Sar and Dagon are the same distance from the equator, and they are
both near the ocean. Using the information in the map, how does the air
temperature of Sar compare to the air temperature of Dagon? Why The
air at Sar is?
Answer:colder
Explanation:colder than Dagon. The winds push ocean water that turns and follows the coasts. Energy is transferred from the air to the ocean at Sar and energy is transferred from the ocean to the air at Dagon.

8. The graph below shows the reaction rates of two different reactions. Which of the following statements could explain the difference in the two reactions?
Answer:
These two reactions have different reactants, bonding and catalysts.
Explanation:
The two reactions are different from one another due to fusion of different reactants as well as different products. These two reactions may have different types bonding i.e. covalent, ionic or metallic bond etc between their atoms. In these two reactions, different types of catalyst are used which helps in speedup the chemical reaction so we can conclude that these two reactions have different reactants, bonding and catalysts in their chemical reaction.

Beginning around 1750,the global human population began to grow at much faster then it had in the years before this time.What caused this to change in the population growth rate?
Answer:
The cartogram is made up of squares, each of which represents half a million people of a country’s population. The 11.5 million Belgians are represented by 23 squares; the 49.5 million Colombians are represented by 99 squares; the 1.415 billion people in China are represented by 2830 squares; and the entire world population of 7.633 billion people in 2018 is represented by the total sum of 15,266 squares. It started in 1798, to the 1800. This period is when the human population began to grow at a faster rate then any other time in history. The answer is 300 years ago.
Explanation : Births - usually measured using the birth rate (number of live births per 1,000 of the population per year). Deaths - usually measured using the death rate (number of deaths per 1,000 of the population per year). Migration - the movement of people in and out of an area.
What is an example of a relationship between organisms in which an organism produces energy that is used by another organism to The detriment of the original organism
Answer:
Tree frogs use plants as protection. Golden jackals, once they have been expelled from a pack, will trail a tiger to feed on the remains of its kills. Goby fish live on other sea animals, changing color to blend in with the host, thus gaining protection from predators.

Tell me a brief summary of what happens in meiosis
**will mark brainliest**
Meiosis is a special type of cell division, which occurs only in the germ cells during the process of development and maturation to form gametes. It consists of two successive cell divisions,
Meiosis 1 : First meiotic division, that reduces the NUMBER of chromosomes i.e. the parent cell is diploid(46 Chromosomes) and the daughter cells are haploid(23 Chromosome). It also causes genetic variation in the haploid by cross linkage.Meiosis 2 : Second meiotic division (Meiosis II) starts with two haploid parent cells and ends with four haploid daughter cells. Meiosis 2 like Meiosis 1, does not reduce the NUMBER OF CHROMOSOME that means the forming 4 daughter cells are haploid and their number of chromosome remains the same as the parent. BUT Haploid cells that go into the meiosis 2 have MORE AMOUNT OF CHROMOSOME THAN USUAL, thus MEIOSIS 2 REDUCES the amount of chromosome rather than the number of chromosome.The DNA of the primitive germs cells is replicated prior to the meiosis 1 only and there is no replication of DNA before Meiosis 2. The four final cells reulting from the two meiotic divisions are not only haploid(i.e. containing 23 chromosome) but they are also containing 1n amount of DNA so that when the gametes fuse together forming a zygote, both the amount and number of chromosome and DNA remains SAME.
_____________________________________[tex]\huge{\text{Why is Meiosis Important?}}[/tex]Meiosis is essential for the sexual reproduction of eukaryotic organisms because it enables genetic diversity through recombination, and the repair of genetic defects.
It contributes in genetic reassorment which ensures the genetic diversity in the offsprings. The genetic reassortment takes place by following two mechanisms:
During the prophase of meiosis 1, crossing over of genetic material between the homologous maternal and paternal chromosomes takes place which causes exchange of DNA fragments between the chromosome resulting is genetic diversity.During the anaphase of the first meiotic division, there is random distribution of maternal and paternal homologous chromosomes among the daughter cells which are produced as a result of meiotic division._____________________________________Best Regards,'Borz'Can someone give me 4 causes and effects in how organisms and humans affect the enviroment?

Vascular resistance is due to friction between blood and the walls of the blood vessel. Which of the following causes low vascular resistance?
obesity
dehydration
high blood pressure
cholesterol levels within normal range
Answer:
Cholesterol levels within normal range
Explanation:
Vascular resistance is due to friction between the blood and the walls of the blood vessel, and cholesterol levels within the normal range can cause low vascular resistance, which is the last option.
What is vascular resistance?Vascular resistance is the resistance to blood flow in the blood vessels, which is determined by the diameter of the blood vessels, blood viscosity, and the length of the blood vessels, so when blood flows through the blood vessels, it experiences frictional forces due to the interaction between the blood and the walls of the blood vessels, obesity, dehydration, and high blood pressure can all contribute to increased vascular resistance.
Hence, the correct answer is that cholesterol levels within the normal range can cause low vascular resistance, which is the last option.

Astronomy question i need help cause i never to space and i have to imagine if i was and I'll also mark Brainiest for best answer help me plz
Answer:
Looking at the sky during night is always an amazing scene. It takes our breath away, every time when we see the night sky with countless stars twinkling, full moon and planets. I always wished I reach those far planets travelling in space. The only way I can fulfill my dream is to become an astronaut. Astronaut is a person who is trained to travel in a spaceship to go to outer space. If I were an astronaut, I wish my first mission will be to the moon. However, I will have to undergo a very strict training to survive in space We all have seen the training videos of astronauts in DISCOVERY channel where they even undergo underwater training. Life in space will be different with zero gravity and so we will experience zero weight and will float freely. Wow!!!! that seems to be an exciting thing. But how we will eat and drink?
Explanation:
if you want to imagine about space
first of all you need to clear your mind
and you need to concentrate your mind on the space and imagine .if you are not getting anything then drink some water and repeat the same process . I hope you will be successful to imagine space ..
best of luck
