Which of the following is not an example of a protist?
Paramecium
Kelp
Snail
Algae
A snail IS NOT an example of a protist. Protists are unicellular organisms, whereas snails are pluricellular organisms (i.e., snails are animals).
A protist is a broad category of eukaryotic organisms that are not animals, plants, or fungi.
The features of protists include:
Unicellular (i.e., they contain a nucleus)Presence of mitochondria.They can be parasitic microorganisms They prefer aquatic/moist environments.Protists include Protozoa (animal-like heterotrophic organisms), Protophyta (plant-like autotrophic organisms) and Molds (fungi-like organisms).
In conclusion, a snail IS NOT an example of a protist. Protists are unicellular organisms, whereas snails are pluricellular organisms (i.e., snails are animals).

Multiple select question.
Subdivision of the peripheral nervous system
Subdivision of the central nervous system
Controls skeletal muscles
Controls smooth and cardiac muscle
Effectors are under involuntary control
Effectors are under voluntary control
Answer:
Subdivision of the peripheral nervous systemControls smooth and cardiac muscleEffectors are under involuntary controlExplanation:
The Autonomic nervous system is a subdivision of the Peripheral nervous system and it is in charge of the involuntary processes in the body such as blood pressure, respiration and the heart rate. As such, its effectors are under involuntary control.
The Autonomic nervous system controls the smooth and cardiac muscles in the body as well as the glands. This is where it earns its other name, the Visceral nervous system.

Breathing heavily after running a race is your body's way of *
a. restarting glycolysis.
b. recharging the electron transport chain.
c. repaying an oxygen debt.
d. making more citric acid.
Answer:
The correct option is C.
repaying an oxygen debt.
Explanation:
This is because while running, humans breath shallowly which could not provide the oxygen requirement for the respiratory system and fit in for blood need.
After running, you tend to breathe heavily because your muscle work very hard , the body use more oxygen and produced more carbondioxide, therefore the lungs and respiratory system must try to provide more oxygen to the blood. sympathetic nerves stimulate respiratory muscles
so as to increase the rate at which we breathe.
Describe how random mutation in an individual can result in a new adaptation in a population? pls help TwT
Answer:
See below
Explanation:
If a random mutation results in an increase in fitness (provides an advantage in survival/reproduction), thorugh natural selection, the mutation and its corresponding trait will become more prevalent. Those individuals with the advantage will be able to outcompete those without it in a limited-resource environment.

For a specimen of an active motile microorganism, the most effective microscope for visualization would be the phase contrast microscope.
The phase contrast microscopy is a technique designed to make images of live, colorless, and transparent microbes visible by enhancing the contrast. Most light microscope requires that microbes are killed and stained before they can be visible. The phase contrast technique uses optical mechanism such that any slight variation in the phase of the organism leads to a change in amplitude and can be seen in the contrast of its image under the microscope.In summary, the phase contrast microscope would be the most effective microscope to use when a live microbe specimen is in question due to the fact that it would use a phase change to create an enhanced image without having to kill or stain the microbe.

A student collected samples of cells from a woody plant during the spring and produced the drawings below. Sample 1 was collected from the woody stem of the plant. Sample 2 was collected from the root tip of the plant. Cells in different steps of mitosis are labeled with letters A, B, C, D, and E in Sample 2. Describe the role of mitosis in the growth of a plant.
The provided question is incomplete, however, the question asked is a very generalized question, answering it on the knowledge of mitosis.
Answer:
The correct answer is - mitosis has a great role in the growth of plants.
Explanation:
Mitosis is a type of cell division that occurs in the somatic cells of an organism. During mitosis, a parent cell divides into two daughter cells with the same number of chromosomes. There are no recombination takes place. This type of cell division is fast.
Mitosis occurs during asexual reproduction in the form of budding, propagation as well as repairing of the cells as they are fast, such as the regeneration of new cells. The growth of plants and development is dependent on mitosis as they produce cells more efficiently and fast and mitosis is the only cell division found in somatic cells.

Hello all. I really need help immediately with this question. Here is the question! Explain how these terms work together IN TRANSLATION: mRNA, tRNA, codon, amino acid, protein
Thank you sm for the help :)
Answer:
Translation takes place in 3 main steps: initiation, elongation and termination.
In initiation, the ribosome binds with the mRNA strand and a initiation complex forms. An initiator tRNA molecule brings the first amino acid, methionine. It binds with the start codon using its anticodon, UAC. The large ribosomal subunit then binds to the small ribosomal subunit.
In elongation, more charged tRNAs bring the amino acids to be added on the growing polypeptide chain. Elongation continues until the ribosome encounters the stop codon.
In termination, a release factor binds to the stop codon, causing the polypeptide to be released from the ribosome. The ribosomal subunits separate from the mRNA and from each other. The polypeptide undergoes folding to form secondary and tertiary structures to become a fully-functional protein.
Notes:
• Translation is the process by which a protein is synthesized from mRNA.
• mRNA: messenger RNA
• tRNA: transfer RNA
• codon: A 3-nucleotide sequence that codes for a specific amino acid. For example, AUG codes for methionine.

There are two alleles and 3 genotypes for the C gene locus (incomplete dominance). Individuals with different genotypes vary in their relative fitness. If the relative fitness of C1C1 individuals is 1.0, the relative fitness of C1C2 individuals is 0.9, and the relative fitness of C2C2 individuals is 0.8, which of these should result in future generations
The given question lack the choices of result that might come, however, the choices related to this question is as follows:
A. frequency of C1 will increase
B. frequency of C2 will increase
C. frequency of heterozygotes C1C2 will increase
D. frequency of both same alleles will increase
E. not enough information provided to predict
Answer:
The correct answer is - option A. Frequency of C1 will increase.
Explanation:
In incomplete dominance, the relative fitness of heterzygous cases place always in between the other two allele genotype cases. In the given question, the relative fitness of C1C2 individuals is 0.9 between the relative fitness of C1C1 individuals is 1.0 and the relative fitness of C2C2 individuals is 0.8.
It is because there is no barrier to increasing the fitness of the more fit allele. The result of this is an increase in the fit alleles which is C1 here to reach equilibrium in the population.

This tutorial will take you step by step through the question. Individuals with the genotypes Aa Bb CC Dd and Aa bb Cc Dd are crossed. Alleles of these four genes assort independently of one another. Now you can use the step by step method to answer this challenging question. Give the proportion of the progeny of this cross that are expected to have each of the following genotypes. Please answer as a decimal.
a) Aa Bb Cc Dd
Number
b) aa bb CC DD
Number
c) Aa bb Cc DD
Number
Answer:
The correct answer is -
a) 1/16
b) 1/64
c) 1/32
Explanation:
According to the law of independent assortment, each allele of a particular gene has equal chances of getting inherited into the gametes.
In a Mendelian cross of Aa x Aa would give;
AA = 1/4,
Aa = 2/4 and
aa = 1/4
The result of the cross between AaBb x AaBb would be 1/16 due to the fact that probability is still the same AA = 1/4, BB = 1/4 therefore, AABB = 1/16 = 1/4× 1/4.
Now based on this crossing the following:
AaBbCCDd x AabbCcDd.
Take each allele as individual
Aa x Aa would give; AA = 1/4, Aa = 2/4 and aa = 1/4
Bb x bb would give; BB = 1/2, bb = 1/2
CC x Cc would give; CC = 1/2, Cc = 1/2
Dd x Dd would give; DD = 1/4, Dd = 2/4 and dd = 1/4
Then the probability of progeny of the following would be:
a) the probability of AaBbCcDd = 2/4 x 1/2 x 1/2 x 2/4 = 1/16
b) the probability of aabbCCdd = 1/4 x 1/2 x 1/2 x 1/4 = 1/64
c) the probability of AabbCcDD = 2/4 x 1/2 x 1/2 x 1/4 = 1/32
