About "two-thirds" of the mass of this cell is water :)
Answer:
Hello!
The answer is D) Homeostasis
Explanation:
Homeostasis:
<em>The regulation of a cell or an animal's internal environment in response to fluctuations in the external environment is called homeostasis. </em>
Homeostasis is crucial to maintain an optimum environment for cell structures to work effectively.
In this case, the jackrabbiit's circulatory system is responding to fluctuating temperatures. In hot days, the body is at risk of heating up above optimum temperature which could hamper body functions. Therefore, the blood flow to the ears is increased to facilitate heat loss.
In cold temperatures, the blood flow to the ears is decreased to conserve heat for vital body organs. The blood flow is directed to the core of the body to protect the heart, lungs, liver and brain.
Answer:
The reference value that is expressed as a percentage of total calories is called as % daily value.
Explanation:
The % daily value tells about the the nutrients which are present in a single serving of food. They are mostly present on the Nutritional Fact Label for foods. The standard for the % daily value is set to 2000 calorie. 2000 calories are required for a healthy adult diet. But even if a person has a calorie uptake lower or higher then that, he/she can still use the % Daily Value as a guideline.
For example, If 2% vitamin C is written on a label than it defines that one serving of that product supplies 2% of the vitamin C that you require each day.
Answer: Recessive Gene. Homo zygote Allele.
Explanation:
Each gene is composed of two alleles. Alleles can be Dominant or Recessive. A Dominant gene is always expressed on the Phenotype (XX/Xx); A Recessive gene expresses on the Phenotype if both alleles are the same (xx).
In this statement, it's implied that the gene that codes for "blue-eyes" is recessive, since both parents had to provide the same allele for it to express.
