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.

Answer:
What vascular tissue transported these carbohydrates?
The xylem carries water and minerals from the roots, while the phloem carries out the massive transport of water and carbohydrates from the synthesis sites; that is, from the source organs to the dump or demand organs.
Explanation:
why is it important for plant's to store food?
Answer:
Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. ... When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
Answer:
It's important for plants to store food, as food is a source of nutrition, which is necessary for survival. Rather than just eating the food, storing it is a good way to ensure nutrients during droughts or other harsh conditions that make it hard to find food.
Explanation:
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.

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.
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.

How many genders are there?
Answer:
Nobody really knows how many genders there are.
Explanation:
It widely depends whether you're referring to actual genders or gender identity types. Even then, though, there is not a definite or limited amount of either. For more clarification about the differences...
Gender identity types include: transgender, nonbinary, agender, demigender, etc.
These are not genders because they don't specify what you identify as, they are simply stating that you do not identify with your sex at birth. Don't call these genders, because that would be putting agender and nonbinary people into a binary.
Actual genders include: two-spirit, pangender, polygender, etc.
These are GENDERS rather than gender identity types because they somewhat specify what you identify as.
To say that there are only two genders is incorrect, as gender is a social construct. That does not mean it's useless, it just means that it wasn't constructed correctly because nobody knows for a fact how many genders and gender identity types there are and we probably never will because it's based on one's individual feelings.
Answer:
alot. if you are talking about what you are born with (sex) then there is 3. which is male, female, and intersex. GENDER is completely different. there is too many that i can even say but you can be a girl, a boy, somewhere on the non-binary spectrum (non-binary, demigender, agender, gender fluid, ect), ect.

Mendel worked with pea plants, which are usually (cross-pollinating / self-pollinating). When he transferred pollen from one pea plant to another, he was (cross-pollinating / self-pollinating) the pea plants to (fertilize / segregate) the eggs and form embryos within a seed.
Answer:
1. self-pollinating
2. cross-pollinating
3. fertilize
Explanation:
Gregor Mendel was an Austrian monk regarded as the Father of Genetics due to his immense contribution to discovering the patterns of inheritance. During his lifetime, Mendel worked with garden pea plants (Pisium sativum). One of the notable reasons he worked with peas is their ability to SELF-POLLINATE.
However, Mendel transferred pollen from one pea plant to another in a process called CROSS-POLLINATION. In cross-pollination, the pollen from one plant is transferred to another plant in order to FERTILIZE the egg and form embryos within a seed.

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.
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.

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.
