Ramer wants to find out how pressure affects the force of gravity acting on dust particles in a cloud. Ramer designs an experime

nt in which he places dust particles in a pressure chamber. He is able to adjust the pressure in the chamber from 0 Pascals to 780 Pascals. What should Ramer use as his control group?

Answer:

A vaccum should be used for the control group chamber.

Explanation:

In an experiment, a control is an experiment or observation designed to minimize the effects of variables other than the independent variable. The introduction of a control increases the reliability of the results; often through a comparison between the control measurements and the other measurements.

A vaccum according to this experiment is a chamber that will have no pressure within it. This will give a benchmark of the effect of pressure in this experiment.

Alfred Kinsey conducted research to determine what percentage of the population was heterosexual and what percentage was homosex
kow [346]

Answer:

B. He believed that sexuality is a continuum and wanted to classify people more precisely

Explanation:

Kinsey quantified in his studies heterosexuality and homosexuality on a continuous scale from 0 to 6, specified in heterosexual and homosexual experience and reactivity in each story. 0 on this scale is assigned to individuals with exclusively heterosexual sexual contacts and experiences and 6 to exclusively homosexual individuals.

He proposed a model according to which there are many intermediate degrees between heterosexuality and homosexuality. This gradualness was embodied in what is now known as the Kinsey scale.

the diploid number of chromosomes in horses is 64. what is the haploid number of chromosomes in horses?
OlgaM077 [116]
The haploid number of the chromosomes should be 32. 

Diploid number means that they have the complete sets of chromosomes in their cells, these cells are usually found in somatic (body) cells and different organisms have a different number. For example, a human somatic cell has 46 chromosomes, such as a muscle cell, or a skin cell etc. 

Meanwhile, haploid number means that the number of chromosomes in the cell only have half of the chromosome number than that of the diploid cells. These haploid cells are usually found in gametes of sexually reproducing organisms, such as human, we have 23 chromosomes in our sex cells. This is important because we have to make sure the chromosome number of offsprings are not doubled, as during sexual reproduction, male and female gametes fuse together to form a zygote. 

Therefore, to calculate the haploid number of a cell, we can divide the diploid number by 2, which is 64/2, and the answer would be 32.
