Answer:
The stomach produces hydrochloric acid.It kills many harmful microorganisms that might have been swallowed along with the food.The enzymes work best in acidic conditions-at low pH
Hydrochloric acid is an important component of the gastric juice in animal species such as humans. This maintains the pH in the stomach.
What is Hydrochloric acid?Hydrochloric acid is also known as muriatic acid, it is an aqueous solution of the compound hydrogen chloride. Hydrochloric acid is a colorless solution with a distinctive pungent smell. It is mainly classified as a strong acid. However, it is a component of the gastric acid in the digestive systems of most of the animal species, including humans. Hydrochloric acid is an important component of the digestive system.
Hydrochloric acid (HCl) is a part of the gastric juice. It plays an important role in creating the pH required for pepsin activity and for the maintenance of this pH. Parietal cells in the stomach are responsible for the production of HCl acid by secreting hydrogen and chloride ions separately. When pepsinogen and hydrochloric acid exist together in the gastric juice, pepsin is converted into its active form.

If a protein will end up with 30 amino acids, how many codons, not including the STOP codon, were on the mRNA
transcript that produced it?
Answer:
30 codons
Explanation:
Translation is the second process of gene expression, which involves the synthesis of amino acid sequence from mRNA. This process occurs in the ribosome where the mRNA is read in a group of three nucleotide bases called CODON. Each codon specifies a particular amino acid.
Since one codon specifies or translates into one amino acid, a protein with 30 amino acids will contain 30 codons (exclusive of STOP CODONS) on the mRNA transcript.
g One benefit of operons in bacteria is that they a. do not need ligands and regulatory proteins as single genes would. b. do not need any modification of the proteins after they are expressed. c. allow for alterations in DNA sequence by flipping promoters around. d. allow for coordinated gene expression of related genes on one mRNA controlled by one promoter. e. allow the bacteria to use a wide variety of carbon sources.
Answer:
d. allow for coordinated gene expression of related genes on one mRNA controlled by one promoter.
Explanation:
An operon is a group of functionally-related genes that share the same promoter region and the same operator which interacts with specific repressors or activators, and they are transcribed as a unit. This transcriptional unit (operon) is present in prokaryotic organisms (i.e., bacteria and archaea) but absent in eukaryotes. In an operon, each structural gene is known as a cistron, and they are transcribed together as a polycistronic primary messenger RNA (mRNA).

If a DNA codon changes from TTA to TTC, what amino acid would the matching mRNA sequence code for?
Answer:
TTC codon encodes for Phenylalanine (Phe)
Explanation:
A codon (also known as a nucleotide triplet) is a sequence of DNA or RNA composed of three consecutive nucleotides. During protein synthesis, each codon specifies a particular amino acid or stop signal (i.e., termination codons). There are 64 possible codons, 61 encode for amino acids, while three (3) codons represent stop signals (e.g., UAG, UAA, UGA). In this case, TTC (i.e., UUC codon in the mRNA) codon encodes the amino acid Phenylalanine, while TTA (i.e., UUA codon in the mRNA sequence) codon encodes the amino acid Leucine.

A coyote runs 30 meters across the field in 120 seconds. Find the SPEED
of the coyote. Include units and all digits. *
0 points
Your answer
Answer:
The correct answer is - 15 m/min.
Explanation:
Given:
Distance = 30 meter
Time = 120 second or 2 minutes
speed = ?
We know:
The speed of any moving can be calculated by the distance it traveled per unit of time,
So,
speed = Distance/time
Solution:
Speed of coyote = 30/2 meter/min
= 15 meter/min or 0.9 km/hour
Thus, the correct answer is - 15 meter/min or 0.9 km/hour
Collagen diseases are a group of human diseases in which the production of collagen throughout the body becomes impaired. Some examples of collagen diseases include systemic lupus erythematosus (SLE or lupus), rickets, and osteogenesis imperfecta. Explain why these diseases often affect the entire body. Hint: Consider the distribution of connective tissue throughout the body.
Answer:
Explanation:
Collagen vascular disease is group of disease that affects the connective tissue.
Collagen is a protein based connective tissue that includes collagen and Elastin.
Collagen is found in the tendons, ligaments, skin, cornea, cartilage, bone and blood vessels while Elastin is a stretchy and formed the major component of ligaments and skin. This connective tissue holds, protect and connect and bind various body structures together both bones, ligaments, and muscles together. When a patient then has a connective tissue disease, the collagen is affected, the elastin are inflamed and every structure connected to the proteins in the body parts are harmed.
explain what would likely happen if there were no shrimp in the close ecosystem
Answer:
It greatly affect population of fish.
Explanation:
If there were no shrimp in the close ecosystem then many fishes die due to lack f food because shrimp is the food of many small and large fishes. They also play a great role in protection of fish's skin by eating parasite, bacteria and fungi present on their skin so it also act as scavengers so if these shrimps are not present many fishes die due to various diseases and the ecosystem would be disturb.

Which conclusion is supported by the fact that meat-packers cannot sell meat that has been infested with certain parasites?
O Parasite infestations are rare and disastrous.
Parasite infestations lead to economic loss.
Parasite infestations topple even lucrative farms.
Parasite infestations are easily prevented.
Answer:
Parasite infestations lead to economic loss
Explanation:
Parasites are organisms that live on or in another organism called the 'host', obtaining their food or some other benefit (e.g., a suitable habitat/environment) from this host. Most parasites are known to affect their hosts by invading their organ systems, thereby producing parasitic infestations. In livestock, parasitic infestations can produce substantial losses of productivity. Some of the most important factors associated with parasitic infestations include, among others, poor hygienic conditions, contaminated water, unmanaged livestock waste, etc.
The correct answer is Parasite infestations lead to economic loss.
The term "parasite" refers to an organism that lives on or in another organism, or "host," and depends on it for food or some other advantage (such as a suitable habitat or environment). The majority of parasites are known to infest their hosts' organ systems and negatively impact them, resulting in parasitic infestations. Infestations of parasites in animals can result in significant productivity losses. Poor hygienic conditions, unclean water, uncontrolled livestock waste, etc. are some of the most significant causes linked to parasite infestations.

EMB agar is a medium used in the identification and isolation of pathogenic bacteria. It contains digested meat proteins as a source of organic nutrients. Two indicator dyes, eosin, and methylene blue inhibit the growth of gram-positive bacteria and distinguish between lactose fermenting and non-lactose fermenting organisms. Lactose fermenters form a metallic green or deep purple colonies, whereas the non-lactose fermenters form completely colorless colonies. EMB agar is an example of which of the following?
a. a selective medium onlyb. a differential medium onlyc. a selective medium and a chemically defined mediumd. a selective medium, a differential medium, and a complex medium
Answer:
a selective medium, a differential medium, and a complex medium
Explanation:
EMB Agar (Eosin Methylene Blue Agar) is both a selective and differential culture medium that slightly inhibits Gram-positive bacteria and can be used to distinguish bacteria capable of fermenting lactose from those that are unable to ferment this disaccharide. This medium is commonly used for isolation and differentiation of coliforms (i.e., bacteria found in the soil and water samples) and fecal coliforms (bacteria found in the gut and feces samples). In EMB agar, lactose-fermenting-gram-negative bacteria (e.g., E. coli) will form colored colonies, while non-lactose-fermenting-gram-negative bacteria will form colorless colonies (e.g., Salmonella). EMB agar is composed of lactose, gelatin, methylene blue dye and eosin Y dye ( a xanthene dye) .
