Geotropism allows plants to correctly orient themselves for growth. The roots exhibit positive geotropism and grow towards the earth. The shoot shows negative geotropism by growing away from the earth. Phototropism occurs when plants move towards or away from sunlight.
Cardiac muscle tissues are in the walls of the heart, striated and have involuntary control. Skeletal muscles tissue is in all muscle that are connected to the bones of the skeleton, these are under voluntary control. Smooth muscle tissue are in hollow organs beside the heart and are spindle shaped.
Ecosystem energy flow. Energy's life moves. The energy cycle is based on the flow of energy in an ecosystem through various trophic levels. The cycling energy and nutrients obtained from various external sources maintain our ecosystem.
The responses are A, B, and E. A) Because the sun provides the entire ecosystem with energy, it is a major source of energy. B) because photosynthesis is the process in which plants convert radiant energy from the sun into chemical energy to form sugar-known glucose. E) I believe because, as it moves throughout the ecosystem, the amount of energy at each trophic level decreases.
I hope this helped!!!
The disease must be an X-linked disease (both dominant and recessive are possible), or a recessive trait.
The son will inherit one of his mom's X chromosomes and his dad's Y chromosome. If it is impossible for the son to get it, it certainly is not located on the Y chromosome, which he will get from his dad.
It could be on his dad's X chromosome, either dominant or recessive, and he would have a 0% chance of getting it, since he will not get his dad's X chromosome.
It could also just be a recessive, non sex-linked trait, in which case he could not possibly get it because his mom is not a carrier.
<span>Before the completion of the Human Genome Project, it took few years before the well-known forecasts stated that humans had at least 100,000 genes. But latest Human Genome Project evaluates lowered number to a more timid range of 20,000 to 25,000. It has helped to narrow the range of feasible genes and to separate certain candidates as supplying to particular diseases. Scientists have also re-evaluated past conclusions, such as the idea that genes are self-restrained, detached pieces of DNA with defined character. They now know that some genes that tasks simultaneously can make more than one protein; where in fact the average gene might make three proteins. Also, genes will be visible to grab genetic code from other DNA parts</span>
