what is weathering?
Answer:
Weathering is the breaking down or dissolving of rocks and minerals on Earth's surface.
Explanation:
Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

What is the main difference between heterotrophs
Answer:
Heterotroph. Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms — both plants and animals — for nutrition.

Identify the types of point mutations depicted.
Answer:
The types of point mutation depicted are:
1. C. Silent mutation
2. B. Nonsense mutation
Explanation:
Point mutation is known to be a mutation that actually affects a single nucleotide and it has to do with the substitution of one base for another. This substitution can occur by changing, inserting or deleting a DNA or RNA sequence. A nonsense mutation refers to a change in DNA which leads a protein to either terminate or end its translation so quickly than expected. This mutation is commonly seen in humans.
Silent mutation is known to be the mutation in DNA whereby there are no effects which are observable in an organism's phenotype. This type of mutation are seen as a specific type of neutral mutation.

Which types of leaves do better in colder climates? Why?
Answer: Deciduous plants handle the lack of water by shedding their leaves, which tend to evaporate water into the air. During cold winter months, most deciduous plants drop their leaves and go dormant. Evergreen plants keep their foliage, but their leaves and needles have a thick, waxy coatings to reduce water loss.

How would a volcanic eruption on the mainland of the U.S. affect your daily life?
Answer:
Pyroclastic flows are mixtures of hot gas and ash, and they travel very quickly down the slopes of volcanoes. They are so hot and choking that if you are caught in one it will kill you. ... Some of the good ways that volcanoes affect people include producing spectacular scenery, and producing very rich soils for farming.
:))i forgot to add... Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields.
A volcanic eruption on the mainland of the U.S. could potentially disrupt transportation, power and communication systems, cause damage to infrastructure and homes, and create hazardous air and ash conditions, potentially affecting daily activities such as commuting and accessing necessities.
What are effects of volcanic eruption?A volcanic eruption on the mainland of the U.S. could have a significant impact on daily life, depending on the location and severity of the eruption. If the volcano is located in a heavily populated area, it could cause widespread destruction, loss of life, and displacement of residents. The ash and debris from the eruption could also cause damage to infrastructure, making it difficult to travel, communicate, or access essential services.
Additionally, a volcanic eruption could cause power outages, water shortages, and other public health and safety concerns. If the eruption is severe enough, it could disrupt food production and transportation, leading to shortages and rising prices. If the eruption occurs in a less populated area, it may not have as much direct impact on daily life, but it could disrupt travel and commerce, and cause air and water quality issues.

Lithium has one valence electron while Oxygen has six. If lithium atoms bond with
oxygen atoms, what will be the correct chemical formula?
OLIO
Li2O
OLI 02
O Li 06
Since Lithium has one valence electron that means it needs to lose it to form a stable structure. That means it's valence is equal to one. Oxygen has six atoms, in order to form a stable octet structure it needs to accept 2 electrons, therefore it's valence is 2.
Therefore two Lithium atoms bond with one oxygen atom to form Li2O

Why is having a cell that is too large detrimental?
Explanation:
If a cell became too large, an "information crisis" would occur. The cell has more trouble moving enough nutrients and wastes across the cell membrane. The rate at which food, oxygen, and water enter the cell, as well as wast products leave the cell, depends on the surface area of the cell and the cell's volume.

5. What is the difference between locomotion in plants and animals?
pls help he guyzzz
Answer:
Animals can move, but plants cannot
Explanation:
Locomotion in humans and bipeds is accomplished through walking on legs. In other animals, it can be accomplished through walking on four limbs, flying, or swimming. In cells, cilia and flagella are used to move about. However, since plants are not capable of moving themselves, there is no locomotion of plant species.

Answer: An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.

What do plants produce when they make their own food?
Answer:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Explanation:
Answer:
Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch
