Inheritance of Traits by Offspring Follows Predictable Rules. Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.
This type of water transition or change in phase of matter is known as FREEZING.
Water has molecules that are free flowing and have the ability to collide and bounce against each other, that's why it has that kind of characteristic that it takes the shape of its container.
When these molecules are exposed to lower or colder temperatures, the molecules tend to vibrate and get attracted towards each other, creating a semi-solid or completely solid material. In this example, liquid turned into frost because of the low temperature present within the environment.
The stem of the plant should be cut at least three to four centimeters above the surface level.
The stem should be tightly fixed into the glass capillary.
All connection should be made air-tight by using paraffin.
Initial and final readings should be carefully noted.
Answer:
C. Organisms are capable of producing food without light.
Explanation:
this is the best answer because mostly bacteria live in the the bottom of the ocean. and they feed on dead organisms who have already harnessed the sun's light to create food.
Answer:
The stem cells possess two cardinal characteristics, that is, self-renewal and differentiation. The examples are embryonic stem cells and hematopoietic stem cells. The genetically determined immunodeficiency in a person is generally a result of the defective gene in the hematopoietic stem cells that produce red blood cells, white blood cells, and other components of blood.
The examples of genetically determined immunodeficiency diseases are SCID, X-linked Agammaglobulinemia, and others. The individual suffering from genetically determined immunodeficiency exhibits a defective gene in hematopoietic stem cells. There are two methods of treatment, that is, stem cell therapy and gene therapy.
The procedure of stem cell transplantation generally comprises HLA matching, in which the main step is to prevent graft rejection. It is succeeded by harvesting of hematopoietic stem cells from the HLA matched donor. The step of conditioning is performed to eradicate the recipient HSCs by radiotherapy and chemotherapy succeeded by the transfer of harvested donor HSCs to the patient or the recipient.
A person cannot receive his own stem cells as his or her each and every cell is defective in that specific gene accountable for the disease.
