Answer:
Lack of gravity causes you to use less work to move your muscles.
Explanation:
If on Earth your arm weighs 3 pounds, the muscle will only have to move 3 pounds of force. For example, if you were to go on the moon, your arm would have the same mass but there would be less gravity pulling it dow. So now your muscles only need to pull 1 pound. Over extended periods, you would be working less, thus not using your muscles to fullest potential and in result you would get weaker.
Answer:
A. an increase in genetic diversity
Explanation:
Genetic diversity is the degree of gene variety within a single species (animal or plant). It corresponds to the total number of genetic characteristics in the genetic composition of species or subspecies. Genetic diversity is one of the main aspects of our planet's biodiversity, such as populations and ecosystems.
In the case of Siamese cats, genetic diversity has caused some lineages to change their appearance from classic to modern. This occurred by crossing Siamese cats with cats of other breeds, creating a wide genetic variety that resulted in the change in appearance of these cats.
<h2>Role of Springtalils in Moss Reproduction</h2>
Explanation:
- Bryophytes are the group of seedles plants that are the closest enduring relative of early natural plants
- In light of the fact that they nonappearance of lignin and other safe structures, bryophyte fossil advancement is ridiculous and the fossil record is poor. A couple of spores guaranteed by sporopollenin have persevere through and are credited to early bryophytes. By the Silurian time allotment, in any case, vascular plants had spread through the territories. This persuading truth is used as evidence that non-vascular plants likely went before the Silurian time system
- In a bryophyte, all the conspicuous vegetative organs, including the photosynthetic leaf-like structures, the thallus, stem, and the rhizoid that hooks the plant to its substrate, have a spot with the haploid living thing, or gametophyte. The sporophyte is hardly unmistakable. Right now, gametophyte is the transcendent and most ordinary structure; the sporophyte appears for only a short period. The sporangium, the multicellular sexual regenerative structure, is accessible in bryophytes and missing in the greater part of green development. The sporophyte early living being in like manner stays added to the parent plant, which guarantees and supports it. This is a trait of land plants
