Answer:
This question lacks options, options are:
A) glial cell
B) interneuron
C) sensory neuron
D) motor neuron.
The correct answer is D.
Explanation:
The brain sends instructions to the muscles that control voluntary movement through nerve cells called motor neurons. The function of the motor neuron is basically to carry the information that comes from the descending pathways of the spinal cord, in order to generate an activation in the tissues of the skeletal and visceral muscles of all parts of the body. Motor neurons need the information sent to them by sensory or efferent neurons. Since in order to perform the appropriate muscle movements for the situation, our brain must receive information from the outside. By sending sensory stimulation through interoreceptors, motor neurons can regulate visceral activity, stimulating or inhibiting the activity of their effector tissues. In this way, our nervous system integrates the information from both types of neurons and allows us to move and react according to the demands and circumstances of our external context.

All the offspring of a cross between a black-eyed mendelien and an orange-eyed mendelien have black eyes. What is the expected F2 phenotypic ratio of a cross between two F1 black-eyed mendeliens?
A) 1 black-eyed:1 orange-eyed
B) 3 black-eyed:1 orange-eyed
C) 1 black-eyed:3 orange-eyed
D) 1 black-eyed:0 orange-eyed
The phenotypic ratio of the cross is as follows: 3 red antennas: 1 white antenna
For question 2, the phenotypic ratio of the F2 generation is: 3 black-eyed: 1 orange-eyed
QUESTION 1
According to the first question, a gene coding for antenna color in butterflies is involved. Red antennas (“R”) is dominant to white antennas (“r”). Hence, a butterfly with genotype "Rr" will be phenotypically red.
According to this question, If both parents are heterozygous for red antennas i.e. Rr (red antenna) × Rr (red antenna), the following gametes will be produced: R and r. Using these gametes in a punnet square (see attached image), the following phenotypic ratio of offspring is produced:
3 RED ANTENNAS (RR, Rr, Rr) : 1 WHITE ANTENNA (rr)
2. In the second question, all the offspring of a cross between a black-eyed mendelien (BB) and an orange-eyed mendelien (bb) have black eyes (Bb). In a cross between two F1 black-eyed mendeliens i.e. Bb × Bb, the following proportion of offspring is produced:
BB, Bb, Bb, bb
Hence, a phenotypic ratio of 3 black-eyed: 1 orange-eyed

At this point, the writer is considering adding the following sentence. Successful nerve impulse transmission depends not only on myelin sheaths, but also on the presence of ion pumps embedded in the cell membrane. Should the writer make this addition here?
A) Yes, because it describes how the presence of ion pumps is related to the functions of cholesterol.
B) Yes, because it supports the passage’s main argument with a second example of cholesterol’s potential adverse health effects.
C) No, because it identifies a relationship between the nervous system and ion pumps that has already been discussed.
D) No, because it interrupts the paragraph’s discussion of cholesterol’s functions with loosely related information.
Answer:
D) No, because it interrupts the paragraph’s discussion of cholesterol’s functions with loosely related information.
Explanation:
The passage was discussing the importance of cholesterol in nerve impulse transmission. Its presence in the myelin sheaths of nerve cells speeds up nerve impulse transmission. It will not be wise for the author to now bring in the relationship between nerve impulse transmission and ion pumps. This is because the main topic under discussion is cholesterol and its importance. The sentence should be continued with other importance of cholesterol and not ion pumps.

characteristics between invertebrates and vertebrates in a tabular form.
Answer:
Invertebrates: Do not possess a backbone and doesn't have an internal skeleton. Has an exoskeleton. Are generally smaller than vertebrates. Possess an open circulatory system. The majority have compound eyes. Includes radial or bilateral body symmetry. Presence of a simple and unorganized nervous system. Mode of nutrition includes Autotrophic, Parasitic, and Heterotrophic. 95% of animal species are invertebrates. Flatworms, arthropods, sponges, insects are few examples of Invertebrates.
Vertebrates: Possess a backbone and has an internal skeleton. Does not have an endoskeleton. Larger than invertebrates. Possess a closed circulatory system. Do not have compound eyes. Has bilateral body symmetry. Presence of complex and highly specialized organ systems with specific functions. The mode of nutrition is usually heterotrophic. 5% of animal species are vertebrates. Mammals, fish, reptiles, amphibians, and birds are examples of Vertebrates.
EVOLUTION CONNECTION The history of life has been punctuated by several mass extinctions. For example, the impact of a meteorite may have wiped out most of the dinosaurs and many forms of marine life at the end of the Cretaceous period. Fossils indicate that plants were less severely affected by this mass extinction. What adaptations may have enabled plants to withstand this disaster better than animals
Answer:
Dissaster like meteorite impacted all type of living forms, however, animals are impacted the most and plants are impacted least. It is possible due to ability of plants to prepare their food on their own as they are autotrophic and use photosynthesis. The raw material for preparing these are easily available that are sunlight, CO2 and water.
They are not depende on other for their cellular respiration. The other major reason is that the Plant seeds can remain dormant in unfavorable conditions for many years in the soil. The roots always provide nutrition even the stems get effected.

Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized. If all of these genes are on the same chromosome, and there is no recombination, how many different genotypes will occur in the F2
Answer:
2 genotypes: AABBCCDDEE; aabbccddee
Explanation:
The law of segregation (also called Mendel's First Law) describes how genes on different chromosomes segregate into gametes independently of each other. Moreover, recombination (also known as crossing over) is the interchange of genetic material between non-sister chromatids during meiosis. In this case, the five genes are on the same chromosome (i.e., they are linked together and do not segregate) and there is no recombination, thereby they are inherited as a haplotype block to the next generation:
- Genotypes parental (P) lines: AABBCCDDEE; aabbccddee
- Cross P1: ABCDE X abcde
- Genotype F1: AaBbCcDdEe (100%)
- Gametes F1: ABCDE; abcde
- Genotypes F2: AABBCCDDEE; aabbccddee (ratio 1:1)
Which is a compound that allows plants to get nitrogen from the nitrogen cycle?

ASAP please!!!
Answer:
In mitosis, the results are 2 different diploid cells.
Explanation:
Mitosis is an exact replication of the parent cells, making them diploid cells. 4 haploid cells are the result of meiosis.
Answer:
When a haploid cell undergoes mitosis, it produces two genetically identical haploid daughter cells; when a diploid cell undergoes mitosis, it produces two genetically identical diploid daughter cells. ... In contrast, meiosis is considered a “reductional” form of cell division that occurs in diploid germ cells.

As with most fluid samples sent for microbiological analysis, Mandy starts her investigation with a Gram stain.
Gram Stain Analysis Classify the infectious agent based on the Gram staining.
Hi. Unfortunately your question is incomplete and you have not shown any photos of the sample that Mandy must identify by Gram stain. However, after researching her question on the internet, I was able to find another question exactly like this one, which showed the microorganism that should be analyzed. This image is attached below. In that case, I hope the answer below can help you.
Answer:
Gram-positive cocci
Explanation:
It is possible to identify that the microorganism presented is a bacteria due to the application of the test known as Gram stain, which allows the identification of gram positive and gram negative bacteria. This test allows the bacteria to be subjected to a specific dye that reacts with the chemical composition of the bacteria, modifying its color. Gram positive bacteria show a blue color after the test, while gram negative bacteria show a red color after the test.
As we can see in the attached image, the bacteria that Mandy is analyzing shows a blue color, after being submitted to Gram stain, being then a gram positive bacteria.
We can also see that the colonies of this bacterium have formed round, similar to a coconut and for this reason, we can conclude that the bacterium has the shape known as cocci.
Therefore, we can classify the microorganism as a Gram-positive cocci.
Which statement about the genetic code is false?
A. There is no punctuation or spacing between codons.
B. Codons are composed of sets of three nucleotides.
C. Every amino acid is specified by a single codon.
D. The genetic code is almost universal, but not quite.
The statement 'every amino acid is specified by a single codon' about the genetic code is FALSE (Option C).
The genetic code refers to the process by which the heritable information is passed from the DNA sequence to RNA during transcription, and then from RNA to protein during translation.The genetic code is said to be redundant because there are amino acids that can be encoded by more than one codon.For example, the amino acid leucine can be specified by four different codons (CUU, CUC, CUA, and CUG).In conclusion, the statement 'every amino acid is specified by a single codon' about the genetic code is FALSE (Option C).

Alizarin yellow is a pH indicator that transitions from red to yellow when the pH falls from a value of 11 to below 10. Why is phenol red a better pH indicator than alizarin yellow for detecting a change in pH of broth containing pathogenic bacteria such as E. coli
Answer:
The correct answer is - acidic conditions wouldn't trigger a change in the color of Alizarin yellow.
Explanation:
The growth of E. coli generally occurs at neutral pH, however, its growth is normal at acidic conditions as well. The change in the growth of E. coli is not able to detect by alizarin.
The phenol red turns yellow in the presence of an acid, and the change in pH in an alkaline environment can be detected by the red color of phenol red. Growth of E.coli will grow in pH of 10-12 . But, very slowly. The color change in alizarin is also apparent at pH 10.2 to 12 only.

Explanation:
Presence of capsule. Therefore, option (B) is correct.
What was Griffith's experiment?Griffith's experiment of transformation is a landmark experiment in microbiology conducted in 1928 by British bacteriologist Frederick Griffith. The experiment aimed to determine the nature of the "transforming principle" responsible for transferring genetic material between bacteria.
Griffith used two strains of Streptococcus pneumoniae, one that was virulent and had a polysaccharide capsule (S strain) and another that was non-virulent and lacked the capsule (R strain). He found that when he injected mice with the heat-killed S strain and live R strain, the mice died, and live S strain was found in their blood. This suggested that the R strain had been transformed into the S strain, and the genetic material was responsible for the transformation.
Griffith's experiment provided the first evidence of bacterial transformation and paved the way for future research on the molecular basis of genetics.
