) A field biologist finds an unfamiliar single-celled organism in a sample from the surface of a marshy area. What observations or tests would make it possible to determine whether it is a protozoan, fungus, or alga
Answer:
Genetic analysis, structure analysis and study the behaviour.
Explanation:
Genetic analysis, structure analysis and study the behaviour of organisms are the observations or tests that would make it possible to determine whether it is a protozoan, fungus, or algae because these analysis provides information about the genetic makeup and structure of their cell. If the cell wall is made of chitin then it is considered as fungi, if the cell wall is made of peptidoglycan then it is an algae and if the cell wall is not present then it is considered as animals like protist.

Why do you think during the evolutionary process there was a correlation between brain size increasing while cecum size decreased in the omnivores?
How does insect respiration differ from that of vertebrate respiration? How do they manage to respire?
Answer:
Brain size increase due to find out improved quality diets whereas cecum size decrease due to reduction of its need.
Explanation:
Brain size increased due to the need to increase the mental capacity of an organism in order to explore the environment for the survival such as search for improved quality diet and the cecum size decreased because omnivorous diet improved due to the reduction of its need as a component of the digestive system. Insects have different respiration system as compared to vertebrates because vertebrates uses lungs for respiration whereas the insects uses tracheal tubes for the absorption of oxygen and removal of carbondioxide gas.

100% in the test ;)
Humus is made of Earthworms, nutrients and bacteria. So, the correct options are A, B and C.
What is Humus?Humus is the soil's black organic material that results from the breakdown of plant and animal debris. It is a type of organic material for soil. It has a lot of nutrients and keeps the soil moist. The Latin word for "earth" or "ground" is humus.
Humus is described as a dark organic substance that develops in soil as a result of plant and animal debris decomposing. It is organic and dark in colour because carbon has accumulated there. It contains elements that are crucial to maintaining healthy soil. Earthworms, nutrients, and microbes make up humus.
Because humus is a feature of loamy soils, the high concentration of nutrients in the soil is caused by humus. Humus reduces a substance's porosity by obstructing the pores that permit the passage of water and air.
Therefore, the correct options are A, B and C.

Why do scientists use microscopes to study cells?
A. Because most cells are too dangerous to view without protection
B. Because it is quite rare to find living things that are made of cells
C. Because most cells cannot be seen without magnification
D. Because cells can be studied only after they have died
SUBMIT
Answer:
C
Explanation:
Most are too small to be seen with the naked eye. so they must be looked at with a microscope
The answer is C) Because most cells cannot be seen without magnification
Without the proper tools, the naked eye will never be able to see a cell. But when you have the correct tools, you will be able to spot them, as long if you know what you are doing. Cells are too small for the naked eye to see, just like trying to find the needle in the haystack without touching it.

Discuss the origin of the Neandertals in terms of biological adaptation and other forces of evolution.
Answer:
Neandertals are closest relative to modern humans as their large brains size had to do with their meat diets. There were many theories including the Allens theory or Bergman theory their larger nasal apertures to cold environments.
Smaller bodies are adapted to more hot climates, and larger bodies are adapted to more cold climates as per Bergman's rule. Allen's rule says that the principle that limbs are longer in hot environments and shorter in cold environments.
in order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many ___ bonds
Answer:
In order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many hydrogen bonds
Explanation:
In the presence of water, the hydrophobic tails tend to interact with each other, creating a hydrophobic space from which water is excluded and in which other hydrophobic molecules can be trapped, while the polar head interacts with water, and is solvated, preserving the hydrophobic part from all contact with water. For a hydrogen bridge to form, a molecule that has hydrogen attached to an atom of high electronegativity and another molecule that has another electronegative atom with high electron density (that is, a negative partial charge) is required. Water molecules in the bulk of the body of water maintain multiple interactions with other molecules through an extensive network of hydrogen bridges, so for polar compounds to enter, it would be necessary to break many of these bonds.

Na + Cl2 --> NaCl if you were given 15 grams of sodium (with excess chlorine) and asked to determine the amount of NaCl that would be produced (in grams), how would you go about doing it. Be as specific as possible and include numerical values when necessary.
Answer:
The correct answer is - 38.15 gm of NaCl.
Explanation:
Write the balanced equation for this reaction of sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl):
2Na + Cl₂ —> 2NaCl
the mass of Na and the mass of NaCl :
Molar mass of Na = 23 g/mol
In the balanced equation = 2 × 23 = 46 g
Molar mass of NaCl = 23 + 35.5
= 58.5 g/mol
similarly in balanced equation = 2 × 58.5 = 117 g
From the balanced equation above,
46 g of Na reacted to produce 117 g of NaCl.
By converting it to 15 grams of Na.
Therefore,15 g of Na will react to produce = (15 × 117)/46 = 38.15 g of NaCl.
Thus, 38.15 g of Na

How does caffeine affect blood pressure?
Caffeine may cause a short, but dramatic increase in your blood pressure, even if you don't have high blood pressure. It's unclear what causes this spike in blood pressure. The blood pressure response to caffeine differs from person to person.
Some researchers believe that caffeine could block a hormone that helps keep your arteries widened. Others think that caffeine causes your adrenal glands to release more adrenaline, which causes your blood pressure to increase.

Solutions having osmotic pressures less than those of body fluids are called Group of answer choices hyposmotic. hyperosmotic. magnosmotic. neosmotic. isosmotic. PreviousNext
Answer:
hyposmotic
Explanation:
Body fluids are in contact with cells. Cells are surrounded by a semi-permeable membrane, through which can pass certain solutes. If the concentration inside the cells is different from the body fluids, the water molecules will move from the more concentrated compartment to the less concentrated one. This process is called osmosis.
If the body fluids are more concentrated than cells, the solution is called hypertonic (body fluids are hyperosmic). If the body fluids are less concentrated than the cells, the solution is called hypotonic (body fluids are hyposmotic).

Which toxin is of particular concern for the infected host if antibiotics are used resulting in mass pathogen lysis? Cholera toxin Tetanus toxin Botulinum toxin Endotoxin
Answer: Endotoxin
Explanation:
Antibiotics generally target the cell walls of bacteria with the aim to dissolve it so that the body's immune system can be better able to attack it. When the antibiotics target these cell walls, pathogen lysis occurs and ruptures the cell.
Endotoxins are located in those cell walls and once free, are a source of concern because they can cause an array of medical problems with inflammation being amongst the mildest.

The statement that there must be a preexisting cell in order for a new cell to form is known as cell
Answer:
cells duplicate so when there is no cell it cant make any
Explanation:
The statement that there must be a preexisting cell in order for a new cell to form is known as cell theory.
What is cell theory?The scientific idea that cells make up living organisms, that they are the fundamental structural and organizational unit of all species.
They all originate from previously existing cells is known as cell theory. It was first proposed in the middle of the nineteenth century.
Because cells are the building blocks of all life, cell theory is essential for our understanding of biology.
We can have single-celled organisms like yeasts and bacteria. All living things grow and develop on the basis of cell division, or the division of a cell from one to two to four.
A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes.
Thus, the statement "cell arises from pre-existing cells" comes from cell theory.

In this task, you’ll record the direction of a compass as it’s placed at different points around a magnet. The investigation will try to answer the question, Do two magnets create magnetic force fields that allow them to interact without touching?
Part D :
How might someone dispute the results of this investigation? How might you counter the argument?
Answer:
It could be argued that there is a separate force acting upon the investigation. Or that the room is invalidating the results for some reason. Or that an error was made in measurement.
There are a thousand and one ways to try to dispute an investigation like this. However, for every argument that can oppose it, a counterargument can easily be made.
For instance, controlling the variables invalidates about 90% of any possible claims to the contrary. The majority of arguments would stem from the fact that it is nearly impossible to completely prove something in fear of external factors. The solution? Control the external factors.
So, in conclusion, a person could dispute the results of the investigation by claiming that something invisible like magnetics could not possibly be proven to exist, because there are all sorts of things that could be influencing the investigation. The way to counter the argument would be to prove yourself that the environment is controlled, and that nothing could be influencing the investigation.
