Answers
Answer:
In the adult organism, mitosis plays a role in cell replacement, wound healing and tumour formation. Mitosis, although a continuous process, is conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase and telophase.
Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.

2. Has enough mass to assume a nearly round shape,
3. Has not cleared the neighborhood around its orbit and is not a moon.
A galaxy has less mass than a moon and more mass than a planet.
True
False
Answers
Answer:
False, major false. A galaxy is a small portion of the entire universe... it contains plants, stars, asteroids, moons are insignificant compared to it. Also, pretty much all moons are larger than planets so that wouldn't even make sense.
Answer:
FALSEExplanation:
First off a galaxy is one of the largest things in space, besides things like galaxy clusters.
Second all planets have more mass than the moon. Since planets have more mass than a moon, it is impossible to have less mass than a moon but more than a planet.
Finally, a galaxy is made up of millions of planets and moons. So it does not make any sense nor is it even possible.

How might a plant cope with the fact that the Calvin cycle uses more ATP than NADPH, yet produces roughly the same amount of both energy intermediates in photosystems I and II? Group of answer choices Electron flow rate can be increased, increasing both ATP and NADPH production. Plants often increase the amount of NADP reductase, thereby increasing NADPH production to match ATP output. Increase the electrochemical gradient for H+ across the thylakoid membrane, producing more ATP but not NADPH. Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH. More pigment can be rapidly created for greater photosynthetic capacity, producing equal amounts of ATP and NADPH.
Answers
Answer:
Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH.
Explanation:
A Calvin Cycle is defined as a process by which various plants and algae takes carbon dioxide from the air and turns it into sugar, the food which the food autotrophs needs to grow. The Calvin cycle is required for every living being on earth to survive.
Both the ATP and the NADPH are required by the Calvin cycle. It occurs in the chloroplast stroma of the plants. Calvin cycle uses more amount of ATP than the NADPH and produces roughly same amount of both the energies. Photosynthesis may revert from the noncyclic to the cyclic electron flow and it produces more ATP than NADPH.

¿Qué tipo de proceso metabólico se realiza cuando los lípidos y los fosfolípidos y triglicéridos se forman a ser moléculas sencillas dentro de la célula?
Answers
Answer:
catabólico
Explanation:
Los procesos metabólicos pueden ser:
Anabólicos: donde se forman moléculas más complejas a partir de moléculas simples. Esta formación de moléculas o estructuras más complejas consume energía. Catabólicos: donde se degradan o descomponen moléculas grandes o más complejas en otras más simples. Este proceso libera energía, que es utilizada en otros procesos y reacciones.En base a esto, la formación de moléculas sencillas a partir de moléculas grandes como los lípidos, fosfolípidos y triglicéridos es es proceso catabólico. En esta descomposición se produce energía para ser usada en otras reacciones.

How does a fire help grasslands?
Choose all that apply
Answers
Answer:
In most grassland ecosystems, fire is the primary mode of decomposition
Explanation:
Grasslands burn more readily than forest and shrub ecosystems, with the fire moving through the stems and leaves of herbaceous plants and only lightly heating the underlying soil, even in cases of high intensity. In most grassland ecosystems, fire is the primary mode of decomposition, making it crucial in the recycling of nutrients. In some grassland systems, fire only became the primary mode of decomposition after the disappearance of large migratory herds of browsing or grazing megafauna driven by predator pressure. In the absence of functional communities of large migratory herds of herbivorous megafauna and attendant predators, overuse of fire to maintain grassland ecosystems may lead to excessive oxidation, loss of carbon, and desertification in susceptible climates. Some grassland ecosystems respond poorly to fire.
A fire helps grasslands through the following:
Keeps trees from overtaking the grasses.Preserve biodiversity.What is Fire?This is the visible aspect of combustion of fuel and other materials to produce heat and flame.
controlled burning increases biodiversity by increasing spatial and temporal variation and helps prevent trees from overtaking grasses.

When energy is added to a wave, how can the wave change? Select all that apply
Answers
Explanation:
The amplitude can increase The frequency can increase Deceased wavelengthWhen energy is added to a wave, the wave changes with the following:
The frequency can increase.The wavelength can decrease.The amplitude can increase. What do you mean by Energy?Energy may be defined as the ability to do work. It is applied to an object to increase its velocity. It is something that defines how things change and move.
Frequency is inversely related to the wavelength and directly related to the amplitude. So, if frequency increases, the amplitude is also increased, but the wavelength decreases.
Frequency is defined as the number of peaks formed by the wave in 1 second.
Therefore, when energy is added to a wave, frequency and amplitude increase, while wavelength decrease.

Chemical manufacturing, such as the production of ethanol, acetone, organic acids, enzymes, and perfumes. Pharmaceuticals, such as the manufacture of antibiotics, vaccines, and steroids. Energy, in the form of biogas (methane)
2 Despite the fact that we have gobs of prokaryotic cells living inside and on us, humans are still categorically eukaryotic organisms. This means that all human cells—including those found in the brain, the heart, the muscles, and so on—are also eukaryotic.
