Explanation:
state the importance of calcium and zinc in our body
Answer:
Calcium is a mineral found in many foods. Almost all calcium is stored in bones and teeth to help make and keep them strong. Your body needs calcium to help muscles and blood vessels contract and expand, and to send messages through the nervous system. Calcium is also used to help release hormones and enzymes that affect almost every function in the human body.
Zinc, a mineral that people need to stay healthy, is found in cells throughout the body. It helps the immune system fight off invading bacteria and viruses. The body also needs zinc to make proteins and DNA, the genetic material in all cells. During pregnancy, infancy, and childhood, the body needs zinc to grow and develop properly. Zinc also helps wounds heal and is important for our ability to taste and smell. Zinc is found in a wide variety of foods, and is found in most multivitamin/mineral supplements.

Ryland is setting up a cooler to store flowers for a big event. Which of the following is NOT going to contribute to ethylene build up in his cooler?
O Gas leaks
O Succulents and cacti
O Old flowers
O Ripening fruit
Answer:
Gas leaks
Explanation:
I don't know anything about biology but I know gas leaks aren't good for plants
The option that will not contribute to ethylene building up in Ryland's cooler would be gas leaks.
Ethylene plant hormoneEthylene is an important hormone for plants that regulate processes such as leaf/fruit abscission, fruit ripening, and senescence.
Thus, keeping succulents and cacti, old flowers, and ripening fruit in the cooler would be a good recipe for ethylene building up in the cooler.
Gas leaks may not find its way into the cooler as long as it is closed.

Lipids, carbohydrates, and DNA all exist in human cells as long molecular chains. Which of the following describes how DNA differs from lipids and carbohydrates?
A. Only DNA has carbon Atoms
B. Only DNA is found in the cytoplasm
C. Only DNA is needed to create new cells
D. Only DNA contains genetic information
Answer:
D. Only DNA contains genetic information
Explanation:
DNA has the main function of carrying genetic information.
On the other hand, lipids and carbohydrates have the main functions of being energy sources.
Lipids are used for long term energy storage, while carbohydrates are used for quick energy.
DNA is different from lipids and carbohydrates because it contains genetic information, while the others don't.
So, the correct answer is D. Only DNA contains genetic information
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.

✎﹏☾✦☁️❣️ 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.
