Nervous tissue can be found mainly in the ____________ , spinal cord, and in the limbs as ____________ .

Pavlova-9 [17]

Answer:

1. Brain

2. Peripheral nerves

Explanation:

The nervous tissue or the nervous system is a system in the humans or animals formed by the neurons.

The nervous system can be categorised into two types based on the structure and functions: the peripheral nervous system and the central nervous system.

The central system of neurons comprises of the neurons present in the spinal cord and the brain and the peripheral system which comprises the nerves of the organs present except the brain and the spinal cord like the nerves in the limbs (legs, arms).

Thus, Brain and Peripheral nerves are correct.

A young couple went to see a genetic counselor because each had a sibling affected with cystic fibrosis. (Cystic fibrosis is a r

mel-nik [20]

Answer:

a) The correct answer is 1/2 or 0.5

Cystic fibrosis is a recessive disorder and her sibling has a disease but none of the parents had it. Thus, each of the parents must be the carrier of the disease, that is, both of them must be heterzygous.

So, if we cross Cc x Cc, it results in the genotype ratio of 1 (CC) : 2 (Cc) : 1 (cc)

Thus, 2 out of 4 would be the carrier of the disease.

b) 1/16

The probability of female to the carrier is 1/2

Same is the case with male partner due to the probability that he would be the carrier is 1/2

If both are carrier then, there is only 1/4 chances that the offspring will have the disease (as per cross shown above).

Now, the probability that the offspring will have the disease = product of all the above probabilities. (The probability of occurrence of two independent events is equal to the product of their individual probabilities).

So, $\frac{1}{2}x\frac{1}{2}x\frac{1}{4}$ = $\frac{1}{16}$

c) 1/8

The probability of female to be the carrier is 1/2

The probability male to be the carrier is 1/2

If both are carrier then, there is only 2/4 chances that the offspring will be the carrier of the disease (as per cross shown above).

Now, the probability that the offspring will be the carrier = product of all the above probabilities. (The probability of occurrence of two independent events is equal to the product of their individual probabilities).

$\frac{1}{2}x\frac{1}{2}x\frac{2}{4}$ = $\frac{1}{8}$

Pick one organism that lives in the savanna and explain why it has adapted to this environment. Do you think the adaptations of

Korolek [52]

Answer: Elephants

Explanation:

Elephants have being able to survive in the savannah due to its ability to adapt. Elephants natural have no sweet glands so they have to device other means to cool their selfs, th ey achieve this by flapping their ears to create the cooling effects they need to survive in their environment. They also posses tusk and long trunks which they used for eating and drinking. The adaptation of the elephants to the African savannah has being due to the effects of environment and the genes. A popular example is an African elephant is different from it’s counterpart from Asia. Africa elephants have bigger ears unlike Asians which are smaller
