Anton van Leeuwenhoek is a scientist who saw cells soon after Hooke did. He made use of a microscope containing improved lenses

that could magnify objects almost 30ox. Under these microscopes, Leeuwenhoek found moving objects that he named "animalcules," which included protozoa and other unicellular organisms, like bacteria. He was also able to observe red blood cells and sperm cells. To which of the tenets of the Cell Theory did Leeuwenhoek make the biggest contribution?

Answer: Leeuwenhoek biggest contribution is to the first tenet of the cell theory.

Explanation: the first tenet of cell theory states that every living being is made of cells and even an organism can be made of just one cell able to reproduce by itself.

Leeuwenhoek observations stablish the existence of microscopic structures alive some with movement. This helped other scientists to determinate this structures were cells that can make vital processes such as feeding, breathing or reproducing which are determinant in biological definition of life.

In horses, the allele for a black coat (B) is dominant over the allele for a brown coat (b). A cross between a black horse and a
GaryK [48]

Answer:

Bb X bb

Explanation:

  • It is given that the allele B for the black coat is dominant over allele b for a brown coat.
  • A dominant allele always leads to the expression of the dominant trait in the heterozygous condition. 
  • When a black and brown horse is crossed as given in the question and the result is a brown foal, then the genotype of the brown foal must be bb as the brown coat is a recessive trait. 
  • Since each parent contributes one allele each for a given gene, the black horse must have b allele, and hence must be heterozygous Bb.
  • The cross is shown in the punnett square.
