Answer:

d

Explanation:

because

Answer:

it is 6% higher than the theoretical probability.

Explanation:

we start with out experimental.

84 times heads out of 150.

84/150 = 56.

=56%

now for theoretical.

since there are 2 sides, there are 2 chances of randomly getting heads.

1/2 = 50%

56% > 50%

therefore your answer is that it is 6% higher. hope my explanation helps!

Answer:

A The gravity of the moon pulls the ocean, which causes the tides.

Explanation:

Well all of the other answers are just completely different.

if the moon is invisible tides cannot be seen, but why is it at night it is called high tide. B is very odd because many surfing events happen during the day.

It is A because it contains the most context, because it is the only reliable and realistic option, because when the moon is up, and the sun is down, it causes stronger waves

C.Engulfing a foreign pathogen

Explanation:

Phagocytosis is a critical part of the immune system.

Several types of cells of the immune system perform phagocytosis, such as neutrophils, macrophages, dendritic cells, and B lymphocytes.

The act of phagocytizing pathogenic or foreign particles allows cells of the immune system to know what they are fighting against.

Question:

Imagine that you're an endocrinologist and a patient visits you because they constantly feel restless. You notice that they have a high heart rate and high blood pressure, even at rest.

Which of the following statements best describes a possible diagnosis to explain these symptoms?

Answer: CORRECT (SELECTED)

The patient is experiencing an issue with their adrenal glands, causing a hyper-secretion (over-secretion) of adrenaline hormone.

Explanation:

Normally, the "fight-or-flight" response only occurs at times of emergency. Because this patient is experiencing symptoms of the "fight-or-flight" constantly, they have too much adrenaline in their body due to hyper-secretion from adrenal glands.

Answer:

a. NADH

b. Ubiquinone

c. Cytochrome c

d. Oxygen

e. F0 subunit  

f. F1 subunit  

Explanation:

Electrons enter the Electron Transport Chain (ETC) from Nicotinamide Adenine Dinucleotide (NADH), which is an electron donor generated during different catabolic reactions (e.g., glucose oxidation). Ubiquinone or 'Coenzyme Q' is an electron acceptor that accepts electrons from both Complex I and Complex II and donates electrons to Complex III. The oxygen (O) is the final electron acceptor that accepts the electrons after they have passed through the ETC and ATPase. Complex III (also known as Ubiquinol-cytochrome c oxidoreductase) catalyzes the electron transfer from ubiquinol to Cytochrome c, which is coupled to proton translocation across the membrane. The F0 subunit of the ATP synthase forms a channel (embedded in the mitochondrial membrane) through which protons can flow. Moreover, the F1 subunit of the ATP synthase uses the energy released by the proton electrochemical gradient to drive the synthesis of ATP.

Answer:

Option A, It makes them less dense than water, thus aiding in buoyancy

Explanation:

Lipids stored with in the body of planktons make them capable to float in water against the buoyancy force of water in the down ward direction by reducing the overall density of the planktons. Hence, option A is correct

Answer:

Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators. For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms.

quantity of the substance remaining = initial quantity of the substance * (.5)^(time elapsed/half life of the substance)

2.50 = 20 * (.5)^(19.2/x)

The half-life period of the given sample of the radioisotope is equal to 6.41 hours.

The half-life of a radioactive substance is defined as the time that is required to reduce the original quantity of a radioactive element to half after decay.

Half-life of a radioactive element is the characteristic of the element and does not depend upon the initial amount of the radioactive substance.

Given, the original amount of the radioisotope, N₀ = 20.0 g

The remaining amount of the radioisotope, N = 2.50 g

The time for which decay occurs, t = 19.2 hours

Consider that k is the rate constant of the decay of radioisotope,

[tex]k =\frac{2.303}{t} \times log \frac{N_0}{N}[/tex]

[tex]k =\frac{2.303}{19.2} log \frac{20}{2.50}[/tex]

k = 0.108 hr⁻¹

The half-life time of radioisotope can be calculated from the below mentioned formula:

[tex]t_{\frac{1}{2}} =\frac{0.693}{k}[/tex]

[tex]t_{\frac{1}{2}} =\frac{0.693}{0.108}[/tex]

[tex]t_{\frac{1}{2}} =6.41 hrs[/tex]

Therefore, the half-life period of the given sample of the radioisotope will be to 6.41 hours.

Answer:

b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails

Explanation:

B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.

The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.

The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.

Answer:

Erythrocyte

Explanation:

Erythrocytes, or otherwise called, red-blood cells are responsible for transporting oxygen and carbon dioxide to and from the cells and tissues. The reason for this is because of a protein called hemoglobin. The hemoglobin found in erythrocytes allow for transportation of oxygen + CO2 to and from cells.

The circulatory system is responsible for carrying oxygen to cells and tissues is erythrocyte. Thus,  option "C" is correct.

Answer:

A.

Explanation:

Answer:

There will be more yellow-colored frogs in the population than red-colored frogs

Explanation:

Available data:

Number of snake attacks             Frog color

145 Approx                                          Green

180 Approx                                          Blue

125 Approx                                          Yellow

145 Approx                                          Red

The phenotype of individuals and the environment where they live, interact and determines the genes´ destiny in space and time. The result of this interaction and the gene destiny is Natural Selection. Natural selection selects beneficial alleles and increases their frequency in the population.

The attack by snakes is acting as a selective pressure on the frogs´ population. It is an ecological pressure that is modeling the frogs´ phenotype.

Animals that suffer more attacks are the blue ones, followed by green and red frogs. Those that suffer the fewest number of attacks are the yellow individuals.

So natural selection will be acting on this population favoring the alleles that code for yellow color. Genes that express yellow color increase more the frogs´ fitness than genes that code for the other colors. So natural selection increases the frequency of genes coding for yellow color and will decrease the frequency of the other alleles. Probably the less favored will be genes that express blue.

C. It prevents animals from catching prey or escaping predators is the correct option.

Noise pollution also understood as environmental noise or sound pollution, exists as the propagation of noise with ranging consequences on the activity of human or animal life, most of them detrimental to a degree. The source of outdoor noise worldwide exists mainly caused by machines, transport, and propagation techniques.

Noise pollution also understood as environmental noise exists as the propagation of potentially “damaging” sounds via the environment. The impacts of noise pollution tend to be seen as a nuisance rather than an environmental concern for decades.

Noise pollution harm wildlife by preventing  animals from catching prey or escaping predators.Due to noise pollution the prey organisms do not come out from their habitat. It becomes difficult for the predator to catch their prey if they do not comes out. Also prey organisms  gets frightened and fails to escape from their predators.
