In the classification of life, bacteria, archaea and eukaryota are which of the following?
domains |
|
species |
|
classes |
|
kingdoms |
The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.
Examples of primary consumers include:
all of these |
|
fish |
|
cows |
|
rats |
Primary consumers (herbivores) subsist on producers like plants and fungus. Examples are grasshoppers, cows, and plankton.
Within DNA, a variety of a particular gene is called a(n):
heterozygous |
|
homozygous |
|
allele |
|
chromosome |
The gene is the base unit of inheritance and is contained within DNA. A gene may come in several varieties (alleles) and there are a pair of alleles for every gene. If the alleles are alike, a person is homozygous for that gene. If the alleles are different, heterozygous.
In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
sugar |
|
mitochondria |
|
oxygen |
|
water |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
A large naturally occurring community of flora and fauna occupying a major habitat is:
a community |
|
a food chain |
|
a biome |
|
a population |
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
