Explanation:
Once the light organ is colonized, the squid no longer takes in Vibrio fischeri or other bacteria from the environment. Explain how a sufficiently large population of bacteria can be maintained in the light organ to produce light.
Answer:
Due to suitable conditions.
Explanation:
Large population of bacteria can be maintained in the light organ to produce light by providing suitable conditions for growth and development in the organ. The luminescent genes are off when the organ has low cell density while on the other hand, when the density of cell is high in the light organ the luminescent genes automatically turned on and light up the organ. These Vibrio fischeri needs habitat and food for their growth and survival which is provided by the squid. If there is sufficient food for the squid, the population of Vibrio fischeri increases in the light organ.

Why are sea otters considered a keystone species? Why are they important?
because of the crucial ecological role they play in maintaining the health and stability of the nearshore marine ecosystem. It is important because without sea otters,sea urchins can overpopulate the sea floor and devour the kelp forest that provide cover and food for many other marine.
Which type of mutation will affect the largest number of proteins produced by
an organism?
O A. Point mutation
B. Chromosomal mutation
C. Silent mutation
D. Missense mutation
SUBMIT
Answer:
chromosomal Mutation
Explanation: because the answer is B
The type of mutation will affect the largest number of proteins produced by an organism is Missense mutation. Thus, option D is correct.
What happens in sickle cell anemia?In sickle cell anemia, a change in the DNA nucleotide sequence is observed, where adenine is substituted by thymine, whose expression is the change in the sequence of amino acids in β-globin, with valine being incorporated instead of glutamic acid. This constitutes a mutation of the missense type.
Missense mutations are characterized by the substitution of one nucleotide by another in the DNA sequence —a point mutation— whose consequence is reflected in the transcription and substitution of one amino acid by another in a protein, whose structure or function will be altered.
The change from glutamic acid to valine in β-globin causes an altered hemoglobin, giving the abnormal erythrocytes observed in sickle cell disease.
Therefore, the type of mutation will affect the largest number of proteins produced by an organism is Missense mutation. Thus, option D is correct.

Your friend claims that all mutations are harmful to living things. Do you agree or disagree with this claim?
Support your position with:
a description of a genetic mutation and
a scientific explanation of how a mutation may affect an organism such as a tomato, spinach, or strawberry plant.
Answer: No, I do not agree with this claim. Genetic Mutations are changes in the genetic sequence, and they are a main cause of diversity among organisms. In other words, it is any change in the form of DNA. A mutation can result in a beneficial, neutral, or harmful reaction. It is mostly dependent on the organisms location and the context of the organism.

6. The cells produced via meiosis are called:
O a) sex cells
I b) somatic cells
O c) body cells
0 d) skin cells
The cells produced via meiosis are called gamete cells, such as sperm cells or egg cells. Hence option a is correct.
What is meiosis ?In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body or somatic cells in humans are diploid, meaning they have two sets of chromosomes one from each parent.
The egg and sperm that combine during fertilizations must be haploid, or having just one pair of chromosomes, in order to sustain this condition. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.
Meiosis is characterized by DNA replication, two rounds of cell division, and the production of four daughter cells, each of which has half as many chromosomes as the parent cell. Meiosis I and Meiosis II are the names of the two meiotic divisions.
Each chromosome's DNA is copied during the S phase of the cell cycle, resulting in two identical sister chromatids that are kept together by sister chromatid cohesion before meiosis starts.

Is this correct if not what is correct answer
Answer:
C. Matter is cycled through within an ecosystem, and energy at each trophic level is changed to heat energy.
Explanation:
An ecosystem can be defined as the natural living habitats of both living and non-living organisms. Essential services such as plant pollination, water purification, nutrient cycling, etc., that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.
Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy, heat energy, etc.
During cellular respiration, living organisms use organic matter which are transformed back to carbon dioxide, minerals and water while heat is transferred.
Hence, the response which best describes how matter and energy is cycled through the ecosystem is that; matter is cycled through within an ecosystem, and energy at each trophic level is changed to heat energy.

Answer:
Nucleotide sequence: ATG-GGG-CTC-AGC-GAC
Translation: Methionine-Glycine-Leucine-Serine-Aspartic acid (abbreviation: MGLSD)
Explanation:
The genetic code refers to the universal rules by which cells decodes information encoded within genetic material, either DNA or the resulting messenger RNA (mRNA), into proteins. In the genetic code, each triplet of nucleotide bases or 'codon' in the DNA/RNA sequence determines a specific amino acid in the protein. The AUG codon in mRNA is a start codon that specifies Methionine (M) amino acid, while UAG, UAA, and UGA are stop codons that determine the end of the protein.
How would the finch populations on these islands change over time?
The finch population's beaks will be modified; on dry islands, they will have larger beaks, while on rainy islands, they will prefer medium or short beaks.
What is natural selection?Natural selection is an evolutionary mechanism. Organisms that are better adapted to their surroundings are more likely to survive and pass on the genes that helped them thrive. Species change and diverge as a result of this process.
Because of the differences in environmental conditions, the finch populations on the dry and wet islands are likely to change differently over time.
Finches with traits that allow them to efficiently extract nutrients from dry seeds would have an advantage on the dry island, where food and water resources are limited.
Natural selection would favour these traits over time, increasing the frequency of these advantageous traits within the dry island finch population.
Thus, this way, the finch populations on these islands change over time.
