Answer:
$81
Explanation:
7 times 9 is 63, so they spent 63 dollars on tickets. If 18 dollars are spent on snacks on top of that, then the group of friends spent 81 dollars in total. If you were to estimate the answer before solving it, $90 would be the closest answer of the four listed.
Answer:
The answer is $90

In DNA, different alleles of a gene have a different sequence of ___________________. Alleles may have a different sequence of ___________________ in RNA that result in a different sequence of _________________ in a protein. Therefore, proteins produced from different alleles of a gene may have different structures and functions and result in different characteristics.
Answer:

Explanation:
hahahahahaahahahaha
In DNA, different alleles of a gene have a different sequence of nucleotides. Alleles may have a different sequence of nucleotides in RNA that result in a different sequence of amino acids in a protein. Therefore, proteins produced from different alleles of a gene may have different structures and functions and result in different characteristics.
What are nucleotide?Nucleotides are the building blocks of DNA and RNA. They are composed of a sugar, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base thymine is replaced by uracil (U). The sequence of nucleotides in DNA or RNA determines the sequence of amino acids in a protein. Proteins are made up of long chains of amino acids, and the sequence of these amino acids determines the protein's three-dimensional structure and function.
Alleles are different versions of a gene. They can result from mutations or changes in the DNA sequence. Different alleles of a gene can produce proteins with different structures and functions, which can result in different characteristics in an organism. For example, the gene that determines eye color has several different alleles, which can result in different eye colors in people.

HAIR ANALYSIS
An investigator is excited to find a hair with the follicle attached when searching for evidence at a crime scene. Explain why the investigator might be excited.
The fact they hair follicles contains cellular materials rich in DNA will give them a strong lead in their investigation. Hence, the excitement.
The bottom of the hair follicle marks the point where hair growth begins, Investigators are often helped in their crime research by the outcome of DNA test. Therefore, investigators often seek materials or elements at crime scenes which could be evaluated to gives DNA result of potential suspects.Therefore, the fact that hair follicles contain cellular materials which are rich in DNA, will excite investigators as that have obtained a key lead in their investigation.

3)What is the epiglottis?
4)Why do the walls of the stomach secrete hydrochloric acid?
5)Which TWO parts of the alimentary canal make up the small intestine?
Answer:
3)The epiglottis is a small, movable "lid" just above the larynx that prevents food and drink from entering your windpipe. But if the epiglottis becomes swollen — either from infection or from injury — the airway narrows and may become completely blocked.
4)Your stomach lining also secretes hydrochloric acid, which creates the ideal conditions for the protein-digesting enzymes to work. The potent hydrochloric acid kills bacteria, protecting your body from harmful microbes which can enter your body in food.
5)Made up of three segments -- the duodenum, jejunum, and ileum -- the small intestine is a 22-foot long muscular tube that breaks down food using enzymes released by the pancreas and bile from the liver.

Penicillin-binding protein 2a, encoded by the medA gene, isn’t affected by beta-lactam antibiotics.
True
False
Answer:
The correct answer is - false.
Explanation:
Penicillin-binding protein 2a or PBPs are protein produced by bacteria that binds with the β-lactam antibiotics such as penicillin. They play role in the cell wall synthesis of bacteria by producing peptidoglycan by catalyzing the reaction.
β-Lactam antibiotics bind with the PBPs and cause the disruption to peptidoglycan cross-linking in the biosynthesis of the cell wall and ultimately lysis of bacteria takes place and cell death.

How does the amount and type of fuel impact the distance a spacecraft can travel?
A space ship's momentum will continue to carry it forward indefinitely at a constant speed after the engines are turned off.
What do you mean by momentum?Momentum in a simple way is a quantity of motion. Here quantity is measurable because if an object is moving and has mass, then it has momentum. If an object does not move then it has no momentum.
Momentum, finance, refers to the capacity for a price trend to sustain itself going forward. Strong momentum can continue in an upward or downward trend, which can be confirmed by changes in trading volume and other technical indicators.
Momentum is how we measure mass that is in motion. Any moving object will have momentum. Under the law of physics, the object's momentum equals mass times velocity. Momentum is affected by the parameters' mass as well as velocity.

You are interested in tracking a particular trait. To begin your studies you do a dihybrid self cross. What percentage of the offspring will be dihybrids themselves
Answer:
4/16 (i.e. 25%)
Explanation:
A dihybrid cross is a cross between two organisms/lines/genes that are hybrids (i.e., heterozygous) for two different traits. In a standard dihybrid cross, there is a relation of complete dominance for both loci, i.e., there are two alleles that are completely dominant and thus mask the effects of the corresponding recessive traits. In a dihybrid cross involving two different genes that assort independently into gametes during meiosis, with dominant alleles "A" and "B" and recessive alleles "a" and "b", respectively, the expected phenotypic ratio will be 9:3:3:1 (ie. 9/16 A_B_, 3/16 A_bb, 3/16 aaB_ and 1/16 aabb), while the expected genotypic ratio of double heterozygous "AaBb" individuals will be 4/16, i.e. 25%.
Representation:
P generation >> AaBb (father) X AaBb (mother)
Gametes (for both parents) >> 1/4 AB; 1/4 Ab; 1/4 aB; 1/4 ab
F1 generation >> 1/16 AABB; 2/16 AABb; 2/16 AaBB; 4/16 AaBb; 1/16 AAbb; 2/16 Aabb; 1/16 aaBB; 2/16 aaBb; 1/16 aabb

which of the following statements best describes how the traits of an organism are determined by the DNA in their cells?
Answer:
C. DNA codes for proteins which allow an organism to grow and function
Explanation:
Deoxyribonucleic acid, commonly known as DNA is the genetic material in living organisms. The DNA stores genetic information, which encodes the formation of useful products (proteins) necessary for the growth and development of that particular organisms. The information in DNA is decoded by a process called GENE EXPRESSION, which encompasses transcription and translation.
Transcription is the process that synthesizes RNA from DNA molecule, while translation synthesizes PROTEIN from the mRNA. Hence, the order which is called CENTRAL DOGMA OF BIOLOGY is as follows: DNA → RNA → PROTEIN.
Therefore, DNA codes for proteins which allow an organism to grow and function best describes how the traits of an organism are determined by the DNA in their cells.
