Which level of organization do all of the living and non living factors x interacting in the pond environment represent. Ecosystem, population, an organism, or a community?
Answer:
Ecosystem
Explanation:
An ecosystem is a level of organization referring to the group of living organisms including plants, animals, microbes interacting with one another, and also with the non-living parts of their environment e.g temperature, water.
Based on this explanation, a level of organization that encompasses all th living and non living factors interacting in the pond environment represent an ECOSYSTEM.

Which statement is false about B-lactam antibiotics?
a) They are inactivated by bacterial B-lactamases
b) They can maintain their activity by co-administering B-lactamase inhibitors
c) They are reversible inhibitors
d) They inhibit a bacterial transpeptidase reaction
Answer: c) They are reversible inhibitors
Explanation: B-lactam antibiotics are not are reversible inhibitors. reversible inhibitors are inhibitors which the allow enzymes they inhibit to start working again, as there is no perman effects on the enzymes ( there is no change to the shape of it active site.). They can sometimes appear as competitive, non-competitive or uncompetitive.

This is a molecule of glucose, a simple carbohydrate. If this molecule were broken down, would it provide all of the elements needed to assemble lipids, nucleic acids, or proteins? Use evidence from the diagram in your answer.
Answer:
The correct answer is - no.
Explanation:
Carbohydrates are made up of thee elements carbon, hydrogen, and oxygen so if the carbohydrate is completely broken down it will release these elements.
Lipids are made up of similar elements as glucose however, they also contain sulfur and phosphorus. Similarly for proteins and nucleic acid nitrogen, nitrogen sulfur, and selenium other than the elements released by glucose.
Thus, the correct answer would be - no.

Certain unusual aspects of brain structure were observed in the brain of Albert Einstein. One interpretation is that he was born with certain differences in his cortex from others that encouraged his scientific and intellectual abilities. What do you think of this explanation and what do you think could be an alternative interpretation
Answer:
It seems a plausible inference. An alternative hypothesis is one in which this anatomical difference is present in low population frequency, thereby further scientific observations are needed to confirm (or reject) this hypothesis
Explanation:
Albert Einstein's brain exhibited an unusual anatomical conformation in the prefrontal cortex. Intriguingly, this brain area is involved in abstract thinking, thereby it has been suggested that the amazing cognitive capacities of Einstein may be due to his prefrontal cortex. A way to test this hypothesis is by an observational study with the aim at determining if this feature is exclusive of Einstein's brain.
How many bacteria will there be after four hours from a single bacterium that divides to produce two cells every 15 minutes
Answer:
65,536 cells
Explanation:
According to the question, a single bacterium will divide into new cells every 15minutes. Since there are four 15 minutes in one hour, which is 60 minutes, a single bacterium will have divided (4×60/15) times =
= 240/15
= 16 times.
Since a single bacterium will divide 16 times in four hours cells, then in four hours, a single bacterium will have divided into 2^16 = 65536 new cells.
Note that, the number of cells a bacterium cell that will divide in two can be expressed as 2^n where n is the number of times
If a bacterium divides into 2 every 15 minutes, there would be 65536 bacteria after four hours.
The bacterium divides into 2 every 15 minutes. Thus, the cell will divide:
60/15 x 4 = 16 times in 4 hours
Thus:
First division = 2 cellsSecond division = 4 cellsThird division = 8 cellsFourth = 16 cellsFifth = 32 cellsSixth = 64Seventh = 128Eighth = 256Ninth = 512Tenth = 1024Eleventh = 2048Twelfth = 4096Thirteenth = 8192Fourteenth = 16384Fifteenth = 32768Sixteenth = 65536More on bacterial division can be found here: https://brainly.com/question/621474
what do you think the difference between simple and complex carbohydrates is?
Answer:
Complex carbohydrates are present in foods such as bread and pasta. Simple carbohydrates are in foods such as table sugar and syrups. Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy.

The blood-brain barrier (BBB) is most permeable to which of the following?
A. Platelets, white blood cells and red blood cells.
B. Sodium, potassium and chloride.
C. Glucose and oxygen.
D. Antibiotics.
Answer:
C. Glucose and oxygen.
Explanation:
The blood-brain barrier is a composition of endothelial cells that regulate the entry of substances into the extracellular fluid found in the central nervous system. Their high degree of selective permeability ensures that no solutes can cross the barrier, and only the right substances which are crucial to the workings of the central nervous system can scale through.
Oxygen which is needed for the proper functioning of the central nervous system and which is hydrophobic in nature is allowed to pass the blood-brain barrier. Glucose too which is an important nutrient/macromolecule for brain health can also move through the blood-brain barrier.

A cell membrane is very specific about what it allows across. How does t help the cell?
Answer:
Explanation:
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled

Question 5
If you removed the lens from an eye and looked through it at an upright tree, how would the tree appear?
upright
upside down
the top of the tree would be pointing to the left
the top of the tree would be pointing to the right
If you removed the lens from an eye and looked through it at an upright tree, the tree appear upside down. Thus, the correct option for this question is B.
What is the function of the lens?The function of the lens in the eyes is to focus light rays onto the retina. Then the retina converts this light into electrical signals which send messages to your brain and creates the image that you observe.
The lens of the eye is the translucent biconvex structure that dangled behind the Iris of the eye. If you eliminate the lens from an eye and looked through it at an upright tree, then the perception of light is not made and cannot stimulate electrical signals by the retina, and the tree will appear upside down or an inverted image is formed.
Therefore, the tree will appear upside down, if you removed the lens from an eye and looked through it at an upright tree. Thus, the correct option for this question is B.
