What is a lymph node?

No lymph nodes exist in the central nervous system. The lymph nodes are more likely to gather in three locations on each side of the body.

The inguinal nodes in the groin, axillary nodes in the armpit, and cervical nodes in the neck are where these sites are found.

The typical lymph node is enclosed by a connective tissue capsule, which divides it into lymph nodules. The lymph nodules, which are dense aggregations of lymphocytes and macrophages, are divided by lymph sinuses.

Therefore, there are several locations throughout the node's perimeter where afferent lymphatics, which carry lymph there from the periphery and enter the node on its convex side, may be found.

A classmate states that both energy and matter can be created during photosynthesis and cellular respiration. Is this true? Explain

Answers

No, the chemical equations for both processes are evidence that matter and energy or neither created nor destroyed

Energy and matter are also produced during photosynthesis.Chemical energy in the form of glucose and matter in the form of oxygen gas are produced during photosynthesis.Since these are the results of the reaction, they are regarded as process outputs.

Can both energy and matter be created during photosynthesis?

Some cells employ a process called photosynthesis to convert light energy into food.Because it enables plants to produce the food required for the rest of the ecosystem, photosynthesis is crucial.Producing organisms, or those that grow their own sustenance, are plants.The foundation of the ecosystem is formed by producers, who transform solar energy into chemical energy in the form of food for themselves and other ecosystem inhabitants.Although many ecosystems are dominated by plants, other organisms are also capable of photosynthesis.Some bacteria and algae are capable of photosynthesizing, and these organisms are the producers in their ecosystem. A biological process called photosynthesis consumes both matter and energy.The world's physical components are made of matter.The capacity to perform work is energy.By use of various mechanisms, matter and energy can be switched for one another.On the other hand, neither matter nor energy can be generated nor destroyed.The first law of thermodynamics is that they constantly evolve into new forms.All processes in the universe operate in this manner.Energy can be transformed into a variety of forms.Several instances include:Chemical drivekinetic energythe potential energy of gravityelastic force The substance and energy persist even after an organism dies.Instead, they are changed into other forms.For instance, both matter and energy are components of plants.Fungi and bacteria in the soil aid in the breakdown of a plant's internal substance into its constituent parts when it dies.These can be used by newly sprouting plants by being recycled into the soil.As a result, neither the energy nor the substance is wasted; rather, they are transformed into new forms.

Where are the answers?

Explanation:

Answer: Earths orbit around the sun, solar energy, and volcanic eruptions

Explanation:

Earths orbit: At other times, the ellipse is more pronounced, so that the Earth moves closer and further away from the Sun in its orbit. When the Earth is closer to the Sun, our climate is warmer and this cycle also affects the length of the seasons.

Solar energy: Solar produces less life-cycle GHG emissions than conventional fossil fuel energy sources.

Volcanic eruptions: Volcanic eruptions of this magnitude can impact global climate, reducing the amount of solar radiation reaching the Earth's surface, lowering temperatures in the troposphere, and changing atmospheric circulation patterns.
