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.

At a crime scene you find a piece of glass with a red, dried liquid, and a yellow fiber on the edge lying on the ground. Upon closer inspection, you notice
that there is also a smudged fingerprint crossing the center of the glass. Your job is to plan and carry out an investigation to analyze this evidence. Explain
how you would collect,
preserve and analyze this evidence. What would you hope to find out from this piece of evidence? Indicate whether the glass, red liquid, fingerprint and yellow fiber are each individual or class evidence. Why?
Answer:
For smaller glass fragments should be placed in a paper packet and then in an envelope. Larger pieces should be wrapped securely in paper or cardboard and then placed in a padded cardboard box to prevent further breakage. For analyzing the glass I would start by comparing the refractive index of the sample to that of the possible source. Examination of samples under a regular microscope or a scanning electron microscope can give detailed information about the sample's physical and chemical characteristics. Since the liquid is already dried all you'd have to do is make sure to package it in paper which works since the glass can go in that. For the fiber I would remove it from the glass and collect it with some trace tape. Then the easiest method to get the fingerprint is called dusting, in which I would use a very fine powder that can stick to the oil in the fingerprint. Once the fingerprint becomes visible, lift it from the surface with clear tape and transfer it to another surface to then take into the laboratory to analyze further.
Glass, the liquid and the fiber would be class evidence while the fingerprint is individual.

What is the measurement of gravity
Answer:
Gravity is measured by the acceleration that it gives to freely falling objects. At Earth's surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second.

How can two organisms with a dominant trait for a specific feature produce an organism with a recessive trait for the same feature?
Answer:
because one of the organisms is heterozygous.
Explanation:
When an organism is heterozygous it carries both a dominant and a recessive allele therefore two organisms that are dominant for a specific trait can produce an organism with a recessive trait because one of those two organisms is heterozygous.

Drag each tile to the correct location. classify the energy sources as renewable or nonrenewable. energy obtained from water springs inside the earth energy obtained from natural gas energy obtained from coal energy obtained from burning plant waste
Renewable energy sources are the sources which can never be exhausted. This can include natural gas and water from spring in earth. non-renewable are the one which are exhaustible, which include coal energy
What are the types of energy resource?Renewable sources of energy involves sunlight, water, biomass, etc. This can be replenished naturally.
Nonrenewable sources includes energy from fossils, coal, petroleum, etc. These are the resources if once exhausted can never be replenished or will take millions of years to replenish.
Thus, on this basis one can say that water spring inside the earth, energy from natural gas are renewable sources of energy while energy from coal energy from burning plants is non-renewable energy resource.

A delta is a formation built up by?
A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment.
Answer:
Delta is build up by continuous deposition of sediments, which makes the water shallow, causing the landform to rise above the sea level. A delta is divided into four parts, i.e. subaqueous, subaerial, lower delta plain, upper delta plain.

A plant can have either brown (B) or red (b) leaves. Brown is the dominant
trait. If a plant has genotype bb, which best describes the plant?
Answer:
The plant would be red.
Explanation:
It would be red because red leaves are a recessive trait which has lowercase b's so if the genotype for the plant is bb, it would be red. If the plant had BB, it would be brown and if it had Bb it would be brown but, it would be a carrier of the red gene.

describe how glucose formed in a leaf becomes starch stored in a potato tuber
↪Glucose is usually converted into starch for storage. Starch is better for storage than glucose because it is insoluble. Plants like potatoes and other tubers, and also fruits like the banana store starch for later use. This starch is stored by special organelles, or cell subunits called amyloplasts.
☆...hope this helps...☆
Answer:
dehydration synthesis
Explanation:
monomers of the sugar glucose combine to form a single molecule of the sugar maltose. One of the glucose molecules loses an H, the other loses an OH group, and a water molecule is released when the water molecule is lost its no longer soluble hence its stored in the tuber as starch
