Answer:
Using single-lensed microscopes of his own design and make, Van Leeuwenhoek was the first to observe and to experiment with microbes, which he originally referred to as dierkens, diertgens or diertjes (Dutch for "small animals" [translated into English as animalcules, from Latin animalculum = "tiny animal"]).
Leeuwenhoek named the cells he observed originally as dierkens, which is the Dutch word for small animals, and translated to English as animalcules.
Hope it helps :)
Though I may be wrong :( ...
Have a great day!
Answer:
Predict the possible genotypes and phenotypes percentages for the
offspring produced from the cross below if albinism is recessive in
humans. Albino male x Heterozygous female
aa X Aa = Aa, aa, Aa, aa
Explanation:
From the crossing above, it is right to say that albinism and non-albinism occur in a 50-50 ratio i.e 50% each. The genotype shows that there is 50% homozygous recessive albinism while there is also 50% heterozygous non-albinism. The phenotype reflects that there no dominance of albinism or non-albinism, they both share equal phenotypic characteristics
Answer:
Secretion, in biology, production and release of a useful substance by a gland or cell; also, the substance produced. In addition to the enzymes and hormones that facilitate and regulate complex biochemical processes, body tissues also secrete a variety of substances that provide lubrication and moisture.
