Answer:
speed = 1200 m/s
Explanation:
given data
frequency = 60 Hz
wavelength = 20 m
solution
we get here speed of a wave that is express as
speed = Frequency × wavelength ...............................1
put here value and we get speed
speed = 60 × 20
speed = 1200
so speed of a wave is 1200 m/s

Some laboratory mice are spotted, due to a dominant gene. Solid color is recessive. A solid color female mouse is mated to a spotted male. Both parents are homozygous. What percentage of mice should be found in the litter?
Answer: percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.
Explanation: First, homozygous means each parent have matching chromosomes (Like XX, instead of Xx)
Lets make a punnet square and show the data. We will use 'S' for spotted and 's' for solid
The punnet square shows that the percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.
Hope this helps :)
The percentage of mice that will be spot-ted is 100%, and 0% chance of being solid colored.
Calculation of the percentage:In the first time, h-o-m-o-z-y-g-o-u-s means each & every parent should have matching chromosomes (Like X-X, instead of X-x)
So based on this, we can say that The percentage of mice that will be spot-ted is 100%, and 0% chance of being solid colored.
in this way, the percentage is determined.

Which of the following statements about plant reproduction is TRUE?
a. Plants only reproduce sexually.
b. Reproduction in plants usually requires windy environments.
c. Flower shape, color, and odor can attract animals needed for plant reproduction.
d. Reproduction in most plants requires honeybees to carry pollen from one plant to another.
Answer:
D
Explanation:
A is wrong since plants reproduce sexually and asexually.
B is not logical since plants do not need windy environments for reproduction.
C is not logical either since animals and plants do not reproduce.
D is the most logical answer since honey bees play an important role in pollinating plants and carrying pollen from one plant to another since plants can not move and are autotrophs.
Reproduction in most plants requires honeybees to carry pollen from one plant to another is true about plants reproduction.
What do you mean by plant reproduction?Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent.
The parent plants have male and female sex cells, called gametes. The genetic material from the male and female gametes combines to produce offspring. We call this process fertilization. The product of sexual reproduction are seeds.
Plant fertilization is the joining of male and female gametes, resulting in a zygote. The most generalized form of this process requires four steps: pollination, germination, penetration of the ovule, and fertilization.

Which of the following depicts correct base-pairing in DNA?
A-G-A
B-A-U
C-C-T
D-T-A
Answer:
D. T- A
Explanation:
In dsDNA the bases in the two strands are paired through hydrogen bonds forming base pairs (bp). Adenine forms two H-bonds with thymine from opposite strand and vice-versa. Similarly, guanine is bonded with cytosine with three H-bonds. As a result, always a purine comes opposite to a pyrimidine.

Which of the following is always true of two organisms in
the same taxonomic class?
A.They can breed with one another
B.They have certain physical features in common
C.they evolved at the same time
D.they live in the same ecosystem
Answer:
they can breed with one another, they have certain physical features in common, they evolved at the same rate, they live in the same ecosystem. Lions and house cats share common features, but cannot breed with one another.
Explanation:
They share a common ecology, they may breed with one another, share some physical characteristics, evolve at the same rate, and inhabit the same ecosystem, hence option D is correct.
What are the taxonomic classes?If two species are members of the same class, they are also members of the same higher-level taxon. They share the same phylum and kingdom in this instance.
Kingdom, phylum or division, class, order, family, genus, and species are the seven main taxonomic ranks.
The taxon with the greatest number of species is the kingdom. In taxonomy, it is the broadest category into which the creatures can be divided.
The classification of five kingdoms was made by R.H. Whittaker. The kingdoms of Monera, Protista, Fungi, Plantae, and Animalia are included in this classification.
Therefore, option D is correct.

Hitchhiker's thumb (H) is dominant to no hitchhiker's thumb (h). A woman who does not have hitchhiker's thumb marries a man who is heterozygous for hitchhiker's thumb. What is true of their offspring?
Answer:
There is a 50% chance the kids will have Hitchhiker's thumb
Explanation:
Because Hitchhiker's thumb is dominant and the woman doesn't have it it's safe to assume her genes for it are hh. In a punnet square it would look like
h h
H | Hh Hh
h | hh hh
If that makes any sense I hope it does
Point is, 2 of the 4 boxes would say Hh and the other two would have hh

Which best explains why earthquakes sometimes occur in the same locations as mid-ocean ridges and rift valleys
Answer:
The reason why earthquakes sometimes occur in the same locations as mid-ocean ridges and rift valleys securely is:
Active tectonic plate edges are found at these locations.Explanation:
Earthquakes are caused by the release of energy that occurs regularly at the edges of tectonic plates, which with their movement allow the release of said energy, which later translates into an earthquake. In simpler words, imagine that tectonic plates are pieces of a domino together next to each other trying not to leave space, each union between one piece and another is a possible focus of energy release if these pieces move, and if that happened, whatever was on them would feel an earthquake or tremor.
There are places that are much more prone to earthquakes than others, for example, San Andreas Fault, which is heard a lot by the great earthquake it could cause in California.
Answer:
Faults form because crust gets cracked when plates move apart along divergent plate boundaries.
Explanation:
Just took the quiz and got it right. Believe me on this.
