Resource partitioning reduces the number of species that can share a given resource.
True
False
Answer:
true
Explanation:
When two species compete with one another for the same resource, their niches overlap. Resource partitioning reduces the number of species that can share a given resource. Some bats prey on certain moths, hunting them using echolocation. i.e. bats, have evolved to change the frequency they use for echolocation.
How does independent assortment increase genetic variation in Meiosis?
Answer:
Independent assortment produce new combinations of alleles.
Explanation:
In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. It results in gametes that have unique combinations of chromosomes.

which source of calories causes the body to expend the most energy during digestion?
The consumption of energy during digestion is known as the thermic effect of food.
Consuming food is how we get the energy needed to sustain the basic functions of our organisms. Digesting this food, however, also takes up energy. In fact, about 10% of the energy we expend daily is allocated towards the digestion and storage of food and nutrients. This is known as the thermic effect of food.
On average, the food with the highest thermic effect is that of vegetables and fruit with high water compositions. This, however, falls a bit out of the scope of the question given that these foods are often very low in calories. The food that is high in calories and has a high thermic effect is protein. On average, proteins consume 20-30% more energy to digest than other sources of calories.

Which of the following statements accurately describes the relationship between photosynthesis and cellular respiration?
The function of photosynthesis is to use solar energy to make ATP; the primary function of respiration is to break down ATP to release energy.
Photosynthesis only occurs in heterotrophs, while cellular respiration only occurs in autotrophs.
Photosynthesis and cellular respiration occur in separate, specialized organelles, and the two processes cannot occur in the same cell at the same time.
Photosynthesis uses solar energy to create organic molecules; cellular respiration breaks down organic molecules to make ATP.

Describe the activities of DNA and the three types of RNA.
Answer:
There are three types of RNA: mRNA, tRNA, and rRNA. mRNA is the intermediary between the nucleus, where the DNA lives, and the cytoplasm, where proteins are made. rRNA and tRNA are involved in protein synthesis. Additional RNAs are involved in gene regulation and mRNA degradation.
Explanation:
If you stained both onion epidermal cells and cheek epithelial cells with methylene blue which would stain more quickly and why?
Answer:
the nucleus at the central part of the cheek cell contains DNA. When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope. And methylene blue stains negatively charged molecules in the cell, including DNA and RNA. This dye is toxic when ingested and it causes irritation when in contact with the skin and eyes. The cells seen are squamous epithelial cells from the outer epithelial layer of the mouth.

Explanation:
can anyone writet about describing ● History of Ribosomes.
Answer:
The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells. In 1955, George E. Palade discovered ribosomes and described them as small particles in the cytoplasm that preferentially associated with the endoplasmic reticulum membrane. Along with other scientists, Palade discovered that ribosomes performed protein synthesis in cells, and he was awarded the Nobel Prize in 1974 for his work.
Each ribosome has a large component and a small component that together form a single unit composed of several ribosomal RNA molecules and dozens of proteins. The ribosome is responsible for translating encoded messages from messenger RNA molecules to synthesize proteins from amino acids. The ribosome translates each codon, or set of three nucleotides, of the mRNA template and matches it with the appropriate amino acid in a process called translation. The amino acid is provided by a transfer RNA (tRNA) molecule. Each newly translated amino acid is then added to the growing protein chain until the ribosome completes the process of protein synthesis.

Everything including you and me is made up of matter
True or False
Answer:
Technically, yes.
Explanation:
Depends on your point of view.
NOTE: This excludes light, and photonic interaction. That technically doesn't make up anything, because it has no mass.
Matter is anything that has mass and takes up space. Due to E=MC*2, energy and mass are relative, even though a small amount of mass, has a large amount of energy. So let’s backtrack. Matter is anything. Matter is energy. Matter is nothing? What about in an atom. Or in the vacuum of space? In an atom, between the nucleus, and the electron cloud, there is empty space. In the vacuum of space, most people think there is nothing. Just emptiness, until the next star, or the next planet. That is 100% wrong. I guess they are either thinking too hard or not enough. The vacuum of space actually has energy. Just a small amount of it. It takes up space, that check’s off. It has mass (excluding photons), that check’s off. And yes, it has energy. SO, since energy and matter are interchangeable, everything is made of energy, even though not everything is made of matter. Certain types of energy, sound, heat, light, are not made of energy. Does that mean that photons are not made of Matter? Well, sort of. They have no mass, so technically not, but they do have space and exert a force, which is also mysterious. So, I hope this confused you a little bit, with matter being energy, but not energy being matter. Here is something to spark the imagination: Is fire a solid, a liquid, or a gas
