Explanation:

continual daylight

In the given image it is showing long days. The correct option is A.

The Earth orbits the sun once every 365 days and rotates once every 24 hours on its axis.

Day and night are caused by the Earth rotating on its axis rather than by its orbit around the sun.

The term "one day" refers to the time it takes the Earth to rotate once on its axis and includes both day and night time.

A day is roughly the time it takes for the Earth to rotate or for other large astronomical objects to rotate.

The number of daylight hours we have depends on our latitude and how the Earth orbits the sun.

The axis of rotation of the Earth is tilted relative to its orbital plane and always points in the same direction means toward the North Star.

Thus, the correct option is A.

Answer:

It's a non-polar covalent bond.

Explanation:

Non-polar means they do not interact with water. Carbon dioxide and Oxygen bonded together by sharing electrons equally.

In a typical animal, mitosis produces two identical daughter cells, while meiosis produces four unique daughter cells.

Meiosis is a type of cell division that involves the parent chromosome being halved and then divided again to form four unique daughter cells which have only one copy of chromosome from the parent.

This process occurs in sex cells such as the sperm and egg cells.

Mitosis is also a type of cell division but occurs with the parent cells to form two identical daughter cells.

This type of cell division have produces the same number of chromosomes the parents have and occurs in cells of the body which undergoes growth or during replacement of worn-out tissues.

Basically biology traces the study of the living world from ancient to modern times. Although the concept of biology as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to Ayurveda, ancient Egyptian medicine, and the works of Aristotle and Galen in the ancient Greco-Roman world. This ancient work was further developed in the Middle Ages by Muslim physicians and scholars such as Avicenna.

Sickle cell anemia is one of a group of disorders known as sickle cell disease. Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body. Normally, the flexible, round red blood cells move easily through blood vessels.

Explanation:

Based on "Sickle cell anemia is an inherited red blood cell disorder" taken from the text, I would say the correct answer is C, because it says "an inherited disorder" and describes Sickle cell anemia.

What are the two characteristics of Coelenterata?

Characteristics. All coelenterates are aquatic, mostly marine. The bodyform is radially symmetrical, diploblastic and does not have a coelom. The body has a single opening, the hypostome, surrounded by sensory tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey.

What are the two characteristics of Nematoda?

Their body is bilaterally symmetrical and triploblastic. They are cylindrical in shape. They exhibit tissue level organization. Their body has a cavity or pseudocoelom.

Explanation:

Answer:

When the oxygen level is low in a Purple Sea Urchin, muscles associated with Aristotle's Lantern pump fluid through its body (through the canals). Carbon dioxide (waste/not good stuff) is released through the anus. The Purple Sea Urchin obtains oxygen through diffusion only (the diffusion of oxygen into the organism).

Explanation:

Brainliest please

Sea urchins breathe through their feet tubes because of nonavailability of lungs and gills in them.  When the oxygen level is low at that time, the sea urchins pump fluids through their anus.

Sea urchins are able to survive in sea because of the tiny hair called spines  present on their body as  water currents are created because of the hair and waste gets washed away with the water currents created.

When the carbon dioxide level gets increased in the sea at that time the skeletal structures of the marine animals are also affected.

The shells made up of calcium also gets affected because of the increasing acidity in the water. Carbon dioxide not so good is released through the anus and  this totally affects the normal regulation of the creature.

Cellular respiration

Answer:

Cellular respiration

Explanation:

because it needs it to release energy from food for use by cells.

Answer:

it will disolve

Explanation:

Active transport occurs against the electrochemical gradient. It needs energy to move molecules from the lower concentration side to the higher concentration side. The mode of transport is active transport.

-------------------------------------------------

There are three main different types of transport across the membrane

Active transport is the transport of molecules that move against the electrochemical gradient, so it does need energy to happen.

Molecules move from the lower concentration side to the higher concentration side of the membrane.

Carrier proteins are in charge of active transport. The needed energy might proceed from the ATP molecules or the membrane's electric potential.

In the exposed example, a scientist wants to determine how substance L enters a cells in a culture.

Table 1. Rate of entry of substance L into mammalian cells in culture

External concentration of substance(mM)      Rate of entry of substance L

                     10                                                                     5%

                     20                                                                    25%

                     30                                                                    45%

                     40                                                                    65%

                     50                                                                     80%

                     60                                                                     90%

                     70                                                                      95%

                      80                                                                    100%

                      90                                                                    100%

                      100                                                                   100%

Now, we need to identify the most likely mode of transport across the membrane for substance L, and explain how information provided helps determine the most likely mode of transport.

We know that the intracellular concentration is 120mM.

As we can see, this concentration exceeds all of the culture media concentrations. Yet, the substance keep moving into the cell.

As the concentration inside the cell is always higher than the concentration outside, we can assume that this is not passive transport because the molecule transport is going against its concentration gradient.

Hence, the remaining option is active transport. And as said before, we can see it because the substance keeps crossing the membrane toward the cell interior despite its concentration being higher in the interior of the cell than in the exterior.
