Answers
Answer:
Explanation:
If we break down the word autotroph, auto means “self” and troph means "feeding" or nourishment. However, when we break the word heterotroph, we get hetero- meaning other, and troph meaning feeders.
This is the critical difference between these two groups. Autotrophs synthesize or make their own food whereas, heterotrophs cannot make their own food thus have to rely on others by eating or absorbing others. For example, plants are autotrophs because they can make their own food using photosynthesis, whereas, humans are heterotrophs because we have to eat others to survive.
Answer:
autotrophs are organisms that can produce their own food from the substances around them using light or chemical energy
heterotrophs cannot synthesize their own food and rely on other organisms plants and animals for nutrition

What are carbohydrates?
A carbohydrate is defined as a bio-molecule which consists of carbon,hydrogen and oxygen atoms which are usually in the ratio of 2:1 with the empirical formula C[tex]_n[/tex](H₂O)[tex]_n[/tex].
This term is most commonly used in biochemistry as a synonym of saccharide which is a group of sugars, starch and cellulose.
They perform various functions in living organisms. They serve as an energy source and as well as structural components . They are a key component in providing nutrition and are found in wide variety of natural as well as processed foods.
Carbohydrates occur as cellulose in the cell walls of plants and is one of the components of insoluble dietary fibers.

A scientist studies the DNA in corresponding genes of a platypus, a
beaver, and a duck. The DNA from which two species are most likely to be most
similar? Explain your answer.
Answers
Answer:
platypus and a duck has similar DNA.
Explanation:
There are certain similarities which are present between duck and platypus such as structure of beak or mouth, webbed feet and laying eggs in order to continue its generation. These three characteristic make the platypus and duck similar to each other. There is also one major difference is present which is that the platypus is the only mammal which lay eggs and feed baby with their own milk. Its tail structure is also different from duck.
The DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.
Sequence homo-logy refers to the level of similarity between nucleotide (DNA) sequences due to shared ancestry in the evolutionary history of life.The species that share a more recent ancestor exhibit a higher level of sequence homo-logy than unrelated species.In this case, the linear order of nucleotides in DNA from platypus and beaver are most likely to be most similar because they are mammals, while ducks are birds.In conclusion, the DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.

Based on the information in the graph, explain what physical process causes the cell to change size.
Answers
Answer:
Osmosis
Explanation:
Osmosis is the process in which solvent molecules move from lower to higher concentration through a semipermeable membrane.
When a cell is placed in a hypertonic solution, the cell loses water and moves from higher concentration to lower concentration that is from inside the cell to the water solution and causes shrinking of cell.
Shrinking of cell means decrease in size of the cell along with the passing time and cell loses all its water.
Hence, the correct answer is osmosis.

Answers
Answer:
The atmospheric temperature decreases when snow starts melting because the snow absorbs thermal energy from the atmosphere to melt.
Explanation:
The temperature of the air, the intensity of the sun, the speed of the wind, and the amount of humidity are the factors that influence the melting of the snow. The thermal energy in the atmosphere is absorbed by the snow because the temperature of snow is less than the temperature of the atmosphere. When the flow of temperature takes place, the energy also flows. The thermal energy helps the snow to melt because the snow requires warmth to melt.

if a disease killed all the seagulls what effect would this have on the food web?
Answers
Answer:
if the disease kills all the seaguells then it will affect the food chain negativleyy because the population of the species that would eat them (predator) will decrease dramatically and the fish ( what the seaguells eat ) there peopulation will increase dramatically because they are not being eaten .
Explanation:
hope this helps , sorry middle school was a long time ago for me : )
Answer and explanation: it would mean that there would be an increase of fish which is what seaguls eat but a decrease of, for example, leopard seals because if there aren't enough seagulls the leopard seals would die of starvation which would then again decrease another animal species because there aren't enough leopard seals. This would then repeat itself again and again.
BIOLOGY EXPERTS!!!! Shared core processes support the relatedness of all eukaryotes. Discuss how chromosome structure and function provides insights into the history of life on Earth.
Answers
Answer: Many eukaryotic organisms are related based on the shared core characteristics and processes.
Explanation:
The following are the shared core processes shared by all eukaryotes.:
1. Cytoskeleton: It is a network of structural proteins, that helps in movement of cell and organelle support.
2. Membrane-bound organelle: Mitochondria and chloroplast are organelles that formed via endosymbiosis these are present in all eukaryotic organisms.
The DNA is the basic genetic material that is found in almost majority of living beings on earth. The DNA is being transmitted from the primitive organisms on earth to the modern day organisms. The chromosomes are the carriers of DNA. These chromosomes are passed from the parents to the offsprings through reproduction.

Answers
Answer:
Due to the movement of surounding water ijnto the cell.
Explanation:
A red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.
Osmosis is the movement of water that diffuses from a higher water concentration area to a lower water concentration area.
The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic to the red blood cell.The red blood cell will gain water, swell ad then burst.Thus, a red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.

When are two populations likely to have very similar allele frequencies?
A. If the selective pressures are different
B. If there is a high mutation rate
C. If there is a large amount of genetic drift
D. If there is a large amount of gene flow
Answers
Answer:
c). If there was a large amount of genetic drift.
If the price of gene drift is excessive enough, then two populations will have equivalent allele frequencies and consequently can be taken into consideration as a single powerful population.
What causes allele frequencies to live equally?Allele frequencies continue to be constant over the years due to the following: there is no considerable price of a brand new mutation. individuals with all genotypes are similarly able to mate and pass on their genes; that is, there's no choice against any precise genotype.
What are two impacts of allele frequencies of a population?The natural choice, genetic drift, and gene go with the flow are the mechanisms that purpose modifications in allele frequencies through the years. while one or greater of those forces are appearing in a populace, the populace violates the Hardy-Weinberg assumptions, and evolution occurs.
