Answer:
Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. Duplication of the genetic information occurs by the use of one DNA strand as a template for formation of a complementary strand.
Explanation:
Answer:
Linkage
Explanation:
Two genes that occur on the same chromosome are said to be linked, and those that occur very close together are tightly linked.
Answer:
Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made. True
Explanation:
A scientific model can be described as a representation of any scientific topic. The representation may be in the form of a computer simulation, 3 D model, a mathematical equation etc.
The scientific models depict the latest knowledge about a certain topic. With time, as new discoveries are made, the previous scientific theories might be eradicated and new ones might be formed. This will limit the effectiveness of the previous models and new models will have to be made.
(A) sporophyte, pollen cone, microsporangia, microspores, pollen nuclei
What are the various structures of male pine trees?
Like other living things, trees use a number of reproduction techniques. The pine cone, a unique structure that pine trees have evolved, serves as the primary method of reproduction. The pine cone is essential for effective seed fertilization and aids in the spread of seeds over a large area. Typically, a single pine tree will have both male and female pine cones. Pine trees possess both male and female reproductive structures, or cones. Pine trees produce seeds to reproduce. Cones, the male and female reproductive organs of pine trees, are both present. the pollen-producing male cones.
Therefore sporophyte is the largest structure on male pine tree followed by pollen cone followed by microsporangia, microspores, pollen nuclei.
