Answer:
Biodiversity
Explanation:
In the given question, many species of plant species used to grow in the empty lot. The plant species could have provided a home to many animal species. This lot thus formed a small level of the biological ecosystem which is composed of biodiversity.
This lot was changed to a park by the city council which then changed the ecosystem of the area and the main factor that was affected by this change is Biodiversity.
Thus, Biodiversity is correct.
Dolphins eat the equivalent of 4-5% of their body mass each day. The sonar frequency most often used by thedolphins is around 100kHz. Notice thequalitative data are descriptions. Thequantitative data are objective, numerical measurements.
Answer:
- If it were true, all organisms would be complex and simple organisms would disappear
- It does not account for genetic mutations known to affect physical traits
Explanation:
Lamark's theory of evolution is that changes in the organism's physical form during its lifetime can be passed on to its offspring. In other words, he believed that children can inherit acquired characteristics from their parents.
The classic example is that he believed giraffes evolved long necks because they would stretch upwords to eat leaves from tall trees, elongating their necks, and then would pass on a longer neck to its children. Or in humans, that a body builder would make a muscular child because of their intense training!
There are a few problems with this theory:
- If we believe this theory, organisms would always be getting more and more complex and 'improved', so simple organisms would disappear.
- We know that changes to the DNA influence inherited physical characteristics, not simply continued use
Answer:
Which statement correctly describes the nuclear envelope of a eukaryotic cell? The nuclear envelope is a single membrane, consisting of a phospholipid bilayer. Plasmadesmosomes in the nuclear envelope permit the exchange of macromolecules between the nucleus and the cytoplasm.
