Answer:
Do a literature search to find natural history information on closely related species.
Explanation:
In the context, few graduate students monitored the benthic organisms from the fresh lake water samples and identified the invertebrate species that are present.
They also discover a crustacean which appears to be the new species for which they decided to do a study on its natural history. The first thing that the graduate student should do is to do a literature search for finding a natural history on the information that are closely related species.

Explanation:
To test for protein, you added Biuret solution and observed color changes. Suppose that the color data below was observed.
A 3-column table has 1 rows. The first column is labeled Gelatin (+ control) with entry pink/purple. The second column is labeled
Water (negative control) with entry pink/purple. The third column is labeled Mystery food sample with entry blue.
The data above indicate an error. How do you know? What might have caused the error?
Answer:
When tested for proteins neither gelatin or water was not pink/purple
Explanation:
credit to person who commented on question above
Answer:
The water should not be pink/purple because water should test negative for protein. The water should actually have turned blue, because Biuret solution is blue. Someone may have mislabeled the test tube with water. The water may have been contaminated with a protein.
Deforestation occurs when large Amounts of trees are cut down and not replaced which of the following would result from deforestation
A. Decrease carbon in the atmosphere
B. Increased carbon in the atmosphere
Answer:
The correct answer is (B).
Explanation:
Deforestation occurs when large Amounts of trees are cut down and not replaced, which of the following would result from deforestation...
Increased carbon in the atmosphere
This statement is true because when trees become less abundant, the amount of oxygen being released into the atmosphere by trees via photosynthesis.
The circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.
What is Deforestation?Deforestation may be defined as the process of cutting down or eliminating trees in large numbers from our surroundings. This activity generally happens due to industrialization, wood extraction, urbanization, etc.
When the number of trees remains less in the environment due to deforestation or any other activity, the level of carbon dioxide in the atmosphere typically rises.
This is because carbon dioxide is considered the reactant of photosynthesis that is utilized by the plants along with water in the presence of sunlight and converted into oxygen.
But when the number of plants decreases, the level of carbon in the atmosphere increases, and the level of oxygen in the atmosphere decreases.
Therefore, the circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.

Why do many water animals not have a well developed blood system?
The simplest animals, such as the sponges (Porifera) and rotifers (Rotifera), do not need a circulatory system because diffusion allows adequate exchange of water, nutrients, and waste, as well as dissolved gases. Instead, gases, nutrients, and wastes are exchanged by diffusion.

Which type of vascular tissue is responsible for transporting water from the roots to the rest of the plant?
Answer:
Xylem tissue
Explanation:
Xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.
The diagram below represents the time a cell spends in the two main phases
of the cell cycle. In which phase does a cell spend less time?
A. Interphase
B. R phase
C. M phase
O
D. Prophase
The cell spends less time in the M phase, also known as the mitotic phase, where the actual division of the cell takes place.
What does happen during M phase?During this phase, the cell undergoes mitosis or meiosis, depending on the type of cell, resulting in the formation of two daughter cells. In contrast, the interphase is the longest phase of the cell cycle, where the cell grows and carries out its normal metabolic activities.
The R phase, also known as the S phase, is a sub-phase of interphase where DNA replication occurs. Prophase is the first phase of mitosis and is relatively short compared to the M phase as a whole.
During prophase, the chromosomes condense, the nuclear envelope breaks down, and the spindle fibers form. In metaphase, the chromosomes align at the metaphase plate.
During anaphase, the sister chromatids separate and move towards the opposite poles. Finally, during telophase, the spindle fibers disassemble, the nuclear envelope reforms, and cytokinesis occurs, resulting in the division of the cytoplasm and formation of two identical daughter cells.
In terms of the amount of time spent in each phase, interphase is the longest, accounting for about 90% of the cell cycle. M phase, on the other hand, is relatively short, accounting for only about 10% of the cell cycle. Therefore, a cell spends less time in M phase than in interphase.

a website that provides climate data for an area in a biome (for example, the city of Barrow, Alaska). Discuss how conditions in the biome affect the plant and animal life it contains.
Answer:
Greatly affected.
Explanation:
The conditions in the biome greatly affect the plant and animal life it contains because biome has a specific environmental conditions that allows specific organisms to survive and growth in that particular environment. A biome is a collection of plants and animals that have common characteristics for the environment in which they exist. In the cold regions, only those plants and animals survive and grow which has the adaptation and characteristics to that environment.

Tetrodotoxin is a potent toxin found in a variety of organisms including the pufferfish. The toxin binds to the extracellular side of the Na+ channel and prevents channel opening. This leads to paralysis of muscles, including the diaphragm. Death from respiratory failure can occur after ingestion of as little as 1 mg of the toxin. Why does this toxin cause paralysis? Question 7 options: The axon membranes become over-depolarized. The Na+ channels remain in the inactive, refractory state. The Na+ channel does not open wide enough to allow enough Na+ through the channel. The membrane depolarization is not amplified along the axon.
Answer:
The correct answer is - The membrane depolarization is not amplified along the axon.
Explanation:
Tetrodotoxin, a neurotoxin present in the liver and gonads of Marine organisms. it can inhibit the soidum channels which means it blocks the entering of the sodium in the cells or neurons if consumed it and it can lead to neurological and gastrointestinal disorders.
These toxins block the signals to move along the nerves to muscles In absence of sodium action potential cannot be sent along the axon by blocking the sodium channels. This results in weakening and paralysis.

Which of the following best describes the producers in a terrestrial food web?
A) They are at the top of the energy pyramid.
B) They obtain their energy from consumers.
C) They are unaffected by decomposers.
D) They convert energy from the sun to chemical energy.
Answer:
The correct answer is - D. They convert energy from the sun to chemical energy.
Explanation:
In any food web, producers are the organism that can make their own food and energy by converting light energy coming from the sun into chemical energy, this process called photosynthesis.
Normally producers are green plants. These are present at the bottom of the energy pyramid as these are the highest in the number. Consumers et energy from producers by feed on them.
