Here is data from a study on second-hand smoke and lung cancer: Ten thousand (10,000) people
that have lived with smokers for at least 10 years were studied. Seven hundred and forty (740) of
these people got lung cancer. Therefore, 7.4% of these people got lung cancer. Their conclusion is
second-hand smoke causes lung cancer. Do you agree or disagree with their conclusion? Explain
your answer by using ONLY the data provided in this question.
Answer:
I disagree
Explanation:
The data doesn't give enough info, were the people who lived with smokers, smokers as well? or were they clean off nicotine. Also the data presents itself stating the fact that second hand smoke will defiantly cause Lung cancer when in reality (as the data shows with only 7.4%) only a small percentage is affected by the smoke.

Question 8
To what domain does this organism belong?
Domain Eukarya
Domain Bacteria
Domain Animalia
Domain Archeology
Domain Fungi
Answer:
Domain Eukarya
Explanation:
It sort of looks like a seahorse. And if it happens to be a seahorse, it would belong to the domian eukarya because animals are made of animal cells, and a eukaryotic cell can be either animal cell or plant cell. So it only makes sense for it to belong to domain eukarya (only if it is animal/plant).

Answer:
most of the cell are transparent

A forest area is belag used for a new housing development. Most of the trees have been removed to make room for
the new houses, Predict the impact that this will have on the birds in the area.
The bird populations will stay the same because humans love birds,
The bird populations will decrease because humans see them as pests.
y The bird populations will increase because humans do not interfere with wild animals.
The bird populations will decrease due to competition for resources such as food and nesting sites.
Answer:
The bird populations will decrease due to competition for resources such as food and nesting sites.
Explanation:
Ecological succession can be defined as the process by which the biological structure of a community, i.e., the group of interacting populations of species that occupy a particular area, changes over time. Human activities such as, for example, deforestation in order to develop an urban ecosystem, can dramatically alter the process of succession and literally destroy the natural balance of biological communities. In this case, it is expected that human activities have a negative impact on bird populations by increasing intra and interspecific competence with other organisms for limited resources (i.e., food and nesting sites).

You perform an experiment using an aquatic plant to determine which color of light is most effective at driving photosynthesis. You take three plants, immersed under water, place plant A under blue light, plant B under red light, and plant C under green light. You notice bubbles coming off the leaves. More bubbles are coming from plants A and B, than plant C. How do these results determine which color of light is most effective at driving photosynthesis
Answer:
The plants producing more bubbles indicates that photosynthesis is more effectively driven by BLUE AND RED LIGHTS.
Please find explanation below.
Explanation:
According to this question, an experiment is being carried out to determine which color of light is most effective at driving photosynthesis. Three sets of aquatic plants (plants A, B and C) are used for this experiment. Plant A was placed under blue light, plant B under red light, and plant C under green light.
Photosynthesis is the process whereby plants manufacture their food (glucose) using sunlight energy. However, it is worthy to note that OXYGEN GAS is one of by-products of this metabolic process. Hence, as stated in this question, the bubbles noticed to be coming off the leaves is OXYGEN gas.
However, more products in a reaction denotes the fast rate of such reaction. Plants A and B produced more bubbles than plant C. This means that photosynthesis in plants A and B, which released more OXYGEN GAS as BUBBLES, is more effective under the blue and red light respectively.

if you break down the word interactions, it means ”the actions between.“ How would you define interactions between two species?
Answer:
Symbiosis is an interaction characterized by two or more species living purposefully in direct contact with each other. The term "symbiosis" includes a broad range of species interactions but typically refers to three major types: mutualism, commensalism and parasitism.

how many monads are present in a human cell that is in G1 of interphase?
Answer:
47.9
Explanation:
There are 46 monads in a human cell that is in G1 of interphase.
In humans, each somatic cell contains 23 pairs of chromosomes, thereby having a total of 46.A chromosome consisting of one chromatid is called a monad. When a chromosome contains two chromatids, it is called a dyad.In the G1 phase, the genetic material of the cell still has not been replicated.In conclusion, there are 46 monads in a human cell that is in G1 of interphase.

What is the elevation of hachure line A?
100 feet
50 feet
75 feet
125 feet
Because the incorrect answer was 100 feet (based on it being the first lower elevation than the last recorded elevation of 125 feet) And the question prior of What is the most likely elevation of X being 115 feet was also graded incorrect. Would the actual contour lines WITH the hachure lines ON THEM continue to elevate in C.I. 25 increments making the contour line that X is on, 150 feet and the contour line that A is on to be 175 feet? And then 125 feet would actually be the correct answer because it is the first lowest below 175 feet?
d) During Transcription, a nucleotide has been deleted. Explain the effect this will have
on DNA as well as what happens in each step along the way to a protein.
Answer:
this mutation may change the open reading frame of the resulting RNA sequence and its final product, which is a protein in the case that this gene is used to synthesize a messenger RNA (mRNA) sequence
Explanation:
During the transcription, a region of DNA named 'gene' is used as template to produce an RNA molecule, typically a primary transcript of mRNA (pre-mRNA). Subsequently, this pre-mRNA suffers a process named RNA processing in order to generate a mature mRNA which is finally used to create a protein by a process called translation. If a deletion occurs during transcription, it may change the open reading frame (ORF) of the resulting mRNA when the mutation occurs in an exon of the protein-coding gene (i.e., occurs a frameshift mutation), while this deletion may not have any effect if it is localized within the introns which are removed during RNA processing. A frameshift mutation will change the amino acids that are added to the nascent polypeptide chain during translation.
Which factors affect the gravitational force between two objects?
Answer: The size of each object and the space between them.
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

Now that we have studied the various types of vaccines, consider the current resurgence of diseases like the measles. How can we convince the general public and possibly even ourselves, that immunization is a necessary preventative measure for diseases that have serious complications? Is there a different schedule that we should consider? Are some forms of vaccines safer than others? Should we spread out the inoculation schedule to prevent confusion of a young person?
Answer:
Immunization is one of the most effective processes of preventing or treating dangerous disease. It should be told and advertise to the general public about the facts and importance of vaccination. Doctors and government should explain the reports and ratio that the people who are taking the vaccination in the proper dose and the right amount of vaccination are about 9 timeless likely to have to the other people. It is essential to get a proper dose and proper amount to avoid the development of resistance.
There are several forms of vaccine and they have a different schedule from each other. Every vaccine is safe but one needs to know the cycles, dose and amount of the vaccine. Yes, we should spread out the inoculation schedule to prevent confusion of a young person.
