Answer:
Coral reefs are under threat if atmospheric carbon dioxide levels continue to rise, new research has shown. When CO2 dissolves in the ocean, it raises the water's acidity level. This prevents a build up of calcium carbonate, which corals draw from seawater to build their skeleton
Explanation:
If atmospheric carbon dioxide continues to rise it creates a threat condition to coral reefs to their skeletons.
What are coral reefs?According to recent research, coral reefs are in danger if atmospheric carbon dioxide levels keep rising. The ocean's water becomes more acidic as a result of CO₂ dissolving there.
This hinders the buildup of calcium carbonate, which corals use to create their skeleton from saltwater. More CO₂ is absorbed by the seas when CO₂ emissions rise.
The water is getting warmer as a result of increased greenhouse gas emissions. In water that is too much warmer or colder than 26–27 degrees celsius, coral cannot survive.
Therefore, as a result, coral has a tougher time developing its shells since the water becomes more acidic.

A student graphed distance versus time for an object that moves 14 m every 2 seconds. What is the slope of the ling on the graph. Please explain!
Answer:
A slope of 7, representing a speed 7 m/s.
Explanation:
Speed is defined as the distance traveled over time. Mathematically, it's calculated with the equation:
[tex]speed = \frac{distance}{time}[/tex]
Slope of a graph is the rate at which the y and x axis change together, the "rise over the run." Slope can be simply calculated using this equation:
[tex]slope = \frac{x_{2} - x_{1}}{y_{2} - y_{1}}[/tex]
Therefore, when graphing distance versus time, the change in distance is divided by the change in time to find the slope. This is the same as speed.

Use of the GAH may increase the amount of hormones in the milk.
C.
Use of the GAH may provide extra milk to feed the poor.
D.
Use of the GAH may allow the farmer to reduce milk prices.
Answer:
B
Explanation:
A farmer uses genetic engineering to inject dairy cows with a genetically altered hormone (GAH) to result in the production of more milk, and the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.
What is a genetically altered hormone(GAH)?The GAHs that are used in dairy farming can result in an increase in the levels of hormones such as insulin-like growth factor 1 (IGF-1) in the milk, and these hormones can be harmful to human health and are also associated with an increased risk of certain cancers, such as breast cancer and In addition to concerns about the health effects of GAHs, there are also environmental concerns. The increased milk production resulting from GAH use can lead to overproduction, and animals get harmed by these genetically altered hormones.
Hence, the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.

How are Earth's structures created over time?
Answer:
Earth crust is constantly changing primarily due to plate tectonics (plate motion), but it also changes from activity on the surface from river, man made and meteorite impact. ... Continents and oceans do not ride atop the plates without changing. As the plates move and change so do the continents and oceans
Answer:
Explanation:
Earth's structures were created when the planet was first formed. Over time, its own gravitational and magnetic forces drove the Earth's core rotation. Other geological activities affected its structures; such as glacial movements, tectonic plates collisions and submersion, volcanic eruptions and so on. There were also major external events the asteroid impact that killed most lives on Earth. Human activities' impact on Earth's structures were relatively small until the recent centuries.

Los procesos de respiración aerobia celular y fotosíntesis, procesos considerados indispensables para la vida en la tierra, de los que es correcto afirmar que Son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas. La respiración celular sólo la realizan los seres eucariotas del reino de los vegetales. Ambos son realizados por los seres considerados eucariotas. Ambos son realizados por eucariotas pertenecientes al reino de los vegetales
Respuesta:
Las opciones correctas son: a) son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas; y d) ambos son realizados por eucariotas pertenecientes al reino de los vegetales.
Explicación:
La fotosíntesis y la respiración celular son procesos de carácter antagónico porque la fotosíntesis es anabólica y la respiración celular es catabólica. La fotosíntesis consiste en la producción de moléculas complejas a partir de moléculas simples (proceso anabólico), mientras que en la respiración celular se degradan moléculas complejas y se las convierte en moléculas más simples (proceso catabólico).
Ambos procesos son realizados por los eucariotas del reino de los vegetales, pero los eucariotas del reino animal sólo realizan respiración celular, ya que no tienen cloroplastos. Esta diferencia tan importante existe porque los animales pueden moverse para conseguir comida (heterótrofos), mientras que los vegetales necesitan producir sus propios nutrientes haciendo uso de la fotosíntesis (autótrofos). Más allá de esta diversidad, todos los eucariotas realizan respiración celular para producir energía en forma de ATP.

Find the hypotenuse of a right triangle whose legs both have a length of 5.
Answer:
Hypotenuse = 7.07 units.
Explanation:
The sides of the right angle triangle are the opposite and adjacent side; which are both equal in this case.
Given the following data;
Opposite = 5 units
Adjacent = 5 units
To find the hypotenuse, we would use the Pythagorean theorem given by the formula;
Hypotenuse² = opposite² + adjacent²
Hypotenuse² = 5² + 5²
Hypotenuse² = 25 + 25
Hypotenuse² = 50
Hypotenuse = √50
Taking the square root of both sides, we have;
Hypotenuse = 7.07 units.

What causes stomach cramps?
Answer:
the main causes are, infection,abdominal growth,inflammation,obstruction blockages
Explanation:
“Stomach cramps” is a general term that refers to sharp, intermittent contractions or feelings of pain or discomfort that occur anywhere in the abdomen between the lower chest and the pelvis or groin. The abdomen consists of many organs, including the stomach, intestines, liver, gallbladder, pancreas, esophagus, and numerous blood vessels.
Stomach cramps are a common symptom of a wide variety of mild to serious diseases, disorders and conditions that are often related to the abdominal organs and sometimes the pelvic organs, such as the uterus and bladder. Most people will experience stomach cramps at some point during their lifetime, and they can occur in any age group or population. Common causes of stomach cramps include indigestion, gastroenteritis, menstrual cramps, bladder infection, and excessive flatulence (gas).
Stomach cramps may be generalized, which means they occur throughout the abdomen. Stomach cramps may also be localized in a small area of the belly, such as the lower abdomen or pelvis near the groin, or in the upper abdomen where the stomach is located.
Depending on the cause, stomach cramps can last for a few minutes or hours, such as when they occur from indigestion due to eating rich food or from vigorous exercise. Stomach cramps can also last for a few days, such as when they are due to a menstrual period. Long-term stomach cramping may be continuous or occur periodically and may be due to more serious conditions, such as colorectal cancer.
In some cases, stomach cramps may be caused by serious conditions, such as food poisoning or colorectal cancer. Seek prompt medical care if your stomach cramps are unexplained, persistent, or cause you concern.
Stomach cramps may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. If you have other symptoms along with stomach cramps, be sure to inform your health care provider. This information will help your doctor diagnose the reason for your stomach cramps.
