Plant cell do not have contractile vacuoles. What happens when a plant is watered?

1 answer:

8 0

The Effects of Dry Soil. Low soil moisture is often the reason this happens but other factors play a role. When temperatures are high and it is warm or hot, the plant loses more water through transpiration causing the plant to wilt if the water needs are higher than what is available.

Hope this helps a little, if you plan on copying just put it in your own words first.

What are loops within orbits?

True [87]

Answer:

precession

Explanation:

The orbit isn’t the simple ellipse, rather it is one that moves a little, loop after loop. This motion is called precession, and you may have heard about it when astronomers talk about the precession of the orbit of Mercury

A strain of bacteria has a CRISPR-Cas system, but a mutation has destroyed the function of the Cas9 gene. How will the strain of

bogdanovich [222]

If mutation destroys the function of the Cas9 gene then the bacteria will not be able to target a specific bacteriophage for destruction upon infection for the second time.

Cas9 is a 160 kilodalton protein that plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids and is heavily utilized in genetic engineering applications.
Its main function is to cut DNA and thereby alter a cell's genome.
Although Cas9 is an endonuclease and is evolved as a mechanism of immunity against viruses, they are not considered restriction enzymes.

To learn more about the Cas9 gene,

Selection is usually strongest in the male of the species. D) because sperm are small and plentiful, while eggs are large and energy-rich.

Phenotype refers back to the observable traits of an organism as a multifactorial effect of genetic trends and environmental influences. The organism phenotype includes its morphological, biochemical, physiological, and behavioral residences.

A person's genotype is their specific collection of DNA. extra especially, this term is used to refer to the two alleles a person has inherited for a selected gene. Phenotype is the detectable expression of this genotype – a patient's clinical presentation.

The sum of an organism's observable traits is its phenotype. A key difference between phenotype and genotype is that, even as genotype is inherited from an organism's parents, the phenotype isn't.

Both intrasexual and intersexual selection usually cause changes in phenotypes for males and little changes in female phenotypes. Why is sexual selection usually strongest in the male of the species?

a. Males are naturally more aggressive

b. Males have a smaller genetic component than females due to fewer X chromosomes

c. Males do not pass on their mitochondria and therefore have more invested in each individual mating event

d. Because sperm are small and plentiful, while eggs are large and energy-rich.

Using ideal ATP production numbers, how many ATPs would an individual generate if he or she consumed only pyruvate and carried o

IrinaK [193]

Answer: The ATP(Adenosine Triphosphate) that will be generated if one pyruvate molecule is carried through cellular respiration is 36.

Explanation: Pyruvate is formed through glycolysis cycle which breaks down glucose. The pyruvate is used in aerobic cellular respiration via the TCA cycle yielding 2 ATPs and the electron transport system yielding 34 ATPs. That makes it up to a total of 36 ATPs.
