no mitochondria; anaerobically
mitochondria; aerobically
no mitochondria; aerobically
None of the above
Answer:
no mitochondria; anaerobically
Explanation:
Red blood cells have no mitochondria and generate energy anaerobic. So, the answer would be B. You can easily eliminate A. and C. because they mention that blood cells have a mitochondria, but they don’t.
according to the hydrologic cycle, once precipitation has fallen on land, what paths might the water directly take?
Answer:
it either soaks into the ground, infiltration, flows over the surface as runoff, or immediately evaporates.
why did the early atmosphere not have much oxygen?
Answer:
The oxygen did not build up in the atmosphere for a long time, since it was absorbed by rocks that could be easily oxidized (rusted). To this day, most of the oxygen produced over time is locked up in the ancient "banded rock" and "red bed" rock formations found in ancient sedimentary rock.

how will you select and grow a resistant strain of e. coli in this experiment?
Streptomycin treatment is used in medicine. It s growth is to expose a sample of E.coli to streptomycin by innoculating it into a streptomycin positive plate. any colonies that grow will carry a mutation for resistance.
Streptomycin treatment is known to boast or increase the growth of E. coli by nitrate respiration.Streptomycin is simply regarded as an antibiotic which is often used to treat moderate to severe tuberculosis, pneumonia, E. coli, etc.
See full question below
How will you select and grow a resistant strain of E.coli in this experiment?multiple choice:
(1). expose a sample of E.coli to streptomycin by innoculating it into a streptomycin positive plate. any colonies that grow will carry a mutation for resistance,
(2.) expose a sample of E.coli to sterptomycin by innoculating it into a streptomycin negative plate, any colonies that grow will carry a mutation for resistance,
(3.) samples of bacteria are taken from the culture and observed under a microscope for signs of susceptibility or resistance. those that are resistant are separated and plated.
(4.) a culture of E.coli will be mixed with streptomycin so that the antibiotic can alter the genetic composition of the bacteria

Life on earth is incredibly diverse. Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms. Life on earth is incredibly diverse. Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms; the genes they contain; and the ecosystems they form on land and in water. Biological diversity is constantly changing. The source of this diversity is evolution, the process of gradual change during which new species arise from older species. Evolutionary biologists study the evolution of living things in everything from the microscopic world to ecosystems. There are so much duversity in life on the Earth because there are great numbers of species on the earth, the present day organism are the end product of about 3.5 billion years of organic evolution on earth.

Which Organelle assembles amino acids to create proteins?
A. Ribosome
B. Lysosome
C. Chrolorplast
D. Cell membrane
The answer should be A - Ribosome because during protein synthesis, ribosomes assemble amino acids into proteins and ribosome’s are the cellular structures responsible for protein synthesis.
hope this helps!
Ribosomes assembles amino acids to create proteins. The correct option A.
Ribosomes are the organelles responsible for assembling amino acids to create proteins in cells. Ribosomes are composed of RNA and proteins, and they exist either freely in the cytoplasm or attached to the endoplasmic reticulum (ER).
During protein synthesis, the ribosomes read the genetic information encoded in mRNA (messenger RNA) and facilitate the process of translation. Transfer RNA (tRNA) molecules transport amino acids to the ribosomes, where they are joined together in the correct sequence to form a protein chain.
Thus, the ideal selection is option A.

The thin, protective mucous membrane composed of nonkeratinized stratified squamous epithelium with numerous goblet cells that is supported by areolar connective tissue is known
The conjunctiva is a thin transparent mucous epithelial membrane that lines the inner surface of the eyelids made up of goblet cells whose function is to protect the eyeball.
The conjunctiva is an almost transparent membrane that covers the white part of the eye, the sclera, and also the eyelids on the inside.
Its function is to protect the eyeball from external agents, although it also intervenes in the formation of tear components and in the immune defense of the eye.The conjunctival epithelium is a non-keratinized squamous stratified epithelium like the corneal epithelium but contains mucin-secreting goblet cells that maintain the tear layer.Therefore, we can conclude that the conjunctiva is a mucous membrane that is formed by non-keratinized squamous epithelium whose function is protective and lubricant.

Answer:
more active transport occurs in cell A then cell B
Explanation:
hope this helps ;)
The possible conclusion that can be made drawn about the activity of these two cells is that more active transport occurs in cell A than in cell B. The correct option is B.
What is transport?Active transport is a type of transport that cells use to move molecules up and down cell membrane concentration gradients.
Moving actively is carried out using a variety of membrane proteins known as carrier proteins that are connected to an energy source, such as ATP, for example.
The energy needed to move molecules or ions up or down a concentration gradient is provided by the hydrolysis of ATP during this process, known as active transport. The other transport is passive transport, which is reverse.
Therefore, the correct option is B. more active transport occurs in cell A than in cell B.
