Answer:
Necessary for the transport of dietary lipids. (Ans. C)
Explanation:
Lacteals are specialized lymphatic capillaries which helping in to absorb dietary fats that are present in the villi of the small intestine. With the help of bile, triglycerides is emulsified, and with the help of enzyme lipase, triglycerides is hydrolyzed, these (emulsified and hydrolyzed) results in the mixture of di, monoglycerides, and fatty acids.
The villi are finger shaped, and tiny in size which helping in to increase the surface area. Intestinal structure is known as lacteals which helps in the transport of glycerol, and fatty acids aside from the small intestine in the lymph.
Answer:
The correct answer is option d. "A region of DNA sequence upstream of a gene where transcription factors bind".
Explanation:
Cis-regulatory elements (CREs) are fragments of DNA that do not encode to a protein, but regulate the transcription of nearby genes. CREs regulation is based on binding to transcription factors. These elements are vital for the regulation of complex molecular mechanisms that involve the participation of multiple genes. Additionally, CREs could participate in pleiotropy (a single gene being responsible for the development of multiple traits), because a single transcription factor could bind to different CREs.
Answer: 30,000,000,000,000
Explanation:
Humans are complex organisms made up of trillions of cells, each with their own structure and function. Scientists have come a long way in estimating the number of cells in the average human body. Most recent estimates put the number of cells at around 30 trillion. Written out, that's 30,000,000,000,000!
Learned it in class
Answer:
I believe it would decrease
Explanation:
The high temperature will be detected by sensors—primarily nerve cells with endings in your skin and brain—and relayed to a temperature-regulatory control center in your brain. The control center will process the information and activate effectors—such as the sweat glands—whose job is to oppose the stimulus by bringing body temperature down.
