Add a drop of methylene blue solution and place a coverslip, make sure that bubbles are avoided i.e. coverslip should be placed in the inclined manner. Remove the excess solution and observe it under the microscope first under 4X and then under 10X.

Observation:

The cells observed are squamous epithelial cells. The small blue dots seen inside will be the bacteria from our teeth and mouth.

environmental scientists collect air samples so they can test the quality of the air, they start with rigid metal containers that are completely empty the air has been pumped out of them what happens to the pressure inside the container and the volume of the container as air enters it?

Answers

Answer:

Here's this. Let me know if that helps :)

Explanation:

The sampling procedures must be designed so that samples of the actual dust concentrations are collected accurately and consistently and reflect the concentrations of dust at the place and time of sampling. Sufficient number of 6-hour area samples in each distinct work area of the plant should be collected at locations which provide representative samples of air to which the worker is exposed. In order to avoid filter overloading, sampling time may be shortened when sampling in dusty areas. Samples in each work area should be gathered simultaneously or sequentially during a normal operating period. The daily time-weighted average (TWA) exposure of each worker can then be determined by using the following formula:

As the air which is pumped out of the empty rigid metal containers the pressure inside the container increases as well as the volume of empty container increases to occupy the space.

What are pressure and volume changes?

The container experiences changes in the amount of pressure and volume, when the matter is added or removed from a container. An increase is experienced when something is added to the container.

The increase in volume and pressure are observed because as the air is pumped out of the container it tries to spread out and volume increases as the particles starts to occupy the empty space present in the container. With the particles occupying volume of container, the air particles try to move faster and as a result hits the container harder which lead to increase in the pressure inside the container, and the volume of air pumped out of the container.

A) Outline the three stages of cell signaling.

B) The aldosterone hormone is released by the adrenal gland. Explain the target cells signal transduction pathway response to aldosterone.

Note: Please help Im on a time crunch!! <3

Answers

Answer:

A. The process of cell signaling includes three stages: reception, transduction, and response. in reception, a chemical signal binds to a cellular protein, typically at the cell's surface. In transduction, binding leads to a change in the receptor that triggers a series of changes along a signal - transduction pathway. In response, the transduced signal triggers a specific cellular activity.

B. When aldosterone hormone is released by the adrenal gland: first, the Endocrine System secretes hormones into the blood and hormones are transported within the blood and are distributed to target cells throughout the body, then any cell in the body with a receptor for the hormone is targeted, there is a relatively slo reaction time which could range from seconds to minutes to hours, the effect of the hormone released is usually felt throughout the body but the response is long - lasting from minutes to days to weeks and my continue after the stimulus is removed.

The best example of a keystone species from the available answer choices is:

А . Sea otter

A keystone species is an important pointer in any ecosystem that helps make sure that the ecosystem doesn't go extinct.

They have low functional redundancy which means that if there is a decline in the diversity of the ecosystem, then the traits are lost.

A sea otter is a good example of a keystone species because they are high on the food chain in the marine ecosystem as they are the predators and help reduce the number of sea urchins who eat the kelp.

This action of the sea otter ensures their survival in the ecosystem.

Therefore, the correct answer is option A

During spring/wet summer Blue herons feed on Frogs and Tadpoles while they predate/feed on lizards and snakes when the season becomes drier.

The predation habits of the Blue heron is affected by the changes in weather conditions year round, Blue herons can predate/feed on different preys such as ; eagle eggs, lizards, snakes and tadpoles.

The type of prey the Blue heron feeds on is solely dependent on environmental factors at each time of the year. Blue herons are found mainly on the shores of water bodies.

Hence the changes in environmental factors makes the Blue heron to feed on frogs during spring/ wet summer and to feed on lizards when the season becomes drier.
