Answer:
Explanation:
This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer.

Nitrogen and phosphorus are referred to as macronutrients because ________. A. they are larger than other nutrients needed by plants B. they are needed by large organisms C. they are required in large amounts for organisms to survive D. they are needed to manufacture large biomolecules E. their cycles have larger reservoirs than those of micronutrients
Macronutrients are all substances that provide energy to the metabolism for optimal functioning, nitrogen and phosphorus are required in large amounts for organisms to survive.
What are macronutrients?It refers to those elements that provide energy to the body, these are proteins, carbohydrates and lipids.
Nitrogen and phosphorus, meanwhile, allow the development of metabolic processes, prevent infections and contribute to growth.
Therefore, we can conclude that the body requires a greater amount of macronutrients than micronutrients, nitrogen and phosphorus are required in large amounts for organisms to survive.

Regions that have similar climate characteristics can be widely spread apart, but typically have which of the following in common?
A: Varying altitudes and similar precipitation
B: Corresponding latitudes and continental locations
C: Corresponding temperature and wind patterns
D: Similar ocean currents and vegetation
C: Corresponding temperature and wind patterns are in common.
What are the 3 characteristics of climate?The simplest way to describe climate is to look at average temperature and precipitation over time. Other useful elements for describing climate include the type and the timing of precipitation, amount of sunshine, average wind speeds and directions, number of days above freezing, weather extremes, and local geography.
Climate features also include windiness, humidity, cloud cover, atmospheric pressure, and fogginess. Latitude plays a huge factor in determining climate. Landscape can also help define regional climate. A region's elevation, proximity to the ocean or fresh water, and land-use patterns can all impact climate.

what is the first layer of hair that is cut by scissors when receiving a hair cut?
Answer: the guide?
Explanation:
Cuticle is the first layer of hair that is cut by scissors when receiving a hair cut.
What do you mean by cuticle?The cuticle is a layer of clear skin located along the bottom edge of your finger or toe. This area is known as the nail bed. The cuticle function is to protect new nails from bacteria when they grow out from the nail root.
A cuticle is a hydrophobic boundary layer on the outer surface of primary aerial organs. Its presence is a common feature of all vascular and some non-vascular plants.
The cuticle plays an important role in nail health. They provide protection for the tissue that grows new cells to build nails. As you know, your nails are constantly growing, that's why you have to keep them manicured.

Explain how Earth's magnetic field is generated.
Answer:
The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.
Answer:
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet

An ecologist in Costa Rica wanted to determine the PGR for the country in 2018, and collected all of the data necessary to calculate the rate. She concluded that there were 34,560 births and 2,310 deaths within their population of 100,000. There were also 478 immigrants and 126 emigrants that year. What was the population growth rate for Costa Rica?
The population growht rate is 32.602 % per year. Population growth can be calculated as = (births + immigrants) - (deaths + emigrants).
In this case, population growth is equal to = (34,560 births + 478 immigrants) - (2,310 deaths + 126 emigrants) = 32,602 new individuals per year
Total (original) population: 100,000 _____ 100%
32,602 _____ X
In consequence, the population growth rate per year can be estimated by the following equation:
X = (32,602 x 100)/ 100,000 = 32.602 %

Why do we have high and low tides?
Answer:
It often accompanies a new moon and when the moon is closest to the Earth. The moon's gravitational pull on the Earth and the Earth's rotational force are the two main factors that cause high and low tides. Tides move around the Earth as bulges in the ocean.
Which of the following was developed following Griffith's 1928 experiment. A. Some pathogenic bacteria cannot be heat-killed. Bacterial virulence is related to temperature resistance. B. Streptococcus pneumoniae causes disease. C. DNA from dead encapsulated bacteria can transform living un-encapsulated bacteria into living encapsulated bacteria. D. Dead encapsulated bacteria can cause disease.
Answer:
I believe A is the answer, but I'm not positive.
Explanation:
Griffith demonstrated in 1928 that the ability to synthesis a capsule and consequently become virulent can be transferred from heat-inactivated “smooth” strains to surviving but avirulent “rough” strains of S. pneumoniae. Therefore, option (A) is correct.
What was Griffith's experiment?British bacteriologist Frederick Griffith's 1928 bacteria experiment was the first to demonstrate the "transforming principle," which led to the realization that DNA serves as the carrier of genetic information.
Griffith tried injecting mice with heat-killed S bacteria as part of his investigations (that is, S bacteria that had been heated to high temperatures, causing the cells to die). Unsurprisingly, the mice were not harmed by the heat-killed S bacterium.
The first study demonstrating that bacteria are capable of transferring genetic information through a process known as transformation was conducted by Frederick Griffith.

Which of the following describes why a glucose transporter is needed to move glucose into the cell?
Glucose is nonpolar and requires ATP to move across the membrane.
Answer A: Glucose is nonpolar and requires A T P to move across the membrane.
A
Glucose molecules are polar and need to move from low concentration to high concentration.
Answer B: Glucose molecules are polar and need to move from low concentration to high concentration.

Answer D: Glucose is large and polar and cannot pass through the phospholipid bilayer.
A glucose transporter is needed to move glucose into the cell because glucose molecules are polar and need to move from low concentration to high concentration.
What do you mean by Glucose Transporters?Glucose transporters may be defined as proteins that facilitate the transport of glucose across the plasma membrane.
Glucose transporters work with the concentration gradient. This process of moving glucose across the cell membrane is called facilitated diffusion.
Therefore, a glucose transporter is needed to move glucose into the cell because glucose molecules are polar and need to move from low concentration to high concentration.

Starch is found in foods such as peas, corn, and potatoes. For the body to receive energy from starch, it is broken down into smaller units. A mutation occurs in the gene that codes for a protein that breaks down starch.In which case will the mutation be harmful?
This mutation would be harmful for the body because, when not able to break down the starch and use it for energy, the body will begin to have starch buildup and not be able to do anything with it. It would continue to build up and do some serious damage everytime someone who has this mutated gene eats food rich in starch.
what happens when air masses of different temperatures meet?
Answer: When two air masses meet together, the boundary between the two is called a weather front. At a front, the two air masses have different densities, based on temperature, and do not easily mix. ... Winds are common at a front. The greater the temperature difference between the two air masses, the stronger the winds will be.
