Nonspecific lymphocytes that spontaneously attack and kill cancer cells and cells
infected by microorganisms are known as
O antibodies.
O lymphocytes.
O macrophages.
O natural killer cells.

Answers

Answer 1

Answer:

Antibodies.

Explanation:

An antibody is a protein produced by the white blood cells of an organism to resist harmful foreign substances, so-called antigens. Once the body has done this once against an antigen, it will usually develop immunity to the disease that the antigen represents. A common vaccination method is to supply the body with small amounts of unknown antigens, thus stimulating the body to produce anti-inflammatory antibodies.  In some cases, antibodies can react to harmless substances, causing an allergic reaction.

Answer 2

Answer:

lymphocytes

Explanation:

These cells provide efficient, specific and long-lasting immunity against microbes and are responsible for acquired immunity. Lymphocytes differentiate into three separate lines: thymic-dependent cells or T lymphocytes that operate in cellular and humoral immunity, B lymphocytes that differentiate into plasma cells to secrete antibodies, and natural killer (NK) cells. T and B lymphocytes are the only lymphoid cells that produce and express specific receptors for antigens.

T Lymphocytes: These cells are involved in the regulation of the immune response and in cell mediated immunity and help B cells to produce antibody (humoral immunity). Mature T cells express antigen-specific T cell receptors (TcR) that are clonally segregated (i.e., one cell lineage-one receptor specificity). Every mature T cell also expresses the CD3 molecule, which is associated with the TcR. In addition mature T cells display one of two accessory molecules, CD4 or CD8. The TcR/CD3 complex recognizes antigens associated with the major histocompatibility complex (MHC) molecules on target cells (e.g. virus-infected cell). The TcR is a transmembrane heterodimer composed of two polypeptide chains (usually, α and β chains). Each chain consists of a constant (C) and a variable (V) region, and are formed by a gene-sorting mechanism similar to that found in antibody formation. The repertoire is generated by combinatorial joining of variable (V), joining (J), and diversity (D) genes, and by N region (nucleotides inserted by the enzyme deoxynucleotidyl-transferase) diversification. Unlike immunoglobulin genes, genes encoding TcR do not undergo somatic mutation. Thus there is no change in the affinity of the TcR during activation, differentiation, and expansion.

How do you think the way the fibers are arranged contributes to the strength of the cell wall

Answers

The more organized and uniform the arrangement of fibers, the stronger the cell wall will be. The distribution of cellulose microfibrils is important for plant cell wall growth and development. The orientation of microfibrils varies during different growth stages, thereby influencing the properties of the cell wall.

The arrangement of the fibers in the cell wall contributes significantly to its strength. Cell walls of plants are mainly made of cellulose, hemicellulose, pectin, and lignin. Cellulose is the primary component and is made of glucose monomers arranged in long chains.

These chains are organized in a crystalline structure called microfibrils. The arrangement of these microfibrils plays a vital role in the strength of the cell wall. Cellulose microfibrils are arranged in a cross-linked network, which is laid down as concentric layers around the cell.

The fibers of each layer are oriented at angles that differ from the fibers in adjacent layers. This arrangement is responsible for the exceptional strength of the cell wall against mechanical stress. It provides mechanical strength to the cell and offers resistance against bending, stretching, and compression.

The orientation of the fibers also determines the mechanical properties of the cell wall. It affects how the cell wall responds to stress and determines its plasticity and elasticity.

You are using the lensometer to read the power in a lens in which the three sphere lines become clear with the power drum reading +1.25 and with the axis wheel reading at 138. Moving the power wheel, the three-cylinder lines come clear at a power drum reading of -4.00. Which of the following would be the correct prescription from this lens? Select one: +1.25 -5.25 x 138 -4.00 +1.25 x 138 +1.25 -4.00 x 138 -5.25 +1.25 x 138 ​

Answers

Answer:

The correct prescription from this lens would be: +1.25 -4.00 x 138

Explanation:

This is because the power drum reading of +1.25 represents the spherical power of the lens and the -4.00 represents the cylindrical power of the lens. The axis wheel reading of 138 represents the axis of the cylindrical power. The correct prescription for the lens is written in the format of spherical power, cylindrical power, and axis.

The correct prescription from this lens would be +1.25 -4.00 x 138.
The first number, +1.25, is the sphere power of the lens, which is the power drum reading when the three sphere lines become clear. The second number, -4.00, is the cylinder power of the lens, which is the power drum reading when the three cylinder lines become clear. The final number, 138, is the axis at which the cylinder power is oriented, which is the reading on the axis wheel when the three cylinder lines become clear.

one hour of outdoor vigourous exercise can require approximatelt what percent increase in the amount of water the body uses

Answers

An hour of strenuous outdoor activity might raise sweat production by 10% to 20%.

Our health depends on getting enough water, and staying hydrated while exercising is crucial. Dehydration, especially if we are exercising in hot weather, can cause cramping, soreness, fatigue, and even heat stroke. Without adequate hydration before and after exercise, we run the risk of developing major health issues.

According to the U.S. National Academies of Science, Engineering, and Medicine, a sufficient intake of total beverages per day for males is 3.7 liters and for women is 2.7 liters, including water. To make up for the fluids lost through perspiration, one should, nevertheless, consume additional liquids while exercising.

Men sweat more than women and need more water, yet while working at the same relative intensity, women have the same physiological reactions as men. Women who have been properly acclimatized to the heat exhibit the same physiological reactions to hot, humid weather as men do.
