Answers

Turtles will choke and the plastic will get caught in its throat and will die and you can stop this by stop polluting
The turtles will eat the bag leading to choking also leading to possible death unless treated right then. which is rare. you can stop hurting these innocent creatures by nonpolluting the environment.

With no herring to eat, how would the eating habits of cod change

Answers

Answer:

The answer is: Mackerels, perches, soles, eglefinos, mainly.

Explanation:  

The codis very voracious and all the prey that is within reach is good for him, even the juvenile cod. But his favorite delicacies are asmall squid, and thewavy bucino. In their early stages of life they feed onkrill, zooplankton and crustaceans, before moving on to small fish such aschaplain and herring, the adult eats other fish such asmackerels, perches, soles, eglefinos, mainly.

The answer is: Mackerels, perches, soles, eglefinos, mainly.

To prepare for the cross-country meet, a skier decides to significantly increase the amount of carbohydrates in his diet (a technique also known as carbohydrate loading). Why might this be beneficial to the cross-country skier? Check all that apply. Carbohydrates are used to build actin filaments in the myofibrils, which increases muscle bulk and performance. The liver can store copious amounts of ingested carbohydrates as glycogen, which can then be slowly broken down to release the glucose needed to fuel aerobic respiration. As long as oxygen is present, the glucose stored in the ingested carbohydrates can provide a steady stream of ATP, thus meeting the demands of prolonged periods of exercise. Eating more carbohydrates leads to more glycogen stores in muscles, which then equates to larger energy stores for short, explosive bouts of energy use.

Answers

Answer:

The glucose is the primary source of energy, which yields ATP in the presence of oxygen. The continuous intake of carbohydrates provide streamlined flow ATP that is meeting the demands of prolonged exercises.

Explanation:

Carbohydrate loading is defined as the increase in the intake of carbohydrates. Carbohydrates are stored in the form of glycogen, which is then broken down to yield glucose. Glucose is necessary to drive the vital functions of the body, such as respiration.

An athlete performing extensive exercise requires streamflow of ATP to fulfill the energy demands of the body. The metabolism of glucose provides ATP. The carbohydrates are the rich source of glucose, which in the substrate level undergoes oxidative phosphorylation and citric acid cycle. Oxygen plays a primary role in the breakdown of carbohydrates as glucose. It plays a crucial role in accepting electrons in the electron transport chain to synthesize ATP.

Thus, the continuous supply of oxygen is necessary for the metabolism of macromolecules. ATP in a higher amount is required by athletes to improve muscle performance. Thus, the stored glucose and continuous supply of oxygen are necessary to generate energy molecules.

Organic compounds do NOT contain which of the following?

Answers

Okay... glad you got it but it is good to share in case someone else needs that answer :)
In the 19th century is was assumed that organic compounds could only be produced by plants and animals. These compounds all had carbon and hydrogen in common. Some organic compounds also include O, N, the halogens, S and a few other elements.

Now we know that organic compounds can be synthesized in the laboratory. Simple compounds of carbon and hydrogen include the alkanes and alkenes, for instance, as well as aromatics like benzene. But oxygen is a common element in organic compounds like alcohols, aldehydes, ketones and ethers.

So the bottom line is that all organic compounds contain C and H and some contain O as well, but O is not required to be an organic compound.

========= Follow up ==========

Why are these people saying "yes". It's obvious that there are many organic compounds that don't contain oxygen

WILL MARK BRAINLIEST Scientists have been studying threats to coral reefs. The percent of reefs affected by various threats are shown in the figure below. A future global temperature increase may affect all categories on the figure. Predict which category would change the most from global temperature increases and propose a testable question that scientists could study.

a. The biggest effect will be on the far right column that includes thermal stress with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater fishing risk also have greater thermal risk.

b. The biggest effect will be on the far right column that includes thermal stress, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in watershed-based pollution.

c. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether increased fishing causes increased marine-based pollution.

d. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in fishing threats.

Answers

Coral reefs are the organisms of the aquatic ecosystem. The column includes the thermal stress that will be affected the most as the reefs fall into high and very high threats are huge. Thus, option B is correct.

What is the effect of thermal stress on coral reefs?

Due to an increase in pollution and global warming, the oceans have heated up, which results in thermal stress and leads to coral bleaching and threat to the coral reefs.

The percentage of the very highly threatened, highly threatened, slightly threatened, and threatened reefs are seen majorly due to the thermal stress. Thermal stress is in increases amount due to oceanic warm-ups.

The thermal stress due to increased carbon dioxide activities and acidity leads to coral bleaching causes the destruction of the reefs and their endangerment.

Therefore, option B. the far right column labeled thermal stress has the biggest effect on the coral reefs.

Answer:

It's B

Explanation:

Temperature rise will eventually end up putting coral reefs into the high threat categories, not fishing and DEFFINITELY not lowering their "risk" factor.
