The graph below shows the averaged sunspots from 1610 to 2007. The graph shows sunspot number on the y axis and years 1600, 1650, 1700, 1750, 1800, 1850, 1900, 1950, and 2000 on the x axis. The graph rises and falls in a cyclic order in gaps of approximately 10 years. The number of sunspots observed in 1610 was 40, in 1650 it was 5, in 1700 it was 10, in 1750 it was 90 and the number of sunspots in 1800 was 50. The number of sunspots observed in 1850 was 130 and the number of sunspots in 1900 was 10. The number of sunspots observed in 1950 was 150 and the number of sunspots observed in 2000 was 30. Based on the graph, which of these conclusions is correct? Some of the previously warm regions became colder from 1650 to 1700. Some of the previously cold regions became warmer from 1600 to 1700. Some of the previously warm regions became warmer from 1610 to 1700. Some of the previously cold regions became colder from 1900 to 1950.
Answer: Some of the previously warm regions became colder from 1650 to 1700
Explanation: I got it right on the test
According to the graph, the number of sunspots decreased from 1650 to 1700. That means the correct option is A.
What is a sunspot?The areas of the sun where the magnetic field of the sun is 2500 times more than the Earth. In these areas, the magnetic field is more than anywhere else on the surface of the sun.
Near the area of a sunspot, there is a small amount of energy output from the sun. UV rays from the sun also increase at a high sunspot activity. This increase in UV radiation causes dramatic effects on the atmosphere of the Earth.
The more number sunspots are observed, the more energy will be delivered to the earth. This increase in the energy delivered to the earth would result in an increase in the overall global temperature.
According to the graph, the number of sunspots observed decreased from 40 to 5 and increased slightly from 5 to 10 from 1610 to 1700. So, the statement says that some of the warm regions would become colder from 1650 to 1700.
Therefore, the correct option is A.

For example, plasma membrane proteins carry out functions as diverse as ferrying nutrients across the plasma membrane, receiving chemical signals from outside the cell, translating chemical signals into intracellular action, and sometimes anchoring the cell in a particular location.
Answer:
All cells have plasma membranes. Can molecules enter and leave the cell? Yes. The plasma membrane (also called the cell membrane), is a lipid barrier where molecule organelles live. The golgi ( a cell organelle) helps move the proteins across the plasma membarane. Proteins cannot move through the plasma membrane barrier by themselves because they are not small enough like water.

Explain how carbon cycles through the ecosystem in which you live.
PLEAASE HELP :((
Answer:Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?
Answer:
This question is incomplete, the complete question is as follows:
- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.
What percentage of offspring are expected to be chestnut?
The answer is 0%
Explanation:
This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.
According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;
BB - B only
bb - b only
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
Bb, Bb, Bb, Bb
All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0% of offspring are expected to be chestnut.
Answer:
