Answer:

A grasshopper

Explanation:

The options you were given are the following:

  • Coyote
  • Sea Turtle
  • Grasshopper
  • Nurse Shark

In biology, metamorphosis is a process in which an animal physically develops after birth or hatching, dramatically changing its appearance.

An example of an animal that goes through metamorphosis is a grasshopper. However, unlike the butterfly, which goes through the caterpillar (larva) stage, the grasshopper goes through incomplete metamorphosis. This type of metamorphosis consists of three stages: the egg, the nymph, and the adult.

You can see the life cycle of a grasshopper below:

Answer:The frog and the ladybug go through a metamorphosis. The ladybug larva looks like a completely different insect from its final adult form. The frog goes through a tadpole stage in which it lives underwater, and then develops into a frog that can live on land.

In peas, yellow seeds (Y) are dominant over green seeds (y). If a yy plant is crossed with a YY plant, what ratio of plants in t
LenKa [72]

The ratio of yellow seed phenotype with green seed color seed offsprings will be 4:0.

Explanation:

Given that:

Dominant trait is Y (yellow seed color)

recessive trait is y (green seeds color)

cross between YY and yy, According Mendelian Genetics dominant trait will be seen in phenotype as it masks the effect of recessive gene.

Punnet square shows that:

    Y      Y

y   Yy    Yy

y   Yy     Yy

All the plants produced will be tall phenotype.

The yellow seed plant plants will be heterozygous i.e Yy

the phenotype ratio is 4:0

The genotype ratio is 4:0

The genotype of the offspring is Yy

phenotype is yellow colored seed plant.

If the force exerted on a sled is 100 N and the mass of the sled is 50 kg, what is the acceleration of the sled?
Anna35 [415]
<h3><u>Answer;</u></h3>

acceleration= 2 m/s²

<h3><u>Explanation;</u></h3>

From the second Newton's Law of motion the resultant force is directly proportional to the rate of change in momentum.

That is;

F = ma

Thus; F = 100 N, m = 50 kg

a = F/m

  = 100/50

  = 2 m/s²

Damm [24]

Given: The systolic arterial blood pressure observed for 20 dogs is normally distributed with a mean of 152 mm of mercury (Hg) and a standard deviation of 18 mm of Hg.  

To find: P(100 < 152)

Method: Calculation of Z-Score followed by the probability or area of the bell curve at X = 100.

Solution:

Mean u = 152, std s = 18

Z score = \frac{X-u}{s} = \frac{100-152}{18} = -2.89

The value of P(100<152) is calculated by looking at the value of Z in the Z score for the standard normal distribution given in the image.

P(Z=-2.89) = 0.0019

The P(Z = -2.89) corresponds to the area in the left tail of the bell curve.

Thus the probability of 100 mm Hg blood pressure is 0.0019.

If a molecule of DNA has 30% Adenine how much of the other bases will be present?
anygoal [31]

Answer:

If a DNA molecule has 30% Adenine the percentage of the other bases is Thymine: 30% Cytosine: 20% Guanine: 20%.

Explanation:

When the percentage that a base has in a DNA molecule is given, the percentage of the other bases can be known using the Chargaff's base pair rule.

A DNA molecule has the information of the genome of a living being, according to a specific sequence of its nitrogenous bases adenine, guanine, cytosine and thymine.

Chargaff was able to establish that in a DNA molecule the ratio of purine : pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, taking into account the complementarity of bases.

Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:

  • <em>Adenine 30%. </em>
  • <em>Thymine 30%. </em>
  • <em>Cytosine 20%. </em>
  • <em>Guanine 20%. </em>
  • <em>Total ..... 100% </em>

In this case, the <u>Chargaff rule is useful to determine the percentage of nitrogenous bases that exist in a DNA molecule, knowing the percentage of a single base</u>.
