Answer:
[tex]F_{net}[/tex] is 26.25 N
Explanation:
Given that: [tex]F_{x}[/tex] = 20 N, [tex]F_{y}[/tex] = 17 N.
This implies that the two forces are acting at right angle to each other. Thus applying the Pythagoras theorem, we have;
[tex]F_{net}[/tex] = [tex]\sqrt{F_{x} ^{2} + F_{y} ^{2} }[/tex]
= [tex]\sqrt{(20)^{2} + (17)^{2} }[/tex]
= [tex]\sqrt{400 + 289}[/tex]
[tex]F_{net}[/tex] = [tex]\sqrt{689}[/tex]
= 26.2488
[tex]F_{net}[/tex] = 26.25 N
The net force is 26.25 N.

The events is a likely result of thermal water pollution is Rainbow trout disappear from a stream because of high water temperatures. Thus, option "D" is correct.
What is water pollution?Water pollution occurs when materials are disposed in water body, thus making it unfit for use. A polluted water can not be used for various purposes that water can be used for. Examples include: recreation, drinking, washing etc.
Water scarcity is the situation when available water is not sufficient for the use of organisms in a community. This majorly occurs in arid area.
Thus, option "D" is correct.

Answer:
True
Explanation:
Humidity refers to the moisture in the air or the amount of water vapor found in the air, and it is very high in rainforests is True statement.
What is Humidity?The amount of water vapor in the air is known as humidity. The humidity will be high if there is a lot of water vapor in the atmosphere. It feels wetter outside as the humidity rises.
Relative humidity is the term typically used to describe humidity in weather reports.
The amount of water vapor that is actually present in the air, represented as a percentage of the maximum amount of water vapor that the air can contain at the same temperature, is known as relative humidity.
Therefore, Humidity refers to the moisture in the air or the amount of water vapor found in the air, and it is very high in rainforests is True statement.

best answer.
A. The amount of DNA determines what an organism looks like
B. The sequence of the DNA determines which proteins can be produced
C. The number of cells that have DNA determines how an organism looks
D. The location of DNA in a cell determines which proteins are made
Answer:
Explanation:
B. The sequence of the DNA determines which protiens can be produced
DNA carries the genetic information for making proteins. ... The base sequence determines amino acid sequence in protein. Messenger RNA (mRNA) is a molecule which carries a copy of the code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.

Answer:
Individuals that are well adapted to their environment will survive and reproduce
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

A virus killed most of the seals in the North Sea (eg, dropped the population from 8,000 to 800). In an effort to help
preserve the species, scientists caught 20 seals and used them to start a new population in the northwest Pacific Ocean.
Which of the following factors would most likely have the LEAST impact on this new population?
genetic drift
bottleneck effect
founder effect
random mating
Answer:
random mating
Explanation:
The founder effect is most likely to have the least impact on this new population. Therefore, option C is correct.
What is the founder effect?When a small portion of the original population establishes a new colony, it has an effect known as the founder effect. Due to the colony's modest size, there may be less genetic variety from the original population. a non-random selection of the original population's genes.
While other disease alleles resembling those in the parental group may vanish, the founder effect can enhance the prevalence of some rare illnesses
When scientists caught 20 seals and used them to start a new population in the northwest pacific ocean, then the founder effect is most likely to have the least impact on this new population. Therefore, option C is correct.

Which letter indicates where the moon would be located during a lunar eclipse?
A. Position M
B. Position P
C. Position N
D. Position O
Answer:
B. Position P
Explanation:
If it is at "Position P", the Earth blocks the moon from the light from the sun, creating an eclipse.
Position P indicates the location of moon during a lunar eclipse. Hence, the correct statement is option B.
What is lunar eclipse?A lunar eclipse is a celestial event that occurs during a full moon phase when the Earth passes between the Sun and the Moon, thereby, casting its shadow on the Moon which makes the moon a reddish-brown or coppery color, hence the moon is called "blood moon" during lunar eclipse.
A lunar eclipse only occurs when the Moon is in full phase and aligned with the Earth and Sun and can be visible from anywhere on the Earth. The lunar eclipse can last for several hours.
During a lunar eclipse, when Earth passes between the sun and the moon, it casts its shadow on the moon. The point at the moon's orbit where it is passing through the Earth's shadow is represented by position P which results in lunar eclipse.
Therefore, Position P indicates where the moon would be located during a lunar eclipse.

HELP PLEASE!! Field test is done on the milkweed in the wild and the clothianidin content per plant was about 1 ppb. larvae spend days in the wild eating the milkweed. how is this different from the experimental conditions? how would you design an experiment to test these conditions?
Answer:
In the question it is given that the milkweed with clothianidin above the 1ppb concentration will result in less successful hatching of monarch butterfly eggs. Along with the data from the experiments, the exposure of clothianidin on the monarch habitats will lead to a decrease in the population of the monarch butterfly initially. Then in later generations if any mutation occurs and a resistant butterfly is developed then the population of the monarch butterfly will recover. But without this mutation the population size will be reduced and the size and weight of the butterfly will also get reduced.
