explain the importance of understanding genetics and heritability. what might a geneticist study and how could that help living things on earth? use specific examples and include the basic structure of function of genes
Answer:
Heritability is a measure of how one person differs from the other based on their genetic make up. Differences in genes or their make up leads to differences in their traits or characteristics such as height, eye color, and intelligence. Genetics and its applications have a wide variety of applications serving the human mankind. This includes the detection of many diseases like cancer at early stages,treatment of diseases, forensic applications with DNA fingerprinting, Cross breeding in both plants and animals to obtain high quality products with desired traits like, taste, fertility, size, disease resistance etc. Genetic enineering and Biotechnology has carved a niche of its own in th field of Science these days and is a promising feild which would address many problems faced by the world today.
Gene structure is the organisation of specialised sequence elements within a gene. Genes contain the information necessary for living cells to survive and reproduce. In most organisms, genes are made of DNA, where the particular DNA sequence determines the function of the gene.
Genes are what is inherited from an organism's parents and what give the offspring certain characteristics of the parents, and alleles are different forms of a gene. For example, there are several different alleles for eye color genes, such as blue alleles (blue eyes) and brown alleles (brown eyes).
Explanation:
A genomic sequencing method called _______ sequencing was used in the human genome project. In this method, DNA is broken into many small fragments and the fragments are sequenced, then computers help reassemble the fragments into the larger DNA sequence
Answer:
Shotgun Sequencing
Explanation:
Shotgun sequencing is a laboratory technique for determining the DNA sequence of an organism's genome. The method involves breaking the genome into a collection of small DNA fragments that are sequenced individually. A computer program looks for overlaps in the DNA sequences and uses them to place the individual fragments in their correct order to reconstitute the genome.
Answer:
1. shotgun
2. inbreeding
3. cloning
4. Y chromosomes
5. The Human Genome Project sought to map a human's entire genome.
6. Inbreeding is a type of selective breeding that occurs when individuals with similar characteristics continue to be bred in an attempt to keep a certain set of traits. However, inbred organisms are genetically similar, and the probability that members of the population will receive mutated alleles leading to disorders is high.
7. Since no two humans have the same DNA, except for identical twins, forensics can take advantage of this fact by using DNA fingerprinting to solve crimes, convict wrongdoers, or overturn unjust convictions.

Meiosis can be best described as the event which occurs only in the cells which are the part of reproductive structures in an organism. Thus, the correct option is B.
What is Meiosis?
Meiosis is a type of cell division which occurs in sexually reproducing organisms. It is also known as reductional division as in this division, the chromosomal number is reduced to half. This division is responsible for introducing genetic variations in a population.
Meiosis is a type of cell division which occurs in the sexually reproducing organisms. This division is responsible for reducing the number of chromosomes in the gametes or sex cells such as eggs and sperms by half. In humans, normal body cells or somatic cells are diploid in nature. These cells contain two sets of chromosomes i.e., one from each parent.
Therefore, the correct option is B.

How do the geography and geographical features of your area affect the temperature?
Answer:
An area's latitude on the surface of the Earth affects the weather because it changes the intensity of the sun's light that the area receives. Things like mountains affect the weather by directing air currents, which can send storms to you, or keep them away. If you live in a place with lots of vegetation, it will be more humid, and warmer, because the plants retain the heat.

How does natural selection lead to evolution?
a
Environmental changes kill weaker members of the species.
b
Stronger offspring kill weaker members of the species.
c
Overproduction provides food for stronger members of the species.
d
Helpful traits accumulate among surviving members of the species
Answer:
The correct answer is option b. "Helpful variations accumulate among surviving members of the species".
Explanation:
Natural selection is the most accepted theory of evolution, described by Charles Darwin in 1859. This theory explains that by the survival of the fittest, the helpful variations accumulate among surviving members of the species. The variations or mutations that are not helpful for the species are lost by predators and environmental factors, while the helpful variations remain in the surviving members, which leads to the species evolving to have improved characteristics.

Unit 2 Short Answer Question (Do NOT leave blank): Use the following words to fill in the blanks: transcription, dairy products, enzymes, proteins, repressor, rna polymerase, lactose intolerant, lactase, operator, ecoli, transcribe, bases, repressor, operator.
An example of prokaryotic gene expression is the lac operon. When a person is 1)____________, they do not produce the enzyme 2)___________, which aids in the digestion of lactose, the sugar found in 3)______________. If a person who is lactose intolerant eats or drinks a dairy product, lactose travels down the digestive tract into the large intestine, where the genes in the bacteria, 4)__________ , are turned on to create the 5)_______ / 6)________ needed to digest the lactose. In E.Coli, when lactose is present, it acts as an inducer and binds to the 7)____________ protein, keeping it from attaching to the 8)___________. 9)_____________ then is able to attach to and 10)___________ the E.Coli gene by matching up the 11)______. When lactose is NOT present, the 12)____________ protein binds to the 13___________ and transcription is blocked. This is an example of gene expression (production of proteins) being controlled at 14)_____________.
Answer:
1. lactose intolerant
2. lactase
3. dairy products
4. E.coli
5. enzymes
6. proteins
7. repressor
8. operator
9. RNA polymerase
10. transcribe
11. bases
12. repressor
13. operator
14. transcription
Explanation:
Lac operon is good example of prokaryotic gene regulation. The lactose operon or lac operon is a type of operon which is use to transport and metabolize the lactose in E.coli and other bacteria. The lac operon is made up of three important components including promoter, an operator, and three genes that encode the enzymes required for lactose digestion.
A person who is lactose intolerant is unable to produce the enzyme lactase, which helps in the digestion of sugar generally present in dairy products. The lac operon is regulated by lactose in the environment.
So, when lactose intolerant people consume dairy products, the gens in bacteria E.coli present in the large intestine, turn on to produce enzyme or proteins required to digest the lactose.
When lactose is present, lac operon in E.coli, acts as an inducer and binds to the repressor protein which prevent it binding to the operator. RNA polymerase the binds to the promoter and transcribe the E.Coli gene by matching the base pair or bases.
When lactose is absent, repressor protein is allow to bind to the operator and inhibit the transcription process in E.Coli. The whole process is regulated during transcription in prokaryotes that involves lac operon.
Hence, the correct words for the blanks are as following:
1. lactose intolerant
2. lactase
3. dairy products
4. E.coli
5. enzymes
6. proteins
7. repressor
8. operator
9. RNA polymerase
10. transcribe
11. bases
12. repressor
13. operator
14. transcription

Which outcome would most likely suggest that data collected is unreliable?
A.)Other scientists conduct the same study but find different data.
B.) The data is put on a scatterplot but does not show any trend.
C.)Each data point is considered by many scientists to be accurate.
D.)Many tools were used in the same laboratory to measure the data.
A.
Let's break it down:
-If the study has been conducted by multiple others and they get different results, it might be a sign that something went wrong in the experiment, and the data is unreliable. For example, if everybody else timed an event and got the same exact time except for the fact that you got a different time, you may start to suspect that you had done something wrong and the data was unusable.

What is the difference between dominant and ressesive trait
Answer:
When an allele is dominant, the characteristic it is connected to will be expressed in an individual. When an allele is recessive, the characteristic it is connected to is less likely to be expressed. Recessive traits only manifest when both alleles are recessive in an individual.
Explanation:
Dominant means that one of the versions trumps the other. In our example here, brown is dominant over blue so you end up with brown eyes.
The way people write out dominant and recessive traits is the dominant one gets a capital letter and the recessive one a lower case letter. So for eye color, brown is B and blue is b.

What did Malthus think would limit the population size?
A. Food supply
B. Predators
C. Disease
D. Reproductive strategy
Answer:
A Food Suply
Explanation:
Malthus believed that the population size would be limited by the availability of food supply. He argued that while populations have the potential to grow at a geometric rate, the food supply could only increase at an arithmetic rate. Hence option A is correct.
How to limit the population size?There are various ways to limit population size, some of which include:
Birth control: Providing access to contraception and family planning services can help to control birth rates and reduce population growth.
Education: Educating people, especially women, about the benefits of having smaller families can also help to reduce population growth rates.
Economic incentives: Providing economic incentives, such as tax breaks or financial rewards for having smaller families, can also help to limit population growth.
Malthus believed that this was a natural and inevitable process and that efforts to alleviate poverty and suffering would only lead to more population growth and ultimately exacerbate the problem.
This means that the population would eventually outgrow the available food supply, leading to famine, disease, and ultimately population control through natural selection.
Hence option A is correct.

A science teacher wants to use a line graph to model the relationship between the concentration of CO2 in the atmosphere and the global temperature from 1960 to 2017.
What would the graph show?
A)
global temperature increasing as CO2 concentration increases
B)
global temperature increasing as CO2 concentration decreases
C)
global temperature decreasing as CO2 concentration increases
D)
global temperature stabilizing as CO2 concentration increases
Answer:
A)
global temperature increasing as CO2 concentration increases
Explanation:
Global warming is the progressive increase in the temperature of the earth's atmosphere. Global warming is caused by an increase in the concentration of greenhouse gases e.g CO2, chlorofluorocarbons etc. These greenhouse gases, in which carbondioxide is an important example, are capable of trapping heat in order to keep the earth warm.
Howeever, as the concentration of CO2 and other greenhouse gases increase in the atmosphere, the earth's atmospheric temperature also increases above normal, causing Global warming.
In this case, the science teacher's graph will show that global temperature is increasing as CO2 concentration increases.
