Answer:</h2>
Generally, <u>D) non-metals are gases</u> which are at room temperature.
<h2>
Explanation:</h2>
Those metals which lack the property of the metal are called as non-metal. Usually they are characterized by the following features:
- Nonmetals don't conduct electricity through them.
- Nonmetals don't allow heat to pass through them.
- They don't show ductility and malleability.
- The nonmetals not only include gases but there are some solids which do not exhibit the above mentioned characters are also nonmetals. Some of the solid nonmetals includes graphite, carbon, wood, and so on.
Thus, from the above data, it can be inferred that option D which states that gases at room temperature is considered as most suitable answer for non-metals, as option A, B, and C are characteristic of metals.
Answer:
Three factors that affect my daily food choices include:
1. Taste
2. Length of time for preparation
3. Method of preparation.
Explanation:
When making choices for food, I tend to take several factors into consideration. Some of these factors include;
1. The taste of the food: If the food tastes good and is not too spicy I am more inclined to choose such food.
2. Length of time for preparation: Especially on stressful days, I tend to consider the length of time required to prepare a healthy meal. If it takes so much time I am more inclined to eat fast food which is not a good choice.
- To change this negative outcome, I hope to plan my affairs for the day and prepare healthy meals beforehand, which could be stored in the refrigerator and reheated when I need it.
3. Method of Preparation: Some foods require paying attention to details. For example, food that uses up, a lot of vegetables would require thorough washing to prevent particles in the food. Busy days also get me exhausted with no strength to pay attention to these protocols.
- To turn this around, I hope to employ the help of a family member to make the process easier.
- I also hope to process most of my ingredients and keep them ready for use so that I would not have to do a lot of processing while cooking.
This is an organ that served a purpose in the distant ancestor of an organism, but is not longer pertinent in the presently existing, recently evolved, organisms.
Answer:
1. D. Only DNA contains genetic information
2. D. Nitrogen and Phosphorus
Explanation:
1. Lipids are insoluble in water unlike other molecules. It stores energy within the fat tissues and cushion internal organs against trauma.
Carbohydrates are sugar units such as monosaccharides, disaccharides molecules which makes up starch that is fuel to your cells.
DNA is a type of nucleic acid that contains genetic information which influences your personal characteristics.
2. The family Rhopalodiaceae has the ability to perform nitrogen fixation, which allows diatoms to fix atmospheric nitrogen. And phosphorus has been found in some diatom species in the Black sea region which does not affect its reproduction rate and also helps in carbon cycle.
