Answer:
As muscle activity increases, the muscles require more energy to continue contracting. This energy is provided by the breakdown of glucose and other organic molecules, which generates ATP (adenosine triphosphate) - the energy currency of cells. This process of energy production releases carbon dioxide as a byproduct, which must be eliminated from the body. The muscles also require an increased supply of oxygen to support the energy production. The increased muscle activity leads to an increase in blood flow to the muscles, bringing more oxygen and removing more carbon dioxide. Therefore, to maintain efficient muscle activity, the body must coordinate the delivery of oxygen and removal of carbon dioxide to and from the muscles.

For this assignment, you will conduct research to find the actual sizes of the Sun and the planets. Then, you will use an online solar system model calculator to determine the scaled sizes of these celestial bodies. Finally, you will use this information to create a scale model of the solar system.
Background Information
Models are representations of ideas, objects, phenomena, and even systems. A drawing of a tree is an example of a model because it represents a real tree. The tree cannot be drawn on paper in its actual size because it would not fit. When real objects are too big or too small, scales are used so objects can be properly modeled. A scale is the ratio of the size of a model to the size of the real object. For example, you want to draw a tree that is 1,500 mm tall. You could draw a tree that is 150 mm tall on paper. The drawing on the paper is ten times smaller than the real tree and is called a scale model.
Scale models can be smaller, as you have seen, or bigger than the objects or systems they represent. A scale model of the solar system that shows the relative sizes of the planets is smaller than the actual solar system. Scale models are helpful for comparing the parts of a system. They are also used to show the relationships between or among the parts of a system.
Planets in the solar system
SunThe solar system consists of various celestial bodies in it, such as planets, asteroids, satellites, and others. The solar system itself has eight planets in it. The planets in the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. In fact, it was rumored that Pluto was one of the planets in the solar system, but this was not confirmed.

How are alleles on homologous chromosomes distributed during meiosis? I understand the # of chromosomes is 2n at the end of meiosis 1 and n after meiosis 2, but I'm having a hard time visualizing how specific alleles go where during the different stages.
The specific question is: "An organism has alleles R1 and R2 on one pair of homologous chromosomes and T1/T2 on another pair. Diagram these homologs at the end of metaphase I, at the end of telophase I, and at the end of telophase II, and show how meiosis in this organism produces gametes expected in Mendelian crosses. Assume no crossover." This is from a textbook and the solution provided is here but I wasn't sure if it was correct or not due to the 2 thumbs down (it also didn't address the second part of the question regarding Mendelian crosses):
Answer:
During meiosis, the homologous chromosomes separate and become sorted into different daughter cells. At the end of metaphase I, the homologous chromosomes are lined up in the center of the cell, attached at the centromere, and pulled towards opposite poles by the spindle fibers. During telophase I, the chromosomes reach opposite poles and the cell begins to divide. In telophase II, a second cell division occurs, resulting in the formation of four genetically diverse daughter cells, each with half the original number of chromosomes. In the case of the organism with alleles R1 and R2 on one pair of homologous chromosomes and T1/T2 on another pair, the distribution of alleles is random during meiosis. At the end of telophase II, the four daughter cells will have a mix of R1, R2, T1, and T2 alleles, making them genetically diverse from one another and from the parent cell. These diverse gametes can produce a variety of offspring when involved in Mendelian crosses.

If the ozone layer were completely removed, what effect would that change have on temperature?
The temperature would remain unchanged.
The temperature of Earth would increase.
The temperature of the upper atmospheric layers would decrease.
The temperature of Earth would decrease.
The temperature of the stratosphere would decrease.
Answer:
Ozone layer is the topmost layer of the atmosphere of Earth.
If the ozone layer were completely removed, the temperature of Earth would increase.
Explanation:
The sun's ultraviolet (UV) radiations are a leading cause of premature aging, skin cancer, and even death.
As a key part of Earth's atmosphere, the ozone layer plays a crucial role in protecting the planet from harmful ultraviolet (UV) rays. Most of the sun's UV rays are absorbed by the ozone layer, and the energy is then released as heat in the upper atmosphere.
Since the discovery of the ozone hole over Antarctica, global warming has been identified as the primary factor in the planet's warming. If the ozone hole continues to grow, it will have devastating impacts on Earth's atmosphere and make life here almost impossible.
Because of this, if the ozone layer were ever to be destroyed entirely, global warming would occur.

how did nepa revolutionize environmental protection in the united states
Answer: The National Environmental Policy Act (NEPA) was signed into law by President Nixon in 1970 and it revolutionized environmental protection in the United States by establishing a comprehensive national policy for the protection of the environment.
NEPA requires federal agencies to consider the environmental impacts of their actions and to provide an assessment of those impacts to the public. This process is known as an Environmental Impact Statement (EIS). The EIS requires agencies to analyze the environmental effects of proposed actions, alternatives to those actions, and the impacts of no action.
This act also established the Council on Environmental Quality (CEQ) to oversee the implementation of NEPA and to provide guidance to federal agencies on how to conduct the EIS process.
NEPA has played a critical role in protecting the environment by requiring federal agencies to consider the environmental impacts of their actions and to involve the public in decision-making. It has also helped to prevent or mitigate the negative impacts of federal actions on the environment.
The law also provided a framework for a robust public participation process in which citizens, organizations and tribes can raise concerns and provide input on proposed federal actions that may impact their environment.
In summary, NEPA revolutionized environmental protection in the United States by establishing a comprehensive national policy for the protection of the environment, requiring federal agencies to consider the environmental impacts of their actions, involving the public in decision-making and provided a framework for a robust public participation process.

A primary succession is when lichens start to grow on exposed bare rock after a glacier retreats and a deciduous forest is clear-cut.
Primary succession is a type of ecological succession (the development of an ecological structure within a biological community) in which plants and animals first occupy a lifeless, sterile environment. Pioneer species are those that are the first to establish themselves in a brand-new environment. Through their interactions, these species create a basic initial biological community. As new species enter this society, it becomes more complicated.
Following a severe disturbance, primary succession is the first stage of ecological recovery and typically takes place in an environment devoid of vegetation and other living things. As a result of environmental disturbances like lava flows and retreating glaciers, these habitats often lack soil.

To explain the increase in mass of the light-grown plants, identify one inorganic source of new plant mass and connect it to the cellular process underlying the increase in mass.
The inorganic source of new plant cell mass is Carbon dioxide (CO₂).
Carbon dioxide is taken up by plants from the atmosphere only with the help of a process known as Photosynthesis. Photosynthesis is the process by which plants make their food (glucose) using carbon dioxide and water and sunlight. The glucose or sugar produced will be converted into starch, cellulose, and other chemical compounds.

a.AGGTACGTACTCATG
b.UCCAUGCAUGAGUAC
c.GTACTCATGCATAGG
d.AGATCACTACGCGTC
Answer:
The correct mRNA strand is b. UCCAUGCAUGAGUAC.
This is because in transcription, the DNA strand is used as a template to create a complementary RNA strand. The process is called transcription, and the enzyme that carries out this process is called RNA polymerase. During transcription, the enzyme reads the DNA sequence in the 3' to 5' direction, and it synthesizes a complementary RNA strand in the 5' to 3' direction. In the process of transcription, Adenine (A) in the DNA strand pairs with Uracil (U) in the RNA strand, Cytosine (C) in the DNA strand pairs with Guanine (G) in the RNA strand, and vice versa. So the strand AGGTACGTACTCATG, when transcribed, will result in the complementary strand UCCAUGCAUGAGUAC.
