A joint held together by fibrocartilage would be classified as a __________ joint. a joint held together by fibrocartilage would
sp2606 [1]

Answer:

<u>Cartilagenous joint</u>

Explanation:

A cartilaginous joint where the bones are joined by fibrocartilage is called a symphysis. Fibrocartilage is very strong because it contains numerous bundles of thick collagen fibers, thus giving it a much greater ability to resist pulling and bending forces when compared with hyaline cartilage. This gives symphyses the ability to strongly unite the adjacent bones, but can still allow for limited movement to occur.

Answer:

8. D

9. A

10. A

11. C

12. D

Explanation:

8. Natural selection works on variation that exists in the genes of organisms. Antelopes who have genetic variation that makes their legs more muscular are at an advantage because they can outrun predators. This increases the chance that they will reach reproductive age, and be able to pass this advantageous trait onto their offspring. Over time, this selection pressure makes the variant more common in a population.

9. Beneficial traits are those that give a selective advantage. This could be one that helps it outrun predators (like above), avoid illness and death, gives it a reproductive advantage (i.e. more attractive to mates), or makes it better able to digest certain foods, for example. The formation of cancer cells would be harmful for an organism, reducing its fitness and perhaps leading to death. The inability to reproduce would mean genetic info is not passed on to the next generation, and stopping the production of an essential protein would likely lead to death. However, resistance to a virus would help an organism avoid illness and death, improving fitness.

10. Genotypes are what organisms inherit from their parents, i.e. the genetic information that is passed on. However, the way in which different alleles interact and are expressed is the phenotype. If we take the above example, natural selection is acting on the phenotype of muscular legs. If an antelope had the muscular leg genotype but for some reason it was not being expressed (maybe another gene is interfering with it), then the antelope would not have a selective advantage, and natural selection could not be act on the trait.

11. A trait that better suits an organism to its environment will be selected for by natural selection. This is because that organism is more likely to survive due to the trait, giving it a selective advantage. Therefore, if a mutation arose making the giraffe more adapted to the environment, it would be positively selected for, and through evolution would become more common.

12. This is an example of selective breeding, which has been happening for generations. Farmers spot desirable traits, and cross horses with these traits in an attempt to enhance the trait or to ensure it is passed on to the next generation. This is not natural selection, because farmers are making it happen artificially. It is not cloning or recombinant DNA, which are terms scientists use for actually manipulating the DNA in the lab.

The organism shown is a free-living one that is anchored to the bottom of ponds and streams during the first part of its life cy
luda_lava [24]

The common name of this organism is hydra.

<u>Explanation:</u>

Hydra is a fresh water organism and belongs to the phylum Cnidarian. They have tentacles around their body that enables locomotion as well as protection from prey.  Hydra has the ability of regeneration and the asexual mode of reproduction in hydra is budding.

In the budding process, a small bud develops in the parent body and the bud after maturation gets detached from the parent body and grows into a new individual.  Sexual mode of reproduction is also found in hydra.
