Answer:
Small birds, green plants, snakes, lizards, humans, rodents, fungi, insects.
Explanation:
Squirrels are known to be herbivores. Therefore, they can be found around budding plants and they also feed on the parts of the plants such as their seeds and fruits. Squirrels live in the same environments with humans. At times, they feed on dead rodents, lizards and snakes. They also feed on insects and fungi.
The squirrel belongs to a family of rodents known as the Sciuridae. They are tree-dwelling animals with a good sense of vision.

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).

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.

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.

Explanation:
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.

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) .

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.

Explain why the structure of a brain cell would differ from that a red blood cell.
Answer: Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.
Explanation:
Brain is composed of brain cells known as nerve cells where as RBC also known as red blood corpuscle is a component of blood.
What is the structure of a brain cell ?The brain's neurons are the cells that transmit and receive chemical and electrical messages. They serve as the brain's building blocks and act as information carriers for all of the body's neurons, muscles, and tissues. You can think, feel, move, and take in information with their help.
Erythrocytes, sometimes known as red blood cells, are one of the elements of blood. Our bone marrow continuously produces them. One billion red blood cells can be found in just two or three droplets of blood, which is what gives human blood its recognizable red color. From our lungs, red blood cells transport oxygen to the rest of our bodies. The carbon dioxide is then transported back to our lungs, where it is expelled.
Therefore, the structure of a brain cell differs greatly from red bood cell.
