What is the difference between mechanical weathering and chemical weathering?
Answer:
Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.

How do atmospheric conditions influence weather patterns?
Answer:
Air pressure is influenced by the differences between hotter and cooler pockets of air, or fronts.
Explanation:
When atmospheric pressure is low, air is pushed down toward the surface, meaning rain and moisture don't accumulate. This often also leads to high humidity near the surface of the Earth, where people experience weather. hope this helps you :)

Describe the application of mitosis in agriculture and food technology with example.
please help me
Answer:
Explanation:
Mitosis is a form of cell division that takes place in the nucleus, it involves series of steps from prophase to metaphas to anaphase and Telophase. It results in the formation of two daughter cell that are genetically identical with the parent having the same number of chromosome.
Mitosis helps in the formation of new cells, it replaces the old cells with new one. Living things are made up of cells including plants and this cells when worn out are been replace through mitosis division to aid good growth pattern.
Mitosis helps in producing the exact copy of cell from the parent leading to genetically identical offspring having the important features, traits as the parents that can be useful in agriculture.
A actively dividing cells aids growth, water melon is a fruits its growth is aid by mitosis.
Each cells has Identical DNA(Deoxyribonucleic acid) with chromosome located in them.
This chromosome can be doubled to get polyploid.
Polyploid have led us to existence of new varieties of crops such as the seedless water melon, wheat.

Unattached earlobes is a dominant trait, E. A parent who is homozygous for unattached earlobes is crossed with a parent who is homozygous for attached earlobes. Which describes the genotypes of their offspring?
Answer:
Homozygous Dom and Homozygous recessive traits are both shown.
Look below for answer V
Explanation:
Considering that both are homozygous, that means that both traits are of the same kind.
Unattched earlobes is dominant, which means its sign would be (EE)
Attatched is the recessive, which means its sign would be (ee)
On a table, the genes would look this way-
EE EE
ee Ee Ee
ee Ee Ee
Since there is a dominant trait in all of the genes, the children would 100% have unattached earlobes.
(As a counter situation, if the unattatched was heterozygous, the chance of attatched to unattatched would be 50/50 as theres no dominant trait lurking)
I may be incorrect but i hope this helps!
The actual alleles that an organism possesses make up its genotype. The appearance or characteristic of an organism is known as its phenotype. A person would have detached earlobes if their genotype was Ee.
What are the Unattached earlobes genotype?The person who has free earlobes and is heterozygous has the genotype Ee and is capable of producing both the E and e alleles.
Punnett's squares are a good illustration of this. The person who has linked earlobes has the genotype ee and is only capable of producing e alleles.
All the genes have a dominant characteristic, therefore all the offspring would have detached earlobes.
Since there is no hidden dominant characteristic, (as a counter example, if the unattached was heterozygous, the risk of attached to unattached would be 50/50)

You notice two birds living in different parts of the same tree outside your house. They have similar markings and are of a similar size. After continual observation, you realize that they cannot interbreed. Do these birds belong to the same population? Why or why not.
Answer:
They do not belong to the same population
Explanation:
These two similar birds do not belong to the same population because a population is made up of groups of similar organisms of the same species that occupy the same geographical region including the capability to interbreed. This two birds despite the similar markings, they do not have the capability to interbreed thus they are not of the same population.
Answer:
The correct answer is "The two birds do not belong to the same population because they cannot interbreed".
Explanation:
A population is defined as a group of individuals of the same species living in the same are at the same time and with the capability of interbreeding. In this case the two birds share the same area and time, but they are not able to interbreed. Excluding the possibility that the two birds are of the same sex, we can speculate that the two birds are of the different species even though they look very similar. Therefore, we can conclude that the two birds do not belong to the same population.

Which substance would most likely form sedimentary rock?
O cooled lava
melted rock
changed igneous rock
small pebbles
Answer:
small pebbles
Explanation:
Small pebbles would most likely form sedimentary rock.
What are sedimentary rocks?Sedimentary rocks are formed from the accumulation and cementation of small rock particles or sediments such as sand, silt, and clay, as well as other materials like shells, organic matter, and minerals that have been weathered and eroded from pre-existing rocks.
Over time, these sediments are compacted and cemented together to form solid rock. Therefore, small pebbles are more likely to be transported by wind or water and deposited as sediment, eventually forming sedimentary rocks through compaction and cementation. Cooled lava, melted rock, and changed igneous rock are more likely to form igneous rocks through solidification or crystallization.

Does Astigmatism cause blindness? Can Astigmatism be cured?
Answer:
Astigmatism is a problem of how the eye focuses light typically caused by a defect in the lens, resulting in distorted images. Astigmatism is not an eye disease or health problem. While it can cause blurred vision, eye strain, and headaches, particularly after prolonged reading, it does not cause blindness.
Astigmatism can be corrected with glasses, contact lenses, or refractive surgery (i.e. laser eye surgery), although treatment may not be necessary if the symptoms are mild. Glasses and contact lenses both compensate for the irregular shape of the cornea and help to focus light properly into the back of the eye

What is one of the drawbacks of the Linnaean system of classification?
Answer:
The correct answer is : lack of molecular evidence.
Explanation:
The Linnaean classification system was depended on clear physical qualities. It comprises of a chain of command of taxa, from the kingdom on the top to the species as more specific taxa. Every species is given a one of a kind two-word Latin name. The system is based completely on physical characteristics of organisms, due to lacking the proper technology to investigate the molecular data of animals .
Thus, the correct answer is : lack of molecular evidence.

The spicules of sponges are made up of caco3 (non living ) but why they have endo skeleton?While endoskeleton is living
Answer: The spicules of the sponges are made up of calcium carbonate and silica. These structures are present in the body of sponges to provide them support and protection.
The sponges have the endoskeleton in the body which is developed by the specialized cells of the body.
The endoskeleton of the sponges are known as spicules. Actually the outer body of the sponges are very soft and internally has endoskeleton for protection which is a bit hard as it is made of silicon dioxide or calcium carbonate.
