What conclusion can be made if a positive test was the result for any of the organic molecules for the water sample? This a question from a assignment that has to do with a lab we did today.
Answer:
Because some effects will occur.
Explanation:
The positive test which was the result for the organic molecules for the water sample showed that there is some change occurs in water sample by adding of organic molecules due to which the results of the test comes positive. If there is no change occurs in the water sample by adding some organic molecules so the results will come negative which means no effect.

All plants and some algae have a complicated life cycle that includes both a multicellular diploid _______ stage and a multicellular haploid _______ stage. This type of life cycle is called _______.
Answer: sporophyte, gametophyte, alternation of generation
Explanation:
Alternation of generation is a kind of life cycle seen in plants and algae in which the diploid asexual and haploid sexual stages exist. A sporophyte is multicellular and diploid which is an asexual stage. It produces the haploid spores through meiosis. The haploid spores germinate to produce haploid gametophyte. The gametophyte produces gametes by the process of mitosis.

3. Lawrence, Kansas and Nashville, Tennessee occupy similar latitudes. Why is one found in a grassland and the other in a forest biome
Answer:
The distance between Lawrence, Kansas and Nashville, Tennessee is 501.74 miles. So they are really far apart.
The location of Lawrance, Kansas is:
Latitude: 38.9560 Longitude: -95.2520.
And for Nashville, Tennessee is:
Latitude: 36.174465, Longitude: -86.767960.
So while the Latitudes are similar, the longitudes are not, and this is why you can see that the geography of each place is different.
Glucose molecules from food sources provide energy to the cells of the human body. After a person eats, the level of glucose in their blood increases. If a person's blood glucose level becomes too high, a hormone in the pancreas, known as insulin, is released. Insulin helps move glucose out of the bloodstream. This causes the blood glucose level to decrease and return to equilibrium. The production of insulin is a mechanism that regulates the human body's internal environment and aids in
Answer:
regulating blood sugar levels
Explanation:
The primary function of the insulin hormone is to convert the excess glucose in the blood after a meal and store it for later. Glucose gets converted to glycogen, which is a compact molecule ideal for storage. When the body is need of energy, this glycogen is broken down to make up for the lack of glucose present in the blood.

In C3 plants the conservation of water promotes _____. In C3 plants the conservation of water promotes _____. photorespiration a shift to C4 photosynthesis photosynthesis the opening of stomata the light reactions
Answer:
The correct answer is "photorespiration".
Explanation:
Photorespiration is a process in plants, where molecular oxygen is taken in a light-dependent manner. Photorespiration is often considered a wasteful pathway because it competes with the Calvin cycle, which is much more efficient. In C3 plants the conservation of water promotes photorespiration. This occurs when the C3 plants close its stomata because the environment its too hot, or the carbon dioxide concentration drops to about 50 ppm.
A bacterium was found to contain a sequence of ATCGGGATCCT in its genome. A few generations later, the sequence was found to be ATCGGGGGGATCCT. What type of mutation caused this change in the bacteria?
Answer:
This question lacks options, the options are:
A) Deletion
B) Duplication
C) Inversion
D) Insertion
The correct answer is Insertion mutation
Explanation:
Mutation refers to changes that occur to the nucleotide sequence of a gene or DNA. Mutation produces different effect in the mutated organism and is classified based on how it occurs. Mutations can be deletion, insertion, duplication, inversion etc.
Based on the description of the mutation that occured to the bacterium sequence, it is an INSERTION MUTATION. An insertion mutation is a kind of mutation in which extra nucleotide bases are added to the original sequence. This is the case of this bacteria sequence, which was previously found to contain: ATCGGGATCCT.
After few generations, nucleotide bases "GGG" i.e three Guanine bases has been added to the sequence to give a mutated sequence: ATCGGGGGGATCCT.
Answer:
Duplication
Explanation:
Where should the biosphere label appear in the systems model? Use reasoning to explain your answer.
Answer:
Explanation:
Biosphere is the portions/regions of the earth (including land, sea and atmosphere) where living organisms exist. From the picture attached, it can be seen that there are living organisms in the hydrosphere (fishes), geosphere (plants) and anthrosphere (human). The entire system should have been labelled biosphere and not atmosphere.
NOTE: Atmosphere is an empty air space surrounding/around the earth (or other celestial body).

Compare the inputs and outputs of humans and robots in terms of matter and energy.
Answer:A robot is a machine. It is often, or almost always, automatic, which means that it is able to perform activities on its own without the aid of external variables, like humans. It moves in the way that it was originally programmed, or designed to act. These actions are described as ‘intents’ of its own. For example, a robot that is designed to play ping pong will really move like a ping pong player, compared to a robot that is just used for plain surgical operations.
‘Robot’ is also a word that refers to the sum of all the groups of robots, comprised of the physical robots and the virtual robots (as in software). In the case of the latter, these are called bots.
Human beings are also highly social individuals. They survive alongside other people in groups called communities or families. They are capable of forming relationships, and generating complex feelings, or emotions such as love.
1. Humans are organic beings, while robots are not.
2. Humans are far more complex and superior to robots in almost all aspects.
3. Humans are highly social beings compared to robots
