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.

Which statement describes the ability of the cell membrane to allow various substance to move through it?
The cell membrane is selectively permeable.
how many chromosomes do human sperm and egg cells have?
How long does it take the Earth to move from Point A to Point C?
Answer:
Explanation:
As you know that the earth has two types of motions,
namely rotation and revolution. Rotation is the
movement of the earth on its axis. The movement of
the earth around the sun in a fixed path or orbit is
called Revolution.
The axis of the earth which is an imaginary line,
makes an angle of 66½° with its orbital plane. The
plane formed by the orbit is known as the orbital plane.
The earth receives light from the sun. Due to the
spherical shape of the earth, only half of it gets light
from the sun at a time (Figure 3.2). The portion facing
the sun experiences day while the other half away from
the sun experiences night. The circle that divides the
day from night on the globe is called the circle of
illumination. This circle does not coincide with the
axis as you see in the Figure 3.2. The earth takes about
24 hours to complete one rotation around its axis.
The period of rotation is known as the earthday. This is
the daily motion of the earth.
2021–22
MOTIONS OF THE EARTH 19
Figure 3.3 : Revolution of the Earth and Seasons
What would happen if the earth did not rotate? The
portion of the earth facing the sun would always
experience day, thus bringing continuous warmth to
the region. The other half would remain in darkness
and be freezing cold all the time. Life would not have
been possible in such extreme conditions.

Explanation:
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.

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.

Sickle-cell anemia is a genetic blood disorder. Red blood cells normally have a round shape and pass easily through small blood vessels as they deliver oxygen to the tissue. But in people with sickle-cell anemia, some red blood cells are shaped like a sickle, or a "C." The red blood cells with this sickle shape do not live as long as healthy, round blood cells.
The sickling of red blood cells is thought to be due to problems with the hemoglobin gene. The unusual behavior of the hemoglobin causes rigid fibers of protein to form in the cell membrane, leading to a decrease in its flexibility and the change in cell shape. These rigid, deformed cells are more likely to rupture or get stuck in small blood vessels, creating a blockage. When blood flow to tissues is interrupted, this can lead to long-term damage to organs and even cause death.
1. a) Based on the information above, what are at least two changes that take place in the red blood cells of individuals with sickle-cell anemia? (2 points)
it delivered oxygen easily
in sickle it cause problem
Explanation:
it because their blood cell is not spherical

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

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.

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 %
