Answer:
All phospholipids have hydrophobic tails, consisting of the two hydrocarbon chains, and hydrophilic head groups, consisting of the phosphate group and its polar attachments. Consequently, phospholipids are amphipathic molecules, part water-soluble and part water-insoluble.
5. By about how much did average global temperatures increase from 1880 to
2020?*
A certain species of trilobite is known to have lived 300 million years ago. If this index fossil was found in a rock layer containing other fossils, what could you infer about the other fossils
a The rock layer killed the trilobite and the other fossils
b The other fossils are about 300 million years old
c The organisms that formed the other fossils are still living.
d The rock layer formed before the trilobite and other organisms
Answer:
b The other fossils are about 300 million years old
Explanation:
From the description of the problem given, we can correctly conclude that the other fossils are about 300 million years old and even the rock layers formed around that period in time too.
Fossils are the preserved remains of organisms that has once lived. Through the principle of relative dating we can determine the age of fossils and those of other related ones. According to the principle of fossil and fauna succession, "fossils succeed one another in a predetermined form". So, the fossils occurring together within the rock layers are of the same age.1 Invasive plant species affect the interactions of living and nonliving components
of an ecosystem, so the removal of invasive plants is often necessary. The goal of
most plant-control methods is to disrupt or inhibit the function of different plant
systems. For example, insects can be used to chew through roots in order to
reduce a plant's ability to absorb water.
Which of these functions would be most immediately affected by a reduction in water
uptake by roots?
A Disease resistance
B Seed dispersal
C Sunlight absorption
D Photosynthesis
Answer: photosynthesis
