Answer:
Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen
Explanation:
i did a bit of google and that popped up o:
Digestion <span>breaks carbohydrates down into basic subunits ("building blocks") called saccharides, or sugars. </span>
<em><u>Xylem</u></em> is a part of <em><u>Vascular bundle </u></em>which carry up <em><u>water</u></em> and <em><u>minerals</u></em> from roots of plant to its leaves.
So, the required answer is :
=》A. <em><u>Water and minerals</u></em>
<span>The question above is incomplete, the remaining part of the question is given below:
1. Since more offspring are produced
than an environment can support, organisms within a population must compete for
resources to survive.
2. Due to variations within the population, some competitors will be better
equipped for survival than others.
3. The best-equipped organisms will survive and will produce well-equipped
offspring.
4. Variations that help with survival will be passed on to future generations
and will rapidly change the whole population.
Which point is flawed as written above?
A. point 1
B. point 2
C. point 3
D. point 4</span>
ANSWER
The correct option is D.
All the options written above about Darwin's theory are quite correct with the exception of option D. Charles Darwin was the scientist who proposed the theory of evolution by mean of natural selection. Darwin submitted that, due to the scarcity of needed resources in an environment, it is only the fittest individuals in a particular population that will be able to survive and produce offspring that share their adaptability features. As this continue from generation to generation, it leads to evolution, which is defined as the changes overtime, which give rise to new species that share a common ancestors. Contrary to the point made in option D, evolution by natural selection is not a rapid process at all, it is a process that occur over a long period of time.
