Answer:
The correct answer is - a decrease in nitrogen compounds available to organisms.
Explanation:
Nitrogen fixation is the process that involves the atmospheric nitrogen and converts into a nitrogen compound that can easily be consumed by the organism as nitrogen is one of an essential part of life.
Nitrogen fixation is carried out by the microorganism like nitrogen-fixing bacteria like azotobactor. If these bacteria were destroyed then there will be a decrease in the nitrogen compounds that are consumed by the organism as there is no more nitrogen fixation takes place.

Kierra is trying to decide which brand of lettuce seeds she would like to use in her garden this summer. After researching, she picked the two best-known brands to test. She decides to test them by planting one of each seed in a small space in her yard; her observations will be recorded so she can compare. What is the best reason why Kierra should consider planting more than one seed from each brand? A) She has enough room in her yard to grow more. B) Growing lettuce does not require much maintenance. C) She will have more data from each brand to compare. D) The soil and sunlight in her yard may not be best for lettuce.
Answer:
C) She will have more data from each brand to compare.
Explanation:
Kierra should consider planting more than one seed from each brand as it will help her to get more data from each brand to compare.
It will be helpful for Kierra to planting more than one seed because if she will plant one seed from each brand then there are chances that the plant might not grow or met some other nutritional defects. But if she plants more than one seed, there are more chances of plants to grow even if some seeds might fail to grow and that will help her with more data from each brand to compare.
Comparison is more accurate when there are more than one aspects given so, more seed would give more accurate data for comparison.
Hence, the correct answer is "C) She will have more data from each brand to compare."

If you would have to design a new drug to inhibit adipogenesis to fight obesity. How would you do it
Answer:
by inhibiting cell-cycle regulators involved in adipogenesis
Explanation:
Adipocytes are cells composed of adipose tissue and are specialized to store energy in the form of fat. In cell lines, it has been shown that adipogenesis can be inhibited through the use of inhibitory proteins, which function to arrest preadipocytes in the G1 phase of the cell cycle. These proteins are transcription factors that control cell-cycle progression by increasing gene expression of cell cycle inhibitors such as, for example, p21 protein. In the case of p21, this protein is a cyclin-dependent kinase inhibitor that binds and thus inhibits Cyclin-dependent kinases (CDKs), thereby controlling the progression of the cell cycle at the G1 and S phases.

Which statements about collagen molecules are correct?
1 Both types of secondary structure occur within the molecules
2 Large numbers of hydrogen bonds stabilize the molecule
3 repeated amino acid sequences determine the tertiary structure
A.1,2 and 3 B.1 and 2 only C.1 and 3 only D. 2 and 3 only
The statements which are correct about collagen molecules are that both types of secondary structure occur within the molecules and repeated amino acid sequences determine the tertiary structure.
Collagen is the main structural protein that is found in the extracellular matrix found in the body's various connective tissues. As the main component of a connective tissue, it is the most abundant protein which is found in mammals, making up from 25% to 35% of the whole-body protein content. Collagen consists of amino acids which are bound together to form a triple helix of elongated fibril known as a collagen helix. It is mostly found in connective tissue such as cartilage, bones, tendons, ligaments, and skin.
Thus the correct statements are 1 and 3 only.

How does Photosynthesis work? And what is the Photosynthesis equation?
Explanation:
photosynthesis the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
6CO2 + 12H2O + → C6H12O6 + 6O2 + 6H2O
Here, six molecules of carbon dioxide (CO2) combine with 12 molecules of water (H2O) using light energy. The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of breathable oxygen and water.
Answer:
The process of photosynthesis is commonly written as:
6CO2 + 6H2O → C6H12O6 + 6O2.
This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Suppose a few brown mice had a mutation that caused their fur to turn white in colder
temperatures. Would these mice be more or less likely to survive in this environment?
More
Less
Answer: More
Explanation: Assuming the environment is one of lighter colors like snow, the mice would be more likely to survive because their fur would help them camouflage into their surroundings. Thus, making them less susceptible to predator's.
The mutation in the colder temperature which causes their fur to turn white is more likely to help them in surviving better in this environment. Thus, the mutation is advantageous.
What are Mutations?A mutation is an alteration in the nucleic acid sequence such as DNA or RNA of the genome of an organism, such as the virus, or extrachromosomal DNA molecule which is present in the mitochondria and chloroplast of a eukaryotic cell. Viral genomes are the genomes which contain either DNA or RNA as their genetic material.
A mutation in a few brown mice had a mutation which caused the fur to turn white in colder temperatures. This mutation will increase the chances of survival of the organism as this help in camouflage. Camouflage is called as cryptic coloration, it is a defense or tactic which organisms use to disguise their appearance, usually the one which help to blend in with their surrounding environment.

A scientist found that a Petri dish from an experiment had not been cleaned several days earlier. In the dish, she discovered a bacterial culture that she had not seen during the experiment. How could she gather evidence to support a claim about whether the bacteria had developed from the material left from the earlier experiment? a)Take a sample of the bacteria and grow it in an incubator. b)Gather dirty Petri dishes from other labs to see if they grow the same bacteria. c)Check all the clean Petri dishes for residue from the previous experiment. D)Try the original experiment again, do not clean some of the Petri dishes, and see if the bacteria grow.
Answer:
D
Explanation:
The best way she can gather evidence to support a claim of the bacteria developing from the material left from the earlier experiment would be to repeat the original experiment again, leave some of the Petri-dishes uncleaned, and then see if the same bacteria would grow on the uncleaned Petri dishes.
If indeed the bacteria developed from the material left from the earlier experiment, the same bacteria should grow on the uncleaned Petri dishes in the second experiment. If they do not grow, it means that the source of the bacteria is from somewhere else within the lab.
The correct option is D.
Answer: D

Your lab uses the annelid worm Lumbriculus variegatus as a model organism to study regeneration. Your studies would be helped by knowing which genes are present in this organism, but its genome has not been sequenced. A recent technique for gene determination is RNA-Seq, in which RNAs are directly isolated and sequenced. What is a disadvantage of using RNA-Seq for gene identification?
a. RNA-Seq may miss genes transcribed in a very tissue- and temporal-limited fashion.
b. RNA-Seq relies on genes being homologous across species, but not all genes have homologs.
c. RNA-Seq works only in mammalian cells and therefore cannot be used with model organisms such as Lumbriculus or Drosophila.
d. RNA-Seq may selectively miss noncoding RNAs as compared to mRNAs.
Answer:
a. RNA-Seq may miss genes transcribed in a very tissue- and temporal-limited fashion.
Explanation:
RNA-Seq is a methodology used in molecular biology to identify RNA transcripts by using deep-sequencing techniques. RNA-Seq has shown that the genome is often transcribed in the form of non-coding RNA sequences such as, for example, long non-coding RNAs (lncRNAs), microRNAs (miRNAs), etc., thereby redefining our vision about transcription in eukaryotic organisms. This methodology is based on the conversion of RNAs to cloned cDNA (complementary DNA) fragments that are further sequenced to be mapped against the reference genome. In consequence, tissue-specific-transcripts are not detected by RNA-Seq in cells in which these sequences are not transcribed.
