Answer:
a. eukaryotes
b. unicellular
c. autotrophs; heterotrophs
Explanation:
Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.
Answer:
What Is the Evidence for Evolution? Darwin used multiple lines of evidence to support his theory of evolution by natural selection -- fossil evidence, biogeographical evidence, and anatomical evidence. Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are likely to be evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. ... In humans, the tail is reduced to the tail bone.
Image result for Three lines of evidence that provide support for common ancestry and evolution are Similar embryology, Molecular homologies, and The Fossil Record.
Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.
Water would move out of the cells of the microorganisms by osmosis and the cytoplasm would become dehydrated, killing the cells.
The brine is a hypertonic solution, thereby "pulling" the water out of the bacterial cells.
<span>The genotype is
required for you to use a punnet square. In the construction of a punnet's
square, the genotypes of both parents are required. In the three by three
square, the first column shows the genetic representation of one parent and the
first row shows the genotype of the other parent. The two are combined, and
they yield a genetic combination of both parents, giving all the possible
outcomes of the offspring's genotypes. Using the punnet's square, you can be
able to identify the percentage of the offspring that will be heterozygous or
homozygous.</span>
The brain is a part of the central nervous system together with the spinal chord.
The other part of the nervous system is the peripheral nervous system which is consisted of nerves and ganglions.
Humans own their ability of speech to the three areas in the brain.
Broca's area is essential for forming words, Wernicke's area helps us understand the meaning of words and the arcuate fasciculus connects these two areas and gives speech coherence.
