Begin by selecting a freshwater or marine aquatic ecosystem as a model for your food web. Be specific. Choose a specific lake. Or, if you choose an ocean ecosystem, identify its geographical area and depth. Keep in mind that deep-sea organisms live in a completely different environment than surface aquatic organisms.
Next, conduct research on the following conditions in the ecosystem you chose. They influence the types of organisms that can live there.
geographical features
temperature
depth/light availability
salinity
pH
unique features that contribute to the ecosystem, such as other bodies of water that connect to it, unusual chemistry, and climate
Using the information you gathered, write a paragraph that describes conditions in the ecosystem.

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.

Is it good or bad to have exactly the same hereditary traits?
Answer:
Both
Explanation:
Well,it has both good and bad aspects.In my opinion,hereditary traits possess good side through the genetic factors whereas it shows negativity as it may cause some diseases or hard complications.
Answer:
Heredity is important to all living organisms as it determines which traits are passed from parent to child. Successful traits are more frequently passed along and over time can change a species. Changes in traits can allow organisms to adapt to specific environments for better rates of survival.

The following is a growth curve of bacteria. What type of growth curve is pictured? A) linear growth B) logistic growth C) exponential growth
Answer:
C) exponential growth
In the given figure, exponential growth curve is pictured.
What is exponential growth?It is the pattern of data, which demonstrates greater enhancements with passing time, giving rise to a curve of an exponential function. During the growth cycle of bacteria, the cells of bacteria goes through different phases, that is:
Lag phaseExponential phaseStationary phaseDeath phaseIn the case of bacteria, the cells enter the log or the exponential phase after the lag phase. This is the time when the cells get differentiate by the process of binary fission and double in numbers after each generation time.
In this pattern of growth, the metabolic activity is high as RNA, DNA, the components of the cell wall, and other substances essential for growth are generated for differentiation.
Thus, the pattern of growth demonstrated in the given figure is exponential growth.

Answer:
a. low diversity
Explanation:
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.
Explanation:
Compare and contrast the location and function of ribosomes in prokaryotic and eukaryotic cells.
Answer:
Explanation:
In eukaryotic cells, ribosomes are found in the cytosol of a cell, the mRNA , endoplasmic reticulum and also the matrix of the mitochondria. They are large molecules that catalyzes the synthesis of proteins, which is called translation. The ribosome choose tRNA and covalently links the amino acids into a polypeptide chain.
In prokaryotes, it can be found in cystosol and it help translate genetic code into protein.

A food web is more realistic because a snake
A. has multiple adaptations
B. eats more than just frogs
C. just feeds on birds
Answer:
B. eats more than just frogs
Explanation:
A food web is more realistic because a snake eats more than just frogs
A food web is more realistic because a snake eats more than just frogs. The correct option is B.
What is a food web?A food web is a network of interrelated food chains that represents the movement of materials and energy within an ecosystem. In a food chain, the various arrows symbolize the various species that are being consumed by one another and so represent the flow of energy. Additionally, it shows that an animal can eat a variety of foods.
Food chains that are linked together form food webs. In a food chain, arrows point from the organism being eaten to the organism eating it.
The energy flow in a food web is depicted by arrows. Food webs display every form of eating in an environment.
Thus, the correct option is B. eats more than just frogs.
