Answer:
how changes in biodiversity impact an ecosystem
Explanation:
Water hyacinth is a free-floating perennial aquatic plant. This plant is native to tropical and sub-tropical South America. As an invasive species, when it grows in the new environment causes severe ecological or economic harm. By growing where it not native, it can spread extremely fast, blanketing a water surface in a very short period of time. It can limit boat traffic, swimming, and fishing, and it can deprive native plants and animals of sunlight and oxygen, thus reducing the local biodiversity.
This is how an ecosystem effects biodiversity impact. When a biological species grows in the new environment, It can affect the biodiversity or environment that can affect the biological species.
Answer:
Let:
Y = Yellow R = Round
y = green r = Wrinkled
If you look at the F1 generation, all the plants are round and yellow, so these are the dominant traits and each offspring is heterozygous for both traits. The cross for the F2 generation would then be:
<em>YyRr x YyRr</em>
In a Punnett it would look like the attached picture.
For the forked-line diagram, first you will need to know the gentypes and ratio of each trait in a monohybrid cross. Select one trait, and then branch each gentype to the next trait, linking it with each possible genotype combination of the monohybrid cross.
Attached is a picture of the Forked Branch diagram for this cross.
Mainly Osteoarthritis (OA) happens when the joint-associated problems that can occur as normal changes to the articular cartilage as an individual ages.
It is a classic age-related disorder. It is often described as a chronic degenerative disease and thought by many to be an inevitable consequence of growing old. Cartilage is a firm, slippery tissue that enables nearly frictionless joint motion. Eventually, if the cartilage wears down completely, bone will rub on bone. In OA, degradation and loss of the articular cartilage is a central feature that is sometimes attributed to "wear and tear".
Beside Osteoarthritis, fibrillation of the articular surface, decrease in the size and aggregation of proteoglycan aggrecans, increased collagen cross-linking and loss of tensile strength and stiffness happens.
