Living cells are classed as either prokaryotic or eukaryotic. Which of the following characteristic(s) identify both cell types, eukaryotic cells and prokaryotic cells? Select all that apply. have a nucleus contain cytoplasm comprise most multi-celled organisms mostly single-celled organisms have membrane-bound organelles are the smallest unit of living matter are produced by division of another cell contain DNA
Answer:
have a nucleus - Eukaryotic
contain cytoplasm - Both
comprise most multi-celled organisms - Eukaryotic
mostly single-celled organisms - Prokaryotic
have membrane-bound organelles - Eukaryotic
are the smallest unit of living matter - Both
are produced by division of another cell - Both
contain DNA - Both
Explanation:
1. Eukaryotic cells are cells that possess a membrane-bound nucleus that houses their genetic material.
2. Both eukaryotic and prokaryotic cells have a cytoplasm, which is the gelatinous substance where all other organelles and substances are found.
3. Most multicellular organisms comprises of eukaryotic cells.
4. On the other hand, most single celled organism, are Prokaryotic.
5. Eukaryotic cells, in addition to the possession of a membrane-bound nucleus, they also possess membrane-bound organelles e.g mitochondria, endoplasm reticulum.
6. Cells, generally, are the smallest unit of living matter. This comprises of both eukaryotic and prokaryotic cells.
7. Likewise, all cells arose from already preexisting cells according to the cell theory. Therefore, both eukaryotic and prokaryotic cells are made by the division of another cell.
8. Both prokaryotic and eukaryotic cells have a genetic material like DNA where they store genetic information.

Are the seasons (summer or winter) the same in the Northern and Southern Hemispheres
at the same time? When it is summer in the Northern Hemisphere, what season is it in the
Southern Hemisphere?
Answer: No they don't occur at the same time
Summertime in the northern hemisphere happens when it is winter in the southern hemisphere, and vice versa.
The tilt of the earth causes the seasons. The northern hemisphere's summertime means that the northern part of the earth gets more sunlight compared to the southern half, so the southern half experiences winter.
With the tilt held at the same angle, the earth revolves to another point in space, so that the northern hemisphere receives less sunlight and the southern hemisphere gets more. So the seasons swap.
Answer: Winter
Explanation: The tilt of the Earth determines the seasons for the Northern and Southern Hemisphere. When the Northern Hemisphere tilts toward the Sun, it experiences summer. At the same time, the Southern Hemisphere tilts away from the Sun. It experiences winter.

What are the similarities between the different models used to quantify the growth of a population
Answer:The models used are exponential growth models and logistic growth models. They are similar because they both grow slowly. How does carrying capacity affect reproductive rates?In the real world, with its limited resources, exponential growth cannot continue indefinitely. Exponential growth may occur in environments where there are few individuals and plentiful resources, but when the number of individuals becomes large enough, resources will be depleted, slowing the growth rate.

Mary loved having her own garden and would often spend many hours tending to its care. She was meticulous in watering the plants,pulling the dreaded weeds, and harvesting the fruits and vegetables as they ripened. Her garden consisted of corn, tomatoes, greenbeans, okra, zucchini, squash, lima beans, watermelon, and cantaloupe. Often, the garden would produce much more than Mary andher daughter, Sue, could eat. Rather than waste the delicious food, the ladies would spend hours on the weekend canning the excessvegetables and fruit. It was something they had done for many years. On this particular occasion, Sue noticed that the pressure cooker,the instrument used to sterilize the canned food, did not seem to be acting quite right, but the cans were hot when they came out soshe figured everything would be okay.Several months after their weekend of canning, the ladies invited the entire family over for Thanksgiving dinner. The meal consisted ofturkey, ham, chicken, macaroni and cheese, rolls, spinach salad, tomatoes, corn, lima beans, green beans, and okra. All of thevegetables were the ones they had previously canned from their garden. For dessert, they had pecan pie and vanilla ice cream. Thenext day, while most of the family was out shopping, four of the family members were home with blurred vision, dry mouth, and muscleweakness. Mary called the family physician, Dr. Franklin, who told her to take the sick individuals to the emergency room, and he wouldmeet them there. Upon arrival at the ER, Dr. Franklin asked what the family members had eaten for the meals before they developedthe symptoms. The common foods that all of them ate were the chicken, the ham, the tomatoes, the green beans, and the spinachsalad. The doctor determined that the family was suffering from botulism food poisoning. In the United States, foodborne botulismhappens in 15% of cases each year, frequently from foods with a low acidity. He was suspicious of the green beans and tomatoes, eventhough tomatoes are highly acidic. Dr. Franklin also said that using proper methods of microbial control could have prevented theirillness.
Which of the following is an example of microbial control?
a. Sue washes off the vegetables before serving them in a meal.
b. Mary warms food up in a microwave before putting it on the table.
c. Sue uses bleach to clean the kitchen counters.
d. Mary places leftovers in the refrigerator after the meal.
Answer:
Option a (Sue........meal) would be the correct answer. Below however is the explanation offered.
Explanation:
Prevention: Clostridium botulinum seems to be a type of bacteria that is prevalent in soils and seems to be present in raw water. As either a resistant spore, this could live in some of these conditions. And when no indications of food contamination become visible, the spores of the whole bacterium would be hard but instead active however after heating. Boil home-processed foods for at least 10 min while feeding. To destroy the activated spores, ten minutes of warming will destroy the toxins. During at least a few thirty minutes, 120 ° of warming can indeed be achieved with the aid of gravity. Discard any containers that appear broken and are therefore bulging, dripping, smelling.Boiling will kill the bacterial spores as well as the toxins it creates. In house soil, bacteria may also be present.All other three methods are not connected to the case provided. So, the solution here is just the right one.

Life could not exist on Earth without trees because they produce most of the oxygen that humans and wildlife breathe. Trees absorb carbon dioxide from the atmosphere and release oxygen using the process of photosynthesis. There would also be no rain without trees since trees absorb water from the soil and release it through evapotranspiration. Water vapor released through evapotranspiration is the major mechanism by which air is remoistened. Forests act as giant air filters for the world. Trees purify the air by absorbing pollutants such as sulfur dioxide and nitrogen dioxide, reducing pollution. Trees also help prevent topsoil erosion because they break the force of wind and rain on soil, their roots bind the soil, and their decayed, falling leaves are absorbed by the earth and enrich the soil. Trees conserve rainwater and reduce water runoff and sediment deposit after storms.Additionally, trees provide a supply of lumber, seeds, and fruit. Further, dead trees that fall and get
there are six classes of nutrients that must be considered when planning your diet: water, proteins, carbohydrates, fats, vitamins, and minerals. most foods or ingredients include more than one of the six basic nutrients. for example, although most people usually think of corn as containing carbohydrates, it is important to remember that a kernel of corn contains all six basic nutrients.
Match the words to the appropriate blanks in the sentences.
_______nutrients be synthesized by the human body, but are required for optimal functioning. Therefore. they must be Obtained from food. Omega-3 fatty acids are prime examples.
You consume macronutrients (water. proteins, carbohydrates, and fats) in large quantities as opposed to _________ which you consume in small quantities
_________ can develop very quickly when exercising in hot/humid weather conditions.
_________are also called 'body builders" due to their function within the body________ are the building blocks of proteins.
1. glucose and fructose
2. essential
3. incomplete
4. proteins
5. fat soluble
6. plant
7. amino acids
8.saturated fats
9. micronutrients
10. dehydration
Answer:
Essential nutrients cannot be synthesized by the human body but are required for optimal functioning. Therefore. They must be obtained from food. Omega-3 fatty acids are prime examples.
You consume macronutrients (water. proteins, carbohydrates, and fats) in large quantities as opposed to micronutrients which you consume in small quantities
Dehydration can develop very quickly when exercising in hot/humid weather conditions.
Proteins are also called 'bodybuilders" due to their function within the body. Amino acids are the building blocks of proteins.
Explanation:
Essential nutrients are those nutrients that are required for the proper functioning of the body but cannot be synthesized by the body. They are obtained from external sources such as vegetables or synthesized artificially in the laboratories. Micronutrients as the name implies are taken in small amounts. Examples are the different types of vitamins.
Dehydration occurs when a person loses a good amount of water through sweating or urination. It can easily occur while exercising in hot weather conditions. Proteins repair the cells in our body and are, therefore, rightfully referred to as bodybuilders. Amino acids form proteins.
