Mr Mwape and his wife are both heterozygous tall and brown and have 3 children who are tall and brown and one child who is short and dark what explanation can you give mr Mwape to understand variation in his children?
We can explain Mr Mwape that variation in his children through Mendel’s law.
Reason why three children tall and brown one of MR Mwape was short and dark is: -
• Skin color and height is controlled by a lot of genes and every human gets one set of genes from their mother and the other set of genes from their father.
• Now imagine these genes are denoted as ‘T’ for tall and ‘B’ for brown and ‘t’ for short ‘b’ brown. We can assume that MR Mwape and his wife having genotype TtBb.
• During the process of gene segregation and assortment, the majority percentage of children got the heterogenous dominant genotype, which is ‘TtBb’, overlapping the effect of gene ‘t’ and ‘b’. While another child got a homogenous recessive genotype ‘ttbb’ from both the parents, hence the genotype is prominently shown in the fourth child and not in other as gene 't' and 'b' were dominated by genes 'T' and 'B'.

Both solar energy and fossil fuels can be used to produce electricity. What is
an advantage of using solar energy over fossil fuels?
A. Electricity made from solar energy can be difficult to transport.
B. Solar energy is distributed unevenly on Earth's surface.
C. Solar technology usually costs more than fossil fuel technology.
D. Solar energy is a renewable resource.
Solar energy is a renewable form of energy and is therefore more advantageous to use it over the fossil fuels in order to produce electricity.
The correct option is option D.
Solar energy is basically a renewable source of energy as the Sun will always continue to produce energy which makes it both a sustainable as well as a reliable source of energy when compared to fossil fuels which are non-renewable and will therefore run out with time.
Solar energy is also a very clean form of energy as it does not cause pollution unlike the fossil fuels and therefore it is more advantageous to use solar energy for producing electricity.

Answer: I live in a very humid climate in the coastal Southeastern United States. Our water comes from three sources – groundwater, surface water, and a desalination plant that is almost ready to come on line. At the moment, around 65 percent of our water is sourced from groundwater, with the other 35 percent coming from surface water. The groundwater is sourced from our natural aquifer that stores the billions of gallons of water that seep down through the soil. The surface water is drawn from local rivers. Even with high humidity, evaporation of water from reservoirs is a problem, and we have been operating under water restrictions (you can only water your yard once a week) for several years. The arrival of the desalination plant will add up to 25 million gallons of drinking water to our region every day to help meet the demand of over 150 million gallons per day.

How can ecological factor influence in pond ecosystem?
Answer:
Many important components of animal behavior, growth, and reproduction are tightly linked to environmental conditions, particularly for ectothermic freshwater organisms. For amphibian species, factors such as temperature and rainfall can be physiologically limiting and alter activity levels. The effects of environmental conditions on terrestrial amphibian movement have been well characterized, but less is known about the importance of these factors in aquatic habitats. Here we investigate the impact of temperature and rainfall on the activity of a pond-dwelling amphibian using capture patterns of aquatic adult red-spotted newts (Notophthalmus viridescens). Data on newt captures, air temperature, and rainfall were collected for 6 years (2009, 2011, 2013–2016) during the winter breeding season at a wetland in the Piedmont region of North Carolina, USA. In 2016, we collected more detailed data on the size and sex of captured newts, as well as recording water temperature.

Which is a true statement about air quality? Good air quality is shown by high levels of smog. O Bacteria is a major cause of poor alr quality. O Water treatment plants measure the air quality. The EPA measures air pollution levels daily.
Option (d) EPA measures air quality daily is correct: -
• Option (a) incorrect because smog occurs in air with high air pollution. It usually occurs in colder weather condition and is a mixture of smoke and fog (water molecules in air).
• Option (b) is incorrect because majority of air pollution is due to carbon emission and particulate material evolved due to it and not bacteria. Some bacteria even fix air pollution through the process of bioremediation.
• Option (c) is incorrect as water treatment plants are primarily used to treat waste water so that it can be discharged in larger water bodies.
• Option (d) is correct because EPA (Environment Protection Agency) calculates Air Quality Index (AQI) for five major pollutants which are; ozone, particulate matter, carbon monoxide, sulphur dioxide and nitrogen oxide. This is done to safeguard public health and take preventive measures.
