Explanation:
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).

In actuality, the DNA sequence of the human genome is NOT random. Some sequences, including some very large sequences, are repeated many times throughout the human genome. Write two ideas you have for how this fact complicates the use of CRISPR gene-editing technology in humans.
Answer:
repeated DNA sequences decrease the target specificity of the CRISPR-Cas system, and may lead to off-target effects
Explanation:
The CRISPR-Cas system is a versatile and powerful tool for gene editing. This gene-editing tool consists of a single guide RNA (sgRNA) that guides the Cas endonuclease protein to the appropriate genomic locus, where Cas generate a double-strand break in the DNA and thus induces DNA repair either by Non-homologous end joining (NHEJ) or Homologous Recombination (HR) repair pathways. The sgRNA consists of a 17-20 nucleotide sequence which is complementary to the target DNA, this sequence is called crispr RNA (crRNA). The existence of repeated DNA sequences hampers the specificity of the CRISPR-Cas tool because a particular sgRNA is able to guide Cas9 to different genomic loci that have the same (repeated) nucleotide sequence complementary to the crRNA. In consequence, repeated DNA sequences may lead to undesired off-target effects, i.e., unintended cleavage (and therefore unintended mutations) at untargeted genomic sites.

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.

Explanation:
Crickets "chirp" by rubbing their wings or legs over each other. This phenomenon is known as stridulation. It is a means by which male crickets "call" to females to communicate their interest in mating. Frequency refers to the number of chirps that crickets produce during a period of time. Some have suggested that you can tell the temperature and the humidity based on how fast crickets chirp.
Required:
a. What is the effect of temperature on the frequency of cricket chirping? As the temperature rises, the cricket chirp occurs more rapidly therefore increasing.
b. What is the effect of humidity on the frequency of cricket chirping? As the humidity rises, the cricket chirp frequency occurs more rapidly therefore increasing.
Answer:
a. As the temperature rises, the cricket chirp occurs more rapidly therefore increasing. It is correct.
b. As the humidity rises, the cricket chirp frequency occurs more rapidly therefore increasing. It is incorrect. The increase in humidity does not affect the chirp frequency in crickets.
Explanation:
As temperature increases, the frequency of cricket chirp increases too. After listening to the audios, we can see that in the first audio, where the temperature is 14° Celcius, the frequency is 24 chirps in 15 seconds. In the second audio, with 19° Celcius, the frequency is 28 chirps in 15 seconds. In the last audio, where the temperature is 24° Celcius, the chirp's frequency is 34 chirps in 15 seconds. In conclusion, if the temperature increases, the chirps' frequency increases too.
As humidity increases, the frequency of the chirp does not. In the three audios, the number of chirps in 15 seconds was 20. We can conclude that humidity does not affect the frequency of chirps frequency.
What is the wavelength of an X-ray whose frequency is 2.0 × 1018 Hz? Hint: An X-ray is an electromagnetic wave, so its velocity is equal to the speed of light (3.0 × 108 m/s).
A.
1.5 × 10-10 m
B.
3.0 × 10-8 m
C.
6.0 × 10-9 m
D.
0.6 × 10-11 m
Answer:
A. 1.5 × 10-10 m
Explanation:
Given the following data;
Frequency = 2.0 × 10^18 Hertz.
Speed of light = 3.0 × 10^8 m/s
To find the wavelength;
Wavelength = speed/frequency
Substituting into the equation, we have;
Wavelength = 3.0 × 10^8/2.0 × 10^18
Wavelength = 1.5 × 10-10 meters.

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.

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.
1. Discuss how the study of fossils provides strong evidence for evolution. (13.2 and 13.3)
Answer:
in fossils we see homologous structures that suggest a common ancestor.
By looking at the bones of the arms and comparative anatomy we see the similar structure and function that is retained.
When looking at other animals like birds we see Analogous structures that look similar but have a different function (flying).
Finally we see Vestigial structures which are structure that no longer function as they once were used for. An example of this is the coccyx (tail bone in humans) compared to tails in dogs, cats, monkeys, etc.
