2 answers:

8 0

The Semi-fluid layer moves in circular movements based on the temperature and density of it's particles. When the particles become less dense, the semi-fluid rises. Once it reaches the bottom of the crust, the particles become dense, and go back to the inner core. Once it's at the inner core, the particles temperature heats up again and causes the circular movements to proceed.

The gene theory declares that all organisms contain coded information in DNA which dictates the form and function of organisms.

<h3>What does the gene theory state?</h3>

Gene theory is one of the major principles of biology that explains the inheritance of traits coded by gene from parents to offspring.

This theory further explains that genes are located on chromosomes and consist of DNA, which stores them.

Therefore, the gene theory declares that all organisms contain coded information in DNA which dictates the form and function of organisms.

Ferns have vascular tissue, xylem and pholem, stem, root, leaves, dominant sporophyte. It's sporophyte possess rhizomes and fronds plus sporingia aldo called sori. Ferns are seedless vascular plants.

Gymnosperms includes the conifers, cycad e.t.c. It has its ovules resting on a scale. The ovules later develop into the seed. These seeds are naked as there are not enclosed in the chambers.

Angiosperms have flowers and fruits and show diuble fertilization. This is a huge clade that consists of all flowering plants. Unlike Gymnosperms

They develop enclosed in chambers known as ovaries.

The dwarf male father with normal height is homozygous recessive for achondroplasia. The male of heterozygous for the character because this is autosomal dominant. He is also normal vision reason he is X-NY.

The women is color blind and normal height. The cross is X-NYAa x XnX naa. The father will produced gametes x-NA,X-Na , YA and Ya and the mother only gamete X-na. So the son of this type of couple is X-nYAa which can be color blind and dwarf and normal height.
