Earth is made of different layers that have varying characteristics. Which is the thickest layer?
Answer: the mantle is the thickest layer,
Explanation:
Populations can have variety, despite being made up of
the same species. If a population has different expressed
traits, this can be due to different inherited alleles. The
frogs below are the same species, but they have different
shades of green based on their inherited alleles. In a
particular environment, lighter green frogs are easier to see
by predators. Explain how natural selection could lead to a
change in allele frequency.
Answer:
The lighter frogs will be eaten and will not be able to reproduce offspring with the light green trait. Darker green frogs will be able to reproduce more dark green frogs. Eventually most/all frogs will be a darker green because they carry a trait that improves chances of survival.

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.

Which statement is true regarding meiosis in cells?
O In anaphase I, sister chromatids are pulled apart at the centromere.
O In prophase II, homologous chromosomes are paired up in a tetrad.
O The daughter cells do not undergo cytokinesis at the end of meiosis
The products of telophase I are two haploid daughter cells..
answer : the last one is true, yeah !!
d :: the products of telophase 1 are two haploid daughter cells ..
Chromosomes finish migrating to opposing ends of the cell in telophase I. Cytokinesis then creates two daughter cells. Therefore,option (D) is correct.
What happens is telophase I?The parent cell has two poles at Telophase I of the meiotic cycle, each with a full complement of haploid chromosomes (which still have their sister chromatids). Now, a cleavage furrow forms, separating the cytoplasm of the cell in two (a proccess ultimately called cytokinesis).
The homologous chromosomes divide into distinct nuclei during telophase I. The cell restores its nuclear membrane, deconstructs the microtubules and spindle fibers, and then initiates cytokinesis. After then, the cell enters a phase of rest known as interkinesis.

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

What is the main function of the Krebs cycle?
A. To break glucose down into two pyruvate molecules
OB. To produce carbon dioxide for use in the thylakoid
O C. To produce large numbers of ATP molecules
O D. To provide molecules for the electron transport chain
Answer:
O D. To provide molecules for the electron transport chain
Explanation:
The Krebs cycle, also known as the citric acid cycle, refers to a series of reactions during cellular respiration that produces energy by the oxidation of acetyl-CoA. The Krebs cycle utilizes acetyl-CoA and water in order to reduce the cofactor Nicotinamide adenine dinucleotide (NAD) to NADH, in a process that releases carbon dioxide (CO2). This NADH is then used by the oxidative phosphorylation electron transport pathway in order to generate ATP, the energy coin of the cell.
