Answer:
Enzymes work best and are more efficient at a certain temperature. This is called the 'optimum temperature'. This investigation was carried out at 40° as this temperature allows more collisions among the molecules, thus being the optimum temperature for enzyme activity.
Higher temperatures causes the enzymes to be denatured .

Explain how physical and chemical properties influence the formation of ocean current and the distribution of marine life
False answers will be reported but if your answer is good I will give it brainliest.
Answers
Physical and chemical properties influence the formation of ocean current and the distribution of marine life through the different features present.
What is Marine life?This is referred to as the animals, plants and other organisms which live in salt water sea and oceans.
Physical and chemical factors such as oxygen levels and light availability promotes the presence of of plants and animals as they are able to undergo photosynthesis and also respire thereby ensuring their increased growth and reproduction.
High ocean current also reduces the amount of organisms present in the marine life due to them being washed away to other parts and hindering their survival.

Okazaki fragments are formed on which strand?
Answers
Answer:
The leading strand is continuously synthesized and is elongated during this process to expose the template that is used for the lagging strand (Okazaki fragments). During the process of DNA replication, DNA and RNA primers are removed from the lagging strand of DNA to allow Okazaki fragments to bind to.

The honeybee has 32 chromosomes in their somatic cells. They undergo meiosis but can
produce offspring drones without fertilization. How many chromosomes does the drone have?
What does this mean for the drone?
Answers
Answer: 32 chromosomes, they are clones of the parent drone
Explanation:
The production of offspring drones without fertilization means that offspring that are produced are produced by mitosis, which results in daughter cells that are clones of the parent. They have the same amount of chromsomes as the parent drone, which is 32.

Are the corals on the Great Barrier Reef at high risk, moderate risk, or low risk of bleaching due to heat stress? Use the temperature data to explain your answer.
Answers
Answer:
Moderate risk.
Explanation:
Now, I would say between moderate and high but the bars are not all that high, but yes, the coral will be damaged by overbleaching caused by heat stress. The bars are above at minimum 21.77 degrees Celsius and a maximum of 31 degrees Celsius. Coming from a middle schooler, it sounds like a brainless answer. I hope you get it right
As per the given graph, the corals on Great Barrier Reef are at moderate risk of bleaching.
What is coral bleaching?When the water temperature rises too high, corals expel the algae (zooxanthellae) that live in their tissues, causing the coral to turn completely white.
This is known as coral bleaching. A coral that bleaches is not dead. Corals can survive a bleaching event, but they are stressed and may die as a result.
Bleached corals are more likely to have slower growth rates, lower reproductive capacity, increased disease susceptibility, and higher mortality rates.
When more vulnerable species are killed by bleaching events, the coral community composition can change.
When corals are exposed to high temperatures, they expel the microscopic algae that live within their tissues, revealing their white skeletons.
Although bleached corals are not dead, they are more vulnerable to starvation and disease.
Thus, as in the given graph, the temperature range is fluctuating but are higher than the threshold heat for corals, these are on moderate risk of bleaching.

Which of the following explains the role of plants in the carbon cycle?*
(1 Point)
Plants transfer oxygen and carbohydrates in the biosphere to carbon dioxide in the atmosphere.
Plants transport carbon dioxide in the atmosphere to groundwater.
Plants transfer carbon dioxide in the atmosphere to carbohydrates in the biosphere.
Plants transfer oxygen in the atmosphere to fossil fuels.
Answers
Answer:
Plants transfer carbon dioxide in the atmosphere to carbohydrates in the biosphere.
Explanation:
Plants are unique organisms being that they have the unique ability to manufacture their own food via the process of PHOTOSYNTHESIS. Hence, they are called AUTOTROPHIC. Photosynthesis is the metabolic process by which plant cells make sugar (glucose) in the presence of sunlight.
However, in the photosynthetic process, plants require inorganic source of carbon called CARBON DIOXIDE (CO2) and water to perform the process. The chemical overall reaction of photosynthesis is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
This explains the role of plants in the carbon cycle as they help transfer carbon dioxide (CO2) in the atmosphere to carbohydrates in the biosphere (living organisms).

The majority of supplements use lab-made cordyceps. Despite the fact that cordyceps is occasionally referred to as a mushroom, the form of cordyceps created in a lab does not grow a mushroom.
By stimulating immune system cells and certain molecules, cordyceps may enhance immunity. In especially with lung or skin malignancies, it may also aid in the fight against cancer cells and reduce tumor size. Natural cordyceps can be pricey and difficult to get.
