Answer:

2.956 × 10 ⁻¹¹ g

Explanation:

The mean concentration of hemoglobin in red blood cell = 0.34 g/ml

average volume of a red blood cell = 87μ m³ where 1 μ m³ = 1 × 10 ⁻¹² ml

average volume = 87 × 1 × 10 ⁻¹² ml  = 87 × 10 ⁻¹² ml

weight of hemoglobin contained in an average red blood cell =  87 × 10 ⁻¹² ml × 0.34 g/ml = 2.956 × 10 ⁻¹¹ g

Which type of cell is responsible for causing apoptosis in cancer cells and virus-infected cells?
lbvjy [14]
The answer is natural killer cells.

Natural killer cells are a type of lymphocytes and they are important for the innate immune system. They recognise stressed cells much faster than other immune cells. Their response is rapid and usually only a few days after a viral infection. They also respond to <span>cancer cell </span>formation. While other immune cells can detect only those harmful cells that have specific markers on the surface of the cell membrane, natural killer cells can even detect those cells that miss markers for apoptosis.

Based on the information in the table, which of the following changes is least likely to produce a phenotypic
yaroslaw [1]

GAU to GAC​ is least likely to change phenotype of an organism.

<h3><u>Explanation</u>:</h3>

Phenotype of an organism is defined as the physical characteristics of an organism. This phenotype is dependent on the genotype of the organisms. This means the phenotypic characters are actually the expressions of the genes of the organisms. Now the genes are expressed in form of codons that are the three nitrogen base sequences. Each codon codes for a particular amino acid which in turn polymerises to from the protein which actually forms the phenotype of the organism.

Now there are 20 amino acids and 64 codons. Thus there are more than 1 codons for a single amino acid. So, if a codon is replaced by another codon which codes for same amino acid, then the phenotype is least likely to be affected.

Both the GAU and  GAC​ codes for aspartic acid. So the phenotype won't be affected much by this mutation

name two medical technologies that have helped combat the spread of disease in cities. Explain how each technology has helped
ivanzaharov [21]

Answer:

Masks and Vaccines (RNA vaccines but normal vaccines help as well)

Explanation:

Masks: As we can tell cities that have a mask mandate have lower corona numbers

Vaccines: Vaccines give your body the antibodies that it needs to protect your body from infection without the virus. RNA vaccines are better than the normal vaccines because they are going to be produced faster than normal vaccines
