Explanation:
If water did not expand when freezing, then it would be denser than liquid water when it froze; therefore it would sink and fill lakes or the ocean from bottom to top. Once the oceans filled with ice, life there would not be possible.
These hydrogen atoms can come together in nuclear processes called fusion, which is the process that powers the sun, and through fusion, heavier atoms such as carbon and nitrogen are produced. These in turn undergo fusion to make even heavier atoms, and it is such processes that created all the atoms in the earth.
Answer:
It helps heal a bruise by producing the energy required to heal cells.
Explanation:
The mitochondria, which are responsible for cellular respiration, are also the powerhouses of the cells, and create the energy the cell uses.
The best way to destroy harmful germs that may be present in meat is to: cook to a safe minimum internal temperature.
Further Explanation
Meat is considered a potentially hazardous food meaning it is susceptible to microorganism including harmful bacteria. What makes this food susceptible is that the nature, characteristic and composition of this food is ideal for the bacteria to live and grow. Raw meat contains high-moisture, protein, and a good pH which support growth or toxin formation of pathogenic bacteria. Therefore to keep it safe for consumption food safety organizations require time-temperature control in handling these type of food.
Time-Temperature Control (TCS) is required for the safety of consumers because keeping the food at the proper temperature can slow down or destroy the bacteria.
Freezing
Freezing cannot destroy pathogenic bacteria and the toxins they produce. It can only make pathogenic bacteria inactive thus making the bacteria unable to produce toxins. Therefore, when food placed into the freezer is already contaminated then thawed, it will harbor the same harmful bacteria. Most bacteria are inactive at temperatures below 40 °F.
Cooking
When cooking raw meat and poultry, food handlers must ensure that the meat’s internal temperature has reached the safe minimum temperature and rest time. A food thermometer must be used to check the temperature. When roasting, the oven temperature must not be lower than 325 °F. Cooking to a safe minimum cooking temperature destroys harmful bacteria that cause food borne illness.
<h3>Safe Minimum internal Temperature and Rest Time for Meat
</h3>
- Poultry (All poultry, minced, whole, chopped and stuffing) - 165ºF
- Beef, Pork, Veal, and Lamb (chops, roasts, steaks) - 145ºF with a 3 minute rest time

Answer:
Embryological evidence
Explanation:
Deuterostomes is a group that includes echinoderms, hemichordates, and chordates. Although these animals exhibit a wide variety of body plans, they share a mouth secondarily formed during embryo development, which it is believed to be an evolutionarily derived character present between a common ancestor and all its descendants (i.e., a synapomorphy). This oral cavity is formed by the invagination of the ectoderm layer opposite to the blastopore of the gastrula.
