In human beings, after fertilisation, the structure which gets embedded in the wall of uterus is

biology for the continuity of generation fertilization in human being fertilization in humans human fertilization

  1. Ovum

  2. Embryo

  3. Blastocyst

  4. Zygote

Show answer
Correct Option: C
Explanation:

After fertilization zygote is formed. Zygote start moving towards uterus and initial development takes place. Zygote enters the uterus on 3rd day in morula stage and later develops into blastocyst that implants in uterus wall. Thus, the correct answer is option C.

Poultry keepers should maintain proper .......... of poultry house regularly.

biology animals in daily life animal breeding animal husbandry and its importance introduction to animal husbandry

  1. Cleaning 

  2. Sanitation 

  3. Both A and B

  4. Light

Show answer
Correct Option: C
Explanation:

In poultry farming, poultry birds are raised, managed protected from diseases as they are used as food material for humans. For egg and broiler production care is taken to avoid mortality and to maintain feathering and carcass quality. Poultry keepers should maintain proper cleaning and sanitation of poultry house regularly. It is necessary for them to be careful against diseases.

Thus, the correct answer is option C.

Bird flu is also known as

  1. Avian influenza.

  2. Hepatitis A.

  3. Hepatitis B.

  4. Yellow fever.

Show answer
Correct Option: A
Explanation:

Avian influenza caused by infection with avian (bird) influenza (flu) Type A viruses. These viruses occur naturally among wild aquatic birds worldwide and infect domestic poultry and other bird and animal species. 

So, the correct answer is 'Avian influenza'

Broilers are :

  1. Egg laying females.

  2. Young birds reared for meat.

  3. Birds raised for breeding.

  4. Birds raised for both eggs and meat.

Show answer
Correct Option: B
Explanation:
Day old chicks in a littered barn, with a controlled atmosphere for humidity and temperature control.
chickens are reared for meat are called broilers or broiler chickens. they originate from the jungle fowl of the Indian subcontinent. The broiler Industry has grown due to consumer demand for affordable poultry meat.

Brooding period of chicken is ________

biology animals in daily life animal breeding animal husbandry and its importance introduction to animal husbandry

  1. First two weeks

  2. First four weeks

  3. First 3-8 weeks

  4. First 8-10 weeks

Show answer
Correct Option: C
Explanation:
Technically, brooding is defined as the period from hatching until supplemental heat is no longer needed. And for most people this means chicks are kept indoors under heat for 3 to 8 weeks depending on breed and time of year you brood. They need to be kept warm enough in a temperature controlled environment.

Which of the following ions has a regulatory role in internal movements?

biology animal tissue muscle tissue structure of protein muscle tissues

  1. Calcium

  2. Magnesium

  3. Iron

  4. Zinc

Show answer
Correct Option: A
Explanation:
  • Sarcoplasmic reticulum is similar to endoplasmic reticulum present in other cells. It is present in sarcoplasm (cytoplasm of the muscle cell) of the muscle fiber (muscle cell).
  • The main function of the Sarcoplasmic reticulum is to store calcium ions (Ca2+).
  • When nerve signal reaches the neuromuscular junction it triggers the release of calcium from sarcoplasmic reticulum which in turn facilitates muscle contraction by binding to troponin. thus causing tropomyosin to shift from the face of the actin filament to which myosin heads need to bind to produce a contraction.
  • Hence Calcium ions have a regulatory role in internal movements.
  • So, the correct answer is 'Calcium'.

All the following are examples of connective tissue except _______________.

biology animal tissue muscle tissue structure of protein muscle tissues

  1. Tendons

  2. Ligaments

  3. Muscle

  4. Adipose tissue

Show answer
Correct Option: C
Explanation:

Connective tissue serves a connecting function. It supports and binds other tissues in the body. This tissue typically has cells scattered throughout an extracellular matrix of fibrous proteins and glycoproteins attached to a basement membrane. The primary elements of connective tissue include a ground substance, fibres, and cells. Adipose tissue is a type of specialised connective tissue and the ligaments and the tendons belong to the dense type of connective tissue while the muscle belongs to another class of tissues namely muscle tissue which are different from the connective tissue.
So, the correct answer is 'Muscle'.

A muscle is rich in 

biology animal tissue muscle tissue structure of protein muscle tissues

  1. Fat

  2. Protein

  3. Vitamins

  4. Carbohydrate

Show answer
Correct Option: B
Explanation:

A muscle is rich in protein. The muscle cells contain protein filaments of actin and myosin. Actin is a thin filament and myosin is a thick filament. These protein filaments slide past one another to produce contraction. This results in change in length and shape of the cell.

Thus, the correct answer is 'Protein.'

Movement in body are brought about by?

biology animal tissue muscle tissue structure of protein muscle tissues

  1. Muscular tissue

  2. Epithelial tissue

  3. Bones

  4. Tendon and ligaments

Show answer
Correct Option: A
Explanation:

The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body & the maintenance of the body posture & body position.

So, the correct option is 'Muscular tissue'.

Contractile proteins are found in_________________.

biology animal tissue muscle tissue structure of protein muscle tissues

  1. Bones

  2. Blood

  3. Muscles

  4. Cartilage

Show answer
Correct Option: C
Explanation:

From all the above options, only muscle has a property of contraction. Muscle possess contractile proteins named, acitn and myosin on myofibrils. Hence, option C is correct.
