George Beadle concluded that teosinte is the likely ancestor of maize (corn), even though the two plants appear very different.
Oliga [24]

Answer:

Option B

Explanation:

ALL options are as follows -

a. teosinte and maize can produce fertile hybrids.

b. teosinte and maize have similar chromosomes.

c. Both Teosinte and maize have naked, soft kernel.

d. Teosinte and maize can produce fertile hybrids

Solution

Beadle started working on maize genetics since 1962 after joining graduate school at Cornell University.  

During his research he found that the chromosomes of teosinte and maize possess higher similarity and also show signs of intercross ability of the two species and hence confirmed that wild teosinte is an ancestor of domesticated maize.  

He later concluded that there are only 4 to 5 genes that make these two species different from each other rest all is similar.

(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.
