Explanation:
The widely accepted theory which explains the formation of the solar system is known as the Nebular theory of origin.
The Nebular theory states that the solar system is formed by the explosion of the large gaseous clouds in the centre due to various factors which took place around 457 million years ago.
The explosion leads to the formation of the dust particles which accumulated in large amount in the centre and the suspended particles revolved around it and formed the planets and the centre is known as the sun.
The theory can be proved as :
1. the direction of rotation of planetary bodies are in the same around the same direction.
2. The suspended particles formed the disk around the planets.
3. The planets near the Sun are small and possess lass amount of metals and the silicates whereas the planets far away from the Sun-like Jupiter are larger due to the presence of these metals and silicate which attracted the hydrogen and Helium.
Answer is;
The animal population in the environment will increase.
This is because the grass is the main producer in a habitat. Its plentifulness directly influences that of the consumers up the food web. Increase in grass population means reduced competition for primary consumers and their population will therefore increase. This will also reduce competition for secondary consumers and tertiary consumers up the chain.
Answer:
B. there were more double crossovers in the progeny than would be expected based on probability
Explanation:
Crossing over or recombination can be defined as the exchange of genetic material between homologous chromosomes during meiosis. Moreover, the coefficient of coincidence is the number of double recombinants found in the progeny. The coefficient of coincidence can be estimated by the following equation:
Coefficient of coincidence (COC) = ADRF / EDRF
where ADRF = Actual Double Recombinant Frequency
and EDRF = Expected Double Recombinant Frequency
In the case above described, ADFR is higher than EDRF, and therefore COC will be higher than 1.
The amount of ATP produced by anaerobic versus aerobic metabolism depends on the availability of oxygen. Cellular respiration can be anaerobic or aerobic respiration, depending on whether or not oxygen is present. Anaerobic respiration makes a total of 2 ATP. Aerobic respiration is much more efficient and can produce up to 38 ATP with a single molecule of glucose.
This rock can be classified as:
an igneous rock.
Igneous rocks are made up of
randomly arranged interlocking crystals and the important minerals that can be
found in igneous rocks are feldspars, quartz, olivines, pyroxenes, amphiboles,
and mafic minerals. All of these minerals are important in the formation of
almost all igneous rocks, and they are basic to their classification.
