Answer: D producer
Explanation: The answer has to do with trophic levels. As you probably know, the organisms at the base of the food chain are photosynthetic; plants on land and phytoplankton (algae) in the oceans. These organisms are called the producers, and they get their energy directly from sunlight and inorganic nutrients.
Answer:
Producers
Explanation:
The first trophic level in a food chain consists of producers. As the name says, they are able to take in sunlight and convert it into chemical energy. Hence can use the energy directly from the sun due to special pigments on their body. Examples: Green plants.

What new information do you feel like you missed? If you are having trouble recalling reread to clarify. The Big Bang theory.
The information about the big bang theory is everything in the cosmos was compressed into a singularity, a point of infinite heat and density, around 13.7 billion years ago. Our cosmos suddenly began to expand explosively, expanding faster than the speed of light.
According to the Big Bang theory, the Universe's present and past matter both originated at the same moment, around 13.8 billion years ago. At this point, all matter had been gathered into a singularity, which was a tiny small ball with infinite density and extreme heat.
Never was The Big Bang Theory canceled. Jim Parsons' unwillingness to extend his $50 million deal for seasons 13 and 14 had a significant impact on the choice. He loved playing Sheldon Cooper, but soon he became tired of it and was afraid of what life had in store for him outside of the sitcom.
The Big Bang theory's basic tenet is that the cosmos began at a single location some 13.8 billion years ago. Georges Lemaitre put forth the Big Bang idea in 1927. Georges referred to it as the hypothesis of the primordial atom rather than the Big Bang idea.

P, S, and Surface waves differ in their propagation direction, velocity, deepness, and in the materials through which they transmit. A) P waves push and pull in the same direction as the wave, and S waves move up and down.
What are the types of seismic waves?There are three types of waves,
P waves ⇒ consist of the transmission of the rock's compressions and rarefactions in the same propagation direction. These waves can be transmitted in the interior of the Earth.P waves are the fastest in moving and can be transmitted through different materials, liquid or solid.
S waves ⇒ they move in a perpendicular direction to the disturbance propagation direction. These waves can also be transmitted in the interior of the Earth.S waves are slower and can not be transmitted through liquid masses.
Surface waves ⇒ They can only propagate through the most superficial layers of the Earth. Their amplitude decrease with depth.Surface waves are the slowest ones.
Due to the difference in speed, the first recorded waves during an earthquake are the P waves, followed by the S waves, and finally, the surface waves.
The difference in waves' speed is used to determine the location of the earthquake focus and the Earth's structure.
According to this framework, we can assume the correct option is A)
P waves push and pull in the same direction as the wave, and S waves move up and down.

Many neurons have only a single axon, but many terminals at the end of the axon.How does this end structure of the axon support its function
Answer:
How does this end structure of the axon support its function? A single axon means that a neuron can only send one signal at a time (one electrical impulse down the length of the axon). However, since the axon has multiple terminals it can send the signal to several other cells at once.

A population has the following genotype frequencies: AA = 15%, Aa = 35%, aa = 50%.
What is the frequency of the A allele?
What is the frequency of the a allele?
Remember these two equations,
[tex]p + q = 1[/tex]
[tex]p^{2} +2pq+q^{2} =1\\[/tex]
where,
[tex]p[/tex] = frequency of the population's dominant (A) allele
[tex]q[/tex] = frequency of the population's the recessive (a) allele
[tex]p^{2}[/tex] = percent of homozygous dominant (AA) individuals
[tex]q^{2}[/tex] = percent of homozygous recessive (aa) individuals
[tex]2pq[/tex] = percent of heterozygous (Aa) individuals
As given in the question,
the frequency of the "AA" genotype = 35% the frequency of the "aa" genotype = 50%Therefore, the frequency of "A" allele is,
AA = 35% which means that [tex]p^{2}[/tex] = 0.35, by definition.
If [tex]p^{2} = 0.35[/tex] , then [tex]p =\sqrt{0.35} = 0.59[/tex], again by definition. Since p equals the frequency of the A allele, then the frequency of A allele is 59%.
And, the frequency of the "a" allele is,
Since p = 0.59, and p + q = 1, then q = 0.41;
The frequency of a allele is by definition equal to q.
[tex]q = 1- p\\ q = 0.41[/tex]
So, the frequency of the "a" allele is 41%.
Hence the correct answer is, A = 59% and a = 41%.

Humans have an omnivorous diet. Suggest how the human digestive system is adapted
to break down the different types of food that humans eat.
Human beings are omnivores.
The term "omnivores" refers to generalized feeding i.e., they can consume both plants and meat. They have specialized adaptations for gathering, eating, and processing food that contains both plant protein and animal protein. McArdle goes on to say that omnivores are primarily "opportunistic" feeders that take advantage of food opportunities in order to survive. They exhibit more universal physiological and anatomical characteristics. One such feature is the human dentition (set of teeth). It proves that the human diet is by nature omnivorous and not herbivorous given the presence of canine teeth for tearing flesh and molars for grinding and chewing. Our digestive system is shorter than that of a herbivore and longer than that of a carnivorous animal. A characteristic of omnivores is this. Vegetation requires a longer digestive system as that of herbivores to be fully digest than plant based diet. Meat is however, easily broken down. Nevertheless, consuming animal protein is not necessary for humans. It's up to you what you do.Hence, human dentition and length of the digestive tract are examples that suggest that humans are adapted to have an omnivorous diet.

16. Marc, a first-year college student, starts out on a
backpacking trip in southern New Mexico. It is September,
so the daytime temperatures are quite high, and the
desert air is very dry. He has a portable water filter to treat
river and stream water that he finds on his planned route
through the Gila wilderness. On the second day of his
week-long trip, Marc's water filter breaks. He is afraid of
contracting giardiasis (a protozoal disease spread through
water contaminated by animal feces), so he drinks only the
small amount of water that he can boil on his camp stove
at night. By the fifth night, Marc is feeling weak and thirsty,
and starts to hike out. He makes it to a local highway
and collapses. A passing motorist calls 911 for an
ambulance.
Apply Your Knowledge
a. Given that Marc has sweated a lot, and that sweating
causes the loss of more water than solutes, what has
happened to the solute concentration of Marc's blood
as a result of his dehydration?
b. From the solute concentration of Marc's blood, what
is likely to be happening to his body cells that are in
contact with his blood and related fluids (e.g., lymph
and cerebral spinal fluid)?
c. The paramedics have three saline solutions available.
The first is a "normal" isotonic saline solution (0.9%
NaCl), the second is a hypertonic saline solution
(3% NaCl), and the third is a "half normal" saline
solution (0.45% NaCl). Which one would you use to
treat Marc? Why?
a) Marc's blood now has a higher solute concentration than usual since he has lost more water than solutes. b) Marc's blood has a greater than usual solute concentration, which means that any cells in touch with it are probably osmotically losing water and starting to shrink.
c) Marc has to have his blood volume increased and his present solute concentration lowered (back to a normal concentration). Therefore, the "half normal" saline is most likely your best option. It will increase volume, but when mixed with his concentrated blood, its solute concentration will revert to normal because it is less concentrated than usual.
The amount of a solute per unit volume of a solution, or the concentration of a chemical species in a solution, is expressed as a solute's molar concentration. The most common unit used in chemistry to express molarity is the number of moles per liter, represented by the unit sign mol/L or mol/dm3 in SI units.
The thing that dissolves in a solution is referred to as a solute. In fluid solutions, the solvent is more prevalent than the solute. A chemical solution's concentration is a measurement of the solute content in relation to the solvent content.
In comparison to the solute concentration inside cells, a hypotonic fluid has a lower solute concentration. A red blood cell will experience a net inflow of free water when it is placed in a hypotonic solution.

Describe how plants leaves are adapted for obtaining carbon dioxide for photosynthesis.
For gas exchange and photosynthesis, leaves are suited. Since they have a wide surface area and stomata, which allow carbon dioxide to enter the leaf and oxygen to exit, they are well equipped for photosynthesis.
The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
The main purpose of photosynthesis is to transform solar energy into chemical energy, which is then stored for later use. This mechanism primarily provides energy to the planet's life systems.
The C3, C4, and CAM pathways are the three basic categories of photosynthetic pathways. They all use the Calvin cycle to convert CO2 into sugars, but each pathway does so in a somewhat different way.
