Answer: laboratory experiments
Explanation:
Exponential growth can be define as the increase in per capita growth of the population when the resources available are surplus. A limiting factor is the one which is capable of limiting the growth, abundance and distribution of population of species. Predator populations, habitat conditions and food resources all are examples of limiting factors which can limit the growth of population exponentially.
Laboratory experiments cannot be consider as limiting factor hence, are not responsible for limiting the exponential growth.
Use at least two examples to explain how technology has greatly increased food production in the world.
Advances in science and technology have contributed significantly to the production of food in the world. Production capacity in agriculture has grown by 2.5 to 3 times over the past 50 years. This allowed, at a global level, that the increase in food production accompany the population increase.
An example of how technology has contributed to the increase in food production in the world is Transgenia. Through transgenic seeds, it was possible to plant crops that are more resistant to pests and to periods of drought, in addition, the transgenic crop has created crops with greater productivity. This has contributed greatly to the increase in food production.
Another example is the use of increasingly technological agricultural machinery, which can carry out agricultural work faster and more efficiently, reducing agricultural losses and contributing to increased production.

Research shows that Mount Everest grows an average of 4 millimeters each year. How many years will it take to grow 720 millimeters
Answer:
180 years.
Explanation:
To calculate this we will need to make a very simple calculation, called the "rule of three", which is a calculation used to find the ratio of three factors.
If we look at the question above, we will see that Mount Everest grows 4 millimeters per year (so in our calculation we will use the ratio 4 = 1), but we don't know how many years ago Mount Everest will grow 720 millimeters (so in our calculation we will use the proportion 720= x).
This way we will have the calculation:
4 = 1
720 = X
From this, we will imagine a diagonal line and multiply the values at the end of each line. This way we will have:
4 x X = 1x 720
As a result we will have:
4X = 720
Now we will move all numbers to one side and all letters to the other side. Since the number 4 is multiplying the letter X, it will move to the other side dividing the 720. So we have:
X = 720/4.
As a result we will have:
x = 180 years.

Phospholipid tails are hydrophilic and are attracted to water true or false
Answer:
False.
Explanation:
Phospholipid tails are hydrophobic, which means that they are repelled by water.
Thus, each phospholipid contains a hydrophobic portion (tails) - represented by fatty acids - and a hydrophilic portion (head) - corresponding to the phosphate group and its associated molecules. A notable fact is that, when placed in water, the phospholipid molecules can assume the shape of a sphere, known as micelle: the polar, hydrophilic portions are distributed in the periphery, while the hydrophobic tails, the tails, are in the inside the micelles away from the water.
Phospholipids are amphipatic molecules composing cell membranes. Their heads are hydrophilic, while their tails are hydrophobic. The statement phospholipid tails are hydrophilic and are attracted to water is false.
What are phospholipids?
Phospholipids are amphipathic molecules arranged in cell membranes. They have
hydrophilic heads facing the exterior and the interior of the cellshydrophobic tails that arrange against each other in the interlayer space.In the membrane, phospholipids can easily change places with other lipids by lateral diffusion in the same layer.
They can also diffuse transversally to the other layer but not as easily as lateral diffusion.
There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.
The statement Phospholipid tails are hydrophilic and are attracted to water is false. Tails are hydrophobic and reject water.

Explanation:
What is the maximum magnification of a compound light microscope? 500x 1,000x 2,500x 5,000x
Answer:
Option B, 1000 X
Explanation:
The simple formula to find the magnification strength of compound light microscope is to multiply the magnification power of eyepiece lens by the objective lens power.
For example – if an eyepiece has power of10x and objective lens has power of 20x , then the highest magnification could be 10 X 20 i.e 200
However, the maximum magnification power of a lens is 1000x
Thus, option B is correct
Are the metabolic rates of the three mammals comparable when based on square meters of body surface area
Final answer:
The metabolic rates of mammals are not directly comparable based on square meters of body surface area. Smaller mammals have higher metabolic rates per body weight because of their greater surface area-to-volume ratio.
Explanation:
The metabolic rates of mammals are not directly comparable when based on square meters of body surface area. Smaller mammals, such as mice, have higher metabolic rates per body weight compared to larger mammals, such as elephants. This is because smaller animals have a greater surface area-to-volume ratio, leading to more heat loss and therefore requiring more energy to maintain a constant body temperature.

Can a dog wag its tail without the tail in turn "wagging the dog"? (consider a dog with a relatively massive tail.)
Final answer:
A dog wags its tail intentionally through muscle control; however, in the case of a very heavy tail, this could affect the dog's balance. To describe a dog to someone without sight, use sensory details beyond visuals. Lastly, although dogs communicate through barks and tail wags, this is not equivalent to human language.
Explanation:
The question appears to be asking whether the physical act of tail wagging in a dog with a particularly large or "massive" tail can cause the dog's body to move involuntarily as a result of tail movement (often humorously referred to as "the tail wagging the dog"). From a biological standpoint, a dog controls its tail via muscles at the base of the tail, meaning the dog intentionally wags its tail but does not typically move its entire body as a reflex of tail wagging. However, in practical terms, if the tail was significantly heavy, it could influence the dog's balance or body position, especially in a smaller dog or a dog with an abnormally large tail.
When explaining the experience of a dog to someone without sight, it is important to focus on sensory descriptions beyond the visual. Describing the dog's firm body, various textures of the fur, the swishing sound of a wagging tail, and the warmth of the animal can help in painting a more tangible picture of a dog's physical characteristics and presence.
As for animal communication, it's important to note that while animals do communicate with each other, their communication methods are not equivalent to human language. A dog's bark or tail wag is a form of non-verbal communication that conveys excitement, curiosity, or other emotions, but it doesn't translate directly to human spoken words.

What is meiosis?Cell cycles has been argued so far in this branch development in diploid daughter cells with identical genetic complements. Meiosis, in contrast, is a specialized kind of cell cycle that disrate the chromosome number by half, the outcome in the production of haploid daughter cells, throughout meiosis I, homologous chromosomes first pair with one another and then segregate into dissimilar daughter cells.
Egg and sperm cells have just 23 chromosomes each. That's half as many chromosomes as regular cells. Through the process of fertilization, egg and sperm join to make a cell with 46 chromosomes (23 pairs), called a zygote. For each chromosome pair, one homologous chromosome came from each parent.
During sexual reproduction two sex cells fuse to make a fertilized cell with one set of chromosomes the true about number of chromosomes is that the Egg and sperm cells have just 23 chromosomes each.
