<h3>
Answer: C. a balance and a beaker</h3>
Explanation:
A balance would be used to measure the weight, which in turn effectively measures the mass (more or less). Imagine that we have a brick that we know is 1 pound. If we have an object that needs 5 bricks on one side to balance it out, then we know the object is 5 pounds.
The beaker is used to measure the volume. It's basically a measuring cup that you would find in the kitchen.
To get the density, you divide the mass over volume.
For example, if you have a material that has a mass of 100 grams and it's volume is 20 cm^3, then its density is 100/20 = 5 grams per cm^3.
Answer:
Platelets would release signals to stimulate the production of more platelets
Explanation:
Positive feedback mechanism is one of the two types of feedback mechanisms (other being negative feedback mechanism) in which the products of a process stimulates more of that product to be synthesized or produced. In other words, the result of a reaction increases the secretion of more results.
In this case where the injured tissue of a cut initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. However, if this is a positive feedback mechanism as explained above, Platelets would release signals to stimulate the production of more platelets.
Coexist... They don't harm us... And they even protect us from other organisms outside our body
And in our guts they make vitamins :)
Plz give me brainliest
The white blood cells are responsible for engulfing foreign material such as debris and microorganisms in the blood and other tissues. There are types of white blood cells that are specialized in phagocytosis, these are the: (1) neutrophils and the (2) macrophages.
<em>Neutrophils are more abundant in acute inflammation and marcophages are more significant in chronic inflammation.</em>
Animal cells form animals
Plant cells form plants
