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".

Place the steps below in order from the first to happen to the last that will happen in hemostasis. Chemicals are released from the injury site and from underlying callogen. A blood vessel is severed. Blood and blood components leak out the breaks. The platelets become activated making them spiked and sticky. Fibrin forms a mesh that traps more platelets and erythrocytes, producing a clot. Fibrinogen is converted to fibrin. The smooth muscle in the vessel wall contracts near the injury point, reducing blood loss.
Answer:
A blood vessel is severed.
Blood and blood components leak out the breaks.
Chemicals are released from the injury site and from underlying callogen.
The smooth muscle in the vessel wall contracts near the injury point, reducing blood loss.
Fibrinogen is converted to fibrin.
The platelets become activated making them spiked and sticky.
Fibrin forms a mesh that traps more platelets and erythrocytes, producing a clot.
Explanation:
Hemostasis is the process by which the body prevents and stop blood loss through bleeding.
Hemostasis occurs in three steps:
1. Vasoconstriction: Once a blood vessel is severed or cut, the smooth muscles of the blood vessels start to constrict or get narrower around the severed vessel in order to reduce blood flow through it. This vasoconstriction occurs in response to chemicals released from the cut vessel and the underlying collagen.
2. Platelet-plug formation: the platelets become activated by a glycoprotein called Von Willebrand factor (vWF), which is found in plasma and begin to clump together sticking together. This is known as primary hemostasis.
3. Clot formation: in response to platelet-plug formation, several clotting factors are activated which eventually convert fibrinogen to fibrin. Fibrin is mesh-like and holds the platelets as well as red and white blood cells in place, thereby forming blood-clots over the wound.
A white flower is pp.What is its genotype?
Answer:
Explanation:
The genotype is recessive time=1/4 of the offsprings have white flowers!
Explanation:
In a broad sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. ... Humans are diploid organisms, which means that they have two alleles at each genetic position, or locus, with one allele inherited from each parent.

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.
Mrs. Underwood explained to her class her theory that people do not understand the importance of timelines until they have lived through major historical events. Why is her theory different from a scientific theory?
A scientific theory concerns only physics and is supported by mathematical calculations,
O A scientific theory concerns nature and is supported by data collected through field observations and experiments.
A scientific theory concerns popular opinion and is supported by the opinions of researchers in the social sciences
A scientific theory concerns the humanities and is supported by interpretations of artistic works
роо
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.
in the reproductive cloning of an animal the genome of the cloned individual comes from
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.

Which 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
