Chemical energy stored in food molecules is released through respiration.
What is cellular respiration?Cellular respiration is a sequence of chemical reactions which usually break down glucose to produce ATP, which can then be used as energy to power a variety of reactions throughout the body.
The cell, as we know, is the structural and functional unit of life, and each cell requires energy to function.
As a result, cellular respiration refers to respiration that occurs at the smallest level of our bodies, namely the cellular level.
Solar energy is harvested as chemical energy in photosynthesis, which converts water and carbon dioxide to glucose.
As a byproduct, oxygen is produced. Oxygen is used in cellular respiration to break down glucose, releasing chemical energy and heat in the process.
Thus, through respiration the chemical energy is released.

One cell phone contains many metals, including about 25 g
of aluminum, about 15 g of copper, about 0.03 g of gold,
and about 0.3 g of silver.
Based on this information, which resource is most likely used to make cell
phones?
A. A large river and its streams
B. An old-growth forest of tall trees
C. A farm with sheep and cattle
D. An underground deposit of minerals
The correct answer is D. An underground deposit of minerals.
Explanation
Metals are minerals, that is, they are natural substances that are normally in a solid-state. These resources are generally the product of physical-chemical processes that occur in the underground layers of the earth that transform different materials into these minerals. These minerals are obtained through mining, a process in which the earth's crust is broken until it reaches the place where these minerals are housed and in this way takes them to the surface to use them in the manufacture of different objects. Therefore, the correct answer is D. An underground deposit of minerals.

How variation leads to one clover being better suited to their environment than the other?
Answer and Explanation:
Clovers are plants that can contribute to livestock procedures to soil stabilization. Clovers increased forage yield, soil improvement and biological nitrogen fixation, land beautification, an extension of the growing season, and improved forage quality. Clover species have different characteristics. Some species are more tolerant of soil conditions, climate conditions and management regimes than other species. Clovers may also differ concerning the benefits they provide, such as if forage growth is desired at a particular time, one clover might be a good choice than another. It is important to keep in mind the traits of numerous clovers when the planting decisions are made. Other factors such as climate condition, soil condition and grower objectives are also essential factors influencing which clover will be the best plantation choice. Annual clovers complete their life cycle in one year. Annual clovers do not reproduce by vegetative propagation; they only reproduce from seed.

Answer:
1. Rocks in Earth's mantle and crust melt due to extreme temperatures and turn into magma.
2. Hot magma erupts as lava above Earth's surface during a volcanic eruption.
3. Being exposed to a cooler temperature, the lava starts to cool down quickly.
4. The lava solidifies into a rock formation with a fine-grained or smooth surface.
Explanation:
Igneous rocks (also called magmatic rocks) are rocks formed in the process of solidification of magma or lava. Igneous rocks formed above Earth's surface are referred to as extrusive, while those formed below the Earth's surface are referred to as intrusive.
There are several types of extrusive igneous rocks: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff.
When lava cools down too quickly, volcanic glass is created.

Read the section "Brains Under Construction."
Select the paragraph from the article that suggests
specific regions of the brain can perform multiple
functions.
A. Let's break that down, starting with preteen
and teen behaviors. The brain region that tells
us we shouldn't eat chips all the time and
helps us resist that urge is the last to
mature. Called the prefrontal cortex, this
region doesn't fully develop until we are in our
early 20s.
B. "Most of our complex brain functions happen
in the prefrontal cortex, says Reichelt. This
includes complex math and reading, but she
notes that it also includes "how to assess risky
behavior."
C. In fact, these regions are even more sensitive
when we are young. That's because of a
natural chemical called dopamine. Dopamine
is sometimes called the "feel good chemical,
and it lifts our mood when we experience
something rewarding. And it is especially
active in adolescent brains.
D. The teen brain, thus, has two strikes against it
when it comes to resisting junk food. 'It has a
heightened drive for rewards and reduced self-
regulation," says Reichelt.

An individual running a marathon may experience periods of oxygen deprivation that can lead to
A. anaerobic respiration in muscle cells, forming lactic acid
B. acrobic respiration in muscle cells, generating glycogen
C. anaerobic respiration in liver cells, producing glucose
D. aerobic respiration in liver cells, synthesizing alcohol
Answer:
A. anaerobic respiration in muscle cells, forming lactic acid
Explanation:
Running marathon is a vigorous exercise, which often leads to excessive use of oxygen in the cells of the athlete. This causes the cells to switch from the aerobic (with oxygen) to the anaerobic (without oxygen) mode of respiration. This anaerobic respiration produces a product called LACTATE OR LACTIC ACID.
The lactic acid becomes excessive and gets stored in the muscle cells of the athlete. This often leads to cramps, muscle pulls etc. during the marathon. Therefore, an individual running a marathon may experience periods of oxygen deprivation that can lead to anaerobic respiration in muscle cells, forming lactic acid.

Meiosis is a life process associated with sexual reproduction. Which choice correctly summarizes meiosis into one statement?
O Haploid cells join and produce diploid daughter cells.
O Chromosomes in a haploid cell are pulled apart, creating two haploid daughter cells,
O Chromosomes in a diploid cell uncoil and line up, creating two diploid daughter cells.
Homologous chromosomes in a diploid cell separate and produce four haploid daughter cells.
Answer: fourth option: homologous and four haploid daughter cells.
Explanation:
Meiosis is a type of reduction division, in which the diploid parent cell gives rise to haploid daughter cells. Meiosis is a characteristic feature of sexual reproduction.
The correct answer is:
Option D. Homologous chromosomes in a diploid cell separate and produce four haploid daughter cells.
Meiosis is described as:
1. Meiosis gives rise to haploid daughter cells from the diploid parent cell.
2. Meiotic division is observed in the sexually reproducing organism.
3. The mechanism involves the separation of homologous chromosomes in diploid cells to produce four haploid daughter cells.
4. The separation in meiosis occurs through different stages, such as prophase, metaphase, anaphase, and telophase.
Thus, the separation of homologous chromosomes gives rise to four haploid cells in the meiotic division.
Therefore, option D is correct.

The yeast cannot survive above 30 degrees Celsius.
The mecdes that regulate fermentation perform optimally at temperatures below 10 degrees Celsius.
JESTOS
Answer:
The yeast cannot survive above 30 degrees Celsius.
Explanation:
Fermentation is a form of anaerobic respiration carried out by cells of certain organisms like yeast. The process yields products like carbon dioxide (CO2) and alcohol. Hence, the rate of fermentation can be measured by the amount of CO2 or alcohol produced.
According to this graph, which graph shows the rate of alcoholic fermentation for yeast at different temperatures, it can be observed that the rate of fermentation increased at 10°C and began to decrease at 30°C. This data portrays that yeast cannot survive above 30 degrees celsius (°C), hence, the rate of fermentation decreased.
