Cell biologists studying the mobility of plasma membrane proteins fused mouse and human cells together, creating a heterokaryon. They then examined the localization of mouse and human proteins over time. Initially the mouse and human proteins were restricted to separate halves of the heterokaryon. Over time the mouse and human proteins mixed, with each protein eventually being present over the entire cell surface, consistent with proteins being able to move within the plane of the membrane. What techniques could have been used to examine the locations of the mouse and human membrane proteins
Answer: Fluorescence microscopy
Explanation:
A protein is substance that is the essential constituent of living cells because it forms part of its structure. They are also found in plasma membrane, where they assist substances to cross the membrane. Proteins can be:
Integral: permanently attached within the plasma membrane.Transmembrane: it spans the entirety of the cell membrane.Peripheral: are only temporarily associated to the membrane.Some integral proteins can act as cellular receptors. Other proteins are responsible for cell adhesion (binding of a cell to another cell or to a surface). On the outside of the cell membranes, attached to other proteins, are the carbohydrate chains that act as labels identifying the type of cell.
A heterokaryon is a multinucleate cell and in this experiment the scientists fuse a human cell and a mouse cell, each of them will have their own proteins. At first, the human and mouse proteins where found in separated halves of this heterokaryon. But after a while, those proteins where mixed and could no longer be identified.
A fluorescent chemical called a fluorophore is able to be absorb light of specific wavelengths and then emit light of longer wavelengths. The proteins can be modified and marked with different colored fluorophores to detect them, even if they are mixed in the heterokaryon. Then, they can be seen with a Fluorescence microscopy, to identify them through different colors.

PLEASE HELP!!!? Are humans an invasive species? Why or why not. GIVE TWO PIECES OF EVIDENCE TO SUPPORT YOUR OPINION.
Answer:
I think yes, humans are an invasive species.
Explantation:
I think humans are an invasive species because they are everywhere, and very few places in the world do not have humans. Humans are in control of the planet because of their number. Humans are not going to be extinct ever. They are always going to be here on earth. If somebody finds new land, they make a base/camp and send other people to live there and to populate it. Like in North america, settlers came and sent men to live there. They hunted animals and set up homes. Then, more and more people came and soon all that is left is a over populated land with citys and cars and humans everywhere.
I hope this helps. :)

Animals, plants, fungi, protists, and archaebacteria and eubacteria are the 6 kingdoms of living things.
Bacterial Kingdoms and Archaean Kingdoms: These are prokaryotic ones and not posses a well developed nucleus. Example bacteria.Protists: These are eukaryotic which can be unicellular or multicellular. Example: amoebaFungi: These are also eukaryotic having single or many cells including yeast. They are not capable of photosynthesis.Plantae: These are photosynthetic eukaryotes which are primary producers. Example all plants.Animalia: these are heterotrophic eukaryotes which include all animals.Thus, these are the six kingdoms including their characteristics.

There are five different types of nucleotide bases found in living things. Which
is an accurate comparison of the bases found in robins and the bases found
in sparrows?
A. Sparrows have only one type of base in their cells; robins have
many
B. Robins and sparrows have different types of bases.
C. Robins and sparrows have different arrangements of the bases.
D. Robins and sparrows have the same arrangement of the bases.
Answer: the answer is C —> AP.EX
Explanation:
The nucleotide bases are the nitrogenous rings that form the backbone of the nucleic acid. Robins and sparrows have the same bases with different arrangements. Thus, option C is correct.
What are nucleotide bases?The nucleotide bases or the nucleobases are the fundamental units that together with the sugar molecule and phosphate make the structure of the DNA or RNA.
There is a total of five nucleotide bases divided into purines and pyrimidines based on their ring structures. The purine consists of adenine and guanine, pyrimidine of cytosine, uracil, and thymine.
The bases are universal in organism containing the DNA or RNA but only differs in their arrangements that result in the development of the various traits and characteristics of the organism.
Therefore, in option C. the bases are arranged differently in species.

Liquid water evaporates or the process of transpiration, forming water vapour that moves through the atmosphere, then comes down as precipitation, either enters the soil or transfers onto the lakes, rivers, oceans, etc.
What is water cycle?The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
Moreover, the water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
Therefore, the hydrologic cycle is important because it is how water reaches plants, animals and us! Besides providing people, animals and plants with water, it also moves things like nutrients, pathogens and sediment in and out of aquatic ecosystems.

The IQ range that indicates moderate mental *********** is A. 70-79.
What is an IQ?
IQ stands for Intelligence Quotient and is a measure of cognitive abilities and intellectual potential. It is determined through standardized tests that assess various cognitive skills, including problem-solving, memory, and analytical thinking.
The average IQ score is set at 100, with scores ranging from 70 to 130 considered to be within the normal range. Scores below 70 indicate varying degrees of intellectual disability, while scores above 130 suggest above-average intelligence.
While IQ scores can provide insight into a person's cognitive abilities, they do not account for other factors, such as emotional intelligence or creativity, that may contribute to overall success in life. It is essential to recognize that IQ tests have limitations and should not be used to label individuals or limit their potential.
This range is considered to be a mild to moderate intellectual disability, indicating limitations in adaptive functioning and potential need for support in daily life activities.
