With global warming, icebergs are melting and releasing fresh water into the ocean. Draw what will happen to a fish in the ocean and label the hypotonic and hypertonic solutions.
Answers
With global warming and releasing fresh water into the ocean, a fish whose primary habitat is ocean will thrive well causing a reduction in fishes that lives in fresh water.
What is hypertonic and hypotonic solution?An hypertonic solution is a solution which has more solute than the cell causing water to flow out of the cell, thereby shrinking the cell.
On the other hand, an hypotonic solution has less solute and more water causing water to flow into the cells, thereby causing a swell in the cell.
Global warming changes the natural environment of organisms.
Therefore, fshes who lives in no freshwater may not survive when be fresh water is released into the ocean because of the concentration of salt.

The helper T cell is active when....
It has engulfed a pathogen
It has learned the shape of the antigen
It has made the MHC protein
Answers
T cells undergo a clonal expansion and differentiation followed by a contraction phase, once the pathogen has been cleared.
How does the T cell respond to a pathogen?Recent in vitro and in vivo evidence supports an antigen-pre-senting role for T cells. Human T cells exhibit major histocompatibility complex (MHC) class II antigens and adhesion molecules that are typical of antigen-presenting cells (APCs).
Controlling the populations of effector, memory, and naive T lymphocytes depends on cell survival and death. The presence of MHC proteins in the antigen-presenting cell is necessary for the identification process because they bind to these fragments, transport them to the cell surface, and present them to the T cells there together with a co-stimulatory signal.
Due to their dual specificity, T cells can distinguish between peptide antigens presented by self-MHC I or MHC II molecules and those presented by other MHC molecules.

How does respiration impact the amount of carbon in the atmosphere?
Answers
The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.
Study the reactions below:
1. PEP + ADP → Pyruvate + ATP ∆G = -14.8 kcal/mol
2. ATP + H2O → ADP + Pi ∆G = -7.3 kcal/mol
3. Glutamic acid + NH3 → Glutamine ∆G = +3.4 kcal/mol
Which reaction is non-spontaneous?
Answers
The spontaneity of a reaction is determined by the change in Gibbs free energy (∆G) of the reaction. If ∆G is negative, the reaction is spontaneous (i.e., it can occur without an external input of energy), whereas if ∆G is positive, the reaction is non-spontaneous (i.e., it requires an external input of energy to occur).
From the given reactions:
PEP + ADP → Pyruvate + ATP ∆G = -14.8 kcal/mol (Negative ∆G)ATP + H2O → ADP + Pi ∆G = -7.3 kcal/mol (Negative ∆G)Glutamic acid + NH3 → Glutamine ∆G = +3.4 kcal/mol (Positive ∆G)We see that reactions 1 and 2 both have negative ∆G values, indicating that they are spontaneous reactions. However, reaction 3 has a positive ∆G value, indicating that it is a non-spontaneous reaction.
Therefore, reaction 3 (Glutamic acid + NH3 → Glutamine) is the non-spontaneous reaction among the given reactions.

The number of decomposers would increase.
The number of primary consumers would increase.
The numbers of primary consumers would decrease.
Answers
If the wolf, snake, and hawk were removed from the food web, the numbers of primary consumers would decrease, as these predators play a crucial role in controlling the populations of primary consumers such as the grasshopper and squirrel. The correct answer is D.
The primary consumers in this food web are the grasshopper and squirrel. Since the grasshopper directly feeds on plants (producers) and the squirrel feeds on both plants and grasshoppers, the removal of the wolf, snake, and bird would eliminate the predation pressure on these primary consumers.
This would result in an increase in their population size.
Without the wolf, snake, and bird, the grasshopper population would likely experience less predation and competition, allowing their numbers to grow. As a result, there would be more grasshoppers available as a food source for the squirrel, enabling their population to increase as well.
The removal of the wolf, snake, and bird would not have a direct impact on the number of producers (plants) or decomposers (worms and mushrooms) in the food web.
However, indirectly, it may lead to changes in the population sizes of these organisms over time as the dynamics of the food web adjust to the absence of predators and their prey. Therefore, the correct answer is D.
