The pronunciation of the anatomic structure that conducts impulses to and from the brain and initiates reflex action to sensory information is the spinal cord.
- The spinal cord is a lengthy band of tissue that resembles a tube. It ties your brain and lowers it back together.
- Your spinal cord relays nerve messages back and forth from your brain to your body. You can experience feelings and move your body thanks to these nerve transmissions.
- The protection of the spinal cord, nerve roots, and many internal organs are the spine's three primary tasks. To keep your body upright, give it balance and structural support.
- Enable fluid movement. The spinal cord is surrounded by cerebrospinal fluid (CSF), which is additionally protected by three layers known as the meninges (dura, arachnoid, and pia mater). The spinal column, which consists of 33 bones known as vertebrae, houses the spinal cord.

Answer:
C. point the way north in early compasses
Explanation:
Answer:
Both parents are heterozygous i.e. Aa
Explanation:
This question involves a single gene coding for melanin pigmentation in humans. The dominant trait is normal pigmentation while the recessive trait is albinism. Note that, recessive trait means that both alleles must contain the same recessive alleles.
Let's say that the allele for normal pigmentation (presence of melanin) is A while the allele for albinism (without melanin) is a. The allele for normal pigmentation (A) is dominant over the allele for albinism (a). This means that allele "A" will always mask the phenotypic expression of allele "a" in a heterozygous state.
If a man and a woman with normal pigmentation gives birth to an albino child, it means the parents have the albino allele being masked in their genotype. In other words, both parents are heterozygous i.e Aa. If the two parents come together (see punnet square), gametes A and a will be produced by each parent.
The recessive alleles (a) of each parent's gamete combines to form a child that possesses the recessive trait (aa). Hence, the genotype of the parents will be HETEROZYGOUS (Aa).
Answer:
forest ecosystem is whereby the organism live together and interact with each other and their environment. The biodiversity in this ecosystem is reducing due to the following factors:
1. deforestation: if most of the trees in the forest are been cut down without replacement it will affect the animal living there. especially herbivores, they feed on this plant and use it as a hideout.
2. bush burning: if the bush is burnt it may lead the animals to ran away for there safety and some may die of hunger, and some trees and plants may also become weak and die therefore reducing food for other animals.
3. Climate change: Climate change is one of the reasons. As deforestation may lead to climate change and many other factors, Without transpiration and evaporation cloud won't be form and there will be no rain which may lead to draught and finally animal will die and others will migrate.
possible solution to this
1. Avoid deforestation, and bush and plant more trees.
2. the government can also make laws concerning deforestation, bush burning, burning of fosil fuels and tires to avoid climate change.
