Sketch and label a food-web that includes at least 6 different items. Make
sure to have the arrows show how energy flows from one trophic level to
the next.
Answer and Explanation:
Example of a food-web:
(1) Algae --> (2) Protozoas --> (3) Krill --> (4) Cephallopods --> (5) Medium sized dolphin --> (6) Large Dolphin
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one.
1) The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. In this example, the autotroph organisms are algae, that make use of sunlight and inorganic matter.
The next links are the consumers:
2) Herbivores are primary consumers and feed on producers. In this example, herbivore organisms are protozoan.
3) Krills are the secondary consumers and feed on protozoans.
4) Some species of cephalopods feed on krill, among other species.
5) Specialized Cetaceans such as the Risso´s dolphin, feed especially on cephalopods, as they lack upper teeth and they only have a few teeth in their jaws.
6) The killer whale is a big sized-dolphin and a very important predator. It feeds on many animals, and one of them is the Risso´s dolphin.
The equation shows cellular respiration. During cellular respiration, glucose combines with oxygen to form carbon dioxide, water, and ATP.
Answer:
The correct answer is "The energy is transferred to ATP".
Explanation:
The missing information of this question is:
C6H1206 + 602 / 6CO2 + 6H2O + ATP
What happens to the energy in the bonds in glucose?
The energy is transferred to oxygen.
The energy is transferred to carbon dioxide.
The energy is transferred to water.
The energy is transferred to ATP.
The correct answer is "The energy is transferred to ATP".
During cellular respiration, the cell produces energy from the oxidation of glucose and it stores it in the form of adenosine triphosphate (ATP). The terminal phosphate group of ATP is highly energetic, and the cells breaks down ATP to use its energy in diverse chemical reactions. For this reason ATP is known as the "energy currency" or "coin of the cell".
A nucleotide does not contain
a. a 5-carbon sugar.
b. an amino acid.
c. a nitrogen base.
d. a phosphate group.
Answer:
b.) an amino acid.
Explanation:
A nucleotide contains three things:
a 5-carbon sugar a nitrogenous basea phosphate groupSince amino acids are not on this list, the correct answer is b.
A nucleotide does not contain a amino acid.
What are nucleotides?Nucleotides are organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid and ribonucleic acid, both of which are essential biomolecules within all life-forms on Earth.
Moreover, a nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).
Therefore, DNA and RNA are polynucleotides, which contain a chain of nucleotides monomers with different nitrogenous bases. Nucleotides are essential for carrying out metabolic and physiological activities.

Explanation:
Analyze whether the tiger is at the same level and whether it obtains the same amount of energy in both the food chains.
Answer:
No, the tiger is not at the same level in the food chain.
Explanation:
There are two different food chains in this example: 1. Spinach --> goat --> human --> tiger 2. Spinach --> goat --> tiger.
In the first example, tiger is a tertiary consumer because it feed on secondary consumer that is human which feeds on primary consumer, while in the second example, the tiger is secondary consumer because it feeds on primary consumer that is goat which feeds on producer. In the food chain, there are different trophic levels are present such as producer, primary consumer, secondary consumer and tertiary consumer etc. Some animals act as both secondary and tertiary consumer. In these two examples, tiger act as both secondary and tertiary consumer.
What are the main causes of antimicrobial drug resistance?
Answer:
Anti-infection opposition grows normally in microscopic organisms. Be that as it may, our activities can expand obstruction creating and spreading. This can occur:
at the point when human and creature wellbeing experts over recommend anti-infection agents
at the point when individuals don't accept anti-infection agents as coordinated
because of poor cleanliness and an absence of disease avoidance and control for example not washing hands appropriately

Choose which way of evolution caused the FQ antibiotic resistance.
Answer:
Antibiotic resistance is an act of evolution via natural selection. The antibiotic action is an environmental pressure: those bacteria which have mutation allowing them to survive and re-produce
Explanation:
A variation in the properties of an organism over a period of time is called evolution.
Antibiotic resistance can transpire naturally or due to progression.
This type of endurance occurs so that the bacteria can persist and proliferate in the changed conditions.
Fluoroquinolones (FQ) modify the enzymes like DNA gyrase and topoisomerase IV.
The bacteria in order to survive from this antibiotic adapted mechanism so that the use of antibiotics would not hinder their reproduction mode and hence they will be able to survive.

Why would you expect equal numbers of guanine and cytosine in a molecule of DNA, but not necessarily in a molecule of RNA?
Answer:
DNA is double-stranded, so there must be equal numbers of C and G because they pair to each other on the complementary strands.
RNA is only single-stranded, so there can be any number of C and G. They don't pair to each other, because there's only one strand.
Equal numbers of guanine and cytosine would be expected in a molecule of DNA, but not RNA because:
DNA is double stranded with the first strand being a complimentary copy of the other. The two strands are also associated with each other by hydrogen bond.RNA is single strand.In the double strand DNA, Adenine always pair with Thymine while Guanine always pair with Cytosine. Hence the number of Adenine must be equal to that of Thymine while that of Guanine must be equal to Cytosine.
The single strandness of RNA means that it can contain an arbitrary amount of any of the bases without following a particular rule.

What happens in the condensation part of the water cycle?
Answer:
Condensation is the opposite of evaporation. It is when water molecules in the air, which are in gas form, cool and accumulate into liquid form. In the air, this is the formation of clouds and sometimes you can see condensation on your water bottle in the summer if it has a cold liquid inside. When the hotter water molecules in the air touch the bottle, it is cooled and shifts to its liquid form. When clouds accumulate enough water droplets, they become too heavy to stay in the air and fall to the earth as rain, snow, hail, etc.
