Answer:

Apron, gloves, closed toe shoes, goggles. Kim should also tie long hair back if she has it and should roll long sleeves up.

Explanation:

Aprons, closed toe shoes, and goggles will prevent any of the liquid being heated from burning and harming her skin or eyes.

Gloves are needed to protect her hands from heat and the liquid as well.

Long hair should be tied back to prevent it from being burned or harmed from the liquid, and long sleeves need to be rolled up to prevent them from being caught on fire or dragging into the liquid.

Andrew [12]
I think you forgot to give the options along with the question. i am answering the question based on my knowledge and research.

What prediction(s) can researchers make based on the egg-viability hypothesis? Select all that apply.The probability of hatching
ycow [4]

From the Egg viability hypothesis, we can predict the following;

A. Probability of hatching failure will

be higher for eggs laid later within a clutch.

This is because viability of unincubated eggs decline overtime.

B. The probability of hatching fail will be higher for eggs laid later within a clutch.

This is because large clutch affects or changes nest micro-climate which result to increase in water loss during incubation period.

Cost price=38 and profit 15%find the selling price and profit​
shutvik [7]

Selling price (S) = 43.7

Profit = 6.7

Explanation:

Given parameters:

Cost price = 38

Profit = 15%

Unknown:

Selling price = ?

Profit = ?

Solution:

The selling price is the amount a particular good is sold.

  Selling price = Cost price + profit

The profit is the gain on goods sold.

    Profit = Selling price - cost price

We have been given the profit percent;

   %Profit = \frac{S.P - C.P }{C.P }  x 100

 15 =  \frac{S - 38}{38 }  x 100

 

  Selling price (S) = 43.7

 Profit = selling price - cost price = 43.7 - 38.00 = 6.7

statuscvo [17]

Answer:

D. all of the above

Explanation:

Australopithecus (first ape-man): Australopithecus is considered as the connecting link between apes and man as they shared the characteristics of both. The fossil records shows that they appeared around 5 million years ago. <em>Australopithecus africanus</em> was about 1.5 meters high and had human as well as ape like features. It was with bipedal locomotion, omnivorous in their diet and had erect posture. It had human like teeth with small canines and large chewing teeth. The brain was more like an ape with the brain capacity of about 500 cc similar to that of an ape. He lived in caves, had projected  brow ridges with no chin. Its believed that <em>Australopithecus africanus</em> gave rise to <em>Homo habilis</em> about 2 million years ago.

The earliest species of Homo genus is <em>Homo habilis</em>. They were skill full man also called as handy man or the tool maker. He had erect posture with bipedal locomotion. The teeth were like modern man. He was skilled and made tools with stones. Slowly with evolution the prognathous face changed to orthognathous in cro magnon (<em>Homo sapiens fossilis</em>).

the respiration in human start from breathing.the oxygen is inhale and passes through larynx and reaches upto trachea and it goes in the bronchus.it is also divided into bronchoioles. it leads into lung

the bronchoioles that enter in the lung lead to small air sac called alveoli and it exchange gases and here exchange of gas occur and carbon dioxide is transported back to nostril through same passage and the canbondioxie is exhaled.in this way the process of respiration is completed
