HELP!!! Coral bleaching events are occurring in coral reefs around the world. Which statement best describes how human activity will likely continue to cause a loss of reef biodiversity​

Answer:

The control group stays consistent throughout an experiment.

Explanation:

In an experiment, the basic format is to have two different groups, the independent group and the control group. You apply whatever change to the independent group, but keep the control group the same.

Independent group - the group that receives treatment.

Control group - the group that receives no change and is used as a comparison to the independent group.

For example:

Q: Shaun is doing an experiment. He wants to test whether sugar water makes lima beans grow faster. What would be his control group and his independent group?

A: His control group would be the lima beans that are only given regular water. His independent group would be the lima beans that are only given the sugar water, because that is the element he is trying to test.

Answer:

Option D

Explanation:

The DNA strands are composed of nucleotides which consists of sugar,  phosphate and nitrogenous bases. The base pairs of one DNA starnd bind to the base pair of other DNA strand. The nitrogenous bases in the two strands of  DNA make pairs such as A binds with T and C binds with G.

These base pairs are held together by the hydrogen bonds which are weak molecular forces.

Hence, option D is correct

Explanation:

Considering the size of 200µm and the absence of a nucleus, the sample observed under the microscope is most likely a bacterium as bacteria typically match these characteristics.

The sample you observed under the microscope is 200 µm in diameter and has no nucleus. Based on these observations, the sample is most likely a bacterium. Bacteria are typically around this size and lack a nucleus. In contrast, human red blood cells, which are also devoid of a nucleus, are about eight micrometers in diameter which is significantly smaller than 200 µm. Furthermore, the size of some other cellular organelles and viruses is also comparatively small. Therefore, considering the size and absence of nucleus, the most probable classification of the sample would be a bacterium. Micrographs obtained through different microscope types can aid us to observe and study such small entities.

Answer:

Two rocky material collision cause water formation

Explanation:

Earth is rich in water, and has been for a few billion years, but scientists are still debating just where all that life-sustaining liquid came from. At least some of it was thought to have been brought here by comets or asteroids, but that idea still falls short in explaining how so much water ended up on Earth’s surface – and deep below, as well. Now, a team of scientists at Arizona State University (ASU), led by Peter Buseck, has come up with a new proposal. The new peer-reviewed paper was published in the Journal of Geophysical Research: Planets on October 9, 2018.

The new research suggests that Earth’s water came from both rocky material, such as asteroids, and from the vast cloud of dust and gas remaining after the sun’s formation, called the solar nebula.

The 2019 lunar calendars are here! Order yours before they’re gone. Makes a great gift.

Earth’s ocean water is similar to that found in asteroids. That’s one reason scientists have long thought that most earthly water came from an asteroid bombardment in the days of the early solar system. The ratio of deuterium – a heavier hydrogen isotope – to normal hydrogen is a unique chemical signature in various water sources. In the case of Earth’s oceans, the deuterium-to-hydrogen ratio is close to what is found in asteroids. But, according to Steven Desch, also at ASU and one of the team members:

Answer:

Option (1)

Explanation:

Sound waves are produced due to the vibration of any particular object. These waves propagate freely in air. When these sound waves change its medium from air to water, which is a denser medium, then the velocity of these waves gradually decreases. It is because, in the denser medium, the materials are compressed tightly and the speed of the sound waves in water decreases with the increasing water depth.

Thus, when the sound wave travels from air to water, it gradually slows down.

Hence, the correct answer is option (1).

Answer:

a) when cells are small the movement of food and waste can be efficiently handled by the cell membrane

Explanation:

Cells need to get their nutrients and waste in and out of their cell membrane every quickly. Cells are hard workers anyway! The other options also don't make much sense. The cell shape doesn't mean much to their function, and size doesn't impact shape. The cell's internal parts (mitochondria, vacuole, etc) don't support the cell membrane, they have their own functions to focus on. Cells don't work together in tissue but they can interact with each other when needed.

Answer:

The statement (a) correctly describes that why cells are so small.

Explanation:

Cells are formed of cytoplasm enveloped by a phospholipid bilayer. In the cells of plants, a supplementary cell wall also prevails. The cytoplasm accommodates various metabolic activities that need a spontaneous supply of nutrients. During the same time, metabolic wastes originate from these reactions, which are required to be eradicated. All this uptake and discard of nutrients and waste components occurs by mediation across the cell membrane via passive, active, or facilitated transport.  

In the absence of any circulatory system, these cells depend entirely on the process of diffusion through the membrane. The brisk interchange of molecules can only take place if diffusion occurs over brief distances. Thus, this rate of uptake of nutrients within the cells and discarding of wastes into the external surroundings hugely relies upon the cell surface, which is restricted by the cell membrane. Thus, surface area of the cell is one of the limiting factors to monitor the rates of diffusion of these molecules. Therefore, when the cells are small, their wastes and food can be handled effectively by the cell membrane.

CORRECT ANSWER  ► B

B- A periodic warming sea surface temperatures

☺☺☺

El Niño is associated with a periodic warming of sea surface temperatures, which is part of the short-term, worldwide climate event known as the El Niño-Southern Oscillation (ENSO). Hence, the correct option is B.

El Niño is a short-term, worldwide climate change event marked by the warming of the Pacific Ocean. This is an aspect of the El Niño-Southern Oscillation (ENSO) that affects weather patterns around the globe. During El Niño, typical weather patterns are disrupted, leading to significant effects such as increased rainfall in normally dry regions and diminished fish populations due to the warmer, nutrient-poor waters.

Coastal upwelling normally brings cold, nutrient-rich waters to the surface, but this is inhibited during El Niño events, deepening the thermocline and preventing the normally productive waters from supporting large fish populations. Moreover, ENSO events have a cyclical nature, typically occurring every two to seven years and can influence global temperatures and precipitation patterns.

Answer:

The answer is: The first generation.

Explanation:

In genetics the allelic frequency or gene frequency is the proportion observed of a specific allele with respect to the set of those who can occupy a given locus in the population.

If the frequencies remain constant from one generation to the next, the population is not experiencing evolutionary change, and is said to be in gene equilibrium.

Mendel's first law: Law of the uniformity of the hybrids of the first generation, and says that when two varieties of purebred individuals are crossed, both homozygous, for a given character, all the hybrids of the first generation are equal.

Pyruvic acid enters the Karen's cycle and is first converted into acetyl CoA.

Karen's cycle

The Karen's cycle refers to the citric acid cycle which is a cycle that releases stored energy.

Pyruvic acid is transported into the mitochondria, where it is converted into acetyl CoA via the enzyme pyruvate dehydrogenase. This step precedes the Krebs cycle, where acetyl CoA is further broken down to generate energy.

Pyruvic acid enters the mitochondria and is first converted into acetyl CoA. This process occurs in the mitochondrial matrix where the enzyme pyruvate dehydrogenase catalyzes the conversion of pyruvate into acetyl CoA, releasing a molecule of carbon dioxide and forming NADH from NAD+ in a reaction known as oxidative decarboxylation. After its formation, acetyl CoA then enters the Krebs cycle, also known as the citric acid cycle or tricarboxylic acid (TCA) cycle, where it is metabolized to produce ATP, NADH, and FADH2.

The three-carbon pyruvate molecule generated during glycolysis moves from the cytoplasm into the mitochondrial matrix, where it is converted by the enzyme pyruvate dehydrogenase into a two-carbon acetyl Coenzyme A (acetyl CoA) molecule. This reaction is an oxidative decarboxylation reaction. It converts the three-carbon pyruvate into a two-carbon acetyl CoA molecule, releasing carbon dioxide and transferring two electrons that combine with NAD* to form NADH. Acetyl CoA enters the Krebs cycle by combining with a four-carbon molecule, oxaloacetate, to form the six-carbon molecule citrate, or citric acid, at the same time releasing the coenzyme A molecule.

Answer:

It decreases pH

Explanation:

Alveolar hyperventilation leads to a decreased partial pressure of arterial carbon dioxide (PaCO2). The decrease in bicarbonate is accompanied by the deviation of serum pH below 7.35.

It is called Respiratory Acidosis. It´s blood pH imbalances. Muscle fatigue is associated with a rapid increase in the production of metabolic acids. Tolerance to high intensity exercise may be limited by the body's ability to dampen the decrease in intracellular (muscle) and extracellular (blood) pH, that is, the intrinsic buffer system.
