describe the role of proteins in the release of energy stored in ATP
The role of proteins in the release of energy stored in ATP is that protein is the holder of ATP that is broken down.
What are proteins?Proteins are big, complex molecules that perform numerous important functions in the body. They are essential for the structure, function, and regulation of the body's tissues and organs and do the majority of the work in cells.
Proteins are also used in the synthesis of ATP. Other than proteins, glucose, and fats synthesize energy. Proteins break down the bonds in ATP to release energy. Proteins can either form pyruvate or Acetyl Co-A and participate in aerobic respiration to produce ATP.
Therefore, proteins play a part in the release of energy held in ATP by acting as the keeper of the ATP that is broken down.

Professor Whitney has a sample of lead and a sample of iron. The samples have equal mass. When Whitney heats the samples, the lead reaches a higher temperature than the iron, even though both samples absorbed the same amount of thermal energy. What can Whitney conclude from this experiment?
Iron is a better conductor of heat than lead.
Lead is a better conductor of heat than iron.
Lead has a higher heat capacity than iron.
Iron has a higher heat capacity than lead.
Answer:
The correct answer would be "Iron has a higher heat capacity than lead".
Heat capacity can be defined as the amount of heat transferred required in order to raise the temperature of an object by 1°.
The higher the heat capacity the more the heat transfer is required to raise the temperature.
Iron has higher heat capacity as compared to the lead due to which it requires more heat transfer to raise the temperature of the iron as compared to the lead.
It is why the temperature of the lead increases more as compared to iron even though they absorbed the same amount of thermal energy.
Answer:
The correct answer is "Iron has a higher heat capacity than lead."
Explanation:

Explain why the chromosomes in the second drawing have sister chromatids, but the chromosomes in the third drawing do not. What happened to the sister chromatids?
The chromosomes in the second drawing have sister chromatids because DNA has replicated during the S phase of interphase, resulting in two identical copies that are joined at the centromere. By the third drawing, the sister chromatids have likely separated during anaphase, making them individual chromosomes.
Explanation:The chromosomes in the second drawing have sister chromatids because during the S phase of interphase, DNA replication occurs, which results in each chromosome being composed of two identical copies. These copies, called sister chromatids, are joined together at a region known as the centromere and are visible under a light microscope in the familiar "X" shape. The absence of sister chromatids in the third drawing is likely due to the chromosomes having moved into a stage of cell division known as anaphase, during which the sister chromatids are pulled apart toward opposite poles of the cell, thus no longer existing as attached pairs but as individual chromosomes.
Because second drawing twins (chromatids) separate in phase three, becoming solo chromosomes.
Here's why the chromosomes in the second drawing have sister chromatids, but those in the third drawing don't:
Second Drawing:
* The chromosomes in the second drawing have sister chromatids because they are in the prophase stage of cell division. In prophase, DNA replication has already occurred, resulting in each chromosome being duplicated. These two identical copies stay attached at the centromere and are called sister chromatids.
Third Drawing:
* The chromosomes in the third drawing lack sister chromatids because they are in the anaphase stage of cell division. During anaphase, the spindle fibers pull the sister chromatids apart towards opposite poles of the cell. This means each chromatid becomes an independent chromosome.
Therefore, the sister chromatids in the second drawing have simply separated and moved to opposite poles in the third drawing. This separation is a crucial step in cell division, ensuring that each daughter cell receives a complete set of chromosomes.
mitosis is done by your body cells this cartoon illustrates and exception what types of cells do not undergo mitosis
Most cells in the human body reproduce using mitosis, however, sex cells (or gametes) like sperm and egg cells do not. They are produced through a different cell division process called meiosis, which results in cells with half the number of chromosomes, facilitating genetic variation in offspring.
Explanation:In the human body, most cells reproduce using a division process known as mitosis. However, there is one type of cell that does not undergo mitosis: sex cells or gametes. These cells, specifically sperm and egg cells, are formed through a different cell division process called meiosis.
In meiosis, the resulting cells have half the number of chromosomes than the original cell allowing genetic variation in offspring. While in mitosis, the resulting cells are genetically identical to the original cell, maintaining the same number of chromosomes. This is why mitosis is used for growth and repair in the body, and meiosis is used for sexual reproduction.

When we consider personal water use, people in developed countries use more water compared to those in developing countries.
How is water usage in developed countries different from developing countries?In a developed country like America, the average water use by a family is about 552 gallons comparing it to an African family which uses about 5 gallons of water every day. In developing countries, women have to walk about 4 miles to fetch water. An average person needs 20 to 50 liters of water each day for cooking, cleaning, drinking, and sanitation.
Water is one of the most important resources for human health, environmental protection, poverty alleviation, sustainable development, peace and security. Yet, more than 40% of people worldwide lack access to clean water.
Water scarcity affects several sectors, such as food security. About 70% of global freshwater is used by agriculture. Water scarcity, flooding, and water quality are the primary causes of water-related diseases in developing countries. In the developing world, water-related illnesses account for up to 80%.

Which best describes the life cycles of moss and angiosperm?
I. Both life cycles have protected seeds.
II. Both life cycles involve meiosis.
III. Moss fertilization occurs in the air; angiosperm fertilization occurs in a pool of water.
IV. Moss release haploid spores into the surrounding environment; angiosperm release haploid pollen grains into the surrounding environment.
Ans. Option (IV).
Mosses can be defined as non-vascular, flowerless plants that are found in shady or damp regions and reproduce via haploid spores. During reproduction in moss, haploid male gametes or spores are released into surrounding environment that fuse with female spores to form zygote that develop into mature sporophyte.
Angiosperms are vascular, flowering plants that reproduce by seeds. During reproduction in angiosperms, haploid male gametes or pollen grains are released into surrounding environment that fuse with female gametes or eggs to form zygote that develop into seed.
Thus, the correct answer is option (IV).

2. Helps know the fertile period
3. To be more productive
4. Improve the life of husband and wife
Explanation:
1. To maintain health and fitness
In the second week after menstruation is finished, increasing estrogen in the body will provide lots of energy when exercising. The body will be able to burn more bad fats and calories.
2. Helps know the fertile period
In planning a pregnancy, this will be very helpful. Most women will reach the peak of fertility between 12 to 16 days before menstruation. It also can be seen that the most infertile period is the days after the menstrual period is finished or ended.
3. To be more productive
What is meant here is that women will be more productive at work. According to Dr. Harper, women tend to feel more productive during the 2-week monthly period.
4. Improve the life of husband and wife

state the numbered position of the moon that could result in a lunar eclipse
Final answer:
A lunar eclipse occurs when the Moon enters the Earth's shadow during its full phase when the Sun, Earth, and Moon are aligned.
Explanation:
A lunar eclipse occurs when the Moon enters the shadow of Earth. This event can only happen when the Sun, Earth, and Moon are precisely aligned, meaning the Moon has to be in its full phase. During a lunar eclipse, if you imagine the Earth's dark shadow as a numbered area, the Moon must be in the number corresponding to the darkest part of the Earth's shadow. This is a necessary condition for a lunar eclipse to occur and for the phenomenon to be observable from Earth.
An eclipse of the Moon, also known as a lunar eclipse, can occur when the Sun, Earth, and Moon are in a line. The Moon enters the shadow of the Earth, causing it to darken. The numbered position of the Moon that could result in a lunar eclipse is position 1, where a total eclipse occurs.
