Answer:
C
Explanation:
The main mechanisms of homeostasis are body temperature, body fluid composition, blood sugar, gas concentrations, and blood pressure. These are all things that involve "keeping a relatively constant internal environment in the body".
Rabbit, insect are biotic meaning living.
The statement given in this question is TRUE; Some animals in grassland can obtain the water they need from plants.
Grassland is a biome that is characterized by wide range of temperature and uniform distribution of rainfall all through the year. The major plants found in the biome are grasses and herbs. The soil in the biome is not fertile enough for trees to survive there. Different animals can be found in the biome and some of the animals has drought resistance capacity. Some of these animals obtain their water requirement from the grasses, which they consume.
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.
Answer:
False
Explanation:
Introns need to be removed precisely because the reading frame will be shifted if removed even single nucleotide too many or leaving an intronic nucleotide in the spliced mRNA .
Extra amino acids will be inserted if large pieces of introns are left in the mature messenger RNA.
In both cases, aberrant protien will be produced if the RNA splicing is not precise, hence they are needed to be removed by precision.
