Answer:
This is due to lactic acid accumulation in Emma's leg muscles.
Explanation:
In the absence of oxygen in the muscle cells, the cell switches from performing aerobic respiration to lactic acid fermentation. The lactic acid fermentation produces lactic acid as a product, which builds up in the muscle cells of the body causing a burning sensation and pain. This often happens during exercises.
This is the cause of Emma's pain in her lower leg muscles. Lactic acid has been formed and accumulated in the muscle cells of her leg during the exercise with her brother.

Sarah thinks that the number of worms on the sidewalk in front of her house increases after a rainfall. Which would be the best way to test her prediction?
Answer:
To collect data about the population of worms before and after the rainfall.
Explanation:
The best way to test her prediction, we have to wait for the rain and collect the data after the rain and before the rain. The difference between shows the result whether she is right or wrong. In my opinion, she is right because the worms comes out from the soil in order breathe. The rain water block the porous spaces in the soil through which the oxygen enters into the soil and the worms can breather so due to blocking no oxygen for them so they come out from the soil after rainfall.

d phytoplankton - krill – fish –
Answer:
The answer is B.
Explanation:
If you are looking for biggest to smallest this is the answer. Or, who eats who.
Answer:
A
Explanation:
Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Then fish get eaten by large predators, such as sharks, tuna, squid and octopus as well as marine mammals like seals and some whales form the top of the food chain. Next a shark is eaten by a whale. These whales have been known to attack and eat everything from small fish and turtles to squid, seals, sea lions, and even large whales. Killer whales also hunt, attack, and eat sharks. That is a food chain from smallest to biggest :)

The
_________.
Answer:
seperate
template
origin
During replication, the two DNA strands separates and each chain serves as a template for a new nucleotide chain. The sites where DNA replication and separation occur are called the origin.
What is DNA replication?DNA replication defines the biological process of making two identical copies of DNA from a single original DNA molecule. It occurs in all living organisms which acts as the most essential part for biological heritage.
During DNA replication, each of the two strands forming the double helix serves as a template from which the new strand is copied, while these new strands will be complementary to the parental or "old" strand. Each new double strand consists of a parent strand and a new daughter strand.
Steps involved in the DNA replication are:
1. Initiation
2. Elongation
3. Termination
Thus, during replication, the two DNA strands separates and each chain serves as a template for a new nucleotide chain. The sites where DNA replication and separation occur are called the origin.

Type the correct answer in the box. Spell all words correctly. What is the name of this ocean? The blank Ocean has the deepest depression in the world, called the Mariana Trench.
Answer:
Pacific Ocean
Explanation:
thats where it is
The Pacific Ocean has the deepest depression in the world, called the Mariana Trench. The Mariana Trench is the deepest part of the world's oceans, located in the western Pacific Ocean.
Explain The Pacific Ocean.The Pacific Ocean is the largest and deepest ocean in the world, covering an area of about 63.8 million square miles and accounting for more than one-third of the Earth's total surface area. It is located between Asia and Australia to the west, and the Americas to the east.
The ocean is known for its diverse marine life, including whales, sharks, dolphins, and various species of fish. The name "Pacific" was given to the ocean by Portuguese explorer Ferdinand Magellan in 1521, who called it "Mar Pacifico," meaning "peaceful sea," due to the calmness of its waters at the time.
However, the ocean is not always peaceful and is prone to natural disasters such as typhoons, hurricanes, and earthquakes due to its location on the "Ring of Fire," a region of intense seismic activity.
The Mariana Trench reaches a maximum depth of about 36,070 feet (10,994 meters) and is located on the floor of the western North Pacific Ocean, east of the Mariana Islands. The trench is crescent-shaped and about 1,550 miles (2,500 km) long, with a width of only 44 miles (70 km). It was named after the Mariana Islands, which are nearby.
