When energy is transferred to or from a substance, it can change the molecules’ freedom of movement. True or False?
Answer:
True
Explanation:
When transfer energy, the substance's temperature changes which can change the molecules' freedom. For example, when water freezes the water molecules loose temperature and slow down, unlike in a gas where molecules are free and energetic.

How does the photolysis of water benefit the biosphere?
1. What do you know about gravity?
2. How could gravity affect the water cycle?
Explain your answer.''
Explanation:
What do you know about gravity?
ans:Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. ... where G is called the Gravitational Constant.
How could gravity affect the water cycle?
ans:It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. ... Gravity pulls denser air and water downward, forcing less dense air and water to move upward. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

Homeostasis is the ability of the body to maintain internal balance despite changing external conditions. How does the respiratory system help maintain homeostasis? The respiratory system helps release hormones to control body processes. The respiratory system helps release unwanted heat and water from the body, The respiratory system produces white blood cells that kill disease causing organisms. The respiratory system releases enzymes that help in the break down of food.
Answer:
b on edge
Explanation:
its right
The respiratory system helps release unwanted heat and water from the body, maintaining homeostasis.
What is homeostasis?" A state of balance among all the body systems needed for the body to survive and function correctly."How respiratory system maintain homeostasis?Respiratory system helps to remove carbon dioxide and excess heat from our body and maintains our blood pH.During respiration, carbon dioxide reacts with water to form a carbonic acid in presence of enzyme carbonic anhydrase. It further dissociates into bicarbonate and H+ ions. This reaction are in equilibriumWhen the level of H+ ions increases, the pH level increases. This will signal respiratory system to release more carbon dioxide. This will result in formation of carbon dioxide and decrease level of H+ ions which will result in increase blood pH.When we breathe out, the moisture from the tissue are also expelled.Hence, the respiratory system helps release unwanted heat and water from the body.

C.
Measure the volume of a balloon filled with room temperature air; place the balloon in a freezer for an hour and measure its volume again.
D.
Measure the pressure of the air in a bicycle tire on a cold day.
Answer:
C.
Measure the volume of a balloon filled with room temperature air; place the balloon in a freezer for an hour and measure its volume again.
Hope this helps!
Measure the volume of a balloon filled with room temperature air; place the balloon in a freezer for an hour and measure its volume again would best investigate the effect temperature has on the volume of a gas. So, the correct option is C.
How volume effect the temperature of the gas?The ideal gas law states that the temperature of a gas is directly proportional to its volume. Specifically, the temperature of a gas will increase if its volume is decreased while its volume and pressure remain unchanged. If the volume of a gas is increased, its temperature will fall but its volume and pressure will remain unchanged.
This relationship can be explained by the fact that when a gas is compressed (that is, its volume decreases), the molecules are confined to a smaller area and move more away from each other and the walls of the container. Bars collide. Due to the increasing frequency of impacts, there is also an increase in kinetic energy, which increases the temperature.
So, the correct option is C.

The following statements concerning the karyotype in the diagram is true - The diagram illustrates the results of nondisjunction during gamete formation.
Karyotype
Karyotype refers to the number and appearance of chromosomes present within the nucleus of a eukaryotic cell. It is illustrated as a diagram such as given in the question.
There is no Down's syndrome as the karyotype demonstrates a normal pair of chromosome 21. In this karyotype, there is an extra X-chromosome that depicts non-disjunction during either oogenesis or spermatogenesis (gamete formation) in the parents leading to the 23rd trisomy.

Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant
produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.
It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.

why groups of animals are found on some islands but not others?
Answer:
Wilson has created the theory of the biogeographic nature of the island, which predicts that the number of species on the island depends on the balance between colonization, the evolution of the novel island species, and extinction.
Explanation:
A new DNA sequence containing 596 species of terrestrial birds from 41 island chains (archipelagos) around the world has been assembled by the researchers. The data combined sample data from their own field visits, research, and field samples from GeneBank colleagues. This information was utilized to build and employ a dynamic model that predicted international relationships that regulate biodiversity variation in their novel analysis approaches. In that, they confirmed two main components of MacArthur and Wilson's initial biogeography theory on the island.
The understanding of biodiversity on the island is important to conservation but also has implications beyond that – when imposing barriers to species dispersal it could enable us to assess better the effects of human activities, and it can contribute to a wider understanding of biodiversity around the globe.

How do divisions in the geologic time scale differ from the way we organize time using a clock?
Explanation:
The Earth's geologic past is divided into hierarchical time periods. This hierarchy comprises eons, eras, times, epochs, and ages, from largest to smallest. The Cenozoic, Mesozoic, and Paleozoic Periods are the three main divisions of the Phanerozoic.
The geological timescale is the official earth clock and differs from the way we organize time using a clock, as the planet's time is too long for us to use measures of hours.
Geologic timescalePlanet Earth is about 4.5 billion years old. To better understand its history, scientists divide geologic time into five levels of classification, called chronostratigraphic units:
EonsErasPeriodsEpochsand ages.Eons are large and indeterminate spans of time and are divided into four classifications:
Phanerozoic (last 542 million years)ProterozoicArcheanand Hadean.Of them, only the Hadean is not divided into ages. The ages are characterized according to the different positions of continents, oceans and their living beings. Within the ages are divided in the periods. Epochs, in turn, are divisions within periods and are divided into ages. According to the researchers, we currently live in the Quaternary period of the Cenozoic era.
To get a rough idea of how much the existence of the human being is a mere recent episode in Earth's geological time, we use some analogies. For example, if the entire history of the planet were summarized in the twenty-four hours of a day, the existence of humanity would have occurred in the last three seconds of that same day.
Understanding the dimension of geological time and its scales of measurement becomes a fascinating mental exercise to better understand the role of man in relation to this temporality and his role as heir of all the transformations that have taken place in terrestrial space throughout the geological ages.
