Scientists have linked the human genome to a parts list. Explain what they mean. What other analogy (comparison) can you make?
Answers
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.

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
Answers
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).

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.
Answers
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.

A: plant-like protist
B: animal-like protist
C: archaea
D: bacteria
E: fungus-like protist
Answers
Answer:
animal-like protist
Explanation:
plato
Protozoans are classified as animal-like protists. Therefor, option (B) is correct.
What are protozoa?Protozoa are single-celled eukaryotic organisms that belong to the Kingdom Protista. They are typically found in water, soil, and as parasites in plants and animals. Protozoa are classified based on their method of movement, morphology, and mode of nutrition. Some protozoa are motile and use flagella, cilia or pseudopodia to move, while others are non-motile.
Protozoa are classified into four major groups: amoebae, ciliates, flagellates, and sporozoans. Amoebae move by extending pseudopodia or "false feet," which allows them to crawl and engulf food. Ciliates use hair-like projections called cilia for movement and have a distinctive micronucleus and macronucleus in their cell structure. Flagellates use whip-like flagella to move and are often found in aquatic environments. Sporozoans, on the other hand, do not have any means of independent movement and rely on a host to survive.
Some protozoa can cause diseases in humans and animals, such as malaria (caused by Plasmodium), sleeping sickness (caused by Trypanosoma), and amoebic dysentery (caused by Entamoeba histolytica). Despite their small size, protozoa play an essential role in the food chain as primary producers and decomposers.

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.
Answers
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 is the difference between dominant and ressesive trait
Answers
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.

When a wave reaches a beach or coastline, it releases a burst of energy that generates a current, which runs parallel to the shoreline. This type of current is called a longshore current. The water in a longshore current flows up onto the beach, and back into the ocean, in a sheet formation. This action can cause significant beach erosion called A) ripping Eliminate B) parallel erosion C) longshore drift D) longshore rip
Answers
Answer:Longshore drift
Explanation:
Longshore drift which originates from longshore current is a geological process which involves the movement of sediments eg pebbles, sand along a coast in one direction which is determine by a prevailing wind, and so generates a water current which moves parallel to the shoreline at about 45 degrees.

Why do some scientists think that global warming would increase the
strength of hurricanes?
A. Hurricanes could form in areas currently covered by glaciers.
B. Hurricanes rotate faster during summer months.
C. Hurricanes get their energy from the warmth of oceans.
D. Hurricanes would gain strength from heated landmasses
Answers
Answer:
C. Hurricanes get their energy from the warmth of oceans.
Explanation:
Global warming is defined as a gradual rise in the earth's temperature caused by the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
What are hurricanes?Hurricanes are massive storms with rotating wind speeds of 74 miles per hour. The rotating wind blows with terrifying force across the warm water of the tropics. This force washes ashore, causing destruction and even death. Hurricanes are known as one of nature's most destructive storms because of the damage they cause.
Thus, we can conclude that in option C, Hurricanes get their energy from the warmth of oceans because Hurricanes form over relatively warm sea surfaces, which has led to speculation that global warming will significantly increase hurricane activity.

c
Overproduction provides food for stronger members of the species.
d
Helpful traits accumulate among surviving members of the species
Answers
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.

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
Answers
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.
What did Malthus think would limit the population size?
A. Food supply
B. Predators
C. Disease
D. Reproductive strategy
Answers
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.
