How is salinity affected when precipitation increases
Answer:
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.

Astronomers use a wide variety of technology to explore space and the electromagnetic spectrum; why do you believe it is essential to use many types of equipment when studying space?
It is essential to use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space. Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study. Tools are useful, such as detectors that help see the different wavelengths of light. Not all light can get through the Earth's atmosphere, so for some wavelengths we have to use telescopes aboard satellites.
If carbon was the most common element found in the moons and planets, what element is missing that would make them similar to Earth? Explain why. (Hint: Think about the carbon cycle.)
The missing element that would make moons and other planets similar to earth is oxygen. The two make carbon dioxide.

Explanation:
Answer:
1. Using two to three sentences, summarize what you investigated and saw in this lab.
I found that most of the planets and moons had carbon in them and that different elements absorb different wavelengths of light.
2. Astronomers use a wide variety of technology to explore space and the electromagnetic spectrum; why do you believe it is essential to use many types of equipment when studying space?
Astronomers should use multiple space technologies to study space objects. Although most light is similar, the way astronomers investigate light depends on what spectrum they want to see. Not all light can make it through earth’s atmosphere, so some wavelengths must be measured with telescopes on satellites.
3. If carbon were the most common element found in the moons and planets, what element is missing that would make them like Earth? Explain why. (Hint: Think about the carbon cycle.)
The missing element would be oxygen because the two of them make carbon dioxide.
4. We know that the electromagnetic spectrum uses wavelengths and frequencies to find a lot about outer space. How does it help us find out the make-up of stars?
Astronomers study the wavelengths by putting telescopes in high-up areas and getting the results of what they have observed.
5. Why might it be useful to find the elements that a planet or moon is made up of?
It might be useful so that we can discover new life on other planets and moons, or even discover new moons and planets.

Identify a point source and a non-point source pollutant in your environment. Write a short report discussing these pollutants.
Answer: Point source pollutant: My school is situated near a river. A wastewater treatment plant is a few miles away. The plant uses certain chemicals to treat wastewater, but releases effluents into the river. Although the plant regulates the released effluents, the treatment system gets overloaded during heavy rainfall. As a result, untreated chemicals and wastes enter the river. The plant thus becomes a point source pollutant for the river. The wastes and chemicals entering the river adversely affect growth of plants and fishes in the water body.
Non -point source pollutant: I live in a residential area that has a groundwater reservoir. Last month, the authorities in my area complained that the water in the reservoir was getting polluted. On investigating, they found that rainwater picks up debris and pollutants from roads and sidewalks as it flows on its path. The polluted water enters waterways that are connected to the groundwater reservoir. The debris and pollutants are many in number, and it was difficult to trace exactly where the rainwater picked them up. However, these pollutants affect large areas because the water from the groundwater reservoir reaches many homes. Therefore, the debris and pollutants are non-point source pollutants.

How can evolutionary change in one species lead to evolutionary change in another species that it is associated with? Include an example to support your answer.
Evolutionary change in one species lead to evolutionary change in another species that it is associated with by adaptive mechanisms.
What is evolution?Evolution is a process of gradual cumulative changes which occurs in organisms over a long period of time resulting in the formation of new species.
Evolution in one species results in evolution in a closely related species. For example, the evolution of resistance by trees to insect pests results in similar evolution in insect pest for development of mouth parts that enables them to feed on the plants.
Therefore, evolutionary change in one species lead to evolutionary change in another species that it is associated with.

Our eye color, hair color, or if we have freckles or not, are all considered (4)___11. The traits that we inherit
are determined by small segments of DNA called (5). We get these features from our parents; the
transfer of traits from parents to offspring is called (6)_____. Some traits are always seen if they are
inherited, and these are called (7)___... Brown eyes are an example of this type of trait. Blue eyes,
however, are an (8)___ trait and are only seen in the absence of a dominant trait.
Answer:
(4) traits
(5) genes
(6) heredity
(7) dominant
(8) recessive
Explanation:
Traits are inherited, and coded by genes. Genes are DNA segments placed in chromosomes. Alleles code for different expressions of the same trait. 4) trait / 5) gene / 6) heredity / 7) dominant / 8) recessive.
---------------------------------------
We know that phenotype is influenced by genotype and the action of the environment.
Part of an individual's phenotype is due to the genotype -inherited by the parents-, and the other part is due to the environment, where the individual develops.
According to this, inheritability might be defined as the proportion of phenotypic variation that might be due to genetic effects.
Regarding the genetic factor, inheritability is conditioned to heredity.
Heredity might be understood as the process of transmission of different characteristics through generations.
Morphological and behavioral characteristics are traits.
Genes are the hereditable DNA fragments that transmit the information needed to specify traits. This information passes from parents to offspring, generation to generation.
Genes are physically placed and arranged in the chromosomes. Each chromosome contains many genes that might vary in length.
Genes are inherited and define the individual's phenotype.
Alternative forms of genes -alleles- is what determine the phenotypic variation.
Each individual inherits a set of genes from each parent that combine during fertilization.
According to this combination, each individual will express a phenotype that is the product of a mixture between both parents' genetic charges.
According to Mendel, each individual has a pair of factors -alleles-, and each factor codes for an alternative form of the same trait -for instance, tall and short-. He thought that these factors separate -segregate- during gamete formation.
In complete dominance, the dominant allele completely masks the recessive allele effect. This is evident in heter0zyg0us individuals that only express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
Knowing this, we can complete the sentences.
Our eye color, hair color, or if we have freckles or not, are all considered (4) _CHARACTERISTICS or TRAITS_The traits that we inherit are determined by small segments of DNA called (5) GENES .We get these features from our parents; the transfer of traits from parents to offspring is called (6)_HEREDITY_. Some traits are always seen if they are inherited, and these are called (7)_DOMINANT TRAITS_. Brown eyes are an example of this type of trait.

If the average length of a double helix in human chromosome is 3.9 cm, approximately how many base pairs are present in such chromosome?
Answer:
The average length of a double helix in human chromosome whose length is 3.9 cm has approximately 114.7 million base pairs
Explanation:
Lenght of DNA = number of base pairs * distance between consecutive base pairs
The distance between two consecutive base pairs bonded by hydrogen bonds is 0.34 nm.
If the average length of a double helix DNA molecule in human chromosome is 3.9 cm, the average number of base can then be calculated using the formula below:
Average number of base pairs = length of DNA ÷ distance between consecutive base pairs
Average number of base pairs = 3.9 cm/ 0.34 nm = 0.039 m/ 0.00000000034 m
Average number of base pairs = 114705882.4
Therefore, the average length of a double helix in human chromosome whose length is 3.9 cm has approximately 114.7 million base pairs
