How are herbicides designed to harm plant cells but not human cells?
Systemic and target-specific formulations are ways in which herbicides are designed to harm plant -- not human -- cells. But in reality, it is difficult to comprehend and control all of the after- and side-effects of herbicides so environmentalists tend to speak of degrees of ambient residue and of harm to non-target organisms.
How do T cells destroy infected or diseased cells?
Cytotoxic T-cells kill infected cells in one of two ways: 1. By interaction with Fas ligand on T-cell with Fas molecule on target cell (induces apoptosis). 2. Release of lytic granules containing granzymes (also induces apoptosis) - For this, the T-cell needs to form pores in the target cell using perforin and granulysin.
In what ways are hormones and neurotransmitters similar to each other?
They both communicate messages in the body.
What are ways that plant cells are different from other eukaryotic cells?
Plant cells have chloroplasts. They have glyoxisomes and photosynthetic
What are 3 ways of how landforms affect communities?
It affect our jobs,driving and homes.
How do hormones leave the cell?
Most hormones reach target cells by blood . Some types of hormones reach target cells by other ways e.g. pheromones via air ; local hormones via diffusion etc .
What are processes affected by plant hormones?
A hormone is a chemical that affects the ways in which an organism functions; it is produced in one part of the plant (or animal) body but affects many other parts of the body as well. Hormones work by coming in contact with target cells, causing the organism to respond in various ways to the chemical signal. In plants, hormones usually work by influencing cell differentiation, elongation, and division. They also affect the timing of reproduction and germination. These hormones are divided int o five categories: auxins, cytokinins, gibberellins, inhibitors (or abscisic acid), and ethylene.
What are the main ways in which cells are able to communicate with each other?
through nerve impulses and hormones
What are the main ways in which animal cells are able to communicate with each other?
through nerve impulses and hormones
In what two ways do receptor proteins affect cellular activity?
Receptor proteins are intracellular proteins. Two ways in which they affect cellular activity are through inducement of transitions to cells and to speed up chemical reactions in cells.
What three ways does blood serve the body?
1. Gas Exchange... carrying oxygen from the lungs to the rest of the body, as well as carrying carbon dioxide from the body back to the lungs. 2. Pathway for transportation.... Carries hormones from the endocrine system so that they can act on their target cells. Carries nutrients to the cells of the body. Carries waste away from the cells of the body to be filtered by the liver and/or kidney. 3. Part of the immune system... Contains white blood cells and antibodies.

Why is microbiologist important?
Microbiologists study life processes that occur on the cellular level. This can mean the diagnosis and treatment of diseases caused by bacteria and viruses. It can also include studying the microscopic changes in plant and animal cells -- these can affect the ways that cells work, or how they affect other cells.
What does hormones and neurotransmitters not have in common?
They are both from different systems. Hormones are from the endocrine system and neurotransmitters are from the nervous system. They both also have different ways of how they communicate with the body to change or have a reaction. Hormones travel through the blood to the location that needs to be changed or balanced. Neurotransmitters travel along nerves. A third thing is that they affect the body differently. Hormones affect the systems that we generally don't notice, like our growth. Whereas neurotransmitters our typically immediately noticed, like tickling or pain.
