Explanation:
which do all cells need in order to function?
a: oxygen
b: water
c: carbon dioxide
d: offspring
Answers
Answer:
A. Oxygen ( for animals )
B and C ( for plants )
Explanation:
Cellular nutrients come in many forms, including sugars and fats. In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. During cellular respiration, oxygen is needed. Carbon dioxide is the product of cellular respiration.
In the event you are referring to plants, then both water and carbon dioxide are needed for photosynthesis.
Oxygen is required by all cells in order to function properly. Thus, the correct option is A.
What are Cells?Cells may be defined as the building blocks of living organisms. They are considered the basic structure and functional unit of life. All living beings are made up of cells.
Antony von Leeuwenhoek discovered the living cell for the very first time in 1674 with the help of an improved microscope in Pond water.
Cells require oxygen because they have the ability to break down food particles in the presence of oxygen to derive energy for metabolic activities. This process of breaking down food in the presence of oxygen is known as cellular respiration.
This is because oxygen functions as a final electron acceptor in the electron transport chain to synthesize an energy molecule known as ATP.
Therefore, Oxygen is required by all cells in order to function properly. Thus, the correct option is A.

What foods below would test positive for starch in the presence of iodine?
Question 8 options:
a steak
a hard boiled egg
noodles, bread, or crackers
chicken
Answers
The group of foods that would test positive for starch in the presence of iodine would be noodles, bread, or crackers.
Noodles, bread, or crackers consist largely of starch. Starch has the capacity to turn the brown color of iodine to blue-black because the iodine molecules insert themselves in the structure of the amylose content of the starch.
Foods like steaks, hard-boiled eggs, and chicken are essentially made of proteins and will, therefore, fail the iodine test for starch.

What is force?Force is defined as an outside force that has the potential to alter how a body is moving or resting. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. The idea of a force encompasses both living and non-living things. The body can change its size, shape, and direction when force is applied. As we discovered in a previous session, forces are significant because they induce modifications to motion.
Net force is defined as all of the forces pulling on a thing combined. The net force, which is a single force, replaces the original forces' influence on the particle's motion. The top 5 words that are similar to "net force" in terms of this word similarity engine are resultant force, force, acceleration, physics, and rotation.
Thus, the surface is the student not able to move the box is D.

A person filters 720 millimoles of K in a day and secretes 42 millimoles. She excretes 75 millimoles in her urine. How much is K is reabsorbed, in millimoles
Answers
Answer:
687millimoles
Explanation:
To calculate the amount of K reabsorbed in the kidney of an individual, we say:
Amount reabsorbed = Amount filtered + Amount secreted - Amount excreted
Based on the provided information,the respective amount of K is:
Amount filtered = 720 millimoles
Amount secreted = 42 millimoles
Amount excreted = 75 millimoles
Hence,
Amount reabsorbed = 720 + 42 - 75
Amount reabsorbed = 762 - 75
Amount of K reabsorbed = 687millimoles

closer to the Sun in the summer than in the winter
Student 2: I disagree. Although the distance between Earth and the Sun does change
throughout the year, I don't believe that the seasons and changes in Earth's surface temperature
are caused by the distance between the Sun and Earth. If the seasons were due to the Sun-Earth
distance, then both hemispheres of Earth would have the same seasons at the same time.
Do you agree or disagree with either or both of the students? Explain your reasoning.
Answers
Student 2 discussion is true as distance between Earth and the Sun remain same, if the seasons changes were due to the Sun-Earth distance, then both hemispheres of Earth would have the same seasons at the same time.
What is hemisphere ?A hemisphere refers to half of the earth surface, that is divided into northern hemisphere or the southern hemisphere, the cutting of the sphere into two equal halves with one having flat side.
Geometrically the hemisphere is a 3D shape it is half of the sphere is flat and the other side is a circular bowl and it is formed when a sphere is cut at the exact center having two equal hemispheres.
A hemisphere has a surface area which is curved, no edges and no vertices, not a polyhedron, but it has one circular base and one curved surface.
The diameter of a hemisphere is a line type of segment that passes through the center and touches the two opposite pole , the radius of a hemisphere is from the center to a point on the curved surface of the hemisphere.

You have been studying the lysosomal enzyme cathepsin D in mammalian cells. To look at the localization of the enzyme, you incorporate 32 P into the cells over a long period of time and collect fractions of the cell lysate corresponding to various organelles. Much to your surprise, you find cathepsin D was isolated in the ER fraction, and it contains 32 positive sugar side chains. However, when you pass this enzyme through an affinity chromatography column containing mannose-6-phosphate receptor conjugated to resin, the enzyme passes straight through. However, your cousin calls you up and tell you that she modified your cell line. She claims that she deleted your endogenous cathepsin D gene and transfected a plasmid containing a cathepsin D gene with a Lys-Asp-Glu-Leu (KDEL) sequence on the C-terminus.a) Why is the lysosomal enzyme found in the ER fraction rather than in the lysosomal fraction?b) Explain why the modified enzyme does not bind to the mannose-6-phosphate receptor.
Answers
Answer:
Explanation:
1.
Cathepsin is involved in programmed cell death, it is a lysosomal enzyme and the reason it is found in the ER fraction instead of the lysosomal fraction is because of its c terminal KDEL sequence. this sequence ia a retrieval for protein and causes a backward movement of protein back to endoplasmic reticulum. that is why cathepsin seems to have localised in ER instead of the lysosomal fraction
2 It does not bind to mannose-6-phosohate receptor because this glycosylation process does not occur in the E.R but in Golgi bodies. because of the KDEL sequence this glycosylation of cathepsin would not occur and cathepsin would go through affinity column without any form of binding to receptor.If cathepsin can get to the Golgi then glycolysation with Mannose6phospate can occur.
A series of two-point crosses were carried out among seven loci (a, b, c, d, e, f, and g), producing the following recombination frequencies. Map the seven loci, showing their linkage groups, the order of the loci in each linkage group, and distances between the loci of each linkage group.
