How do all of the parts of this organism work together in order for it to function properly? Explain your answer.
Answer:
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.
Explanation:
brainliest?
The basic components of the complex human organism is made up of cells. Its level of organization are coordinated with each other to perform specific function.
what are the level of organization ?The primary chemical level of organization include atoms, ions, and small molecules which are joined to form macromolecules; The macromolecule include larger molecule like amino acid, carbohydrate, fats, nucleic acid where the basic components are carbon, hydrogen and oxygen atoms.
This macromolecule act as biomolecule at cellular level, the cellular level include the smallest unit of living organism, it can be unicellular and multicellular in nature based on complexity of the organism.
The tissue level of organization include a number of cells are gathered together and perform a specific function called tissue like epithelial, connective, muscular tissue.
The organ level include groups of tissues which work together to perform a higher-level function like stomach, heart etc; The organ system include all of the organs involved in doing a vital function, like digestive system, circulatory system,
In this way a complex organism perform their activities.

Is energy stored when ATP is hydrolyzed?
Answer: ATP hydrolysis is the catabolic reaction process by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released by splitting these bonds, for example in muscles, by producing work in the form of mechanical energy.
Explanation: Mark me as (brainlisti) pls
Answer:
ATP is an excellent energy storage molecule to use as "currency" due to the phosphate groups that link through phosphodiester bonds. These bonds are high energy because of the associated electronegative charges exerting a repelling force between the phosphate groups. A significant quantity of energy remains stored within the phosphate-phosphate bonds. Through metabolic processes, ATP becomes hydrolyzed into ADP, or further to AMP, and free inorganic phosphate groups. The process of ATP hydrolysis to ADP is energetically favorable, yielding Gibbs-free energy of -7.3 cal/mol.[1] ATP must continuously undergo replenishment to fuel the ever-working cell. The routine intracellular concentration of ATP is 1 to 10 uM.[2] Many feedback mechanisms are in place to ensure the maintenance of a consistent ATP level in the cell. The enhancement or inhibition of ATP synthase is a common regulatory mechanism. For example, ATP inhibits phosphofructokinase-1 (PFK1) and pyruvate kinase, two key enzymes in glycolysis, effectively acting as a negative feedback loop to inhibit glucose breakdown when there is sufficient cellular ATP.
Conversely, ADP and AMP can activate PFK1 and pyruvate kinase, serving to promote ATP synthesis in times of high-energy demand. Other systems regulate ATP, such as in the regulatory mechanisms involved in regulating ATP synthesis in the heart. Novel experiments have demonstrated that ten-second bursts called mitochondrial flashes can disrupt ATP production in the heart. During these mitochondrial flashes, the mitochondria release reactive oxygen species and effectively pause ATP synthesis. ATP production inhibition occurs during mitochondrial flashes. During low demand for energy, when heart muscle cells received sufficient building blocks needed to produce ATP, mitochondrial flashes were observed more frequently. Alternatively, when energy demand is high during rapid heart contraction, mitochondrial flashes occurred less often. These results suggested that during times when substantial amounts of ATP are needed, mitochondrial flashes occur less frequently to allow for continued ATP production. Conversely, during times of low energy output, mitochondrial flashes occurred more regularly and inhibited ATP production.[3]

The concept of emergent property definition
Answer:
definition
Explanation:
An emergent property is a property which a collection or complex system has, but which the individual members do not have. In biology, for example, heart is made of heart cells, heart cells on their own don't have the property of pumping blood.
Based on your observations would you SUPPORT OR REFUTE The following statement “Eclipses occur at the same place on Earth every time”. Please make sure to backup your answer with an observation or fact.
Two positively charged objects (Object A and Object B) are 8 inches apart. When a positively charged ball is hung at an equal distance between the two positively charged objects, the ball moves toward object B (see figure).
What can you conclude about the relative amount of positive charge on Object A and Object B? Provide support for your claim.
Your answer:
Answer:
Object B has more charge than Object A
Explanation:
Generally, unlike charges attract each other and like charges repel each other but it happens in a very rare case when like charges attract each other. It is so due to charge difference between the objects.
In the given example a positively charged ball moves towards positively charged object B because object B has more charge than object A and the ball. Due to large difference in the charges between two positive charges, positive charges are displaced at opposite end and object B get concentrated with negative charges that allows ball to move towards Object B.
Hence, the correct answer is "Object B has more charge than Object A".

Which of the following statements correctly compares terrestrial and Jovian planets?
А
Jovian planets are generally warmer due to their proximity
to the Sun.
B
Terrestrial planets have longer
periods of revolution.
С
Terrestrial planets are denser due to their rocky composition.
D
Jovian planets are smaller in diameter.
Answer: C
Explanation: terrestrial planets are denser then the Jovian (Outer) planets since they are mostly made of rocky material, while the Jovian planets are gaseous.
Saturn, for example, would theoretically be able to float in water due to its low average density.

Describe and explain the purpose of phototropism and gravitropism in plants and explain why this feature is important for the survival of plants (6 marks)
QER question so marks for spelling etc too but if anyone has bullet points of things to include that would be great! :)
Answer:
Plants have a variety of developmental, physiological, and growth responses to light—sometimes only to particular wavelengths of light.
In phototropism a plant bends or grows directionally in response to light. Shoots usually move towards the light; roots usually move away from it.
In photoperiodism flowering and other developmental processes are regulated in response to the photoperiod, or day length.

farming practices that expose topsoil to water and wind often result in which degraded the soil and can ultimately threaten food production
Answer:
Soil erosion and lost of fertility.
Explanation:
The farming practices that expose topsoil to water and wind often result in erosion of the soil because the wind and water takes particles with them. If water and wind removes the soil particles continuously then the land become barren and lost its fertility which leads to lower production of food crops that ultimately threaten the food production for the population.
why is everyone stressing this week?

cause i just had to take a math test plus I have an essay to write and I have know idea how but i sent in a rough draft but he said it needs to be 3 pages longer but I don't really know how to write an essay like that but the rough draft i had help on sooo yea
Explanation:
When people think about the first people in America, they might think of Christopher Columbus or the European colonists; when, in fact, the first people were the Indians. The Cherokee Indians had lived in the lands of what is now the United States for thousands of years before any colonists had ventured over. Little did they know that the new nation that was going to be forming around them, would severely affect the lives of their descendents.
Life before the Trail of Tears but after the arrival of the new Americans was more or less simple for the Cherokees. They spend time hunting and fishing. Some of them even worked on plantations and even owned their own slaves, in an effort to accommodate some of the American ways of living.
this is the rough draft but it needs more if you know anyone who can help it's much appreciated :)

How do you think the rock layers and fossils found in Red Rock Canyon can provide evidence for Earth's geologic history?
Answer and Explanation:
Red Rock Canyon is an area of universal geologic interest, located a few miles west of Las Vegas within the Mojave Desert. Many experienced geologists visit the Red Rock; they are surprised by the vivid colors of rocks, natural beauty, and rock formations. A visual display takes million years to make the masterpiece known as the Red Rock Canyon National Conservation area. About 500 million years ago, Red Rock Canyon was found at the bottom of an ocean basin. Limestone accumulated in this ocean basin, which contains the fossils of sea life. The tracks of two-footed meat-eating dinosaurs have been found in the Aztec Sandstone. The tracks of small animals such as spiders, scorpions, early mammals, and proto-mammals were also found. The fossils and rock layers that are found in Red Rock Canyon provide evidence for Earth’s geologic history. Paleontologists are still searching these areas.
A DNA sample contains 30% cytosine. What percentage of the sample would be thymine?
Answer:
30% Thymine
Explanation:
If 30% of Adenine is present, it would be reasonable to assume that 30% of Thymine will be present, as the ratio between the two complementary nitrogenous bases will be roughly equal.
Therefore, that leaves us with 40% between Cytosine and Guanine. Since the ratio between them would be equal, it gives us 20% of Cytosine and 20% of Guanine.
Therefore:
30% of A + 30% of T + 20% of C + 20% of G = 100% DNA
20% of thymine is present in a DNA sample that contains 30% cytosine.
What is DNA?DNA stands for deoxyribonucleic acid.It is a polynucleotide chain.A nucleotide consists- a nitrogenous base, deoxyribose sugar and phosphate group.Nitrogenous base are of two types- Purines(Adenine and Guanine) and Pyrimidine(Cytosine and Thymine).Adenine pairs with Thymine and Guanine pairs with Cytosine.What is thymine?Thymine is a Pyrimidine nitrogenous base which forms double bond with Adenine.What is cytosine?Cytosine is a Pyrimidine nitrogenous base which forms a triple bond with Guanine.There is 100% nitrogenous base in DNA.
30% of Cytosine means 30% of Guanine=60%(30+30)
So 100-60=40%(Adenine +Thymine)
So, Thymine and Adenine each will have=20%
Hence, the answer is 20% Thymine.

How do the geographic barriers affect the relatedness of species?
Answer:
Scientists think that geographic isolation is a common way for the process of speciation to begin: rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations. This may or may not be sufficient to cause speciation.
