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.

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.

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.

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.

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.
