A blood group refers to the classification of blood based on the presence of the sugars or proteins on the membranes of red blood cells called the antigens and the proteins in the blood plasma called the antibodies. Karl Landsteiner in the year 1901, classified the blood groups into the four groups A, B, AB and O which is called the ABO system of blood grouping.

If a classmate tells that a person can have type AO blood, we cannot agree. There are only four blood groups A, B, AB and O and they can be either negative or positive based on the absence or presence of the Rhesus antigen. A person with blood group A can have the allele (alternative forms of genes) A with the genotype AA or AO. Hence AO is not a blood group and it can be one of the genotype of blood group A.

No, the only blood types possible are A, B, AB, and O. also + or - for each.

The mechanism for reactive oxygen species to cause mutation is Select one: a. bases are oxidized to a variety of different produ

nevsk [136]

Answer:

Option a. is correct

Explanation:

A mutation refers to a change in our DNA sequence which causes it to break down. It occurs due to the following reasons:

1. Due to mistakes when the DNA is copied

2. Due to environmental factors such as UV light, smoking.

3. Exposure to specific chemicals or radiation

The mechanism for reactive oxygen species to cause mutation is that bases are oxidized to a variety of different products which might pair with a different base than the original base would have.

Humans get D vitamin from sunlight. the plants perform photosynthesis and grow , we eat those fruits and vegetables grown in the plants. so indirectly we humans and other animals are benifitted from sun sunlight . flesh eating animals eat herbivores animala so they are also benifitted

1. The effect of initial population sizes on the growth of populations of an organism was

ella [17]

When graphing data, we must consider the variables, label axes, define units of measure. In this case, variables are initial population size / final population size, showing an directly proportional relationship.

-------------------------------------

We need to construct a graph illustrating the data in the table.

We can make a dispersion graph. To do it, we need to define variables.

Since we want to know how different initial population sizes affect population growth,

the independent variable is the initial population size
the dependent variable is the final population size (after 24 hours)

The final population size depends on the initial population size. This is, the number of individuals at the beginning will influence the final number of individuals.

Initial population sizes ⇒X horizontal ax ⇒Unit: Number of individuals
Final population sizes ⇒ Y vertical ax ⇒ Unit: Number of individuals

By making a dispersion graph, we can represent the effect of the varying initial population sizes on the final population sizes. We can compare these effects and observe how populations grow as the N₀ increases.

We can also choose a bar graph. In this way, we can compare initial and final population sizes.

This graph will show populations and two bars per population.

Blue bar ⇒N₀⇒ Initial population size
Red bar ⇒N₁ ⇒ Final population size

Different populations ⇒ 1, 2, 3, 4, 5 ⇒ Represented in the X horizontal ax

The number of individuals ⇒ from 1 to 324 ⇒ Represented in the Y vertical ax.

By making a bar graph, we can represent initial and final population sizes and compare them. The population that begins with 1 individual, after 24 hours has 4 individuals. The population that begins with 3 individuals, ends with 9 individuals. And so on.

No matter which graph you choose, you will observe a directly proportional relationship between both variables. The bigger is the initial population size, the bigger it ends after 24 hs.
