The African Region is the part of the world with both the highest birth and infant mortality rate. World Health Organization estimated these numbers back in 2015 where 75% of newly born children die only under the age of five. The most probable reason for this is poverty and the continuous struggling economy of Africa.
The movement of H+ across a membrane down its concentration gradient. oxygen picks up electrons from the oxidation of glucose at the end of the electron transport chain. Carbon dioxide results from the oxidation of glucose.
Answer:
e. regenerates a three-carbon molecule and alcoholic fermentation does not.
Explanation:
Lactic acid fermentation includes the reduction of pyruvate into lactate. Lactate is a three-carbon molecule. Reduction of pyruvate into lactate also regenerate NAD+ required to continue the process of glycolysis.
Alcoholic fermentation includes decarboxylation of pyruvate into acetaldehyde followed by its reduction of alcohol. The alcohol formed as end product is a two-carbon molecule (ethanol). Here, NADH serves as electron donor and is oxidized into NAD+. Therefore, both the process regenerate NAD+ but ethanol fermentation does not regenerate the three-carbon molecule since one carbon is lost as CO2.
Answer:
All green algae produce large, stationary eggs
Explanation:
The research on the evolution of land plants has shown that the plants have evolved from the green algae especially the "Charophytes" which grows in on the rocks attached to the rocks on the seashore.
The evidence that plants evolved from the green algae was supported by the:
1. The storage material of both the plants and algae is the same that is starch
2. both the algae and plants have the sporophytic and gametophytic life cycle
3. Both the plants and algae possess the same type of the photosynthetic pigments like chlorophyll a,b,c,d and others.
4. Both have a cell wall made of cellulose
But the green algae produce the stationary eggs does not support the hypothesis as the plants not necessary produce the stationary eggs.
Thus, the selected option is correct.
Answer:
The 5 trees that did not live couldn't receive nutrients as well as the others.
Explanation:
A hypothesis doesn't have to be a perfect statement, it is mainly a scientific guess that is further taken to the experimental level and research level. Your answer could consist of anything as long as it makes logical sense.
