Answer:
The three different ways are mentioned as under:
1) Wind dispersal
2) Dispersal by water
3) Dispersal by animals
Explanation:
1) Wind dispersal: Wind dispersal is very common mode of seed transfer from one plant to another plant. Seeds of some plants are light in weight. Therefore, they can be easily blown away from one plant at a particular region to another region which is distantly located. Some examples of such plants are kauri, maple trees etc.
2) Water dispersal: The seeds of some plants are dispersed by water. In this way of dispersal, the seeds are blown away by flowing water. This mode of seed dispersal is not very common. The seeds of vallisneria, sea grass etc. are dispersed by water.
3) Dispersal by animals : Seeds can be dispersed by animals too. When animals pluck the fruits from a plant and eat the fruit, the seed of that fruit enters their digestive tract. When those animals excrete, that time the seed comes out of their digestive tract and grow as an independent plant. Some animals pluck the fruit and eat the pulp and throw the seed at far away place from the tree. That seed then grows as an independent tree at a distantly located area. Examples are : Mango tree, raspberry etc.

Explain the reproductive advantage that an angiosperm (like apple trees) would have over mosses
Answer:
Angiosperm´s seed have outer protection and an endosperm
Explanation:
Mosses reproduce through the use of spores. The angiosperms reproduce by seeds, seeds offers many advantages, they have outer protection, a shell that protects the inside from damage, desiccation and adverse conditions. Seeds also have endosperm as nourishment for the embryo instead the spore doesn't have any built-in system to help a new mosses begin the growth process.
Angiosperms didn't need to rely on the wind or water to spread their pollen around, they need a pollinator.

Which best describes nitrogen fixation? Nitrogen fixation is the process of creating free nitrogen for plants to absorb. Nitrogen fixation is the breakdown of nitrogen in the soil. Nitrogen fixation is the conversion of nitrogen gas into a usable form. Nitrogen fixation is the destruction of the bonds between nitrogen and other elements.
Answer:
C. Nitrogen fixation is the conversion of nitrogen gas into a usable form.
Explanation:
The process of assimilation of atmospheric nitrogen into organic compound by some type of micro-organisms is called nitrogen fixation. It is the conversion of nitrogen gas into a usable form for plants and other microbes.
What are the steps in nitrogen cycle?Nitrogen is the most important complex for the environment and is the most abundant gas. Nitrogen fixation is a step by step procedure that involves various steps.
The steps of nitrogen fixation is as follows:
Nitrogen fixation: nitrogen enters soil and surface waters, here it gets converted into two atoms, which combines to form ammonia.Nitrification: The conversion of ammonia into nitrates and nitrites. It involves different kinds of bacteria.Assimilation:The consumption of nitrites and nitrates by plants.Ammonification: it is the release of nitrogen back to organic form by death of plants and animals.Denitrification: The conversion of ammonia back to nitrogen is called as denitrification.Thus, the correct option is C.

A client who has been taking diazepam for 3 months for skeletal muscle spasms and lower back pain has stopped taking the medication 2 days ago because it was no longer helping. now the pain has increased. the nurse should assess the client for: (select all that apply.)
Final answer:
After stopping diazepam, a client may experience several withdrawal symptoms. The nurse should assess for insomnia, diaphoresis, tremor, and vomiting, which are among the common withdrawal effects after ceasing benzodiazepine treatment.
Explanation:
The subject in question concerns the potential withdrawal symptoms that a patient might experience after stopping diazepam, a medication from the benzodiazepines family. Diazepam is often prescribed for anxiety, insomnia, seizures, and muscle spasms. Given that it is a CNS depressant, abrupt discontinuation after prolonged use can lead to withdrawal symptoms which the nurse should assess.
Insomnia - A common withdrawal symptom due to the rebound effect after cessation of a medication that has sedative properties.Euphoria - Not typically associated with withdrawal; euphoria might be a side effect when using the drug but not when discontinuing it.Bradycardia - Not commonly reported as a withdrawal symptom from benzodiazepines, typically withdrawal could cause increased heart rate rather than slowing it down.Diaphoresis - Withdrawal can induce excessive sweating as the body reacts to the absence of the medication.Tremor - A common symptom of withdrawal from diazepam as the body's nervous system becomes hyperactive.Vomiting - A notable withdrawal symptom that can occur after stopping diazepam.Therefore, the nurse should assess the client for insomnia, diaphoresis, tremor, and vomiting as these are symptoms commonly associated with withdrawal from diazepam.

An 8-ounce glass of low-fat chocolate milk contains 160 kilocalories (kcal) and 8 grams of protein. what percent of the kcal in the milk comes from protein?
Final answer:
Protein provides 4 kilocalories per gram. Multiplying the 8 grams of protein in the milk by 4 kcal/g gives 32 kilocalories from protein. This makes up 20% of the total 160 kilocalories in the milk.
Explanation:
To calculate what percent of the kilocalories in the milk come from protein, we need to know how many kilocalories are provided by the protein. Protein provides 4 kilocalories per gram, so if the milk contains 8 grams of protein, the protein contributes:
8 grams of protein x 4 kcal/g = 32 kilocalories from protein.
Next, we'll find the percentage of the total calories that come from protein:
(32 kilocalories from protein / 160 total kilocalories) x 100 = 20%
Therefore, 20% of the kilocalories in the low-fat chocolate milk come from protein.

How does the adrenal gland respond to stress? the adrenal cortex secretes mineralocorticoids and glucocorticoids in response to short-term stress. the adrenal medulla secretes epinephrine and norepinephrine in response to long-term stress. the adrenal cortex secretes epinephrine and norepinephrine in response to short-term stress. the adrenal medulla secretes epinephrine and norepinephrine in response to short-term stress. the adrenal medulla secretes mineralocorticoids and glucocorticoids in response to long-term stress?
The adrenal medulla secretes epinephrine and norepinephrine in response to short-term stress. The adrenal cortex responds to long-term stress by secreting glucocorticoids and mineralocorticoids, which affect various metabolic processes and are necessary for the body to adapt to chronic stress conditions.
The question concerns how the adrenal gland responds to stress. In response to short-term stress, the adrenal medulla secretes epinephrine and norepinephrine, which are hormones that mediate the fight-or-flight response. This process is mediated by the sympathetic nervous system (SNS). On the other hand, the adrenal cortex is responsible for responding to long-term stress by secreting glucocorticoids like cortisol and mineralocorticoids like aldosterone after being stimulated by adrenocorticotropic hormone (ACTH) from the anterior pituitary gland, which is triggered by the hypothalamus.
The corticosteroids released by the adrenal cortex play essential roles, from affecting glucose metabolism and stimulating glucose synthesis to the breakdown of fat into fatty acids in the adipose tissue which are then used for ATP production. Such hormones are necessary for the body's adaptation to long-term stress conditions but should not be used excessively in a medicinal capacity due to potential immune-suppressing effects, such as increased susceptibility to disease.

Which part of the neuron sends messages to other neurons?
Answer: Axon
An axon is part of neuron with long single fiber that sends messages to the dendrites of other neurons. They transmit information away from the cell body and may have myelin covering to protect the axon and help to fasten the speed of transmission of the signal that deliver the message to other neurons, tissue like the muscles and organs.
The axon of the neuron is responsible for sending messages to other neurons. It transmits electrical signals known as action potentials, which trigger the release of neurotransmitters at the axon terminals. These neurotransmitters then carry the message across the synaptic gap to the next neuron.
Explanation:In a neuron, the part that sends messages to other neurons is called the axon. The neuron generates an electrical signal known as an action potential, which travels down the axon towards the axon terminals. There, it triggers the release of neurotransmitters, which are chemical messengers that transmit the signal to the next neuron across the synaptic gap.
The typical neuron structure comprises the cell body, dendrites, axon, and axon terminals. Out of these, the axon plays a pivotal role in carrying these messages or impulses from the neuron to other neurons, which could be located in different parts of the body.

Which sentences describe decomposers in a food chain
Bacteria, fungus, worms, and snails recycle the waste of dead materials and give back nutrients to the ecosystem, according to the definition of decomposers in a food chain. So, the correct option is D.
What are Decomposers?Organisms known as decomposers convert decayed organic matter, such as that of dead plants and animals, into more basic substances like nutrients and minerals. Following their release back into the ecosystem, these less complex substances are utilised for growth and development by other organisms.
By dissolving decayed organic debris and returning the nutrients to the soil, which plants can use to thrive, decomposers perform a critical function in the ecosystem. By preventing nutrients from being lost and allowing them to be reused by other living things, this recycling mechanism aids in maintaining ecological equilibrium.
