<span>The temperature in the laboratory
            The position of the Bunsen burner
            The amount of air that mixes with the gas stream 
these can all have an affect on the intensity of the reaction. 

I hope I was helpful.</span>

Well the amount of air matters so ... seeing as there is no answer choices im going to say that the amount of air that mixes with the gas will cause the intensity of the reaction to increase or decrease so with that said i hope this helps :)

Fisher was found lying on his back. Is it likely that his body was moved after death? Why or why not?
Tpy6a [65]

Answer:

Is it likely that his body was moved after death? The answer is NO

Why or why not?

This is due to postmortem staining seen on his back which would have been observed on other parts of the body if the body was moved after death

Explanation:

Livor mortis: is the stage where the heart stops pumping blood through the circulatory system causing blood accumulation at the lowest point of the body. It's also called postmortem stain.

It helps in judging the time of death for a body, the location and position of the body if it's at the spot.

Corn develops from a seedling with a single cotyledon, displays parallel veins on its leaves, and produces monosulcate pollen. I
Rzqust [24]

Answer:

a monocot

Explanation:

Monocotiledoneas are plants that develop from a seedling with a single cotyledon. That is why we can say that maize is a monocotyledon.

Monocotyledons and dicotyledons are two classes of vegetables that belong to the angiosperm plants (plants with seeds contained within the fruits) and also phanerogams (flowering plants), currently classified as magnoliophytes, gathering approximately 230 thousand species. Monocotyledons are plants that have only one cotyledon in the seed. Cotyledons are the initial leaves of plant embryos.

Which of the following conditions would increase the accuracy of a molecular clock?
Andru [333]

Answer: A. The genes encode resistance to antibiotics.

D. The genes are carried on plasmids

F. The "clock"genes are highly mobile between species.

Explanation:

Molecular clock is a tool that is used to calculate the time of the evolutionary events. These are the gene sequences that are used to determine the evolutionary distance between the new and primitive organisms developed on earth. It also measures the random changes just like mutation. Thus the molecular clock is also called as the gene clock or evolutionary clock.

The accuracy of the molecular clock can be increased by the genes that encode for a resistance against the antibiotics, the genes that are carried on the plasmids and the clock genes which are highly mobile among the species.

<u>Answer</u>:

The nucleus is primarily stores most of the cell's DNA.

<u>Explanation</u>:

It is made up of two chains which coils around each other, together they form a helical structure tat further carries the genetic information, which will help in the development, functioning and also the growth and reproduction in all known organism and in viruses. The nucleus is stored in it and the nucleus has the genetic material. They are composed of the nucleotides, in which each nucleotide has four nitrogen. These nucleotides are together joined with covalent bond to each other. Together they have the biological information.
