Answer:
D (proteins moving ions from low to high concentration across a cell membrane)
Explanation:
Active transport, by definition, is a type of substance transport that requires energy (typically in the form of ATP). Having said that, we can immediately eliminate B (aka water diffusion throughout the cytoplasm of a cell), as diffusion (osmosis in this case) does not require any expenditure/spending of energy. Next, we can cancel A and C because although they do require energy, there is no transport involved. Thus that leaves us with D. D is not only the answer because of the process of elimination but also b/c the ans. choice says that ions are being moved from low to high concentration, which is against the concentration gradient and thus requires energy. Hope you found this helpful! :)
<span>You seem worried that the surgery will change how others see you" is an open-ended response that encourages further discussion. The response "You seem concerned that your partner will reject you" is too specific; the nurse does not have enough information to come to this conclusion. The response "You are wondering about the effect on your sexual relations" is too specific; the nurse does not have enough information to come to this conclusion. The response "You are probably underestimating your partner's love for you" denies the client's concern and may cause feelings of guilt for questioning the partner's love.</span>
5 desert animals are camel, sand cat, desert tortoises, desert lizards and the great road runner.
<u>Explanation:</u>
- Camel has several physiological and behavioral adaptations that help them survive the extreme conditions of the desert. They have flat feet to help them spread their weight in the sand.
- They have thick eyelashes and closeable nostrils to prevent the entry of sand. They store fat on their humps that supplies energy during long journeys and has a long large intestine which increases water reabsorption.
- Sand cat is similar to the domestic cat in basic appearance but has several adaptations enabling it to survive in the desert. Their paws are covered with thick and long hairs to protect the feet from the heat. They have thick fur that acts as an insulting surface during hot days and cold nights.
- Desert tortoises have excellent water storage capacity. Their bladders are larger than normal and can carry extra water. They have strong feet which helps them to dig holes in the sand and access rainwater.
- Desert lizards can drink water through skin. They do it by a process called cutaneous water acquisition and it helps them to gather water obtained from rainfall, damp sand and pools.
- Great roadrunner has peculiar adaptations. The digestive system of the bird retrieves water from the feces as it is in the excretory canal.
