Human activities and natural events can have a large effect on populations, biodiversity and ecosystem processes. How does the growth of the human population into rural areas affect the environmental quality of the native ecosystem?
Answers
Answer: human population growth in rural areas creates additional waste that is put back into the environment and lowers environmental quality.
Explanation:
Increase in human population in the rural areas leads to an increase in ;
Environmental pollution through indiscriminate waste disposal.As the human population grows the need to feed the growing population will increase as well as the amount of waste and all these will have a direct negative effect on the environment because the volume of waste in the environment will increase if not properly managed.
Human activities such as ; the use of chemicals for fishing and planting also pollutes the waters and land which are the vital part of the environment and the excessive burning of fossil fuels pollutes the atmosphere as well.
Hence we can conclude that Increase in human population leads to an increase in ; Environmental pollution through indiscriminate waste disposal.

¿una barra de acero en puente de un camino de la alta montaña tiene una longitud de 50 cm cuando se encuetra a 30 C. Calcular que longitud tendra cuando su temperatura descienda a la -25 C ?
Answers
Answer:
L = 50,033cm
Explanation:
Para saber cuál es la longitud final de la barra de acero cuando la temperatura desciende, solo debemos aplicar la siguiente formula:
L = L₀ (1 + ΔT)
Donde:
L = Longitud final L₀ = Longitud inicial = Coeficiente de dilatación lineal del acero = 1,2x10-5 ΔT = Cambio de temperatura T₁ – T₀Entonces, considerando los datos brindados en el ejercicio problema, sabemos que:
L₀ = 50cm T₀ = 30ºC T₁ = -25ºC ΔT = -25ºC-30ºC = 55ºCL = L₀ (1 + ΔT)
L = 50 cm x (1 + (1,2x10-5 x 55ºC))
L = 50 x (1 + 0,00066)
L = 50,033cm
A large amount of energy is needed to produce food. In all parts of the world, the energy used to process, distribute, and cook food is greater than the energy used to grow it. In the United States, it is estimated that every Calorie of food on our dinner tables has required 9 Calories of energy to get there. Half a Calorie accounts for the energy used on the farm. The other 8.5 Calories account for energy for processing, packaging, distribution, and cooking. In rural India, twice as much energy goes into cooking a kilogram of rice as was invested in producing it. Energy shortages, such as a shortage of wood for cooking, have caused environmental problems such as deforestation. In poor countries, cooking may require more energy than is used by transportation, heating, and all other uses for energy combined.
1. According to the passage, which of the following statements about food is true?
A. Most of the energy invested in food production goes into distributing the food.
B. More energy is used to grow food on the farm than is used to cook the food.
C. Most energy used to produce food goes into processing, distributing, and cooking the food.
D. In developing countries only, cooking food requires more energy than growing food does.
2. Which of the following points is not discussed in this passage?
A. Packaging is the least costly part of preparing food for sale to the customer.
B. It takes more energy to cook a kilogram of rice than to grow a kilogram of rice.
C. In some countries, cooking requires more energy than all other processes that use energy combined.

Explain the differences in the population growth patterns of the two Paramecium species. What does this tell you about how Paramecium aurelia uses available resources?
Answers
Answer:
The data in the question is missing, luckily, I found a matching data:
The following data is the results of a trial of paramecium growth over 16 days, the numbers going in order horizontally P. aurelia grown alone, cells/mL, P. caudatum grown alone, cells/mL, P. aurelia grown in mixed culture, cells/ mL, P caudatum grown in mixed culture, cells/mL.
Day O 1 1 1 1
Day 2 4 5 3 5
Day 4 27 15 16 9
Day 6 43 24 31 10
Day 8 54 28 38 7
Day 10 47 28 45 4
Day 12 48 28 46 1
Day 14 49 28 50 0
Day 16 49 28 47 0
Answer:
The pattern of growth tells us that individual Paramecium aurelia uses a smaller amount of resources for growth compared to P. caudatum, hence the greater number of species after culturing.
Explanation:
When bacteria species are cultured in an appropriate growth medium, they utilize the nutrient in such media for their growth, and the growth becomes exponential until there are not enough resources to sustain a continuous growth of the organism, then the growth pattern starts to show a decline which is seen in the P. caudatum species quickly because the organism use up more resources compared to the Paramecium aurelia species.

regulates which materials enter and leave the cell
Answers
Answer:
Regulates which materials enter and leave the cell.
Explanation:
I'm not 100% sure on this but I think cell membranes provide protection for the cell as well as regulating what enters and leaves the cell.
Cell membrane regulates which materials enter and leave the cell. So, the correct option is (D).
What is Cell membrane?Cell membrane is also called plasma membrane which is a semipermeable membrane made of lipids and proteins and found in all types of cells in humans, animals, plants, bacteria etc.
The cell membrane is the outermost boundary of animal cells. Cell membrane has many functions which are as follows:
Maintaining integrity within the cell.Providing support and preserving the shape of the cell.Through balancing endocytosis and exocytosis, it aids in cell growth regulation.Cell signaling and communication are also facilitated by cell membranes.Cell membrane functions as a selectively permeable membrane which enable only certain chemicals to enter the cell.
Thus, cell membrane regulates which materials enter and leave the cell. So, the correct option is (D).

Answers
Answer: TAACTG
Explanation: Remember the base pairing rules: cytosine with guanine and adenine with thymine. To compliment the given strand, you'd have to choose the base that would pair with each individual nucleotide.

DNA bases for the strand ATTGAC is TAACTG which is the complementary base pairing rule adenine pairs with thymine and cytosine pairs with guanine.
What is DNA base pairing?Thymine, adenine, guanine, and cytosine are the four nitrogenous bases found in DNA. Adenine and thymine are joined by two hydrogen bonds, whereas guanine and cytosine are joined by three hydrogen bonds.
Base pairing that is complementary is what this is to create a DNA molecule, the DNA sequence of a gene must be copied, bases for the strand ATTGAC is TAACTG.
RNA polymerases, which join nucleotides to create an RNA strand, carry out transcription (using a DNA strand as a template).
Therefore, DNA bases for the strand ATTGAC are TAACTG due to complementary base pairing.

How does hydrologic cycle depend on carbon,nitrogen,and phosphorus cycle
Answers
Explanation:
These biogeochemical cycles are important to the environment because this is how each respective chemical moves through the environment. Disrupting these cycles will impact organisms across the planet in multiple ways, as we rely on these cycles for our survival.
(To review each cycle, see these links: phosphorous cycle, nitrogen cycle, and the carbon cycle.)
Every living organism is made up of carbon, nitrogen, and phosphates. Nitrogen and carbon are found in amino acids which make up proteins. Phosphates make up DNA and ATP. Thus, the availability of these elements is of great importance to the existence of living things.
Human activities, such as the burning of fossil fuels, change the distribution of carbon throughout the cycle. The increased amount of carbon dioxide in the atmosphere is causing the planet to warm. The carbon cycle and the amount of carbon found in the atmosphere, the earth, and the oceans has acted as a sort of control for the longterm stability of temperatures across the planet.
