Design a controlled experiment to determine whether earthworms change the forest ecosystem.

Biology

Orlov [11]1 year ago

"The experimental hypothesis may be that if Asian worms are introduced into a <u>deciduous forest</u>, the soil's nutritional composition will alter. The control group would consist of a region of the forest that has been worm-free in some way. But in order to serve as a control, this forest would experience the same amount of sunshine, heat, and precipitation. In order to determine if Asian worms actually have an impact on the forest ecology, the scientists could then analyze the amounts of nitrogen, phosphorus, and sulfur in the two portions of the forest."

Deciduous forest- A deciduous forest is one that is mostly made up of trees that shed their leaves in the fall.

Light rays passes through the pupil in the eye and activates the neurons in the retina. The light wavers that are from the reflection of the object are transformed into neural impulses or transduction then action potentials are released when electrical charges are sent through the neurons. Excitatory neurotransmitters are supplied when action potential goes to the axon terminal and the thalamus routes the neural message from the retina elsewhere in the brain. Feature detectors organize the visual projection of the object.

As part of an experiment on circadian rhythms, a laboratory rat’s brain has been lesioned. The animal is now falling asleep and
Sergio039 [100]

Answer:the part of the brain that has most likely been damaged in this experiment is the suprachiasmatic nucleus (SCN) found in the hypothalamus of the brain.

Explanation:

circadian rhythms are behavioural changes that respond to light and darkness in an organisms environment. The sleep-inducing wake cycle is a good example of a circadian rhythm. In the experiment, the disruption of the mouse SCN led to development of imbalances in the circadian rhythm of sleep and wake cycle leading to falling asleep and waking up at random times of the day and night. I hope this helps. Thanks

Be able to compare/contrast humoral immunity with cellular immunity.
aksik [14]

Solution:

The difference between them are:


The humoral system of immunity is also called the antibody-mediated system because of its use of specific immune-system structures called antibodies. The first stage in the humoral pathway of immunity is the ingestion (phagocytosis) of foreign matter by special blood cells called macrophages. The macrophages digest the infectious agent and then display some of its components on their surfaces. Cells called helper-T cells recognize this presentation, activate their immune response, and multiply rapidly. While,


The cell-mediated immune response involves cytotoxic T-cells, or killer-T cells. Body cells that have been infected by foreign matter often present components of that material on their surfaces. Killer-T cells recognize these displays and respond by ingesting or otherwise destroying the infected cell. Killer-T cells are also important in the body's defenses against parasites, fungi, protozoans, and other larger cells that might have found their way into the body. The killer-T cells recognize these large invaders by their foreign proteins and then destroy them.  

This is the required answer.
