Answer:
Fluorescent labeling of cells helps in ensuring more visibility of the properties of the cell.
The equipment used in studying fluorescence-labelled cells include epi-fluorescence microscope which helps in providing a more dimensional view of the cells. The spectrophotometers is also used to determine the chemical properties of the cells through the intensity of light measured with this equipment. The flow cytometer is also used in this process.
What is in the cloud of negatively charged particles that surrounds an atom?
O A. Neutrons
B. Protons
C. Proteins
O D. Electrons
Answer:
electrons
Explanation:
bc i know big brain stuff
Answer:
D
Explanation:
We are looking for a negatively charged particle that is part of the cloud around an atom. Let’s analyze each answer choice.
Neutrons are neutral, and they have no charge. Therefore, A is incorrect.
Protons have a positive charge, so B is also incorrect.
Proteins are not part of the atom or in the cloud that surrounds one, so choice C is wrong as well.
Electrons are negatively charged, and they are in the cloud that surrounds an atom. Therefore, D. Electrons is correct.
The inheritance pattern of a recessive maternal effect gene in Drosophila. In maternal effect, the offspring’s phenotype is under the control of nuclear gene products present in the mother's egg. In this example, the presence of the a + allele in the mother is required for proper wing development in the offspring. In the pedigree, individuals who are wingless are indicated by a shaded symbol. The phenotypes and genotypes are only provided for the first generation (individuals 1 and 2).What are all the possible genotypes for individual 1's mother?
1. mom-a/a dad-a+/a
2. offspring: a+/a or a/a
1. a +/a +
2. a +/a
3. a/a
Answer:
m,m

Explanation:
Single Antigen, Multiple Organs Some Type-II immunopathology mediated autoimmune diseases have manifestations in multiple different organs. Discuss how antibodies to one single antigen can cause damage in multiple sites throughout the body. Things you might discuss include, but are not limited to where the antigen could be expressed, how antibodies are made, how they bind antigen, where they circulate, the ratios of antigen to antibody, mechanisms of the immune system that result in cellular/tissue damage, or how immune system components can affect other organs. You might also comment on what makes one antigen an attractive target rather than another. Please do NOT comment on all the things listed above, they are just to get you thinking. If you are having trouble getting started, it might help to think about a specific disease which affects multiple organs... Good Luck!
Answer:
Adaptive immune responses are triggered by activation of antigen-specific T cells that produce antibodies against foreign antigens such as, for example, harmful viruses. These immune responses are useful to eliminate dangerous molecules from the body. In a normal immune reaction, the antibodies produced by T-cells target antigen molecules in order to be subsequently absorbed by phagocytic macrophage cells.
Autoimmune diseases are triggered by the response of the adaptive immune system against self-antigen molecules. Since the immune system can not eliminate antigens from the own body, this immune reaction generates an excessive inflammatory response, and it may lead to the damage of tissues and organs.
