Answer:
Debido a la presencia de partículas pesadas.
Explicación:
Debido a la presencia de carga positiva en el núcleo del átomo de Thomson, las partículas alfa α rebotaron cuando chocaron con el protón porque el protón es una partícula pesada y la presencia de neutrón la hace más pesada. Debido a la presencia de partículas pesadas en el núcleo, las partículas alfa no pueden atravesarlo. Solo puede pasar a través del átomo de Thomson donde hay un espacio vacío en el átomo.
A cell has 6 chromosomes. How many chromosomes will each daughter cell have if it undergoes mitosis
Answer:
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

Explanation:
what do you mean by photo synthesis?
Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.

When the particles are equally spaced apart they have reached:
A. Hypertonicity
B. Dynamic Equilibrium
C. Homeostasis
D. Osmolarity
Answer:
B. Dynamic Equilibrium
Explanation:
Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium". The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, the movement of molecules does not stop.
Answer:
B. Dynamic Equilibrium
Explanation:
When the particles are equally spaced apart they have reached the dynamic Equilibrium.
A toad is brought into a new ecosystem. It is stronger than the toads that
already live there and reproduces quickly. Which is the best way to describe
these toads in the new ecosystem?
A. Invasive species
B. Native species
C. Keystone species
D. Cyclical species
Answer:
a
Explanation:
newer, stronger, and reproduces more
this means that the other animals would have to compete and they usually lose.
Invasive species is the best way to describe toads in the new ecosystem. Therefore, option (A) is correct.
What are invasive species?Invasive species are non-native organisms that are introduced to an ecosystem and have negative impacts on the environment, economy, or human health. They typically outcompete native species, reproduce quickly, and lack natural predators in the new ecosystem.
The fact that the toad is stronger than the toads already living there and reproduces quickly suggests that it may outcompete native toads for resources and space. This could potentially lead to a decline in the population of native toads, which could have negative effects on the ecosystem.

2. Which of the following statements is true?
A Cells don't need nutrients.
B Chloroplasts contain a cell's
genetic material.
C Cells grow and reproduce.
D All nonliving things are made
of cells.
Answer: C. Cells grow and reproduce.
"All cells grow and reproduce. Eukaryotic cells reproduce through mitosis and meiosis, while prokaryotes reproduce through binary fission."
Explanation:
A. "Some essential nutrients are required for cellular function but cannot be produced by the animal body. These include vitamins, minerals, some fatty acids, and some amino acids. Food intake in more than necessary amounts is stored as glycogen in the liver and muscle cells, and in fat cells."
B. "Chloroplasts and mitochondria are subcellular bioenergetic organelles with their own genomes and genetic systems. DNA replication and transmission to daughter organelles produces cytoplasmic inheritance of characters associated with primary events in photosynthesis and respiration."
D. "Instead of cells, a non-living thing is made up of elements or compounds that form from chemical reactions. Examples of non-living things are rocks, water, and air."

ow do cells use food to make energy and maintain homeostasis
Answer:
Cells obtain energy through the process of cellular respiration. It is a metabolic process of conversion of the biochemical energy from the nutrients into adenosine triphosphate (ATP). ... They exchange substances with the new cells and also eliminate the wastes thereby maintaining homeostasis.
Explanation:
There are several ion transport mechanisms within the cell membrane that function to maintain proper levels of solutes inside and outside the cell. ... This system uses the energy stored in ATP to pump potassium into the cell and sodium out of the cell.
What are the chances that your patient’s son will inherit the Alzheimer gene? Refer to your punnet squares to?
which of the followimg could be reasons why popultion sizes may reach and maintaim plateaus? choose the three that apply
Will mark as brilliant answer
Answer:
Below :D
Explanation:
So basically, this question is asking what will cause a species' population to reach a point where it stops increasing.
Lets think about what can cause a lack of increase?
A decrease can cause this.
Or a slow in the rate of increase.
Now lets look at our selectable answers and see if any of them would fall under these two things.
First up is fewer deaths.
Well, fewer deaths basically means less of a decrease in population.
This is the opposite of decreasing the populatin count, and would instead raise it.
Next we have a limit in food supply.
This would cause a organism to starve and die.
So this would cause a decrease in population count.
So B is one of the answers
Next up is competition with other species.
When two species compete for a sort of resources, one massivly dies out due to outcompetion, and loses the resources needed to survive.
So this would also cause a large decrease in population count.
This makes C one of the answers
Next is increase in birth rates.
This would cause more organisms to be born of a species, basically increasing the population count.
This is the opposite of a decrease in population.
Next we have competition for space.
This is very similar to answer C, and the outcompeted species dies out due to lack of space.
So E is one of the answers
Now, the next answer seems viable, because major storms can kill off organisms, like hurricanes, earthquakes, and volcanos for instance.
However, as seen in many organisms over history, while these major storms kill of organisms, they can recover.
So although major storms decrease populations, they dont actually limit them.
In the end:
B is correct
C is correct
E is correct
Hope this helps!
