1. b - plants make their own food (glucose)
2. 1 - fish and upwards have a jaw (there are fish that do not have jaws, but this is likely where the divergence happens - before 1 is likely jawless fish.
3. b - cellular respiration
4. They belong to the same kingdom (Animalia) but different phyla (dogs are in the phylum Chordata - insects are not)
Answer:
The species that will be most similar to humans will be
1. rhesus
2. pigeon
3. fruit fly
Explanation:
Evolution can be described as the process in which different organism evolve from common ancestors over a long period of time. Evolutionary studies show that some organisms have more shared characteristics as compared with other organisms. These organisms with common characteristics are believed to be closer to one another and evolved from the same ancestors.
In the above question, as there is only one difference between the cytochrome c of humans and rhesus, hence rhesus is the closest to humans. Pigeons has lesser number of differences than fruit fly, hence it is second on the list. Fruit fly has the maximum differences hence it is placed last.
Answer:
Chromosome 11 likely contains 1,300 to 1,400 genes that provide instructions for making proteins
Answer:
The genes are linked and 10 mu apart.
Explanation:
A female AaBb rabbit is test crossed with a male rabbit (aabb). The male can only produce<em> ab</em> gametes (all the progeny will have ab on one of the homologous chromosomes).
If the genes assorted independently, the female would produce 4 types of gametes with the same frequency: 1/4 AB, 1/4 Ab, 1/4 aB and 1/4 ab.
However, the observed AB and ab gametes were much more frequent than Ab and aB, which means that the genes are linked and alleles on the same chromosome do not assort independently during meiosis.
Recombination is a rare event, so the most abundant gametes are the parentals. That is how we know that the mother had the AB/ab genotype. The recombinant gametes therefore are Ab and aB.
Distance (mu) = # Recombinants × 100/ Total progeny
Distance = (54 + 46) × 100/ 1000
Distance = 100 × 100/1000
Distance = 10 mu
any differentiate between g
