Help? ASAP pleaseeeeeeee
Answer:
Homologous structures define similarly structured body parts among organisms that serve different functions. They show common ancestry; an example would be a human arm and horse leg (both made of bone, but different uses).
Analogous structures define differently structured body parts that serve the same function. They do NOT show common ancestry. An example would be a whale fin & dolphin fin; one is made of bone and the other cartilage, but they are both used to swim).

Which individual is a producer?
a host who seats customers in a busy restaurant
O a mother who demands quality produce for her family
O a farmer who grows only what his family needs to survive
© a student who builds a bookcase from bricks and boards
A
The individual who can be referred to as a producer is a farmer who grows only what his family needs to survive. Thus, the correct option is C.
Who is a producer?In a food chain, the producers are the organisms which can produce their own food without the help of other organisms. Generally, plants are called the producers of an ecosystem because they produce their own food and gain sustenance from the process of photosynthesis. The process of photosynthesis allows plants to produce food such as glucose (carbohydrate) which is a sugar energy. The breakdown of glucose results into formation of energy in the form of ATP (Adenosine Triphosphate).
The farmers can be referred to as producers as they are growing their own food.
Therefore, the correct option is C.

Think of a common pet or other familiar animal and identify three examples of structural adaptations it has. Explain why these adaptations are useful. Then identify a physiological adaptation in the animal and describe how it could help the animal survive or reproduce.
Structural adaptations are biological characters of an organism like the bill on a bird or the fur on a bear. Other adaptations are behaviour.
Define adaptation?Adaptation, the method by which a species becomes adapted to its surroundings; it is the outcome of biological selection's acting upon heritable divergence over various generations.

Answer:
I have observed my pet cat and my findings are as follows:My cat’s ears are long, because this helps in heat radiation in our warm climate.Due to the warm climate, my cat sheds a lot of its fur to stay cool.My cat has sharp teeth and claws to catch and eat its prey. This may be because cats belong to the lion family, and they evolved to hunt their own prey.The fact that my cat has fast-growing nails that can be kept sharp is a physiological adaptation, which has helped cats scratch off predators and thus better their survival chances. In this case, the sharp nails are structural but the fast growth is physiological.

PLEASE HELP ME FAST. How would a reduction of carbon dioxide emissions affect the oceans? Select the two correct answers.
It would reduce ocean temperatures.
It would increase ocean temperatures.
It would lower the pH of the oceans.
It would raise the pH of the oceans.
Answer:
It would lower the pH of the oceans.
Explanation:
When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean's pH (a measure of how acidic or basic the ocean is) drops. Even though the ocean is immense, enough carbon dioxide can have a major impact.
CO2 emissions are also making the ocean more acidic, making many marine species and ecosystems increasingly vulnerable. Ocean acidification reduces the ability of marine organisms, such as corals, plankton and shellfish, to build their shells and skeletal structures.

Which two statements best describe how jet streams affect climate?
A. They shift the direction of ocean currents, allowing them to affect weather on the continents
B. They influence the temperature of the ocean
C. They influence the pattern of storms
D. They shift north in the summer, allowing warm air masses to move further north
Answer:
A
Explanation:
Jet streams shift the direction of ocean currents, allowing them to affect weather on the continent and influence the pattern of storms.
What is jet stream?Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere.
These bands of strong wind can cause a change in the direction of the ocean currents, there by affecting the climatic condition of a particular geographical location.
Thus, Jet streams shift the direction of ocean currents, allowing them to affect weather on the continent and influence the pattern of storms.

Look at the food web shown below. which organisms get energy from producers?
a. squid
b. zooplankton
c. sperm whales
d. phytoplankton
Trophic webs involve energy transference through different organisms occupying different levels. These are producers, consumers (herbivores and carnivores), and decomposers. Option B. Zooplankton
What is a trophic web?The trophic web is the interaction between different organisms involving the transference of energy when some of them feed on the other ones.
The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
• The first link corresponds to a producer organism -autotroph-.
• The following links are the consumers -heterotrophs-: herbivores and carnivores.
• The last links are the decomposers that degrade organic matter from dead organisms.
Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
In this trophic web, we can see that the producer is phytoplancton (first link).
Phytoplancton is eaten by zooplankton and shrimp (second link). They are primary consumers that feed on phytoplancton.
The correct answer is b. zooplankton.
a. squid ⇒ They get energy from shrimp
b. zooplankton ⇒ They get energy from phytoplankton
c. sperm whales ⇒ they get energy from squids
d. phytoplankton ⇒ they get energy from sunlingh.

Why do the colors in the light spectrum bend at different angles when they pass through a prism?
The colors in the light spectrum have the same wavelength.
The colors in the light spectrum have different wavelengths.
The colors in the light spectrum have different refractive indices.
The colors in the light spectrum have the same refractive indices.
Answer:
Since the differences in the refraction index between the air and the glass, light bends once it enters the prism. Since the sides are angled the light bends even more when it leaves the prism.

What type of water pollution can cause genetic mutations miscarriages, birth defects, and certain kinds of cancers?
A: Explosives
B: Sediment
C: Radiative material
D: Thermal
Radiative material can cause genetic mutations miscarriages, birth defects, and certain kinds of cancers. So, the correct option is (C).
What are Radiative materials?Radionuclides also called radioactive materials are defined as the class of chemicals where the nucleus of an atom is unstable which achieves stability through changes in the nucleus such as spontaneous fission, emission of alpha particles, or protonation of neutrons or reverse conversion.
Some examples are uranium and thorium, two radioactive elements that occur naturally in the Earth's crust. Over billions of years, these two elements slowly change forms and produce decay products such as radium and radon. These materials can cause cancer, genetic defects etc.
Radioactive Materials Radiation can damage the DNA in our cells where high doses of radiation can cause acute radiation syndrome (ARS) or cutaneous radiation injury (CRI). High doses of radiation can cause cancer in later life.
Thus, Radiative material can cause genetic mutations miscarriages, birth defects, and certain kinds of cancers. So, the correct option is (C).
