Crickets "chirp" by rubbing their wings or legs over each other. This phenomenon is known as stridulation. It is a means by which male crickets "call" to females to communicate their interest in mating. Frequency refers to the number of chirps that crickets produce during a period of time. Some have suggested that you can tell the temperature and the humidity based on how fast crickets chirp.
Required:
a. What is the effect of temperature on the frequency of cricket chirping? As the temperature rises, the cricket chirp occurs more rapidly therefore increasing.
b. What is the effect of humidity on the frequency of cricket chirping? As the humidity rises, the cricket chirp frequency occurs more rapidly therefore increasing.
Answer:
a. As the temperature rises, the cricket chirp occurs more rapidly therefore increasing. It is correct.
b. As the humidity rises, the cricket chirp frequency occurs more rapidly therefore increasing. It is incorrect. The increase in humidity does not affect the chirp frequency in crickets.
Explanation:
As temperature increases, the frequency of cricket chirp increases too. After listening to the audios, we can see that in the first audio, where the temperature is 14° Celcius, the frequency is 24 chirps in 15 seconds. In the second audio, with 19° Celcius, the frequency is 28 chirps in 15 seconds. In the last audio, where the temperature is 24° Celcius, the chirp's frequency is 34 chirps in 15 seconds. In conclusion, if the temperature increases, the chirps' frequency increases too.
As humidity increases, the frequency of the chirp does not. In the three audios, the number of chirps in 15 seconds was 20. We can conclude that humidity does not affect the frequency of chirps frequency.

List in order the various fluid compartments that a glucose molecule would encounter beginning with absorption from the lumen of the intestine and ending with the glucose molecule entering a skeletal muscle cell.
Answer:
The correct list of compartments glucose enter is :
The lumen > plasma (extracellular fluid) > interstitial fluid (extracellular fluid) > the skeletal muscle cell (intracellular fluid)
Explanation:
The glucose molecule would start from the lumen of the intestine where is absorbed. The glucose enters the plasma a part of the circulatory system known as extracellular fluid.
The glucose also encounters another type of extracellular fluid the interstitial fluid that is not in the circulatory system. At the last glucose as it is entering the skeletal muscle cell the last fluid compartment, which is intracellular fluid. This fluid is inside the cells.
Skeletal muscles are the elongated and elastic cells and fibers also known as the sarcolemma that have numerous nuclei in the periphery of their cells. They are majorly found in the diaphragm, throat, eyes etc.
The correct order of the compartments in which the glucose enters is lumen, plasma (extracellular fluid), interstitial fluid and the skeletal muscle cell.
How does the glucose flow from the digestive system to the muscles?Glucose is derived from the food and the nutrient molecule an organism intakes that reaches the lumen present in the intestine of the digestive system.In the lumen, the glucose molecules get absorbed and then enters the plasma that is the part of the circulatory system, which is also an extracellular fluid.In the plasma, the glucose also encounters the other extracellular fluids and then enters the skeletal muscle cells for providing energy which is the last fluid compartment and are intracellular fluid.Thus, the glucose enters the lumen, plasma, interstitial fluid and skeletal muscle cells.

Fats and oils are rich in nonpolar covalent bonds, specifically C-C bonds and C-H bonds. What is the consequence?
Answer:
they become insoluble in water.
Explanation:
The many C-C and C-H bonds make fats nonpolar and insoluble in water.
The consequence is they become insoluble in water. The correct option is D.
What are fats and oils?One of the three macronutrients is fat and oil (the other two are protein and carbohydrates).
However, fats and oils differ from one another in that fats are primarily derived from animal sources, whilst oils are primarily derived from plant sources.
Because fatty acids are amphipathic, they have polar and nonpolar ends on opposite sides of their molecular structure.
Fat molecules known as monounsaturated fats have only one unsaturated carbon link (also called a double bond). Similar to olive oil, oils containing these fat molecules are liquid at room temperature and start to solidify when it becomes cold.
Therefore, the correct option is D. they become insoluble in water.

Which sphere, regarding carbon would be most immediately affected by a decrease in sunlight?
A Atmosphere
OB. Biosphere
O C. Geosphere
Answer:
A. Atmosphere
Explanation:
Atmosphere would be most immediately affected by a decrease in sunlight because sunlight is responsible for the photosynthesis in plants. if sunlight decreases, the photosynthesis reaction is also decreases in plants and less carbondioxide gas is used by the plant from atmosphere for making their food so we can say that atmosphere is greatly affected by the decrease in sunlight.

the failure of homologous chromosomes to separate correctly during meiosis is called
Answer:
Aneuploidy is caused by nondisjunction
Explanation:
Aneuploidy is caused by nondisjunction, which occurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis. The loss of a single chromosome from a diploid genome is called monosomy (2n-1), while the gain of one chromosome is called trisomy (2n+1).

How can natural selection account for the long tongues of butterflies?
Why are most genes inhibited in an average animal cell
Answer:
Most genes must be turned off because cells play specific functions, thereby only a limited number of genes must be expressed in each cell type in order to produce proteins required in the cell
Explanation:
Gener regulation is a critical molecular mechanism required for normal cell functioning. In consequence, genes are turned on and off depending on the cell type. For example, in the brain, cells that will be differentiated into neurons will be expressed, while genes involved in the differentiation of undifferentiated myoblasts into muscle cells will be turned off. Thus, genes are switched off in order to produce only those specific proteins which are required for each cell during specific developmental programs and functions carried out by each cell type.
The least numerous but the largest of the papillae are arranged as a V-shape on the posterior dorsal surface of the tongue. They contain the majority of taste buds and are called ________ papillae. The least numerous but the largest of the papillae are arranged as a V-shape on the posterior dorsal surface of the tongue. They contain the majority of taste buds and are called ________ papillae. papiform filiform fungiform vallate foliate
Answer:
The least numerous but the largest of the papillae are arranged as a V-shape on the posterior dorsal surface of the tongue. They contain the majority of taste buds and are called vallate papillae.
Explanation:
The shape, location and function of these taste buds make vallate papillae unique. First, they have a distinctive "v" shape, and most adults only have seven to twelve of these papillae, vallate papillae are the least numerous papillae, they are the recipients of the bitter taste. The vallate papillae are the largest and the most specialized, they are located on the back of the tongue, forming the lingual V, in a variable number from 7 to 12. The number of taste buds depends on age, presenting around 270 in the newborn and descending approximately one hundred in individuals older than 75 years. These buttons are located in the crypts or grooves that form the papillae, mainly on their internal face (the annular groove is observed between the papilla and the edge of the calyx), in whose edges the extremities of the taste corpuscles stand out in the form of filaments. Each taste corpuscle comprises two classes of cells: supportive and taste cells.
The largest but least numerous papillae in the dorsal surface of the tongue is Vallate papillae.
Vallate papillae:
These are specialized taste buds that present in the posterior dorsum of the tongue.
They are the largest taste buds. They form a 'V'- shape structure.There number can vary between 7- 12.Therefore, the largest but least numerous papillae in the dorsal surface of the tongue is Vallate papillae.

Match the following explanations with the appropriate reasons for cellular reproduction.
Answer:
Organisms get larger and develop into different stages of life >> Growth and development
Heal wounds, replace damaged cells >> Replace cells
Organisms make more of the species to keep them from going extinct >> Reproduction
Explanation:
Growth refers to the irreversible process by which organisms/tissues/cells increase in size and mass. Moreover, development can be defined as the progression from earlier to later maturation stages (e.g. fertilized ovule develops into a seed that will produce a mature tree). Cell replacement is a natural mechanism that occurs when cells become aged or in response to external/internal damage. During cell replacement, cells are produced from other cells by cell division. Finally, reproduction is a key biological process by which organisms (called parents) produce new genetically related organisms (i.e., offspring). According to the mode of transmission of genetic information, reproduction can be divided into sexual reproduction (offspring are different from parents) and asexual reproduction (offspring are the same as parents).

Consider the two samples of sedimentary rock seen here.Predict which rock would be more likely to undergo physical weathering. Explain how and why.
A) Sandstone. Sandstone has more obvious layers of sediments.
B) Shale. Shale is fine grained and is more likely to dissolve in water.
C)Sandstone. Sandstone is made of large sand-like grains and is easily eroded by wind
D)Shale. Shale contains iron which is an element that easily combines with the oxygen in the atmosphere to produce rust.
Answer: A) Sandstone. Sandstone has more obvious layers of sediments.
Step by step explanation: As you take a look at the given pictures, you notice that (Sandstone) Is more closed off than (Shale). So whenever rain comes, rain will seep into the little openings of the rock shale has, causing it to break down.Same for strong wind, since shale isn't as compacted as Sandstorm, then shale will not last very long. Therefore making Sandstone being able to undergo more harsh conditions.
