Answer: here is an answer sorry if it's not what u were looking for but I have no information to correctly answer this ques
Explanation:
In the areas with lots of human interference, human activity has contributed to a lower biodiversity. People might litter on the ground or simply step on animals. Other times, people may add chemical fertilizers and pesticides to the soil. These activities all contribute to a loss of biodiversity. A low biodiversity is unfavorable because these ecosystems take longer to recover from environmental changes.

Were does all the energy start from ALL the organisms
Answer:
The sun
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.
(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)
Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).

The pressure zone that separates the Westerlies and Easterlies in the northern and southern hemisphere is called the___________
Answer:
intertropical convergence zone
Explanation:
At the intertropical convergence zone near the equator, where the trade winds from the northern and southern hemispheres converge, the air rises, producing a belt of weak, light, shifting winds called the doldrums.
The pressure zone that separates the Westerlies and Easterlies in the northern and southern hemispheres is called the Subpolar lows.
In the Subpolar regions (60° to 65° lat North/South), the rotation of the earth creates a low-pressure belt in this area.The subpolar low is a region of winds that circles the Earth at the subpolar low-pressure belt.In conclusion, the pressure zone that separates the Westerlies and Easterlies in the northern and southern hemispheres is called the Subpolar lows.Learn more in:

List 3 negative impacts does plastic pollution have on the ocean?
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

2.As pollen travels down the stamen, fertilization occurs and a seed is produced.
3.When the ovule receives pollen, fertilization occurs and a seed is produced.
4.When the stigma receives pollen, a seed is produced and then fertilization occurs.
Answer:
Pretty sure its #3
Explanation:
Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. ... The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.
Why it was important that Gregor Mendel used thousands of pea plants in his experiments? Would Mendel have found the same results if he had used only twenty plants? Explain.
Answer:
Explanation:
Gregor Mendel used thousands of pea plants in his experiments to ensure that his results were accurate and reliable. By using a large sample size, he was able to reduce the effects of chance and random variation in his experiments. This is important because biological systems are complex and variable, and small sample sizes can lead to inaccurate or misleading results.
Mendel's experiments involved crossing pea plants with different traits (e.g., tall vs. short, yellow vs. green), and he counted the number of offspring with each trait. He found that the offspring followed predictable patterns of inheritance, which he summarized in his laws of inheritance.
If Mendel had used only twenty plants in his experiments, he may not have obtained the same results. With a small sample size, chance events can have a greater impact on the results. For example, if he crossed two pea plants with different traits and obtained only a few offspring, it's possible that chance events (such as mutations or environmental factors) could have influenced the results. This could lead to false conclusions about the inheritance of the traits.
Therefore, using a large sample size was critical to Mendel's success in developing his laws of inheritance. It allowed him to detect patterns that were consistent across many different crosses, and to demonstrate that these patterns were not the result of chance variation.
