How energy from the sun is absorbed in earths atmosphere
Answer:
Explanation:
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system
Answer:
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.
Changes in the periodic table from 1800's to the present are based on all BUT ONE of these factors.
A)

B)
empirical data
C)
fact verification
D)
journal publication
Answer:
Journal Publication
Explanation:
Once empirical data has been verified, reviewed, only then can it be published in a scientific journal. As the periodic table was developed and reconfigured, data was constantly tested, reviewed, and finally used for modifications.
Changes in the periodic table from 1800's to the present are based on all but one of these factors is Journal Publication.
What is Journal publication?
Once empirical data has been verified, reviewed, only then can it be published in a scientific journal. As the periodic table was developed and reconfigured, data was constantly tested, reviewed, and finally used for modifications.
A scholarly publication is another term that may be used to describe a peer-reviewed article.
In order to maintain academic scientific excellence, the peer-review process involves having other specialists in the same field (peers) examine an author's scholarly work, study, or ideas.
Therefore, Changes in the periodic table from 1800's to the present are based on all but one of these factors is Journal Publication.

how are algae cells different from other cells
Answer:
In the case of the algae, each individual cell is responsible for absorbing its own water. This makes the algae nonvascular compared to the highly vascular plant species. In this connection, algae also lack several key structures that are normally present in ordinary plants like the leaves, roots and stem.
Algae are a group of aquatic organisms with autotrophic metabolism that are made up of eukaryotic cells and we can find unicellular or multicellular individuals.
Some characteristics of algae cells are:
• Cellular organization is eukaryotic (with the exception of blue-green algae), that is, they have a nucleus delimited by a double membrane, mitochondria, chloroplasts, endoplasmic reticulum, Golgi complex and lysosomes.
By definition, this type of cell is one that has a nucleus in which genetic material is stored. Compared to prokaryotic cells, eukaryotes have a large genome.
• The cell wall is made up mainly of cellulose and glycoproteins.
• In the algae cells we can find different reserve substances produced by metabolism.
The reserve substances are mainly starch, although we also find chrysolaminarin, laminarin, mannitol and paramilion in the different groups.
These substances form granules that are dispersed in the cell cytoplasm, in chloroplasts or in pyrenoids.
• They have structures of locomotion called flagella.
In different groups of algae, these organs vary in both number and shape, however, they typically present two flagella or multiples of two.
Therefore, we can conclude that algae are unicellular or multicellular photosynthetic organisms endowed with nucleus, cell wall, flagella and reserve substances.

Why is it dangerous to have too much carbon dioxide in the atmosphere
Answer:
too much CO2 is toxic for humans to inhale. we rely on plants to absorb CO2 and produce O2. If they was a sudden extinction of all plants on earth, this would lead to a rise of CO2 which would reduce O2 air quality. (not good at all)

1. For generating healthy cells to form replacement organs like brains
2. for directing differentation to treat diabetes and arthritis
3. for testing for possible side effects of a new cancer medication
4. for curing heart disease by regenerating damaged heart tissue
I HEARD THAT 4 IS NOT CORRECT SO PICK THE CORRECT ONE THA ISNT FOUR. ITS FROM EDGE2020
Answer:
1. For generating healthy cells to form replacement organs like brains
Stem cells can be used for curing heart disease by regenerating damaged heart tissue. The correct option is 4.
What is stem cell?Stem cells are the raw materials of the body, the cells that give rise to all subsequent cells with specific responsibilities.
Under the right conditions, stem cells divide to establish more cells known as daughter cells in the body or in a laboratory.
Bone marrow stem cells, for example, may be able to generate bone or cardiac muscle cells.
This research has resulted in early-stage clinical trials to assess the effectiveness and safety of the product in humans.
Adult stem cells, for example, are currently being examined in people suffering from neurological or cardiovascular disease.
Thus, the correct option is 4.

Researchers wanted to do research because they thought normal cells spontaneously became cancerous cells.
What are Henrietta's cells?The first immortal human cells to be generated in culture were from Henrietta Lacks. They are also known as Henrietta's cells. They were crucial in the creation of the polio vaccine. In the early space flights, they went up to investigate what would happen to cells in weightlessness.
Her cells have since been employed in numerous significant scientific breakthroughs, such as cloning, gene mapping, and in vitro fertilization.

Answer: hope this helps!!
Explanation:
How is fission different from budding?
1) Binary fission: Single parent cell doubles its DNA, then divides into two cells. Usually occurs in bacteria. 2) Budding: Small growth on surface of parent breaks off, resulting in the formation of two individuals. Occurs in yeast and some animals (like the hydra below).
I. Plant cells are formed from fertile soil. II. Animal cells must function properly for an organism to be healthy. III.Cells make up the petals, stem, and leaves of a lily plant. IV. Bacteria are produced from other living bacteria. Which describes the statements that Schwann and Schleiden would make? Schwann would make Statement I and Schleiden would make Statement IV. Schwann would make Statement II and Schleiden would make Statement III. Schwann would make Statement III and Schleiden would make Statement II. Schwann would make Statement IV and Schleiden would make Statement I.
Answer:
Schwann would make statement II and Schleiden would make statement III
Explanation:
Schleiden, a German botanist and Schwann was a zoologist, both have found that the plants and animals are made up of cells, they both shared their research and observation with each other and made the conclusion that all living organisms are made up of cells.
As mentioned above Schleiden was a botanist so he must have concluded and described that all plant organs are made up of cells, similarly as zoologist he proposed that the cell must function properly in an organism.
Answer:
B- Schwann would make Statement II and Schleiden would make Statement III.
