Yes in fact they do!! Lol google it, i also am trying to get brainley points
Answer:
Hydrogen Bonds Make Water Sticky
Explanation:
Hydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH3), water (H2O) and hydrogen fluoride gas (HF). In these molecules, the hydrogen atoms do not pull as strongly on the shared electrons as the N, O, or F atoms. Therefore, the molecules are polar; the hydrogen atoms become positively charged and are able to form hydrogen bonds to negative ions or negatively charged parts of other molecules (such as the N, O, and F atoms that become negatively charged in these compounds).
Answer:
4 × 10^0 kg or 4×E0 kg.
Explanation:
Before delving into or solving the Calculation, let us check one or two things about worker bees.
WHAT IS A WORKER BEE?.
Bees generally are social insects living in an organized community and they consist of three castes which include; the drone bees, worker bees, and the queen bees.
The queen bees are the female bees while the drone bees are the male bees.
The WORKER BEES are female bees too, but the only difference between them and the queen bees is that they (worker bees) do not reproduce like the queen bees. They are saddled with the responsibility of looking for food and maintaining the hive temperature.
Now to the question, the mass of a bee= 1 × 10^-4 kg. And there are 4 × 10^4 bees in hive. Therefore, the mass of all the worker bees in the hive together = (1 × 10^-4) × (4×10^4).
==> 4 × 10^0 kg, or 4E0 kg.
Answer:
Predators are an important part of a healthy ecosystem. Predators remove vulnerable prey, such as the old, injured, sick, or very young, leaving more food for the survival and success of healthy prey animals. Also, by controlling the size of prey populations, predators help slow down the spread of disease.
