Interference from the sun causes data to be collected inaccurately.
Answer:
C. Local variations in weather are too small for weather instruments to replicate.
The rain predictions made by meteorologists are sometimes incorrect as local variations in weather are too small for weather instruments to replicate. The correct option is c.
Who are meteorologists?Meteorologists are both observers and investigators. They take note of the physical conditions of the atmosphere above them and research maps, satellite data, and radar data.
A meteorologist is a professional who uses scientific principles to explain, understand, observe, or forecast the earth's atmospheric manifestations and/or how the atmosphere impacts the earth and life on the planet.
Meteorological was the name he gave it because it dealt with things that fell from the sky, such as meteors. Because he or she studies what falls from the sky, a person who forecasts the weather is known as a meteorologist.
Meteorologists' rain predictions are sometimes incorrect because local variations in weather are too small for weather instruments to replicate.

Our current rockets would take tens of thousands of years to get to even the nearest star, 4.3 ly away. If we invent a spacecraft that can travel 0.1 the speed of light, how long would it take to travel to the nearest star?
- 4.3 ye
- 3.8 x 10^14 yr
- 43 ly
- 1.9 x 10^7 yr
Answer:
It will take the rocket 43 light years to get to the nearest star
Explanation:
1 light year = 9.46 * 10¹⁵ m
speed of light = 3.0 * 10⁸ m/s
In one year, light travels a distance of 1 light year.
A rocket with that travels with a speed 0.1 * the speed of light will travel the distance of one light year in 1/0.1 = 10 light years
Therefore, it will take the rocket 10 * 4.3 light years to get to the star = 43 light years.
43 light years = 43 * 9.46 * 10¹⁴ m = 4.07 * 10¹⁷ m
What is the geographic area where a given population is found? carrying capacity population density distribution range
Answer:
range
Explanation:
The geographic area where a given population is found is referred to as its distribution range. The geographic or physical boundaries that make up a given population of organisms are represented by the distribution range.
On the other hand, carrying capacity refers to the most members of a species that a particular habitat or ecosystem can support over the long term. It is the maximum population that may exist indefinitely without seriously affecting the environment or exhausting its resources.
A measure of how packed or concentrated a population is in a given area is called population density. The usual unit of measurement is the number of people per unit of habitat or land area. Within a distribution range, population densities can change between areas, indicating how individuals are dispersed within the available environment.

What best describes the role of the squirrel in the food web?
Answer:
[tex]\boxed {\tt C. \ A \ primary \ consumer \ that \ is \ food \ for \ a \ single \ predator, \ the \ hawk}[/tex]
Explanation:
First, let's examine the food web and focus on the squirrel. The grass points to the squirrel which points to the hawk. There are no other arrows involving the squirrel.
Therefore, the squirrel is only food for the hawk. We can eliminate A and B.
Now, let's focus on the last two answers. The difference between C and D is C says "primary consumer" and D says "secondary consumer". Let's define these terms.
Primary consumer
Consumers that eat plantsSecondary consumer
Consumers that eat primary consumersThe arrow points from the grass to the squirrel. The arrow represents energy flow, so the energy flows from the grass to the squirrel (the squirrel eats grass). Grass is a plant, so a squirrel is a primary consumer.
The correct answer is C. A primary consumer that is food for a single predator, the hawk
Describe the concept of natural selection, using the Galapagos finches as an example. Imagine you were trying to explain the concept to someone who did not know what it is.
Answer and Explanation:
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population. It is a consequence of the individual differential capability to reproduce and leave offspring. There must be also a genetic base called heritability. Natural selection involves interactions between individuals, the physical environment, and the biological environment.
Natural selection results in adaptation, an increase of the aptitude phenotype. In many cases, adaptations, resulting from natural selection, can be correlated to environmental factors or selective pressures applied by other organisms.
The selective agent is the environmental characteristic that determines the differential survival of the phenotypic classes.
Some intraspecific phenotype variations follow a geographical distribution and can be correlated to changes in environmental conditions, such as temperature or humidity.
Adaptive evolution refers to changes in the organism that lead to the evolution of the species and that are adaptive to certain conditions of the environment. Birds adapt to diverse ecological niches showing specialized beak forms to improve functions such as feeding, mating, defending, competing, and etcetera. These factors play an important role in beak shaping. Natural selection produces adaptive evolution.
During 1977 Daphne Major island went through an important drought, and many plant species produced few or no seeds during and after the event. The medium ground finch population, which is seed-feeder species, was hardly affected by this phenomenon. As seeds´ production dropped and the sizes of the extisting seeds were considerably smaller, the finch population declined drastically from about 1400 individuals to a few hundred in a period of two years, approximately. The fact is that the island weather controls plant species development, and thus, seeds availability as food for the birds. Years later after the drought, the finches population managed to recover but showing differences in the size of their beaks. Before the drought finches had a stubby beak and many years after recovering the average size of the beaks was larger than the beak size of the original population. This difference in phenotype was due to the fact that during the drought, small seeds were very scarce, but large seeds with thick husks were still available. Small birds with small beaks starved because they were not able to open the husk and eat the interior of the seed. But those birds with bigger and stronger beaks were able to do so, and hence, managed to survive. The bird population adapted to the new environmental conditions and resource availability. Natural selection acted on the beak size, changing it.
There are different kinds of natural selection, but in the present example, directional selection is operating.
Directional selection increases the proportion of individuals with an extreme phenotypic trait, in this case, large beaks. This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
Furthermore, beak size is not only related to feeding strategies, but also to reproduction. Female finches only mate with males that have the same beak size.

A cell can be compared to a business. The Nucleus controls all cellular functions like a Chief Executive Officer that controls all of the operations and decisions of the business. Within the business there is the cytoplasm. The Cytoplasm in a cell, harbors cell organelles and provides structure. This compares to the factory work space that contains all the working bio-machinery and the nutrients, like the raw materials, for the cellular processes. The Cytoskeleton for a cell is what provides the shape and structure to the cell. This is compared to the architecture structure of a factory. It helps to support and strengthen the structure of the building. The Endoplasmic Reticulum of a cell is the site for protein synthesis, the vesicle packaging and transport. This is compared to an assembly line of the business. This is the main work space for production of the important cell components, for example the proteins. The Golgi Apparatus of the cell is the packaging of molecules into the transport vesicles. This is compared to the packaging department of a business. The packing department is the department that packages the goods that have been prepared. The Lysosomes of the cell is actually the membrane-bound cell organelle. It contains the digestive enzymes that break down the excess or the otherwise known worn-out parts of the cell. If the cell is considered damaged beyond repair it will help it to self-destruct with a process that is called programmed cell death. This is compared to the maintenance department of a business. The maintenance department is called in when there is old worn out machinery that needs replaced and discarded. The Mitochondria of the cell is in charge of producing the energy through cellular respiration. This is compared to the power plant or the generator of the business to help the production of energy. There are a few extra parts of the cell that could not be put on the chart above. The Plasma membrane of the cell is the semi permeable that controls cellular transport. This is compared to the Logistics department of the business. This department is in control of what is shipped in and out of the business. The last one is the Ribosomes of the cell. This Ribosomes are like the protein builders or the protein synthesizers of the cell. This is compared to the factory workers of the business. The works build the products for the company.

Cushing syndrome is caused by an increase in the synthesis of cortisol in the adrenal gland. Which of the following compounds is directly required as a substrate for the synthesis of this hormone?
A) cholesterol
B) glucose
C) free fatty acids
D) amino acids
Answer:
Cholesterol
Explanation:
Cushing Syndrome occurs as a result of exposure of the body to elevated levels of cortisol hormone (stress hormone) for a long time. The elevated level of cortisol which is a steroid hormone, results from increased synthesis of cortisol in the adrenal glands. Cortisol is synthesized from a substrate called, cholesterol. Cortisol synthesis occurs in the zona fasciculata of the adrenal cortex and controlled or regulated by the hypothalamus-pituitary-adrenal axis or HPA axis.
Cholesterol, which is an important substrate in cortisol synthesis, is a lipid usually found in cells and plays an important function in hormone synthesis, food digestion and synthesis of Vitamin D.

how does a plant get water form the ground
Answer:
Plants absorb nutrients and water through their roots, but photosynthesis — the process by which plants create their fuel — occurs in the leaves. Therefore, plants need to get fluids and nutrients from the ground up through their stems to their parts that are above ground level.
Explanation: How does a plant get water form the ground.
Answer:
It uses roots that suck up the water.
Explanation:
The roots are like tiny straws located in the bottom of a plant. They suck up water which goes up the stem. And the plants use that water to make food.
