Explain how observation, interpretation, and explanation are important to the study of science.
Answer:
Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing.

Compare a virus to a unicellular organism. (1 point)
O Viruses need energy, unicellular organisms do not need energy.
O Unicellular organisms have a cell membrane made from a lipid bilayer, viruses have a protein coat
O Viruses reproduce through asexual reproduction; unicellular organisms need a host cell,
O Neither unicellular organisms nor viruses respond to stimuli.
Answer:
differences : Viruses need energy while unicellular organisms donot need energy
Unicellular organism has cell membrane but virus has protein coat.
Unicellular organisms have a cell membrane that is made from a lipid bilayer whereas viruses have a protein coat which is called capsid. Unicellular organisms reproduce through asexual reproduction whereas virus need a host cell for their survival because virus use the cell engine to extract food for their survival so it is conclude that unicellular organisms have cell membrane but virus has protein coat.

Answer:
Answer: Lactic acid building up causing sore muscles
Explanation:
Got it right on the test.
An example of anaerobic respiration is lactic acid building up, causing sore muscles. The correct option is B.
What is anaerobic respiration?
Anaerobic respiration is respiration that occurs in the absence of oxygen. When we exercise or run, more amount of oxygen is needed, so there is less oxygen remaining for the reactions, these reactions occur in absence of oxygen.
Thus, the correct option is B.

A)
steroids; separate the cytoplasm from the environment
B)
waxes, prevents water loss and repels water
c)
triglycerides; make up sex hormones
D)
phospholipids, store energy
Answer:
B) Waxes, prevents water loss and repels water
Explanation:
Waxes, steroids, phospholipids, and triglycerides are types of lipids. All of them are made of Hydrocarbon chains that are hydrophobic.
Triglycerides (fats) - Storage molecules for the body's energy
Steroids - Sex hormones and cholesterol
Phospholipids - Cell membrane (Separates cytoplasm from the environment)
Therefore, Answer choice B) Waxes, prevents water loss, and repels water, is the only answer that correctly matches with the provided answers.

B. have resistance because their ancestors were exposed to this antibiotic or a similar antibiotic. C. lack resistance because their immune system needs to see the antibiotic in order to develop resistance. D. have resistance if mutations or horizontal gene transfer provide some members of the population with resistance.
Answer: A
Explanation:
Their immune system lacks the antibodies to combat the antibiotic and need to be exposed to it first before it develops.

HELPP!! (40 pts) Explain how the earth's core has impacted human life. Use evidence from the
text to support your answer.
Answer:
The earth’s core affects the shape of the ground we
walk on.
Explanation: The earth’s core is responsible for
not only the Rocky Mountains, but the formation of cities and societies that have lived there for
generations, such as Rocky Mountain National Park. It’s responsible for mountains that serve as barriers,
bringing to life divisions in culture unique to each side, while also posing a challenge to be crossed and
burrowed into, spurring on scientific innovation in the process.
The Earth's core has impacted human life in a variety of ways. As it is responsible for the generation of the earth's magnetic field and contains a history of the planet.
What do you mean by the Earth's core?The Earth's core may be defined as the innermost layer of the Earth which is very hot and dense.
The Earth's core is responsible for any geographical locations like mountains, deserts, biodiversity hotspots, rivers, etc. It gives a structural appearance to the Earth. Human life is widely impacted and depends on all of these locations for their needs. All these geographical locations determine the climate of that particular area which is responsible for those people who are living at that location. Human life takes all its requirements from this core surface only.
Therefore, the Earth's core has impacted human life in a variety of ways. As it is responsible for the generation of the earth's magnetic field and contains a history of the planet.

How does photosynthesis take place? need detailed explanation
Answer:
Photosynthesis takes place inside plant cells in small objects called chloroplasts. During photosynthesis, Plants get carbon dioxide from the air through their leaves, and water from the ground through their roots. Light energy comes from the Sun. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
