Camouflage is an evolutionary adaptation that allows animals to blend into their surroundings, making it harder for predators to spot them or for them to ambush prey.

Multiple choice physics temperature and heat modes of heat transfer - conduction conduction heat and modes of heat transfer

Give reason : Birds puff up their feathers in winter 

  1. so that they can trap more air

  2. so that can develop charge

  3. cant say

  4. so that friction reduces
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Birds puff up their feathers in winter because by doing so they trap a large amount of air in their body which in turn acts as an insulator and does not allow the heat from their bodies to flow out

Multiple choice botany chromosomal basis of inheritance linkage and crossing over linkage and recombination genetics: inheritance

The blue green algae and bacteria contain.

  1. One linkage group

  2. Two linkage groups

  3. Three linkage groups

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

All the genes which are located on a single chromosome form one linkage group. The total number of linkage groups in an organism corresponds to the haploid number of chromosomes, i.e., to the number of chromosome pairs.

  • Most bacteria have a genome that consists of a single DNA molecule (i.e., one chromosome).
  • The blue-green algae is a cyanobacterium that possesses one chromosome.

So, the correct answer is 'One linkage group'.

Multiple choice evs interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

Consider the following four conditions and select correct pair about desert lizards.
(i) Burrowing in the soil to escape high temperature. 

(ii) Losing heat rapidly from the body during high temperature. 
(iii) Bask in the sun when the temperature is low. 
(iv) Insulating body due to the thick fatty dermis.

  1. i, iv

  2. i, ii

  3. iii, iv

  4. i, iii
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Desert lizards manage to keep their body temperature constant by behavioral means. They bask in sun and absorb heat when their body temperature drops but move into shades when ambient temperature starts increasing. So the correct option is " i,iii"

Multiple choice zoology infectious diseases cancer and aids hiv and aids immunity related disorders and problems

Which one of the following does not follow the central dogma of molecular biology

  1. HIV

  2. Pea

  3. Mucor

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

The central dogma of molecular biology states that genetic information flows from DNA to RNA to protein. HIV is a retrovirus that uses reverse transcriptase to convert its RNA genome into DNA, which violates the standard flow of information.

Multiple choice biology animal world oviparous and viviparous diversity and classification in animals adaptations in animals

................ keep the birds warm while flying at high altitudes.

  1. Beaks

  2. Claws

  3. Feathers

  4. Hollow bone
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Feathers are epidermal growths that form the distinctive outer covering on dinosaurs and birds. They provide insulation, the body temperature of most birds is maintained at around 40 C, feathers allow for flight. They may also be plucked to line the nest and provide insulation to the eggs and young. The individual feathers in the wings and tail play important roles in controlling flight.

So, the correct answer is 'Feathers'.

Multiple choice biology animal world oviparous and viviparous diversity and classification in animals adaptations in animals

Which of the following statements are incorrect among the options given below?

  1. Plants do not have mechanism to maintain internal temperature

  2. Polar bears going into hibernation during winter is an example of escape of area

  3. Desert lizard has physiological ability to regulate

  4. Success of mammals is largely due to their ability to maintain a constant body temperature
Reveal answer Fill a bubble to check yourself
B,C Correct answer
Explanation
  • For the regulation of body temperature, there is an internal mechanism called homeostasis, This regulates the internal body temperature in mammals but is absent in plants.
  • During winters the polar bears do not undergo hibernation, instead, they remain active. Their body temperature is maintained by the fur-coated on their body which protects them from extreme cold and snow.
  • Desert lizards are conformers (They cannot regulate their own body temperature and requires external factors like the sun).
  • So, the correct option is ' Polar bears going into hibernation during winter is an example of an escape of area and Desert lizard has a physiological ability to regulate'. 
Multiple choice biology animal world oviparous and viviparous diversity and classification in animals adaptations in animals

Desert lizard is an example of:

  1. Regulator

  2. Conformer

  3. Behavioral regulator

  4. Partial regulator
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Regulators are those animals that can regulate their body temperature by their own, according to the environment and their need while conformers are those animals that cannot regulate their body temperature and require sun to increase their body temperature. The conformers are also called cold-blooded animals. Some of the examples of conformers are desert lizards, fishes, snakes etc.

So, the correct option is 'Conformer'.

Multiple choice evs likes and dislikes genetics terminology similarities and dissimilarities in organisms features of human body and sign language

Which of the following human features can be same?

  1. Height

  2. Weight

  3. A and B

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

  • BMI takes into account both height and weight but not body composition.
  • Body mass index (BMI) is a common tool for deciding whether a person has an appropriate body weight.
  •  Human height and weight varies greatly between individuals and across populations for a variety of complex biological, genetic, and environmental factors, among others and can be same across the population sometimes. Hence, Height and Weight are human features that can be the same.
So, the correct answer is 'A and B'.
