A weight-training program that gradually increases the resistance lifted relies on the progression principle to build strength, where strength is the amount of force a muscle can exert.
The principle of progression states that you should overload gradually and that <span>there is a perfect level of overload in-between a too slow increase and a too rapid increase.</span>
The Inconsistencies of the data are led to further investigations conclude about data that are inconsistent with the current, scientific understanding of amphibian reproduction
Option B
<h3><u>Explanation:</u></h3>
Class amphibia is one of the classes under the phylum chordata. This class has typical reproductive features. They are the animals that can live in both land and water, and a few are exclusively aquatic. But they essentially need water for the fertilization process. This is because they generally undergo external fertilization and the females lay eggs beside the water body. The males eject the sperms in water which swim through the water into the eggs and fertilize them.
This is the days old theory regarding the amphibia fertilization. But if some new theory comes up someday, that readily don't exclude this theory. The new theory has to pass through several tests and various further investigations where it's seen if the new theory explains most of the amphibia reproduction or not. Then it can be approved along side with the old theory.
Meiosis is the type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells this process is required to produce egg and sperm cells for sexual reproduction
Answer:
Humoral immunity involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood.</u>
Explanation:
Humoral immunity is defined as the immunity which is mediated by several macromolecules presnet in the extracellular fluids such as antibodies, certain antimicrobial peptides, and complement proteins.
Humoral immunity allows to distinguishes two groups of foreign substances. it involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood. </u>
Humoral immunity begins when an antigens bind to B cells. Interleukins or helper T cells provides a secondary signal to the B cells that activates a B cell and allows B cell proliferation. which roduces produce plasma cells. The plasma cell then produces antibodies which are identical to the specific antigen. The antibodies are the released and circulate through the body, binding to antigens. B cells the further produces memory cellss for future immunity.
So, Humoral immunity involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood.</u>
Circulatory system.....circulates blood (a vital delivery system of oxygen) throughout the whole body when tissues need it the most and with a constant supply.
