Answer 1
It’s the initials for the word
Answer 2

Answer:

So basically the rows are called periods, and the columns are called groups. The groups show that those elements have similar characteristics. There are also different families such as the noble gases and alkali earth metals. The elements are placed where they are because of the atomic number which is directly equal to the number of protons there are. The atomic mass is the number of both protons and neutrons. Also, even though the number of protons can be equal to the number of electrons, that isn't always the case. It could be an isotope which is basically for when an element or atom isn't neutral. Umm, so, I hope this helped. I know it's very long but if you need anything else just ask!! c:

Organisms that live in the tundra have developed unique adaptations that aid in their survival. Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. It is the largest terrestrial carnivore, but it is also an excellent swimmer that spends much of its time in and near the water hunting its favorite food. It has large paws with small bumps to provide traction as it walks across the ice. Its fur is helpful as camouflage during the winter months, but not as helpful during the summer. Which organism has the adaptations described that enable it to survive in the tundra

Answers

Answer: The organism that has the adaptations described that enable it to survive in the tundra is the POLAR BEAR.

Explanation:

ADAPTATION is defined as the process by which an organism becomes fitted to its environment thereby enabling the organism to live successfully and reproduce.

In any population, an organism is able to survive if it has features that help them to fit and compete successfully in that environment.

From the question, a typical example was given concerning the POLAR BEAR (Ursus maritimus) and it's best fitted environment which is the tundra.

The tundra is a type of biome that is treeless marshy vegetation which is composed mainly of dwarf shrubs. It's has a cold climate (Arctic region) with long icy winters and very short summer with an average temperature of 10°C.

Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. These adaptations include:

--> The presence of a thick coat of insulated WHITE FUR: this helps it to survive the cold environment by acting as an effective insulator. The fur is also found at the base of its large paws with small bumps, which protects it against cold surfaces and provides its with a better grip of ice as it walks across it. It also gives it a concealing coloration making it unnoticed while it stalks its prey in the snow. These are the features that enables it survive the terrestrial environment if tundra.

--> it also has some aquatic adaptations which enables it to hunt it's favourite food which is seals. The presence of large front paws which are slightly webbed allows them swim for a long distance in search of food.

C) Competition for food resources with another native species.

D) The introduction of a new predatory species to an island by boat.

Answers

The answer is A
_____________

The statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.

What is species?

Species may be characterized as a group or collection of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. The process of speciation is generally mediated through the species.

In the present time, the human causes of the extinction of species are majorly popular. It includes the clearance of an area for farmland and industrialization, the building of a dam for city water utilization, the introduction of a new predatory species to an island by boat, and many more.

But the process of competition for food resources with another native species is ultimately the behavior governed by the respective species itself without the interference of humans.

Therefore, the statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.

In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. increase : active hyperemic response decrease : dilation of the arterioles decrease : increase in tissue ischemia decrease : active hyperemic response increase : constriction of the arterioles

Answers

Answer:

The correct answer is - increase: constriction of the arterioles.

Explanation:

When the physical activity is decreased by the tissues of the muscle, the oxygen concentration in the tissue increases which leads to the constriction of the arterioles.

It takes place in order to decrease blood flow and blood pressure as oxygen requirement is less in the tissue in decreased physical metabolic activity. The constriction of arterioles results in more resistance to decrease the blood flow in capillaries.

Explanation:

The level of carbon dioxide in the blood is monitored by nerve tissue. If you exercise strenuously, the increase in cellular respiration consumes oxygen from the blood and produces surplus carbon dioxide removed in the blood. Since this physical exertion requires faster breathing to replenish oxygen supplies and carry away carbon dioxide, the carbon dioxide sensors result in signals from the brain to increase breathing rate. After you have rested, and carbon dioxide levels are back to normal, your breathing rate decreases too. This is an example of

Answers

Answer:

Negative feedback.

Explanation:

The normal carbon dioxide levels after resting, the breathing rate also decreases which is an example of negative feedback because the body moves towards stability or equilibrium conditions. There is a direct relationship between breathing rate and carbondioxide levels means if one is increases the other automatically increases in order to maintain homeostasis in the body so we can say that this relationship is very important to maintain .stability in the body

Energy is required for a variety of vital biological and cellular functions, including ATP hydrolysis. These include active transport, Purinergic signaling, synaptic signaling, intracellular signaling, DNA and RNA synthesis, and muscular contraction.

What do you understand by cell ?

The fundamental units of all living things are cells. There are many billions of cells in a human body. They provide the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks.

Adenosine triphosphate molecules directly provide the energy needed for cellular functions (ATP). One adenosine molecule and three phosphate groups, or Pi for short, make up ATP. The chemical energy that is stored in each ATP molecule is not very large. By dissolving ATP into adenosine diphosphate (ADP) and a phosphate group, this energy may be released.

Compare the concentration of connective tissue cells found in bone with the concentration of those found in blood.

Answers

Answer: CONNECTIVE TISSUE is the most abundant tissue in the body which are widely separated from each other and intercellular substance (matrix) is present in considerably larger amounts. The principal cell of connective tissue are fibroblasts which makes fibres found in almost all connectiv tissues. Some are solid and strong (bone), while others are fluid and flexible( blood).

Explanation:

Connective tissues usually contain fibres present in the matrix which may be of semisolid jelly-like consistency or dense and rigid, depending upon the position and function of the tissue. There are three main types of connective tissue which include:

--> Loose connective tissue

--> Dense connective tissue and

--> specialised connective tissue.

The bone and the blood are considered to be an example of specialised connective tissue. This is so because they both contain a number of different tissues with specialized cells and unique ground substances.

The BONE consists of osteoblasts, osteocytes, and osteoclasts. It is considered to be a specialised connective tissue because the bone cells are surrounded by a matrix of collagen fibres strengthened by inorganic salts, especially calcium and phosphate.

The BLOOD consists of red blood cells, white blood cells, platelets. It is considered to be a specialised connective tissue because the blood cells are surrounded by fluid matrix known as plasma and connecta with other cells through its transport functions.

In COMPARING the concentration of connective tissue cells or bone and blood, the connective tissue cells of bone comsist of fibre and collagen which makes it dense and rigid while the connective tissue cells of blood does not contain any fibre, therefore it's flexible.
