- ed-eyed tree frog eggs can hatch up to two days earlier than average when they detect vibrations. However, if they hatch more than two days earlier than expected due to vibrations, the embryos are typically not developed enough to survive outside of the egg. Explain how natural selection inhibited frog eggs from hatching any earlier than two days before expected hatchingWhich of the following describes the blastula development in frogs or anurans? Select the correct response: Blastocoel is more oriented towards vegetal pole. Holoblastic with equal sized blastomeres. Blastomeres are larger in vegetal pole than animal pole. Development is slower in the animal pole.Human embryos have tails which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and mammals Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate? a close evolutionary connection between humans and many other mammals a very distant evolutionary connection between humans and many other mammals a very distant evolutionary connection between humans and many other reptiles a close evolutionary connection between humans and many other reptiles
- The gender of an American alligator is determined by the temperature at which the egg incubates. A temperature of 34°C and higher produces male offspring, while a temperature closer to 30°C produces female offspring. Which statement best explains gender determination in American alligator offspring? O The gender of the offspring is determined to keep an even number of males and females in the American alligator population. O The gender of the offspring is determined to ensure a large number of mature females in the American alligator population. O The gender of the offspring is determined as a result of environmental and not genetic factors. O The gender of the offspring is determined as a result of genetic and not environmental factors. hp -> esc & 司Because many of the key mechanisms of evolution activate when sperm and egg combine, volutionary change happens faster for organisms with short life cycles (viruses, bacteria, fruit fly, yeast) compared to organisms with long life cycles (humans, elephants, tortoises). True FalseIs sexual selection or natural selection the driver for the differences between males and females? a. In the hollyhock weevil (Rhopalapion longirostre) the females a have much longer rostrum. The length of rostrum is correlated with offspring survival but not mating frequency. b. In the marine iguana species (Amblyrhynchus cristatus) on the islands near Ecuador the males often exceed expected size on a given island. Male size is correlated with survival and number of mating events.
- As a follow‑up experiment, researchers placed the Daphnia that were exposed to the Notonecta chemical cues into a tank without chemical cues. The Daphnia reproduced asexually, and the offspring developed in the tank without chemical cues. Predict the relative size of the crest height and width of offspring raised in the tank without chemical cues as compared to the parent Daphnia.Describe how changes in the ladybugs'environment may influence their survival and/or reproduction. Make sure to use the vocabulary terms adaptation, natural selection, and polymorphic.What are some of the traits present in the newt population described in the article?How might these traits change from individual to individual? (Hint: Do you think the newts are all exactly the same color or size?)
