Law of Conservation of Energy
The Law of conservation of energy states that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.
Answer:
The eukaryotes, bacteria, and archaea that live in and on the human body are called normal microbiota. When they were originally discovered, scientists thought that the relationship between these organisms was parasitic because they thought that the organisms benefit from living on the host but did not help the host. In recent years, researchers have determined that most of our resident microbes derive and give benefit to the host. This makes the relationship between host and microbe one of mutualism. Pathogenic, on the other hand, are microbes that cause diseases.
Answer:
The correct answer would be -
RGCB daughter - 0%
RGCB sons - 100%
Explanation:
Red-green color blindness is a sex-linked recessive disease that means it will only express in absence of the normal allele that is present on X-chromosomes. As it is known that males have only one X-chromosomes therefore, the chances are more in males to be affected in presence of the recessive gene. In this given case women s RGCB and man has normal vision. The genotype of women would be both recessive alleles XcXc and genotype of man would be XY.
The gametes would be - Xc, Xc and X, Y
then the cross:
Xc Xc
X XXc XXc
Y XcY XcY
so the offspring would be -
Carrier female = XXc (50% chance in total and 100% in daughters)
RGCB daughters = 0%
RGCB male = XcY (100% in sons and 50% of total children)
Hello, I figured that the question was missing its options so I went online to find them. Here they are:
All of the following are true of the thymus gland, except that:
A) activates B cells.
B) reaches its greatest relative size during the second year of life.
C) involutes after puberty.
D) produces T cells.
E) lies in the anterior mediastinum
Answer:
The correct answer is: A) activates B cells.
Explanation:
The thymus is a lymphatic organ that is located in the anterior superior mediastinum (a compartment in the thoracic cavity), in front of the heart, with the function to mature T cells (one of the types of lymphocytes, white blood cells very important for the functioning of the immune system).
The thymus is more active and bigger during childhood, when puberty hits it involutes and its functional tissue is replaced with adipose tissue (fat).
<u>B cells are not activated in the thymus, they mature in the bone marrow</u>.
Proteins are one of the four main types of Organic molecules.Organic compounds are those compounds that have carbon atoms. There are four important classes of organic molecules.which includes; Carbohydrates, lipids, proteins, and nucleic acids.
