Answer:
Nervous tissue is made up of neurons that receive and conduct impulses. Neurons are highly specialised for being stimulated and then transmitting the stimulus very rapidly from one place to another within the body. Impulses are the passage of electrical activity along the axon of a nerve cell.
Tt x Tt gives 3 Tall(Tt, Tt, TT) and 1 Short(tt) so the probability would be 75 percent
<h2>Answer:</h2>
Soil bacteria are mainly involved in four steps in nitrogen cycle.
- Nitrogen fixation
- Nitrification
- Ammonification
- Denitrification
<h3>Explanation:</h3>
- First of all atmospheric nitrogen is fixed by soil bacteria (N2 to NH3/ NH4+, NO3-)
- Nitrification: The conversion of ammonium to nitrate is performed primarily by soil-living bacteria and other nitrifying bacteria (NH3 to NO3-)
- When a plant or animal dies or an animal expels waste, the initial form of nitrogen is organic. Bacteria or fungi convert the organic nitrogen within the remains back into ammonium (NH+4), a process called ammonification.
- Denitrification is the reduction of nitrates back into nitrogen gas (N2), completing the nitrogen cycle. This process is performed by bacterial species such as Pseudomonas and Clostridium in anaerobic conditions.

Answer:
Embryology: the study of similarities in embryos of organisms to find common connections
Developmental biology: the study of life cycles of organisms to find common
Molecular biology: the analysis and comparison of DNA to better understand relationships between species
comparative anatomy: the study of the anatomy of an organism to explain evolutionary similarity
Explanation:
Embryology can be described as the branch of biology in which studies about the sex cells, the process of fertilization and the development of the fetus or embryo are made. The similarities between the embryos show evolutionary history among different organisms.
Developmental biology can be described as the branch of biology in which studies are made about the processes of growth and developmental procedures about organisms. Organisms belonging to different groups can also show developmental similarities if they have a common ancestor.
Molecular biology is the branch of biology which is related to the study of life on molecular level. At this level, similarities between the genome of organisms can be checked for evolutionary histories.
Comparative anatomy: It is the branch of biology in which organisms are studies based on the similarities and differences in their structures.
