Answer:
It is not possible to determine the dominance or recessivity of DNA/protein sequences without prior phenotypic data. This means that it is imperative to obtain phenotypic information to be associated with a given molecular sequence.
Explanation:
Dominant and recessive are two different phenotypic variants of the same trait which may be associated with different forms at the gene level (alleles). In a diploid organism, the trait that is observed in the heterozygous organism is called dominant; while the trait that is masked is named recessive. In consequence, the only way to determine the effects of one gene (or its encoded protein) is by observing the phenotype expressed from this sequence.

Experiment: What is the effect of drinking coffee on a person's score on a memory test?
Which of the following would be the INDEPENDENT VARIABLE?
O Coffee
O Decaf coffee
O Memory test score
O Type of cup used
Answer:
The independent variable would be the coffee.
Explanation:
In an experiment, the independent variable is something that is added or changed by the scientist in order to see if there will be a response.
In this case, the memory test score would be the dependent variable (something that changes as a result of a change in the independent variable).
Decaf coffee could be a control group, or a group that is treated the same as the independent variable but without being exposed in order to account for any outside factors.
Finally, the type of cup used would be a constant between the control group (using the decaf coffee) and the experimental group (the group with regular coffee).

name four cycles that help to recycle matter in the biosphere
Answer:
Nitrogen cycle
Carbon cycle
Sulfur cycle
Phosphorus cycle
Explanation:
The material cycle refers to the pathway through which important materials in the biosphere take from their source of production to where they are utilized and back to their source of production. It can also be defined as the pathway by which important materials move between the living and non-living components of the earth.
The important materials include nitrogen, carbon, sulfur, phosphorus, etc. The cycles that help to recycle these materials are named according to the name of the material. Hence, there is a nitrogen cycle, carbon cycle, sulfur cycle, and phosphorus cycle respectively.

List 3 sources of evidence for the endosymbiotic theory.
Answer:
DNA, RNA, Ribosomes And Protien Synthesis.
The endosymbiotic theory states that mitochondria and chloroplasts in eukaryotic cells were once prokaryotes engulfed by an early eukaryote.
The lines of evidence for this theory include:
Both mitochondria and chloroplasts have their own DNA that resembles DNA from prokaryotic organisms (i.e., a circular DNA molecule).Both mitochondria and chloroplasts have bacteria-like ribosomes.Both mitochondria and chloroplasts have a double membrane structure, i.e. an inner membrane and an outer membrane.Mitochondria and chloroplasts have a similar size as prokaryotic cells.In conclusion, the endosymbiotic theory is a well-supported theory and states that mitochondria and chloroplasts were once prokaryotes that were engulfed by an early eukaryote.

If you were to decide to remove outlying data points from you analysis what are two ways you could indicate this in your report to ensure you are being honest about you data analysis
Answer:
If the outlying data points are to be taken out from the report to guarantee the analysis of examination is right is to eliminate only if that isn't right or if there is enough data to check the data points once more.
One shouldn't eliminate outliers if the outcomes are critical and there are numerous outliers in data point. While eliminating the data points, one can trim the data points or change it with closest with mean or median.
Explain the importance of geoneutrinos to understanding earth’s interior
Answer:
“Geoneutrinos,” neutrinos that stream naturally from the Earth’s interior, are giving scientists the best direct evidence of what’s at work in the belly of the planet. Released by naturally occurring radioactive isotopes inside the Earth, geoneutrinos carry information about what makes the Earth’s insides hot; what elements make up the core of our planet and in what concentration and distribution; how the Earth’s mantle and tectonic plates move and interact; and how planets like our own form and evolve.

Which variable is measured in an experiment?
dependent variable
experimental variable
independent variable
The Dependent variable is measured in an experiment. Thus, the correct option is A.
What is a Dependent variable?A dependent variable may be defined as a form of variable in experimental studies that never stands alone. The value of this variable significantly depends upon the independent variable.
The fluctuation in the independent variable may typically induce the dependent variable to be altered. It is the variable that is being measured or tested in a scientific experiment.
While the independent variable is one that stands alone in a given set of experimental studies descriptively. Its value does not depend on any sort of other variables. While the experimental variable is not frequently observed in any experimental analysis.
Therefore, the Dependent variable is measured in an experiment. Thus, the correct option is A.

Question 5 (4 points)
Which is a correct statement regarding microscope use?
You should always begin with the lowest power objective lens.
This highest power objective lens is generally the shortest one.
You should always start with the highest power objective lens.
Once you center under low power, you will not recenter again.
Answer:
Once you center under low power, you will not recenter again.
Explanation:
The correct option would be that once you center under low power, you will not recenter again.
One can start focusing a slide using the x10 or x40 objectives, it does not have to always be the x10 objective and it is never advisable to start with the highest power objective. Also, the highest power objective lens is the longest and not the shortest one.
However, once the field diaphragm has been centered under low power, one does not need to center again but only to refocus.

How do you think plant cells differ from animal cells
Answer:
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast. Once the sugar is made, it is then broken down by the mitochondria to make energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.
Both plant and animal cells have vacuoles. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles.
Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.

Which of the qualities listed below explain why certain organisms are classified as indicator species? They are a primary food source for many other organisms B. They are very sensitive to environmental change. C. They can't easily escape pollutants D. All the above
Answer:
B. They are very sensitive to environmental change
Explanation:
Certain organisms like plants, animals and microbes are used to monitor pollution status of the environment. These organisms are called indicator species or bioindicators. They are widely used for pollution monitoring due to their sensitivity to environmental changes i.e. in the presence of a pollutant, they undergo morphological or physiological changes.
A common example of indicator species is the proliferation of algal species in a water body known as ALGAL BLOOM. They tend to grow excessively in the presence of pollutants in form of nitrates and phosphates which they use as nutrient.
