Answer:

Cleavage

Explanation:

Toughness is the resistance of a solid to breakage. The tougher a solid is, the less likely it would succumb to breakage of any form.

Hardness is very similar to toughness and it describes how unyielding a sold is to pressure or force of any form.

Cleavage on the other hand describes the tendency or ability of a solid to spilt or be broken along a specified plane of weakness. When such a solid is hit hard, they show some fracturing directions which represents weaknesses in their lattice structures or crystal forms. Most solids have cleavage directions in them.

Katyanochek1 [597]

Answer:

The correct answer is - 2n = 41 chromosomes.

Explanation:

It is given that the cat has a diploid chromosome number of 38 while the rabbit has a diploid number of 44 chromosomes and if they form a hybrid then their expected chromosome number in somatic cells would be -

Cat (2n=38) produces haploid gametes with 19 chromosomes (n-19).

Rabbit (2n=44) produces haploid gametes with 22 chromosomes(n=22)

19+22= 41 chromosomes in the particular hybrid as half number of chromosomes come from each parent.

lions [1.4K]

Answer:

Hemoglobin rainier differ from normal hemoglobin with respect to oxygen affinity.

Explanation:

Hemoglobin is one of the most significant protein of Red Blood Cell containing heme(that contain Fe2+ which is coordinated with four porphyrine rings) and globin protein.

  Hemoglobin exist in two state one is tensed state or deoxy hemoglobin that have less affinity for oxygen, the other state is relaxed state or oxy hemoglobin that has high affinity for oxygen.

              In hemoglobin rainer the formation of new di sulfide bond prevent the formation of ion pairs that normally stabilize the T state as a result T state get unstable and this unstable T state is converted to R state to achieve the stability of hemoglobin structure.

           The R or relaxed state of hemoglobin has high oxygen affinity for oxygen.
