What is evolution?
Evolution is defined as the theory in biology that various types of plants, animals, and other living things on Earth evolved from other preexisting types and that distinguishable differences are the result of modifications in successive generations.
There are basically four types of evolution.

✎﹏☾✦☁️❣️ Briefly explain the process of photosynthesis .❣️☁️
Answer:
hope this will help u
Explanation:
photosynthesis is the process in which plant make their own food with the help of sunlight,water and carbon dioxide. water and carbon dioxide are raw materials in photosynthesis because they help to prepare their food.During photosynthesis, plants take in carbon dioxide and water from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
Explanation:
PHOTOSYNTHESIS
This is a process in which green plants and other organisms make their own food from simple inorganic substances which are sunlight ,CO2 and chlorophyll.
Why do plants have trouble growing in space?
Answer:
The first challenge in growing plants in space is how to get plants to grow without gravity. This runs into difficulties regarding the effects of gravity on root development, providing appropriate types of lighting, and other challenges
Answer:
because, The first challenge in growing plants in space is figuring out how to get them to thrive in the absence of gravity. This presents difficulties in terms of the impact of gravity on root growth, as well as the provision of adequate lighting and other issues.
Explanation:
Gravity has an impact on root formation, but the scientists discovered that their space plants didn't need it to thrive. The space flowers showed common root growth patterns such as "skewing," where roots slant slowly as they branch out, when grown on a nutrient-rich gel in transparent petri plates.

What characteristics do you think an animal would have in order to survive in the savanna environment?
Answer:
The type of biome that is made up of scattered grasses and small tress and shrubs is called the savannah. The ecosystem consisting of small community of plants and animal on a large piece of land is is called a biome.
Because the tress are small and scattered this enable the grasses to thrive in the savannah. They are located in the hot and warm climate across the world with the annual rainfall of 50.79 to 127 cm per year. This is estimated t be about 100 '' of rainfall per year .This is fall within certain months, and there may be fire outbreaks when the rain stops or in droughts.
Therefore lack of moisture is the features of the savannah. Plants and animals in this terrestrial biome must develop adaptive features for water conservation to survive with little exposure of the to heat and sunlight to prevent excessive dehydration.
The plants have narrow leaves to reduce the surface area to volume ratio exposed for transpiration and evaporation of moisture
some have underground stem and root for storing starch and water.
Cactus is an example of plant with thick stem to conserve water ,and spikes to prevent been eaten by herbivores
The animals have good stamina to withstand dehydration, and are less active duding the day to conserve body water, and do reduce exposure to the hot and arid environment.
Elephants has wrinkle skin to reduce water loss ,and large ears to dissipate heat.

Scientists now classify all living things into 6 kingdoms. Which of the following groups of organisms is classified into the greatest number of kingdoms?
A. multicellular animals that are larger than humans
B. humans and other multicellular organisms that are about the same size as humans
C. plants and animals that are smaller than humans but still visible
D. organisms that are microscopically small and each made of a single cell
humans and other multicellular organisms that are about the same size as humans.
What are 6 kindgoms?
The greatest classification for all organisms in biological taxonomy is called a kingdom. In taxonomy, there are 6 kingdoms. These six kingdoms comprise all forms of life. Eubacteria, Archae, Protista, Fungi, Plantae, and Animalia are the six kingdoms.
Most scientists believed that all living things could be categorized as either plants or animals up until the 20th century. However, most biologists realized in the 1950s and 1960s that this approach was insufficient for fungus, protists, and bacteria.
A classification scheme known as the "Five Kingdoms" came to be acknowledged as the standard by which all living things may be arranged by the 1970s.
Therefore, humans and other multicellular organisms that are about the same size as humans.
