Without land regulations to protect rainforests, and continues to be destroyed using slash and burn methods Which environmental impact of rainforest deforestation makes rainforest species less resilient to
change?
Increased fire and drought
Increased pollution
Displaced inbes
Habitat fragmentation
Answer:
Increased pollution is your answer!
Explanation:
Increased pollution is your answer because:
1. ⇒ Burning of mostly anything creats, and all the materials in the forest are one of those materials that will create smoke. And smoke is made out of carbon dioxide, and other poisonous gases that are very bad for our atmosphere.
2. ⇒ The damage from the fire will also cause a lot of damage to the trees and plants. That is very bad because trees are very important for our environment, in their leaves, they have a chemical called chlorophyll, this chlorophyll absorbs sunlight and turns it into oxygen. Not only sunlight is needed, there is also, water, nutrients needed.

relationship between enzymes and macromolecules
Answer:
Each macromolecule is broken down by a specific enzyme. For instance, carbohydrates are broken down by amylase, sucrase, lactase, or maltase. Proteins are broken down by the enzymes pepsin and peptidase, and by hydrochloric acid. ... Breakdown of these macromolecules provides energy for cellular activities.

in what generation does this population reach its carrying capacity
Answer:
The logistic population growth happens as the growth rate declines as the population exceeds the carrying power. The highest number of people in a community that the ecosystem can sustain is carrying capacity.
Explanation:
A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.
What is carrying capacity?The carrying capacity of a population is the maximum number of individuals that can be supported by a particular environment over a given time period. A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.
For example, if a population of animals is introduced to a new habitat with abundant resources, it may be able to grow rapidly and reach its carrying capacity relatively quickly. On the other hand, if the population is facing competition from other species or is subjected to predation or other limiting factors, it may take longer for the population to reach its carrying capacity.
It's important to note that the carrying capacity of a population is not a fixed value, and it can change over time due to changes in the environment or the population's own characteristics. For example, if the population grows to a size that exceeds the carrying capacity of its environment, it may begin to experience negative impacts such as resource depletion, disease outbreaks, or other factors that can reduce its size and bring it back down to the carrying capacity.

Compare 41 Calories to 410 kcal (1 kcal = 1,000 calories). (1 point)
O 41 Calories is greater than 410 kcal
O 41 Calories is equal to 410 kcal
41 Calories is less than 410 kcal
It is not possible to compare these two values
From the calculation, we can deduce that 41 Calories is less than 410 kcal.
Given the following data:
Energy in calories = 41 CaloriesEnergy in kcal = 410 kcalTo compare 41 Calories to 410 kcal, we would simply convert the given values to the same base values:
Hence, we would make Calories the base value by converting the value in kcal to Calories as follows:
Conversion:
1000 Calories = 1 kcal
41 Calories = X kcal
Cross-multiplying, we have:
[tex]1000X =41\\\\X=\frac{41}{1000}[/tex]
X = 0.041 kcal.
From the calculation, we can deduce that 41 Calories is less than 410 kcal.

what are the similarities between this activity and actual mitosis
The DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.
What is mitosis?Mitosis is defined as the cell-division process in which the chromosomes multiply and are equally distributed between the two daughter cells. Prophase, Prometaphase, Metaphase, Anaphase, and Telophase are the five stages that make up mitosis. Meiosis is defined as a process by which a single cell undergoes two divisions, resulting in four cells with half the original genetic material.
Cell division occurs during meiosis as well as mitosis. The M-phase of the cell cycle is where both processes take place. The prophase, metaphase, anaphase, and telophase stages are typical for both cycles. DNA synthesis occurs during both cycles. A common goal of meiosis and mitosis is the division of the nucleus and its DNA into two daughter cells.
Thus, the DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.

Obesity is a digestive system issue for which of the following age groups?
Answer:
d. All of the above
Explanation: is correct
Section 3: For at least one of the sub-problems, propose two solutions based on the information from the lesson and your additional research. In the rationale column, explain how your solution restores the stability and biodiversity of your selected ecosystem.
Removal of invasive species and growing more vegetation can restore the stability and biodiversity of ecosystem.
These two solutions restores the stability and biodiversity of the selected ecosystem because invasive species can capture more resources as compared to local species which leads to the extinction of local species.
While on the other hand, growing more vegetation provides more food to the organisms which ultimately increases the biodiversity of the ecosystem so we can conclude that removal of invasive species and growing more vegetation are the solutions to bring ecosystem in a stable condition.

Observe the cut ends of the flatworms using the hand lens or the dissection microscope immediately after cutting.
What do you see?
Are there distinct differences between the two ends?
Observe the cut ends of the flatworms over a period of several days. Do the flatworm halves continue to exhibit the same degree of difference that was seen right after they were cut in two?
What kinds of changes occur in the flatworms as they recover from having been cut in two?
The above question requires a personal answer about your experience with cutting flatworms. I can't tell you what you saw in this cut, but I'll show you what happens when it occurs.
First of all, you must understand that flatworms are worms with a great capacity for cell regeneration even if several pieces have been cut.
In this case, when a flatworm is cut in half, we can see the following events happen:
At the moment of cutting, the two ends of the flatworm body are equally shaped and are straight ends, without deformations.The ends will not be different if the cut is done accurately, but it may differ slightly.After several days, the ends will present some deformations and will lose the straight shape caused by the blade.Deformations are extremely similar and change similarly.When recovering from the cuts, each side of the flatworm body formed a new flatworm and they are no different, they are the same and they are completely recovered.This is because the cellular regeneration of flatworms is very fast and allows any part of the flatworm's body to create exactly the same beings, as they have the same genetic makeup.

active transport moves mineral ions into root hair cells through cell membrane proteins. Explain how protein molecules move ions across a membrane during this process. (3marks)
Explanation:
Small and nonpolar (hydrophobic) molecules can freely pass through the membrane, but charged ions and large molecules such as proteins and sugars are barred passage.
Nonpolar and small polar molecules can pass through the cell membrane, so they diffuse across it in response to concentration gradients.
What does it mean when we say that replication is a Semi-Conservative process?
Answer:
Semiconservative replication describes the mechanism of DNA replication in all known cells. ... This process is known as semi-conservative replication because two copies of the original DNA molecule are produced, each copy conserving (replicating) the information from one half of the original DNA molecule.
