Explanation:

Answer:

Biologists believe that new species evolve from existing species by a process called natural selection. ... Organisms that inherit that favorable new gene are likely to become more abundant than others of the species. Sometimes the population of a species becomes separated into two areas, by geography or by climate.

Answer:

P wave and R wave

Atrial contraction = P wave

Ventricular contraction = R wave

Explanation:

The behavior of the frog heart from force recording  can be classified into ; P wave and R wave.

utilizing the ECG ( Electrocardiogram) data the aspect of the force recording that is due to atrial contractions is the ; P wave while the force recording that is due to ventricular contractions is the ; R wave  the ventricular contractions is also known as QRS

ECG is used to record the electrical activities of a heart at rest

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:

c. they can reach thousands of kilometers into the sun's atmosphere

Explanation:

A planet can be defined as a large celestial body having sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium), revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.

Basically, the planets are divided into two (2) main categories and these includes;

I. Inner planets: these planets are the closest to the sun and comprises of mercury, venus, earth and mars.

II. Outer planets: these planets are beyond the asteroid belt and comprises of jupiter, saturn, uranus and neptune, from left to right of the solar system. These outer planets are made mostly of gases (hydrogen and helium) causing them to be less dense than the solid inner planets.

A solar prominence is also known as filament and it can be defined as a large, bright, dense cloud of luminous ionized gas such as hydrogen, sodium calcium, etc., that erupts (extends) from the surface of the sun. It can linger in the corona for a very long time, reaching hundreds of thousands of kilometers into the sun's atmosphere (space).

Hence, the statement about solar prominences which is true is that, they can reach thousands of kilometers into the sun's atmosphere.

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

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.

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:

peptide antigens by MHC class II molecules

Explanation:

Helper T cells are activated by peptide antigens by MHC class II molecules. These antigens express on the surface of antigen-presenting cells (APCs). After activation, the T helper cells divide and secrete cytokines  to assist the immune response.

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.

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.

Answer:

- The ras proto-oncogene is converted into an oncogene

- Specific transcription factors are activated by phosphorylation

- Abnormally rapid cell growth and proliferation is induced

Explanation:

The Ras genes are proto-oncogenes, i.e., genes with oncogenic potential that may induce cancer. These genes (Ras) encode GTPase proteins involved in transducing survival and growth signals. When Ras genes suffer mutations, the resulting Ras proteins may remain in an active state that prevents the hydrolysis of GTP, thereby the Ras pathway remains constitutively activated. In consequence, mutated Ras genes function as oncogenes by constitutively activating MAP kinases which in turn activate transcription factors that control the expression of target genes involved in critical cellular processes and whose expression is associated with cancer-specific events (eg., increased angiogenesis, increased cell proliferation, reduced apoptosis, etc).

Answer:

through cell division :)

Explanation:

Genetic recombination occurs due to the crossing over event that takes place during meiosis. It occurs in the animals that reproduce by fusion of gametes, i.e., option C.

Genetic recombination is the formation of new genetic sequences as a result of crossing over.

It takes place in the germ cells forming gametes, which is the main reason behind variation.

Thus, the correct option is C.

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.
