iron in the outer core aligns with that magnet's magnetic field.
B. Convection currents in the core generate a magnetic field, which is
strengthened by convection currents in the mantle.
C. The crust becomes magnetic because of radiation from the sun,
and the resulting magnetic field makes all of Earth's layers
magnetic
O D. Convection currents in liquid iron in the outer core generate an
electric current, which produces a magnetic field.

U can add more if u like it!Regarding fluid shifts and dehydration, when ADH secretion increases to regulate sodium balance by means of increased water retention without additional water consumption (i.e., you lost water but retained electrolytes and didn't drink water], the end result is:
Answer:
increase Na+ levels in ECF compared to the original condition.
Explanation:
The increase in ADH secretion increases to regulate sodium balance. The will be increase sodium levels in ECF compared to original conditions. The is no additional water consumption in the reaction and electrolytes will be retained.
To test how fertilizer affects tomato plants, a farmer divided a field of young
tomato plants into 10 plots of equal size. The farmer then put fertilizer on half
of the plots and no fertilizer on the other half of the plots. What is the control
group in this experiment?
Answer:
The plots with no fertilizer
Explanation:
In an experiment, the control group is used as a comparison for the experimental group (the group being actively changed and observed).
So, in this experiment, the control group is the plots with no fertilizer.
This acts as a good control group because it provides a normal standard to show the effect of fertilizer on the tomato plants.
So, the control group in this experiment are the plots with no fertilizer.

fungus fruit bat
A. To recycle molecular building blocks
a
B. To break down photons
C. To gather green light
O D. To convert light energy into chemical energy
Answer:
OptionA because decomposers are associated
Explanation:
The role of the fungus in the food web shown is to recycle molecular building blocks. The correct option is A.
What is food web?A food web is a diagram that depicts the interconnection of various organisms in an ecosystem via the exchange of energy and nutrients.
The food web is made up of several interconnected food chains that represent the flow of energy from one organism to the next.
Fungi are decomposers that play an important role in breaking down organic matter and recycling nutrients in many ecosystems.
The fungus in the food web is most likely breaking down dead plant or animal matter, releasing nutrients like carbon, nitrogen, and phosphorus back into the soil.
These nutrients are then absorbed by plants, which are then consumed by herbivores such as the coati and sloth.
Thus, the correct option is A.

In the plasma membrane, the phospholipid heads Group of answer choices are isotonic and do not respond to water. are hydrophobic and face inward, shielded from water. are hydrophilic and face inward, shielded from water. are hydrophilic and face outward toward the aqueous solution on both sides of the membrane. are hydrophobic and face outward toward the aqueous solution on both sides of the membrane.
Answer:
hydrophilic and face outward toward the aqueous solution on both sides of the membrane
Explanation:
The cell membrane is mainly composed of phospholipids, which are arranged in a lipid bilayer. In general, phospholipids consist of a glycerol unit, a phosphate group, and two fatty acids. In a lipid bilayer, hydrophilic (polar) phosphate heads are always oriented outwards and interact with surrounding water molecules; whereas hydrophobic fatty acid tails are oriented towards the center of the lipid bilayer away from water. It is for that reason that phospholipids are considered to be amphipathic molecules, where fatty acids confer hydrophobic properties and polar phosphate groups confer hydrophilic properties.

Which of the following statements explains the importance of carbon in cells? (Choose all that apply)
Carbon affects the function of a cell.
Carbon is a waste product for a cell.
Carbon provides structure for a cell.
Carbon maintains the proper temperature in a cell.
Carbon can easily make bonds with other atoms, allowing biomolecules like DNA and RNA, which are crucial for the development and replication that characterize life, to take on a variety of shapes and functions. Thus, option C is correct.
What is importance of carbon in cells?Carbon is an essential component for all living things. Due to its role in the production of numerous bonds and essential molecules in all living things, carbon is an important chemical.
Due to its unique chemical structure, carbon may combine with numerous other molecules to form a variety of compounds.
Because of its propensity to create stable bonds with other elements, including itself, carbon is the main component of organic molecules.
It makes up roughly 20% of an organism's weight and is necessary for them to survive, develop, and procreate.
Therefore, carbon provides structure for a cell.
