D) AUG-UAU-CGA-GGA-GUU-GCG-CUC-UGA
What is messenger RNA?
Messenger RNA (abbreviated mRNA) is a type of single-stranded RNA involved in protein synthesis.
What is codon GCA code?
The three consecutive DNA bases, called nucleotide triplets or codons, are translated into amino acids (GCA to alanine, AGA to arginine, GAT to aspartic acid, AAT to asparagine, and TGT to cysteine in this example).
What are the 3 stopping codons?
A stop codon is a sequence of three nucleotides (a trinucleotide) in DNA or messenger RNA (mRNA) that signals a halt to protein synthesis in the cell. There are 64 different trinucleotide codons: 61 specify amino acids and 3 are stop codons (i.e., UAA, UAG and UGA).

It has been proposed that the presence of black markings on the throat of kung fu geckos is coded by a dominant allele (B) and that the absence of such markings is coded by a recessive allele (b). To test this idea, heterozygous individuals are crossed (Bb x Bb) producing 500 offspring of which 350 have black markings and 150 don’t have black markings. Based on a punnett square, the expected phenotypic ratio for black markings to no black markings is 3:1.
Required:
Write down the correct statistical approach to test if the data is consistent with the expected 3:1 ratio.
Answer:
See the answer below
Explanation:
The correct statistical approach to test if the data is consistent with the expected 3:1 ratio would be the Chi square.
Chi-square = [tex]\frac{(O - E)^2}{E}[/tex] where O = observed frequency and E = Expected frequency. In this case:
Phenotype O E Chi square
Blacks 350 3/4 x 500 = 375 [tex]\frac{(350-375)^2}{375}[/tex] = 1.67Non blacks 150 1/4 x 500 = 125 [tex]\frac{(150-125)^2}{125}[/tex] = 5Total Chi square = 1.67 + 5 = 6.67
Degree of freedom = 1
Tabulated Chi square = 3.841
Since the calculated Chi-square is more than the tabulated value, the null hypothesis is rejected and we conclude that the data is not consistent with the expected 3:1 ratio.

The ribosome binds to a strand of _____
This nucleic acid has
three-nucleotide codes called ______
The three-letter codes are complementary
to ________
on ________
molecules. Each of these
molecules brings with it an amino acid, which will become part of the growing polypeptide.
Answer:
The correct answer is - mRNA, codons, anticodons, RNA.
Explanation:
During the translation process of protein synthesis, the mRNA strand is attached with the ribosome in order to translate the three-letter nucleotide sequence that is called codons or triplet code into specific amino acids.
These three-letter codes are complementary to the anticodons on the RNA (tRNA) molecules. These nucleic acid molecules with ribosomes bring with them an amino acid to make a polypeptide chain.
The pancreatic enzymes trypsin, chymotrypsin, and elastase all hydrolyze peptide bonds on the carbonyl side of several different amino acids in a protein. What term best describes their enzyme specificity
Answer:
the term that best describes their group specificity is group-specific.
Explanation:
These enzymes are group-specific because their specificity is on catalyzing a particular functional group present in some proteins. In this case, the enzymes are group-specific due to the fact that they hydrolyze peptide bonds by acting on the carboxyl group of the amino acid.

a. a flat plain
b. a trench
c. a mid-ocean ridge
d. a continental shelf
Answer:
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

A lipoprotein particle functions to ________. dissolve polar lipids for excretion transport nonpolar lipid to body cells metabolize lipids into new substances dissolve polar lipids in urine store lipids in the tissues
Answer:
The correct answer is ''transport nonpolar lipid to body cells''
Explanation:
Lipoproteins are macromolecules whose function is to package insoluble lipids in the aqueous medium of plasma and transport them from the intestine and liver to peripheral tissues. They transport all the lipids that circulate in the plasma: free and esterified cholesterol, triglycerides and phospholipids. Plasma lipoproteins constitute a polydisperse and heterogeneous system of particles of almost spherical morphology, which have a hydrophobic nucleus or core formed by nonpolar lipids, that is, esterified cholesterol and triglycerides, and by a hydrophilic surface layer containing unesterified cholesterol, phospholipids and specific proteins called apoproteins.
a car moves takes in fuel releases energy from fuel gets rid of waste through the exhaust pipe is a car living thing
Answer:
The correct answer is - no, the car is not a living thing.
Explanation:
All living organisms have definite life processes that are characteristics of a living organism and are common in every living being. There are seven life processes that determined and need to do to count as a living thing, that are -
1. Movement - all living things show some type of movement, even plants
2. Respiration - required to get energy from food
3. Sensitivity - sense what is happening around
4. Growth - all living things grow
5. Reproduction - increasing number of the same type
6. Excretion - removal of biological waste
7. Nutrition - utilizing food
A car shows movement and the ability to get energy from fuel similarly as respiration and nutrition can show sensitivity if an alarm installed, and removes waste through exhaust pipes like excretion. However, it can not grow or make another same type like reproduction, So a car is not alive.

g The dominant food chain in a kelp forest ecosystem is made up of the three species below, listed with their trophic levels. If sharks enter a kelp forest ecosystem and begin feeding on sea otters, they would have a positive indirect effect on which species
Answer:
Crustaceans, sea urchins, mollusks and fish.
Explanation:
The positive effect occurs on crustaceans, sea urchins, mollusks and fish if the shark feeds on sea otter because sea otter feeds on crustaceans, sea urchins, mollusks and fish. Decrease occur in the population of sea otter due to introduction of shark in the ecosystem which indirectly increases the population of crustaceans, sea urchins, mollusks and fish. So we can say that a positive indirect effect occurs on crustaceans, sea urchins, mollusks and fish due to shark.

g Name and describe two possible pathogens that could be responsible. The spinal tap reveals the presence of Gram-negative cocci in the CSF. What would be the likely diagnosis
Answer:
Explanation:
The missing information describing the status of the sick sophomore student is attached in the image below.
The first question says we should name and describe the two possible pathogens responsible for such.
The two possible pathogens are:
Virus and Bacteria.
Recall that, the College student experienced a severe headache, nausea, vomiting, neck stiffness, and fever.
These highlighted symptoms are commonly caused by meningitis which is a bacterial infection.
Surgeons, surgical tools, and scrub nurses must all be sterile when doing surgery; If any infection arises provided all crucial measures were not taking into consideration, it would harm the patient and there will be a risk of meningitis as a result of this.
SImilarly, given that In the CSF, the presence of Gram-negative cocci is shown via a spinal tap; then the likely diagnosis would be that:
The patient has suffered from Neisseria meningitis.
This is because Gram-negative cocci are the most prevalent cause of infection in persons of this age group and In the Gram stain test, it has a dark red color.
Comprehensive detail and links between structure and functions of animal cells and different tissue in animals
Answer:
Great relationship.
Explanation:
There is a great relationship between the structure and functions of animal cells because the structure of cells helps the cell to perform a particular function assign to it. The cells in epithelial tissue are tightly packed together with a very little intercellular matrix. intercellular matrix is a non-living material used to fill the spaces between the cell. Due to this structure, the epithelial tissue forms the covering of all body and helps in protecting the skin.
