The amount of water that condensed at the top of the terrarium change as plants sprouted and grew because water, oxygen and nutrients are  very essential elements for growth.

The plant cells grow in size by cell enlargement which in turn requires water. Turgidity of cells helps in extension growth. Thus, plant growth and further development is intimately linked to the water status of the plant. Water also provides the medium for enzymatic activities needed for growth. Oxygen helps in releasing metabolic energy essential for growth activities. Nutrients (macro and micro essential elements) are required by plants for the synthesis of protoplasm and act as source of energy.

Thus as plant grows it needs more water to provide to it's larger plant body and which causes decrease in the amount of water that condensed at the top of the terrarium.

Traits are bodily determined functions of an organism. Each allele is chargeable for a selected phenotype that makes up a trait. A dominant trait is the only one that is expressed over any other in a heterozygous kingdom i.e. the mixed kingdom of the 2 one-of-a-kind alleles that encodes the 2 one of kind developments respectively.

When the 2 one of a kind alleles integrate withinside the organism's genotype, the dominant trait (hornless) will specific itself over its contrasting trait (horn),The allele that encodes hornless-ness is stated to be the dominant allele at the same time as hornless-ness is the dominant trait.

Answer:

b. developing a hypothesis

The first step of the scientific method usually involves making observations. Therefore option D is correct.

Observations are systematic and objective observations of the natural world. Scientists use their senses or specialized tools to collect data and gather information about a particular phenomenon or problem.

These observations serve as the foundation for scientific inquiry and help researchers identify patterns, trends, or potential relationships between variables.

From these initial observations, scientists can then move on to formulating a hypothesis (b), which is a testable explanation or prediction based on existing knowledge and observations.

The scientific method guides researchers in a structured approach to understanding the natural world and conducting experiments to test their ideas.

Therefore option D is correct.

Since the process of hydrogenation contributes hydrogen atoms to oil, this will reduce the amount of fatty acids and increase the amount of saturated fatty acids in the oil.

Sustainability is the idea that people may live on Earth and utilise resources without destroying them or affecting future generations. The biological variety, food production, average global surface temperatures, CO2 concentrations, human population, and resource depletion are the five main environmental indicators that might point people in the direction of sustainability.

The foundation for determining sustainable yield is the ratio of the water level decline in the well to the pumping rate, the amount of drawdown the well exhibits for a particular pumping rate over time, and the recovery rate. Data from aquifer tests are typically more trustworthy the longer they are conducted.

Example is a fish that can be kept alive forever because they can be nourished by the underlying natural system's regenerating abilities.

Tooth extractions are carried out by dental and oral specialists for various reasons. A painful tooth or a tooth that has been significantly affected by decay may be the problem. Sometimes a dentist will extract a tooth to make room for dental prostheses or other devices.

When the situation becomes increasingly complicated, an oral expert rather than a dental professional may need to extract a tooth. They typically remove wisdom teeth or third molars.

The dental professional or specialist will initially numb the tooth to gradually relax the patient. Even though tooth extraction may still be distressing, it may be essential for relieving dental pain and preventing further problems.

How does hearing work?

It's a little tough to ELI5 without using using the names of the particular organs but here goes:

Sound is nothing more than a wave of air pressure. In other words, it fundamentally involves changing degrees of energy-based air pushing and tugging. Additionally, it is because to this that sound cannot travel in a vacuum. When these waves reach your ear, they first come into contact with the "tympanic membrane," which vibrates and transmits these vibrations to the malleus, incus, and stapes, three small bones (Latin for hammer, anvil, and stirrup).

The waves will subsequently be transmitted via the bones' vibrations to the "cochlea," a spiral-shaped organ filled with fluid. The air pressure wave has so undergone many transformations at this point. Air pressure was followed by mechanical vibrations and is now "fluid pressure." The spiral-shaped cochlea is lined with neurons all the way around. Depending on the fluid pressure waves' intensity, frequency, etc., the cochlea will have to travel a particular distance. Based on these fluid waves, these neurons will then activate, sending information to your brain.

Your brain then decodes these messages to produce the "sound" that you hear. Although I'm not convinced this is the greatest ELI5, this is the main idea.

In essence, your ear works as follows:

Air pressure waves enter the ear, transform into mechanical vibrations, transform into fluid pressure waves, which signal neurons and cause those neurons to fire electrical impulses that communicate with the brain the sound you are hearing.

Cheers,

Answer:

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

Answer:

As the cell enters meiosis 1, it's DNA replicates in S phase and then reduces to half when the cell splits into two. Hence, the amount of DNA remains 10 pg.

During meiosis 2, there is no DNA replication but only division between cells, leading to 5 pg of DNA in all four daughter cells.

So, the correct option is '10 pg and 5 pg respectively'

What evidence from the experiment shows that conduction occurred? In your answer, be sure to include the materials involved in the transfer of heat through conduction.

Sample Response: The melting of the chocolate pieces one by one showed that it was caused by heat flowing through the foil bridge. The transfer of heat happened between the foil bridge and the chocolate pieces because they were touching each other.

The conduction was made by the foil which was touching the chocolate made the chocolate slowly melt because of the tea light giving heat to the foil the foil conducted it to the chocolate causing it to melt. Thus, option "C" is correct.

Conduction refers to the transfer of the energy from one end to the other end from the conducting material. Heat energy, and electric energy all of these can conduct. For example - heat transfer from one end of the road to another.

Convection refers to the process in which heat energy is transferred to the liquid in various manners. For example - a geyser transfers the heat energy to the water.

Radiation refers to the transfer of heat in the form of a heatwave. For example - transferring of heat from the light bulb and heater.
