Energy is an essential part of our daily lives, but the resources that power the Earth are being threatened. Imagine a world where people didn’t know how to generate energy. What do you think that world might be like? Describe your answer in 4-6 sentences.

Answer:

The correct answer is d) photosynthesis

Explanation:

Photosynthesis is the process by which plants transform inorganic matter from their external environment into organic matter that they will use for their growth and development. It basically consists of the production of sugars from C02 (carbon dioxide) in the air, minerals and water with the help of sunlight. In this reaction, oxygen molecules are released and carbohydrates are fixed in the plant. Plants absorb sunlight through a pigment called chlorophyll. Not only can plants fix CO2, so do certain bacteria and green algae. Photosynthesis is conditioned by internal plant factors and external or environmental factors.

Answer:

Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

Question:

Which of the following is an incorrect statement about the regulation of populations?

Answer:

b. Density-independent factors have an increasingly greater effect as a population's density increases.

Explanation:

A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.

Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.

Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.

Mathematically, the population change equation is given by the formula;

Population Change = (Natality - Mortality) + (Immigration - Emigration)

Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;

I. Density-independent factors.

II. Density-dependent factors.

Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.

Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.

Answer:

Heat Transfer

Explanation:

If Two chambers of water are poured side-by-side, the warmer water will mix the cooler layer because the water molcules in a jar of hot water are more spread out and the two jars seek a balance of tempature.

Answer:

In the case of seeing a ball and kicking it can be expressed in the actions of the nervous system as follows:

Part 1. Eyes see the ball and send signals with the help of sensory neurons that carry this message to the spinal cord.

PArt 2. The spinal cord processes the information and sends an "impulse" of kicking the ball that will transfer to motor neurons that transfer it to the brain and then muscles.

Sensory neurons --> spinal cord --> motor neurons --> brain---->leg muscles

Answer:

A. 17,100

Explanation:

The half life of carbon-14 is around 5,700 years. When the shell contains 50% of its original carbon-14, 5,700 years have passed. 25% means another 5,700 years have passed, meaning 11,400 years in total have passed. 12.5% means another 5,700 years have passed, meaning 17,100 years have passed in total.

Answer:

This question is not complete as it lacks options. However, it can be answered by giving the general differences between eukaryotic and prokaryotic transcription.

Explanation:

Eukaryotes are organisms that possess a membrane-bound nucleus that harbors their genetic material while prokaryotes are organisms that lack a membrane-bound nucleus.

Transcription is the process whereby a DNA template is used to produce an mRNA molecule. Below are the common differences in the transcription of eukaryotic and prokaryotic:

- Transcription in eukaryoric cell occurs in a NUCLEUS while transcription in prokaryotic cell takes place in a CYTOPLASM

- Transcription in eukaryotic cell requires proteins called TRANSCRIPTION FACTORS while transcription in prokaryotic cell does not require TRANSCRIPTION FACTORS.

- Transcription in eukaryotic cells occurs differently from translation while transcription in prokaryotic cells is coupled with translation i.e occur simultaneously.

Answer:

abiotic

Explanation:

abiotic - nonliving components of an ecosystem that can affect the living organisms.

Temperature is a nonliving component and it affects the organisms that live within a certain environment.

Therefore the answer is Abiotic

Reasons its not the other answers:

Biotic factors must be living things

Temperature is not a living thing therefore Biotic cannot be the answer

Same with living, temperature is not living therefore the answer cannot be living.

Temperature plays a huge role in an ecosystem therefore it is considered an important component and the answer cannot be unimportant.

Conserving water is important because it keeps water pure and clean while protecting the environment.

On worldwide basis domestic use uses least water.

a. industry: 19 percent of total water is used by industry.

b. agriculture: 70 percent of total water is used by agriculture.

c. hydroelectric power plants: 52 percent of water is used by hydroelectric power plant.

d. domestic use: 11 percent of total water is used by domestic use.

Thus we can conclude that the correct option is (d) that is domestic use.
