Answer:
24 * 10 ^ 13 electrones
Explanation:
Tenemos la siguiente información;
Carga en un solo electrón = -1.6x10-19 C
Carga en el electrón en consideración = -38 uC o -38 * 10 ^ -6 C
Ahora,
si la carga en 1electron es -1.6x10-19 C
x electrones tienen una carga de -38 * 10 ^ -6 C
X = -38 * 10 ^ -6 C / -1.6x10-19 C
24 * 10 ^ 13 electrones
Answer;
-Kinetic energy
Explanation;
The energy associated with motion or movement is called kinetic energy.
-Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy is stored energy and the energy of position; gravitational energy.
-An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. Kinetic energy is calculated by the formula 1/2mv², where m is the mass of the object and v is the velocity of the object.
-Therefore, kinetic energy depends upon two variables: the mass (m) of the object and the speed (v) of the object.
Answer:
B -Scenario 1, because chance events led to a decrease in the number of dark
Scenario 1, because chance events led to a decrease in the number of darkbeetles.
<u>Answer:</u>
Pfr and phytochrome would be analogous to mammalian opsins in their light-sensing ability.
<u>Explanation:
</u>
- Phytochromes are proteins which are 'sensitive to light', and are able to detect light sources on the plant body.
- These form an integral part of the leaves of a plant body.
- These proteins are made up of two forms: Pf and Pfr. Pf exists in an inactive form of phytochrome which activates in the presence of light to form Pfr which is an active form.
- This Pfr induces a cellular response in the plant. Similar to the opsins in Mamalian eyes, these also change in structure when exposed to light.
- Hence, Pfr and phytochrome are the molecules which can be analogous to 'mammalian opsins' in their 'light-sensing ability'.
<h2>
The nerve impulse signal will move towards synapse.</h2><h2>
Explanation:</h2>
The electrical charge travel through the neural cell membrane and thus generates a nerve impulse. The nerve impulse travels through membrane of neural cell by the movement of ions across the membrane. The nerve impulse signal will travel through the neuron and reaches at the end of a neuron that is axon terminal. The end (axon) of a neuron connects with the dendrites of second neuron with the help of molecules known as neurotransmitters. This connection between two neurons that allows the nerve impulse to travel is called synapse.
