Question
The concentration of CO_2 is higher in the air than in the alveolar capillaries. The total exchange surface area is relatively large. All of the following are characteristics of adult arthropods except an exoskeleton. a heart. a coelom. Jointed appendages. hemolymph. Secondary messengers are associated with which of the following? transduction reception response both A and B both B and C Why is it so difficult to study the actions of plant hormones? They are found in small quantities in the plant. They sometimes cause different responses in different plants. We probably have not discovered all of them. Their effects are often the result of an interaction of hormones. All of the above make the study of plant hormones difficult. The most recent common ancestor of all land plants was most similar to modern-dry members of which group? red algae brown algae Charophycea Cywnobacteria golden algas All of the following are steroid hormones except androgen. estrogen. cortisol. testosterone Which of the following do all fungi have in common? meiosis in basidia coenocytic hyphae symbioses with algae sexual life cycle absorption of nutrients In which vertebrates is fertilization exelusively intermal? reptiles and mammals chondrichthyans, osteichthyans, and mammals amphibians, mammals, and reptiles chondrichthyans, osteichthyans, and reptiles reptiles and amphibians In the lysogenic cycle viral DNA is replicated along with host DNA a bacterium replicates without passing viral DNA to its daughter cells. viral DNA is destroyed and host DNA is replicated. a bacterium divides once before the lytic cycle is initiated.Explanation / Answer
65.The corret answer is : D) a coelom
Reason: Adult arthropods lack coelom.
66.The correct answer is: A) transduction
Reason: In transduction process, secondary messengers play an important role.
67.The correct answer is: A) They are found in small quantities in the plants.
Reason:The plant hormones are found in very low concentration in plants.
68.The correct answer is:C) Charophycea
Reason:This includes Charophyte green algae and thus is considered modern day member similar to common ancestor of land plants.
69.The correct answer is: C) Insulin
Reason: Insulin is a peptide hormone.
70.The correct answer is: E)Absorption of nutrients.
Reason:The nutritional mode in all fungus is through absorption.
71.The correct answer is:A) reptiles and mammals
Reason: In reptiles and mammals,fertilization is internal.
72.The correct answer is: A)viral DNA is replicated along with host DNA.
Reason: Viral DNA integrates into the host DNA and gets copied along with DNA of the host.
