What does Donor means in coordinate​
Roman55 [17]

Answer:

Donor coordination is meant to counteract this and has become an important item on the international development agenda.The underlying reason for this is the growing pressure to improve the efficiency and effectiveness of development cooperation exerted, on the one hand, by the ambitious Millennium Development Goals (MDGs) and the comprehensive poverty reduction strategies being pursued by many low-income countries and, on the other hand, by scarce development cooperation resources.

Birds and mammals have a four-chambered heart, but most reptiles have a three-chambered heart. How does this fact affect the con
eduard

Answer:

The animals present body structure is due to evolution. It is seen in each part including the structure of the heart. The vertebrate heart becomes complex from a simpler form.  

Invertebrates, the heart of fishes is two-chambered having one auricle and one ventricle. The deoxygenated blood gets purified in the gills. They are aquatic and no lungs for breathing. The hearts pump a mixture of oxygenated and deoxygenated blood to the body.  

The amphibians and reptiles have 3 chambered heart as they lead terrestrial mode of life. The gills modified into the lungs.  The left auricle receives pure blood and the right auricle receives deoxygenated blood. The blood purified in the lungs and in the ventricle, both types of blood get a mix. The ventricle pumps the mixed-blood throughout the body.

In the case of birds and mammal, the heart is 4 chambered and the oxygenated and deoxygenated blood are separated. These two are higher vertebrates. No mix of pure and impure blood, the body receives only the oxygenated blood.

This shows to construct the phylogenetic tree of vertebrates - the fishes should be in the bottom, and above it amphibians, reptiles, then, mammals and birds on the top branch of the tree. As the chambers and structure of the hearts modified one after another.

A widows Peak is dominant over straight hairline the genotypes of The Offspring are WW, Ww, ww and ww. What are the phenotypes o
anastassius [24]

Phenotypes are the physical characteristics that result from the genotype, which is the genetic makeup of the organism. In this case, either straight hairline or Widow's peak will be the phenotype, as they are the physical characteristics being discussed.

The questions states that a Widow's peak is dominant over straight hairline. So we are going to assume that the Widow's peak allele is W (dominant), and the straight hairline allele is w (recessive).

A dominant allele will mask the presence of a recessive allele unless both of the alleles are both recessive (both ww).

So for the WW genotype, we are going to see the dominant phenotype: Widow's peak.

For the Ww genotype, we are also going to see the dominant phenotype since the dominant allele is going to mask the presence of the recessive allele, so we are going to see: Widow's peak.

Lastly, for the ww genotype, we are going to now see the recessive phenotype, since both alleles are recessive: straight hairline. Note that their are two of these type of offspring as stated in the question.
