
- A.
Zygote
- B.
Chromosomes
- C.
Two parents
- D.
Reproductive system
Correct Answer(s)
C. Two parents
D. Reproductive systemExplanation
In sexual reproduction, two parents are required as they contribute genetic material to create offspring with unique traits. In some animals, one individual can produce both sperm and eggs although cross-fertilization is more common. The reproductive system is also necessary to facilitate the union of gametes from both parents and support the development of the zygote. Chromosomes are essential as they carry the genetic information that is passed down from the parents to the offspring. The zygote is formed when the sperm and egg fuse, initiating the development of a new individual.Rate this question:

Genes found on chromosomes contain the DNA codes for the inherited traits.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Genes are segments of DNA that contain the instructions for building and maintaining an organism. These genes are located on chromosomes, which are structures within the cell that carry genetic information. Therefore, it is true that genes found on chromosomes contain the DNA codes for the inherited traits.Rate this question:

What is a strong trait called?
- A.
Important trait
- B.
Main trait
- C.
Dominant trait
- D.
None of these
Correct Answer
C. Dominant traitExplanation
A strong trait is often referred to as a dominant trait. This means that the trait is more likely to be expressed in an individual's phenotype, even if only one copy of the gene responsible for the trait is present. Dominant traits tend to be expressed over recessive traits, which require two copies of the gene to be expressed. Therefore, the correct answer is "Dominant trait."Rate this question:

Mitosis produces __________ cells and meosis produces ___________ cells .
- A.
Body, reproductive
- B.
Dead, body
- C.
Reproductive, multi
- D.
Reproductive, body
Correct Answer
D. Reproductive, bodyExplanation
Mitosis is a type of cell division that produces two identical daughter cells, which are used for growth, repair, and maintenance of the body. Therefore, the first blank should be filled with "body" as mitosis produces body cells. On the other hand, meiosis is a type of cell division that produces four non-identical daughter cells, each with half the number of chromosomes as the parent cell. Meiosis is involved in the production of gametes (reproductive cells), such as sperm and eggs. Hence, the second blank should be filled with "reproductive" as meiosis produces reproductive cells.Rate this question:

_________ are threadlike strands of DNA inside the nucleus.
- A.
Chromosomes
- B.
Vessel
- C.
Cell
- D.
None of these
Correct Answer
A. ChromosomesExplanation
Chromosomes are threadlike strands of DNA that are found inside the nucleus of a cell. They contain the genetic information that is passed down from one generation to another. Chromosomes play a crucial role in the process of cell division and determining the traits and characteristics of an organism. They are made up of genes, which are segments of DNA that code for specific proteins. Therefore, chromosomes are the correct answer to the given question.Rate this question:

Most mammals can lay eggs.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because most mammals do not lay eggs. Mammals are characterized by giving birth to live young, not by laying eggs. The majority of mammals, including humans, give birth to live offspring through internal fertilization. Only a few species of mammals, such as monotremes (platypus and echidna), lay eggs. Therefore, the correct answer is false.Rate this question:

The 3 stages of incomplete metamorphosis are ____, ____, and ____.
- A.
Adult, eggs, nymph
- B.
Eggs, nymph, eggs
- C.
Eggs, nymph, adult
- D.
None of these
Correct Answer
C. Eggs, nympH, adultExplanation
In incomplete metamorphosis, the organism goes through three stages: eggs, nymph, and adult. This means that the organism starts as an egg, then hatches into a nymph, and finally develops into an adult. Therefore, the correct answer is "eggs, nymph, adult."Rate this question:
