Answer:
Be
Beryllium
Explanation:
number of protons = atomic number.
number of electrons = atomic number
Answer:
"C" is the answer, Myosin would be able to bind to bind to the exposed binding sites on thin filaments but would not be able to detach
Explanation:
ATP is required for muscle contractions. muscle fatigue results in the decline of muscle force generated over time during metabolic fatigue there is depletion of required substrate such as ATP or glycogen as muscle is not able to generate energy to power contractions. accumulation of metabolites from this reaction other than lactic acid or reactive oxygen species can also induce fatigue by interfering with the release of Ca++ from the sarcoplasmic recticulum.
Of these options, it's often observation that is most likely to result in an inaccurate prediction, since objectivity plays a role. It's helpful to have more than one person observe at once.
Answer:
- Dependent variable: number of cells that are in one of the phases of mitosis
Explanation:
In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.
Answer:
sieve-tube elements, companion cells
Explanation:
Sieve-tube elements and companion cells are responsible for the movement of photosynthes through a plant.
The sieve tube elements are shorter (almost organelle-free) living cells, placed end to end, forming the sieve tubes. Their transverse cell walls are called sieve plaques that make connections between cells and through openings called sieves establish the connection between the cytoplasm of adjacent cells. Each sieve is coated with calose (glucose polymer), which in winter can completely clog the vessel and then dissolve in spring. When infections occur or the vessel is parasitized, it can also be clogged with callose.
Companion cells are specialized parenchymal cells, which contain all the components that exist in living cells, including the nucleus, are the cells most closely linked to the sieved tube element. The Screened Tube Element and its companion cells are related in development, are derived from the same mother cell, and have several cytoplasmic connections to each other. Due to the many connections, the potential function of the companion cells is to release substances into the sieved tube element and, when the nucleus is absent, to include information molecules, proteins and ATP. When a screened element dies, its companion cells also die, which is a demonstration of this interdependence.
