According to the endosymbiosis theory, a mitochondrion shouldhave two membanes. Endosymbiotic theory is a theory that explains how eukaryotic cells may have evolved from prokaryotic cells. The theory deals with the origins of mitochondria and chloroplast, two eukaryotic organelles that have bacteria characteristics. These organelles are believed to have developed from symbiotic bacteria. According to this theory the mitochondria has two membranes; the outer membrane and the innermembrane.

The endosymbiotic theory is described that the the primitive eukaryotic cell has ingested a prokaryote to become the mitochondria and the chloroplast. The mitochondria is actually a primitive prokaryote capable of performing cellular respiration. According to this theory, the mitochondria (coming from a primitive prokaryote) must have two membranes, an inner membrane and an outer membrane.

Chloroplasts also have two cell membranes.

What happens to sister chromatids in meosis 2?

weeeeeb [17]

Meiosis II is very similar to Mitosis. In both cases chromosomes line up and sister chromatids are separated by the action of the spindle fibers. The daughter cells are genetically identical to one another.

Answer

The three metabolic pathways that make up aerobic respiration are really all parts of one larger pathway because the products of early pathways (like NADH) become utilize in the last one.

Explanation

Aerobic respiration is that type of respiration in which glucose molecule is broken down into CO2 and H2O in the presence of oxygen and 36 or 38 ATP molecules are produced.

Aerobic respiration complete in four main steps:

1. Glycolysis

In this step glucose is broken down into 2 molecules of pyruvate acid along with the production of 2 ATP molecules and 2NADH.

2. Oxidation of pyruvate

In this step pyruvate are oxidized in the presence of co-enzyme A to become Acetyl Co-enzyme A. Again 2NADH are formed in this step.

3. Kreb Cycle

It occus in mitochondria. Here acetyle coenzyme A enter Carbon fixation, reduction and regeneration phase. In this cycle 6 NADH, 2FADH2 and 2ATP are formed.

4. Electron transport chain

All NADH that are produced in above steps get oxidize and help in the production of ATP along with the release of electron and proton that help in the formation of water.

What is a truebreeding plannt

ANTONII [103]

I don't know much about it but i think it is when When you crosses 2 plants of the same pure lines parentage, the resulting F1 is termed as true-breeding plants.
True-breeding plants can also be produced by selfing (or self crossing) flowers form a pure line plant. When seeds from this fertilization are planted, they will give rise to homologous-homogeneous population.

Answer:

The Excretory System, The Reproductive System and The Endocrine System.

Explanation:

The Excretory System includes your bladder, uterus, and some of your organs. It is also called the "Urinary System". The Reproductive System includes your birth canal. This system helps to reproduce the body to have babies. The Endocrine System includes your hormones. It helps the body to depend on growth development or mood.

I hope this answers your question! :)
