Multiple choice biology animals in daily life earthworm - reproductive system reproduction in earthworm introduction to reproduction poultry farming food from animals

Protein of yolk is

  1. Casein and phosphovitin

  2. Lecithin and lipovitellin

  3. Phosphovitin and lipovitellin

  4. Casein and lecithin
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The different yolk's protein has distinct roles. Phosvitins are important in sequestering calcium, iron and other cations for the developing embryo. Phosvitins are one of the most phosphorylated (10%) proteins in nature, the high concentration of phosphate groups providing efficient metal-binding sites in clusters. Lipovitellins are involved in lipid and metal storage, and contain a heterogeneous mixture of about 16%  noncovalently bound lipid, most being phospholipid. Lipovitellin-1 contains two chains, LV1N and LV1C. Hence, option C is correct.

Carefully read the following information to answer the question -


An egg farmer is experimenting with different feed rations with the aim of increasing his production whilst reducing the cost of the feed per egg produced. The data from the two feeding experiments are given below.

Experiment 1

Protein concentration in feed (%) 10 11 12 13 14 15 16
Total vitamin level (mg/kg) 100 100 100 100 100 100 100
Cost of feed ration per 100 hens per day 6.00 7.00 7.50 8.00 8.50 8.75 9.00
Number of eggs per 100 hens per day 70 70 75 80 85 80 80

Experiment 2

Protein concentration in feed (%) 14 14 14 14 14 14 14
Total vitamin level (mg/kg) 50 75 100 125 150 175 200
cost of feed ration per 100 hens per day 8.00 8.25 8.50 8.75 9.00 9.25 9.50
Number of eggs per 100 hens per day 70 80 85 90 95 95 95


Which feed composition gives the least cost per egg produced?

  1. Protein concentration (%) - 16; Total vitamin level (mg/kg) - 100

  2. Protein concentration (%) - 14; Total vitamin level (mg/kg) - 50

  3. Protein concentration (%) - 14; Total vitamin level (mg/kg) - 100

  4. Protein concentration (%) - 14; Total vitamin level (mg/kg) - 150
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In Experiment 1-At protein concentration 16% vitamin level 100, the cost of feed is 9.00 and the number of egg produced is 80 per 100 hens

In experiment 2 - At protein concentration 14%, vitamin level 150, the cost of feed is 9.00 and the number of eggs produced is 95, an increase of 15 per 100 hens.
So, the correct answer is 'Protein concentration (%) - 14; Total vitamin level (mg/kg) - 150'

Multiple choice biology animals in daily life introduction to reproduction poultry farming food from animals

Read the following statements regarding poultry farm management.
(i) Poultry birds include chicken, ducks, turkey and geese.
(ii) Brooder house should be crowd-free, rain proof and protected from predators.
(iii) The most common egg-type variety used for commercial production throughout the world is single comb white leghorn and its various strains.
(iv) Approximately 14 to 16 hours of light including daylight are required for optimum egg production.
Which of the above statements are correct?

  1. (iii) and (iv)

  2. (i), (ii) and (iii)

  3. (i), (iii) and (iv)

  4. (i), (ii), (iii) and (iv)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All the statements given above regarding poultry farm management are correct . Poultry farm includes chickens, ducks, turkey and geese. Brooder house are typically wooden movable structures heated enclosure by electric for raising baby poultry. It is crowd free , rainproof and protected against predators . This will led to higher rate of egg production.  The most common type of egg variety used for commercial production are comes from Leghorn which requires a photoperiod of 16 hours for optimum egg production . Reduction in photoperiod leads to reduce egg yield. 

So, the correct option is 'Option D' .

Number of eggs per 100 hens per day 70 80 85 90 95 95 95


What are the independent variables in each of the two experiments?

  1. Experiment 1 - Maximum daily egg production; Experiment 2 - Maximum daily egg production

  2. Experiment 1 - Protein concentration in the feed; Experiment 2 - Total vitamin level in the feed

  3. Experiment 1 - Total vitamin level in the feed; Experiment 2 - Protein concentration in feed

  4. Experiment 1 - Cost of feed ration per egg produced; Experiment 2 -Cost of feed ration per egg produced
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In experiment 1 the protein concentration is controlled or changed. So as to check the effect on cost of feed ration and number of eggs produced. Therefore it an independent variable

In experiment 2 total vitamin level in the feed is controlled or changed. So as to check the effect on cost of feed ration and number of egg produced. Therefore it is an independent variable.
So, the correct answer is 'Experiment 1 - Protein concentration in the feed; Experiment 2 - Total vitamin level in the feed'

Multiple choice biology animals in daily life introduction to reproduction poultry farming food from animals

The chances of contracting bird flu from a properly cooked (above $100^0C$) chicken and egg are

  1. very high

  2. high

  3. moderate

  4. none.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Chicken and other poultry products are safe to eat if cooked properly. While cooking poultry to 70 degree celsius , it kills the H5N1 virus which causes bird flu. Therefore, it is recommended to cook meat above 74 degree celsius to kill all food borne pathogens. 

So, the correct option is 'Option D' .

  5. All of the above
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Eggs are an important and well-balanced source of essential nutrients. Bird eggs consist of a protective eggshell, albumen (egg white), and vitellus (egg yolk). Yolk of egg consists of 50% of water, 9% lecithin, 16% other proteins which includes albumin, provitellin and vitellin and 23% fats, 0.3% carbohydrates and 1.7% minerals. 

Therefore, the correct answer is option E.
