Answer:
0.0025micrometer.
Explanation:
To calculate the actual size of the image, the formula to be used is
Actual size=Image size÷magnification.
The image size is 0.00005 wide
Magnification is 2000
First, convert the image size to micrometer.
=0.00005 × 1000000
50micrometers.
Actual size= 50÷2000
Actual size = 0.0025
Answer:
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
Answer:
B. Hardness
Explanation:
Physical properties of a substance is defined as the properties which can be observed or measured without changing the composition of matter.
Physical properties include odor, appearance, color, texture, boiling point, melting point and many others.
Hardness is a physical property of a substance as it describes the resistance of substance to deformation and can be observed by simple touch or without changing the composition of matter.
While reactivity, toxicity and flammability are chemical properties of substances that change one type of matter into another type.
Hence, the correct option is B.
The correct answer is - physically dettering herbivory, protection from frost, and minimizing evaporation.
The plants have developed multiple traits that help them in multiple different circumstances, and some of those traits are the thorns and the hairs on their steams and leaves.
The thorns primarily serve for protection of the plant. They are very sharp and give a painful sting (occasionally poisonous one), so they are a physical protection from the herbivores that would try to eat parts of the plants.
The hairs have multiple functions. They are like a coat that helps the plant to not be affected by frost, help to stop the evaporation, and also partially manage to stop most of the insects that feed on plants.
Genotypes: XX(75%), XhX(25%)
Phenotypes: normal
Their daughters won't get it because they would need to be homozygous for it and since the father is normal, it's not possible for them to inherit this from each parents and be homozygous (draw out a punnet square if ur confused). Hope this helps'
