1. Answer: 4.5 hour

The equation for time needed to prepare the diner is H/6 + H/18 = 1

To solve this question, you have to equalize the denominator of the equation. The greatest common multiple of 6 and 18 is 18, so you have to change the denominator to 18. The calculation would be:

H/6 + H/18 = 1

H/6 * 3/3 + H/18 = 1

3H/18 + H/18 = 1

4H/18 = 1

H= 18/4= 4.5

2. Answer: 9.2 grams

Halley measured samples of a metallic substance for an experiment on density with equipment that has lowest unit 1/10 gram or 0.1 gram. The equipment should not be able to differentiate unit lower than 0.1 gram, so it is not possible to have result such as 9.24 grams. or 9.244 grams.

3. To find the formula to find length of a rectangle from its perimeter you need to move the length(l) into the left of the equation. The calculation would be:

p = 2L + 2w

p-2w=2L

2L= p-2w

L=1/2p -w

The equation of I is right, but the equation of II and III is not.

I. L= 1/2p - w ----> right

II. L=(p - 2w) ---> wrong, should be 2L=(p - 2w)

III. L= P-2w / 2---> wrong, should be L= (P-2w)/ 2

From the options B is not part of the study of science is : ( B ) The ethics of new developments

Analyzing the evidence gotten from an experimental or research study is a core part of science because that way the scientist can determine if the results obtained are close to the predicted hypothesis or outcome.

Science involves the study of the natural world because all scientific experiments and researches are carried out by studying real life ( natural world ) as study cases. while the ethics of new developments is not controlled or determined by the scientist

Hence we can conclude that the ethics of new developments are not part of the study of science

Ivenika [448]

One who researches 'botany' is called a 'botanist'. Botany is one of the world's oldest natural sciences. initially, Botany protected all plant-like organisms inclusive of algae, lichens, ferns, fungi, and mosses in conjunction with actual flowers.

Darwin understood the centrality of development in a deep and profoundly vital manner, both for animals and for flora. His notebooks document his cautious studying and interest in animal embryology and plant leaf and floral organ morphogenesis.

Butterfly-pollinated plants usually have pretty flashy flowers in hues like crimson and purple. these plants do not have the quantity of pollen that bee-attracting flowers do, however they've huge components of nectar to feed the butterflies.

Answer: A Fixed Action Pattern

Explanation:

A fixed action pattern is an ethological term and off course a natural activity pattern that causes animals to act in a specific behavior pattern distinctive to their species. It is a pattern that is relatively unchangeable within the species and usually ends even when it is interrupted. You can say that, it is innate releasing mechanism or network where sign stimulus exists, once released from neural network; fixed action pattern leads to completion as well.
