✎﹏☾✦☁️❣️ 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.

During an El Niño event, farmers in the southwestern United Stated often benefit from which of the following climatic changes? Longer and cooler summers that increase crop yield
Answer A: Longer and cooler summers that increase crop yield A Wetter and warmer weather that increases soil moisture
Answer B: Wetter and warmer weather that increases soil moisture B Cooler and drier conditions that help cold-weather crops
Answer C: Cooler and drier conditions that help cold-weather crops C Warmer and drier weather that reduces soil erosion and flooding
Answer:
The answer is "Wetter and Warmer weather that increases soil moisture".
Explanation:
During the El Niño event, growers inside the southwestern of the USA often profit from hot weather and much more global warming in moisture in the soil.
Its surface waters were considerably warmer than usual in the eastern Pacific Ocean. Its transition is tightly linked with the atmosphere as well as the winds around the large Pacific.
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.

Stars are hot objects and give off heat and light. Scientist can collect this energy and tell what two things about stars (even though we cannot observe or measure the star directly).
a.composition
b.temperature
c.exact mass
d.shape
Answer: A or c
Explanation:
Stars are hot objects and give off heat and light. Composition and exact mass are the things about stars.
What is Stars?A star is the most well-known celestial object and the main building block of galaxies. The age, distribution, and composition of a galaxy's stars can be used to determine the galaxy's history, dynamics, and evolution.
In addition, stars generate and disperse heavy elements like carbon, nitrogen, and oxygen, and their characteristics are strongly tied to those of any planetary systems that may develop around them.
The study of the origin, development, and death of stars is thus at the heart of astronomy.
Therefore, Stars are hot objects and give off heat and light. Composition and exact mass are the things about stars.

Would it be justified to call Kreb's Cycle the central wheel of metabolism? Why? Provide two specific pieces of evidence to support your answer.
Answer:
Yes.
Explanation:
Kreb's Cycle is considered as the central wheel of metabolism because the fuel molecules are oxidized ultimately within the Krebs Cycle and its intermediates are used for various biosynthetic pathways. The main function of the Kreb's cycle is to produce electron carriers that can be used in the cellular respiration for producing energy molecules in the form of ATP. without Krebs's cycle, the cell produces only two ATP molecules which very low.

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.
