a cross that results from a yellow and a purple allele together will result in what color corn kernel?

1.) yellow
2.) purple
3.) orange
4.) doesn’t exist

Answers

Answer:

1.) yellow

Explanation:

The high possibility of corn kernel colour is yellow if the yellow colour allele is dominant because the dominant trait or allele always appear in the offspring while on the other hand, the recessive allele does not appear in the shape and structure of the offspring so we can say that dominance is the reason for the appearance of colour in the seed or kernel.

Des a magnetic field flows though the inside of a magnet

Answers

Answer:

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

Explanation:

Answer:

However, the magnetic field lines do not just end at the tip of the magnet. They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole. Thus the magnetic field lines form a closed loop and do not have any ends.

List all six stages of the sensory pathway when an animal responds to information about its environment.

Answers

Explanation:

There basically four stages of sensory pathway when an animal responds to information about its environment.

and these stages of pathway are Reception,  transduction, transmission, and perception.

The sensory receptors are commonly described as specialised neurons found in sense organs that helps detect and respond to stimuli. The six stages of the sensory pathway which an animal responds to information about its environment are:

Reception: This falla under sensation. It is simply a type of sensory receptors detect that stimulus is present.Transduction: This also falls under sensation. It is a type of sensory receptors whose work is mainly to convert stimulus energy into electrochemical energy.Transmission: This falls under sensation. It is when neural impulses leave sensory organs and moves to the brain.selection: This falls under perception. It acts as detectors that filter the stimuli by responding to particular features of a stimulus while also ignoring the rest.Organisation: This falls under perception: It is known to organise the characteristics of sensory stimuli in a meaningful manner. Interpretation: This Fall also under perception. It is known to give meaning to sensory stimuli.

Sensation is simply regarded as a physiological process that uses sensory receptors in detecting and responding to stimuli.

Perception is referred to as the mental work of organising and interpreting sensory stimuli, making it meaningful.

how does shell color work to protect the egg from sunlight?

Answers

Answer:

Birds that live in cool climates lay darker eggs, as darker colors absorb more heat from the sunlight

Birds that live in hotter climates lay lighter eggs to prevent the egg from overheating.

The pigmentation acts to thermo-regulate the internal temperature of the egg, acting as a buffer between the embryo and the outside world. It does this by preventing overheating of the egg, through reflecting the sunlight off the pigmentation, rather than allowing it to be absorbed through the shell

In which stage of the cell cycle does the cell die
A) interphase
B) mitosis
C) apoptosis

Answers

The short answer is that cell death by apoptosis in various phases of cell cycle depends on the cell-type and inducer/stimulus. Hematopoietic cells can undergo apoptosis at all stages of cell cycle as noted by Bertrand. However, mesenchymal or epithelial cells usually undergo apoptosis at the G1/S or G2/M phase of the cell cycle.

Scientists believe that there are three jeans what contribute to skin color in humans.


Which of these best describes the inheritance pattern of skin color?

A. Multiple allele in which offspring recessive three allele from each parent.

B. Multiple allele in which offspring recessive three allele from only one parent.

C. Polygenic in which offspring recessive three allele from each parent.

D. Polygenic in which offspring recessive three allele from only one parent.

Answers

Answer:

C. Polygenic in which offspring receive three allele from each parent.

Explanation:

In genetics, a polygenic inheritance is an inheritance that involves more than one gene i.e. more than one gene controls a particular trait. This is the case of the skin color trait in humans, which is controlled by three genes.

However, since each gene contains two alleles, each parent will contribute three alleles for the three genes to the development of an offspring i.e. three alleles from the father and three from the mother will result in three genes in the offspring, each containing two alleles.

Food made by plants can get used by plants or by other animals as plants maybe eaten by other organisms that feed on plants by living on them, these organisms are called parasites. Or else the food can be used up by plants to carry out their metabolic activities ( activities at cellular level which keeps the plant alive ) like cellular respiration

Answer:

The food that is prepared by the plant is utilized for its metabolic processes, the excess food is stored in the form of starch, in the plants. ... The plants prepare starch by a process of photosynthesis with the sunlight along with "water and carbon dioxide

The food produced by the plants is in the form of sugar and the extra sugar produced is changed to starch and is stored in different parts of the plant such as in roots, stems, leaves, fruits and flowers.
