Dmitry_Shevchenko [17]

Answer:

See the answer below

Explanation:

It may seem that the question is incomplete. The complete question reads:

Match each statement to the type of behavior it describes. Jenna published the results of her latest experiment for the public to see. Malcolm altered an experiment to be able reach his desired conclusion. Elena keeps complete records of all her experiment results. Neal shared the results of his field study even though they didn’t support his hypothesis. <em>Put each description to the group it belongs to. 1.Responsible 2.Irresponsible.</em>

<em>To answer the question:</em>

<em>Responsible behavior</em>

  • <em>Jenna published the results of her latest experiment for the public to see.</em>
  • <em>Elena keeps complete records of all her experiment results.</em>
  • <em>Neal shared the results of his field study even though they didn't support his hypothesis.</em>

<em>Irresponsible behavior</em>

  • <em>Malcolm altered an experiment to be able to reach his desired conclusion</em>

Responsible behaviors are those that support responsible scientific practices and do not jeopardize the objective nature of research. Every data during experiments must be well kept and after thorough analysis, results must be published fro the public to see irrespective of whether it agrees or disagrees with the original hypothesis.

Altering an experiment in order to achieve the desired result is grossly irresponsible, as this eliminates the objectivity that should be the main goal of every experiment. Bias must be eliminated from every scientific experiment.

Chromosomes only exist inside gametes true or false
netineya [11]

The male human has a sperm cell and the female has an egg cell. The cells from the male and female that combine to form a zygote are called gametes. The human sperm and egg cells each contain 23 chromosomes. . A combination of gametes forms a zygote with 46 chromosomes. The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.<span>Chromosomes get shuffled when eggs and sperm are made. Though most adult cells contain two sets of chromosomes, sperm and egg cells are different. These special cells have just one chromosome from each pair. Which chromosome they get from each pair is random, making each sperm or egg cell unique. There is also a bit of mixing before the chromosomes are sorted into individual sperm or egg cells. Chromosomes from each pair in a mother or father, respectively, make contact and exchange pieces of DNA, creating hybrid chromosomes. </span>
