Answer:
AAT
Explanation:
A pairs with T
C pairs with G.
Thus TTA pairs with AAT
According to complementary base pairing in DNA, the complementary strand of DNA would be AAT.
What is DNA?DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

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.

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.

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.
