How can we justify the conservation of energy using "system/surroundings" terminology for an open, closed, and isolated system?
Answers
Answer:
Closed systems do not exchange energy with the environment, while open systems do.
Explanation:
The cause of this is because closed systems are made up of an insulator that surrounds them and isolates them from the environment or adjacent environment.
This insulation prevents heat from being taken in or transferred from the surroundings as in the case of open systems.

How can we justify the conservation of energy using “system/surroundings” terminology for an open, closed, and isolated system?
Answers
Answer:
Energy can not be created nor destroyed.
Explanation:
Conservation of energy refers to the statement that energy can't be created nor destroyed, it can only be transformed into another form of energy. For example, if a pendulum swing to and fro motion, the kinetic energy is converted into potential energy. A closed system can exchange energy with its surroundings and transform that energy into heat and work. Total energy of an isolated system remains constant because no energy go out from the system.
If you find a reptile fossil buried and lithified among mud and decayed plant material, what type of depositional environment might you infer while the animal was still alive?
Answers
Answer:
The correct answer is - swamps/bog

Swamps or bogs are characteristically similar as they both area are known for the poor soil or muddy soil due to the quiet water conditions which is acuumulate by the precipitation mainly. These are have high peat content where mud and decaying or decomposing plant material found.
Bog or swamps are form due to the hundered years of decomposition or decys in plants and plants materials. As it stated that the reptile fossil buriiend lithified among mud and decayed plant material the environment must be bog or swamp.

Unlike experimental Science which seems to build knowledge through directly observing and measuring of objects and phenomenon by scientists.
A good understanding of experimentation is important here.
The amino acid substitution of Val for Glu in Hemoglobin S results in aggregation of the protein because of _____ interactions between molecules. covalent disulfide hydrogen bonding hydrophobic ionic
Answers
Answer:
hydrophobic interactions
Explanation:
Hemoglobin S (Hb S) is an abnormal type of hemoglobin where red blood cells become sickle-shaped and these elongated cells have difficulty to pass through small blood vessels. This type of hemoglobin is caused by a substitution (Glu>Val, GAG>GTG) in a β-globin gene variant. When the normal sequence is altered, a different amino acid is synthesized and it modifies the interactions between side chains by hydrophobic interactions, thereby affecting protein folding.

Describe how the composition and structure of the atmosphere insulates the planet and protects organism.
Answers
Answer: because of its layers
Explanation:
The atmosphere protects life on Earth from incoming ultraviolet (UV) radiation, keeps the planet warm through insulation, and prevents extremes between day and night temperatures.
What is Atmosphere?
An atmosphere is defined as the layer of gas or layers of gases that envelop a planet, and are held in place by the gravity of the planetary body where the planetary atmosphere is present when gravity is great and the temperature of the atmosphere is low.
The Earth's atmosphere extends up to 10,000 kilometers above the surface of the planet, which merges into space.
Beyond the chemical composition which is necessary for life, the composition of the atmosphere in different thermal regions produces weather patterns that in turn determine climate while the upper atmosphere and its ozone layer protect living organisms on Earth from highly harmful UV-B radiation.
Thus, the atmosphere protects life on Earth from incoming ultraviolet (UV) radiation, keeps the planet warm through insulation, and prevents extremes between day and night temperatures.

If 35% of the bases in a region of the Drosophila genome are guanine, what percentage in that region are cytosine bases?
Answers
Answer:
The correct answer is - 35%.
Explanation:
According to the rule of Chargaff the amount of adneine is equalls to thymine and the amount of guanine is equalls to cytosine in DNA. In a double-stranded DNA Adenine pairs with Thymine and cytosine pairs with Guanine.
So, Percentage of Adenine = percentage of Thymine
and, percentage of Cytosine = percentage of guanine
we know, percentage of guanine = 35%
Thus, percentage of Cytosine will be 35% as well.
