A. Nerve signals from the brain are controlling the arm.
Explanation:
Bec ause it starts at the brain and to the arm/hand!.
Explanation:
In the given question,
suppose allele A and a determines the color of the fruit whereas allele B and b determines the shape of the fruit.
The genotype for white, disc shape fruits is- AABB
the genotype for yellow, long fruits is- aabb
F1 progeny will be- AABB x aabb
AaBb
F2 cross- AaBb x AaBb
AB Ab aB ab
AB <em>AABB AABb AaBB AaBb</em>
Ab <em>AABb AAbb AaBb Aabb</em>
aB <em> AaBB AaBb aaBB aaBb</em>
ab <em>AaBb Aabb aaBb aabb</em>
The genotype of F2 cross are-
1. 9/16 A- B- disc-shaped (like F1)
2. 3/16 A- bb spherical
3. 3/16 aa B- spherical
4. 1/16 aa bb long.
The decay product is Radon-222 gas
The physical change is when water slowly disappears when the sun shines upon it. Its weight and volume decreases.
The chemical changes is when the plants absorb the energy from the sunlight and convert water and carbon dioxide into sugar and oxygen gas. Physically, nothing has changed. The plant still looks the same. However, changes occur internally; these internal changes are chemical in nature.
The Coriolis effect<span> is caused by a combination of the inertia of moving air and the rotation of the Earth. Air tends to move from high pressure to low pressure in a straight line, but the rotation of the Earth means that, to an observer at one spot on its surface, the moving air appears to turn.
