Answer:
Over millions of years, the shape of mountains on Earth’s surface can change to low hills and then to rolling plains. These changes are most likely caused by weathering and erosion.
These changes are most likely caused by weathering and erosion
What is weathering and erosion?weathering is the breakdown or dissolution of rocks and minerals. After a rock has been broken down, the bits of rock and minerals are carried away by erosion.
Erosion is a geological process in which natural forces like as wind and water wear away and transfer earthen materials.
How does weahering and erosion cause breakdown of large hills?weathering and erosion speeds up the process of breaking down of a mountain. Erosion speeds up tectonic processes beneath the mountains by lowering the weight of the mountain range. Wind, rain, and ice increase at higher elevations and directly effect the weathering and erosion process, causing mountain tops to weather more quickly.Hence the mountain will change into a valley over many years followed by eroding into rolling plains.learn more about Weathering and erosion here:

Answer:
water, compost , and chemical fertilizer
Water, compost , and chemical fertilizers is the best for maintaining the long-term health of farm soil.
What do you mean by chemical fertilizers?Chemical fertilizers, such as urea, diammonium phosphate (DAP), and single superphosphate (SSP), are used to maintain the shortage of nitrogen, phosphorus, and potassium in the soil.
Most fertilizers that are commonly used in agriculture contain the three basic plant nutrients: nitrogen, phosphorus, and potassium. Some fertilizers also contain certain "micronutrients," such as zinc and other metals, that are necessary for plant growth.
Chemical fertilizers will nourish your plant, but the minerals will not linger in your soil. By creating rich, nutrient-dense soil with organic materials, your lawn will have a better chance of thriving on its own tapping into stored minerals when needed.

Wolves employ a variety of non-vocal forms of communication to express and maintain their status,
Explanation:
Answer:
Communication is especially important for animals, like wolves, that live together in family groups, where coordinating, cooperating, and reinforcing bonds and status are all part of a necessary daily routine. Within a family of wolves, communication helps maintain social stability. It helps to reinforce pack solidarity and enables the opportunity for young pack members to learn information specific to the pack and how to survive.
Communication is also used to express an individual’s intentions or emotional disposition or feelings. As with any highly social animal, communication amongst wolves is particularly complex and involved and it is vital to keeping the family functioning together as one. Wolves do use a range of vocalizations to “talk” to one another and express themselves.

What is the adrenal gland?The adrenal gland is an endocrine gland located on top of each kidney. It is divided into two parts: the adrenal cortex and the adrenal medulla. The adrenal cortex produces hormones such as cortisol, aldosterone, and sex hormones, which are involved in a variety of processes in the body, including metabolism and salt and water balance. The adrenal medulla produces hormones such as adrenaline and noradrenaline, which are involved in the "fight or flight" response.

When igneous rock is formed,the size of the rock crystals or grains is primarily dependent on
Answer:
The three factors that influence the textures of igneous rocks are the speed of cooling, the silicate content, and the water content.
Igneous rocks contain randomly arranged interlocking crystals. The size of the crystals depends on how quickly the molten magma solidified: magma that cools slowly will form an igneous rock with large crystals. lava that cools quickly will form an igneous rock with small crystals. When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

What natural features are important in the transfer of sand from one side of an inlet to the other:
Answer:
What causes sand to move along a beach?
Sand grains move along the shore and up and down beaches because of currents made by waves. Waves break when they reach shallow water, creating turbulence. This area is called the surf zone. When waves break, some of the force is turned into currents
The natural features that are important in the transfer of sand from one side of an inlet to the other may include weathering and erosion.
How does sand move along a beach?Sand grains move along the shore and up and down beaches because of currents made by waves. Waves break when they reach shallow water, creating turbulence. This area is called the surf zone. When waves break, some of the force is turned into currents.
Most beaches get their sand from rocks on land. Over time, rain, ice, wind, heat, cold, and even plants and animals break the rock into smaller pieces. This weathering may begin with large boulders that break into smaller rocks. Water running through cracks erodes the rock. They also prevent seawater from entering wells and ponds.
Therefore, the natural features that are important in the transfer of sand from one side of an inlet to the other may include weathering and erosion.

Answer: High tryptophan: The tryptophan binds to the trp repressor and causes it to change shape, converting into its active (DNA-binding) form. The trp repressor with the bound tryptophan attaches to the operator, blocking RNA polymerase from binding to the promoter and preventing transcription of the operon.

How is the reproductive rate of marine mammals
related to their status in regards to extinction?
Answer:
The fewer fish the less that can reproduce.
Explanation:
marine mammals with a slower reproductive rate are especially sensitive to disturbance , environmental changes and anthropogenic sources of stress because when populations of these organisms decline, recovery is especially slow . it takes a significant amount of time for these animals to reach reproductive maturity and they are commonly heavily invested in raising only one or two young ones every two to three years on average . therefore , populations of marine mammals with slow reproduction are in imminent danger when multiple sources of envirnmental pressure are acting in tandem over an extended period of time . The fewer fish the less that can reproduce.
More the reproductive rate, lesser the extinction and lesser the reproductive rate, more is the extinction.
What is reproductive rate?
The reproduction rate measures the conditions under which generations are replaced. This calculation can be made taking account of mortality (net reproduction rate) or without mortality (gross reproduction rate).
What is extinction?Extinction is a situation in which something no longer exists.
When the reproductive rate of marine mammals will be less, they will not be able to cover up the loss/death of their species caused by any reason and will ultimately lead to extinction.

Substance A has an LD50 of 3 milligrams per kilogram of body mass for a species of fish. Substance B has an LD50 of 10 milligram per kilogram of body mass. Which substance is considered more deadly?
Substance A
Substance B
They are equally deadly.
This cannot be determined without the ED50.
Answer:
LD50 means a lethal dose of a particular substance or drug is given to a group of animals in a test group. This dose has the ability and capacity to kills 50% of the population of the test group of animals.
If Substance A has an LD50 of 20 mg/kg of body mass, this means that for 1 kg of body mass, 20 mg of substance A can kill 50% of the population that substance A was given to the test group.
If Substance B has an LD50 of 10 mg/kg of body mass, this means that for 1 kg of body mass, 10 mg of substance A can kill 50% of the population that substance B was given to the test group.
Therefore, Substance B is deadlier than Substance A because the quantity of substance B (10mg) is less than the quantity of Substance A (20mg) and it has the same lethal effect on the population.

Answer:
True
Explanation:
Pollen consists of one or more vegetative cells and a reproductive cell. A pollen grain itself is not the male gamete. In angiosperms and certain gymnosperms, the vegetative cell forms the pollen tube that grows to meet the unfertilized ovules, and the reproductive cell is the source of the sperm.
