3 0

Answer:

The flow/transfer of energy would be A) sound-electrical-sound

Explanation:

When you are talking on the telephone, you speak, which produces sound. The telephone picks up this energy and converts it to electrical signals, which are then converted back to sound on the other end of the line, thus the answer to your question being A) sound-electrical-sound

Seema knows the mass of a basketball. What other information is needed to find the ball’s potential energy?
evablogger [386]
I think this is actually a physics question- 
gravitational potential energy = mass*g*height. We know mass and g is constant, so all we need to know is the height of the basketball.

Hope this helps :)

using what have you learnt about the effect of concentration gradient and surface area to volume ratio, explain the adaptations
tatiyna

Answer:

thanks

Explanation:

Leaves are adapted for photosynthesis and gaseous exchange.

They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.

When water evaporates from the leaves, resulting in more water being drawn up from the roots, it is called transpiration.

To reduce water loss the leaf is coated in a waxy cuticle to stop the water vapour escaping through the epidermis. Leaves usually have fewer stomata on their top surface to reduce this water loss.

Leaves enable photosynthesis to occur. Photosynthesis is the process by which leaves absorb light and carbon dioxide to produce glucose (food) for plants to grow. Leaves are adapted to perform their function, eg they have a large surface area to absorb sunlight.

Plants have two different types of 'transport' tissue, xylem and phloem. These specialised tissues move substances in and around the plant.

Let's bring what you have learned about the carbon cycle, photosynthesis, and cellular respiration and show how they are connect
slava [35]

Answer:

Plants absorb carbondioxide gas from atmosphere whereas respiration releases carbondioxide .

Explanation:

Carbon is present in the atmosphere in the form of carbondioxide gas which is used by the plants in the process of photosynthesis. Plants takes carbondioxide gas from the surrounding air through small openings called stomata and made their own food while on the other hand, carbondioxide gas is released from the body of living organisms in the process of cellular respiration.  In cellular respiration, food is broken down with the help of oxygen forming water, carbondioxide gas and energy in the form of ATP molecules.
