Answer: t= -1.60
Explanation:
Let 
be the population mean weight of pigs.
As per given , we have
Sample size : n= 16
Sample mean =
Sample standard deviation : 
<em>Since the population standard deviation is not known so the test is a</em><em> t-test.</em>
Test statistic for population mean : 
(Substitute all the values.)
Hence, the value of the test statistic needed to test the null hypothesis : t= -1.60
Answer: Maltase is part of a group of intestinal enzymes called FamilyGH13 (Glycoside hydrolase family 13) that are responsible for breaking apart the α-glucosidase linkages of complex carbohydrates into simple to use glucose molecules.
Explanation: ?
Answer: Contaminants or chemicals released into the drain of bathroom or kitchen will pollute the water body where the drain discharges those chemicals.
Explanation:
The chemicals and other items that are poured down the bathroom or kitchen and drain into water sources can contaminate the water sources and will cause water pollution.
These are:
Vegetable oil
Left over food residues
spices
disinfectant
Phenol
soap
sugar
detergent or washing powder
grease or any other lubricant
shampoo
Answer:
Proteins are dynamic entities, and they possess an inherent flexibility that allows them to function through molecular interactions within the cell, among cells and even between organisms. Appreciation of the non-static nature of proteins is emerging, but to describe and incorporate this into an intuitive perception of protein function is challenging. Flexibility is of overwhelming importance for protein function, and the changes in protein structure during interactions with binding partners can be dramatic. The present review addresses protein flexibility, focusing on protein-ligand interactions. The thermodynamics involved are reviewed, and examples of structure-function studies involving experimentally determined flexibility descriptions are presented. While much remains to be understood about protein flexibility, it is clear that it is encoded within their amino acid sequence and should be viewed as an integral part of their structure.
Explanation:
<span>Pulmonary circulation is the movement of blood starting from
the heart, where deoxygenated, or carbon dioxide-filled, blood leaves from the
right ventricle and through the pulmonary valve, then into the left and right
pulmonary arteries and arrives at the lungs. During the process of respiration,
the carbon dioxide is released and oxygen is added to the blood. Then, the
pulmonary veins carry the oxygenated blood back to the heart, entering into the
left atrium, completing the circulation. The correct answer is B, pulmonary.</span>
