Answer:
Its Euglena
Explanation:
Shape change from normal elongated egg-shape to round-shape in stressful environment. These shape changes attain two transition phases. The I-transition phase is reversible where the organism can return to normal if favourable environment persists.
Why does water run through gravel quickly?
A.Gravel has a high porosity (lots of holes)
B.Gravel has a low porosity (few holes)
C.Gravel does not have a porosity which makes the water move quickly
Answer: I belive it is A
Explanation:
Gravel is not packet super tight like say dirt is. The small spaces between the tiny chunks of rock and mineral that are present in gravel allow water too smoothly slide in.
(10 points) Miller and Urey recreated Earth’s early in a test tube. Then they bombarded the chemical mixture with ultraviolet light and simulated lightning. What were the results?
Answer:
Cell membranes had formed
Explanation:
I hope it helped
The Miller and Urey experiment showed for the first time that the organic molecules necessary for life could be formed from inorganic components.
In 1953, scientists Stanley Miller and Harold Urey experimented to verify that organic molecules could form spontaneously under environmental conditions similar to those of the Earth in its early days.
To do this, they built a closed system in which they included a container with hot water and a mixture of gases that supposedly abounded in the Earth's atmosphere at the beginning. In addition, they devised the way to simulate lightning bolts that provided energy for chemical reactions in the atmosphere.
After running their experiment for a week, they resulted in the formation of various types of amino acids, sugars, lipids, and other organic molecules. This experiment allowed them to show that at least some of the structural units of these molecules could form spontaneously from simple compounds.

If Earth suddenly increased in mass, what might happen to its orbit around the Sun?
It says biology but it is just science
Answer:
If the orbit of the Earth changes, then the distance between the Earth and the Sun changes. If you tug on an object once (as you would, if you suddenly increased the mass of the sun), you'll likely pull a circular orbit into a more oval, looping orbit.

Explanation:
DNA replicates twice during meiosis
true or false?
Answer:
Meiosis consists of one round of DNA replication and two rounds of chromosome segregation.
Explanation:
DNA replicates twice during meiosis. Meiosis consists of one round of DNA replication and two rounds of chromosome segregation. Therefore, this statement in false.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.
Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). In humans, body (or somatic) cells are diploid.
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Explanation:
Decomposers (fungi, bacteria, invertebrates such as worms and insects) have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting.
Natural selection causes what to occur?
Answer:
Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. Natural selection depends on the environment and requires existing heritable variation in a group.
Hope this helped!! Have a great day!! :))
Explanation:
Answer:
(I'm not sure if this is what you mean) It causes reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual to occur.
Explanation:
If the four conditions (reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual) change, then a natural selection occurs.
The endosymbiotic theory states that eukaryotes evolved from prokaryotes. Which statement is part of the endosymbiotic
Note about the question:
Statements are missing, and I failed to find the complete question. So here I give you some details about the theory that will help you to indetify the correct statement.
Answer and Explanation:
The endosymbiotic theory essentially states that some organelles of the eukaryotic cells, such as mitochondria and chloroplasts, were once free-living bacteria. Probably, these organisms must have been phagocytosed but not digested by another cell. On the contrary, these bacteria were able to adapt to their host in such a way that the two cells established a dependent relationship with each other.
It is speculated that chloroplasts derivate from cyanobacteria and that mitochondria derivate from rickettsias.
Cells would be beneficiated from this new bond, at the point that they could not survive by themselves anymore.
This theory is supported by a few characteristics of the chloroplasts and mitochondria that suggest that they once were a free cell. For example,
Both organelles present their genetic material. This DNI is independent of the cell´s DNA, is bi-catenary and circular, identical to the bacterial DNA, and very different from the one of the eukaryotic cells. These organelles do not divide by mitosis. Instead, they do it by binary fission and are capable of synthesizing their ribosomes and organelles. Both organelles present a double membrane, a characteristic that reinforces the idea of being phagocyted. The internal membrane looks identical to the bacteria membrane, while the external membrane looks like the eukaryotic one. In fact, in this internal membrane are placed the energy centers, exactly as it occurs in bacterias membrane. Finally, the sizes of the organelles are similar to the size of some procaryotes.A teacher makes the analogy that stem cell research did for medicine what the Internet did for communication.

Cricketers chirp faster when the night is warmer is a testable hypothesis.
What is testable hypothesis?A hypothesis is a theory that attempts to explain or forecast the relationship between two or more variables.
A testable hypothesis is one that can be proven or refuted through experiments, data collection, or personal experience.
A tested hypothesis requires a relationship statement between two or more variables. All of the following terms should be included: "more than," "less than," "greater than," "different from," and "related to." It also needs to be justifiable and consistent with previous research findings.

In the Mitochondria, two ATP molecules are produced dotseveral other compounds are also created these compounds are capable of storing high slash energy electrons startthe compounds are fan changed into other forms that can carry the high-energy electrons to the next stage.. |Which word from the paragraph help this reader to understand the meaning of "produced"? |. 1. Storing
2.compounds
3.created
4.change.
Answer:
Electron transport chain
This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.The citric acid cycle is a series of chemical reactions that removes high-energy electrons and uses them in the electron transport chain to generate ATP. One molecule of ATP (or an equivalent) is produced per each turn of the cycle.
