When designing an experiment, you come up with the question: How does the amount you talk to a plant help it grow? Which would be the best hypothesis
Answer:
The correct answer is - "If you increase the amount you talk to plants, then they will grow taller"
Explanation:
A hypothesis is a proposed or assumed explanation for the natural system or problem. It forms on the pre-existed or known data or knowledge. A good hypothesis should have the ability to relate to dependent and independent variables.
In this case, the best hypothesis would be "If you increase the amount you talk to plants, then they will grow taller" as it relates to the dependent and independent variables that are the growth of the plant and talking to the plant respectively.
The resting potential of resting neuron is caused by ________.A.A higher concentration of Na+ on the outside of the cell making it more positive outside.B.A higher concentration of Na+ on the inside of the cell making it more positive inside.C.A higher concentration of K+ on the outside of the cell making it more negative outside.D.A higher concentration of K+ on the inside of the cell making it more positive inside.
The resting potential of a resting neuron is caused by a higher concentration of Na+ on the outside of the cell making it more positive outside. So, it's A.
What do you mean by Resting potential?Resting potential may be defined as a condition of the imbalance of electrical charge that exists between the interior of electrically agitated neurons and their surroundings.
During resting potential, the passive efflux of K+ ion is more than the influx of Na+ ions. This imbalance makes the inside of the cell more negative as compared to the outside.
Therefore, the correct option for this question is A.

How does increasing in carbon dioxide affect photosynthesis?
Answer:
An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor.
VilliGroup of answer choicesgenerate movement of materials in the large intestine.are found throughout the gastrointestinal tract.contain both smooth and skeletal muscle fibers.increase surface area in the small intestine.All of the choices are correct
Answer: The VILLI (increase surface area in the small intestine).
Explanation:
Glucose, amino acids, fatty acids and glycerol, as well as , vitamins and minerals salts are absorbed in the small intestine. The walls of small intestine are specially adapted to carry out this function.
For efficient adsorption, a large surface area is necessary. The walls of small intestine have folds and furrows which serve to increase its surface area. These small finger-like projections are called the VILLI.
The inner surface layer or epithelium of each villus is thin; this allows the absorption of the end-products by either diffusion or active transport through it. There is a rich supply of blood vessels and lymphatic vessels containing blood and lymph respectively to carry away the absorbed food substances. In each villus( singular) , there is a blind lymphatic tube called a lacteal surrounded by a network of blood capillaries. The lymph in the lacteals transports carboxylic acids and glycerol which usually recombine to form fats again in the lacteals.

Why is it important to protect networks of ecosystems and habitats? Provide an example of a species in Alberta that would benefit from such protection and state why
Answer:
To maintain stability.
Explanation:
It is important to protect networks of ecosystems and habitats in order to get healthy and stable environment because the environment depends on ecosystems and habitats. If there is no ecosystem or habitat is destroyed then the whole ecosystem will greatly damaged that leads to the extinction of many animals that maintain stability in the environment. Swift fox (Vulpes velox) and Bison (Bison bison athabascae) are the two species that can be protected by protecting habitat and ecosystem.

what do the results suggest about ways that milkweed bug populations are limited in nature?
Answer:
Temperature.
Explanation:
Temperature was the only limiting factor that controls and limits the size of the population of milkweed bug in the nature because these milkweed bug are very sensitive to temperature. Little increase or decrease in temperature can cause adverse effect to the population f milkweed bug in that environment. Milkweed bugs need food, water, space, shelter and a mate in order to survive a well as increase in population of milkweed bug.
Have you ever had to estimate something for which there wasn't an exact answer? What was it? What tools did you use to
make your estimation? Discuss.
Answer: Yes, estimation of a population of plant species in a given area. The tool I used was a QUADRAT.
Explanation:
Plants in a small area are easy to count and their distribution is recorded on a map or scale diagram for the area. For larger areas, quadrats are used to obtain a fairly accurate estimate of the number and types of plants in those large areas.
The ESTIMATION of the population of plants can be done using a method called the quadrat sampling method. Here, a QUADRAT which is a rectangular or square frame(tool) made from thick wire, is thrown at random several times. On each landing, the area covered by if is observed. The type of species and their number within the quadrat are recorded. The average number of times each species appears is calculated and the most frequent or dominant species is then determined.
Some quadrats are specially made to mark off an area for the study of seasonal variations of plants. They are sturdier, larger and permanent and can thus serve their purpose through the seasons. These quadrats often have a mapping grid attached so that the flora within it can be mapped at regular intervals.

how many bacteria cells are produced at time T4 ?
Answer:
256.
Explanation:
If a bacterium divides once in every half an hour, it means it will double in half an hour. Hence a number of the bacterium after half an hour will be 1×2=2. After one hour the number of bacterium will be 2×2=4. Similarly, it one and a half hours it will be 4×2=8. In two hours it will be 8×2=16 in two and half hours, it will be 16×2=32. In three hours it will be 32×2=64. In three and half hours it will be 64×2=128. Hence, in 4 (four) hours the number of bacterium will be 128×2=256.
Answer:
256 bacteria cells are produced at time T4.

After a copper smelter begins operation, local downwind populations of plants begin to adapt to the resulting air pollution. Scientists document, for example, that the acid tolerance of several plant species has increased significantly in the polluted area. This is an example of
Answer:
Adaptation.
Explanation:
Adaptation occurs when the acid tolerance of several plant species has increased significantly in the polluted area. The main reason for this tolerance is the change in the genetic makeup or mutation occurs in the cell due to the exposure of DNA to the chemicals of the environment that cause pollution. The plant adopt the environment by producing certain chemicals that cancel the effects of pollutants and as a result, the plant survive.
