The purpose of the lab is to teach how to make careful experimental observations and how to think about and draw conclusions from such data.
What are the benefits of a lab?Laboratory experiences may enhance student understanding of specific scientific facts and concepts and of the way in which these facts and concepts are organized in the scientific disciplines.
Laboratory is a place where scientific research and development is conducted and analyses performed, in contrast with the field or factory. Most laboratories are characterized by controlled uniformity of conditions (constant temperature, humidity, cleanliness).
The different purposes for which laboratory tests are ordered (diagnosis, monitoring therapy, and screening) and the operating characteristics required for each purpose. The "normal" test result and its meaning.

Answer:
I asked my friend on my phone
Explanation:
1)The early atmosphere was probably mostly carbon dioxide, with little or no oxygen. There were smaller proportions of water vapour, ammonia and methane. As the Earth cooled down, most of the water vapour condensed and formed the oceans. (cool)
2)What information can climatologists learn from fossils? Fossils of plants and animals can show adaptations that organisms had for a particular type of climate that existed millions of years ago.

Photosynthesis and cellular respiration form a cycle. A cycle is a sequence of events that repeats itself over and over again.
In your own words, explain how photosynthesis and cellular respiration form a cycle. Include details about the organisms that perform photosynthesis and cellular respiration, and the materials involved.
Your response should be at least 3 sentences long.
Answer:
Photosynthesis changes over carbon dioxide and water into oxygen and glucose. Glucose is utilized as food by the plant and oxygen is a result. Cell breath changes over oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are side-effects and ATP is energy that is changed from the cycle.
Explanation:
what role does glucose in oxygen play in cellular respiration?
A. They are reactants because they are present before the reaction.
B. They are reactants because they are present after the reaction.
C. They are products because they are present before the reaction.
D. They our products because they are present after the reaction.
Answer:
Answer is D
Explanation:
because glucose is made during respiration

What are rotating air currents circulating around a vertical axis inside a supercell?
Answer:
Supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes. They are most common during the spring across the central United States when moderate-to-strong atmospheric wind fields, vertical wind shear (change in wind direction and/or speed with height), and instability are present. The degree and vertical distribution of moisture, instability, lift, and wind fields have a profound influence on convective storm type, including supercells, multicells (including squall lines and bow echoes), ordinary/pulse storms, or a combination of storm types. Once thunderstorms form, small/convective-scale interactions also influence storm type and evolution. There are variations of supercells, including "classic," "miniature," "high precipitation (HP)," and "low precipitation (LP)" storms. In general, however, the supercell class of storms is defined by a persistent rotating updraft (i.e., mesocyclone) which promotes storm organization, maintenance, and severity. More information concerning environmental conditions and the structure of classic and HP supercells is given below. WSR-88D Doppler radar imagery showing the evolution of some supercell events across Kentucky and south-central Indiana are available.

What are some prey physical characteristics?
Answer:
Prey animals often rely on escape as their form of protection. Therefore, they must have a well-developed sense of sight, hearing, and smell so they can detect the presence of a predator in enough time to escape. Sight: Prey animals need all-around vision to see advancing predators.

What would be a possible disadvantage of asexual reproduction?
Ability to reproduce in the absence of a mate
Results in low genetic variation of the species
Allows for more genetic variation in the offspring
Takes less time to produce offspring
A possible disadvantage of asexual reproduction is that it results in low genetic variation of the species. Since asexual reproduction involves a single parent, the genetic material of the offspring is identical to that of the parent.
What is the meaning of the advantageous mutations ?
This means that any advantageous mutations or adaptations that could arise from sexual reproduction and genetic recombination will not occur in the offspring.
Low genetic variation can make a species more vulnerable to environmental changes or disease outbreaks, as there is less genetic diversity to help the species adapt and evolve.
Additionally, asexual reproduction can also increase the risk of genetic disorders and diseases. With sexual reproduction, there is a mixing of genetic material from two different individuals, which can help to weed out harmful mutations.
However, in asexual reproduction, any harmful mutations in the parent's DNA will be passed down to the offspring without any opportunity for them to be removed or diluted through genetic recombination.
Finally, asexual reproduction can lead to the accumulation of deleterious mutations over time. Since there is no genetic recombination in asexual reproduction, mutations that are not necessarily harmful in a heterozygous individual can accumulate over time, leading to the expression of harmful recessive alleles in homozygous individuals.
This can reduce the overall fitness of the species and make it more vulnerable to environmental pressures.

How does earth's position in space affect water on earth?
Answer:
The Earth's position affects the water because the sunlight from the sun can impact the temperature of the water. It heats the water ethics and the land around it. When the Earth is facing the moon (nighttime), it cools the ocean creating a soft reaction.
Explanation:
While Earth orbits the sun, the planet is simultaneously spinning on an imaginary line called an axis that runs from the North Pole to the South Pole. It takes Earth 23.934 hours to complete a rotation on its axis and 365.26 days to complete an orbit around the sun.

Does asexual reproduction involve the formation of gametes? Explain your answer
Asexual reproduction, the simplest and most primitive method of reproduction, involves a single parent and produces a clone, an organism that is genetically identical to the parent. Haploid gametes are not involved in asexual reproduction. A parent passes all of its genetic material to the next generation.
Answer:
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction, either from from a single cell or from a multicellular organism, inherit the genes of their single parent.
