Answer:

Answer:

Solar flares

Explanation:

  • The electromagnetic radiations that erupt from the sun and lasts for about a few minutes to a few hours are termed as solar flares.
  • This solar flare travels at the speed of light as it is an electromagnetic wave and thus, its effects are observed immediately as its emission is observed.
  • From the earth, the solar flare looks like a sudden flash of light coming from the sun that has increased brightness.
Answer 2
Answer: Solar Flares

Hope this helps!

Answers

Answer: C) carbon dioxide and water.

Explanation:

It should've ranked coupled with the release of energy. Because carbon dioxide and water are released into the atmosphere as byproducts of cellular respiration couple with the release of energy.

The first electrons to be excited by light energy are found in

Answers

The first electrons to be excited by light energy are found in Photosystem II (PSII). It is a specialized protein complex that captures the energy from sunlight and uses it to extract electrons from water molecules.Light is absorbed by chlorophyll, carotenoid and phycobilin pigments in the antenna regions. The excitation energy is rapidly transferred to the reaction centre domain.
Photosystem II is the correct answer

Why are catfish and carp found at the mouth of a river, while trout are found nearer the source?

Answers

Answer:

The correct reason would be "the levels of dissolved oxygen at the mouth of the river and at the source of the river".

The mouth of the river is the region where it flows into the ocean, lake, another river, reservoir, sea et cetera. The level of dissolved oxygen in this region is too low to support great biodiversity.

Organisms like catfish and carp can survive here due to their low oxygen demand. For example, catfish can survive in water with an oxygen content of 2.5 parts per million.

In contrast, the level of dissolved oxygen is higher at the source of the river. Organisms like trout are found here due to their high oxygen need. For example, rainbow trout require minimum 5-6 parts per million dissolved oxygen for its survival.
Catfish and carp require less oxygen than trout. The mouth of a river usually has less oxygen and the area closer to the source has more oxygen, so since catfish and trout require more oxygen they typically are found at the source.

The ________________ in males and the _____________________ in females are permanently blocked when an individual undergoes a sterilization procedure.a. testes; ovaries

b. testes; fallopian tubes

c. vas deferens; ovaries

d. vas deferens; fallopian tubes

Answers

Answer:

The ________________ in males and the _____________________ in females are permanently blocked when an individual undergoes a sterilization procedure.

a. testes; ovaries

b. testes; fallopian tubes

c. vas deferens; ovaries

d. vas deferens; fallopian tubes

Explanation:

I believe the answer would be B. This would be because the Fallopian tubes I think are tied which then would help so the sperm cannot go up to the ovaries. We know that it is A or B because the first answer being tested is correct.
