Assuming the stomata are open to the same degree, the rate of transpiration should _____ on a rainy day compared with a sunny day, because the relative size of the H2O concentration gradient from the inside to the outside of the leaf would _____.a) increase: increaseb) decline: decreasec) increase: decreased) decline: increasee) remain the same: not change
Answers
Answer:
decline: decrease
Explanation:
Transpiration is the loss of water from stomata by the process of evaporation. It occurs by the process of diffusion and is driven by the concentration gradient of water vapor. The higher the concentration gradient between air and leaf cells, the higher is the rate of diffusion of water.
On a sunny day, the rate of transpiration is higher since air is less humid and the concentration of water inside the leaf is higher. On the other hand, the air is more humid on a rainy day. The increased water vapor content of air reduces the concentration gradient between air and leaf cells. The reduced concentration gradient decreases the rate of transpiration.

B) Mutations can be positive and produce organisms with improved traits.
C) Mutations can be fatal to the organism that has a mutation, if the mutation is in a critical gene.
D) Mutations can be silent, and not affect the organism that has them, if the mutation is in a non-critical area.
Answers
Answer: The correct answer is- A) Mutations must be present in parents and then passed to offspring.
Mutation can be described as the permanent change in the genetic material ( DNA) of an organism. It can be beneficial or harmful to the life form. Mutations can be heritable ( that is passed from one generation to the next) or non inheritable ( not passed from parents to offsprings).
A silent mutation ( change in the nucleotide sequence without any change in the amino acid sequence) that does not show any observable effects in the phenotype of the organism.
Thus, only option A) is not true about mutation.
All the statements are true about mutations except Mutations must be present in parents and then passed to offspring.
Thus, An organism's observable traits, or phenotype, may or may not change as a result of a mutation. Evolution, cancer, and the maturation of the immune system, including junctional variety, are among the normal and malignant biological processes in which mutations play a role.
All genetic variety originates from mutation, which also provides the basis for the action of evolutionary forces like natural selection.
Sequence changes can take many distinct forms as a result of mutation. Gene mutations can have no effect, change the gene's product, or stop the gene from working fully or correctly. Non-genic areas are likewise susceptible to mutation.
Thus, All the statements are true about mutations except Mutations must be present in parents and then passed to offspring.

As water moves from the roots up through the stem of a plant adhesion is a property of water that enables this to happens. The characteristic of water causes adhesion is hydrogen bond. Thus, option D is correct.
What is water?
Water has been defined as the water present in the underground water below the soil as well as in the crack of the earth. The percentage of freshwater in the world would be 30%. There are mainly three types of groundwater and these are known as hand-dug wells, springs, and drilled boreholes.
The water stored under the ground has been obtained from rain and stored in ground so that it can be used later. Ground water has observed very clean and fit for drinking and the reason has been the soil present on top and work as filter and the groundwater is free from all microorganisms.
The use of groundwater is just to wash dishes and cooking utensils in cold, soapy water,Use a disinfectant wash cloth to clean the refrigerator. Rinse and wash contaminated clothing separately.
Therefore, As water moves from the roots up through the stem of a plant adhesion is a property of water that enables this to happens. The characteristic of water causes adhesion is hydrogen bond. Thus, option D is correct.

Breathing and cellular respiration are similar in nature because major part of both the processes involves oxygen.
Further Explanation:
The glucose is broken down by a process called cellular respiration. The cellular respiration occurs in mitochondria of animals and plant. Cellular respiration is referred as a total collection of methods and metabolic process that occur in cells. The cellular respiration is a process by which the cells of the body breakdown the food to produce energy. This energy is required for all the metabolic functions as well as the physical role of the body. Cellular respiration can be dividing into three stages
- Krebs cycle
- Glycolysis
- Electron transport chain
Breathing involves inhalation of air which is rich in oxygen and exhaled out carbon dioxide because of the breathing cells get enough oxygen for the process of cellular respiration. Carbon dioxide is produced in the body by the process of cellular respiration. Both the process use oxygen and produced carbon dioxide.

Final answer:
In a food web, each step in the transfer of energy and matter is referred to as a trophic level. These steps provide an illustration of energy flow within an ecosystem, with examples being producers, consumers, and higher-level consumers. The transfer of energy - although more complex - is more accurately depicted in a food web than in a food chain.
Explanation:
The term for each step in the transfer of energy and matter within a food web is known as a trophic level. These are the different steps in a food web or chain at which the transfer of energy occurs. An example of these levels can include producers, primary consumers, and higher-level consumers, each playing specific roles in the overall energy flow.
A food chain is a linear system that offers a simplified view of energy transfer within an ecosystem, while a food web offers a more complex and holistic view of the multiple trophic interactions and energy transfers within an ecosystem.
It is important to mention that energy transfer efficiency influences the structure and dynamics of ecosystems. This is due to the fact that with each energy transfer, some energy is lost, often in the form of heat. This limits the length of food chains within a food web.
