The gallbladder provides ________ that aid(s) in transport of lipids across the intestinal membrane.
The gall bladder provides bile salt.
The gall bladder is a small pear-shaped organ that is located at the abdomen inferior to the liver.
This organ stores and releases the bile salt produced from the liver.
The bile salt is released through the bile duct into the duodenum of the small intestine.
The bile salt is use to emulsify fat thereby aiding it's transport across the intestinal membrane.
Therefore, the gall bladder provides bile salt that aids in transport of lipids across the intestinal membrane.

How might the interdependence of organisms in a specific habitat be
helped or harmed as a result of changes in the ecosystem over time?
Changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.
What is the effect of change in ecosystem over time on the interdependence of organisms in a specific habitat?Changes that occur in an ecosystem may occur as a result of natural or man-made causes.
Changes in an ecosystem may have positive or negative effects on the interdependence of organisms in a specific habitat.
For example in an aquatic habitat where certain species of fishes like sharks depends on smaller fishes like salmon to survive, if humans were to reduce the salmon population by overfishing, the sharks will be negatively affected as they may have to migrate to new hunting grounds.
However, some other fishes that are prey to shark may be able to grow more with the reduction on shark population in that area.
Therefore, changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.

The sequence by which electrons travel downhill during aerobic respiration. The se sequence has NADH, oxygen chain of transportation of electron, food and NAD.
Respiration (both aerobic and anaerobic) begins with glycolysis in the cytoplasm of a cell;
1 glucose molecule (C₆H₁₂O₆) is converted into 2 molecules of pyruvate in a 10-step process, consuming 2 ATPs and yielding 4 ATPs;
Additionally, 2 NAD+ molecules are reduced to NADH molecules;
In aerobic respiration, each pyruvate molecule then goes through the link reaction, getting converted to acetyl co-A in the mitochondrial matrix, producing 1 CO₂ molecule and 1 reduced NADH molecule;
Acetyl co-A then enter the Krebs or tricarboxylic acid cycle (TCA) where 2 CO₂, 1 ATP, 3 NADH (by reduction of NAD+) and 1 FADH₂ molecules are produced;
The NADH and FADH₂ molecules produced are electron carriers required for the electron transport chain (ETC);
The electron transport chain consists of 4 proteins within the inner mitochondrial membrane which are involved in the production of ATP by oxidative phosphorylation;
The first protein (C1) is responsible for oxidising NADH to NAD+, releasing energy used to generate the proton motive force (PMF) by pumping the protons (H+ ions) into the intermembrane space and the electrons released are transferred to a ubiquinone molecule;
The second protein (C2) is responsible for oxidising FADH₂ to FADH, also releasing energy used to generate the proton motive force (PMF) and, similarly to C1, the electrons released are transferred to ubiquinone;
The third protein complex (C3) transfers the electrons from ubiquinone to cytochrome C;
Finally, cytochrome C transfers these electrons to the fourth complex (C4), where they combine with free protons in the matrix and O₂ to to produce H₂0;
The PMF is then harvested via an ATP synthase protein where H+ flood back into the mitochondrial matrix, and the energy released is used to generate ATP from ADP and Pi;
ATP is now ready for use for bodily processes requiring it.
What can you infer about the position of the galaxies 100 million years
before this telescope photo was taken? How does this relate to the big bang
theory?
Although the picture for this question is not given, if we have the possibility to view galaxies from 100 million years ago and compare them to the photos we have today, we would see that their positions would be different.
Why would the position of the galaxies have changed?This has to do with the fact that the universe is always expanding.
The idea of an expanding universe means that galaxies are moving farther away all the time.
However, due to the effects of gravity, some galaxies pull each other in and form groups or clusters.
Therefore, due to the formation of galaxy groups or clusters, the position of galaxies may have changed in relation to others from outside its groups in the last 100 million years, while remaining the same relative to other galaxies in its local group.

What is a biome?A biome is an ecological unit that depicts the occurrence of a biological community in response to the particular climate and the environment.
Biomes support variety of habitats across the different continents. Various biomes together constitute a biosphere.
A biome is identified on the basis of temperature and precipitation it receives annually. The presence or existence of organisms is dependent on these two factors.
Based on topography, biomes can be classified into terrestrial, fresh water and marine biomes.
Some of the well known examples of biomes include tundra region, taiga region, grasslands, desserts and forests.
There are also special types of biomes known as ecotones where the two biomes merge. Salt marshes are the example of ecotone.
