Which of the following indicates that an endothermic reaction has occurred?
O Heat is released
O water is formed
O Salt is produced
O Temperature decreases

Answers

Heat is released because endothermic is the absorption of heat

The  following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.

What is the significance of the endothermic reaction?

There are two types of reactions, such as the reaction that requires heat to form the product, the endothermic reaction, while some of the reactions that release heat are called the exothermic reaction, and the exothermic reactions have more energy at the reactant side than the product side. In the case of a endothermic reaction, the product usually has more energy than the reactants, and the change in free energy here is positive.

Hence, the following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.

Most of the water vapor in the atmosphere comes from evaporation of water from oceans. Most of this evaporation occurs where there is the greatest solar radiation, which is - Group of answer choices around islands in the Pacific. along the coast of Europe. near the Equator.

Answers

Answer:

near the Equator

Explanation:

The part of the Earth that receives the most amount of solar radiation is always near the Equator. This is because the Earth itself revolves around the run in a tilted motion, since the Earth is round this makes the Equator always closest to the sun which means it will always get the most direct amount of Sun Radiation. This radiation causes more heat which ultimately causes a greater amount of water to be evaporated in this location.

The broken bone begins to take the shape it had prior to the fracture.

A mass of tissue containing cells that produce collagen fibers forms. These collagen fibers extend across the broken bone and attach the pieces back together.

A hematoma forms at the fractured area.

Osteoblasts and osteoclasts arrive at the fracture and begin to produce bone tissue there.

Answers

Answer:

The correct order is:

1. A hematoma forms at the fractured area.2. A mass of tissue containing cells that produce collagen fibers forms. These collagen fibers extend across the broken bone and attach the pieces back together.3. Osteoblasts and osteoclasts arrive at the fracture and begin to produce bone tissue there.4. The broken bone begins to take the shape it had prior to the fracture.

Explanation:

After the fracture of a bone several events occur that involve the regeneration and remodeling of the broken bone:

Hematoma in the fracture area is produced by the bleeding of the bone marrow, especially when it occurs in long bones. The collagen fibers are intended to initiate the repair process, trying to join the bone fragments that have separated. The purpose of this is to build a soft tissue base on which the new bone will grow. Osteoblasts and osteoclasts are responsible for the process of ossification and remodeling, respectively. Only a bone scar will remain at the fracture site. With the process of ossification and remodeling, the bone acquires the same shape it had before the injury.

This whole process is necessary for the morphological and functional recovery of a bone when it has suffered a fracture.

Answer: 4, 2, 1 , 3   is the order on Edge.

true or false? diffusion is a result of the random movement of particals

Answers

The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. it is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher concentration to one of lower concentration. However, diffusion can still occur in the absence of a concentration gradient. Diffusion requires energy input from the cell. ... Only water can diffuse across a cell membrane. Molecules move from areas of high concentration to areas of low concentration. - Passive transport is the diffusion of substances across a membrane. - Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a cell's membrane via specific proteins.

Explanation:

Which statement best accounts for the decline in bighorn sheep populations? 1. Predators of the sheep decreased in number. 2. Sheep ewes that have shorter, spiked horns increased in number. 3. Human activities directly and indirectly affected the sheep. 4. The sheep were listed as a "species of concern" by Glacier National Park.

Answers

Answer:

The statement which best accounts for the decline of the bighorn sheep population is - " Human activities directly and indirectly affected the sheep."

Explanation: Explaination of the following statements -

Predators of the sheep decreased in number.

Predation is rarely considered a major mortality factor (Wishart 1975, 1978). It is well known that bighorn sheep are preyed upon, but there is little information available on the effect(s) of predation on the populations of bighorn sheep. Numerous citations document the stalking and/or killing of bighorn sheep by a number of predators.

Thus , this statement is not correct.

Sheep ewes that have shorter, spiked horns increased in number -The larger, wild relative of the domesticated sheep is the bighorn sheep. Males are called "rams" and have long spiral horns, while females are called "ewes" with shorter, spike-like horns. With white areas on the muzzle, the back of the legs and around the rump, the coat is short, coarse and usually brown. The sheep will shed its hair once a year to reveal a new coat underneath.

Thus , the statement does not match with the decline of the bighorn sheep.

Human activities directly and indirectly affected the sheep. -: Disease transmission, human interference, overgrazing, and loss of habitat are often cited as factors responsible for decreases in the abundance and distribution of bighorn sheep. these all factors comes under the human activities which directly /indirectly results in the declination of the bighorn sheep.

Hence, this statement is correct .

The sheep were listed as a "species of concern" by Glacier National Park.  

Home to 400 to 600 bighorn sheep, Glacier National Park lists the animal as a "species of concern," that is, at risk of being endangered.  The research has also shown just how sheep-like bighorns could be. They're creatures of habit, that is.  Therefore , the national park indicated the species at risk , but were not responsible for their declination.

Hence, this statement is incorrect.

Therefore , the correct answer is 3 ( Human activities directly and indirectly affected the sheep.)
