Answer:
Frogs have smooth or slimy skin that is moist, whereas toads have thicker, bumpy skin that is usually dry. All toads are poisonous, while frogs are not.
Wasps laying eggs inside hornworms and after the eggs hatch, the wasp larvae feed on the hornworm is the example of parasitism.
Explanation:
There are five types of relationships in an ecosystem. One of the relationships is parasitism. When we define ecosystem, we talk about the kind of interaction that there is between two or more different species.
Parasitism is the type of interaction between two species, in which one species, most likely a parasite, latches itself onto the other species. That other species then becomes a host to the parasite. After latching itself, it becomes dependent on it's host for resources like food and shelter. But, in this type of relationship, the host species is harmed for resources while the parasite species gains strength over time.
Answer:
A. A genetically engineered crop that is resistant to insect pests could also harm helpful insects.
B. Crops can be genetically engineered to have useful traits that are not found in wild populations,
Explanation:
Answer:
PROMOTER is a DNA sequence where RNA polymerase binds and begins the process of transcription. ENHANCER is a D N A sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.
Explanation:
The production of egg and sperm cells follows a certain sequence of events.
The correct order of those events are:
MEIOSIS, CELL DIFFERENTIATION, MATURE GAMETES.
Meiosis is defined as the process wherein a single cell is divided twice to produce four cells that contains half the original amount of genetic information.
Cell differentiation is defined as the process wherein the less specialized cell becomes a more specialized cell. The haploid cells are the end result of meiosis. They must undergo cell differentiation before they can become mature gametes.
