Atoms in a molecule are joined together by a special link called a:

What percentage of rain falls in the dry desert?A.less than 8%B.less than 9%C.less than 10%D.less than 5%

Nuetrik [128]

I think the correct answer is C. Less than 10% of rain falls in a dry desert. Desert biomes are known to be the driest of all types of biomes. It receives very or almost no rainfall. Precipitation in a dry desert is about 250 mm per year.

I’m not sure how to answer this. I’ll give 15 points

ExtremeBDS [4]

Answer:

As the distance from the core increases, the temperature increases. You just have to know the layers of the Sun to answer this question/ The corona is on the very outside and the outer chromosphere is tucked inside of that. THe photosphere is tucked inside of the chromosphere.

Which of the following is an example of primary succession?

kiruha [24]

Answer:

B. the appearance of lichens and mosses in an area where a glacier has recently melted away

Explanation:

Ecological succession, which refers to the series of changes that occurs over time in an ecosystem, can be of two types namely: primary succession and secondary succession.

Primary succession is a succession that involves an area where no form of life has grown previously, hence, the area of land is barren e.g bare rock. Primary succession is first colonized by species called PIONEER SPECIES e.g. lichens, mosses etc.

According to this question, "the appearance of lichens and mosses (pioneer species) in an area where a glacier has recently melted away" is an example of PRIMARY SUCCESSION.

Using the table below, what is the total net gain of ATP molecules per glucose molecules?

svlad2 [7]

Explanation:

D. 38 ATP

During respiration, the breakdown of glucose undergoes several steps in order to produce ATP, namely in glycolysis, the Kreb's cycle and oxidative phosphorylation.

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.
