You know we have a ‘leap year’ every 4 years in February right? Make a guess- do you think these dates are exactly the same every year? *Explain completely*

Answers

Answer 1
These dates are not EXACTLY the same every year because each year starts off at a different day of the week, therefore, affecting the day February 29 will land on. This day is added to the calendar as a corrective measure since the Earth does not orbit the sun in precisely 365 days.

Who wants brainliest? Answer those 2 questions

Answer:

This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed: Example:  For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.

This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side: Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.

This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.

Genes help to define who an individual is inside and out. In addition to visible traits like weight and eye color, psychological qualities such as personality traits, intelligence, risk of mental illness, and more have been linked to genetics.

What is natural selection?

Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.

In this case, as it is a very dark forest, an animal with a white coat will attract more attention while an animal with a dark brown color will only be camouflaged in the environment.

One of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that, when placed in an aqueous solution, dissociates into a bicarbonate ion (HCO3-) and a hydrogen ion (H+).
Thus, H2CO3 = HCO3- + H+
If the pH of the blood increases, one would expect:

(A) a decrease in the concentration of HCO3- and an increase in the concentration of H+

(B) an increase in the concentration of H2CO3 and a decrease in the concentration of HCO3-

(C) a decrease in the concentration of H2CO3 and an increase in the concentration of HCO3-

(D) an increase in the concentration of HCO3- and a decrease in the concentration of OH-

(E) a decrease in the concentration of HCO3- and an increase in the concentration of both H2CO3 and H+.

I'm not sure if it is C or D ​

Answers

Answer:

The answer is "Option C".

Explanation:

In the given question, the pH scale is used to evaluate acid or basic (alkalinity) formulas. It is nearly positive throughout the blood. Human blood has to maintain its pH at about 7.4, to prevent dramatically increased or lower changes, even though the bloodstream enters or exits acidic or essential substances.  

The buffers are essential for stabilization management. Calcium carbonate produced as carbon dioxide joins the blood system and combines with the liquid is a buffer which adds to the pH level in the human blood. It is returned to the water and distributed as a waste product until it enters the lungs, that's why choice C is correct.

A non-polar fatty acids prevent cell membrane from dissolving in water. The correct option is A.

What is a cell membrane made of?

The cell membrane, also known as the plasma membrane, is uncovered in all cells and serves to separate the cell's interior from the outside environment.

The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.

These are glycerophospholipids, which are molecules made up of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon compound that serves as the membrane lipids' backbone.

As, these non-polar fatty acids are insoluble in water, so it protect the cell membrane from water. It actually prevent the cell membrane to get dissolve in the water.

Thus, the correct option is A.

Name and describe the five types of active transport systems.

Answers

Answer:

Please Mark as Brainliest. Please!!!!!!!!!!

Explanation:

Definition

Active transport is the process of transferring substances into, out of, and between cells, using energy. In some cases, the movement of substances can be accomplished by passive transport, which uses no energy. However, the cell often needs to transport materials against their concentration gradient. In these cases, active transport is required.

Active transport requires energy to move substances from a low concentration of that substance to a high concentration of that substance, in contrast with the process of osmosis. Active transport is most commonly accomplished by a transport protein that undergoes a change in shape when it binds with the cell’s “fuel,” a molecule called adenosine triphosphate (ATP).

For example, one type of active transport channel in the cell membrane will bind to the molecule it is supposed to transport – such as a sodium ion – and hold onto it until a molecule of ATP comes along and binds to the protein. The energy stored in ATP then allows the channel to change shape, spitting the sodium ion out on the opposite side of the cell membrane. This type of active transport directly uses ATP and is called “primary” active transport.

Another type of active transport is “secondary” active transport. In this type of active transport, the protein pump does not use ATP itself, but the cell must utilize ATP in order to keep it functioning. This will be explained in more depth in the section on Symport Pumps below.

Lastly, active transport can be accomplished through processes called endocytosis and exocytosis. In exocytosis, a cell moves something outside of itself in large quantities by wrapping it in a membrane called a vesicle and “spitting out” the vesicle. In endocytosis, a cell “eats” something by wrapping and re-forming its membrane around the substance or item.

Each type of active transport is explained in more detail below.

Types of Active Transport

Antiport Pumps

Antiport pumps as an example of active transport

Active transport by antiport pumps

Antiport pumps are a type of transmembrane co-transporter protein. They pump one substance in one direction, while transporting another substance in the opposite direction. These pumps are extremely efficient because many of them can use one ATP molecule to fuel these two different tasks.

One important type of antiport pump is the sodium-potassium pump, which is discussed in more detail under “Examples of Active Transport.”

Symport Pumps

Symport pumps take advantage of diffusion gradients to move substances. Diffusion gradients are differences in concentration that cause substances to naturally move from areas of high to low concentration.

In the case of a symport pump, a substance that “wants” to move from an area of high concentration to low concentration down its concentration gradient is used to “carry” another substance against its concentration gradient.

One example of a symport pump – that of the sodium-glucose transport protein – is discussed below under “Examples of Active Transport.”

Sympoter pump as an example of active transport

Active transport by symporter pumps

Endocytosis

In the third type of active transport, large items, or large amounts of extracellular fluid, may be taken into a cell through the process of endocytosis.

Hypothesis is a written observation, that has not been proven correct, but is written after observation of a specimen. Proving this particular hypothesis, shows the interconnectivity/ relationship between a hypothesis and a theory.

Explanation:

Simply put, a hypothesis is a written observation, which may or may not be true, while a theory is established when a hypothesis is proven correct.

AN EXAMPLE OF SOMETHING THAT COULD MAKE A THEORY TO BE REVISED:

If other laws or theories put before it controversies it.If its observations where not correctly written.If it cannot stand the test of time.If further experiments doesn't show the same result.

Hypothesis is  either written or evidence based observation but it has to be proven where as when a hypothesis is proved by doing experiments multiple times and getting same results then it is called as as scientific theory.  

What is scientific theory ?

scientific theory can be  a structured form where a group of facts can meet and  be explained by using scientific hypothesis and laws, each theory can be proved by doing experiments and applying scientific method.

Scientist will design an experiment and conduct the experiment to test  and prove that hypothesis; If the result of hypothesis is incorrect, then new hypothesis will be set and new experiment will begin.

If the result of  hypothesis is correct, repeated tests  have been done to ensure the accuracy of the result.

Mr. Chavez wants his class to prepare a procedure that would demonstrate cellular diffusion. Which of the following procedures would best demonstrate cellular osmosis?

A. A procedure that uses the skins of potato left overnight in oil

B. A procedure that uses a cluster of grapes left overnight in a high concentration of salt water
C. A procedure that uses a 2-liter bottle filled with oil and water and left overnight

D.A procedure that uses a banana that has been left overnight in milk

Answers

Answer:

B

Explanation:

The second option correctly shows the process of cellular osmosis.

When the grapes would be immersed in water, the molecules of water move across the cell membrane from the region of low to high solute concentration. Due to this, the water would leave the cells and diffusion of water from the cells of the grapes. Thus, option B is the correct answer.

In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).

Osmosis refers to the movement of a solution (often water) across a selectively permeable membrane.

This movement (osmosis) is due to the difference in solute concentrations on both sides of the semipermeable membrane.

In osmosis, water molecules move from a region of low concentration of solutes (e.g., salt) to a region of high concentration of solutes.

In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).

The second generation results in TT, Tt, Tt, tt.

TT is a tall Offspring.

Tt is a Tall Offspring, with a small t as a recessive trait.

tt is a short offspring because both the recessive traits (t) are together.

We can rule out option C.
