Who said all animals were made of cells
Answer:
Theodor Schwann said all animals were made of cells.Explanation:
I hope l helped ❤❤❤It was proposed by Theodor Schwann that animals were made of cells.
Although Robert Hooke (who coined the term “cell”) first noticed them in 1695, it wasn’t until 1839 that Theodor Schwann (author of “The Theory of Cells”) and Mattias Schleiden first proposed the idea that all living things are made up of cells.
An animal cell is an eukaryotic cell with a plasma membrane surrounding it. The cell has a membrane-binding nucleus and a liquid cytoplasm and does not have a cell wall like a plant cell. Animal cells are part of the kingdom Animalia.
Theodor Schwann coined the term cell theory and claimed that all living things are made up of cells and that cells were the smallest and most fundamental component of all living things.

this is you're answer please give me thanks
Answer:
In cells, oxygen is needed for aerobic respiration, which allows for the extraction of energy from ingested foods. Thus supplemental oxygen at home and in hospitals is vital for those with breathing disorders such as emphysema.
Compressed oxygen tanks are used by mountaineers at high elevations to counteract the decreased O2 pressure at these altitudes.
Supplemental oxygen is needed for surgical patients intentionally rendered paralyzed for medical procedures, in which "heart-lung machines" keep their vital functions going.
Oxygen can be used as a sterilizing agent to kill certain anaerobic bacteria that are killed by sufficient exposure to the gas.
Industrial Uses of Oxygen:
Oxygen is needed for the reaction that converts carbon to carbon dioxide gas in steel working, which takes place under high temperatures in a blast furnace. The carbon dioxide produced allows for the reduction of iron oxides into more pure iron compounds.
Oxygen is used in other applications involving metal and requiring high temperatures, such as welding torches.
Aerospace Uses of Oxygen:
In liquid form, oxygen is used widely as an oxidizing agent for use in missiles and rockets, where it reacts with liquid hydrogen to produce the terrific thrust needed for take-off. Astronaut spacesuits include a nearly pure form of oxygen.
Oxygen is used to degrade hydrocarbon compounds, which are broken apart by heating them. This is used to create combustion that usually liberates water and carbon dioxide, but can also produce the hydrocarbons acetylene, propylene and ethylene.
Oxygen is used in sewage-treatment and water-purification plants. It is forced through water to increase the production of bacteria that metabolize waste products in the water.
Oxygen gas (O2) is needed to produce energy in things not linked to an electrical supply of their own, such as generators and vehicles (e.g., ships, airplanes and cars).

Use the library and other reference materials to research lupus. Then, write a 400-word report on what you have learned. Be sure to include symptoms, causes, and treatments.
Answer:
The one I chose is very interesting I think you will enjoy it.
Lupus is a multisystem disease in which autoantibody production can lead to inflammation and tissue
damage in any part of the body. The pathogenesis of lupus is thought to be a combination of
predisposing genetic factors and environmental factors such as medication, or infectious agents that
trigger an abnormal immune response. This occurs when Suppressor T cells fail to suppress, in other words there are defects in cell signaling

4. Discuss the sense organs of cnidarians
Answer:
To tell the truth I don't know what none of this stuff so I searched it up.
Explanation:
Cnidarian sense organs are thought to be exclusive to the medusa, a point we dispute subsequently. Nevertheless, the sense organs of the medusa are highly developed and distributed across Scyphozoa, Hydrozoa, and Cubazoa. In those hydrozoans with a medusa stage, many have eyes associated with the tentacle base.
Hope that is what you are looking for.
Answer:
he rhopalium, the sense organ bearing structure of Scyphozoa, as well as the Cubozoa (a modified group within the scyphozoans), contains the statocyst and eyes. It is borne on the margin of the bell in the medusa. The rhopalia of cubozoan medusae contain eyes with lenses, the most dramatic of cnidarian sense organs.

How can you use isobars to determine approximate wind speed and direction using the pressure map?
Answer:
Since variations in air pressure drive the winds on Earth, isobars also give meteorologists an easy way to assess wind direction and speed. Closely spaced isobars indicate large pressure changes over a small area, causing wind speeds to increase.

In what way do two alleles for the some trait differ?
A. The are found on different chromosomes.
B. They consist of different sequences of DNA
C. They are produced by two different people.
D. They are complementary.
Answer:
B. They consist of different sequences of DNA
Explanation:
Alleles are contrasting or alternative forms of a gene. A diploid organism i.e an organism with two sets of homologous chromosome, contains two alleles for each gene that encodes a trait. Although the two alleles of that particular gene encodes the same trait, they can encode different phenotypes i.e way it is expressed because they contain different sequences of DNA.
For example, in a gene coding for height in pea plants, two alleles, T and t are responsible. Allele T codes for tall height (phenotype) while allele t codes for short height (phenotype). Although the two alleles are for the same trait, they differ in the content of their DNA sequence, hence, are expressed differently or variably.
Why do most of the marine species live at or near the surface of the ocean

Which statement best describes how some trees respond to decreasing
temperatures and shorter days in the fall?
Answer: they drop their leaves and go into dormancy
Explanation:
Answer:
they drop their leaves and go into dormancy[
Explanation:
With a light-sensitive chemical, plants can sense the differences in day length. For example, in the fall, when the days start to get shorter, the trees sense that there is less sunlight. The plant is stimulated, and it sends messages telling the leaves to change colors and fall.
