Answer:
According to the science magazine Scientific American, the sunset is reddish because, when the sun is setting, the light that reaches you has had to go through lots more atmosphere than when the sun is overhead, hence the only colour light that is not scattered away is the long wavelength light, the red.
Answer:
Sexual repro means combining genetics from parents, while asexual repro produces an offspring from only one parent.
Answer: Sally
If Harry's negligent act injures Sally, and Susan, while attempting to come to Sally's aid breaks her arm in the process then, Harry is liable for the harm to Sally.
Explanation:
As a mathematical expression, we can say the action of Harry H, is directly proportional to the injury to Sally S; while the mistake of Susan N is directly proportional to injury to Sally S.
So, if H = S and N = S, it is safe to say
H = N = S.
Thus, Harry negligence create room for Susan mistake, which eventually harmed Sally.
Pioneer species are hardy species which are the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological successions that ultimately leads to a more biodiverse steady-state ecosystem.
1. Bees pollinate flowers and flowers provide nectar for the bees. "M"
2. A tapeworm attaches to the intestines of animals and absorbs their nutrients. "P"
3.Tiny birds helping to keep a crocodile's mouth clean by eating scraps of
food caught between the crocodile's teeth. "M"
4. A tree frog using a plant for shelter from the rain. "C"
5. A tick feeding on the blood of a deer. "P"
Explanation:
Mutualism : If 2 or more species are having an association and the relation is useful to both the organisms in relation, is termed 'mutualism'.
eg: In pollination bees transfer pollens and help reproduce flowering plants and bees get nutrition from the nector.
The plover bird comes to crocodile's mouth as it gives invitation to it to cleanse its mouth and food stuck between the teeth because crocodile cannot go flossing. In turn plover birds gets its food. In this relation both bird and crocodile benefited.
Commensalism: This is a relation between two organisms or species in which one partner is benefited while other neither gets harmed nor benefited.
eg :A tree frog utilizes the shade of plants and hide in the plant to get saved from prey in turn plant does not get anything.
Parasitism: In this association parasite lives in the organism and benefits from it but host gets harmed with this association.
eg: The tapeworm living in intestine of animals attaches to draw nutrition in turn animal gets disease caused by it.
Tick receive nutrition and the deer gets the disease.
