Answer: B. Adaptive radiation formed many new land plant species
Explanation:
After plant first moved to land adaptive radiation formed many new land species
What is adaptive radiation?"Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into new species due to change in the environment."The species adapt themselves to varied habitat in order to survive and the number of species increases.What is species?"It is a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding."Hence, the correct option is B. Adaptive radiation formed many new land plant species.

What is the difference between genetic and chromosomal mutations
Answer:
Gene mutation may alter the function of proteins in the body. Chromosomal mutations can be either an alteration of chromosome structure or chromosome number. ... The main difference between gene mutation and chromosomal mutation is the magnitude of alterations that occur in the genetic material by each type of mutation.
Can a gene mutation that does not influence phenotype be considered an adaptation? Why or why not?
Answer:
No; only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.

Explanation:
Mutations rII1 and rII2 are known to fall into the rIIA and rIIB cistrons (genes) respectively. Cells of E. coli B are infected simultaneously with phage strains rII1 and rII2 at a high moi. The progeny phage are collected and used to infect cells of E. coli K. This infection is also carried out at a high m.o.i., and the resulting phage are collected. These progeny are diluted and plated on both E. coli B and E. coli K. Do you expect more plaques on strain B, on strain K, an equal amount on both or is it impossible to tell?
A. E. coli B
B. E. coli K
C. Equal on both
D. Can't tell
Answer:
the answer is A. E. coli B
Explanation:
The multiplicity of infection (MOI) refers to the ratio between the numbers of viruses used to infect E. coli cells and the numbers of these E. coli cells. Benzer carried out several experiments in order to define the gene in regard to function. Benzer observed that E. coli strains with point mutations could be classified into two (2) complementary classes regarding coinfection using the restrictive strain as the host. With regard to his experiments, Benzer observed that rII1 and rII2 mutants (rapid lysis mutants) are complementary when they produce progeny after coinfect E. coli K (where neither mutant can lyse the host by itself). The rII group of mutants studied by Benzer does not produce plaques on E. coli K strains that carry phage λ (lysogenic for λ), but they produce plaques on E. coli B strains. This study showed that rIIA and rIIB are different genes and/or cistrons in the rII region.
Given is a strand of DNA, fill in the corresponding RNA strand and find which amino acids that strand codes for.
Please help!
Answer:
RNA: [tex]A-U-G-U-A-U-A-C-G-G-A-U-U-G-A[/tex]
Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid
Explanation:
1) First, transcribe the DNA to RNA. For each nitrogenous base (to put it simply, the letter) listed in the DNA strand, write the strand of RNA with the matching nitrogenous base. Remember that, when transcribing, the thymine (T) from DNA can pair with adenine (A) in the RNA, adenine (A) pairs with uracil (U), and cytosine (C) and guanine (G) always pair with another.
DNA: [tex]T-A-C-A-T-A-T-G-C-C-T-A-A-C-T[/tex]
RNA: [tex]A-U-G-U-A-U-A-C-G-G-A-U-U-G-A[/tex]
2) Next, to find the amino acids the strand codes for, read the nitrogenous bases in the RNA from left to right in groups of three, or codons. Then, using a codon chart, find which amino acid the group of three bases codes for. This gives the following answer below. (Remember that the codon UGA stops the translation and therefore does not code for an amino acid.)
Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid
Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid
What are amino acids?Amino acids are the building blocks of protein. Proteins are long chains of amino acids. Your body has thousands of different proteins that each have important jobs. Each protein has its own sequence of amino acids.
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids.
The human body uses amino acids to make proteins to help the body: Break down food. Grow. Repair body tissue.

What factors play a role in how fast, far, or what direction DNA fragments travel for gel electrophoresis?
Explanation:
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode, Shorter strands of DNA move more quickly through the gel than longer strands resulting the fragments being arranged in order of size.

Which of the following best describes a precipitate?
A measure of mass per unit of volume
A solid separated from a solution
A form of weather
A clear indication of a physical change
Answer:
In chimica, un precipitato è un solido insolubile che emerge da una soluzione liquida. L'emergenza del solido insolubile dalla soluzione è chiamata precipitazione. Spesso il precipitato emerge come una sospensione. I precipitati possono formarsi quando due sali solubili reagiscono in soluzione per formare uno o più prodotti insolubili.
Explanation:
A solid separated from a solution best describes a precipitate. So, the correct option is B.
What is Precipitate?Precipitation is the process of formation of a solid substance in a solution, either by physical mixing of low-solubility chemicals or by a chemical reaction of two or more compounds. Precipitate refers to the solid that eventually forms as a result. A solid that separates from a solution during a chemical reaction is known as a precipitate.
When two or more compounds are combined, they react to form an insoluble product, which is how it is formed. A precipitate may take the form of a suspension in solution or a solid that settles to the bottom of a solution. It can be removed from a liquid using a number of techniques, including filtration and centrifugation. Many chemical reactions require precipitates, which are often used to separate, purify, or identify different compounds.
Therefore, the correct option is B.

Mendel demonstrated which of the following about inherited traits? Check all that apply.
certain traits are more likely to appear than their alternatives.
some traits show blending inheritance.
traits segregate among the offspring of a cross.
traits can be hidden in some generations, but subsequently reappear unchanged in future
generations.
parents that both have the same trait can have offspring with an alternative trait.
Answer:
The correct answer would be -
certain traits are more likely to appear than their alternatives.
traits segregate among the offspring of a cross.
traits can be hidden in some generations, but subsequently, reappear unchanged in future generations.
parents that both have the same trait can have offspring with an alternative trait.
Explanation:
Mendel is known as the father of genetics for his tremendous work in the field of genetics by performing experiments on the pea plants which contribute to the make the law of inheritance. According to all three laws of inheritance and experiments performed by Mendel, he demonstrated inheritance patterns in the traits or the alleles inherited to the next generation.
Certain traits that are dominant are more likely to appear than their recessive alternatives. Trait segregates when gametes form during the cross. In heterozygous cases, some traits can be hidden but can reappear unchanged in future generations.

Why is ATP like a charger battery and ADP is like an uncharged battery ?
Answer:
When a cell has no available energy, it is able to store energy by adding a phosphate group to an ADP (adenosine diphosphate) molecule. The ATP molecule that results is like a battery because both the molecule and a battery contain stored energy, while, on the other hand, ADP is a partially charged battery.
