Answer:
Meiosis and Genetic Variation.
Explanation:
When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between non-sister chromatids of homologous chromosomes. It results in new combinations of genes on each chromosome.
When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment. It results in gametes that have unique combinations of chromosomes.
In sexual reproduction, two gametes unite to produce an offspring. But which two of the millions of possible gametes will it be? This is likely to be a matter of chance. It is obviously another source of genetic variation in offspring. This is known as random fertilization.
Answer:
The correct answer will be-
1. Solar energy
2. Chemical energy
Explanation:
Photosynthesis is a complex process which takes place in green plants and algae. The process produces glucose molecule which is used by the plants to synthesise the energy molecules in the form of ATP and in the synthesis of other molecules.
The photosynthesis metabolic reactions synthesise glucose molecules using the carbon dioxide and water taking place in the presence of sunlight. Thus, the reaction converts the solar energy from the sun to the chemical energy stored in the bonds of glucose.
Thus, Solar energy and Chemical energy are the correct answers.
Answer:
Oxygen and glucose represent the reactants, while carbon dioxide, water, and energy represent the products. Reactants are the molecules that combine to start the reaction. Products are those molecules produced during cellular respiration.
Explanation:
Cardiac Output. Cardiac Output (CO) is the amount of blood pumped by the heart per unit of time and it depends on 2 important variables like below, Stroke Volume (SV) = the amount of blood ejected per beat of the heart (Normally, 70 ml/beat). Heart rate (HR) = heart beats per minute (normally, 70 beats/min).
Answer:The mitochondria take place most of the steps of cellular respiration. Both oxygen and glucose are cellular respiratory reactants. Cellular breathing is primarily ATP; carbon dioxide and water are waste-products.
