Answer:
Dominant
Explanation:
Let the allele for short tail trait be represented by "T" and allele for long tail trait be represented by "t"
When a short tailed mutant with genotype "tt" is mated with long tailed mouse, following offspring will be produced -
Tt * tt
Tt, Tt, tt, tt
so the ratio of short tailed and long tailed mouse is 1:1
Here it is given as 4:3 . Hence, there are chances that short tail trait is dominant
In the second generation , two short tailed mouse are crossed. The following offspring will be produced
Tt * Tt
TT, Tt, Tt, tt
The ration of short tailed and long tailed mouse is 3:1
Here it is given as 6:3 i.e 2:1 . Hence, short tail trait is dominant over long tail trait.
When you are exposed to bright light, cells in the retina detect the stimulus and send it to the brain for processing. The brain commands the iris to constrict and decrease pupil size.
The structure that serves as a receptor in this system is Retina
<h3>How can we see the object?</h3>
Organisms adapted and evolved the eyes to see the surrounding environment. This ability to see begins when the visible wavelength of light enters the eye through a transparent covering called Cornea. The light enters the cornea and enters the inner of the eye through a round hole known as the pupil.
The light rays then enter the convex-shaped lens in the eye which focuses the beam of light on the back of the eye in the region of the tissue called the retina. The retina contains the photoreceptor cells-rods and cones in which the cone cells have the ability to detect three wavelengths of light especially blue, green and red which help us see various versions of the colour.
These cells convert light energy to chemical energy in the form of the action potential which gets transmitted to the part of the brain associated with the vision. This completes the pathway of the vision.
Thus, Retina is the answer.

Gregor Mendel was a scientist born in the Austrian Empire in 1822. He
conducted pea plant experiments and established many of the rules of
heredity. He was explaining the significance of invisible factors ( now
called genes ) for the inheritance. He also experimented with hawkweed
and honeybees. Mendel is referred to as "The Father of Genetics".
Answer: Genetics.
Answer:
How does biology change the way we think about life? - If plants didn’t produce their own food, you wouldn’t have anything to eat. So the next time you sit down to eat, you can thank the process of photosynthesis for your food.
Why is agriculture equally important to the other sciences? - Early farmers improved their crop production by inventing the first gardening tools. Today, farmers improve crop production through the use of Global Positioning Systems aka GPS. Agriculture is just as important, we need all of the new and old sciences.
Explanation:
Internal fertilization is when male deposits sperms directly in females body whereas internal fertilization is when male and female gametes unite outside the female body .
