light-dependent reactions
light-independent reactions
Explanation:
Photosynthesis begins when light strikes Photosystem I pigments and excites their electrons. The energy passes rapidly from molecule to molecule until it reaches a special chlorophyll molecule called P700, so named because it absorbs light in the red region of the spectrum at wavelengths of 700 nanometers.

A cross between a yellow snake and a blue snake produces offspring that are all green. What type of inheritance is this?
Answer:
co dominance
Explanation:
codominance is a type of inheritance in which both allels are dominat over each other and the two allels are expressed to an equal degree in an offspring,that is why the cross between yellow and blue snake give another green colour offsprings in stead of giving all blue or all yellow offsprings depending on which allel is dominant.
as example we can take human blood group AB which is inherited from blood group A and B and both allel A and B are dominant over each other.

How might it be possible for a child to show a trait that neither of the parents showed?
A person can only show a recessive trait if both of their parents carried at least one copy of each of the recessive allele. The parents do not need to show the trait, as one copy is not enough to reveal it, but they must both carry it.

Bedrock in the area of Binghamton, New York, consists of?
a)plutonic igneous rock
b)sedimentary rock layers
c)faulted and tilted volcanic rock
d)folded metamorphic rock
Answer:
b)sedimentary rock layers
Explanation:
New York is composed of sediments that have metamorphed around 400 to 500 million years ago during the Acadian and Taconic orogenies.
Bedrock in the area of Binghamton, New York, consists of sedimentary rock layers. So, the correct option is B.
What are sedimentary rock layers?The formation of sedimentary rocks involves the accumulation or deposit of mineral and organic particles at the Earth's surface, following by cementation. The mechanisms that lead to the accumulation of these particles are collectively referred to as sedimentation.
Sediment refers to the little particles that make up sedimentary rocks and can be either geological detritus (nitrogen and phosphorus) or biological detritus (organic matter). Sandstone, limestone, and mud are examples of typical sedimentary rocks.
These rocks frequently begin as sediments that are transported by rivers, then are dumped in lakes and oceans. The sediments become dry and cement together to form rock when they are buried. Volcanic ash can be found in tuffaceous sandstones. Bedrock in the area of Binghamton, New York, consists of sedimentary rock layers.
Therefore, the correct option is B.

Some adaptations are helpful in one environment, but would be harmful in other environments. Ex) Thick fur, helpful in cold environment, but harmful in hot environments
Answer:
Thin fur is helpful in hot environments, but harmful in cold environments
The statement "Some adaptations are helpful in one environment but would be harmful in other environments. Ex) Thick fur, helpful in cold environments, but harmful in hot environments, is true.
What are harmful adaptations?Because they might alter how the body normally functions, some adaptations can be toxic or damaging to an organism. These are the kinds of maladaptations that can alter a population. They develop as a result of mutations or adjustments to the population's genetic makeup.
An organism adapts when it undergoes changes throughout time, frequently as a result of genetic mutations that happen by chance and are handed down to succeeding generations. Many diverse creatures have structural or behavioral adaptations that are advantageous to them physically.
Therefore, the statement is true.

Answer:
1. is the wave crest
2. is the wave trough
3. is the amplitude
4. is the wave length
Explanation:
1. crest point on a wave is the maximum value of upward displacement within a cycle.
2. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
3. distance between two successive crests (or troughs) is the length of the wave or wavelength.
4. amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.

1. artificial selection
2. genetic drift
3. natural selection
4. genetic modification

Answer:
2. Genetic Drift
Explanation:
Because it's simply by chance not on purpose or because their stronger.
Term used to describe the phenomenone where only black and grey rabbits survive and rest are killed randoml is called Genetic Drift..
What is genetic drift?As a result of a chance or random event, the frequency of an allele in a population drifts over time compared to the frequency of the other alleles. this is termed as genetic drift. Here, the rabbits with other coat colors were randomly killed off due to the disease which increased the frequency of the black and grey coat allele and hence the population drifts from multicolored coats to only black and grey colored rabbit coats.Hence the correct option here will be 2. Genetic Drift
other options are incorrect because:
Artificial selection is inducing the desired traits artifically which is not possible because the disease was a random event and not induced by humans.Natural selection is the survival of the fittest of the alleles and elimination of less fitter alleles. here it is not mentioned whether Black and grey coats were more fitter to survive than other coatsGenetic modification is a human made procedure and did not occur here.learn more about Genetic Drift here:

Influenza (The Flu)
Poodles
Answer:
Influenza (The Flu)
Explanation:
Influenza (the flu virus) is a real-life example of natural selection that is most evident during an annual time period when the influenza virus infection peaks. The repeated or cyclical nature of flu outbreaks is caused by the natural selection of the virus for traits that allow it to evade the immune system and replicate, a process that actually results in new distinct strains of influenza virus.
