Answer:

D

Explanation:

The German doctor Rudolf Virchow proposed that all cells result from the division of previously existing cells, and this idea became a key piece of modern cell theory.

This results from cytokinesis when he observes cells splitting into two.

Answer:

The correct answer is - D.C-N bond

Explanation:

A chemical bond is formed between the carboxyl group of an amino acid to the amino group of the other amino acid and release a water molecule. It is a dehydration synthesis reaction.

So, the peptide bond normally formed by the reaction between amino acid from C1 of one amino acid molecule and N2 of the other amino acid molecule.

So the peptide bond that formed by this reaction is involve bonding of C-N bond.

Answer:

release of one G3P to make sugars and regeneration of RuBP

Explanation:

The Calvin cycle can be defined as a part of photosynthesis that utilizes the energy stored by light-dependent reactions to produce three-carbon sugars. The first carbohydrate produced by the Calvin cycle is a three-carbon sugar phosphate called glyceraldehyde-3-phosphate (G3P). Subsequently, G3P is used to produce other sugar molecules such as, for example, glucose. The Calvin cycle consists of three steps: 1-carboxylation (by using CO2 in a reaction catalyzed by Rubisco enzyme), 2-reduction of phosphoglycerate (ATP phosphorylation), and 3-regeneration of ribulose-bis-phosphate (RuBP) by using triose phosphates produced in the first two steps.

Answer:

Since variations in air pressure drive the winds on Earth, isobars also give meteorologists an easy way to assess wind direction and speed. Closely spaced isobars indicate large pressure changes over a small area, causing wind speeds to increase.

Answer:

mega-

kilo-

giga-

Explanation:

The standard unit of distance is in meters. Distance is the length of path covered by a body.

Only mega, kilo  and giga are units that are larger than the base unit of distance which is meters.

 Mega is of the order 10⁶

 Kilo is of  the order 10³

 giga- is of the order 10⁹

The prefixes below are submultiples:

centi-    10⁻²

micro-   10⁻⁶

Answer:

Cells must divide to perform functions such as growth of the organism, replacement of damaged or old cells, and asexual reproduction in some organisms.

Explanation:

Answer:

To divide, a cell must complete several important tasks: it must grow, copy its genetic material (DNA), and physically split into two daughter cells.

Explanation:

Cells perform these tasks in an organized, predictable series of steps that make up the cell cycle.

Answer:

Experimental Vaccine Herpes Vaccine = D

Attenuated = B

Purified macromolecule Vaccine = B

Recombinant-Vector Vaccine  = A

Inactivated or Killed = C

Diphtheria Vaccine = A

Explanation:

A Vaccine is an organic arrangement that gives dynamic obtained invulnerability to a specific irresistible infection. A Vaccine ordinarily contains a specialist that takes after a sickness causing microorganism and is frequently produced using debilitated or executed types of the organism, its poisons, or one of its surface proteins. The specialist invigorates the body's safe framework to perceive the specialist as a danger, pulverize it, and to additionally perceive and decimate any of the microorganisms related with that specialist that it might experience later on.

Vaccines can be prophylactic (to forestall or enhance the impacts of a future contamination by a characteristic or "wild" microorganism), or therapeutic (to battle a sickness that has just happened, for example, cancer).

The administration of Vaccine is called vaccination. vaccination is the best strategy for forestalling irresistible sicknesses

Answer:

A. Chloroplast

Explanation:

Chloroplast, often known as the kitchen of the cell, is where photosynthetic reactions combining light energy from the Sun into chemical energy [Glucose] that is stored as food. They contain a Green Color Pigment called 'Chlorophyll' that initiates the process, but Chlorophyll isn't an organelle, in fact, it is one of the elements of Chloroplasts. Similarly, Thylakoids are membrane-bound elements inside Chloroplast that aid in photosynthesis. While Mitochondria, [Power Houses Of Cells] generate energy for various processes in cells through ATP-Generations.
