Give differents between lytic and lysogenic cycles
Answer:
the spread of the viral DNA
Explanation:
The difference between lysogenic and lytic cycles is that, in lysogenic cycles, the spread of the viral DNA occurs through the usual prokaryotic reproduction, whereas a lytic cycle is more immediate in that it results in many copies of the virus being created very quickly and the cell is destroyed.

The image shows a rain forest ecosystem. The energy from plants, or producers, acts as the starting point of energy in the ecosystem. This energy is transferred to other organisms in the food web. In which two ways is the total amount of energy conserved in the ecosystem?
Some energy is transferred to the organisms, and the remaining energy is released into the ecosystem as thermal energy.
Bacteria eat the dead bodies of organisms to release the organisms’ stored energy into the atmosphere.
Some energy is transferred to the smaller organisms, and the rest is stored in the bodies of larger animals.
Some energy is transferred to the organisms, and the rest is released by plants in the form of carbon dioxide.
Bacteria eat the dead bodies of organisms, obtain all the energy, and store it in their bodies.

What might happen if a coral species that is well adapted to higher temperature was introduced into a coral reef habitat?
Answer:
May die eventually
Explanation:
A coral species which is living in a regions of high temperature will not be able to be in symbiotic relationship with algae at normal temperature of the sea side coral reefs and may expel it out. A long lasting exposure to change in temperature will lead to bleaching, turning corals white and ma eventually cause death.

1. The closest star to earth is actually Sun at 93,000,000 miles (150,000,000 km).
2. Stars are different colors such as blue, white, yellow, orange, and red. The color indicates the star's temperature in its photosphere, the layer where the star emits most of its visible light. Thus the correct option is B.
What is star?
A star is a luminous ball of gas containing hydrogen and helium, held together by its own gravity. Nuclear fusion reactions in its core support the star against gravity and produce photons and heat, as well as small amounts of heavier elements.
3. Sirius star also known as the Dog Star or Sirius A, is the brightest star in Earth's night sky. Thus the correct option is D.
4. Stars vary in their mass, size, temperature, color, luminosity, and age. They differ in their distance from earth, and some orbit one or more other stars. The stars differ from each other brightness.
5. Small groups of stars are called star systems, and somewhat larger groups are called star clusters. There are even larger groups of stars, called galaxies. Thus the correct option is D.
Our solar system is in the Milky Way Galaxy, which is just one galaxy in the universe. The patterns of stars seen in the sky are usually called constellations, although more accurately, a group of stars that forms a pattern in the sky is called an asterism.
6. Stars rising in the East, passing overhead, and setting in the West.
Thus the correct option is A.
7. This motion is due to the Earth's rotation. As the spin of the Earth carries us eastward at almost one thousand miles per hour, we see stars rising in the East, passing overhead, and setting in the West. The Sun, Moon, and planets appear to move across the sky much like the stars.
Thus the correct option is D.
8. If you go as far north as the North Pole, you'll see Polaris directly overhead. As you travel south, Polaris drops closer to the northern horizon. If you get as far as the equator, Polaris sinks to the horizon.

Oxygen has an atomic number of 8. The n=1 energy level has two electrons, and the n = 2 energy level has six electrons. Oxygen's valence is _______.
● +2
● -2
● +1
● -1
Answer:
Oxygen's valence is +2
the answer is +2
I hope this helps
Answer:
● -2
Explanation:
Oxygen needs to gain 2 more electrons to have 8 electrons in outer most shell (octet rule). Gaining electrons makes you negative thus, oxygen gains 2 electrons and has valence of -2.
why people living in high altitude have level of RBC?
Answer:
Scientists have long known that the body adjusts to the oxygen-deprived conditions of high altitudes. ... The traditional explanation has been that low-oxygen conditions cause the body to build new red blood cells, making it easier to supply oxygen to muscles and vital organs.
