The following statement is False. There is a constant flow of energy takes place from plants to plant eating animals to flash eating animals in the form of food and 90% of energy is lost as heat .
Hence, Option B is correct.
What is 10 % Law ?Lindemann in 1942 proposed the 10% law of energy flow in ecosystem. According to 10% law if the net primary productivity is taken to be 100% in producers ( first trophic level ) then only 10% of potential energy of plant material is actually assimilated by herbivores as food .during this act by herbivores 90% of energy is lost as heat (thermal heat ) to the environment .
Similarly only 1% of the potential energy of primary consumers is assimilated by carnivores ( secondary consumers ) and the rest 90% of energy of carnivores is lost as heat to the environment . Thus, during energy flow in ecosystem the energy fixed in one level is only 10% of its previous level and 90% of energy is lost as heat in each trophic level.
Thus it it concluded that there is a constant flow of energy takes place from plants to plant eating animals to flash eating animals in the form of food and 90% of energy is lost as heat .
Hence, Option B is correct.

What part of henry’s cochlea may have damaged hair cells? What part of henry’s cochlea may have functional hair cells?
The henry's may have damaged and functional hair cells of cochlea in organ of corti.
Hearing and the Cochlea:
Sound waves that enter the ear go through the external auditory canal before they strike the eardrum and cause it to vibrate. The incus receives sound vibrations from the malleus, also called "hammer," which is linked to the eardrum, and sends them on to the stapes.The stapes is a framework that moves the oval window in and out. This motion is received by the cochlea, a fluid-filled snail-like structure that houses the organ of Corti, the hearing organ. Small hair cells make up the lining of the cochlea. These cells convert vibrations into electrical impulses that sensory nerves then transmit to the brain. the Corti organ, which has four rows of hair cells. On the left, there is an inner row, and on the right, there are three outside rows. The stapes first sways against the oblong glass. This causes sound waves to travel into the cochlear fluid and move the organ of Corti.Lower frequency sound resonates with fibers towards the cochlea's upper end. Higher frequencies elicit a response from those near the oval window.Learn more about the Structure of ear with the help of the given link:

Exothermic versus endothermic
An endothermic reaction is taking place in a test tube. what would you expect to feel when you touch the outside of the test tube?
If an endothermic reaction is taking place in a test tube, the temperature will decrease which can be felt when we touch the outside of the test tube.
An Exothermic reaction is a chemical reaction which involves the release of heat energy in the surroundings. The temperature of the surrounding resultantly increases.
An endothermic reaction is a type of of chemical reaction in which energy is absorbed from the surrounding. This results in a decrease in the temperature of the surroundings. When an endothermic reaction takes place in test tube the temperature of the surrounding, which is the wall of the test tube, will decrease and this can be felt by touching the outside of the test tube.

Carbon atoms can form
A. one double covalent bond
B. two triple covalent bonds
C. four single covalent bonds
D. three double covalent bonds
Answer:
c
Explanation:
The correct answer is c. four single covalent bonds.
Covalent bondsThe exchange of one or more pairs of electrons between two atoms forms a covalent connection. The two atomic nuclei are drawing these electrons in unison. When there is insufficient space between two atoms' electronegativities for an electron transfer to take place and create ions, a covalent bond is formed. Bonding electrons are shared electrons that are present in the region between the two nuclei. The Covalent bonds pair serves as the "glue" that binds the atoms in molecular structures. To identify the covalent bonds pair from the lone pair electrons, the covalent bond is depicted in a Lewis structure as a dash. The nonbonding electrons in Lewis structures are represented as pairs of dots close to the atomic symbols for the atoms.

When taking blood pressure, the sounds heard when the pressure cuff is released are due to ________.
When taking blood pressure, the sounds heard when the pressure cuff is released are due to Rising of the Systolic Pressure above the cuff pressure.
When deflating the cuff, the first sound is due to the Systolic Pressure. The cuff pressure is released by the opening of the airflow valve in a counterclockwise direction. The sound heard is a Sharp Tapping sound.
Systolic pressure is the pressure generated due to contraction of heart and Diastolic pressure is generated due to the relaxation of the heart.
Blood Pressure is measured by a device called Sphygmomanometer.

Why do humans have a strong impact on the fast carbon cycle?
Burning fossil fuels or cement has relatively little of an influence on humans in terms of producing carbon dioxide. The general people has been duped into believing we are a major factor in the greenhouse effect.
The biggest misconception regarding the movement for people to emit no net amount of CO2 is that natural supplies of this plant nourishment dwarf our emissions. This indicates that even if all people disappeared overnight, atmospheric CO2 levels would not significantly drop.
The statistics on the steady increase in CO2 throughout the heaviest periods of the global lockdown, which significantly restricted any human-sourced emissions, will give you a decent idea of this.
As for the so-called greenhouse gases, CO2 naturally occurs in water vapor, which makes up more than three times as much of the GHG as CO2. This indicates that the human component of the GHG is 0.6 percent.
When you take into account how little human emissions are in the grand scheme of things, you have to stop and wonder if any efforts you make to lower your emissions are in vain.

Carbohydrates carry out the body's method for transporting energy. Several biological systems, including the brain and blood cells, rely on glucose as an energy source.
Even though most ingested glucose is transformed into energy, part of it is converted into ribose and deoxyribose, which are crucial components of significant macromolecules, including RNA, DNA, and ATP.
