g B. PROTEINS 1. Name the gastric enzyme that initiates protein digestion. Explain how this enzyme is activated. Pepsin is the gastric enzyme that initiates protein digestion. It is activated by stomach acid into the active form. It then breaks down the protein in our food into smaller particles like peptide fragments and amino acids. 2. Name the ducts in the pathway by which pancreatic juice flows from the pancreas to the duodenum. The Pancreatic duct. 3. Describe 3 ways the body uses these amino acids..
Answer:
1-the gastric enzyme is pepsin, which is why it is a peptidase, since it catalyzes the binding of proteins within the stomach. Its activation method is the acidic pH of the stomach.
2-Pancreatic juice is a juice that hydrolyzes and helps the digestion of proteins or peptides, since this is the EXOCRINE substance of the pancreas, this juice being exocrine is poured into the main pancreatic duct of the pancreas and then through the choledochol in the blister of toilet at intestinal level.
3-amino acids are used by the body for hormonal, transport, and structural purposes. It also has other functions such as the conformation of the same DNA, but there are 3 that must be answered.
Explanation:
Proteins have structures or junctions that are quaternary, tertiary, binary, and primary.
the easiest to degrade with the quaternary and tertiary while the other two do not.
It is important that you know this fact why these structures are ordered from the outside to the inside or inside the protein, the outermost ones are the quaternary ones and the innermost ones are the primary ones.
A protein ceases to be protein and becomes free and separated amino acids when it reaches the heart of the protein and breaks the primary bond, or the sea the strongest and most difficult to break.
These amino acids have multiple functions but they can be said which, when united, are the unit that makes up proteins or peptides.

You are doing an experiment and plated E. coliin different medias. Media A has onlyglucose, B has only lactose, and media C has both glucose and lactose.You notice that some of the cultures grown in media C are metabolizinglactose. Which type(s) of mutation(s) could cause this to occur
Answer:
A. Glucose:
As lactose is absent will follow the glucose metabolism, so the lac repressor will hold tightly with the operator which leads to the prevention of transcription as RNA polymerase can not bind to promoter so no lactose metabolism.
B. lactose:
In the case or wild mutant lactose metabolism will occur as lactose is present, allolactose binds to the lac repressor thus the operator and promoter are free so transcription starts. The same result will be in all test except in the case of a mutant repressor.
C. glucose and lactose:
In this case, diauxic growth will occur. This growth takes place when two sugars are present in the media. The preferred sugar will be consumed first That is glucose. Then a lag phase will come which will be followed by the second sugar metabolism that is lactose. the given two cases :
Lactose will be metabolized first, as operator site mutation prevents repressor protein binding and thus will lead to the constitutive synthesis of lac operon in test B. The same thing will happen, as in this case also, constitutive synthesis of lac operon will happen in test C.
Cultures grown in the presence of both glucose and lactose are metabolizing lactose. In the test (b) and (c) will be responsible due to constitutive synthesis of lac operon will happen.
Hitchhiker's thumb is inherited via two recessive alleles and causes a hyperextensibility of the thumb. The dominant allele causes a straight thumb phenotype. Predict the phenotypic and genotypic ratios from the following cross.
One parent with Hitchhiker's thumb crossed with a Straight thumbed individual who had a parent with Hitchhiker's thumb.
a. Phenotypic and Genotypic 1:1
b. Phenotypic 2:1 and Genotypic 1:1
c. Phenotypic 1:1 and Genotypic 2:1
d. Phenotypic and Genotypic 3:1
Answer:
a. Phenotypic and Genotypic 1:1
Explanation:
Two recessive alleles are required in order to be phenotypically affected for Hitchhiker's thumb. Hence, the genotype of the parent with Hitchhiker's thumb would be homozygous recessive.
Assuming the trait to be represented by the allele h, the genotype of the parent with Hitchhiker's thumb would be hh while the genotype of an individual with straight thumb who had a parent with Hitchhiker's thumb would be heterozygous, Hh.
Crossing the two individuals.
hh x Hh
Progeny: Hh hh Hh hh
Hh - Straight thumb
hh - Hitchhiker's thumb
Hence, the genotypic ratio is 1:1 while the phenotypic ratio is also 1:1.
The correct option is a.

Why are detritivores, decomposers and omnivores not assigned trophic levels
Answer:
The reason is because detritivores and decomposers and omnivores are multilevel food chain consumers in an ecosystem making them not qualified to be assigned to a given trophic level
Explanation:
An organism is placed in a trophic level based the level it is from where the food chain starts with the start of the food chain having a level of 1 for the food producers such including plants and algae
Level 2 organisms are called primary consumers and consists of organism that eat only plants known as herbivores such as cattle
Level 3 organisms are called secondary consumers and consists of animal eating organism known as carnivores such as foxes etc.
Level 4 organisms are called tertiary consumers
Level 5 organisms are the a p e x p r e d a t o r s
Detritivores and decomposers such as bacteria, earthworm flies fungi consume the wastes produced at all trophic levels, therefore they cannot be assigned to a particular trophic level
Similarly, omnivores consumes both plants at level 2 and animals at level 3 making it ambiguous to assign them to one particular trophic level.
You discover a new alien race that you decide to call the PAMMARIANS. They are different from us in that they have three sexes, called Q, R, and S. All three sexes must fuse their gametes to form a new PAMMARIAN (and you thought dating on the Earth was hardi). They have nuclear DNA and extrachromosomal organelles, similar to mitochondria, called MITOCHLORIANS, which have their own DNA. The R gender is like human females (they donate the cytoplasm during the mating). Q and S do NOT donate cytoplasm during mating, like human males. Which of the following is TRUE?
A. In a mating, if only the Q gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring WILL HAVE a mitochlorian mutant phenotype.
B. In a mating, if the S and a genders have a mitochlorian DNA mutation, the offspring will be mutant as well.
C. In a mating, if only the R gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring will have NO mitochlorian mutant phenotype.
D. In a mating, if only the gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring WILL HAVE a mitochlorian mutant phenotype.
E. In a mating, if only the Q gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring will have NO mitochlorian mutant phenotype.
Answer:
Option E
Explanation:
In a mating, if only the Q gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring will have NO mitochlorian mutant phenotype.
It was discovered that an offspring always inherits the mothers mitochondrion DNA including all its defects and not from the father as the mother contributes the bulk of the cytoplasm. Thus, since the gender female is R, if she possess a mutant mitochorlian DNA, the offspring will exhibit that mutant phenotype as care to Q and S that cant pass their mutation on.

what is the job of the stomach, large intenstine, small intestine 60 points!!
Answer:
Stomach - The stomach is a hollow organ, or "container," that holds food while it is being mixed with stomach enzymes.
Large Intestine - The large intestine absorbs water and electrolytes, and produces and absorbs vitamins. It forms and propells feces toward the rectum for elimination.
Small Intestine - The small intestine breaks down food coming from the stomach and absorbs the nutrients from the food.
Cells must maintain an appropriate level of fluidity across their membranes. Hot temperatures lead to greater membrane fluidity. What might you then expect to find regarding the membrane composition of bacteria from very hot environments
Answer:
Thermophilic bacterial are rich in large quantity of thermophilic lipids in the cell membranes. This components made the membrane to be impermeable at high temperature, and therefore a good adaptation for the hot environment.
At high temperature,proton permeability increase, sodium permeability also increases but to a ;lesser extent, but Lipid is independent of this temperature rise.
Hence, these organisms rely on the less permeable Na+ for the maintenance of high sodium motive force.it is the energy derived from this that the cell membrane needs to maintain stability, coupe with the lipid content.

ma
O It is degraded.
O It is sliced into different sections.
Answer:
it binds together
Explanation:
dna is commonly present in the shape of a molecule with double strands. In a similar way, these two molecules connect to each other in a mechanism called hybridisation. DNA naturally, the new strand hybridizes to the old strand when it is replicated.
hope this helped!
During hybridization, DNA strands bind together. The correct option is A.
The process of joining two complementary strands of DNA from various sources to create a double-stranded molecule is referred to as hybridization.
The complementary DNA strands join together during this phase and create strong hydrogen bonds between their corresponding base pairs. Adenine (A) and thymine (T) and guanine (G) and cytosine (C) couple up specifically to form this interaction.
Numerous molecular biology procedures, including DNA hybridization tests, polymerase chain reaction (PCR), and DNA sequencing, frequently employ hybridization.
Hybridization enables the identification and amplification of particular DNA sequences as well as the analysis of genetic data by allowing the complimentary strands to come together.
Thus, the correct option is A.
