The surface area to volume ratio of the cubes is given below:
Cube 1: Surface area to volume ratio = 6Cube 2: Surface area to volume ratio = 3Cube 3: Surface area to volume ratio = 2What is the surface area to volume ratio of the cubes?The surface area to volume ratio of the cubes is calculated from the respective formulas for surface area and volume of cubes as follows:
The surface area of a cube = 6 * s²
The volume of a cube = s³
where s is the length of a side or edge of a cube
Cube 1:
Surface area = 6 * 1² = 6 cm²
Volume = 1³ = 1 cm³
Surface area to volume ratio = 6 / 1 = 6
Cube 2:
Surface area = 6 * 2² = 24 cm²
Volume = 2³ = 8 cm³
Surface area to volume ratio = 24 / 8 = 3
Cube 3:
Surface area = 6 * 3² = 54 cm²
Volume = 3³ = 27 cm³
Surface area to volume ratio = 54 / 27 = 2

In the experiment shown below, if the temperature of the room rose, what would happen to the time taken for the litmus paper to turn blue?
Answers
The time taken will be more for the litmus paper to change its color from red to blue.
What is the use of litmus paper?
An inspector can measure the acidity or basicity of a solution by using litmus paper, which turns red at pH levels below 5 and blue at pH levels above 8. Using litmus paper, which compares minute color variations to a color chart to identify pH levels, allows for more accurate pH determinations.
The rise in temperatures favors the acidic pH of the litmus paper. A solution's molecular vibrations increase as its temperature rises, which causes the solution to ionize and produce H+ ions. Acidic behavior increases with the amount of H+ ions. The pH level of the solution alters as a result of temperature variations. As a result, the pH drops as the temperature rises.
Hence, the litmus paper takes more time to turn blue in color due to the temperature rise.

The correct answer is it will take some more extra time for litmus paper to turn blue.
How pH affects with temperature?
pH decreases with increase in temperature.
• It means temperature and pH value both are inversely proportion.
• Neutral is 7. Less than 7 of pH value it is acidic and more than 7 then it implies it is basic.
• To support our answer added one image for illustration below
From above table we can conclude as temperature grows pH value will decrease.

Natural selection is the most important mechanism of evolution associated with reproductive success (Option 2).
What is natural selection?Natural selection is the main evolutionary mechanism by which species adapt to changes in environmental conditions. This process (natural selection) is based on the differential survival and reproduction rate of organisms that better fit environmental conditions.
Therefore, we can conclude that natural selection represents the main evolutionary process for which a species can survive and differentially reproduce in a given environment, thereby confirming an adaptive advantage to the certain individuals in a population in nature

Answers
Answer:
B
Explanation:
water has high specific heat value
Even if the density seems to be altering the effect of temperature, the degree of hydrogen bonding decreases as the temperature rises. Thus, option B is correct.
What role of hydrogen bond to maintain body temperature?The movement of molecules, or their kinetic energy, is measured by temperature. The temperature rises as the motion and energy levels rise.
The body's water plays a crucial role as a thermoregulator, controlling body temperature by assisting in heat dissipation.
When the body becomes too hot, water is lost through sweat, and heat is removed from the body when this sweat evaporates off the skin's surface.

The ability to roll the tongue is due to a dominant gene (R). If you cannot roll your tongue, you must not have curly hair and be homozygous recessive (RR). If the trait we're interested in is the inability to roll the tongue, then homozygous dominant females are represented by (n):D) filled circles on the pedigree.
Homozygous for a particular gene means that you inherited the same mutation. This is another heterozygous genotype in which the allele is specific. People with recessive tendencies, such as blue eyes or red hair, are consistently homozygous for this gene. If the two mutations are different, they are heterozygous for that gene.
For example, being heterozygous for hair color means having one red hair allele and one brown hair allele. The relationship between the two alleles affects the changes expressed. Homozygous and heterozygous are phrases that can be used to describe pairs of alleles. People who carry the same allele (RR or rr) are called homozygous.

Answers
Both Cestode and trematode have mode of infection as consumption of contaminated food. Cestode is acquired by ingestion of meat from hosts and trematode is via contaminated food like raw fish, crustaceans, etc.
What are Cestode’s economic implications?These tapeworms are the least helpful creatures. But these tapeworms also have a very limited economic impact. These tapeworms contribute to the harvesting of soil’s increased fertility through a natural process. These worms function as organic fertilizers.
What is the Cestode’s mode of infection?Meat from intermediate hosts is frequently consumed in order to acquire adult cestodes. Eggs of origin can cause an extraintestinal infection with larvae. Identification of eggs and segments (proglottids) in feces is used to diagnose an adult cestode infection.
What method does a trematode use to spread infection?Humans become infected by foodborne trematodes after eating tainted food (raw fish, crustaceans or vegetables. Infection can induce severe liver and lung illness, which together are thought to account for 2 million years of life lost to disability and death globally each year.
What distinguishes a trematode from a cestode?Cestodes lack a digestive tract and have a tape-like, segmented body. Trematodes have an imperfect digestive system and resemble leaves. Cestodes typically need two hosts, whereas trematodes typically need three, to complete their life cycles.
