How can the amount of energy absorbed by Earth's surface change?

Answers

The earth-atmosphere energy balance is the balance between incoming energy from the Sun and outgoing energy from the Earth. Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth's surface.

katelyn is working on a project about classifying cells as either prokaryotic or eukaryotic. she is observing a cell under an electron microscope that does not have a cell wall but does have a nucleus. how should katelyn classify this cell? A. as a prokaryotic cell B. as a eukaryotic cell C. there is not enough info to classify this cell D. the cell had components of both types

Answers

I would say B. an eukaryotic cell!

A eukaryote can be a plant or animal cell. They have a nucleus and animal cells do not have a cell wall. So specifically probably an animal cell but for this question an eukaryotic cell is the answer!

A prokaryotic cell lacks a nucleus but do have a cell wall but this can’t be the answer because of the lack of a nucleus.

So B! Eukaryotic cell! Hope this helped!

Katelyn should classify this cell as a eukaryotic cell. The presence of a nucleus is a defining characteristic of eukaryotic cells, while prokaryotic cells do not have a nucleus. The absence of a cell wall is not enough to classify a cell as prokaryotic, as some eukaryotic cells also lack cell walls.

What are eukaryotic cells?

Eukaryotic cells are cells that have a distinct membrane-bound nucleus and other membrane-bound organelles that carry out specific functions. These cells are typically larger and more complex than prokaryotic cells, which lack a nucleus and organelles.

Eukaryotic cells are found in plants, animals, fungi, and protists. They are characterized by their compartmentalization, meaning that various parts of the cell are separated by membranes, allowing for specialized functions to be carried out within specific areas of the cell.

Examples of eukaryotic organelles include the mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes.
