Answer:
electrons, protons, neutrons
Explanation:
Answer:
Protons, Electrons, Neutrons
Explanation:
Protons and neutrons are in the center of the atom, making up the nucleus
and...
Electrons surround the nucleus (in cloud or ring form)
Protons: are positively charged
*Protons give the element its name, therefore if there is a change in protons then it is a new element
Electrons: are negatively charged
Neutrons: are neutral and not charged
*Protons and Neutrons give the atom its mass
*If the mass of the same element changes it is because of the neutrons and it called an isotope
There are many models to show you how an atom looks...
Plum Pudding Model, The Nuclear Model (I like to call it the jimmy neutron model because that's what the symbol looks like), Planetary Model, and Quantum Model
*The last two models (Planetary and Quantum) are used more in science class
*The Quantum Model (made by Erwin Schrodinger) is widely accepted and it is the most accurate model since 1926
*The Planetary Model (by Niels Bohr) is used in science class to help you see how electrons are on energy levels and how they move when they are " excited" or absorbs energy and when they lose energy

Strawberry cells are octoploid (each cell contains eight copies of chromosomes) whereas banana cells are triploid (each cell contains three copies of chromosomes). Which do you predict will yield a greater quantity of DNA—5 g of strawberry tissue or 5 g of banana tissue? Explain your reasoning.
Answer:
5 g of strawberry tissue
Explanation:
One would expect 5 g of strawberry tissue to yield a greater quantity of DNA because the cells of strawberry have 8 sets of each of the chromosomes in their genomes when compared to the cells of banana with just 3 sets of each of the chromosomes in their genomes. The more the ploidy level of a cell, the more the number of sets of each of the chromosome set and the more the amount of DNA in the cell.

Consider the diversity of living organisms on Earth and describe your thoughts on how meiosis might be responsible for that?
In the 18th century, Carl Linnaeus published a system for classifying living things, which has been developed into the modern
classification system. Recently the classification system of life was changed to include not five but six kingdoms, as well as
three domains. Earlier classification attempts were based mostly on structural features. Classification of many species, old and
new, continues to be hotly disputed as scientists find new information or interpret facts in new ways. Now, DNA technology
has allowed scientists to re-examine the relationships between organisms to refine the classification system.
One of the modern kingdoms contains organisms with a wide variety of characteristics, including: unicellular or multicellular,
autotrophs, ingestive heterotrophs, or absorptive heterotrophs, They can live in water, soil, and even living bodies. They are all
eukaryotes. Which kingdom is best described here?

Which ingredients are needed to transform NADP+ to NADPH?
an electron and two hydrogen ions
two electrons and two hydrogen ions
two electrons and a hydrogen ion
an electron and a hydrogen ion
Answer: Two electrons and a hydrogen ion
Explanation: The light reactions use solar power to reduce NADP+ to NADPH by adding a pair of electrons along with a hydrogen nucleus, or H The light reactions also generate ATP by powering the addition of a phosphate group to ADP, a process called photophosphorylation.
The ingredients needed to transform NADP+ to NADPH are an electron and a hydrogen ion.
Nicotinamide adenine dinucleotide phosphate ion (NADP+) is an energy carrying ion which transfers high energy electrons from chlorophyll to other molecules during photosynthesis.
Photosynthesis is defined as the process by which green plants are able to manufacture their own food.
In the light stage of photosynthesis, the electron and hydrogen atom released during photolysis of water is picked up by the energy carrying ion NADP+.
This is then converted to NADPH, that is Nicotinamide Adenine Dinucleotide Phosphate Hydrogen.

Cell organelles have different functions that help maintain homeostasis within the
cell. The processes of photosynthesis and cellular respiration depend on these
organelles working properly. Identify the letter of the organelle whose function is to
store water and dissolved salts?
The function of the vacuole is to maintain the turgid pressure that is to maintain the cell turgidity. It stores water along with the dissolved salts in it. The answer is option B.
What are the other parts that are present in the structure of vacuole ?There are various enzymes that are present in the vacuoles and it is just like the pool of the plant cell which stores the various enzymes along with the water molecules and the dissolved salts.
With its roles that perform or help in the plant cell function that are the central vacuole which stores salts, minerals as well as nutrients, along with proteins and pigments that helps in the plant growth and plays important structural kind of role for plant. The organelle that is the central vacuole of plant cells that helps it to just maintain the volume along with the structure.
Vacuoles store the materials like water along with salts and proteins as well as the carbohydrates. Most of the plant cells that are having a single or the large central vacuole. The function of them is that they just store the salts with the sugars with few type of proteins and even the plant colors. They are even working as the storage bags for cell.

Explanation:
An organelle is a structure inside the cell that preforms functions that are necessary for the cell.
Examples of organelles are the ER, the Golgi Apparatus, and the Mitochondria.
Hope this helps.
A structure within a cell that performs a specific function is an organelle. An organelle is a subcomponent of a cell.
What are cell organelles?Cell organelles are the ultrastructure's present in the cell and they show division of labor.
These organelles perform specific function for the cell and thus constitute the framework of all living organisms.
The basic structure of cell contains a plasma membrane, nucleus and cytoplasm. However, ultra-microscopic structures are embedded in the cell cytoplasm and they are designated as organelles in a cell.
Endoplasmic reticulum, Golgi apparatus, mitochondria, ribosomes, microtubules, lysosomes etc. are the specialized organelles present in cell.
Each of these organelles perform specific function. For instance, mitochondria help in energy production, Golgi helps in protein modification and packaging.
Cell organelles are thus important structural and functional elements of a cell.

You are a medical scientist who has been doing research on dialysis patients to better understand the
effect of different solutions on blood cells. You put a patient's blood cell in three mineral solutions: a
hypertonic, hypotonic, and isotonic solution. Make a prediction for how a blood cell will react in
each type of solution. Make sure your answer includes how different types of solute concentrations
affect water movement through a semi-permeable membrane.
Answer:
Hypertonic: cell with shrivel
Hypotonic: cell will lyse (expand)
Isotonic: cell with not change
Explanation:
Hypertonic has a higher concentration outside the cell so there will be a net flow of water out of the cell
Hypotonic has a lower concentration outside the cell so there will be a net flow of water into the cell
Isotonic is when the concentration is the same so there will be no net flow of water
An hypertonic solution has a higher concentration than the inside of the cell's cytoplasm, a hypotonic solution has a lower concentration that the cell's cytoplasm an isotonic solution has the same concentration as the cell's cytoplasm. When placed in a hypertonic solution the cell will lose water through osmosis and will shrink. When placed in a hypotonic solution the cell will absorb water through osmosis and it will increase in size untill it bursts. This proces is called cytosis. When placed in an isotonic solution the cell will keep it's initial size.
