Answer:
C
Explanation:
In this question, we want to select which of the options that correctly attributes recent changes in climate to human activities
The correct answer is that global climate models can only reproduce recent temperature increases when anthropogenic green house gas emissions are included as forcing
What we have here is that for the models to show a pattern of temperature increase that we have seen recently, there must be a substantial effort by humans to have increased green house gases emission as a direct result of their activities
So this clearly put in the pattern detection of temperature increase by the model as a result of human actions thereby directly attributing what the model has developed as a result of what men has put into action
Answer:
Vitamin C
Explanation:
The following symptoms are found in the disease known as scurvy which is characterized as a vitamin deficiency disease caused by skin rashes bleeding gums, joint pain, and stiffness more. It is caused by Vitamin C also known as ascorbic acid plays various roles in the development and growth and repair of the body cells and tissues. It is a water-soluble vitamin and deficiency of the vitamin result in scurvy or skin disease.
Answer:
The mRNA for an Alzheimer-related gene is 2400 nucleotides long when isolated from neurons, but 2900 nucleotides long when isolated from glial cells. Genomic DNA isolated from the two cell types show the identical nucleotide sequence. the mechanisms that best accounts for the difference in the sizes of the mRNAs is the alternative slicing mechanism.
Explanation:
A controlled process during gene expression that results in a single gene coding for multiple proteins is referred to as alternative splicing.
During this process, particular exons of a gene may be included within or excluded from the final, processed messenger RNA (mRNA) produced from that gene.
Thus, the mechanisms that best accounts for the difference in the sizes of the mRNAs is the alternative slicing mechanism.
Answer:
Feedback mechanism that maintain homeostasis
Explanation:
This is because homeostasis is the ability to maintain internal environment and therefore a person with anhidrosis cannot sweat and it's body cannot cool because homeostasis is not maintained. It has effect on the negative feedback mechanism that maintain homeostasis because negative feedback can increase or decrease response to stimulus and inhibiting the stimulus ability to continue. This decrease the ability of the body to response to stimulus of heat which make to body to bring about cooking.
The axons that cross from one side of cord to the other before reaching gray matter are the gray commissures. The white columns are interconnected by the anterior white commissure, a region where axons cross from one side of the spinal cord to the other. The white matter between the anterior and posterior columns on each side makes up lateral white column. Each column contains tracts whose axons share functional properties.
