A plane is traveling at 80 m/s. To prepare for landing, it decreases its speed to 50 m/s in 120 s.
emmainna [20.7K]

Answer:

The deceleration of the plane is 0.25 m/s^{2}.

Explanation:

Deceleration is the converse of acceleration.

From first law of motion, we have;

v = u + at

where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.

Thus,

v = 50 m/s

u = 80 m/s

t = 120 s

50 = 80 + 120a

50 - 80 = 120a

-30 = 120a

a = \frac{-30}{120}

  = -0.25

a = -0.25 m/s^{2}

The deceleration of the plane is 0.25 m/s^{2}.

The LMand LNalleles at the MN blood-group locus exhibit codominance. Give the expected genotypes and phenotypes and their ratios
Dmitry [639]

Answer:

Please find the expected genotypes and phenotypes of the progenies of each cross below.

Explanation:

In the MN blood-group locus of the gene, alleles LM and LN exhibit codominance i.e one allele is not dominant or recessive to the other, hence, they are both expressed when they occur in a heterozygous state (MN).

Considering the following crosses (find the punnet square attached);

a)LMLM x LMLN - The progeny are LMLM and LMLN in the genotypic ratio 1:1. Phenotypic ratio is Blood type M (1) : blood type MN (1)

b) LNLN x LNLN - The progeny are all LNLN offsprings with a phenotypic and genotypic ratio 4:0. All offsprings will have a blood type N (4)

c) LMLN x LMLN - The progenies are LMLM, LMLN and LNLN in the genotypic ratio 1:2:1 respectively. The phenotypic ratio is Blood type M (1) : L

Blood type MN (2) : Blood type N (1)

d) LMLN x LNLN - The progeny are LMLN and LNLN with genotypic ratio 1:1 and phenotypic ratio blood type MN (1) : blood type N (1)

e) LMLM x LNLN - The progeny are all LMLN offsprings with penotypic ratio blood type MN (4)

Andreas93 [3]
<span>The factor which is the least influential in affecting the biodiversity of wetlands is A. type of wetland. Regardless of its type, there will still be a lot of flora and fauna in a certain wetland. Other factors such as food resources, nutrients, and whether there is enough water are far more important for the existence of biodiversity than the type of wetlands.</span>

The process of antibody-dependent cellular cytotoxicity (ADCC) allows ______ cells to bind to antibody-coated host cells that ma
EastWind [94]

Answer:

The right response is "Natural killer".

Explanation:

  • Natural killer cells constitute immune cells which could also identify and ultimately destroy distressed or damaged cells. This might also target cancerous as well as tumors.
  • That alone reduces inflammation that lyses this same cell cycle rather than being amongst the very first cells towards prepare an inflammatory system, and even more so towards virus cells, participating including its destruction.
