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

Choose a statement that explains why competitive exclusion occurs between different species.
Limited resources are easily shared.
There are unlimited resources in the ecosystem.
Competition decreases the health of all animals.
One competitor is best at using a limited resource.
The statement "Limited resources are easily shared" is the one correct about the competitive exclusion between different species.
What is competitive exclusion?It is the result of the competition in which a species is expelled by another more efficient species from a part of the available habitat.
Characteristics of the competitive exclusionThe competitive exclusion principle states that two species cannot occupy the same ecological niche in the same habitat.If there are limited resources, eventually one species will exclude the other, given a certain period of time, through “competitive exclusion”.Therefore, we can conclude that the competitive exclusion states that two species occupying the same niche cannot coexist in the long term since they would enter into competition for limited resources.

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.

C) Runoff, precipitation, evaporation, melting, condensation
D) Evaporation, condensation, precipitation, runoff, collection
Explain why
Answer:
D) Evaporation, condensation, precipitation, runoff, collection
Please give me brainlyest
Explanation: The water cycle shows the continuous movement of water within the Earth and atmosphere. System that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Then I does runoff and creates a new water source or goes back to a water source.

What is the water cycle?
A) A process by which water moves from cloud to cloud in the sky
B) A process by which water is absorbed into soil on Earth's surface
C) A process by which water moves from Earth's surface into the sky and back again
D) A process by which wind washes large amounts of water onto land from the oceans
explain why
according to me the answer is
C) A process by which water moves from Earth's surface into the sky and back again
explanation:the water becomes water vapour due to heat and becomes light in then it goes to higher altitude and cools down and again becomes drops of water which are heavily to hold in air so it starts raining and it comes again to ground and then again heat happens it turns in vapour cools down and moves to earth's surface (in form of rain,snowfall) and this process goes on going continuously this is called as water cycle
SO ur answer is
C) A process by which water moves from Earth's surface into the sky and back again
Answer:
c
Explanation:
A process by which water moves from Earth's surface into the sky and back again

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.

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".

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.
