Cats are smaller animals than humans. Which would you expect to have a (relatively speaking) more active thyroid glan
Answer:
A final conclusion is not possible from this information
Explanation:
In mammals, the thyroid is an endocrine gland composed of two lobes that are connected by a bridge of tissue referred to as thyroid isthmus. The thyroid gland produces different types of hormones including calcitonin, triiodothyronine and thyroxine. These hormones are known to increase basal metabolism and thus affect metabolic-associated mechanisms including appetite, nutrient absorption and gut motility. However, thyroid hormones are not directly associated with the growth rate. It is important to note that the growth hormones are synthesized by the pituitary gland.

Why do higher trophic levels in most ecosystems
contain fewer organisms than lower trophic
levels?
A. Energy available for use to the highest trophic
level is small
B. Energy available for use to the lowest trophic
level is small.
C. Energy available for use to the highest trophic
level is large.
D. Energy available for use to the highest and
lowest trophic levels is the same.
Answer:
A.Energy available for use to the highest trophic level is small
Explanation:
As you go up in the trophic levels, only about 10% of the energy gets transferred from one level to the next. For example, the plants can only harvest 1% of the Sun's energy. The primary consumer can only absorb 10% of the energy from the plant he eats, so .1% of the total energy. The secondary consumer can only absorb 10% of the energy he get from eating the primary consumer, so .01%, and so on and so forth. As we climb up the trophic levels, there is less energy available and therefore less organisms.
Answer:
A. Energy available to use in highest trophic level is small
Explanation:
A is the correct answer because in trophic levels, 10% of the energy from the prior level is transferred to the proceeding level.
So for example, 100% of a plant's energy is transferred to its consumer, the consumer can only use 10% of the original amount of energy.
Then the second level consumer can only use 1% of the original amount of energy.
Then, the tertiary consumer can only use .1% of the original amount of energy.
This makes being a higher level consumer less energy efficient than being a lower level consumer, resulting in fewer higher trophic levels.

The maintenance of normal volume and composition of extracellular and intracellular fluids is vital to life. List and briefly describe the kinds of homeostasis involved.
Answer:
Fluid Balance, Electrolyte Balance, Acid-Base Balance
Explanation:
The amount of fluids and the quantity of each are vital to the body for it to function properly. This is regulated by three kinds of homeostasis.
1- Fluid Balance : The balance of total liquids between the inside of the body and the outside environment so that the cells don't die.
2- Electrolyte Balance : The amount of electrolytes in the body must be kept at a level where the body's at a healthy pH level so that the nervous system and other functions that rely on neurological paths can continue.
3- Acid-Base Balance : It is required to be at a certain point so that the blood does not harm the kidney's and lungs and they can function properly.

Imagine you are working in a real lab setting and when you test the catalase and water together you see a reaction. What does this tell you?(select all that apply) - catalase is not specific to hydrogen peroxide -posible contaminant in the water causing a reaction -catalase is the negative control -you must complete the experiment again to verify your results
Answer:
-possible contaminant in the water causing a reaction
-you must complete the experiment again to verify your results
Explanation:
The enzyme catalase is present in all living organisms and it functions in the breakdown of the hydrogen peroxide into water (H2O) and oxygen gas (O2).
Catalase is specific to hydrogen peroxide. Catalase and water reaction is seen in the lab test because there is the possibility of water contamination and maybe the reaction is not correctly evaluated, so one must complete the experiment again to verify the result.
Hence, the correct options are 2nd and 4th option.
If you are working in a real lab setting and you found out that testing the catalase using water produced a reaction, it is highly likely that the water is contaminated.
Catalase is an enzyme that is substrate specific and its substrate is hydrogen peroxide. The enzyme breaks down hydrogen peroxide to produce water and oxygen. The latter is often seen as bubbles in reactions and the equation is as follows:
[tex]2H_2O_2 ---> 2H_2O + O_2[/tex]
Ordinarily, catalase will not produce any reaction with water. However, if the water contains a slight amount of hydrogen peroxide, such water might be seen as causing a reaction with catalase.

A hydra is an aquatic organism that lives in fresh water. During reproduction an outgrowth begins to form on the parent. The outgrowth continues to develop into the daughter organism and eventually breaks off of the parent. Which type of reproduction does this represent?
Answer:
grow or regenerate into separate individuals. Lizards cast off their tails to escape predators & then regenerate them . ... Hydra reproduces by budding using the regenerative cells. A bud develops as an outgrowth in Hydra due to repeated cell division at one specific site.
Budding is the asexual mode of reproduction. In budding, a genetically identical new organism grows attached to the body of parent Hydra and separates later on. In the process of budding, a bud develops as an outgrowth due to repeated cell division at one specific site .
One popular evolutionary model for the origin of flight in vertebrates is that flight evolved in:_______.
Answer:
skydiving behavior
Explanation:
The flight is an amazing adaptation that consists in the use of aerodynamic forces by flapping the wings. In vertebrates, flight evolved in three independent events: in pterosaurs (i.e., prehistoric winged reptiles), birds, and bats (mammals). In tetrapods, i.e., vertebrates with four legs, it is believed flight had a gliding origin, thereby this feature would have emerged as a consequence of the skydiving behavior necessary to steer the descent.

Pillbugs are placed in a container where they have a choice of a wet or a dry environment. Researchers record how much time was spent on each side
Answer:
This question is incomplete; the complete question is:
Pillbugs are placed in a container where they have a choice of a wet or a dry environment. Researchers record how much time was spent on each side. What is the INDEPENDENT variable?
The answer is the DRY OR WET ENVIRONMENT
Explanation:
Independent variable in a scientific experiment refers to the variable that the experimenter manipulates or changes in order to effect an outcome in another variable called the dependent variable.
In this experiment, researchers are conducting an experiment with pillbugs, which they place in a wet or dry environment to see how much time is spent by the pillbugs on each side. The independent variable in this case is the DRY OR WET ENVIRONMENT which the pillbugs were placed because it is the variable that the researchers could change or manipulate in order to bring out an outcome in the amount of time spent (dependent variable).
Which three elements are often found in organic compounds?
Carbon, hydrogen, and oxygen are the three major elements found in organic compounds. Apart from that, nitrogen, phosphorus, etc. are also seen in organic molecules or compounds.
What is an organic molecule?Organic molecule examples are carbohydrates, proteins, lipids, etc. that are found in the bodies of living animals and plants. Carbohydrate molecules, such as glucose, are composed entirely of carbon, hydrogen, and oxygen, whereas proteins are composed entirely of amino acids. Each amino acid is made up of carbon, hydrogen, oxygen, and nitrogen, and a lipid is entirely made up of only carbon and hydrogen.
In organic molecules, these three remain in high proportion, as a result of which they can be easily broken down by the enzymes in our body or by decomposers after death. All three of these enter the atmosphere via the carbon cycle, for example.
Hence Carbon, hydrogen, and oxygen are the three major elements found in organic compounds.

Would meteorology be a useful science to apply to the study of Mercury the innermost and smallest planet.. Explain !
Answer:
Yes, meteorology could be useful when studying other planets such as Mercury and Mars; atmospheric science has been extended to the field of planetary science and the study of the atmospheres of the planets of the solar system.
It would be ineffective since these two planets have extremely thin atmospheres. They experience very few meteorological processes.
What are meteorological processes?Weather or modifications in the Earth's atmosphere are examples of meteorological phenomena.
If you want to be a meteorologist a weather expert one should pursue a meteorological career. Fog, downpours, tornadoes, and hurricanes are examples of meteorological events.
Meteorology is essential because air quality has an impact on life. First and foremost, weather prediction is critical in urban management.
Cities are preparing for severe weather events such as tornadoes and snowstorms in order to avoid disasters. Second, agriculture relies on long-term weather forecasting.
Thus, as these celestial bodies have extremely thin atmospheres, it would be ineffective. They are subjected to very few meteorological processes.

O 35/36 km
Answer:
Length, [tex]L=\dfrac{7}{5}\ km[/tex]
Explanation:
Given that,
Width of rectangular strip is 5/6 km
Area of rectangular strip is 7/6 km²
We need to find the length of the rectangular strip. The area of a rectangular shaped object is given by :
A = L × B
Putting the values of A and B, we get :
[tex]L=\dfrac{A}{B}[/tex]
So,
[tex]L=\dfrac{\dfrac{7}{6}}{\dfrac{5}{6}}\\\\L=\dfrac{7}{6}\times \dfrac{6}{5}\\\\L=\dfrac{7}{5}\ km[/tex]
So, the length of the rectangular strip is [tex]\dfrac{7}{5}\ km[/tex].
Which condition occurs in the presence of cellular damage? Cells shrink. ATP production increases. Osmotic pressure decreases. Sodium and water move into the cell.
Answer:
Sodium and water move into the cell
Explanation:
Sodium and water move into the cell. This is because
Cellular damage result in failure of the Na+/k+ pump, allowing movement of sodium ions into the cell. This concentration of sodium pulls water in, resulting in hydropic swelling. Cellular damage results in the cell's inability to perform normal metabolic functions because APT decreases and Osmotic finally pressure increases.
