Answer:
Liquids have more kinetic energy than solids
Explanation:
When a substance increases in temp, heat is being added, and its particles are gaining kinetic energy.
Answer:0.8775
Explanation:formula for gene frequency is p+q=1
where p is the dominant allele and q is the recess allele.
Given than p=0.35
P^2=0.35^2=0.1225
q=1-p
q=1-0.1225=0.8775
Answer is 0.8775
<h2>The given statement is true</h2>
Explanation:
Iron absorption occurs in the duodenum and upper jejunum of small intestine
- At physiological pH ferrous iron is rapidly oxidized to the insoluble ferric form
- Gastric acid lowers the pH in the duodenum which enhances the solubility and uptake of ferric iron
- Once iron gets inside the enterocyte it can be stored as ferritin;Ferritin is a hollow spherical protein which helps in storage and regulation of iron levels within the body
- Ferritin molecule have ferroxidase activity which helps in the mobility of Fe2+ out of the enterocyte by ferroportin
- Transferrin is the major iron transport protein which transports iron through blood
- Fe3+ binds to transferrin so Fe2+ transported through ferroportin must be oxidized to Fe3+
- Fe2+ needs to be oxidized first so that it can be transported through ferroportin
- Once iron gets inside the cell it can be used for various cellular processes
The water molecules enter a gaseous state called water vapor. So water Evaporates.
