A mature cell divides into two, and so on. The new cell grows in size.
- A.
Placentals
- B.
Fragmentation
- C.
Oviparous
- D.
Fission or cell division
Correct Answer
D. Fission or cell divisionExplanation
The given statement describes the process of cell division, specifically fission. Fission is a type of cell division where a single cell divides into two identical daughter cells. This process allows for the growth and multiplication of cells. As the mature cell divides, each new cell grows in size, leading to an increase in the overall number of cells. Therefore, fission or cell division is the correct answer.Rate this question:

A new offspring simply grows from the body of a mother animal. It breaks off and later becomes independent.
- A.
Budding
- B.
Regeneration
- C.
Oviparous
- D.
Fission or cell division
Correct Answer
A. BuddingExplanation
Budding is the correct answer because it refers to a form of asexual reproduction where a new organism develops as an outgrowth or bud from the body of the parent organism. This bud eventually breaks off and becomes an independent organism. This process is commonly observed in organisms like yeast, hydra, and some plants.Rate this question:

Animals that give birth to young alive
- A.
Marsupials
- B.
Viviparous
- C.
Oviparous
- D.
Fission or cell division
Correct Answer
B. ViviparousExplanation
Viviparous refers to animals that give birth to live young, as opposed to laying eggs. This means that the offspring develop inside the mother's body and are nourished through a placenta or a similar structure. Marsupials, on the other hand, give birth to relatively undeveloped young that continue to develop in a pouch. Oviparous animals lay eggs, which hatch outside the mother's body. Fission or cell division does not pertain to the topic of animals giving birth to young alive.Rate this question:

Babies are completed or developed inside the female organism.
- A.
Placental animals
- B.
Marsupials
- C.
Monotremes
- D.
None of these
Correct Answer
A. Placental animalsExplanation
Placental animals are the correct answer because they are the only group of animals in which babies develop and are completed inside the female organism. In placental animals, the fetus is nourished and protected by the placenta, which allows for a longer and more advanced development compared to other groups of animals such as marsupials and monotremes. Marsupials give birth to relatively undeveloped young that then continue to develop and grow in the mother's pouch, while monotremes lay eggs and their young hatch outside the female's body. Therefore, neither marsupials nor monotremes fit the statement that babies are completed or developed inside the female organism.Rate this question:

- B.
Marsupials
- C.
Monotremes
- D.
None of these
Correct Answer
C. MonotremesExplanation
Monotremes are a group of egg-laying mammals that include the platypus and echidna. Unlike placental animals and marsupials, monotremes lay eggs instead of giving birth to live young. Therefore, the correct answer is monotremes.Rate this question:

In EXTERNAL fertilization, where do the egg and sperm cells unite?
- A.
Environment
- B.
Ovary
- C.
Body or womb
- D.
Parents
Correct Answer
A. EnvironmentExplanation
In external fertilization, the egg and sperm cells unite in the environment. This means that the fertilization process occurs outside of the bodies of the organisms involved. This is common in many aquatic organisms, where the female releases her eggs into the water and the male releases his sperm nearby. The sperm then swims to the eggs, allowing fertilization to occur in the surrounding water. This method of fertilization is advantageous as it increases the chances of successful fertilization due to the large number of eggs and sperm released.Rate this question:

In INTERNAL fertilization, where do the egg and sperm cells unite?
- A.
Environment
- B.
Ovary
- C.
Body or womb
- D.
Parents
Correct Answer
C. Body or wombExplanation
In internal fertilization, the egg and sperm cells unite inside the body or womb. This is because internal fertilization refers to the process where the sperm is deposited inside the female reproductive system, allowing the sperm to reach and fertilize the egg within the female's body. This is in contrast to external fertilization, where the sperm and egg meet outside the body, typically in water.Rate this question:

The correct answer includes kangaroo, wombat, wallaby, and opossums. These animals are all marsupials, which means they give birth to relatively undeveloped young and carry them in a pouch. Marsupials are primarily found in Australia and nearby islands, and they have unique reproductive adaptations compared to other mammals. Kangaroos, wombats, wallabies, and opossums are all examples of marsupials that exhibit this pouch-carrying behavior.Rate this question:

G. Echidna anteaterExplanation
The correct answer is platypus and echidna anteater. Monotremes are a group of mammals that lay eggs instead of giving birth to live young. The platypus and echidna are the only two living species of monotremes. The platypus is known for its unique appearance, with a duck-like bill, webbed feet, and the ability to produce venom. The echidna, also known as the spiny anteater, has spines on its back and a long snout for feeding on ants and termites. Both of these animals are found in Australia and are considered primitive mammals due to their egg-laying reproduction.Rate this question:

Part of an animal that is detached becomes a whole animal.
- A.
Budding
- B.
Regeneration
- C.
Fragmentation
- D.
Fission or cell division
Correct Answer
C. FragmentationExplanation
Fragmentation is the correct answer because it refers to the process where a part of an animal becomes detached and develops into a whole new organism. This process is observed in certain animals, such as starfish, where if a part of their body is detached, it can regenerate and grow into a complete individual. This is different from other options like budding, regeneration, and fission or cell division, as they involve different mechanisms of reproduction or growth.Rate this question:

The kind of reproduction undergone by AMOEBA AND BACTERIA
- A.
Budding
- B.
Regeneration
- C.
Fragmentation
- D.
Fission or cell division
Correct Answer
D. Fission or cell divisionExplanation
Amoeba and bacteria undergo fission or cell division as a form of reproduction. Fission is a type of asexual reproduction where the organism divides into two or more equal-sized offspring. In amoeba, fission occurs by binary fission, where the cell divides into two daughter cells. Similarly, in bacteria, fission occurs by binary fission or multiple fission, where the parent cell divides into two or multiple daughter cells. This process allows for rapid reproduction and population growth in both amoeba and bacteria.Rate this question:

Regeneration
- C.
Fragmentation
- D.
Fission or cell division
Correct Answer
D. Fission or cell divisionExplanation
Flatworms undergo a type of reproduction called fission or cell division. In this process, the flatworm's body divides into two or more parts, each of which can develop into a new individual. This allows the flatworm to reproduce asexually, without the need for a mate. Fission is a common method of reproduction in many species of flatworms and is an efficient way for them to increase their population.Rate this question:
