Based on the total annual income from simple interest, $2000 was invested in Account 1 while $3000 was invested in Account 2.
What is simple interest?Simple interest the amount of interest charged on a sum at a given rate and for a given period of time.
Simple interest = Principal × rate × timeIn simple interest, the principal amount is always the same.
Given that the principal is $5000
This amount was invested into two account at the following rates:
Account 1 at 4.5% interest rate
Account 2 at 6% interest rate
Total income from simple interest = $250
Let amount invested in Account 1 be y; amount invested in Account 2 will be 5000 - y
Interest on Account 1 = y × 4.5% × 1 = 0.045y
Interest on Account 2 = (5000 - y) × 6% × 1 = 300 - 0
06y
0.045 y - 0.06y + 300 = 270
-0.015 y = -30
y = 2000
5000 - y = 3000
Therefore, $2000 was invested in Account 1 while $3000 was invested in Account 2.

One person consumes the equivalent of five cows per year. Five cows consume a total of 39 million Calories of vegetation per year. One person only needs one million Calories a year to survive. Which statement best describes the efficiency of energy transfer in this scenario?
It is very efficient because the person can eat less.
It is inefficient because less energy is needed at the top.
It is very efficient because most energy is made by producers
Only a portion of energy from vegetation makes it to a person.
Answer:
It is very efficient because the person can eat less.
Explanation:
the common knowledge answer
Only a portion of energy from vegetation makes it to a person. The correct option is D.
What is energy efficiency?The definition of energy efficiency is the use of less energy to carry out a task or achieve a goal.
Ecological efficiencies at each trophic link determine the food chain efficiency (FCE), which is calculated as the percentage of energy fixed by primary producers that is transmitted to the top trophic level.
The energy supply accessible to trophic level N+1 divided by the energy used by trophic level N is the definition of ecological efficiency.
Only a percentage of the energy from vegetation makes it to a person, which best sums up the efficiency of energy transmission in this situation.
Thus, the correct option is D.

Answer:you to eat to get energy
Explanation:
The main reason you need to eat is to get energy. Food is your body's only supply of energy. However, this energy must be converted from the apple (or any other food you eat) into an energy source that your body can use.

HELP, define genetic engineering and Describe how DNA is modified for use in genetic engineering.
Answer:
Genetic engineering is deliberate modification of genome to gain desired traits.
The main steps of genetic engineering:
Restriction enzymes are used to isolate the required gene leaving it with sticky ends. Sticky ends are a short section of unpaired bases A vector, which is usually a bacterial plasmid or a virus, is cut by the same restriction enzyme leaving it with corresponding sticky ends. The vector and the isolated gene are joined together by ligase enzyme. The vector inserts the gene into required cells. The genes are transferred to animal, plant or microorganism cells, during early development, which allows them to develop with the desired characteristics.

Advantages to community:
1. Geothermal energy is a renewable energy resource because heat extracted is very small compared to the Earth's heat content.
2. It is reliable and constant source of energy as it can extracted all through the year despite changing weather patterns.
3. Geothermal energy is widely available and it creates new job opportunity.
Disadvantages:
1. Cost of installation of geothermal heat pumps are high.
2. This power plants plants are suitable to particular region and they are far from cities.
Advantage to the environment:
1. It is echo friendly and non-polluting from production to use.
2. Geothermal plants occupy a less space, no-mining or no transportation is require and thus protects the natural environment.
3. There is no wastage or by -products.
Disadvantage:
1. This power plants may trigger earthquakes.
2. Power plant uses lot of water in its processes.

Which of the following illustrates the principle of induction in invertebrates?
A. In an embryo, the presence of a notochord beneath the ectoderm results in the formation of a neural tube.
B. A neuron synapses with another neuron via a neurotransmitter.
C. Eye muscles constrict in response to light.
D. Secretion of TSH stimulates the secretion of thyroxine.
E. The maternal parent induces spontaneous expression of recessive genes.
Answer:
A
Explanation:
A
How does the ectoderm that will make up the future eye know to develop into an eye? The cells are "told" to develop into an eye because the nearby retina releases chemical signals that direct the development of the cells. This process is called induction. Choice A depicts a similar situation. The notocord releases chemical signals that tell the overlying ectoderm that it is time for it to become the neural tube. None of the other choices depict the process of induction.
