Answer:
O: Type O individuals can donate blood to anyone, because their blood has no antigens. However, they can only receive blood from other type O individuals (because blood with any antigens is seen as foreign).
This dichotomous key helps scientists classify within the arthropoda phylum. If scientists discover an organism with: less than 10 legs, 6 legs, wings, wings with 1 or 2 colors, with legs that are approximately the same length, wings that are not net-like, and wings that meet in a straight line down the back, how would this organism be classified?
You'll have to follow the dichotomous key that's provided to you. Start by choosing less than 10 legs, then choose 6 legs, then with wings, then wings with 1 or 2 colors... etc. You should end up identifying an organism this way.. following the path.
what measures to be taken in an operating room
Answer:
infection control- clean equipment to prevent spread of germs
All items needed for the operation should be in place and an adequate supply of regularly used items should be on hand to minimise movement to and from theatre during the operation
Everything needs to be sterile
All instruments need to be inspected for any signs of contamination after the sterilisation process
Shoes from outside should never be worn inside an operating room
Theatre hats are worn routinely, and prevent loose hair and skin from falling on wounds or equipment
The surgical mask was introduced over a century ago. Its continued use is controversial as evidence is not conclusive that wearing a mask reduces postoperative infection. Wearing a mask, however, does protect the practitioner from contact with body fluids

The amount of energy available to do work will increase.
The ecosystem will move away from equilibrium.

Answer:
I think the entropy of the ecosystem will increase.
In a paragraph below, explain the definition of biotechnology and cite at least three examples of it. Also, explain why it is a controversial field of science.
Answer:
Biotechnology is a branch of science that deals with technology by utilizes biological systems, living organisms, or parts of this to develop or create products with the goal of human welfare.
During brewing and baking bread yeast are used to produce alcohol are examples of processes that fall within the concept of biotechnology, Genetically modified orgnisms and crops are also product of the biotechnology. The insulin production also an example of this process.
People consider use of biotechnology unethical to produce genetically modified organisms or crops and cloning is considered as against the law of nature.
How can students in the photograph use the net to sample the invertebrates in the river.
Answer and Explanation:
Macroinvertebrate communities show spatial and temporal variability. Many taxons have more affinity for one specific type of habitat.
There are two principal sampling techniques. Qualitative and cuantitave. Qualitative techniques provide data about the river richness and the relationship between the different taxonomic group's abundance. They allow the obtention of the most representative and abundant taxons, estimates their densities, biomass, and calculates the diversity indexes for each sampling site by period. Nets are needed to sample.
Every possible microhabitat must be sampled. The use of the different sampling elements depends on the substrate.
Hard-substrated sites, such as rocks or wood and organic matter, are sampled using a Surber net. The net is placed counter-current. The substrate must be moved and removed up to 10-15 cm deep, checking that animals and the thin sediment lie on the net. Samplings must be done from downstream to the upstream direction, taking replicates per substrate. Invertebrates must be washed on a strainer. Finally, place each of the samples in a plastic bottle, fixate the material with formaldehyde 4% and take it to the lab for its taxonomic identification.Kingdom protista contains organisms that do not fit into other Eukarya Kingdom. Explain 3 ways that protists are different from animals, plants and fungi.
Explanation:
Protists are eukaryotes, and most are single-celled. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.
protists is a paraphyletic name for unicellular Eukaryota organisms.
Explain the difference between prokaryotes and eukaryotes. Include which type of microorganisms are included in each domain
Answer:
eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead.

What causes surface tension in water?
which instrument would produce
sound with the longest wavelength?
a. Flute
b. Bass guitar
C. Violin
d. cymbal
Answer: Long wavelengths are the result of a deeper sound since it takes longer for it to travel through a medium. The Bass Guitar is your best bet as it is the lowest sounding instrument, meaning is had the longest wavelength.

Which is the best explaination for how chemical energy is transferred with cells
Answer:
Inside the cell, each sugar molecule is broken down through a complex series of chemical reactions. As chemical energy is released from the bonds in the monosaccharide, it is harnessed to synthesize high-energy adenosine triphosphate (ATP) molecules. ATP is the primary energy currency of all cells.

There are two bright stars in a constellation. One of the stars appears red and the other star appears blue. Which of the following is the best explanation for the difference in the stars' color?
The blue star must be moving toward Earth and the red star away from Earth.
The red star must be moving toward Earth and the blue star away from Earth.
The red star must have a greater surface temperature compared to the blue star.
The blue star must have a greater surface temperature compared to the red star.
Given what we know, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.
How do we explain this?This has to do with a phenomenon known as the doppler effect. This effect explains how we can perceive a star as red or blue depending on its distance and on whether or not it's moving towards or away from us. When an object moves away from us, the wavelengths of the light it emits are stretched, making the object appear red. However, when it moves towards us, this increases the wave frequency that reaches us and we observe it as blue.
Therefore, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.
