what are the importance of planting and propagating trees and fruit bearing trees?
Answer:
Planting and propagating trees and fruit bearing trees are important because without these we won't have fruits to eat, our land will suffer from soil erosion, there will be landslide and flooding and we won't have fresh air to breathe.
Planting and propagating trees and fruit-bearing trees is important in a variety of ways:
Many fruits from trees serve as food for other organisms, including man. Fruits are rich in important nutrients that are essential for the health and survival of man.Trees are sources of timber for various construction works for man. Trees serve as habitats for other living organisms like insects, birds, etc. These organisms serve important ecological functions in the ecosystem.Trees are important for tackling water erosion. The roots of trees hold the soil structures together while their leaves reduce the force with which raindrops hit the ground.Trees help with carbon fixation. Thus, they help rid the environment of pollution and purify the air.Branches of trees also act as breakages during wind, thus, protecting the environment.More on the functions of trees in the environment can be found here: https://brainly.com/question/23108922
"Histology Lab Tissues are groups of cells with similar shape and function. The purpose of this lab is to give you experience looking at and identifying tissue slides taken from areas all over the body. Epithelium 1. What is the primary purpose of all epithelial tissue? 2. Besides skin, give two examples of different body "surfaces" that are exposed to the outside environment and would need a lining of epithelium. 3. Label the following as squamous, cuboidal, or columnar."
Answer:
1. The primary purpose of all epithelial tissue is to cover the different body surfaces, this includes cavities that are not in contact with the exterior and parts of the body that are in contact with the exterior.
2. Tongue and esophagus.
3. The images with the types of epithelium are attached.
Explanation:
The main purpose of epithelial tissue is to cover all the surfaces of our body. These are the cavities, and the parts that are in contact with the exterior. They create barriers that protect the body, secrete, absorb substances, allow the passage of specific elements, and stop the entrance of others. The functions vary according to where the tissue is in the body.
The tongue, as it is in contact with the exterior and with the food that enters our mouth, it has a stratified squamous epithelium. The thickness of this epithelium protects it against the different things that can damage or enter through it.
The esophagus has a nonkeratinized stratified squamous epithelium that protects the esophagus from the damage, that food or antigens may cause.
Squamous epitheliums have cells with a not specific shape that has their nucleus in the center.
Cuboidal epithelial have lined cells with a cuboidal shape.
Columnar epithelial have lined cells with a rectangular shape, and their nucleus is near the basal region.

What happens to the temperature of the water when it begins to melt?
Answer:
When you heat ice, its temperature rises, but as soon as the ice starts to melt, the temperature stays constant until all the ice has melted.
According to the graph, the temperature of the water continues to increase during the change of state. Thus, the correct option for this question is A.
What will happen if the ice melts?When the ice melts, the level of seawater would tend to be increased. This is because solid ice has tended to change its state to liquid. And now liquid may increase the density of the seawater which ultimately rises its level.
It is noted that when the temperature reaches that 0°C. For some instances of time, it will remain the same, but as time passes it tends to increase. The same principle is seen when the temperature reaches 100°C. So, it can not be said that the temperature remains at 0°C or 100°C until the changes in state.
Therefore, the temperature of the water continues to increase during the change of state. Thus, the correct option for this question is A.

Which statement is FALSE? First exclude the four that are correct. While performing photosynthesis during the day, the chloroplasts of a green leaf produce Which statement is FALSE? First exclude the four that are correct. While performing photosynthesis during the day, the chloroplasts of a green leaf produce ATP to be used in the Calvin cycle. ATP as an energy source for the roots of the plant. sugars for the green leaf’s cellular respiration at night. sugars as an energy source for the roots of the plant. sugars to fuel the growth of the plant.
Answer:ATP as an energy source for the roots of the plant.
Explanation:
Photosynthesis is the process by which plants manufacture their own food. It involves the combination of water and carbon dioxide in the presence of sunlight. Sugars are produced in the process.
The ATP molecules produced during photosynthesis are not transported to plant root cells. Rather, metabolic activities within the plant root cells produces the energy molecules required by the plant roots.

1. Compare and contrast internal fragmentation and external fragmentation. Explain the circumstances where one might be preferred over the other.
Answer:
Explanation:
Internal fragramentatoin is a form of fragmentation that occur when a process required extra or more space compared to the size of the memory block which is allotted and it is fixed . In order words it indicates that the process uses little space.
External fragmentation is a process that occur when the allotted memory size occur in different variable sizes.
Internal fragmentation is majorly used over external fragmentation when a process required more space than the allotted memory block size.
And external fragmentation is preferred over internal fragmentation when a process is detached or reduced from actual memory.

In most cases, mutations in the core of a protein that replace a smaller nonpolar side chain in the wild-type (e.g., Ala, Val) with a larger nonpolar side chain (e.g., Leu, Ile, Phe, Trp) in the mutant, result in significant destabilization and misfolding of the mutant. What feature of the protein core explains this observation? Why would such a mutation prevent a protein from folding properly? Match the items in the left column to the appropriate blanks in the sentences on the right.
Explanation:
we are required to fill in the blank spaces in the attachment.
protein side chains are non polar. so the first answer is non polar. These side chains are hydrophobic in nature. so the second blank is hydrophobic. Non polar substances are known to have large number of van der waal forces. the third answer is large and the fourth is vanderwaals contact. the protein core destabilizes only when there is a weakening of vanderwaals contact which brings about mutation.
dear user your answer should look like this:
Interactions of non polar side chains in protein sequence lead to the formation of a tightly packed hydrophobic core. This core is stabilized by a large number of vanderwaals contact. When a mutation occurs, it destabilizes the protein core and weakens vanderwaals contact leading to misfolding
Which of the following is not a cycle of matter?
O Nitrogen Cycle
O Energy Cycle
O Water Cycle
O Carbon Cycle
Nutrient cycle is also known as the cycle of matter. Nitrogen, water and carbon all three are cycle of matter but energy cycle is not. Thus, correct option is B.
What is Nutrient Cycle?
Cycle of matter are also known as Biogeochemical cycles. These cycle include both biotic and abiotic factors. Cycle of matter are described into five types based on matter: a. water cycle, b. nitrogen cycle, c. phosphorus cycle, d. sulfur cycle, e. carbon cycle.
Matter constantly moves in the cycle involving change in the state. The matter cycles are essential as they recycle important nutrients required for the survival of living organisms.
In contrast to this, energy flows in the atmosphere. It is the interaction between the energy sources within Earth. The interaction between energy sources and Earth's atmosphere is very significant and a small change could lead to significant change in climate behavior of an area.
Therefore, the correct option is B. Energy cycle is not a cycle of matter.

Polysaccharides are 1000s of monosaccharides joined together.These carbohydrates store energy and help build structural compounds. For example, plants use cellulose to build up their cell walls so they can stay rigid and grow towards the sunlight. Plants can store glucose energy in the form of starch in roots, fruits, and seeds. On the other hand, animals store glucose energy in the form of glycogen. When we don't have enough food to eat to replenish glucose in our cells, glycogen will release glucose energy as backup.
True or False??
Answer:
True
Explanation:
As rightly stated in this question, Glycogen is a carbohydrate which animalsa store glucose energy as. When we eat food, all parts is not converted to glucose, some is converted to glycogen, which is then stored in the liver and muscle tissues.
This stored glycogen, which is a polymer of glucose is broken down to glucose for use during a low supply of glucose to the cells. Hence, it is TRUE that when we don't have enough food to eat to replenish glucose in our cells, glycogen will release glucose energy as backup.

If you are looking at an object that measures 0.5 mm and the image you see is 10 mm long. Your friend is looking at an object that is 0.1 mm long using the same magnification. What is the size of image does your friend see?
The size of the image seen by a friend has been 2 mm.
What is magnification?Magnification can be given as the process of enlarging the image to a degree unlike the physical and the apparent size. The use of magnification glass has been forming the enlargement of the images or objects.
The magnification can be given as:
m = v/u
Where, m = magnification, v = object height, and u = image height
The size of the object (v) = 0.5 mm
The size of the image seen (u) = 10 mm
The magnification (m) of the image seen by a person has been:
m = 0.5 mm / 10 mm
m = 0.05
The image seen by a friend of the object (u) of 0.1 mm with a magnification (m) of 0.05 is:
0.05 = 0.1 mm/ u
u = 0.1 mm/0.05
u = 2 mm
Thus, the size of the image seen by a friend with the magnification same as the person has been 2 mm.
