I’m pretty sure the answers are a. & c. Sorry if I’m wrong
A compound microscope has an application in colleges and schools. It exhibits two lenses, the ocular lens, and the objective lens. The compound microscope generally possesses more than one magnification power, varying from 40 times up to 400 or even 1000 times the original size of the specimen.
It is also used to observe tissue samples, micro-organisms, blood, microscopic cells, and some of the bigger details inside the cells. A transmission electron microscope exhibits the similar basic guidelines as the light microscope, however, the microscope rather than using light, it utilizes electrons.
These microscopes utilize electrons as a source of light. Due to the formation of low wavelength, it is feasible to obtain a resolution better than with a light microscope.
Answer:
Phenotypes of offsprings: Type A, Type B
Explanation:
This question involves a single gene for blood group in humans. The ABO blood group system consist of three alleles: A, B, and O. A and B are dominant over O but co-dominant to one another.
If a woman with type O blood (OO) has a child with a male with type AB blood (AB) i.e OO × AB, the following gametes will be produced by each parent:
OO - O
AB - A and B
Using these gametes in a punnet square (see attached image), the offsprings with the following genotyoes will be produced: AO (2), BO (2)
AO - phenotypically type A
BO - phenotypically type B
Hence, a type A and type B blood group offsprings will be produced.
Answer:
Answer: If you compare them, Denver has a much colder climate

Explanation:
Answer:
The correct answer would be d chloroplasts, which can be found in leaf cells of trees.
Chloroplasts are double-membrane cell organelle usually present in leaf cells of a plant.
They are the site of photosynthesis in plants by which plants convert solar energy into sugars. Oxygen is released as the byproduct of the process.
Light reaction of the photosynthesis takes place in the thylakoid membrane. It produces ATP and NADPH and releases oxygen.
Dark reaction takes place in the stroma of the chloroplast in which ATP and NADPH are used to fix carbon (obtained from carbon dioxide) into sugars (glucose).
The overall reaction is:
6CO₂ + 6H₂O + solar energy → C₆H₁₂O₆ + 6O₂
