production of body heat: The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulations. Hence, production of body heat is not a function of the skeletal system.
Answer:
The key difference between angiosperms and gymnosperms is how their seeds are developed. The seeds of angiosperms develop in the ovaries of flowers and are surrounded by a protective fruit. Gymnosperm seeds are usually formed in unisexual cones, known as strobili, and the plants lack fruits and flowers.
Explanation:
The heart has four valves - one for each chamber of the heart. The valves keep blood moving through the heart in the right direction. The mitral valve and tricuspid valve are located between the atria (upper heart chambers) and the ventricles (lower heart chambers)
The answer is 1/2.
If:
R - t<span>he dominant allele for red kernels
r - t</span><span>he recessive allele for yellow kernels
Then:
RR - dominant homozygote
Rr - heterozygote
rr - recessive homozygote
The cross Rr x rr will result in 1/2 of offspring with red kernels (Rr) and 1/2 of offspring with yellow kernels (rr):
Parental generation: Rr x rr
Offspring generation: Rr Rr rr rr
So, there are 2 out of 4 Rr offspring (2/4 = 1/2) and 2 out of 4 rr offspring (2/4 = 1/2).</span>
Answer:
Homologous structures have the same ancestry, but may no longer serve the same function. For example, the bones that make up human fingers were inherited from an ancestor that's shared by all mammals.
