Answer:
Both perform photosynthesis.
Explanation:
Both perform photosynthesis led researchers to propose that Chloroplast evolved from Cyanobacteria.
Chloroplast is a organelle that contain the green pigment called chlorophyii which perform photosynthesis. This is found in both plant cell and algae cell. This trap light energy from sunlight and uses carbondioxide with water to produce sugar.
Cyanobacteria are known to be the ancestor of chloroplast and they are also refer to as blue green algae because they contain chlorophyii which is a photosynthetic pigment. The Cyanobacteria are able to perform photosynthesis because of chlorophyii which trap light energy from sunlight and uses carbondioxide and water to produce energy.
Answer:
Petal color in snapdragon is an example of incomplete dominance and deviates from Mendel's law of dominance.
Skin color in humans exhibits a continuous variation and is regulated by more than one genetic loci.
Explanation:
Two alleles of a gene do not always exhibit the dominant-recessive inheritance as shown by Mendel. The alleles controlling the petal color in Snapdragon exhibit incomplete dominance since the allele "R" is not able to produce enough pigment in heterozygous condition to completely mask the effect of the recessive allele "r" Therefore, the heterozygous genotype "Rr" gives pink color to petals.
Mendel showed that each genetic trait is regulated by one gene and exhibit discontinuous variations. This is not followed by skin color in humans which is a polygenic trait with multiple genes regulating it. Here, a range of phenotype is present which is regulated by the sum total of the dominant alleles of all the genes involved controlling the melanin production.
Answer:
When disasters hit, animals experience the same terrible effects as people: injury, starvation, thirst, displacement, illness and stress. We move fast to protect animals affected by earthquakes, floods, typhoons and other disasters. We provide food, water, medical care, and other emergency assistance to animals in need
