Answer:

Yes,  in its atmosphere(21% oxygen) humans can walk on this planet without the aid of a space suit

Explanation:

The atmosphere of the earth has a percentage of 20.946% similar to the planet x with 21% oxygen.

Most living forms depend on the air: oxygen is necessary for the breathing of human beings. In the first 100Km the oxygen composition in the atmosphere remains stable.

Humans are very sensitive to oxygen levels, the magnitude of the oxygen deficit can lead to death but 215 is a  bearable percentage.

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.

SIZIF [17.4K]
<span>In this case, all these statements are true. Salinity is the salt in the water. Jacques Piccard and Lt. on Walsh were the first people to explore the deepest part of the worlds ocean known as the Mariana Trench in The Challenger Deep, and Jason 1 is a satellite released by NASA to monitor world ocean circulation and study the way the atmosphere and ocean interact with each other to improve the predictions for the climate when it comes to major weather events like El Nino.</span>

Which of these is not part of insect immunity? A. enzyme activation of pathogen-killing chemicals B. activation of natural kille
Firlakuza [10]

Insect immunity doesn't include the property of an enzyme activation of pathogen-killing chemicals.

What is enzyme activation of pathogen?

Due to various trehalose's importance in pathogenic organisms, there has lately been a surge of interest in trehalose metabolism for therapeutic applications.

  • TPP (trehalose-6-phosphate phosphatase) is an important enzyme in the most important biosynthetic pathway (OtsAB).
  • The enzyme properties of recombinant TPPs from five key nematode and bacterial pathogens, including three new members of this protein family, are compared here.
  • The kinetics of trehalose-6-phosphate hydrolysis demonstrate that all five enzymes exhibit burst-like kinetic behaviour, defined by a drop in enzymatic rate beyond the pre-steady state.
  • Multiple global conformational changes in members of this enzyme family during substrate processing can explain the observed super-stoichiometric burst amplitudes.

Hence, the correct answer is option A
