Answer:
Embryology
Explanation:
Comparative Embryology is the field of embryology. It deals with the study and comparision of the development, morphology, anatomy, physiology and genetic make of embryos belonging to different species. It also help in determining the evolutionary relatedness of the embryos of the previously existing species and present day organisms on the basis of the similarities and differences in the embryo features. All embryos pass through the stage of few to multiple celled zygotes. The differentiation of the zygote results in the clump of cells called as morulas then into hollow balls of cells called as blastulas. The differentiation of blastula leads to the creation of organs of the body.
The specific subset of these reactions that break down nutrients in food can be
described as _____________.
(a) metabolic.
(b) catabolic.
(c) anabolic.
(d) biosynthetic.
Answer:
(B) Catabolic.
Explanation:
The metabolism refers to the chemical reactions which are used by the organisms to sustain their life therefore metabolism is considered a characteristic feature of the living organisms.
The metabolism involves either the formation of a molecule from the smaller subunits or monomer through a process known as anabolism and other involves the breakdown of the larger molecule into smaller subunits through catabolism.
In the given question, the breakdown of the food particle which is usually the complex biomolecules is broken down into simpler subunits through a catabolic reaction. The smaller subunits of molecules are easily absorbed ad then utilised by the body.
Thus, Option-B is the correct answer.
Soft body parts are well preserved as fossils.
A cast fossil leaves a hollow space once occupied by a dead organism.
Vertebrate fossils are more common than invertebrate fossils.
Answer:
D
Explanation:
I took the test
B. Pure Air Filtering System (PAFS).
C. Biological Identification and Screening Filter (BISF).
B) 25%
C) 40%
D) 50%
Answer: The correct answer is 25%.
Black color (B) of horse is a dominant trait over brown (b) color, which is a recessive trait. As we know that dominant gene masks the expression of recessive gene, therefore brown horse color will only be produced in the genpotype bb.
On the other hand, there are two possible genotypes for black horse color that is BB and Bb.
As per the question, parental genotypes are Bb and Bb. When they are crossed, they will produce 25 % foal with brown color (bb).
