Explanation:
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information
The the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.
The plasma membrane is the same as a cell membrane
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate
Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.
The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
Sofia’s favorite meal is breakfast, and she is careful to include healthy components along with her favorite foods. She knows breakfast helps to keep her energy levels up until lunch. Sophia's digestive system helps her body get energy from food. How do the nutrients from food get to the body's cells? A. The nutrients are distributed by the digestive system to the parts of the body that need them. B. The nutrients are picked up and transported around the body by blood from the circulatory system. C. The nutrients are absorbed directly into the cells that need them. D. The circulatory system brings nutrients to the digestive system to be processed for the cells.
Answer: c
Explanation:because it needs cells I think…
The nutrients from the food get to the cells of the body by the action of two organ systems i.e. the digestive system and the circulatory system.
What is the role of the digestive system?The digestive system may be defined as a type of organ system that significantly deals with the breakdown of food substances into simpler components that can easily be consumed by the body.
According to the context of the question, the food that we eat reaches the stomach through the esophagus where multiple enzymes perform their roles. After the stomach, the food may be passed to the small intestine which is absorbed here and then the nutrients assimilate in the blood.
Through the blood, the nutrient can be transported around the body by blood from the circulatory system. Thus, the correct option for this question is B.

Energy pyhamids, otherwise known as trophic level diagrams, are used to represent the flow of
energy through an ecosystem. An organisms trophic level indicates the organism's position in
the sequence of energy transfers. The bottom, or base, of an energy pyramid is a position
always held by the producers and represents (by far) the largest percentage of biomass for
the food web. The need for such a large biomass of producers is to support the energy
needs for all the organisms at higher trophic levels. Draw and label an energy pyramid for the
following 1 hectare of farmland:
• 30,000,000 MJ of Sunlight (solar energy) reaches ground level during a 150-day growing
season
• 52,164 MJ of energy is stored in the soybeans grown on the hectare of land
1,645 MJ of energy is stored in edible beef by cattlewho eat the soybeans
From the total energy that reaches the ground, 1% is used by producers. The energy transference in the trophic web follows the 10% rule, in which each level uses 10% of the energy stored by the anterior level.
---------------------------------------
Only 1% of the total solar energy that reaches the ground is used by producers, who occupy the first trophic level. From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment. At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The progressive reduction of energy determines the number of trophic levels (4 or 5).If 30,000,000 MJ of Sunlight (solar energy) reaches ground, then only 30,000 MJ can be absorbed by primary producers.
5,216.4 MJ from 52,164 MJ of energy stored in the soybeans, are used by cattle.
1,645 MJ of energy is stored in edible beef by cattle who eat the soybeans.
164.5 MJ of this energy is tranferred to the following trophic level.

which of these are the repeating units that form DNA molecules?
a. fatty acids
b.nucleotides
c.amino acids
d.chromosomes
Answer:
d.chromosomes
Explanation:
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins called histones which, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation

d: Neurotransmitter molecules bind to receptors in the postsynaptic cell.
e: A voltage change occurs in the postsynaptic cell.
Answer: hi im brain bot
im not sure i know this one im stumped
Explanation:
The event occurs as nerve impulse reaches the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell and voltage change occurs in the postsynaptic cell. A nerve impulse begins in the postsynaptic cell. The correct option is C.
What is synaptic transmission?The metabolic pathway by which a neuron interacts with a target cell across a synapse is known as synaptic transmission.
Chemical synaptic transmission is characterized by the release of a neurotransmitter from the presynaptic neuron and the binding of the neurotransmitter to specific post-synaptic receptors.
Synaptic transmission is the process by which a nerve impulse (action potential) travels from the presynaptic neuron to the post-synaptic neuron across the synaptic gap. An action potential is an electrical impulse that travels down the axon of a neuron.
As the nerve impulse arrives at the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell, causing voltage changes in the cell. and finally nerve impulse begins in the postsynaptic cell.
Thus, the correct option is C.

Can a virus cause a change in your DNA?
Please answer this don’t just take the points please I need help
Answer:
Yes , when viruses infect us, they can embed small chunks of their genetic material in our DNA. Although infrequent, the incorporation of this material into the human genome has been occurring for millions of years. As a result of this ongoing process, viral genetic material comprises nearly 10 percent of the modern human genome. Over time, the vast majority of viral invaders populating our genome have mutated to the point that they no longer lead to active infections. But, as scientists funded by the National Institutes of Health have demonstrated, they are not entirely dormant.
Explanation:
Answer:
Viruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome. Recombination occurs when co infecting viruses exchange genetic information, creating a novel virus.
