Answer:
The chronological order of events ealiest to most recent (1-6) are given below:
Explanation:
1. Hans and Zacharias Janssen created the first microscope in the year 1590.
2. Robert Hooke was the first to use the word "cell." In the year 1665
3. Anton van Leeuwenhoek observed small organisms he called "animalcules." In the year 1674
4. Matthias Schleiden theorized that plants are made of cells in the year 1838
5. Theodor Schwann theorized that animals are made of cells in the year 1839
6. Rudolf Virchow theorized that cells come from other pre-existing cells in the year 1855
The correct answer is :
Some substances but not other can cross the (blank ) membrane of a cell. The blank is to be filled with either cell or plasma. Cell membrane or plasma membrane is the living boundary of a cell which is made of phospholipid. It is a semi-permeable or differentially permeable membrane. It only allows small and non-polar molecules to pass through it. It prevents polar ions or molecules to pass through it
A woman that is heterozygous for neurofibromatosis and a normal man (homozygous recessive for neurofibromatosis) will exhibit a 1:1 phenotype ratio in offspring (Option d).
<h3>What is a rare dominant autosomal genetic disease?</h3>
A rare dominant autosomal genetic disease is a condition inherited in a dominant pattern in very low frequency in the population.
Dominant autosomal genetic diseases are expressed in a 1:1 ratio because they are localized in autosomal (somatic) chromosomes instead of X and Y chromosomes.
In conclusion, a woman that is heterozygous for neurofibromatosis and a normal man (homozygous recessive for neurofibromatosis) will exhibit a 1:1 phenotype ratio in offspring (Option d).
