What kind of genetic factors affect algae growth?
ANSWER :
Algae prefer stable conditions. Low water levels create slower, more uniform conditions that encourage algae growth. Warmer water leads to increased algae growth. The temperature of the water may even favor the growth of certain types of algae over others. Nutrients, like nitrogen and phosphorus, fuel algae growth; however, excess nutrients from human activities can exacerbate algae blooms.Which of the following did you include in your

In photosynthesis, plants use _______ and release ________. *
A. carbon dioxide, oxygen
B. oxygen, carbon dioxide
Answer:
A. carbon dioxide, oxygen
Explanation:
Photosynthesis is a process that certain organisms (plants, algae and some bacteria) undergo to produce their own food. The equation for photosynthesis is:
water + carbon dioxide + light energy —> glucose + oxygen
In photosynthesis, the plant takes water, carbon dioxide and light energy from the sun and turns it into glucose (sugar, or the food) and oxygen.
Therefore, the correct answer is A. carbon dioxide, oxygen. The plant will use carbon dioxide and then release oxygen as a waste product.

b. more wheat and less canola grown as crops
c. greater threat to forests from insect pests
d. greater biodiversity of wetland species
e. better agricultural conditions in northern Alberta
f. improved air quality in urban areas
thanks!
Answer:
a. more stable weather conditions --- NE
b. more wheat and less canola grown as crops ---E
c. greater threat to forests from insect pests ----E
d. greater biodiversity of wetland species ----E
e. better agricultural conditions in northern Alberta ----E
f. improved air quality in urban areas-----NE
Explanation:
The climate of Alberto change with the increase in temperature which disturb the weather condition of the region. This increase in temperature decreases the production of wheat crop so more wheat crop is cultivated for fulfilling the needs. This increase in temperature make the environment more suitable for different organisms. The climate is cold during winter so increase in temperature causes condition suitable for agriculture in northern Alberta. Improved air quality in urban areas is not possible due to more production of carbondioxide gas which leads to increase in temperature.

how has paraquat stopped the algae from making atp nadph and sugars
Answer:
This is by disrupting the mechanisms of photosynthesis.Paraquat is an herbicide. A photosynthesis inhibiting herbicides. In the light dependent reaction, It acts as oxidizing agent by accepting electrons from Photo system I. and lose these electrons to oxygen molecules which becomes oxidized.
Therefore, disrupting the electron transport chain.With the electron transport chain disrupted, PMF is inhibited, electrochemical gradients for generating energy for ATPs synthesis, by ATPase synthase enzyme is blocked.
Therefore, ATPs synthesis is prevented. With this, Calvin Cycle is blocked, so no CHO id formed. With lack of electron transport chain, NADPH will not be formed. .

Which do you think is better for the environment: paper or plastic
Answer:
I think it is plastic
Explanation:
even though it take 400 years for a paper bag to decompose, people use more plastic.
Answer:
Paper is better for environment
Explanation:
Paper is because it decomposes much more quickly than plastic, and because of that it is less likely to be a source of danger and will not pose a risk to wildlife. Paper is also more recyclable, while plastic can take between 400 and 1,000 years to decompose.

A student is given five samples and told they are lysine (an amino acid), lactose (a disaccharide), insulin (a protein hormone), RNA and fat. The samples are in test tubes marked 1-5, but the student doesn't know which compound is in which tube. The student is instructed to identify the contents of each tube. Base on these data, identify what is in each tube. In her first test, she tries to hydrolyze a portion of the contents of each tube. Hydrolysis occurs in all tubes except tube 3. In the next test, she finds that tubes 1, 2, and 3 are positive for nitrogen but only tube 2 gives a positive result for the presence of sulfur. In the next test the student shows that the compound in tube 1 contains a high percentage of phosphate. In the final test the student shows that compound 5 is hydrophobic. Base on these data, identify what is in each tube. 1 2 3 4 5 A. lactose B. RNA C. lysine D. fat
Answer:
1. RNA 2. Insulin 3. Lysine 4. Lactose 5. Fat
Explanation:
RNA contains both nitrogen and phosphate hence it is the substance in tube 1.
Insulin being a protein contains sulfur hence it is the substance in tube 2.
Lysine does not hydrolyse hence it is the substance in tube 3.
Fat is hydrophobic hence it is the substance in tube 5.
Since lactose does hydrolyse and because the rest have been identified, it must be the substance in tube 4.
Based on these data, each tube is identified as:
tube 1: RNAtube 2: Insulintube 3: Lysinetube 4: Lactosetube 5: Fat1. first testHydrolysis doesn't occur in lysine so, the 3rd tube contains lysine.
2. second testNitrogen is present in Insulin(in amino acids), RNA(in nucleotides), and Lysine. Insulin consists of two polypeptide chains (A and B) which are joined by sulfur bonds. So, 2nd tube contains insulin.
3. third testIn RNA, nucleotides are present which consists of phosphate groups. Adjacent nucleotides are joined together by phosphodiester bonds. So, 1st tube contains RNA
5. 4th testFatty acids are Hydrophobic due to the presence of long hydrocarbon chains. So, 5th tube contains Fat.

Consider these three scientific statements
1. The inherited traits of plant, animal, and microbial populations change through time because of differential reproductive success patterns, which are influenced by the way individual organisms interact with their environment.
2. If a certain culture of bacteria is subjected to more ultraviolet radiation than another culture, Then it's reproductive success rate will be reduced.
3. In sexual reproduction, Recessive alleles are always masked by dominant alleles. in other words, the traits of a Recessive allele will not be expressed if a dominant allele is present.
These statements have a lot in common. Each statement is testable, each describes a potential realishionship between observable factors, and each deals with a different aspect of reproduction or inheritance. However, one of the statements is typical of a scientific hypothesis, one is typical of a scientific theory, and one is typical of a scientific law.
Which statement is a hypothesis, which is a theory, and which is a law? "Justify your anwsers"
Answer: 1. Scientific theory
2. Scientific hypothesis
3. Scientific law
Explanation:
The scientific theory can be defined as the aspects of the natural world that are tested and proofed by the scientific methods, involving the observations, measurements and evaluation of the outcome. The scientific theory can be changed with new ideas or evidences. The first statement is a scientific theory because the microbial population may change due to the fact that how microbes interact rather than restricting to the differential reproductive success.
The scientific hypothesis can be defined as the statement that is required to be tested or verified by scientific method. It is based on presumption. The second statement is the example of scientific hypothesis because it is beginning with "if" here it is presumed that if the culture is exposed to ultraviolet radiation then reproductive success rate will be reduced.
The scientific law is based upon facts or evidences obtain after experimental trails or applying the scientific methodology. This cannot be changed with time. The third statement is the Mendel's law of dominance.
