Sydney and Valparaiso are the same distance from the equator and both are near the ocean. Is Valparaiso warmer, colder, or the same temperature as Sydney?

Answers

Answer:

They are the same in temperature both of Valparaiso and Sydney because they have equal distance from the equator and the same geographical location which gives sense that they are similar in weather patterns and climate but depends on phenomenal events.

Explanation:

The Equator is the imaginary middle latitude, which divides the Earth into Northern and Southern hemispheres.

Sydney and Valaparasio are equidistant from the equator and have the same climatic conditions.

Sydney is located 2,340 miles away from the equator. The city is located near the ocean and enjoys a sunny climate with warm summers and little winters. The average temperature ranges between 18.6-degree to 25.8-degree Celcius.

Valparaiso is situated 2,284 miles away from the equator and near the ocean. The city enjoys mild winters, humidity, and comfortable summers. The average temperature of the city ranges between 14-degrees to 30-degrees.

However, the other phenomenal events can cause a change in the climatic conditions of a city.

What is the relationship between diploid cells and homologous chromosomes??

Answers

Haploid and diploid chromosomes are two types of chromosomes present in cells. Then, both have differences with regard to the number of chromosomes. Of course, the number of chromosomes in the cell content.

Chromosomes are double helix structures, which then accommodate the DNA and proteins present in the cell. In other words, chromosomes are strands of DNA chains containing the genes in living organisms. Then as a container for DNA and cell protein.

Furthermore, it will help in packing DNA. There is a long homologous chromosome with a centromere position and the staining pattern is the same as the gene in the appropriate location characteristics.

Which of the following represents an interaction between the biosphere and the atmosphere

A. Precipitation is absorbed into the ground
B. Plants take in carbon dioxide from the air
C. Ice melts the causing sea levels to rise
D. Humans drink springwater

Answers

Answer: A

Explanation:

Precipitation is absorbed into the ground represents an interaction between the biosphere and the atmosphere. Thus, the correct option is A.

What is the interaction between biosphere and the atmosphere?

The interaction between biosphere and the hydrosphere, includes the biosphere which requires water to drink for animals and for the growth of plants which are present in the biosphere. Water is provided by the hydrosphere through precipitation. This interaction between the hydrosphere and biosphere helps the life on Earth to be more sustainable.

Plants draw water and different nutrients from the soil and release water vapor into the atmosphere. This is possible by the precipitation which results into the absorption of water and minerals into the ground.

Therefore, the correct option is A.

Animals like sea turtles and dolphins would be found in the neritic zone.
T or F

Answers

Answer:

T ~ True

Explanation:

The neritic zone is the region of shallow water (200 meters depth) above the continental shelf where light penetrates to the sea floor. Due to the abundant supply of sunlight and nutrients in this zone, it is the most productive ocean zone supporting the vast majority of marine life. As a result, many organisms that require light for photosynthesis can live in this zone, including seaweeds and phytoplankton. Most coral reefs are also found in the neritic zone. ... Swimming organisms in the pelagic zone include dolphins, whales, squid, and numerous species of fish adapted to life at different depths.

Svetlana learned that there are organisms that live deep in the ocean that produce food using energy stored in chemicals.

What process do these organisms most likely use to produce food?

Answers

Answer:

chemosynthesis

Explanation:

the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.

There are two various ways by which organisms produce food. This is through photosynthesis which is utilized by plants and chemosynthesis which is utilized by some other organisms.

The process by which organisms that live deep in the ocean produce food using energy stored in chemicals is through chemosynthesis.

Organisms that live deep in the ocean are unable to access sunlight to enable them produce their food so they use the process of chemosynthesis.Chemosynthesis is utilized by some bacteria. They do this by using chemicals in the place of sunlight unlike photosynthesis as a source of energy to produce food (glucose). It involves the conversion of one or more carbon-containing molecules (e.g methane) into organic matter using the oxidation of inorganic chemicals.
