An action and its reaction are equal in
11111nata11111 [884]

Answer:

These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

Look at the equation for cellular respiration and write in which stage of the process each molecule is either used or produced.
Inga [223]

Answer:

Glucose -Glycolysis

6O2 -  pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation

CO2 - kerbs cycle  

Water- electron transport chain.

ATP - glycolysis, pyruvate oxidation & kerb cycle

Explanation:

Glucose (C6H12O6) is used in Glycolysis

6O2 is used in pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation

CO2 is produced in kerbs cycle in which 2 CO2 molecules are produced every single molecule of acetyl CoA

Water is produced in electron transport chain.

ATP is produced in following stages

a. The 6 ATP or 2 NADH molecules from glycolysis  

b. The 6 ATP or 2NADH molecules from pyruvate oxidation  

c. The 18 ATP or 6 NADH molecules from Krebs’ cycle  

d. The 4 ATP or 2 FADH2 molecules from Krebs’ cycle

Why are covalent bonds form when an electron is completely lost or gained from an atom
Andrei [34K]

Answer:

Covalent bonds are the types of Bond which is formed by sharing of an electron between two atoms of same element or two different elements. The bond which is formed by the completely lost or gained of an atom is known as ionic bond.

Explanation:

The most common example of covalent bond is formed from carbon atom. The valence of carbon atom is 4. Therefore, it is very hard to gain or lose an electron from the carbon atom. Therefore, the carbon tends to share the electron instead of completely losing or gaining the electron.

Ionic bond is very common and it can be formed by many elements from the periodic table. Ionic bond is more stable and stronger when compared to the covalent bond in nature.

Part 1: explain the similarities and differences between mitosis and meiosis and give an example that occurs in the world around
KatRina [158]

PART 1:

There are two types of cell division in eukaryotic cells:

* mitosis, which ensures the birth of cells identical to the mother cell during asexual reproduction. It gives diplide cells (2n). It takes place in one division.  It can be done by somatic cells.

* meiosis, a characteristic of male and female reproductive cells, which results in the production of sexual cells or gametes (haploid cell (n)) for reproduction. It takes place in two succesive divisions.

For points in common, both are preceded by the replication of DNA. They have the same divisional steps, and both involve eukaryotic cells.

PART 2:

The stages of division (for mitosis and meiosis) are:

Prophase: It is during this phase that the DNA condenses in the form of chromosomes.

Metaphase: It is then that the collection of condensed chromosomes at the equator of the cell occurs to form the equatorial plate.

Anaphase: During this very fast phase, the sister chromatids separate and migrate to the opposite poles of the cell.

Telophase: This is the last phase of mitosis, the chromatids are now at the two opposite poles of the cell and it begins to split in two.

For meiosis there is a second division, so we speak of prophase II, metaphase II, anaphase II and telophase II.
