Answer:
The earth developed seasons during the Late Precambrian eon.
Explanation:
<span>the correct answer is B. the information that decides the characteristics of all organisms are contained in their nucleic acids. Nucleics acids are DNA and RNA. DNA have genes that code for proteins which are responsible for the structural and functional characteristics of organisms. DNA is transcribed into RNA and RNA is translated to proteins. Therefore information that is in these nucleic acids determines all the characteristics of organisms</span>
Answer:
Bb, Db
, Bd and Dd
Explanation:
When a cross between two parents (having certain trait) is carried out , they share their alleles with each other to produce offspring with new traits. These offspring have gentically different allele combination as compared to their parents. A genetic cross can be represented by a punnet square (as given below)
The cross between two parents with genotype "BD" and "bd" will result into the following offspring -
B D
b Bb Db
d Bd Dd
Answer:a. Rods and cones, bipolar cells, ganglion cells, optic nerve
Explanation:
The bipolar cells are present in between the rod and cone and ganglion cells.
The function of bipolar cells is to transmit signals from the photoreceptors (rod and cones cells) to the ganglion cells. The signals are then transferred to the brain via optic nerves where visual image is created.
Answer:
The correct answer is D; ATP hydrolysis inside mitochondria
Explanation:
Proteins imports brought into the matrix of mitochondria are normally taken up from the cytosol in practically less time after their discharge from ribosomes. Transportation of protein imports into the matrix is driven by energy which is supplied by:
- <u>ATP hydrolysis outside the mitochondra: </u>this occurs in the first step of translocation process. ATP hydrolysis drives the release of newly synthesized polypeptides from the hsp70 group of chaperone proteins.
- <u>an electrochemical proton gradient</u> across the inner mitochondrial membrane maintained by electron transport process in the inner membrane.
- <u>ATP hydrolysis in the matrix</u>: Hsp70 chaperone proteins in the matrix space likewise have a job in the translocation procedure, and they are the third point in the import procedure at which ATP is expended.
