Answer: Lymph node
Explanation:
The lymphatic system of the body works by filtering the blood and remove the harmful pathogen that is present in it.
There are several organs in the lymphatic system that works together at different sites in the body and helps body prevent and cure from infection.
Lymph nodes function to remove pathogen and debris from lymph and it is also referred as filters of lymph. The macrophages and dentritic cells kill the harmful pathogen in the blood.
Hence, the correct answer is option A
Answer:
By analyzing the pelvis bone (sex determination) and the length of the diaphyseal bone and nonsynovial joints (age determination of non-adult skeletons and adult skeletons, respectively)
Explanation:
Bioarchaeologists are professionals that study human skeletons from archaeological sites. Bioarchaeologists can estimate the age and sex of human skeletons and thus determine the health and dynamics of past human populations. In regard to sex determination, the pelvis is a bone that can be used to estimate the sex of an individual with an accuracy higher than 95%. In regard to the age, characteristics associated with bone growth such as, for example, the length of the diaphyseal bone, can be good indicators to estimate the age of non-adult skeletons, while nonsynovial joints (i.e. joints without a synovial membrane) which are commonly called synarthroses or solid joints, can be used to estimate the age of adult skeletons.
Answer:
Diffusion is the net movement of any substance from a higher concentration region to the lower concentration region. It is conducting by a concentration gradient.
Osmosis is a process in which solvent (molecules) pass through a semipermeable membrane (SPM) from a lower concentration solution region to a higher concentration region so it equalizes the concentrations on each side of the SPM.
A <u>hypotonic solution</u> is a solution that has a higher concentration of solutes inside the cell than outside of the cell. Thus the movement of water is from outside to the inside of the cell.
A <u>hypertonic solution</u> is a solution in which solutes concentration is greater outside the cell and low concentration inside. The movement of water is from inside the cell to outside the cell.
An <u>isotonic solution</u> where two solutions having the same concentration inside and outside of the cell so there is free movement of molecules across a semipermeable membrane.
It should include information such as the history and mission of the firm, qualifications of the key staffs, program design, and the needed budget.
