Research with embryonic stem cells has become the great hope of doctors and scientists worldwide. However, because they deal with embryos, they have also become the subject of controversy.

The discovery that human embryonic stem cells can be isolated and propagated in the laboratory, with the potential to develop in all tissues of the body is an important advance in medicine. But it has raised ethical concerns. Scientists now know that stem cells are also present in adults. If there was a way to stimulate resident stem cells to replace cells that are dying, the limitations of transplantation could be overcome, as well as ethical problems.

Stem cells are cells that have the ability to divide indeterminate periods into culture and give rise to several types of specialized cells. They can become blood, bone, brain, muscle, skin, and other organs. Embryonic stem cells are undifferentiated cells that have the ability to form any adult cell.

As examples of ethical problems, the following questions can be cited:

  • Is it appropriate to use embryos produced for reproductive and unused uses, whose legal time limits have been exceeded, to generate embryonic stem cells?
  • Is it acceptable to produce non-reproductive human embryos only to produce stem cells?
  • Is it fair to create a climate of expectation for patients and patients' families about the possibility of therapeutic use of cells that have not even been tested in basic experiments?

Although it is a polemic subject and it needs to be studied very much, it is not right to see the stem cells as evil and immoral. Stem cell research seeks to develop a technology that can end the suffering of thousands of people around the world, so we must encourage this type of research and try to establish arguments that can answer the ethical questions about this subject.

How are all animals alike as heterotrophs
jeka57 [31]

Answer:

All animals alike as heterotrophs beacuse animals cannot prepare their own food.

Explanation:

Heterotrophs may be defined as the organisms that will depend upon plants or other animals for their food. They are unable to synthesize their own food.

All animals are heterotrophs as they depends on the other organisms for the production of food. All animals are also referred as consumers.

Fruit color in a particular plant is controlled by a set of three quantitative trait loci (i.e., QTLs or polygenes), that work i
tankabanditka [31]

Answer:

1/8

Explanation:

Given that the trihybrid parents have AaBbCc genotype for fruit color. The trait is a quantitative trait i.e. each dominant allele will have an additive effect on it. In this case, AaBbCc and AABBCC will not produce same fruit color because AaBbCc has only three loci contributing to the color while in AABBCC all the six loci are contributing to the color. For an offspring to be exactly similar to the AaBbCc parents it should have the same genotype of AaBbCc.

The probability of Aa to come from a cross between Aa and Aa is 2/4 or 1/2

The probability of Bb to come from a cross between Bb and Bb is 2/4 or 1/2

The probability of Cc to come from a cross between Cc and Cc is 2/4 or 1/2

So the collective probability of AaBbCc offspring from a cross between AaBbCc and AaBbCc parents would be=

1/2 * 1/2 * 1/2 = 1/8

Hence, assuming no effects of the environment, 1/8 of the offspring will have the same fruit color phenotype as the trihybrid parent.

Which of the following best describes the cell cycle?
zhenek [66]

Correct answer: B). Cells spend the most time in interphase, where they grow and their DNA replicates.

The cell spends its most of the time in the interphase, during this phase of growth, cell continues to grow and carry out its metabolic activities which are necessary for regular growth and maintenance.

During this phase of the cell cycle, a lot of protein is synthesized in order to double its size. The important changes that occur in this phase include DNA duplication and division of chloroplast and mitochondria.

Hence, the correct answer would be option B.
