Explanation:
Depth of Water (meters) Dissolved Oxygen (mg O2 per liter) Amount of Algae/sq. meter (kilogram) 1 9.2 550 5 9.0 535 10 8.5 404 15 7.0 155 20 5.5 45 25 4.2 12 Consider the data regarding the growth of algae in a large lake, like the one illustrated above. Plants release oxygen as a by-product of photosynthesis. Draw a conclusion about other life forms in the lake, based on this data. A) All of the life forms in the lake can be found within the top 10 feet of water. B) As you increase in depth of water, plant density decreases while fish density increases. C) Organisms in the lake rely on dissolved oxygen to survive. The lower the dissolved oxygen, the lower the survival rate. D) Plant survival is related to the amount of light (depth) but animal survival is related to the amount of oxygen available. The lower the amount of dissolved oxygen, the less animal life present in the lake.
Algae growth produces a high concentration of oxygen on the surface, which decreases with depth. The less oxygen available in deeper strata, the fewer surviving forms of life. The correct option is C.
-----------------------------------------------------------------------------------------------------------
Available data:
Depth of Water Dissolved Oxygen Amount of Algae/sq. meter
(meters) (mg O₂ per liter) (kilogram)
1 9.2 550
5 9.0 535
10 8.5 404
15 7.0 155
20 5.5 45
25 4.2 12
According to this table,
On the surface, there is a higher amount of algae, and hence, more dissolved oxygen. As it gets deeper, algae amount decreases as well as dissolved oxygen.
If oxygen decreases with depth, it suggests that plants -oxygen producers- lack, probably due to the lack of sunlight reaching the bottom.
Other forms of life
Algae growth on the surface blocks the pass of light to the deeper strata.The lack of light in deeper strata affects plants' growth.If there are no plants in deeper areas, there is no dissolved oxygen.Since animals need oxygen, they probably can not survive in deep regions.With no oxygen, the bottom turns into an anaerobic environment, in which anaerobic bacteria can survive.
These conditions can be related to eutrophication.
Eutrophication is a biological process produced in water by an oversupply of nutrients or organic matter.
This oversupply, mainly of nitrogen or phosphorous, favors phytoplankton multiplication, especially cyanobacteria.
Cyanobacteria overgrowth leads to an enhance in primary productivity and reduces the pass of radiation to deeper strata. This fact affects biota in deeper zones.
Gradually sedimentation begins, caused by the death of some vegetable organisms that sink in the bottom.
These sediments suffer decomposition in the absence of oxygen. Anaerobic bacteria act and produce fermentation.
Phytoplankton overgrowth on the surface and fermentation process in the bottom, originate toxic compounds that can damage the animals in the water body.
Animals die, creating more sediments in the bottom where there are anaerobic conditions.
The continued increase in decomposition and fermentation produces a bad smell and toxicity.
The result of eutrophication is the stratification of the water mass:
First superficial layer, the overgrowth of blue-green algae, produces toxins and interrupts the pass of light to deeper areas. The surface then becomes warmer. The second layer might have oxygen available for the animals. In the third layer, there is no oxygen, so life is impossible for animals or plants. In the fourth layer, there are animals and plant remains in the process of sedimentation. At the bottom, there are organic matter and anaerobic bacteria in charge of decomposition and fermentation, through which they produce toxic gases and smell.Options:
A) All of the life forms in the lake can be found within the top 10 feet of water. FALSE. Depends on the conditions and the species.
B) As you increase in depth of water, plant density decreases while fish density increases. FALSE. Plant and animals density decrease, as available oxygen decrease.
C) Organisms in the lake rely on dissolved oxygen to survive. The lower the dissolved oxygen, the lower the survival rate. TRUE.
D) Plant survival is related to the amount of light (depth) but animal survival is related to the amount of oxygen available. The lower the amount of dissolved oxygen, the less animal life is present in the lake. FALSE. Light does not reach the bottom, so there are no plants there. Plants also depend on oxygen, not only animals.

Single celled eukaryotes are considered some of the most complex
cells on earth. Why would scientists believe that single celled
organisms(eukaryotes) are more complex than multi celled
organisms?
Answer:
Eukaryotic cells are more complex than prokaryotes, and the DNA is linear and found within a nucleus. Eukaryotic cells boast their own personal "power plants", called mitochondria.The complex eukaryotic cell ushered in a whole new era for life on Earth, because these cells evolved into multicellular organisms.
Explanation:
Answer:
The ability to maintain different environments inside a single cell allows eukaryotic cells to carry out complex metabolic reactions that prokaryotes cannot. In fact, it's a big part of the reason why eukaryotic cells can grow to be many times larger than prokaryotic ones.
:-
One theory that may explain how eukaryotes became so complex is the endosymbiotic theory. This theory proposes that organelles like mitochondria and chloroplasts were once free-living prokaryotic cells that began to live within a larger host cell.
explain the effect enzymes have on chemical reactions
Answer:
Enzymes decrease the activation energy, Enzymes increase the rate of the reaction, Enzymes provide a site where reactants can be brought together.
Enzymes are like catalysts which enhance the rate of reaction by lowering the activation energy.
All the biochemical reactions are slow because of transition state barriers. These transition state barriers are an intermediate state before the formation of products. Transition state is a high energy state and it requires a lot of energy to cross this state but we can not produce this much energy in our body. That is why an enzyme is must to catalyze any bio-chemical reaction because enzyme provides an alternate pathway which requires very low energy to proceed.
Enzymes have certain active sites wherein substrates fit in and interact with each other with the help of their functional groups and interaction of these substrates subsequently leads to product formation.

What characteristic of water causes it to display adhesion cohesion high specific heat capillary action
I think the answer should be the fact that water is a polar molecule.
This means it will attract other molecules which are polar (adhesion), including itself (cohesion).
I'm not sure about the last part of the question (high specific heat capillary action, the wording is a little confusing), but I think the reason why water has a high specific heat is the hydrogen bonds. Hydrogen bonding is the strongest kind of bond you can have in a molecule, so it would be harder to break those bonds, even with high heat.

Which statement about the balanced equations for nuclear and chemical changes is correct? (1 point) Both are balanced according to the total mass before and after the change. A chemical equation is balanced according to mass number. A nuclear equation is balanced according to the total mass before and after the change. Both are balanced according to the mass number of each element before and after the change. A nuclear equation is balanced according to mass number. A chemical equation is balanced according to the total mass before and after the change.
Both nuclear and chemical equations are balanced according to the total mass before and after the change.
In every equation or reaction, the total mass of the reactants must be equal to the total mass of the products. In other words, all reactions - be they chemical or nuclear - must obey the law of conservation of mass.
The law of conservation of mass states that mass can neither be created nor destroyed, but can be converted from one form to another during a reaction.
Thus, in order to balance reactions involving chemical or nuclear reactants, the total mass before the reaction must be equal to the total mass after the reaction.

The two strands that make up the DNA double helix are said to be antiparallel. What does that mean?
Nucleotides containing adenine base pair with nucleotides containing thymine.
The 5' to 3' direction of one strand runs counter to the 5' to 3' direction of the other strand.
Base pairings create unequal spacing between the two DNA strands.
Answer:
The 5' to 3' direction of one strand runs counter to the 5' to the 3' direction of the other strand.
Explanation:
Antiparallel strands of a DNA molecule means that the phosphate groups at the start of two DNA strands are in opposite position (pole).
The DNA molecule is composed of two strands held together by hydrogen bonds. A single strand is different at its two ends. One end is called 5' (5 prime), the other is called 3' (3 prime). The names come from the notation for the two sugar carbon atoms which participate in the phosphodiester bonds. The different strands in the helix run in opposite (anti-parallel) directions. At each end of the double helix, one strand is 5' and the other is 3'.

what contributes to antigenic shift in influenza viruses?
Answer:
The particular structure of the influenza virus genome and function of its viral proteins enable antigenic drift and antigenic shift.
Answer:
Between worldwide outbreaks, known as pandemics, influenza viruses undergo constant, rapid evolution (a process called antigenic drift ), which is driven by mutations in the genes encoding antigen proteins.
Antigenic shift is the process by which two or more different strains of a virus, or strains of two or more different viruses, combine to form a new subtype having a mixture of the surface antigens of the two or more original strains. The term is often applied specifically to influenza, as that is the best-known example, but the process is also known to occur with other viruses, such as visna virus in sheep. Antigenic shift is a specific case of reassortment or viral shift that confers a phenotypic change.
