How would you go about finding the volume of your body?
Answers
Answer:
To find volume, you need the equation for volume, “volume is equal to mass divided by density”. So, knowing two of our three variables, we have a mass of 70kg divided by a density of 985 kg/m^3 equal to our volume, or . 0711 cubic meters, and since 1 cubic meter = 1000 liters, around 71 liters.
Which of these is a drawback of mining? O
A. Ecosystem restoration can take decades.
B. The practice provides many jobs.
O
C. Humans can obtain many useful minerals.
O
D. Working aboveground increases safety for miners.
Answers
The drawback of mining is that ecosystem restoration can take decades, as in Option A, as mining involves removing large amounts of earth and rock that can cause damage to ecosystems and habitats.
What effect does mining have on the environment?
Mining can have serious negative effects on the earth, such as climate change that can release large amounts of greenhouse gases, air pollution as emissions from mining operations can contribute to air pollution, which can have negative impacts on human health, and habitat destruction for different animals and plants too.
Hence, the drawback of mining is that ecosystem restoration can take decades, as in Option A, as mining involves removing large amounts of earth and rock that can cause damage to ecosystems and habitats.

During the light-dependent reaction of photosynthesis, light energy is converted into which form of energy?
Answers
Chemical energy
During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.
2. How could one change in a DNA nucleotide alter the formation of the translated protein
Answers
Answer AND Explanation:
Proteins are formed from the translation of mRNA to amino acid. Each set of 3 nucleotides make up a codon that codes for a specific amino acid. Frameshift mutations can also impact the formation of the protein. A change in a nucleotide does not always change the amino acid or protein because some amino acids have more than one set of 3 nucleotides that code for them. Valine, for example, is coded for by GUU, GUC, GUA and GUG. A change in the last nucleotide wouldn't affect the amino acid formed. However,GAG codes for glutamic acid.

Explanation:
The traits for blood type and Rh are the result of the presence or absence of particular (PROTEINS) or (ENZYMES) on the erythrocytes. Please choose the right answer in parenthesis :) <3
Answers
Answer:
The traits for blood type and Rh are the result of the presence or absence of proteins on the outside of erythrocytes, called surface antigens, being the antigens A and B, for the blood group, and the Rhesus factor for the Rh.
Explanation:
Blood group
The blood type or group is determined by the presence or absence of antigens A and B, which is determined by three genes A, B and O:
- Blood type A has antigens A, with a genotype A/A or A/O, which in turn is able to reject the presence of B antigen by producing anti-B antibodies.
- Type B blood has only B antigens, with possible genotype B/B or B/O. It can produce anti-A antibodies.
- The AB blood type has both antigens, with an A/B genotype, having both antigens do not react to the presence of an antigen.
- Blood type O is characterized by the absence of surface antigens, and its genotype is expressed as O/O.
Rh factor
The Rh factor, which owes its name to the rhesus monkey study, is also a surface protein - the Rh antigen - that determines this characteristic in the blood.
The nomenclature used for this type of blood uses the signs "+" or "-" after the Type ABO, indicating the presence or absence of the Rh factor, respectively.
- Rh+ blood has the Rh, D or Du antigen on the surface of the erythrocyte.
- The Rh- doesn't possess the antigen, and is able to make antibodies against the Rh antigen.
The importance of knowing the presence or absence of erythrocyte surface antigens is that it determines the compatibility of blood type, and the possibility of transfusions. The ORh- blood type is currently known to be a universal donor and AB+ is a recipient of any blood type.

the brown body colour of a drosophila fruit fly is dominant black body colour and is not sex linked explain how gregor mendel could have used a brown drosphilia fruit fly and a black drosphilia fruit fly to show that brown body colour is dominant to black body colour
Answers
Answer/Explanation:
Mendel could have crossed a true breeding (homozygous) brown fly with a true breeding (homozygous) black fly. BBx bb. The resulting offspring would all be Bb (heterozygous). If brown body color is dominant to black body color, all of these heterozygous flies would always be brown. This is because the brown allele is displayed over the black allele.

History of the Compound Microscope
Just as the Greeks had a fully functioning radiant heating system operating two thousand years before those only now being introduced in the US, so the origins of the compound light microscope appear to be traced, not to Holland, England or France - but to China which is perhaps appropriate given the present predominance of China in supplying compound light microscopes!

Answers
In a brightly lit room, the size of the pupil and lens become smaller.
•The pupils that are larger than normal are known as the dilated pupils.
•The size of the pupils is monitored by the tiny muscles in the iris, that is, the colored part of the eye and the amount of light reaching the eyes.
•In bright light, the pupils get smaller or constrict to inhibit too much light from invading the eyes. In dim lights, the pupils get larger or dilate to permit more light in.
•In bright light, the ciliary muscles contract and the radial muscles relax. This makes the lens to change its shape, it becomes smaller.
Thus, the size of the pupil and the shape of the lens become smaller in bright light.
