............... reproduce in the host .

  1. humans

  2. bacteria

  3. plants

  4. virus
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Viruses are obligate intracellular parasites, meaning they require a living host cell to replicate and reproduce.

Multiple choice

The two main problems that effect reproduction are:

  1. Heat detection and ovarian cancer

  2. Heat detection and cold stress

  3. Heat detection and conception rates

  4. Heat detection and heat stress
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Reproductive efficiency is primarily limited by the ability to accurately detect when a cow is in heat and the biological success rate of fertilization (conception).

Multiple choice

What are the two types of ovarian cysts?

  1. follicular and luteal

  2. ovum and luteal

  3. follicular and ovum

  4. follicular and horn
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ovarian cysts in cattle are categorized based on their structure and function as either follicular cysts (thin-walled, produce estrogen) or luteal cysts (thick-walled, produce progesterone).

Multiple choice botany modes of reproduction different modes of reproduction sexual and asexual reproduction lifespan, reproduction and variation

The process of regeneration of new individual of the same kind is called as

  1. Metabolism

  2. Differentiation

  3. Reproduction

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Reproduction refers to the process by which new individual organisms (offspring) are produced from their parent.

Some animals like Planaria reproduce by regeneration. It is a type of asexual reproduction in which an organism is capable of regrowing certain body parts or the whole organism from different pieces.
So, the correct option is 'Reproduction'.

The production of offsprings by sexual or asexual process is called as

  1. Division

  2. Growth

  3. Reproduction

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Reproduction is the process by which organisms produce offspring that are similar to themselves.

  • Reproduction can be either sexual or asexual.
  • Asexual reproduction involves only a single organism while sexual reproduction involves gamete formation from two different sexes and their fusion.
  • So, the correct option is 'Reproduction'.

The process of production of closely resembled young one is called as

  1. Reproduction

  2. Division

  3. Growth

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Cell Division results in two or more daughter cells.
  • Growth is the irreversible increase in the dry mass of an organism. It is brought about by an increase in cell size or number.
  • Reproduction results in production of closely resembling young ones.
  • So, the correct option is 'Reproduction'.

The process of propagation of new individual from the existing one is called as

  1. Fertilization

  2. Syngamy

  3. Reproduction

  4. Propagation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Reproduction refers to the production or propogation of new individuals by an organism. 
  • Syngamy of fertilisation refers to the fusion of gametes which may or may not be similar.
  • So, the correct option is 'Reproduction'.

Multiple choice

Which statement describes all living things?

  1. They must reproduce sexually.

  2. They are composed of one or more cells.

  3. They are capable of making their own food.

  4. They have organ systems to carry out the processes of life.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

According to cell theory, all living organisms are composed of one or more cells. Not all living things reproduce sexually, make their own food, or have complex organ systems.
