Fungi are __________, whereas plants are autotrophs.
A) autotrophs
B) heterotrophs
Answer: Heterotrophs cannot make their own food, so they must eat or absorb it. For this reason, heterotrophs are also known as consumers. Consumers include all animals and fungi and many protists and bacteria. They may consume autotrophs or other heterotrophs or organic molecules from other organisms.
The electrons in the outermost shell of the covalent compounds are shared by nearby atoms. As there are no free electrons for conducting electricity, the covalent compounds are perfect insulators at absolute zero. As the temperature increases, some electrons move from valence band to conduction band. This gives rise to conductivity. But as the numbers of charge carriers are very low, covalent compounds are poor conductors. On the other hand metals are good conductors cause of their bonding. Metallic bonding consists of a sea of electrons rather than discreet bonds. The free electrons are able to move freely. Since electricity and heat need electrons to move, the bonding promotes conductivity.
Answer:
Differential reproduction leads to a change in allele frequencies over time. This occurs because of natural selection favoring "successful" individuals that produce more viable offspring.
The sickle-cell allele is maintained in populations exposed to malaria through balancing selection, since heterozygous individuals have protection against the disease.
Answer:
The correct answer is option c. "multimale/multifemale".
Explanation:
One of the most common primate groups that could be found in nature are multimale/multifemale groups. This kind of primate grouping is seen more often when predation pressure is high. Only male or only females groups join forces to chase and attack predators more easily that diverse groups, therefore these groups are primate defense system against predators.
The answer is "Interruption of blood flow for even a few seconds impairs brain function. "
When blood fails to circulate in your brain, there is a tendency that you will be suffering from Brain Ischemia. Brain Ischemia can affect your sight, speaking and body movements.
