if the stomata could not close , would that be a good or bad thing for the plant?

Answers

Answer:

Transpiration is the process of evaporation of water from the leaves and stems to the atmosphere. The stomata close when the guard cells shrink, which in turn ceases the transpiration. Opening of stomata allows the process of transpiration, so the root cells do not die.

But if it can't close:

The downside to wide open stomata is increased water loss (transpiration). So stomata of cool-season turf grasses have decisions to make. The plant needs to capture and store energy via photosynthesis, however, excessive water loss through transpiration can result in plant injury or death.

It's a bad thing.

After that the food goes to the small intestine where absorption of nutrients and water also occurs.

Genetic
Infectious
Potentially lethal
Inherited

Answers

Answer:

Genetic = yes

Infectious = no

Potentially lethal = yes

Inherited = yes

Explanation:

"Sickle Cell Disease" is a blood disorder that is mostly inherited. An example of this is the "Sickle Cell Anemia," which means the body of the person is lacking in red blood cells. In order for an infant to carry such disease, both of his parents must pass the defective gene to him. It is a potentially lethal or deadly disease because if not given remedy, it may lead to several complications such as organ damage, leg ulcers, blindness, etc.

It is not infectious, which means that a person with a Sickle Cell Disease cannot transfer it to another person. It is not likely to spread as well.

Why are linked traits inconsistent with Mendel's laws?

Answers

Answer:

Linked Genes Violate the Law of Independent Assortment. Although all of Mendel's pea characteristics behaved according to the law of independent assortment, we now know that some allele combinations are not inherited independently of each other.

Explanation:

PLz, mark me as a brainlist :)

Mendel studied the transmission of genes in peas(pisum sativum) that were placed on different chromosomes. During meiosis there are two types of recombinations that make sure the offspring is different from the parent. First intrachromosomial recombination (crossing-over)where genetic material is exchanged between chromosomes. And interchromosomial recombination when homologous chromosomes are separated.

In Mendel's experiments only interchromosomial recombination was considered, but when Thomas Hunt Morgan experimented with Drosophilla Melanogaster he didn't get the same results because he focused on genes that were placed on the same chromosome. In this situation crossing over influenced the results.
