Answer:
Ventricles
Explanation:
Answer: By increasing the rate of reaction by lowering the activation energy.
Explanation:
A catalyst can be defined as the substances that can increase the rate of reaction by lowering the activation energy. This saves more energy for the reaction to take place.
The rate of reaction can be increased by several factors such as temperature, pH and catalyst.
Some of the catalyst are: Enzyme, molybdenum.
B. some catastrophic event greatly reduces the size of a population
C. the gene pools of different populations have become very diversified
D. members of different populations can no longer mate successfully
An antigen is a biomolecule, such as a protein or sugar, that binds to a specific antibody. An antibody/antigen interaction may stimulate an immune response. Not every biomolecule is antigenic and not all antigens produce an immune response. B cells are the major cell type involved in the humoral immune response.
The key biomolecule involved in the immune system is a protein known as an antibody. These are produced by B cells and help the immune system recognize and destroy foreign substances like bacteria or viruses.
The biomolecule that has significant involvement in the immune system is a group of proteins known as antibodies or immunoglobulins. These antibodies are produced by certain types of white blood cells (B cells). They play a crucial role in the immune response by recognizing and binding to specific antigens such as bacteria or viruses, enabling other parts of the immune system to destroy these foreign substances more effectively. For example, if a person becomes infected with a virus, the immune system will produce antibodies specific to that virus. Once these antibodies attach to the virus, they basically mark it for destruction by other cells in the immune system.

Answer: B retina
Explanation:
Bipolar cells connect the inner and outer retina. They transfer information to ganglion cells.
Plant pigments function like a team, with each pigment absorbing a different light wavelength to collectively ensure the plant efficiently captures and uses light, similar to players in a sports team playing different positions but working together to win.
Plant pigments, like teammates on a sports team, each have a unique role, but they work together for a common goal. In plants, the goal is to absorb and utilize light energy for photosynthesis. The most well-known plant pigment is chlorophyll, which absorbs blue and red light. Other pigments such as carotenes and xanthophylls absorb different light wavelengths, collectively helping the plant to capture as much light energy as possible. Just like a sports team where each player has a different position but all work together to win the game, the pigments in plants function in unison to ensure the plant efficiently captures and uses light.

Plant pigments operate like teammates on a sports team, where each pigment absorbs different light wavelengths. The collaboration of these pigments ensures efficient light absorption and energy conversion, like teammates working together for a common goal.
Plant pigments operate very much like teammates on a sports team where each player has a unique role. Various pigments absorb unique wavelengths of visible light, much like different players on a sports team have unique roles, but work together to achieve the common goal. The most common pigment is chlorophyll, which is green and absorbs red and purple light. The light's energy is then used in photosynthesis, the equivalent of scoring a goal in the game.
Other pigments include bacteriochlorophylls, carotenoids, phycocyanins, and phycoerythrins, each absorbing different wavelengths and contributing to the plant's ability to absorb energy from more wavelengths. In places where sunlight is competitive, having various pigments ensures plants can maximize the absorption of light, much like having players with different strengths on a sports team ensures all areas of the game are covered.
These pigments work together to ensure that the plant can thrive in its environment. This collaboration is similar to how different players on a sports team work together to apply different strategies and tactics to win the game.
