Answer:
A given quantity of solute dissolves faster when it is ground into small particles than if it is in the form of a large chunk because more surface area is exposed.
Answer:
A photon of light hits chlorophyll, causing an electron to be energized.
The free electron travels through the electron transport chain, and the energy of the electron is used to pump hydrogen ions into the thylakoid space, transferring the energy into the electrochemical gradient.
Answer:
CRISPR-Cas9 is a unique technology that enables geneticists and medical researchers to edit parts of the genome? by removing, adding or altering sections of the DNA? sequence. It is currently the simplest, most versatile and precise method of genetic manipulation and is therefore causing a buzz in the science world.

septum is present between the two ventricles and separates the oxygenated and deoxygenated blood. hence if it gets ruptured then the two blood will mix up. thanks
Answer: Question 1 answer: Skin cells continually replicate
Explanation: The cells in the superficial or upper layers of skin, known as the epidermis, are constantly replacing themselves. This process of renewal is basically exfoliation (shedding) of the epidermis. But the deeper layers of skin, called the dermis, do not go through this cellular turnover and so do not replace themselves.
Question 2 answer: Heart cells undergo terminal differentiation
Explanation: Different cell types (e.g., neurons, skeletal and heart myocytes, adipocytes, keratinocytes) undergo terminal differentiation, in which acquisition of specialized functions entails definitive withdrawal from the cell cycle.
Question 3 answer: DNA replicates in the nucleus
Explanation: DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication.
Question 4 answer: The ability to reverse terminal differentiation might affect gene expression in a complex organism
Question 5 answer Cytoplasm replicates during mitosis
Explanation: This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. ... The outcome of binary fission is two new cells that are identical to the original cell.
