The statement that supports the modern extension of the cell theory that states "all living cells come from preexisting cells" is that they pass on their genetic information. Option B is the correct answer.
The presence of nucleus is like the central position in which all the machinery of the cell parts are all included.
All organisms only inherit genetic information just by specifying the structure and the function from parents. In that case , all the cells that arise from the type of the preexisting cells such that the genetic material needs to be replicated along with passing from the parent to the progeny cell in each of the cell division.
DNA, or the deoxyribonucleic acid in which it is hereditary material in the humans and all the other organisms. Nearly every cell in person's body is having same kind of DNA. A sperm and egg each of them just contain a set of the total pair of 23 chromosomes. When sperm fertilises egg, then the two copies of chromosomes are just present and an embryo just forms up.

Im 60% sure its B but if its not my bad
b. marine
c. estuaries
d. freshwater
Freshwater ecosystem is part of ponds, lakes, streams and rivers. i.e, option D is correct.
Ecosystem, the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space.
Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes, ponds, rivers, streams, springs, bogs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content.

A third phosphate group
A third ribose group
A second phosphate group
I'm thinking third phosphate group?
Electricity is added to recharge a battery. A third phosphate group is added to ADP to form ATP.
ATP or Adenosine triphosphate contains adenine, ribose and 3 phosphate groups.
ADP is converted to ATP by the following reaction:
ADP+Pi+energy⇄ATP
The analogy between battery and ATP can be explained as ATP is higher energy form and ADP is lower energy form like charged and uncharged form of the battery. When the terminal or third phosphate is removed from the ATP it becomes ADP and releases energy like a battery. The additional phosphate group when added to ADP forms the ATP molecule like the energy spent by the batteries are recharged by putting in additional energy. Here the additional energy is provided by the third phosphate group.
Answer:
The correct answer is B) A third phosphate group.
Explanation:
ATP is Adenosine Triphosphate and ADP is Adenosine Diphosphate.
ADP gets converted into ATP in presence of inorganic phosphate and energy, irrespective of whether the energy is obtained from sunlight or from certain exothermic reactions. ATP is converted into ADP, releasing energy and inorganic phosphate.

liquid
gas
plasma
Answer: Liquid
Explanation:
Liquid and gases are fluids as they can flow. Convection takes place when the the particles having more energy is replaced with the particles having less energy.
The hotter particles moves and takes place of the colder particles when a liquid is heated. The liquid that lies in the hotter region is less dense than the colder regions. So, less dense particles move to replace the more dense particles.
Hence, the correct answer is Option B
