Option 2 (Population of organisms change over time.
how much force is needed to make a 12 kg object accelerate at 3 m/s
what provides new variation
Answer:
Mutation
Explanation:
The main cause of variation within a population is usually through genetic mutation.
Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.
Most times, environmental influences are paramount to causing genetic mutation within a population.
Other times, it might be due to competition and some other internal factors.
Mutation can be transferred from parents to offspring in most cases.
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.

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".

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.
A whale is a mammal and a shark is a fish, but they have similar body plans. This is an example of _______.
Humans have many “good bacteria" living along their digestive tract. Not all of the food that humans eat
is fully digested. The "good bacteria" feed on the undigested food. This helps the bacteria to get
nutrients and helps the human with the digestive process. What type of symbiotic relationship does this
relationship describe?
Answer:
It would a Mutualism relationship
Explanation:
Because both humans and bacteria are benefiting from each other.

Answer:
C. Similar methods of reproduction
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.
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.
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.
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

how does the concept of apoptosis relate to sally cancer cells compared with normal cells ?
Answer:
Apoptosis is defined as a programmed cell death and plays very important role in the removal of cancerous cells. Apoptosis is the process in which cell undergoes several processes and attempt sui-cide. Apoptosis do not cause any harm to human cells as it removes only unwanted cell.
Apoptosis can prevent cancerous cells by telling unwanted growth of cell to self destruct. Cancer cells are formed due to proliferation of cells and ignore the signals of self destruction to prevent apoptosis.
In Sally's case also, cancer cells ignored the signal of apoptosis and a tumor was found in her colon.
