Answer:
D. Phenotypic Plasticity
Explanation:
I just took the quiz and this was the correct answer.
Phenotypic plasticity simply refers to the changes in an organism's behavior, morphology and physiology in response to a unique environment. Phenotypes aren't always something visual, and in this case its the ant's pheromones that are being used ("changed") in order to aid its travels to and from food sources and ensure that it does not get lost.
This was my thought process as I figured out the question so hopefully it makes sense!!
Individual ants of the same species use pheromone trails to indicate the path to different food sources or back to their own colony. This is an example of phenotypic plasticity. Thus, the correct option for this question is D.
What is Species?Species may be defined as a group or collection of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. A species is the biggest gene pool possible under natural conditions.
Phenotypic plasticity may be defined as the phenomena through which one genotype can give rise to a range of different environmental conditions during development. It governs the ability of one genotype in order to produce more than one phenotype when exposed to different environmental conditions.
Therefore, the occurrence of ants of the same species using pheromone trails to indicate the path to different food sources or back to their own colony represents an example of phenotypic plasticity. Thus, the correct option for this question is D.

In which parent could chromosomal rearrangement have made an X chromosome with 2 fur color alleles?
Answer:
Mother
Explanation:
(see image below)
According to the given situation, the mutation needs 2 X chromosomes and only the mother has 2 X chromosomes whereas a father has X and Y chromosomes.
What are the 23 chromosome pairs?Humans have 23 pairs of chromosomes, 22 pairs of numbered chromosomes, and 1 X and Y chromosome (father) and mother have (XX) chromosomes.
Each parent donates one chromosome to each pair so that offspring get half of their chromosomes from their mother and a half from their father.
Thus, the mother is an answer.

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.
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) .

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).
Why must transcription occur where DNA can be found?
because DNA can't leave
O because DNA polymerase is found there
O because ribosomes are in the nucleus
O because helicase unzips the DNA
Answer:
because DNA can't leave
Explanation:
Transcription must occur where deoxyribonucleic acid (DNA) can be found: A. because DNA can't leave.
What is transcription?Transcription can be defined as a biological process that typically involves re-writing the information contained within a deoxyribonucleic acid (DNA) into a ribonucleic acid (RNA) by enzyme RNA polymerase.
Generally, the Transcription of deoxyribonucleic acid (DNA) produces a single-stranded ribonucleic acid (RNA) molecule that is the same with the strand of DNA used as the template.
In conclusion, transcription must occur where deoxyribonucleic acid (DNA) can be found in living organisms because DNA can't leave.

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.
