please help, will give brainliest!
Answer:
It is all about the tilt of the Earth’s axis. Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun in January!
Explanation:
Answer:
because it’s rotation around sun
Because of its location north of the Equator

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.

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.
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]

The red dots represent oxygen molecules in this diagram. This diagram shows __________.
facilitation diffusion
osmosis
diffusion
exocytosis
endocytosis
The correct answer is option B.
Diffusion is the process of movement of both the solute and solvent. the characteristic of diffusion is that it does not require a membrane or a layer separating two parts. In diffusion particles or solutes move from a region of higher concentration to a region of lower concentration.
In the example, we can see that red particles are together in a place and after some time they get distributed evenly in the entire liquid. This process is known as diffusion as it does not require a membrane.

A triathlete swims a distance of 3 kilometers in 1 hour, then bikes a distance of 50 kilometers in 3 hours, and finally then runs a distance of 12 kilometers in 1 hour.
Part A) What is the Total distance the triathlete cover?
Part B) What is the Total time?
Answer:
Then the triathlete bikes a distance of 50 kilometers in 3 hours. Finally, the triathlete runs a distance of 12 kilometers in 1 hour. The average speed of the triathlete is the total distance divided by the total time. The triathlete's average speed is 13 kilometers per hour.

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

How do digital signals compare to analog signals in terms of data transmission over long distances? Please write in an easy way so I can understand what your saying.
Answer:
Explanation:
The difference between analog and digital technologies is that in analog technology, information is translated into electric pulses of varying amplitude. In digital technology, translation of information is into binary format (zero or one) where each bit is representative of two distinct amplitudes.
If we know myofibrils are made of protein strands, what would expect to find a large number of in the myofibrils themselves.
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.

Why is humus an effective fertilizer? (Select all that apply.)
It is abundant in inorganic nutrients.
It is dense and does not contain organic matter.
It is rich in organic matter.
It doesn’t need microorganisms to decompose matter.
The answer is: They are rich in organic matter.
Why are they rich in organic matter?
This is because humus is made out of dead plants, fruits, and sometimes even animal waste. Which is all good for growing plants.
This is the only answer because the rest are wrong.
This is a 1-1 answer, meaning this is the only one that is correct.

Make 2 full sentences using the scientific term "homoozygous" and 2 full sentences for "heterozygous (Side note: i had to add an extra O to the first thing so its not considered a offensive word-Thank you for your help!)
Answer:
1. If you have two copies of the allele for brown hair, you are homoozygous for that trait.
2. If you have two copies of the allele for brown hair, you are homoozygous for that trait.
3. Since sickle cell disease requires two alleles that are alike, a person with a heterozygous would not have the disease.
4. If both gene alleles are different, the organism is heterozygous for that particular trait.

predators and parasites both cause harm to other organisms. what is a difference between predators and parasites?
a. predators only kill at night, while parasites only kill during the day,
b. predators eat organisms, while parasites live off of organisms,
c. predators only harm producers, while parasites only harm consumers,
d. predators harm their young, while parasites do not
Answer: The predator kills the prey at once and has it in the form of food whereas parasite lives in or on another organism and benefits by deriving nutrients at the other's expense. This type of interaction is called as parasitism, Therefore the answer is b.
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.

along the leaf blade
throughout the veins
in the chloroplasts
between the xylem tissue
Answer:
in the chloroplast
Explanation:
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
Answer:
in the chloroplast
Explanation:
the chloroplast is what allows to have color and absorb the light from the sun
