Answer:
With regard to iodine, beaker is hypertonic whereas with regard to starch, tube is hypertonic.
Explanation:
The beaker has higher amount of iodine solution than the tube so the beaker is considered as hypertonic solution while on the other hand, the tube has more starch concentration than the beaker so the tube is considered as hypertonic solution. In hypertonic solution, the concentration of solutes are higher than the surrounding environment or another solution. So that's why with regard to iodine, beaker is hypertonic whereas with regard to starch, tube is hypertonic.

What are some ways another kind of natural disaster could change an environment and change the selective pressures felt by a species?
Answer:
Strong volcanic eruptions and fires can temporarily change regional weather, cooling or heating the air, changing winds, or causing rain. Volcanoes, storms, and floods can kill marine animals directly, or cause long-term problems by depositing debris and affecting the temperature and salinity of water.
Explanation:
Some ways through which natural disasters could change an environment and change the selective pressure felt by a species are volcanic eruptions, wildfires, floods, droughts, storms, acid rain, etc.
What is Species?Species may be defined as the collection of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. It is the basic unit of classification and a taxonomic rank of an organism.
According to the context of this question, effective and long-lasting volcanic eruptions and fires can significantly change regional weather. Apart from this, actions like cooling or heating the air, and alterations in wind patterns and directions that typically cause rain also change an environment and change the selective pressure felt by a species.
Therefore, some ways through which natural disasters could change an environment and change the selective pressure felt by a species are volcanic eruptions, wildfires, floods, droughts, storms, acid rain, etc.

Answer: A scientific theory concerns nature and is supported by data collected through field observations and experiments.
Explanation:
Scientific theories are only established based on verified facts derived well organized research and experiments using data and other supporting evidences. Theories differ from hypothesis or philosophical sayings which lacks factual and reproducible evidences.
Mrs. Underwoods theory could best be deemed as an assertion because her theory lacks an established and reproducible evidence prepared from data or experimental research to back up or align with her theory.
Why are the layers in the rock important?
Answer:
Explanation:
Why are layers of rocks related to each other?
Layering, or bedding, is the most obvious feature of sedimentary rocks. ... This Law of Superposition is fundamental to the interpretation of Earth history, because at any one location it indicates the relative ages of rock layers and the fossils in them. Layered rocks form when particles settle from water or air.
if you had to choose between the phrase "natural selection gives organisms what they need" vs. "natural selection chooses traits that are most successful", which one would you choose? defend your answer.
Answer:
Natural selection gives organisms what they need
Explanation:
The species constantly evolve because of the changes around them. Natural selection gives organisms what they NEED in order to survive. "Natural selection produces organisms perfectly suited to their environments".
Species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".
What is Natural Selection?Natural selection is defined as the differential survival and reproduction of individuals due to differences in phenotype which is a major mechanism of evolution, a change in the genetic properties of populations over generations.
It is the process through which populations of living organisms adapt and change where individuals in a population are inherently variable, meaning they all differ in some way. This variation means that some individuals have better adaptations to the environment than others.
Thus, species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".

Answer:

Explanation:
Students are asked to pair a plant structure to its physiological function as well as give evidence for why
that structure is important for the process they describe.
• Shantal: The cambium are important for photosynthesis because they allow water into the plant
which is needed as a reactant for photosynthesis.
• Jamil: The phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves
in order to perform cellular respiration.
• Enrique: The guard cells are needed during food production because they regulate how much water
the plant retains or loses during glycolysis.
• Anne: The seeds of the plant are needed for reproductive purposes and they can be dispersed or
spread out over a large area.
Which student correctly described a plant structure, its physiological function, and gave appropriate
evidence?
O Shantal
O Jamil
O Enrique
O Anne
Answer:
Anne
Explanation:
The only student that correctly described a plant structure, its physiological functions, and gave appropriate evidence is Anne.
The seeds of plants are propagules and, depending on the kind of seed, can be dispersed over a large area from their parent plants.
The phloem of a plant is primarily concerned with the conduction of synthesized food around the body of the plant from the source of production. Hence, Jamil's description that the phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves was inaccurate.
The guard cells control the rate of evapotranspiration of water from the plant but have nothing to do with the breakdown of glucose, also known as glycolysis. Thus, Enrique's assertion was also inaccurate.

True or False: Decomposers do NOT need energy to live.
A. True
B. False
Answer:
False
Explanation:
Consumers (animals) get their energy by eating the producers and/or other consumers. Scavengers and decomposers get their energy by eating dead plants or animals. Living organisms require these nutrients to create cells, tissues and to provide energy for life processes. Thus, all living things need energy to survive.

living cellstissue organsystemorganismbasicWhich product is the result of light reactions in photosynthesis? O A. Water B. Glucose O c. Carbon dioxide OD. Oxygen
Answer:
D. Oxygen
Explanation:
Plants absorb carbon dioxide (CO2) and release oxygen for humans and animals to breathe in. Afterward, they'll release CO2 for plants to absorb, which forms a cycle.
Answer:
Oxygen
Explanation:
Both light dependent and light independent reactions in photosynthesis create glucose. But, only light dependent reactions convert carbon dioxide to oxygen.
Light independent: Carbon dioxide + water --> ATP and NADP(Energy/Glucose) and water
Light dependent: Carbon dioxide + water + light --> Glucose(ATP and NADP), water, and oxygen
The Miller-Urey experiment simulated compounds present in the atmosphere of early Earth, lightning, and the evaporation and condensation of atmospheric water. What other information about the conditions on Earth during this time period would you want to know to improve the experiment?
Answer:
The Miller-Urey experiment was conducted to simulate the conditions on Earth when life arose, and see if a chemical evolution could occur. This experiment was performed without oxygen, because they knew that if oxygen was added, the amino acids would oxidize. In particular, the experiment intended to simulate a volcanic eruption was analyzed.
Thus, particles of water, methane, ammonia and hydrogen were exposed to high temperatures and electric discharges that simulated these eruptions, during a determined period. Later, it was observed that organic compounds had emerged from this exposure, which allowed us to infer one of the hypotheses regarding the origin of life on Earth.
