Answer: 1200
Explanation:
If it was 1250 J of work done, and a object that weights 50 N, you subtract 50 from 1250 which is 1200 J. Work has been done, so you subtract the high number from the lowest.
Chromosomal mutations are changes in the normal structure or number of chromosomes. Changes in chromosome structure can result from errors in meiosis or from exposure to radiation or other damaging agents. Certain changes in chromosome number can result from nondisjunction during either meiosis or mitosis. Both structural mutations and nondisjunction can play a role in trisomy 21, commonly known as Down syndrome.
Answer:
Yes.
Explanation:
Yes, both structural mutations and nondisjunction can play an important role in trisomy 21 which also called down syndrome. In this type of syndrome, extra copy of chromosomes is present in the cell. Down syndrome is a genetic disorder that causes various defects in the children such as learning problems, facial features, vision and hearing problems.

What is the function of cell membrane
Explanation:
The function of the cell membrane is to protect the organelles that break down proteins and nutrients.
It is semi-permeable which means it takes in select nutrients and excretes cell waste into the bloodstream.
Species can change over time and adapt to their environment.
A. True
B. False
Answer:
True
Explanation:
This statement is true. A species can always change over time and adapt to their environment.
What are species?A species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. It is a class of plants or animals whose members have the same main characteristics and are able to breed with each other.
Moreover, it is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behavior or ecological niche.
Hence, species can change over time and adapt the conditions according to their environment.

Which of the following is not a step of Natural Selection?
Overpopulation
Survival of the Fittest
Underpopulation
Variation
Answer:
im pretty sure it is underpopulation.
Answer:
I think it's B. survival of the fittest since it's mostly just a phrase people say. I don't think underpopulation because, I'm pretty sure that's used when there not enough of an animal in an area, so while it could be the answer I don't think it is. And overpopulation is used when there's to much of an animal in an area so like with underpopulation it could be the answer but I do not think it is. And Variation is a step in Natural Selection so that's definitly not it. So since Survival of the fittest is mostly just a phrase people say I think that's the answer. Sorry for wasting your time if I'm wrong.

Explanation:
A protein isolated from a thermophilic bacterium shows a molecular weight of 160 kD when eluted from a size-exclusion chromatography column, but when the purified protein is run on an SDS-PAGE gel, a single band of 80 kD is observed. These results tell us that the protein is eluting from the size-exclusion column as a
Answer:
as a dimer consisting of two identical monomers (80 kDa subunits) that are packed together via hydrophobic interactions
Explanation:
SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is an electrophoretic methodology used to separate proteins that have a molecular weight between 5 to 250 kDa. SDS is a well-known ionic detergent that is able to break hydrophobic interactions and hydrogen bonds. Moreover, size-exclusion chromatography is a filtration technique that separates molecules in solution according to their molecular size. In this case, SDS-PAGE showed that the target protein is composed of two identical subunits (monomers) of 80 kDa each, which were separated by the detergent and formed one single band in the SDS-PAGE gel.

Answer:
D.
Explanation: Which pieces of information does the National Weather Service produce?
simple maps
newspaper maps
long-range forecasts
maps with isotherms
The National Weather Service produces long-range forecasts and maps with isotherms, but not simple maps or newspaper maps.
What is long- range forecast?Long-range forecasts are predictions of weather conditions that are expected to occur over a period of several days or weeks. These forecasts are typically based on computer models that analyze current weather data and historical weather patterns.
Isotherms are lines on a map that connect points with the same temperature. They are commonly used to show temperature patterns across a geographic region, and can be useful for understanding weather conditions and climate trends.
While the National Weather Service may produce maps, they are typically not simple maps or newspaper maps, as their focus is on providing accurate and detailed weather information to the public and other stakeholders.
