Answer:
Alchemy was scientific, because it included observations and experiments
Explanation:
Scientific research is one that is done through a series not steps or methods. Observation and experiments are part of the steps in a scientific research.
Scientific research is done through investigation of various theories of science as well as formulating hypothesis. Scientists do not just resort to picking random answers concerning the phenomenons around us. They carry out investigations, observations, and would also formulate potential explanations for what is on ground, carry out experiments and then analyze their results to know if they are right or wrong.
Since the question says observation and experiments were done it is scientific

Compare and contrast Meiosis and Mitosis, how are they similar and how are they different?
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Answer:
1. meiosis require two nuclear division but mitosis requires only one nuclear division
2. meiosis produces four daughter divisions, and there are four daughters cell following cytokinesis. Mitosis followed by cytokinesis result in two daughter cells
3. in meiosis, the four daughter cells are haploid and have half the chromosome number as the parent cell. In mitosis, the daughter cell have the same chromosome number as the parent cell
4. in meiosis the daughter are genetically dissimilar to each other and to parent but in mitosis, the daughter cells are genetically identical to each other and to the parent.

The 6 kingdom system of classification enables biologists to group organisms according to
Answer:
The correct answer is -a common characteristic (in a logical manner)
Explanation:
The six kingdom classification is given by Woese et al 1977, the basis of this classification was the shared characteristic of organisms. These common characteristics include more than one character such as cell type ( prokaryotic or eukaryotic), type of nutrients (autotrophs, heterotrophs), type of reproduction, homologous or analogous organs, habitat, and many more.
All these traits or characters helped in grouping organisms in a logical manner and is one of the most acceptable classifications.
Thus, the correct answer is -a common characteristic (in a logical manner)

Answer:
New algorithms for estimating chlorophyll-a in the Spanish waters of the Western Mediterranean Sea from multiplatform imagery This manuscript proposes a set of multi-sensor chlorophyll-a empirical algorithms for improving current estimates of chlorophyll-a concentration in two distinct regions in the Mediterranean Sea.
Many studies in the area of cancer research are opening up new possibilities for cures and prevention measures. One area of research is directed at the effects that chlorophyll may have on cancer cells within the human body. Research is being conducted to investigate whether chlorophyll has important cancer fighting factors that may play a role in the destruction of cancer cells or whether it is an effective preventive agent.
Daily supplements of the chlorophyll derivative, chlorophyllin (CHL) can provide a way to prevent cancer by reducing DNA damage (Arbogast, 1995). The chlorophyllin copper complex (CHL) is a water-soluble version of chlorophyll and is a semi-synthetic prepared substance. CHL is the most common chlorophyll derivative used for cancer related studies (Chernomorsky, 1999). Most research was done using chlorophyllin because chlorophyll is chemically modified to chlorophyllin in the body during digestion. Chlorophyllin given in amounts to that of chlorophyll were equally effective in the studies (Sarkar, 1994). CHL can be added to the diet very easily and may be safe and useful for effective prevention of cancer (Arbogast, 1995).

The surface of rivers freeze when the temperatures falls below freezing. However, the water underneath this layer of ice continues to flow. This phenomenon allows fishermen to fish through holes drilled in the ice the entire winter. Which property of water is the reason the river doesn't freeze completely?
Answer: Water retains its temperature for long.
Explanation:
The ice floats on the water of river as it is less denser then the liquid water. This causes ice to float on water. It protects the water at the bottom from freezing. The decrease in the temperature level can cause the death of the marine life by catching organisms in the ice. The floating of the ice insulates the water present beneath. So, the fish and other aquatic animals can survive and the fishermen can catch the fishes alive.

A biomagnification
B greenhouse effect
C photosynthesis
D transpiration
The condition that is caused by carbon dioxide, methane, and water vapor trapping heat in the Earth's atmosphere is known as the greenhouse effect. Thus, the correct option is B.
What is the Earth's atmosphere?The earth's atmosphere may be defined as the significant presence of a layer of various gases that surrounds the whole planet. It is known that the Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
Carbon dioxide, methane, and water vapor are considered greenhouse gases that ultimately capture the heat radiations from the sun and liberate the earth's atmosphere. As a result of this, the average temperature of the earth's surface has gradually increased for four to five decades.
This is all known as the greenhouse effect. The Greenhouse effect may be defined as the phenomenon of keeping the earth warm due to the presence of certain gases in the atmosphere that captures heat from the sun.
Therefore, the condition that is caused by carbon dioxide, methane, and water vapor trapping heat in the Earth's atmosphere is known as the greenhouse effect. Thus, the correct option is B.

Which of the following is NOT a characteristic of active transport? *
A)It moves substances against a concentration gradient
B)It requires energy from the cell
C)It involves facilitated diffusion
D)It may use carrier proteins that often function as the sodium potassium pump
Answer:
It involves facilitated diffusion.
Explanation:

Changing the shape or morphology of the mitochondrial inner membrane can change the efficiency of mitochondrial function.
Which of the following outcomes will most likely result from a change in the shape of the mitochondrial inner membrane from a highly folded surface to a smooth, flat surface?
Since, the options have not been given the question is incomplete the complete question is as follows:
Changing the shape or morphology of the mitochondrial inner membrane can change the efficiency of mitochondrial function.
Which of the following outcomes will most likely result from a change in the shape of the mitochondrial inner membrane from a highly folded surface to a smooth, flat surface?
A. Mitochondria will become more efficient because the inner mitochondrial membrane will become more permeable to ions.
B. Mitochondria will become more efficient because the total volume of the mitochondria will increase.
C. Mitochondria will become less efficient because the inner mitochondrial membrane will become less permeable to large molecules.
D. Mitochondria will become less efficient because the surface area of the inner mitochondrial membranes will decrease.
Answer: D. Mitochondria will become less efficient because the surface area of the inner mitochondrial membranes will decrease.
Explanation:
Mitochondria is called the power house of the cell as it produces energy by the oxidation of food in the form of adenosine triphosphate or ATP. The inner mitochondrial membrane comprises of numerous folds which are called cristae which increases the surface area for the chemical reactions necessary for the production of energy. If the folding increases the surface area for energy production will decrease as the surface area for chemical reactions will decrease. Thus the efficiency of mitochondria will decrease.
If the mitochondrial inner membrane becomes flat or smooth surface then this also decreases the surface area for chemical respiration, thus in this case too the efficiency of mitochondria will decrease.

Damage to the auditory nerve or to the hair cells in the inner ear results in
A. Ménière's disease
B. sensorineural hearing loss
C. conductive hearing loss
D. otitis media
Please select the best answer from the choices provided
Answer:
B. sensorineural hearing loss
Explanation:
Damage to these hair cells results in decreased hearing sensitivity, and because the inner ear hair cells cannot regenerate, this damage is permanent.
Damage to the auditory nerve or to the hair cells in the inner ear results in sensorineural hearing loss. Thus, the correct option is B.
What is the Auditory nerve?The auditory nerve may be defined as a cluster of nerve fibers that transport hearing information between the cochlea and the brain.
When the auditory nerve or hair cells are damaged due to any injury or other reasons, it can lead to a reduction in hearing sensitivity.
The cells of this region are unable to regenerate, and hence this damage will remain permanent, and sensorineural hearing loss will result in this scenario.
Therefore, the correct option for this question is B.
