Anyone know????????????

Answer:

F. Both regulation and secretion

Explanation:

Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.

The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.

Red blood cells: Red blood cells (RBCs, also called erythrocytes; say: ih-RITH-ruh-sytes) are shaped like slightly indented, flattened disks. RBCs contain hemoglobin (say: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs.

Answer:

Thinking of a single plant as a plant system reminds us of the complexity of plant life

Explanation:

A plant system is a plant and all of its parts. This lets us know that there is an entire system within each plant, allowing it to carry out functions and live. We often take for granted the complexity of lifeforms, especially plants.

Have a great day

Answer:

There is a great interaction between reproductive stage and absorption of nutrients.

Explanation:

Good interaction of reproductive stage and absorption of nutrients from the soil is very important for producing good and healthy flowers because reproductive stage needs nutrients. If these nutrients can't available in the soil so the plant produced less flowers and as a result less seeds are produced in the end of this reproductive stage so we can say that reproductive stage and absorption of nutrients has a great interaction between each other.

Here is some info from the red cross...Universal donors are those with an O negative blood type.  Why?  O negative blood can be used in transfusions for any blood type.  

Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants.

Approximately 45 percent of Caucasians are type O (positive or negative), but 51 percent of African-Americans and 57 percent of Hispanics are type O. Minority and diverse populations, therefore, play a critical role in meeting the constant need for blood.

Types O negative and O positive are in high demand.  Only 7% of the population are O negative. However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population).

The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood. For more about plasma donation, visit the plasma donation facts. There are very specific ways in which blood types must be matched for a safe transfusion. The right blood transfusion can mean the difference between life and death.

Every 2 seconds someone in the US needs a blood transfusion.

Use the interactive graphic below to learn more about matching blood types for transfusions.

Also, Rh-negative blood is given to Rh-negative patients, and Rh-positive or Rh-negative blood may be given to Rh-positive patients. The rules for plasma are the reverse.

Answer: The term epigenome is derived from the Greek word epi, meaning above the genome. The epigenome consists of chemical compounds that modify or mark the genome in a way that alters the instructions given by the DNA.

Answer: The endosymbiotic theory suggests that eukaryotic organisms evolve from primitive prokaryotic organisms.

Explanation:

According to the endosymbiotic theory the organelles like mitochondria and chloroplast in the eukaryotic cells have arisen from aerobic bacteria. The aerobic bacteria being prokaryotic cell was consumed by the anaerobic bacteria or prokaryotic cell.

The following are the evidences of the origin of eukaryotic organisms from prokaryotic organisms:

1. The chloroplast and mitochondria have circular DNA like bacteria.

2. The mitochondria and chloroplast reproduce through binary fission which also occurs in bacteria.

Answer:

The Endosymbiotic Theory states that the mitochondrion and chloroplasts were consumed by a cell and now depend on one another to survive. Endosymbiotic Theory helps us by giving us the technology to use forensic sciences to solve cold cases.

Answer:

North Pole

Explanation:

The surface of the Earth is inclined perpendicular to the sunlight (as in the left hand side of figure 2), and so receives the maximum amount of sunlight per square area. The situation is most extreme at the north and south poles. At the north pole, the season is one long,cold night which last for six months.

Answer: There are actually three, Kepler's laws that is, of planetary motion: 1) every planet's orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet's orbital period is proportional to the cube of the semi-major axis of its

Explanation:

7.5% of 217 = 16.275

At end of 1 year bisons = 217 - 16.275 = 200.725

7.5% of 200.725 = 15.054375

At end of 2 years bisons = 200.725 - 15.054375 = 185.670625 (Rounding that to the tens)

=186

Explanation:

Answer:

42. Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine

Explanation:

43.Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.

44.polymer of nucleic acid

33 terms. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Threose nucleic acid (TNA) is an artificial genetic polymer in which the natural five-carbon ribose sugar found in RNA has been replaced by an unnatural four-carbon threose sugar.

Not only is the biota important, but the abiotic factors in the ocean are also important because both groups work together. The abiotic factors in the ocean help the ocean to 'work'. For example, phytoplankton (autotrophs) need light, nutrients, CO2 (dissolved gases) to photosynthesize.

Answer:

Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature. Sunlight is one the most important abiotic factors for marine ecosystems.

Explanation:

Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population.

ORR

Struggle for existence, variation and inheritance. These are said to be the necessary and sufficient conditions for natural selection to occur.
