In the plasma membrane, the phospholipid heads Group of answer choices are hydrophilic and face inward, shielded from water. are hydrophobic and face outward toward the aqueous solution on both sides of the membrane. are hydrophobic and face inward, shielded from water. are hydrophilic and face outward toward the aqueous solution on both sides of the membrane.
Answer:
are hydrophilic and face outward toward the aqueous solution on both sides of the membrane
Explanation:
The plasma membrane is structurally made up of a phospholipid bilayer, which is amphipathic in natire. This means that the phospholipid layer of the plasma membrane consists of phosphate head that is water loving or hydrophilic in nature and a lipid tail that is water fearing or hydrophobic in nature.
Since the phosphate head is HYDROPHILIC, they face outward toward the aqueous (water) solution on both sides of the membrane. This allows the phosphate head to attract water molecules.

Why are there always more producers than consumers in an ecosystem?
O A. Plants do not carry out enough photosynthesis to supply the needed oxygen to primary consumers.
O B. The Sun cannot supply enough energy to support many predators.
O C. Energy is lost in food chains so many secondary consumers cannot be supported.
OD. Many consumers would contribute too much carbon dioxide to the carbon cycle.
Answer:
energy is lost in the food chains so many secondary consumers cannot be supported

The ozone destroying pollutants primarily comes from air conditioner coolants, refrigerator coolant, aerosol spray, and plastic foam. *
true
false
Answer:
true
Explanation:
Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms.

Highlight all the atoms of the four functional groups, but do not highlight any bonds. When you click on each atom, it will change color. To deselect an atom, click on it again. Before you submit, check that you have not selected any bonds.
Hi. You did not submit any image, table or description of a molecule for the functional groups to be pointed out. This makes it impossible for your question to be answered. However, I will try to help you as best I can.
A functional group is a set of atoms of different chemical elements that take the place of a hydrogen atom that was part of a hydrocarbon (it is a molecule composed of carbon and hydrogen atoms). The most common functional group is −OH, but you also often encounter −SH, −NH2, and −OPO2−3 functional groups.

Changes in global temperature and other Choose... conditions have effects on organisms and on the clades to which they belong. The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of a Choose... pattern. This pattern includes Choose... extinction, which tends not to disturb ecosystems, as well as Choose... extinction, in which ecosystems change drastically.
Answer:
larger macroevolutionary patterns.
extinction, in which ecosystems change drastically
Explanation:
The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of larger macroevolutionary patterns. This larger macroevolutionary patterns occur due to climate change. Extinction of organisms in which ecosystems change drastically that leads to unfavourable environmental conditions which decreases the population to the extinction of organisms.

Luisa went into the bathroom after her sister had a bath. It was full of mist and the mirror was covered with the a lot of liquid drops. What was the mist made of?
Answer:
Mist is made of water vapor.
Explanation:
The bathroom mirror and the fog that the bathroom presents after someone takes a shower, is formed by water vapor. This water vapor is formed by the hot water from showers, which evaporates. This water vapor is what forms the mist, however, when this mist touches the surfaces of the bathroom, such as the mirror, it becomes water again and that smothers the mirror. The mist becomes water when touching the mirror because of the difference in temperature between them, as the mist is hot and the mirror is cold. This happens through the condensation of water.

Molecules on the outer surface of a microorganism act as____
The immunostimulants act as those molecules that are found on the outer surface of the microforms.
What are microsorgams ?The microorganisms are those organisms that can only be seen through the microscope and include the bacteria, the protozoa, the algae, and the fungi.
The virus is not considerd to be living and has a single cell or may form a colony of cells. The unseen microbial life is scripted in the 6th century BC. As these microorganisms have a single-celled life they are more diverse.
The presence of the immunostimulants on the body of the micro organs tells about the outer surface of these microorganisms.
