A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth and moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle.

True or false: only a very small percentage of health care providers hold biased attitudes toward individuals who are obese.
posledela
False. If you search in Google Scholar or some other database using these keywords, you will see countless empirical, peer-reviewed research studies showing how healthcare providers are significantly influenced by their implicit biases regarding obese patients, leading to healthcare disparities.

Implicit bias refers to our unconscious decisions and perceptions of people, and if you want to learn more about it, I highly suggest you visit Harvard's Project Implicit online.

While implicit bias is pervasive, there still are some healthcare workers who are more explicitly biased towards their obese patients. This is also a serious problem.

Your skeletal stores calcium. How does the calcium get into your body
frosja888 [35]

The calcium get into your body through Vitamin D.

<u>Explanation:</u>

In order to make the bones healthy, calcium and phosphorus is very essential.  Calcium cannot be made by human body. The body only gets the calcium it needs, by means the food you eat, or from supplements. Vitamin D plays a major role in the absorption of calcium in human body. Calcium is a major mineral in a human body that helps in the proper working of body cells and nerves.

The quantity of the minerals like calcium, phosphorous,etc that are present in a segment of bone determines the density of bone. A percentage of 15 to 20 of calcium is absorbed from the diet that human intake. When the levels of vitamin D is low, there will be lower intake to calcium by gut. This causes the bones to become weaker.

A drug that prevents assembly of the mitotic spindle would cause the cell cycle to stall just after
noname [10]

Answer:

The correct answer will be option-A

Explanation:

Colchicine is the drug that prevents the assembly of the mitotic spindles which halts or stops the cell cycle.

The colchicine acts by inhibiting the microtubule polymerization thus mitotic spindles which takes place after the condensation of the chromosomes during prophase and pre-metaphase.

This acts as checkpoint which can halt the cell cycle at the phase of chromosome condensation.

Thus, option-A is the correct answer.

Desacribe an experiment to prove that carbon dioxide is essential for photosynthesis ?
disa [49]
Take two healthy potted plants. Keep them in a dark room for 2-3 days. Now place each plant in a separate glass. Get a cup containing potassium hydroxide by the side of the plants (the potassium hydroxide is used to absorb carbon dioxide). COver both plants with separate jars. Seal the jars so that the set-up-is-air-tight. Keep the plants in sunlight for two hours. Gently pluck a leaf from each plant. remove the chlorophyll from the leaves by boiling them in alcohol. Wash the leaves with water and then pour iodine solution over them.

We can conclude that the photosynthesis cannot be carried out without carbon dioxide. the leaf from the plant (which was the jar containing potassium hydroxide, which absorbed the carbon dioxide) turns blue black on iodine solution showing that starch is presented in this lead.

so this shows that carbon dioxide is necessary for the processs of photosynthesis to take place
