Which one of the following is the correct statement about the respective animal(s)? 

  1. Donkey and horse should be considered one single species because they can successfully mate and produce an offspring.

  2. Donkey and horse are two different genuses.

  3. Mule is a separate species.

  4. Mule is neither a donkey nor a horse.

D Correct answer
Explanation

A mule is the sterile offspring of a male donkey and a female horse. It is not a separate species because it cannot reproduce with other mules to maintain a population.

A taxonomic group of closely related genera is known as?

  1. Species

  2. Order

  3. Family

  4. Class
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Species represents a distinct group of the population that really or most likely breed from close animals. This taxonomic class is segregated from other classes through the method of reproduction. It bears minimal taxonomic traits.
It includes individuals that inherit basic similarities.It can be differentiated from other closely connected species because of idiosyncratic morphological characteristics. Option A is the answer
Multiple choice biology ecology carbon cycling mineral coal carbon cycle

Which of the following is the largest reservoir of carbon?

  1. Soil

  2. Atmosphere

  3. Ocean

  4. Sedimentary rocks
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In the ocean, there are underwater sediments and sediment rocks of carbonate like in the form of limestone, dolomite etc. Thus, the correct answer is option C.

How does photosynthesis help to maintain the percentage of oxygen and carbon dioxide in the atmosphere?

  1. By giving off carbon dioxide and absorbing oxygen

  2. By giving off oxygen and absorbing carbon dioxide

  3. By releasing oxygen and carbon dioxide

  4. By absorbing oxygen and carbon dioxide.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

During photosynthesis, carbon dioxide is fixed to form carbohydrate by the dark reaction. The water molecules are broken down during the light reaction and release oxygen. Thus, the two process helps to maintain the balance of oxygen and carbon dioxide in the atmosphere.

So, the correct answer is option B.

Biochemical cycle with gaseous phase is

  1. Carbon

  2. Sodium

  3. Phosphorus

  4. Magnesium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbon is a gaseous cycle because it circulates through the atmosphere primarily as carbon dioxide. Elements like sodium, phosphorus, and magnesium are sedimentary cycles with no significant gaseous phase.

The number of possible enantiometric pairs that can be produced during monochorination of 2-methyl butane is:

  1. 2

  2. 3

  3. 4

  4. 1
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Monochlorination of 2-methylbutane can occur at four different carbon positions. The products formed at the chiral center (C2) result in a pair of enantiomers. The other positions do not create new chiral centers in this specific molecule, resulting in 2 enantiomeric pairs total.
