What are vestigial structures?Vestigial structures are structures that have no apparent purpose and appear to be leftover components from a previous progenitor. The human appendix, a snake's pelvic bone, bone structure to that of modern-day reptiles and the wings of flightless birds are all examples of vestigial features.

If you have 50 mg of starch, how much water needs to be added to make a concentration of 5g/mL.
1:5 dilution = 1/5 dilution = 1 part sample and 4 parts diluent in a total of 5 parts. If you need 10 ml, final volume, then you need 1/5 of 10 ml = 2 ml sample. To bring this 2 ml sample up to a total volume of 10 ml, you must add 10 ml - 2 ml = 8 ml diluent.

A:they are carbon sources in the geosphere
B:they are carbon reservoirs in the geosphere
C:they are carbon sources in biosphere
D:they are carbon reservoirs in the hydrosphere
Answer:The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean's surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths.

Why are proteins NOT a primary source of energy in living organisms (carbohydrates are
primary, lipids are energy storage...)?
Answer: Energy Production
The primary role of carbohydrates is to supply energy to all cells in the body. Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Some cells, such as red blood cells, are only able to produce cellular energy from glucose.

Igneous rock.
(a )Tilting,
(B) Erosion,
(c) Folding
Answer:
B. Erosion
Explanation:
Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.
Erosion is the process of wind, water, and ice breaking down rocks tint smaller pieces. Erosion breaks down igneous rocks, metamorphic rocks and sedimentary rocks. Erosion breaks down igneous rocks in the same manner as it breaks down other rocks

Explanation:
What type of cells have a high concentration of mitochondria?
1) skin cells
2) blood cells
3) heart cells
4) nerve cells
Explanation:
Mitochondria produce cellular energy via respiration, and cells have more mitochondria if they require more energy. So the cell that has the most Mitochondria per cell is easily cells located in the heart. The reason for this is the cell has to continuously pump blood and maintain a circulatory equilibrium, to serve this function it requires energy continuously but it’s good that respiration happens continuously, all the time, 24/7 to keep you alive. Other cells that require more Mitochondria to serve a particular function: the other cardiovascular cells that aren’t located in the heart but in the arteries and veins, the lung cells exporting carbon dioxide from the body and intaking oxygen all the time (fun fact: your lungs are made up of 80% water :) to assist in “filling” oxygen to the blood) another notable place is the hippocampus located in the central part of the brain, this part of the brain maintains CO2 and Oxygen levels in the blood as well as identifying the body’s internal temperature all the time. The pattern, that cells that require to monitor or deliver a particular function continuously require more Mitochondria to assist in the function. So all in all:
The cells of the heartOther cardiovascular cells particularly in the arteriesThe lung cellsThe hippocampusWhen it comes to cells with high concentrations of mitochondria, 3. Heart cells are ranked quite high on the list.
The Mitochondria is very important because:
It is where cellular respiration takes place Produces energy for the cellMuscle cells like the heart need a lot of energy to carry out their functions. The heart for instance needs a higher amount of energy to continually pump blood. For this reason, it has a high concentration of mitochondria to produce that needed energy.
In conclusion, heart cells have a high concentration of mitochondria.

Carbon dioxide is used by plankton during photosynthesis to make organic molecules containing ( lead / carbon / argon / chlorine )
Answer:
Carbon
Explanation:
Photosynthesis is a process carried out by the cells of autotrophic organisms in order to synthesize their own food in form of sugars (glucose). As rightly stated in this question, Carbon dioxide (CO2) is a major ingredient for this process to occur. Inorganic CO2 enters an organism like plankton and is used to make organic molecules.
The organic molecules produced via the photosynthetic process are in form of sugar (glucose) i.e. C6H12O6 whose principal elemental component is CARBON. In other words, the organic molecules contain carbon in their structure, got from the CO2 source.
There are two forms of diabetes. Type II diabetes is also known as late-onset diabetes because it typically affects adults. Consider the following information about Type II diabetes:
Studies have shown that the lifetime risk for developing Type II diabetes is 40% for individuals who have one parent with Type II diabetes.
If a person has two parents with Type II diabetes their risk rises to 70%
Other factors that affect your risk for Type II diabetes include obesity, a sedentary lifestyle (not moving around much), a small or large birth weight, and stress.
Use the information above to answer the question: Is your risk of having Type II diabetes due to your genes, or due to the influence of the environment on your genes (epigenetics), or both?
Answer:
Both
Explanation:
As explained in the passage wether your mom or dad or both have had type ll diabetes in the past determines your risk of having it as well which is part of your genes. But also the influence of the environment on your gene is also a cause to type ll diabetes . Some people would rather stay inside rather than get exercise or some people would rather eat candy or sweets for breakfast or dinner all these things are causes of type ll diabetes which they are caused by the influence big the environment on your genes.
Nemo, a marine fish (adapted for life in the sea salt water ) is placed inside a freshwater aquarium. The next day, the owner finds that he has perished(died) in the tank! Why?
Answer:
The freshwater is hypotonic to the fish
Explanation:
A marine fish is adapted to living in water that is salty.
The fish will not survive because the freshwater would be hypotonic to the body of the fish and as such, excess water would enter its body which will lead to its death. The cells that make up the body of the fish will take-in excess water and lyse, leading to the death of the fish itself.

A. photosynthesis and cellular respiration both use carbon dioxide to release oxygen
B.photosynthesis and cellular respiration both use oxygen and release carbon dioxide
C.cellular respiration uses oxygen and releases carbon dioxide,while photosynthesis uses carbon dioxide and releases oxygen
D. cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses carbon dioxide and releases oxygen
With explanation please and thank you!
Answer:
Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen.
Explanation:
Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen. The correct option is C.
What is cellular respiration?Cellular respiration is a sequence of chemical processes that decompose glucose to start producing ATP, which can then be used as energy to power a wide range of processes throughout the body.
Cellular respiration consists of three major steps namely glycolysis, the citric acid cycle, and oxidative phosphorylation.
The use of photoautotrophic procedures to obtain the glucose required for cellular respiration is an illustration of cellular respiration in plants.
This means that plants can use light energy from the sun to produce glucose and oxygen.
On the other hand, the process of photosynthesis utilizes carbon dioxide and release oxygen as a byproduct.
Thus, the correct option is C.
