B. It is impossible to say. Fossils are very old, so we cannot make observations of the trilobite’s ancestors, and we cannot explain its body structures.
C. All species have their own specific body structures, so it is a coincidence that this trilobite and blue crab each happen to have the biramous limb structure.
D. The trilobite and blue crab are different species, so they must not share an ancestor population. They inherited their biramous limb structure from separate ancestor populations.
YALL HELP PLS
Answer:
I think the answer is b
Explanation:
b The trilobite and blue crab both share the same ancestor population that had a biramous limb. They inherited this structure from the ancestor population. c All species have their own specific body structures, so it is a coincidence that this trilobite and blue crab each happen to have the biramous limb structure.
A biramous limb is one that divides into two branches, each of which is made up of a series of segments attached end-to-end. Both species have biramous limbs as the trilobite and blue crab are different species, so they must not share an ancestor population. They inherited their biramous limb structure from separate ancestor populations, i.e., option D.
What are ancestors?An ancestor is a parent or the parent of an antecedent, also recognized as a forefather, fore-elder, or forebear.
An ancestor is from whom organism is descended In law, the person who has inherited an estate.
As in the given scenario, fossil trilobite and this living blue crab both have a limb structure called a biramous limb as the trilobite and blue crab are different species, so they must not share an ancestor population.
They inherited their biramous limb structure from separate ancestor populations.

The concentration of potassium in human blood is extremely important for a huge array of functions that are vital to survival, and research has found that individuals whose potassium levels are regularly too high or too low have a higher mortality rate than individuals with normal levels. Given this finding, which feedback mechanism is most likely involved with potassium homeostasis
Answer:
negative feedback
Explanation:
The ability that cells have to adapt to their environmental conditions is fundamental for their survival. In cell biology, negative feedback is considered to be the predominant feedback mechanism. Negative feedback occurs when the increase in the concentration of a particular molecule leads to its subsequent decrease (or the decrease of another molecule), therefore bringing the system to the initial state. Thus, negative feedback leads the output of the system (in this case, the cell) to be lessened in order to stabilize the system (i.e., previous homeostasis or equilibrium of the system). Potassium is the most abundant positive ion (proton) in any type of cell, being fundamental for many diverse cellular processes such as, for example, regulation of the cell volume and protein synthesis. Potassium homeostasis is controlled by a negative feedback loop in which participate proton transport proteins and a bicarbonate buffer system that serves to counteract low external potassium levels.

When the rate of transpiration exceeds the rate of water absorption, the leaves wilt
and droop while the stem remains upright.
Explain why the stem remains upright when the leaves wilt.
Answer:
When the soil of a plant runs too low on available water, the water chains in the xylem become thinner and thinner due to less water. When this happens, the plant loses its turgidity and begins to wilt. Low soil moisture is often the reason this happens but other factors play a role as well.

Plants contain the carbohydrates starch and cellulose. in the spring when stem growth is at its fastest rate, cellulose production rates are
increased in some plants. In the months with less sunlight, the level of starch decreases in some plants. What does this information
demonstrate?
Answer:
The correct answer is - Two functions of carbohydrates are structural support and energy storage.
Explanation:
In plants there are normally two carbohydrates are produced are starch and cellulose that have similar molecular structures but their biological function is drastically different.
Cellulose is used as a structural unit of the plant cell wall, its production rates increase during the growth of the plant during spring. starch is a carbohydrate that stores energy reserve that builds up during a sunny time and is consumed during wintery or less sunny days.

Compare and contrast ocean upwelling and spring and fall turnovers (similarities and differences.
Answer:
Similarity is the circulation of water and the difference is its location where it occurs.
Explanation:
Ocean upwelling is a phenomenon in which dense, cooler, and usually nutrient-rich water from deep water are moved by the wind towards the ocean surface, which replaces the warmer surface water while on the other hand, fall turnover is the time when the water temperature is uniform throughout the water body. Both ocean upwelling and fall turnovers are similar to each other due to circulation of water with the help of wind. Both ocean upwelling and fall turnovers occurs in different location, ocean upwelling occurs on the shore whereas fall turnovers occurs in every part of water body.

which are the three layers of the earth?Our earth is made up of several layers which are furthur divided into the three types: Crust, mental and core.Crust layer is the most uppermost layer of earth which acts like skin of the earth, it divide into the many plates which are smooth and build up pressure.
Mantle is the largest layer located under the sima composed of very dense and hot rocks. This layer under heavy weight pressure flows like asphaults. Thier movement is responsible for the plates of earth movement.
Core consist of very hot metals and all metals present in this layer is present in the form of liquid.outer core is consisted of nickel and iron in liquid from. Inner core is mostly consist of iron and it is solid in nature.
Asthenosphere is the basically the zone of the earth's mantle. it is malleable and keep the earths plate present in crust lubricated.it is present just below. it is present above the mantle and below the crust.Crust acts like the outer skin of the earth.

2. A fruit fly is classified as a consumer rather than as a producer because it is unable to 1. reproduce asexually 2. synthesize its own food 3. release energy stored in organic molecules 4. remove wastes from its body
Answer:
2. synthesize its own food
Explanation:
