what is the difference between convergent ,divergent and transform boundary
Answer:
Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.

Explanation:
the number of chromosomes in a human egg is double the number in the skin,hence diploid =46
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.

Explanation:
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.

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

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."

Answer:
The correct answer is - ulnar radial notch and the annular ligament.
Explanation:
The head of the radius and the ring formed by the ulnar radial notch and the annuar ligament that helps in an essential action or movement of supination and pronation of the upper limbs.
These two markings form a pivot joint which is known as the proximal radioulnar joint. It allows a rotational movement of the radius on the ulna at the distal end.

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.

Explain how you could use a balloon to show a friend why the universe looks the way it does.
Answer: When scientists talk about the expanding universe, they mean that it has been growing ever since its beginning with the Big Bang.
Explanation: The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest. This means that no matter what galaxy you happen to be in, all the other galaxies are moving away from you.
However, the galaxies are not moving through space, they are moving in space, because space is also moving. In other words, the universe has no center; everything is moving away from everything else. If you imagine a grid of space with a galaxy every million light years or so, after enough time passes this grid will stretch out so that the galaxies are spread to every two million light years, and so on, possibly into infinity.
