Which factor is primarily responsible for location A
having a lower average yearly temperature
than location B?
(1) nearness to a large body of water
(2) elevation
(3) latitude
(4) prevailing winds
Answer:
Nearness to a large body of water
Explanation:
Nearness to a large body of water is primarily responsible for location A having a lower average yearly temperature than location B. Hence, option A is correct.
What are the factors affecting the temperature of an area?The horizontal distribution of temperatures refers to how the Earth's surface's temperatures are distributed throughout latitude. Isotherms display the horizontal distribution of temperature on Earth. Isotherms are line intersections where the temperatures are the same. Analysis of the isotherm map reveals that the temperature is unevenly distributed along its horizontal axis.
The troposphere's temperature drops as you ascend in height, although the rate at which it drops varies depending on the season.
Elevation, latitude, prevailing winds, ocean currents, and distance from the sea are some factors that affect the temperature of an area.

Write a sentence explaining the relationship among Gene, chromosome, and nucleus.
Answer: Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

5. How are matter and energy cycled between plants and animals? How can you
apply this information to help you determine what is going wrong in the
greenhouse?
Answer:
Plants and animals get their energy in different ways by creating photosynthesis in able to obtain energy, while animals get energy from consuming waste and other organisms.The food of almost any kind of animal can be traced back to plants. ... Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. Organisms obtain gases and water from the environment and release waste matter (gas, liquid, or solid) back into the environment.

Write a paragraph explaining how energy flows through an ecosystem.
Be sure to use the following terms:
Energy Pyramid Sun
Trophic Level Producer,
Primary Consumer Decomposer
Secondary Consumer Tertiary Consumer.
Answer:
The living organisms of an ecosystem are related through food chains, which gives rise to trophic levels in an ecosystem. There is a flow of energy from one trophic level to the other in a food chain. Producers bring energy from the sun into the community. Primary consumers eat the producers, which makes them herbivores in most communities. Secondary consumers eat the primary consumers, which makes them carnivores. Tertiary consumers eat the secondary consumers. A final link in the food chain are decomposers, which break down the organic matter of the tertiary consumers (or whichever consumer is at the top of the chain) and release nutrients into the soil. Thus, there is flow of energy from Sun ------> Producer ------> Herbivore -------> Carnivore ------> Decomposers.
How energy flows through an ecosystem is summarized below.
Energy flows through an ecosystem in the following order:
Sun ----> Producer ---> Primary consumer ---> Secondary consumer ---> Tertiary consumer ---> Decomposer.
Some of the energy from the sun is fixed by the producer through a process known as photosynthesis. The producers are usually green plants and photosynthetic bacteria.Primary consumers feed directly on the producers.Secondary consumers feed on the primary consumers.Tertiary consumers feed on the secondary consumers.The decomposers feed on the remains of the tertiary consumers.As the energy flows from producer to the different consumers, and to the decomposer, only about 10% of the energy available in each trophic level move to the next with the rest being lost to heat.
Hence, an energy pyramid is created as we move from the lower trophic level to higher trophic levels.

Is Salmonella maintaining? Why or why not? Plz help
Answer and explanation:
No, because most people are infected with salmonella by eating foods that have been contaminated by the s-word. Since our society is much more industrialized, we are cleaner when it comes to making food. Salmonella is mostly found in dirtier countries such as third world countries. Obviously, other food-borne illnesses are out there, but salmonella is not as common anymore, since we are improving.
