Despite the rampant depletion of trees in the natural forest in Ghana,it is still worth using wood as the main construction.Disscuss
Answer:
Hope this helps!
Explanation:
Forest resources support livelihood of people in jurisdictions in which forest is located. However, the forest size is gradually depleting continuously. The lack of information about the specific agents and forces of forest depletion is worrying. This is due to the inter-generational and intra-generational equity notions that affect mankind. As such, there is the need to maintain such resources on a non-declining value basis so as to maintain human welfare over time. Thus, the objective of this study is to empirically examine the determinants of forest depletion in Ghana over the 1970-2012 period in Ghana. This study employs multiple regression concepts to examine the effects of the determinants on forest depletion. The findings of the study indicate that gold extraction for export, population growth and logging increase the rate of forest depletion for the study period. More significantly, population growth reflected in settlement expansion, agriculture purposes, increased use of fuel wood, etc have greater effect on forest loss in Ghana. This suggests that, protection of the forest is necessary and sufficient condition for economic growth. As a result of these, both government and policy-makers need to safeguard the forest estate, by increasing afforestation schemes and also using part of the returns from gold exports to regenerate the forest.

List and explain the characteristics of living things
Answer:
Life process
Movement
Respiration
Sensitivity
Growth
Reproduction
reason:
Life process
Explanation
Earthworms
Movement
All living things move in some way. This may be obvious, such as animals that are able to walk, or less obvious, such as plants that have parts that move to track the movement of the sun.
Earthworms use circular and longitudinal muscles to move through soil or along surfaces.
Respiration
Respiration is a chemical reaction that happens within cells to release energy from food.
The food that earthworms eat supplies their body with energy-rich molecules such as glucose. On entering the cells of their body, these molecules are broken down in a series of steps to release energy to be used by the body, producing carbon dioxide and water as waste products.
Sensitivity
The ability to detect changes in the surrounding environment.
Earthworms have light-sensitive cells scattered in their outer skin. Their skin cells are also sensitive to touch and chemicals.
Growth
All living things grow.
Earthworms hatch from eggs and can grow up to a metre or more in length! Some earthworms are also able to regrow small parts of their body that have been lost or injured.
Reproduction
The ability to reproduce and pass genetic information onto their offspring.
Earthworms have both sperm and eggs within their bodies (they are hermaphrodites) but they cannot self-fertilise and need to mate with another individual. After mating, a cocoon containing the fertilised eggs is deposited in the soil.
Excretion
Getting rid of waste.
Earthworms excrete waste from their anus – the last segment of their body.
Nutrition
The intake and use of nutrients. This occurs in very different ways in different kinds of living things.
Earthworm nutrition comes from a variety of sources, depending on their species. Food types include manure, compost, plant material, fungi, microorganisms and decaying animals. They take in food through their mouths.

A population of rabbits lives in a grassy field that is lush and green in summer and covered in snow in winter. At the start of the summer, 75% of the population are white rabbits, and the remaining 25% of the population are brown rabbits. In rabbits, white (W) is dominant over brown (w). During the summer, the field where they live experiences a drought. The summer drought lasts for two years, through many generations of rabbits.
Which prediction BEST estimates the expected percent of white and brown rabbits in the population at the end of the drought?
Answer:
The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
Explanation:
hope this helps!
The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
What are the limiting factors of the rabbit population?Until a limiting factor, such as low reproduction, food scarcity, predation, disease, and/or weather conditions restrict populations, the population tends to grow.
Some density-dependent limiting factors are the spread of pathogens, competition for nesting locations, the destruction of habitat, increase in the population of predators. Several predators, including raptors and coyotes, use rabbits as food, but in urban and suburban areas, cats and dogs pose the biggest threat. Some abiotic limiting factors are drought, flood, earthquake, and all types of natural disasters.
Thus, the rabbit population will consist of 35% white rabbits and 65% brown rabbits.

Calculate the map distance between B and C.
Answer:
Map distance = Genetic distance, GD = 3.9 MU ≅ 4 MU
Explanation:
The more separated two genes are, the more chances of recombination there will be. The closer they are, the fewer chances of recombination there will be. Two genes that are very close will have a few recombination events and are strongly bounded.
To analyze the recombination frequency, we have to know that:
1% of recombination = 1 map unit = 1centi Morgan = 1,000,000 base pairs. And that the maximum recombination frequency is always 50%.The map unit is the distance between the pair of genes for which every 100 meiotic products one of them results in a recombinant one.
Knowing that the genes are linked, we can calculate genetic distances between them. First, we need to identify the genotypes of the parental gametes with the ones of the recombinants. We can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the recombinants are the less frequent. So:
Parentals:
black, curved 337yellow, straight 364Recombinants:
Black, straight 17yellow, curved 12To calculate the recombination frequency we will make use of the next formula: P = Recombinant number / Total of individuals.
P = Recombinant number / Total of individuals.
P = 17 + 12 / 337 + 364 + 17 + 12
P = 29 / 730
P = 0.039
The genetic distance (GD) will result from multiplying that recombination frequency (P) by 100 and expressing it in map units (MU).
GD = P x 100
GD = 0.039 x 100
GD = 3.9 MU ≅ 4 MU

Explanation:
Cape Town, South Africa has a significant water shortage. The amount of water available is not sufficient to support the current human population of the city.
Which three factors most likely contributed to the growing water shortage?
- Strict water management policies.
- Naturally-occurring drought conditions.
- Underdeveloped alternative and supplemental water sources.
- Migrations of residents out of the city and into surrounding areas.
- Higher demand for water than natural reservoirs accumulate each year.
Explanation:
The city's water supply shortage seems to be the result of a combination of physical, social, and political factors. Well below-average rainfall patterns, the increasing unpredictability of weather conditions due to anthropogenic climate change impacts, population growth, and government mismanagement have produced one of the worst urban water crises in recent memory.
here is the reason your explanation from the water shortage now just figure out what the factors are in your answers I would say it's naturally occurring drought conditions because it says on here well below average rainfall patterns and climate change
Water shortage can occur as a result of mismanagement practices by humans or as a result of natural occurrences such as droughts.
What is water shortage?Water shortage refers to a situation in which there is not enough water to meet the daily water needs of the human, animal and plant population in a particular area.
The water shortage issue in Cape Town, South Africa could have been as a result of:
Naturally-occurring drought conditionsUnderdeveloped alternative and supplemental water sourcesHigher demand for water than natural reservoirs accumulate each yearTherefore, water shortage can occur as a result of mismanagement practices by humans or as a result of natural occurrences such as droughts.
