Alexus [3.1K]

Answer:

B) Coating of microbe to aid phagocyte recognition

Explanation:

Opsonization is the process and mechanism which targets the foreign body and helps in the recognition of the pathogen by the phagocytic cells such as the macrophages and dendritic cell.

The opsonization enhances the process of phagocytosis as the opsonin substances which could be the antibodies, proteins or other molecules which could be easily recognised by the phagocytic cells gets attached to the pathogen.

Thus, Option-B is the correct answer.

Opsonization is the coating of a particle with proteins that facilitate phagocytosis of the particle by tissue macrophages and activated follicular dendritic cells (FDCs) as well as binding by receptors on peripheral blood cells

gizmo_the_mogwai [7]

Answer:

agouti - aaBbCc

solid color - AaBBCC

agouti black - AAbbCc

albino - AaBbcc/Aabbcc/AABBcc

Explanation: All the phenotypes that contain cc will be albinos, so they won't present any pigment deposition. Agouti black depends on the A gene to be homozygous and the B to be recessive, so the phenotype AAbbC_ is the correspondent. If A is not homozygous and B isn't recessive, we have agouti color. If B is homozygous and A recessive, we have a solid color.

Why is Type O- the universal donor? Check all that apply.
Ksivusya [100]

The Type O blood group is commonly called as universal donor because any blood group can receive the O blood group. The blood group O has no antigen. Due to the absence of antigen it doesn't agglutinate when come in contact with other blood groups in the plasma.

The agglutination reaction happens when opposite antigen and antibody reacts with each other. e.g.- Blood group A contains antigen A and antibody b and the blood group B contains antigen B and antibody a. Agglutination reaction occurs when the antigen A reacts with antibody a. As O blood group has no antigen, agglutination reaction doesn't occur.

Ede4ka [16]
The correct terms to fill in the blanks are lateral ventricles and venous sinus blood. Cerebrospinal fluid (CSF) is formed by lateral ventricles and reabsorbed through arachnoid granulations into the venous sinus blood. The CSF is a fluid that is clear and colorless found in the spinal cord and in the brain, generally the central nervous system. The CSF functions as a buffer or a shock absorber for the brain. It provides basic mechanical protection for the brain. Also, it helps in the circulation of nutrients and the chemicals that are filtered and aids in the elimination of waste products.
