Photovoltaic (PV) cells primarily rely on photons and electrons for activation. Photons, which are particles of light, strike the solar cell and excite electrons in the semiconductor material, typically silicon. This excitation allows the electrons to move freely, creating an electric current when collected by the cell's conductive layers. Thus, the interaction between photons and electrons is essential for the operation of PV cells.

What two responses do helper T cells activate to fight viruses?
Helper T cells activate cytotoxic T cells to directly kill virus-infected cells and activate B cells to produce antibodies that can neutralize viruses. This dual response helps to eliminate the virus from the body efficiently.
What are two sex cells that are needed for sexual reproduction?
Spermatzoon (sperm)Ovum (egg)
What term is used to describe the minimum energy needed by particles when they collide?
State the term used to describe the minimum amount of energy required for two colliding particles to rate
What do cells do to activate nucleotides for incorporation into a polymer?
Cells activate nucleotides for incorporation into a polymer by converting them into their triphosphate forms, such as ATP, GTP, CTP, and UTP. This activation typically involves the addition of two phosphate groups to the nucleotide, which is catalyzed by specific enzymes. The triphosphate form provides the necessary energy for polymerization during processes like DNA or RNA synthesis, facilitating the formation of phosphodiester bonds between nucleotides in the growing polymer chain.
What two particles are found in matter?
the two particles found in mater is gas and air.

Helper T cells activate cytotoxic T cells to directly kill virus-infected cells and activate B cells to produce antibodies that can neutralize viruses. This dual response helps to eliminate the virus from the body efficiently.
What are the two materials that are carried by blood to the cells of the body?
Food particles and oxen.
How many parent cells will be needed to reproduce sexually?
Two

What term is used to describe the minimum energy needed by particles when they collide?
State the term used to describe the minimum amount of energy required for two colliding particles to rate
What charge particles would repel one another?
Two particles that have a charge of the same sign - that is, either two positive particles, or two negative particles.
Which two systems are directly involved in providing molecules needed for the synthesis of fats in the human cells?
1. digestive and circulatory
Specific immunity is controlled by two types of lymphocytes called?
Specific immunity is primarily controlled by two types of lymphocytes: T cells and B cells. T cells are responsible for cell-mediated immunity, helping to directly kill infected cells or activate other immune cells, while B cells are involved in humoral immunity, producing antibodies that target specific pathogens. Together, these lymphocytes play a crucial role in the adaptive immune response, providing long-lasting protection against infections.
What two materials does your heart bring to your cells that are needed for respiraton?
oxygen through blood is one. I do not know the other. Try Google.
What type of cells are sex cells?
Sex cells, also known as gametes, are specialized cells that are involved in sexual reproduction. In humans, the two types of sex cells are sperm in males and eggs (or ova) in females. These cells each carry half the genetic material needed for reproduction.
