(c) Name all the classes of Chordata which is warm-blooded (endothermic).
ddd [48]

The classes of chordata which are warm-blooded are birds and mammals.

Explanation:

Warm-blooded animals are those which can maintain their body temperature at a constant.  

These classes of chordates balance their internal body temperature with that of the outer environment. When the outer environment is cold, they increase their internal temperature by producing more heat; and when it is hot outside they reduce their internal temperature by cooling themselves.  

The food consumed by a warm-blooded animal fuels to maintain a constant body temperature and hence they require more food.  

Warm blooded animals cool themselves with the help of sweat glands.  

The skin and other parts like fur in birds help to keep the animals warm during winter. Birds also shed their fur in hot season to keep them light. Birds migrate to warm regions during winter.

These animals have high stamina and energy to survive environmental changes. They maintain their temperature through endothermy, homeothermy or tachymetabolism.

Whale living in water is the fish which is also warm blooded because it is a mammal.

Antagonsitic effect/interaction/response

In order to combat antiobiotic resistance, and to possibly enhance the activity of antibiotics, they are sometimes used in combinations during treatment. However, three possible responses or effects can manifest. 

First is antibiotic synergy, where the combined effect of the antibiotics enhances the activity/potency of the treatment compared to when the antibiotics are administered singly.

The effect is also distinguished from another type of response, which is additive effect, where the combined effect of the antibiotics is more or less equal to the combined activity/potency of each of the antibiotic when applied singly. Antibiotic synergy results in even greater enhancement of the activity of the combined antibiotics compared to additive effect. 

Lastly, there is the antagonistic effect or response, where the combined effect of the antibiotics results in the weakening of the potencies of the antibiotics relative to the combined (additive effect) potencies of each of the antibiotics.

Glucose is generally phagostimulatory (stimulates eating) for animals. The observation that cockroach populations exposed to poi
xxMikexx [17]

The correct answer is:

A. Will have a intermediate trait 3. Glucose aversion is a genetically-determined incompletely dominant trait

B. Will refuse glucose 2. Glucose aversion is a genetically-determined dominant trait

C. Have a mix of traits depending on experience 4. Glucose aversion is a learned behavior

D. Will accept glucose 1. Glucose aversion is a genetically-determined recessive trait

If we put it simple and say that for example glucose aversion is genetically determinated, with the genotype AA and eating glucose with the genotype aa. The offspring will have Aa genotype (heterozygous). Depending on which phenotype is expressed in heterozygous we can conclude whether the trait is dominant or recessive or due to earned behavior.

The solutions in the two arms of this U-tube are separated by a membrane that is permeable to water and glucose but not to sucro
bazaltina [42]

Answer:

Intially the glucose concentration is levelled and then the liquid level in side A will rise.

Explanation:

  • Initially the liquid ob both sides are in isotonic condition.
  • The membrane is permeable to glucose so glucose will diffuse from higher concentration (2 M) to lower concentration (1 M) until the concentration become equal (1.5 M) on both sides.
  • Know, the Side A have 2 M sucrose and 1.5 M glucose and  side B have 1 M glucose and 1 M sucrose.
  • The side A will become hypertonic and side B will become hypotonic and water will start moving from side B to side A.
