How do DNA sequences eventually lead to traits?
Answer:
Traits are determined by genes so it's the manifestation of a gene coded for the DNA :3
Explanation:
:3
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_.

Which statement describes natural selection
Answer: You didn't put any statements lol
Explanation:
But basically natural selection is when organisms with the most favorable traits will survive and reproduce. (ex. there are 2 strains of bacteria - one that resists antibiotics and one that doesn't. The one that resists the antibiotics will strive and reproduce because that will be the more favorable trait that will be able to be inherited by future generations.)

11. Why is the age of the earth important to Darwin's theory of evolution?
Answer:
Darwin's theory of evolution is when species are taking time to evolve from the original organism so in order for this to happen there has to be an original species so he also said that we came from apes if the world was 200 years old that still wouldn't be enough time for us to evolve how he said so in order for his theories to be even remotely correct it took time for this to happen so the age of the earth in a way helps support his theory

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.

What process breaks glucose down to be used as an energy source?
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.
