B. bronchi
C. arteries
D. veins
Answer: Option A
Explanation:
The exchange of the oxygen and carbon dioxide takes place in the lungs. The oxygen from the lungs are exchanged by the carbon dioxide between the alveoli and capillaries.
The oxygen from the lungs are carried away to various cells of the body and the carbon dioxide from the body cells are carried to the lungs for the process of exchange of gases.
Answer:
B. choanocytes
Explanation:
B
The structure formed by wrapping DNA around a histone core is called a nucleosome.
A section of DNA wrapped around core histoneproteins is termed a nucleosome. The protein and DNA complex inside the nucleus is called chromatin. This is a thread-like structure due to the formation of which DNA is condensed into a small volume.
The structure of chromatin appears to be like 'beads on a string under a microscope. The beads are the nucleosomes. The nucleosomes are small structures with a diameter of approximately 11 nm. Also, nucleosomes are known to be the fundamental subunits of chromatin.
In each nucleosome, a set of eight histone proteins are present. There are about two turns of DNA in each nucleosome around eight histone proteins. These histone proteins are known as histoneoctamer. There are two sets of each histone protein namely, H2A, H2B, H3, and H4.
Therefore, the structure formed by wrapping DNA around a histone core is called a nucleosome.

a. They can cross Yummious letus with a fungus to stimulate protein synthesis.
b. They can take mutant fungal DNA and insert it into Yummious letus
c. They can add DNA from Bigous moldkillae into the soil around Yummious letus.
d. They can insert the gene for the protein from plant species Bigous moldkillae into a chromosome in Yummious letus.
Answer:
The correct option is D) They can insert the gene for the protein from plant species Bigous moldkillae into a chromosome in Yummious letus.
Explanation:
Biotechnology can be described as the technology in which the genome of organisms are altered so that organisms with better qualities can be produced. In the scenario discussed in the question, techniques of biotechnology can be used to insert the fungus-killing gene of Bigous moldkillae into the genome of the Yunnious letus. In this way, the Yunnious letus species will become resistant to the fungal infections.
The crust is formed of basalt rocks that are dark in color and are rich in minerals and substances like silicon and magnesium is oceanic while the crust is formed of light-colored granite rocks that have full of substances like oxygen and silicon is continental. Plagioclase feldspar is frequently found in granitic continental crust and basaltic oceanic crust.
Plagioclase is a tectosilicate mineral that comes in the feldspar group.
It is usually white, or gray which is translucent.
It is a mineral which is most frequently found in both granitic continental crust and basaltic oceanic crust.
Thus, the answer is Plagioclase feldspar.
