For the first page: These adaptations are advantageous. For example, the dart frog’s bright colors warns predators to stay away from them. This will help them survive because they will not be bothered by any predators. Because the Hosta lives in such a crowded environment it is to its advantage that it has big leaves to get as much sunlight as possible. This makes it more likely to survive than other plants. Both of these advantages help the living thing to be stronger.
For page 2: These adaptations are advantageous. The Toucan has a long and narrow beak that helps it get fruit other birds cannot get. This gives them access to more food which can help them outlive other birds. The Monstera plant has adapted so that it does not mold. This helps it stay healthy whereas other plants may grow mold. These two organisms have adapted so that they have one sure advantage that will help them live longer than other species. The advantages are different but they both serve the same purpose.

Like i dont know how to explain and what animal please help

Answers

Answer:

Adaptation can protect animals from predators or from harsh weather.

Explanation:

Many birds can hide in the tall grass and weeds and insects can change their color to blend into the surroundings. This makes it difficult for predators to seek them out for food.

Adaption can protect them

Use the information and pictures to answer the following question.

In August 2010, the Asian Clam was discovered in Lake George. It is not native to that lake. A single Asian Clam can reproduce and release hundreds of offspring in a day. Fish and crayfish eat the clams but cannot keep pace with the rate at which the clams reproduce. The Asian Clam eats the same food as native clams.

A scientist set up two model lakes in large tanks with the same animal species as Lake George in order to test how the Asian Clam might be impacting the ecosystem. The scientists added Asian Clams to one tank but not the other tank.

image

Which statement BEST predicts what would likely happen in the experimental tank?

A.
The impact would be negative because it would reduce the amount of food available for the fish and crayfish populations.

B.
The impact would be positive because it would reduce competition with native clams and increase the stability of the ecosystem.

C.
The impact would be negative because it would increase competition with native clams and reduce the stability of the ecosystem.

D.
The impact would be positive because it would provide the fish and crayfish populations with food.

Answers

Answer:

C.The impact would be negative because it would increase competition with native clams and reduce the stability of the ecosystem.

Explanation:

Since, It states that:

Tank 1:                                                   Tank 2:

Fish                                                             Fish

crayfish                                                   crayfish

Asian clam                              

-------------------------------------------------------------------------------------------------------------

Thus, since they both eat Asian clam which means competition as well as  it would be negative. Therefore, that left us with [C] .

Hence, Answer = [C]

Heres the text
In the spring of each year, the second largest dead zone in the United States forms in the Gulf of Mexico. During the spring, farmers fertilize their land as they prepare for crop season. As a result, nutrients from the fertilizers, such as nitrogen and phosphorus, drain into the Mississippi River and eventually the Gulf of Mexico. According to the National Oceanic and Atmospheric Administration, “Excess nutrients that run off land or are piped as wastewater into rivers and coasts can stimulate an overgrowth of algae, which then sinks and decomposes in the water” (NOAA, 2018). The decomposition process consumes and depletes oxygen levels in the Gulf of Mexico, which causes hypoxic areas or dead zones.



A group of scientists measured several water quality parameters to better understand how dead zones in the Gulf of Mexico impact brown shrimp populations over time. The scientists are most interested in the dissolved oxygen levels because the levels are critical for the survival of brown shrimp populations. Brown shrimp populations thrive when dissolved oxygen levels in the Gulf of Mexico are greater than 2 mg/L. However, the populations cannot thrive when dissolved oxygen levels are at or below 2/mg/L.

If we know myofibrils are made of protein strands, what would expect to find a large number of in the myofibrils themselves.

Answers

Answer:

the Z lines and thick filaments of the myofibrils within the muscle fibers are aligned.

Explanation:

Myofibrils are made up of units that repeat along their length, called sarcomeres.

What is Myofibril what are its myofilaments?

Every muscle cell contains contractile protein filaments of two types: actin and myosin. These myofilaments (or myofibrils) are distinguished from one another by molecular weight, which is higher in the myosin filament.

With this information, we can conclude that myofibrils are made up of units that repeat along their length, called sarcomeres.
