A researcher illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae t

o different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He found that the largest groups were found in the areas illuminated by the red and blue light. What can you conclude about the bacteria that congregated in areas other than red and blue light?
Some bacteria have different forms of chlorophyll, which allows them to absorb different wavelengths of light.

Excess carbon dioxide in these areas attracted bacteria that complete anaerobic respiration.

Bacteria congregated in these areas because they contained carbon dioxide released by the algae.

Light of different wavelengths can be absorbed by aerobic bacteria but not by anaerobic bacteria.

A respiratory rate of less than ________ and greater than ________ in cases of trauma are criteria for immediate transportation
vovikov84 [41]

The question is incomplete as it does not have the options which are:

A. 8; 32

B. 10; 29

C. 12; 20

D. 5; 45

Answer:

The correct answer will be option-B

Explanation:

Trauma is the experience caused by the life-threatening events or events which help develop the psychological distress conditions.

The trauma can cause changes in the physiologic and psychological responses in humans. The CDC guidelines have stated criterion for immediate transportation of the person to the trauma centre in which one of the criteria is that if a person has the respiratory rate of less than 10 and greater than 29 will be transported to the trauma centre immediately.

Thus, Option-B is the correct answer.

Is selection more effective against recessive alleles in haploid or diploid organisms?
svet-max [94.6K]
The selection of more effective which is against recessive alleles in haploid organisms than diploid organisms. This is because haploid organisms contain a single set of alleles if a deleterious allele is present in haploid organisms which will produce its effect immediately as there will be no dominant allele which can prevent the expression of the recessive allele as it happens in diploids. Recessive allele will not produce its effect in presence of the dominant allele in the case of heterozygote which is Aa.
Where there is haploid the selection will be more effective when removing recessive alleles in the population. It is the homozygous recessive condition which as aa then the selection will act against recessive alleles.
