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.

What is photosynthesis?
Answer:
it's a good question well photosynthesis is a process in which plants absorb the sun light and convert it to energy to prepare Thier food.
Photosynthesis is a process by which plants and other organisms, such as algae, convert solar energy into chemical energy and use it to produce organic molecules. Photosynthesis is the main source of energy in the biosphere.
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.

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.

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.

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 %

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.
B
Glucose molecules are charged, and charged molecules are only ever actively transported.
Answer C: Glucose molecules are charged, and charged molecules are only ever actively transported.
C
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.

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

Carnivores that eat other animals
Carnivores that eat other animals is a situation which shows a biotic factor operating within an ecosystem. Thus, the correct option is D.
What are the biotic factors?
A biotic factor in an ecosystem is a living organism which shapes its surrounding environment. In a freshwater ecosystem, the examples of biotic factors might include aquatic plants, fishes, amphibians, and algae population.
An example of biotic factor should consist of living organisms such as the one "Carnivores that eat other animals". In this example, carnivores are the animals which eat other lower animals for their nutrition. Both the organisms are living hence are the biotic factors of an ecosystem.
Biotic factors of an ecosystem depends upon the abiotic factors for their survival such as water, climate, soil, temperature, and atmosphere, etc.
Therefore, the correct option is D.
