How does biodiversity depend on a species ability to reproduce

1 answer:

4 0

Biodiversity refers to the number of animal and plant species in a particular community per time. It is ideal for a community to have high degree of biodiversity.
The principal aim of reproduction is to prevent a specie from becoming extinct. The species in the community can only sustain biodiversity by giving birth to young ones who will continue to exist after they are dead. Thus, a specie ability to reproduce is what sustain the biodiversity.

poizon [28]

Explanation:

This starts with substrate level phosphorylation(glycolysis) in the cytosol of cytoplasms.Two ATPs are needed for phosphorylation of glucose.With eventual formation of 4 ATPs with 2NET GAIN ATPs,NADH+,and Pyruvate.

The Pyruvate reacts with co-enzyme A to form Acetyl coA-This is the bridge reaction or link reaction.

The Acetyl Co-A diffuses into the mitochondria where it combines with oxaloacetate to form citrate,the latter form Alpha ketoglutaric succinic,fumate,malate and back to oxaloacetate.The cycle of events is called the Kreb's Cycle.

Net of 2ATPs are formed,co-enzymes NADH+ and FADH2 ,water molecules,and Co2 are produced.These takes place in the mitochondria.

Then the NADH+ and FADH2 takes the hydrogen ions into the inner mitochondria where Hydrogen is split into electron and Protons.This forms the beginning of oxidative phosphorylation.

The electrons are transmitted by the carrier proteins to form the electron transport chains,which provide the PMF. The latter pumps the protons across the walls of mitochondria into the intramembrane space.

The high concentration of the protons produce the elecrochemical gradients which make the protons to diffuse back into the matrix. it is the changes in the elctrochemical gradients that supply the energy needed by ATPase enzymes for synthesis of ATPs. A total of 28ATPs are produced in oxidative phosphorylation.

Answer:

The total ATPs produced in the sequence of glycolysis pyruvatre,Co-enzyme A, kreb's Cycle and oxidative phosphorylation are 32ATPs per molecule of glucose splits in Glycolysis.

A proton has a speed of 3.0 × 106 m/s in a direction perpendicular to a uniform magnetic field, and the proton moves in a circle

jeyben [28]

Answer:

The magnitude of the magnetic field is 0.156 T.

Explanation:

Given that,

Speed of a proton, $v=3\times 10^6\ m/s$

Radius of the circular path, r = 0.2 m

When the proton enters in the circular path, the centripetal force is balanced by the magnetic force such that :

$\dfrac{mv^2}{r}=qvB\sin\theta$

q is the charge on proton

Here, $\theta=90^{\circ}$

$\dfrac{mv^2}{r}=qvB\\\\B=\dfrac{mv}{qr}\\\\B=\dfrac{1.67\times 10^{-27}\times 3\times 10^6}{1.6\times 10^{-19}\times 0.2}\\\\B=0.156\ T$

So, the magnitude of the magnetic field is 0.156 T. Hence, this is the required solution.

What is vitreous humor? Why do forensic scientists use it?

Bas_tet [7]

Answer and Explanation:

What is vitreous humor?

The vitreous humor is a clear, gelatin-like fluid within the eye that aids in giving it its rounded shape. It is comprised of several substances, including up to 98% water, sugars, salts, collagen and protein.

Why do forensic scientists use it?

In forensics, the is used to accurately determine a body's time of death. The fluids within the vitreous humor take longer to undergo the decay or putrefaction process. Thus, toxicology may accurately determine this based on the rising potassium levels within the vitreous humor- the levels rise in a steady, predictable pattern for certain time intervals. The potassium levels are usually used in the determination of the time of death or post-mortem interval of a corpse
