Answers
Answer:
it’s A
Explanation:
Biodiversity dropped due to reduced wildlife habitat shows one consequence of urban sprawl.
What is Biodiversity?Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi.
While Earth’s biodiversity is so rich that many species have yet to be discovered, many species are being threatened with extinction due to human activities, putting the Earth’s magnificent biodiversity at risk.
The vast variety of life on Earth is referred to as biodiversity. It can be applied more precisely to all the species found in a certain area or environment.
Therefore, Biodiversity dropped due to reduced wildlife habitat shows one consequence of urban sprawl.

Seed Germination Investigation
The students are to investigate the process of seed germination during their summer
vacation.
They will select different types of seeds, such as beans, peas, or sunflower seeds.
Encourage students to set up a germination experiment by placing the seeds in
different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to
pot the same seed in more than one pots.
They should observe and document the changes that occur over time, including the
emergence of roots and shoots.
Answers
Answer:
Okay...In this case I suggest you use corn seed or beans seed
Explanation:
It should take about 6 weeks to see the Germination, until then continue watering it and giving it sunlight
The seed germination investigation during the students' summer vacation involves selecting various seeds (e.g., beans, peas, sunflower) and setting up an experiment. They will place the seeds in different conditions, like light vs. dark or wet vs. dry, and pot the same seed in multiple pots. Throughout the investigation, the students are expected to carefully observe and document the changes that take place over time, including the growth of roots and shoots. This hands-on approach allows them to gain practical knowledge of seed germination and develop essential scientific skills in observation, data collection, and documentation.

Explanation:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.
Answer:
PhotosynthesisExplanation:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.Animal cells must work together in order to obtain nutrients and produce energy. Students were asked to create an explanation about the organelles involved in this process. Which student’s explanation is correct?
A. Student D is correct because they said the cell membrane allows the nutrients into the cell and the cytoplasm allows the nutrients to move across to the cell to be broken down by the mitochondria to create energy, and the lysosome gets rid of waste.
B. Student A is correct because they said the nucleus provides the organelles instructions to carry out their jobs, the lysosome breaks down the nutrients to create energy, and the mitochondria gets rid of waste.
C. Student B is correct because they said the nucleus provides the organelles instructions to carry out their jobs, the cell membrane stores the nutrients until the mitochondria breaks them down to create energy.

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)
Answers
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.

Explain the cell theory
Answers
Answer:
Explanation:
The cell theory basically just tells you that all living things have more than one cell and that cells are made from other cells. It basically just tells you that cells are our foundation for life, without cells we can't live.
For, example, blood cells. If we didn't have blood cells our body's organs can't get the oxygen and nutrients they need to survive. Without blood cells we could get weak or we could just die instantly.
Hope this helps!!!
The basic tenets of cell theory are that all living things are made up of cells and that cells are the basic units of life. However, cell theory dives deeper than that. ... In other words, everything is made up of cells. Cells are the basic building blocks of organisms and of life.

Binary Fission
Explanation:
Binary Fission is when an one organism splits itself into two basically.
Budding is when another organism sprouts from the 'parent' organism and eventually breaks off.
Fragmentation is when the parent organism loses a limb, and the limb grows into another organism.

Adaptations are special features that allow a plant or animal to live in a particular place or habitat. These adaptations might make it very difficult for the plant to survive in a different place. This explains why certain plants are found in one area, but not in another.
