The fluid which has very high osmolarity used in the experiment was Sucrose solution.

This fluid is important because it regulates the natural reaction of the leaves and also prevents interference from outside sources.

It was essential to keep it cool because cold temperature helps inhibit the rate of photosynthesis so it gives protection to degradation of proteins.

Check Your Understanding<br> Question: What is an adaptation?
AleksandrR [38]

Answer:

an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment

Explanation:

An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.

Describe the rock cycle. Discuss what can happen to rock material within the
Gnom [1K]

Answer:

The rock cycle is a constant transformation of rocks between the three rock types of igneous, sedimentary, and metamorphic. If the sediments are buried behind other layers of sediment, they can lithify and form sedimentary rock. When rocks melt, magma is formed. Rocks form deep below the Earth, move and sometimes change, rise to the surface, and eventually return to their original location.

A person with a phenotype of HbSS has sickle cell disease. A person with a phenotype of HbAS allele carries the sickle cell trai
makkiz [27]

The right answer is 1/4.

Two carriers of the disease each have a chance in two to transmit their sick gene ie: 1/2 * 1/2 = 1/4

A genetic disease is said to be autosomal recessive when

The gene involved is carried by an autosome (non-sex chromosome, X or Y in XY system of sexual determination);

The associated phenotype of this trait is recessive (the presence of two identical alleles is essential for the character to be expressed).

One of the two alleles is transmitted by the male gamete, the other by the female gamete.

But being a carrier of the mutation does not necessarily mean being sick, the manifestations of a genetic disease depend on its penetrance and the variability of its expression.
