Answer:
Sheep and goats are important livestock species in developing countries. Of the world's 1,614million sheep and 475 million goats, 65% and 95%, respectively, are located in developing countries. Fifty-three percent of the total small-ruminant population in the developing countries is found in Asia, particularly in India and Pakistan, 33% in Africa, and 14% in Latin America (FAO, 1984).
Goats are hardy and well-adapted to harsh climates. Due to their grazing habits and physiological characteristics, they are able to browse on plants that would normally not be eaten by other livestock species. Thus, the presence of goats in mixed species grazing systems can lead to a more efficient use of the natural resource base and add flexibility to the management of livestock. This last characteristic is especially desirable in fragile environments.
Sheep and goats contribute to a broad range of production systems. The most common system throughout the developing countries involve either the extensive system with large herds and/or flocks grazing on arid and semi-arid rangelands or the intensive system with smaller herds and/or flocks kept in confinement, mostly in the humid tropics.
Answer: 4
Explanation:
The pairing of the third (3') base of the mRNA codon and the first (5') base of the tRNA anticodon are less constrained by base stacking.
The phenotype of antenna in crawfish depends on the protein amount in the antenna length. The offspring have different phenotype than their parent because of the amount of protein translated from each parent gene is determining in this.
The gene determines the amount of protein to be present in the antenna to determine its length.
Explanation:
Data given:
Two crawfish parent = medium length antennae, genotyoe Ll
One offspring = short antenna, genotype ll
one offspring = long antennae, genotype LL
The traits in offspring is shown as:
L l
L LL Ll
l Ll ll
The proportion of allele present in the gene determined the length of the antenna in crawfish.
The difference in length of the antenna in crawfish is due to the amount of protein for the phenotype present in the individual. The amount of protein to be expressed in the crawfish is given by both the parents. The tendency of protein expresed define the phenotype of antenna length.
The right answer is "<span>fat soluble are stored in the liver and fatty tissue ...".
Lipids are essentially stored as fatty acids in the cytoplasm of adipocytes. All of these cells form adipose tissue, commonly called "fat".These reserves are much larger in quantity than the reserves in the form of glycogen, in the human body.
"<span>water-soluble vitamins can build to toxic levels ..." is false, hydrosoluble vitamins are rarely toxic, even at high concentrations, and even if they are toxic (which is very rare) is it not due to their circulation in the bloodstream, it is due to their accumulation in cells.</span>

Answer:
c. Retrograde motion of the planets as they moved across the sky.
Explanation:
Ancient Greek philosophers were extremely intelligent people who propounded some ideas that have helped shape science to what it is today.
They had evidence for the spherical shape of the earth, the link between lunar phases and oceanic tides, and the existence of exoplanets, however, they did not have evidence for the retrograde motion of the planets as they moved across the sky because they believed that if the Earth moved around the Sun, then they would be able to see the stars from divergent points along Earth's orbit.
