Answer:

How do trees turn color?

In the fall, trees break down the green pigments and nutrients stored in their leaves. The nutrients are shuttled into the tree's roots for reuse in the spring. It's then that the trees take on their autumn hues. As leaves lose their chlorophyll, other pigments become visible to the human eye, according to Bryan A.

The sodium amytal test involves the injection of a small amount of sodium amytal into the carotid artery on one side of the neck

romanna [79]

The sodium amytal test involves the injection of a small amount of sodium amytal into the carotid artery on one side of the neck. This injection anesthetizes the hemisphere on that side for a few minutes.

A method that involves injecting a small amount of a barbiturate into the carotid artery on one side of the head to assess hemispheric functions, usually memory and language. The cerebral hemisphere that was injected selectively becomes impaired for 10 to 15 minutes during this operation.

Various cognitive tests are given while each hemisphere is seperately anaesthetized; deficiencies on these tasks imply that these functions are represented in the anaesthetized hemisphere. Prior to a temporal lobectomy, the Wada test may be utilised in cases with severe and uncontrollable epilepsy. Also known as the Wada technique, intracarotid sodium Amytal test (ISA), Wada dominance test, and intracarotid amobarbital procedure.

Identify the genotypes of the male and female flies used in cross 2.

ANTONII [103]

Answer:

Mother - XAXA

Father - XY

Explanation:

Please see the attached image - complete question

Solution -

In the second cross the female is affected while the male is unaffected

The disease mentioned in the question is dominant X inked which means even one X chromosome can cause the disease. Thus, it will impacts males more than females.

Let the allele representing a diseased X gene be XA

and the allele for normal X gene be X

The offspring have all diseased males, which means that the genotype of affected female will be XAXA

And the genotype of unaffected male will be XY
