Answer:
The brain and the spinal cord are wrapped in three protective layers of tissue called the meninges. The cerebral spinal fluid goes between these layers to provide more cushion and protection. It nourishes and protects the nerve tissues of the brain and spinal cord. It also acts as a shock absorber, considering humans move a lot and fall.
Answer:
Since both plants are true breeding, it means that both are homozygous for the allele of the trait, that is flower color. The geranium plant with red flowers can be denoted as RR and the plant with white flowers can be denoted by WW. Since it is not mentioned in the question that which trait is dominant over the other, but one thing is sure that all the offspring will look alike in color, because their genotype will be same, RW.
The punnet square that best describes them is in attached figure, please see.
Hope it helps!
I think the answer is true
Those sediments can be formed from the weathering and erosion of preexisting rocks. Sedimentary rocks also include chemical precipitates, the solid materials left behind after a liquid evaporates. Metamorphic rocks form when the minerals in an existing rock are changed by heat or pressure below the surface.
The answer is a because if u do a punnett square to get your results like i did, each plant would end up with the phenotype Y(yellow)y(green), and since they all have 1 dominant and 1 recessive, the dominant trait takes over, but the recessive trait is still there but it doesnt show up.
hopefully my answer helps u
