II. Gender imbalances
III. Increased reproduction rates

The release of toxins such as heavy metals into the water bodies has been deeply frowned at .This is because toxins usually have a negative effect on aquatic species. The negative effects include:
Developmental dysfunctionGender imbalancesToxins also gives rise to developmental dysfunction in the animals . The toxins ensures that there is a shortage by interfering/reacting with the nutrient needed for the growth of these organisms.
The issue of gender imbalance is also true as some toxins causes water bodies to be warmer which favors the presence of female aquatic species such as reef fish.
Toxins causes aquatic bodies to be short of oxygen supply as the elements or compounds released vie for oxygen with the animals which may lead to less reproduction rates and death in severe occasions.

Explain how a lack of carbohydrates will impact cellular functions and why?
Answer:
Carbohydrates they say is the major classes of food and don't forget they are stored by stach in the body and gives your body energy
Carbohydrates are degraded into sugar which, as a primary source, is required for the brain, muscles and other parts of the human body to function normally.
When you don't get enough carbohydrates, the level of sugar in your blood may drop to below the normal range (70-99 mg/dL), causing hypoglycemia.

Answer:
i think that the higher the body temperature the higher the cellular respiration
Explanation:
The graph indicates the relationship between body temperature and cellular respiration. As the body temperature increases, more ATP is produced, but after a certain temperature, there is no cellular respiration.
What is cellular respiration?In cellular respiration, the cell breaks down glucose and forms ATP. Glucose is broken down by glycolysis, the Krebs cycle, the electron transport chain, and finally ATP is formed.
In the graph, it is shown that an increase in body temperature is related to an increase in ATP molecule production. ATP molecule production is nearly zero at 80 degrees body temperature. As the temperature increases to 100 degrees, ATP production increases to nearly 50.
After 100 degrees, the body temperature rises, but there is a decrease in ATP production. After 100 degrees, the enzymes required for cellular respiration don't work. Hence, a decline in ATP is seen.
Hence, after a certain temperature, the enzymes involved in cellular respiration don't function as their structure changes.

Enzyme activity generally increases as temperature increases within an enzyme’s optimal range because an increase in temperature causes an increase in molecular motion. This increase in molecular motion results in the enzyme and its substrate coming into contact with each other more often. At too high a temperature, however, the enzyme will become denatured and no longer be able to function. As the video describes, that is what happens when someone has a high fever.
What do you think happens to enzyme activity as temperature decreases outside an enzyme’s optimal range? Explain your answer in terms of molecular motion.
This most reliable temperature is commonly around human frame temperature (37.5 °C) for the enzymes in human cells. Above this temperature, the enzyme shape begins to interrupt down denature given that at better temperatures intra- and intermolecular bonds are broken because of the enzyme molecules' advantage of even greater kinetic electricity.
Each enzyme has a temperature variety in which a maximal charge of response is accomplished. This maximum is referred to as the temperature most desirable of the enzyme. The most excellent temperature for maximum enzymes is set at ninety-eight. 6 tiers Fahrenheit (37 ranges Celsius). There also are enzymes that work nicely at decreased and better temperatures.
Most activity is accomplished on the enzyme's ultimate temperature. The lively website online of the enzyme modifications shape as the temperature rises above the surest temperature, resulting in a decline in interest. Above and under the highest quality temperature, activity decreases.
Most enzyme functions are done at 37∘C in humans due to the fact the enzymes are capable of holding their structure at that temperature, allowing it to break down complex molecules efficiently.

Black fur (B) is dominant to white fur. Soft fur (S) is dominant to rough fur. What is probability that the
offspring will have white color and rough fur?
Answer:
A) 1/16
Explanation:
Because both white fur and rough fur are recessive traits, you need all genes shown to also be recessive. If a single trait is dominant, then it will be expressed instead of a recessive gene. Because there is only one square out of sixteen that is all lowercase, the chance of having both recessive traits (White fur and Rough fur) is 1/16.
HELP PLEASE!!!explain how Earth is heated through conduction
As it's known conduction needs a medium for heat transfer and during the day, sunlight rays pass through the Earth's atmosphere and near the earth's surface is where most heat transfer by conduction occurs since air is a poor conductor. Thus, the sunlight hits the earth's surface(ground) and in turn heats the air above it and transfering the heat.
It must be known that conduction happens mostly near the earth's surface.
Answer:
Conduction is one of the ways that energy is transferred from the earth's atmosphere to the air. Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules. Think of a frying pan set over an open camp stove.

energy. What did the wise wizard mean?
Answer: in humans, we don't use light energy to make ATP but in plants however, they create ATP in a proccess called photosynthesis, this process requires light to be absorbed twice, once in each photosystem, and it makes ATP. In fact, it's called photophosphorylation because it involves using light energy (photo) to make ATP from ADP (phosphorylation)

Imagine you have been shipwrecked and are floating on a small piece of wood in the middle of the ocean. You are terribly thirsty and take a drink of seawater (3.5% salt). What do you think happens to your stomach cells (1% salt), and why?
Given the higher salinity of the ocean water in comparison to your stomach cells, you will lose water from your cells and become dehydrated.
Osmosis is a phenomenon that shows that in the presence of a space in which the solute concentration is higher than its current location, water will travel towards that more concentrated space in an attempt to dilute the concentration.
The urge to drink is what we call being thirsty. This urge has a biological origin. It is the body's way of telling you that your cells need more water, which leads us to often consume any water we have available. This is not always in our best interest.
However, due to osmosis, drinking the seawater would only have a negative effect on your stomach cells. As stated in the question, the cells contain less concentration of solute (in this case salt) than the water. This means that instead of entering the cell, water would leave to dilute the new seawater, thus dehydrating you more and worsening your condition.
