Superficially, the connection between the cell cycle and cancer is obvious: cell cycle machinery controls cell proliferation, and cancer is a disease of inappropriate cell proliferation. Fundamentally, all cancers permit the existence of too many cells.

Desmosomes form channels that allow each cardiocyte to electrically stimulate its neighbors. True False
dimulka [17.4K]

Answer:

False

Explanation:

The most specific feature of cardiac muscles is the presence of intercalated discs. Intercalated disc connects the ends of cardiac muscle fibers to one another. The discs have desmosomes and gap junctions. The function of desmosomes is to hold the cardiac fibers together. The gap junctions of cardiac fibers allow muscle action potentials to spread from one cardiac muscle fiber to another. These gap junctions have tubular connexons that form channels and connect the cytosol of adjacent cardiocytes to allow the flow of ions and spread of action potential from one cell to another.

Without undergoing any changes itself, the _____ makes changes to the ______.
BigorU [14]

Without undergoing any changes itself, the enzyme makes changes to the substrate.

<h3>What is an enzyme?</h3>

An enzyme is a biological catalyst that acts by lowering the activation energy in a chemical reaction.

In a chemical reaction, an enzyme binds to a substrate to convert it to one or more products.

In conclusion, without undergoing any changes itself, the enzyme makes changes to the substrate.

TRUE OR FALSE : Cohesion is when water molecules stick to OTHER substances.
tekilochka [14]

Answer:

true

Explanation:

Thus when the positive side on one water molecule comes near the negative side of another water molecule, they attract each other and form a bond. This "bipolar" nature of water molecules gives water its cohesive nature, and thus, its stickiness and culpability

If you ate more food from secondary consumers, how would this change the percentage of the biomass pyramid necessary to support
Anna007 [38]

Answer:

would increase

Explanation:

The pyramid of biomass is a diagram that exhibits the total biomass of the organisms at different trophic levels, which are required to support life in a given ecosystem. This pyramid usually starts with producers situated on the bottom (e.g., plants), then continues with the organisms that eat these primary consumers (herbivores), after with secondary consumers (carnivores), and so successively. The pyramid of biomass indicates the amount of mass of 1-primary producers required to support the life of the primary consumers, 2- primary consumers needed to support the life of the secondary consumers, 3-secondary consumers needed to support the life of the tertiary consumers, and so successively for each trophic level. In this diagram, the trophic level with a higher amount of biomass (and energy) is usually represented by the producers (i.e., by organisms on the bottom), and this amount of biomass decreases as long as more levels are considered. In consequence, if more food from secondary consumers is consumed, it will produce an increase in the percentage of biomass that is needed to support life.
