If the dna of a certain organism has guanine as 30% of its bases, then what percentage of its bases are adenine?
serious [3.7K]
G always pairs with C...So, if there is 30% G, then there's 30% C...which is 60%...that leaves 40% A+T - and you have to split this up too - so 20% Thymine (T) and 20% Adenine (A).

SSSSS [86.1K]

The correct flowchart is energy - > atmosphere - > air pressure - > convection - > global winds. This is a very simple process as explained.

<h3><u>Explanation:</u></h3>

The energy from the sun actually heats up the land surface and the water surface of the earth. As the land gets heated up, the layer of atmosphere that is adjacent to the land and water also gets heated up. This leads to the decrease of air density as the heat causes expansion of gases. With decrease in air density, the air pressure also drops and the air from the cooler layer of atmosphere above comes to fill up the space and this heated air goes up. This causes the convection current to get set up. This causes the global winds and different oceanic currents to flow all over the earth throughout the year.

What are the adaptations that help animals to live in their habitats?
Jobisdone [24]
  • <u>Adaptations </u><u>are unique characteristics that allow animals to survive in their environment.</u>
  • <u> There are </u><u>three </u><u>types of adaptations: </u><u>structural</u><u>, </u><u>physiological</u><u>, and </u><u>behavioral</u><u>. Structural adaptations are how the animal's body functions or looks on the ou</u>tside.

What are 3 ways animals can adapt to their environment?

Animals adapt to their environment in a variety of ways; an animal's color, behavior, defense or diet, for example, may serve adaptive functions.

  • Color and Pattern Adaptations.
  • Behavioral Adaptations.
  • Defensive Adaptations.
  • Dietary Adaptations.

What is an example of an animal adapting to its environment?

  • Adaptation can protect animals from predators or from harsh weather.
  • Many birds can hide in the tall grass and weeds and insects can change their colour to blend into the surroundings.
  • This makes it difficult for predators to seek them out for food.
