Answer
The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals. The skeletal system is also called the musculoskeletal system.
Explanation:
Answer:
I think humans and whales are closely related on the evolutionary tree because they are both mammals and both have endoskeleton
The answer is;
- The recombination frequency is proportional to the distance between the two genes
- The lower the recombination frequency, the farther apart two genes are on the chromosome
Genes that are close together are more likely to be passed together to offspring during recombination. Geneticist compares the ration between the proposed phenotype offspring and actual phenotype offerings in a population. The higher the recombination frequency (centimorgans," or cM), the closer the genes are linked together, physically.
Answer:
Natural selection.
Explanation:
Natural selection is when organisms who are most adapted to their environment survive and pass on their genes while those with "unfit" genes die and don't get the chance to reproduce! This slowly creates a population that is most well suited to their habitat. Hope this helps again LOL! :)
Answer: For flowering plants, fertilization occurs through a process known as double fertilization. Unlike most plants, double fertilization enables the new seed to grow into a new plant and have a food source to begin growing. Double fertilization occurs within the female part of a plant, the pistol.
explanation: When pollen is formed by the anther, or male part of a plant, it will blow in the wind or attach to an organism that carries it to the top of the pistol, known as the stigma. Once the pollen attaches to the stigma, the pollen germinates and forms a pollen tube that extends into the ovary. Once formed, two sperm cells will be released and fertilize both the egg and the two polar nuclei of the plant to form the zygote and endosperm, respectfully.
