State one importance of photosynthesis
Answer:
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die.
Explanation:
Use the passage and the illustrations to directly answer questions 1-5 on the other side. Then you will apply the information to other successions in-order to answer questions 6-10.
The water level of Lake Michigan was once 18 meters higher than it is today. As the water level fell, land was exposed. Many small lakes or ponds were left behind where there were depressions in the land. Below are illustrations and descriptions of four ponds as they exist today.
Pond A: Cattails, bulrushes, and water lilies grow in the pond. These plants have their roots in the bottom of the pond, but they can reach above the surface of the water. This pond is an ideal habitat for the animals that must climb to the surface for oxygen. Aquatic insect larvae (food for larger insects, which in turn are food for crayfish, frogs, salamanders, and turtles) are abundant.
Pond B: Plankton growth is rich enough to support animals that entered when the pond was connected to the lake. Fish make nests on the sandy bottom. Mussels crawl over the bottom.
Pond C: Decayed bodies of plants and animals form a layer of humus over the bottom of the pond. Chara, branching green algae, covers the humus. Fish that build nests on the bare bottom have been replaced by those that lay their eggs on the Chara.
Pond D: The pond is so filled with vegetation that there are no longer any large areas of open water. Instead, the pond is filled with grasses. The water dries up during the summer months.
Questions:
Succession 1 – Drying of a Pond
1. Write the letters of the ponds in order from the youngest, to the oldest.
2. As the ponds undergo succession, what is happening to the type and number of organisms?
3. Black bass and bluegill make their nests on sandy bottoms. In which pond would you find them?
4. What will happen to the black bass and blue gill as the floor of the ponds fills with organic debris?
Answer:

Describe the function of sensory neurons. What do sensory neurons do in your body?
Answer:
Answer in explanation.
Explanation:
Sensory neurons are nerve cells that are triggered by sensory input from your surroundings. Let's say you touch a hot object with your fingers. This causes sensory neurons to activate and transmit messages to the rest of the nervous system about what they've discovered (which is that the object is hot).

In which process is rapid reproduction an advantage?
Explanation:
In fact many simple organisms benefit from rapid asexual reproduction in order to maintain a stable populations. They may not be as able to change or adapt to new threats, but can certainly out produce them. Or create enough offspring that beneficial mutations are bound to occur.
If a purple-flowered plant is crossed with a white-flowered plant, and 37% of the offspring have white flowers, then the genotype of the purple-flowered parent plant is:
Answer:
The difference between genotype and phenotype is that phenotype is the physical appearance of a trait and genotype is the genetic constitution underlying a trait.
circular dna not part of a bacterial genome is called a __.
Answer:
a plasmid
Explanation:
I think it's called a plasmid but I'm not sure. hope it helps
Circular dna not part of a bacterial genome is called a plasmid.
What is plasmid?
A plasmid is a small piece of extrachromosomal DNA that is contained within a cell. It is distinct from the DNA of the chromosomes and has the ability to multiply without help from the chromosomes. Plasmids are most frequently found in bacteria, where they take the form of small, circular, double-stranded DNA molecules. However, archaea and eukaryotic cells can also occasionally contain plasmids.
Plasmids are naturally found in the cells of bacteria, and they can also be found in the cells of some eukaryotic organisms. Plasmids are often responsible for conferring genetic benefits on bacteria, such as resistance to antibiotics, because the genes they carry.
Therefore,circular dna not part of a bacterial genome is called a plasmid.

Select all of the mechanisms that could have resulted in the evolution of various combinations of exons, giving rise to different genes.
Check All That Apply
exon loss
exon duplication
5' capping
mutations in the splicing mechanism
DNA mutations
tRNA shuffling
Given what we know about the mechanisms surrounding human DNA, we can confirm that the ones that may result in the evolution of various combinations of exons are:
Exon lossExon duplicationMutations in the splicing mechanismsDNA mutations.An exon is a segment of DNA that carries information for the formation of specific proteins, whereas an Intron, its counterpart, applies to the segments that do not carry information or code for any proteins.
Given its nature of carrying genetic information, the loss or duplication of exons can lead to various combinations of these. Exons are arranged in specific segments of the genetic code, the loss of one can cause the interaction of Exons that were not previously related, the same may happen with duplication.
Splicing is the mechanism by which introns are removed from DNA. Since introns do not code for anything, they can be removed without harm and the exons can be arranged to form mature messenger RNA. A mutation of this mechanism can cause Exons to be arranged in new formations.
Finally, much like the Splicing mechanism, mutations in the DNA can cause the recombination of exons by affecting the genetic code of the exons themselves.

how can you prove that arteries and veins in the heart function differently when compared to the rest of the body?
Answer:
Explanation:
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.
Answer:
Arteries are thicker and stretchier to be able to handle the higher pressure of blood moving through them. Veins are thinner and less stretchy. This structure helps veins move higher amounts of blood over a longer time than arteries.
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.

A moose eats a lily pad. The food the moose eats is used to make ATP energy that can be used in cellular processes. The products of photosynthesis are the reactants of cellular
respiration. What is included in D in the diagram above? Choose ALL that apply.
A) water
B) oxygen glucose
D) sunlight
E) carbon dioxide
Photosynthesis is a build up process that ensures the production of the by-products glucose and oxygen from carbon-dioxide and water in the presence of sunlight.
Since the products of photosynthesis are the reactants of cellular respiration, D would include oxygen, glucose and ATP (option B).
In cellular respiration in the mitochondrion from the diagram, glucose and oxygen is required and here also, the ATP derived from photosynthesis is also depleted in cellular respiration. As cellular respiration requires oxygen to give out carbon-dioxide and water.Learn more about cellular respiration: https://brainly.com/question/866852
Answer:
A) Oxygen and B) Glucose
Explanation:
Photosynthesis uses carbon dioxide and water to create oxygen and glucose, therefore we can eliminate E and A, since they aren't products of photosynthesis, they are only components that help in production. Since water and carbon dioxide create oxygen and glucose, that means that oxygen and glucose are both products of photosynthesis. We could also eliminate D, because sunlight is a part of photosynthesis, however plants do not produce sunlight, they only take in in. This leaves us with only A and B as our remaining answer choices, since we already know that the products of photosynthesis are the reactants of cellular respiration.
