What is the difference between cellular respiration and getting energy from a log by burning it?

Answers

The stored chemical energy is eventually released during cellular respiration through a sequence of enzyme-aided processes. When a log burns, chemical energy that has been stored is swiftly released as heat and light.

     

Living cells need respiration, a biological process, to release energy. A chemical reaction called combustion takes place outside of living organisms or cells. A controlled biological process, respiration. It is impossible to control combustion. When there is oxygen present, substances undergo a chemical reaction known as burning, which produces significant amounts of heat and light. Similarities between burning and respiration For the creation of energy, both processes need oxygen. As a byproduct, they emit carbon dioxide. The metabolic process known as respiration is when an organism obtains energy from the breakdown of glucose molecules in the form of ATP molecules.

When compounds are exposed to oxygen, a chemical reaction known as burning takes place.

Label the following blood pressure readings as hypotensive, normal, pre-hypertensive, or hypertensive.

Answers

The following blood pressure readings are :

100/70 - Normal

150/95 - Hypertensive

130/85 - Pre-hypertensive

80/50 - Hypotensive

High blood pressure is nothing but high blood pressure and is a serious condition because it forces the heart to work harder to pump blood throughout the body and can increase the risk of heart attack, stroke and kidney failure if left untreated. Likewise, low blood pressure is hypotension.

Normal blood pressure varies from person to person, but the American Heart Association recommends a target blood pressure of less than 120 mm Hg systolic and less than 80 mm Hg diastolic. Stage 1 hypertension is when a person has a systolic blood pressure of 130-139 or a diastolic blood pressure of 80-89.

Identify the type of symbiosis described. the saguaro cactus provides food for the white-winged dove through its large fruit. the bird consumes the fruit, ingests the seeds, and then deposits the seeds in a new location.

Answers

This is an example of mutualism, a type of symbiosis in which both species benefit. In this case, the saguaro cactus provides food for the white-winged dove, and in return the dove deposits the seeds of the cactus in new locations, helping the cactus to propagate.

Mutualism plays an important role in nature, as it helps to ensure the survival of both species. In this case, the saguaro cactus needs the white-winged dove to spread its seeds and help it to propagate, while the dove relies on the cactus for food. This type of symbiotic relationship can be seen in numerous species throughout the world, and is an important factor in maintaining the balance of nature.

In addition to providing food for the white-winged dove, the saguaro cactus also offers other benefits. Its large fruit is a valuable source of nutrition for other species, such as birds, mammals, and reptiles. The cactus also provides shelter for various animals, including bats, lizards, and hummingbirds. The shade from the cactus helps to keep the environment cooler, which can be beneficial to other species in the area.

What are 3 things that support the theory of evolution?

Answers

Fossil evidence, biogeographical evidence, and anatomical evidence were some of the many types of evidence that Darwin utilised to support his theory of evolution by natural selection.

We'll examine a variety of sources of information to examine the evidence for evolution, including both anatomy and embryology. An evolutionary heritage can be determined by similar anatomical traits between organisms, including those that are only observable during embryonic development.

Molecule biology We can tell how closely related two creatures are by comparing and contrasting the "same" gene in those animals (i.e., a pair of homologous genes).

Biogeography - We can retrace the evolutionary history of species by looking at their geographic distribution.

Fossils - However, it confirms the existence of now-extinct species and occasionally captures potential "in-between" species. The fossil record is not a complete record of evolutionary history, forms on the path if present day species.

What is the difference between getting energy from cellular respiration and getting energy from a log by burning it?

Answers

During cellular respiration, stored chemical energy is gradually released in a series of enzyme-assisted reactions. Burning a log releases the stored chemical energy rapidly as heat and light.

The energy produced by cellular respiration is in the form of chemical bond energy. The energy produced when a log of wood is burned is mainly heat or heat energy and some light energy.

The third phosphate bond of adenosine triphosphate (ATP) is a high-energy bond. It is used to provide energy for metabolic reactions and perform tasks such as muscle contraction. Energy is the ability to execute work. It is electricity obtained from a physical or chemical source and used to provide heat or light or to do work. Forms of energy include chemical, thermal, mechanical, electrical and nuclear energy. Energy can be transformed from one mode to another.
