Explanation:
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.

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.

Scientists have linked the human genome to a parts list. Explain what they mean. What other analogy (comparison) can you make?
Answer:
The pieces can be represented by genes
Explanation:
It has been shown that the human genome contains more than 30 thousand protein‐coding genes, as well as transposable elements, repetitive and non-coding RNA sequences. These protein-coding genes are in turn composed of coding regions (exons) separated by non-coding regions (introns). The analysis of the human genome enables the scientists to identify genes associated with specific signaling network pathways and diseases.

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.

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.

Explain how scientists got the space station up in space. What problem did they
encounter and how was it solved?
Answer:
scientists got the space station up in space in to small pieces.
Explanation:
The main problem which was faced by the scientist was that there was no powerful rocket which has the ability to lift the whole space station due to its more weight and carry it to the space against the powerful force of gravity. So for solving this problem, space station is taken into pieces into the space and then these pieces should be join to build the space station.
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.

Imagine if the population in your neighborhood suddenly doubled in size. This increase
would put a strain on transportation, food, and electricity. What steps might the
neighborhood take to relieve these problems? Are there any consequences to taking these
steps? Write your answer in one or two short paragraphs.
Answer:
An increase in population leads to more cars on the road. That could clog the roads. Adding extra lanes of traffic and roads could help address this problem. But roads cost a lot of money and might require clearing away valuable natural resources. More people also means the demand for food will increase. People will have to grow more crops, or cities will have to provide more ways to get groceries. Growing more crops and setting up grocery stores will cost money and use up land, just as adding roads does. A larger population also puts a strain on utilities, such as electricity. Increased demand may result in the depletion of fossil fuels, which can interfere with the fuel needs of future generations. Investments in clean energy could help limit this effect.

What needs to be provided for humans and machines?
Answer:
First of all, The average temperature of outer space near Earth is 283.32 kelvins (10.17 degrees Celsius or 50.3 degrees Fahrenheit). In empty, interstellar space, the temperature is just 3 kelvins, not much above absolute zero, which is the coldest anything can ever get. Also, space is a vacuum, which means that you would suffocate. Space's environment is also very radioactive. Also, there is no pressure in space, So you would boil, fry, suffocate, and explode at the same time. Suits must be provided to create a safe environment in space.

Explanation:
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).
