Each kernel of corn on a single ear can inherit a different set of alleles from those inherited by other kernels. this characteristic makes corn a useful example of which law or principle? principle of dominance law of independent assortment law of segregation law of genetics
Mendelian genetics includes some laws which are law of dominance, law of segregation and law of independent assortment. The law followed by the corn for inheritance is law of segregation.
What are law of inheritance?Law of inheritance was given by Gregor Mendel, who is known as father of genetics.
The experiment was done on pea plant. Based on this experiment Mendel stated three laws. These are:
Law of Dominance: according to this law only dominant traits will be inherited in the offspring.Law of Segregation: according to this law, two copies of each hereditary factor segregate which results in acquiring one factor from each parent by offspring.Law of Independent Assortment: according to this law, pair of trait segregates independent of another pair during formation of gametes.Each kernel of corn on a single ear can inherit a different set of alleles from those inherited by other kernels. This is law of segregation.
Thus, the correct option is C.

Who was the scientist that identified the elliptical shape of the orbits of the planets in our solar system?.
Answer:
Johannes Kepler
Explanation:
Knowing then that the orbits of the planets are elliptical, johannes Kepler formulated three laws of planetary motion, which accurately described the motion of comets as well.
Kepler's Laws of Planetary Motion
Kepler's three laws describe how planetary bodies orbit the Sun. They describe how
1) Planets move in elliptical orbits with the Sun as a focus
2) A planet covers the same area of space in the same amount of time no matter where it is in its orbit
3) A planet’s orbital period is proportional to the size of its orbit (its semi-major axis).

Which of the following is an example of abiotic factors affecting an ecosystem? I. quantity and quality of water II. amount of light available III. nitrogen fixing bacteria IV. quantity of mineral A. I and II only B. I, II, and III only C. I, II, and IV only D. I, II, III, and IV
Which of the following is an example of abiotic factors affecting an ecosystem?
ANSWERThe correct answer is letter C. I, II, and IV only.
III. Nitrogen-fixing bacteria is an example of a living being (biotic) , so it isn't an abiotic factor that affects the ecosystem. While quantity, quality of water, amount of light (sunlight), and quantity of mineral in the soil are all examples of abiotic factors (non-living elements) that make difference in the environment.

How do humans reduce their greenhouse gas emissions
Answer:
Humans can reduce their greenhouse gas emissions (typically carbon, methane, etc.) by switching to all-electric appliances (a good brand that services this is Energy Star), using clean, renewable resources such as wind, solar, hydro, and thermal energy, and switching from a gas-powered car to electric, a huge step to reducing greenhouse gas emissions.
Explanation:
Greenhouse gases are gases that get trapped in the atmosphere and tend to produce more heat on Earth, the way a greenhouse traps heat for the purpose of growing plants better. However, greenhouse gases are bad for our atmosphere, and doing the things listed above can help improve our atmosphere. Hope this helps :)

With both ends of the muscle fixed, which of the following occurs if the load attempted is equal to or greater than the force generated by a muscle?.
With both ends of the muscle fixed, the condition of isometric muscle contraction will occur if the load attempted is equal to or greater than the force generated by a muscle.
What do you mean by Muscles?
Muscles may be defined as body tissues consisting of long cells that contract when stimulated and produce motion. They provide the action of movements in organisms.
When both ends of the muscles get fixed, it results in the isometric muscles contraction where the contraction of muscles occurs without motion. These contractions are used to stabilize a joint.
Therefore, with both ends of the muscle fixed, the condition of isometric muscle contraction will occur if the load attempted is equal to or greater than the force generated by a muscle.

The length of a DNA double helix increases by 0. 34 nm for every pair of nucleotides. The total number of nucleotides in a human body cell is 1. 2 X 10^10. Calculate the total length of double helix in a human body cell. Give your answer in metres.
The human body has 3.2 billion nucleotide pairs so the total length of the double helix in a human body cell is about 2 meters.
Two meters of DNA?DNA from a human cell is almost two meters long. To facilitate the organization of DNA within the cell nucleus, it is divided into elements called chromosomes.
With this information, we can conclude that the human body has 3.2 billion nucleotide pairs, so the total length of the double helix in a human body cell is about 2 meters.
