Question 25 1 points The ancestor of land plants is thought to be related to charophytes, a type of green algae. Why might it be advantageous for charophytes to undergo sexual reproduction? a. Charophytes, like land plants, have plasmodesmata, which need to be generated by sexual reproduction b. Sexual reproduction produces larger numbers of offspring in less time. c. They are multicellular when conditions are unfavorable, which favors sexual reproduction d. Sexual reproduction produces multicellular...

Can someone please help me to answer this question with a thorough explanation? Thank you in advance! There are almost 500 naturally occurring variants of hemoglobin. Most are the result of a single amino acid substitution in a globin polypeptide chain. Some variants produce clinical illness, though not all variants have deleterious effects. A brief sample follows. HbS (sickle-cell Hb): substitutes a Val for a Glu on the surface Hb Cowtown: eliminates ion pairs at N and C terminus of...
