There is 50 chance because there are two chromosomes that are same and two which are difeerent . XX MEANs girl XY means boys .
➜ The sex of an infant is determined by the type of sex chromosome contributed by the male gamete. Since the ratio of male gametes containing X chromosome and those containing Y chromosome is 50:50, the statistical probability of male or a female infant is also 50:50.

A container holds an element and a compound that are not chemically combined. Is this an element, a mixture or a compound?
Answer:
Mixture.
Explanation:
Mixture can be defined as a combination of two or more substances which are present in varied proportion and can be visibly seen by with our naked eyes.
In Science, there are two (2) main types of mixture and these are;
I. A homogeneous mixture: it can be defined as any liquid, solid or gaseous mixture which has an identical or uniform composition and properties throughout any given sample of the mixture. In Chemistry, all solutions are considered to be a homogeneous mixture. For example, aqueous hydrogen chloride is a homogeneous mixture of water and hydrogen chloride.
This ultimately implies that, in a homogeneous mixture, the different parts are uniformly (evenly) distributed.
II. A heterogenous mixture: it can be defined as any mixture which has a different or non-uniform composition and properties throughout any given sample of the mixture. This ultimately implies that, the constituents of a heterogenous mixture always remain separate in the sample and as such comprises of two or more phases.
For example, a mixture of sand and coffee is simply a heterogenous mixture and can easily be separated into their various components.
In this scenario, a container holds an element and a compound that are not chemically combined. Thus, this is a mixture.

I NEED THIS FOR NOW
I WILL GIVE YOU BRAINLIEST
Answer:
1) As soon as the paper cuts into the cells of your skin, your body springs into action. First, blood cells called platelets join together at the paper cut and form a clot to stop the bleeding.
The process is called Blood clotting.
2) The cell that are made will have the same same amount of DNA/chromosomes.
3) Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.

In an experiment, 90 newborn flies are divided evenly into three separate
groups and placed in boxes inside an incubator that is maintained at a
constant temperature of 30°C. On a daily basis, the first group is given water
containing 1 mg/mL of sugar; the second is given water containing 2 mg/mL
of sugar; and the third is given water containing 3 mg/mL of sugar. After four
weeks, the average length of the flies in each group is determined.
Which factor is the independent variable in this experiment?
A. Number of flies in a group
B. Average length of flies in a group
C. Concentration of sugar in the water
D. Temperature of the incubator
Answer: Average length of flies in a group is the right answer, I did it.
Even though mutations are relatively rare, they are still a concern in bacteria populations. Why?
Answer:
Mutations can provide resistance to antibiotics If we were to treat the bacterial population with that specific antibiotic, only the resistant bacteria will be able to multiply; the antibiotic selects for them. These bacteria can now increase in numbers and the end result is a population of mainly resistant bacteria.
Explanation:
Even though mutation is rare in bacteria, it is still important to be concerned about bacteria. The reason is that if any mutation happens that converts the bacteria into antibiotic-resistant bacteria, then this would be harmful.
What is mutation?Mutation is a phenomenon in which a change is seen in an organism's genome. It may be induced by chemical factors, environmental factors, etc. The mutation may be positive or negative.
In a population, evolution is seen due to mutation. It is one of the factors behind evolution. In bacteria, the mutation happens too. If any sort of mutation happens that makes them antibiotic-resistant, then it would be harmful for humans. Humans take antibiotics that destroy harmful bacteria. If these bacteria mutate their genetic constitution and become resistant, a higher dose of antibiotic will be required next time to destroy such harmful bacteria.
Hence, mutations in bacteria are harmful even though they are rare.
