Answer:
C
Explanation:
The crayfish is a relatively large specimen, even the mouthparts. Since you are dissecting the mouthparts, you need a 3D view: you should use the dissecting microscope.
Answer:
constitutive mutations
Explanation:
Constitutive mutations -
They are the strains which uninterruptedly make proteins , and therefore , can lead to excess of protiens and the process is very difficult or nearly impossible to stop , is known as the process of Constitutive mutations .
One of the example of this process of Constitutive mutations is ,
The strain with lac operon mutation which can even results in th etranscription of the lac genes .
Hence , from the statement of the question ,the correct term is Constitutive mutations .
The answer to this question is letter B. Convection.
<span>>Mantle's convection is thought to make up about eighty percent of the internal heat flow to the surface, while the remainder originates in the crust.
</span><span>>The main means of heat transfer is convection. This process requires that the substance can behave like a "fluid", and the earth's mantle does.</span>
Answer:
The correct answer will be option-A
Explanation:
In the pedigree analysis, the description of a trait help shows the relation of a trait linked to a gene.
The pedigree analysis is usually used to determine the heredity of a disease in a family which has been described in the question also as
1. The trait is rare and present in both sexes- this shows that it is independent of sex chromosomes and since is rare is recessive.
2. A consanguineous mating- mating between close relative which result in autosomal recessive trait as the genes for the trait must be present on both the parents which happen only when they are closely related.
Thus, option-A is the correct answer.
