Which statement is true about
electrically charged particles?
A. neutrons are positive, electrons are negative
B. protons are negative, neutrons are positive
C. protons are positive, electrons are negative
Answer:
C
Explanation:
protons are positive neutrons are neutral and electrons are negative
In an electrically charged particles protons are positive and electrons are negative.
Neutron has a positive electrical charge?The charge on neutron is zero(no charge). The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another and so atoms are neutral. Protons have positive or negative?A proton carries a positive charge and an electron carries a negative charge.so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain.Learn more about electrical charge here: http://brainly.brainly.com/question/1487561

Give an example of central heating and of local heating.
Answer:
A central heating system provides warmth to the whole interior of a building from one point to ... Institutional heating systems (office buildings or schools, for example) can use low-grade, inexpensive
An alternative to district heating would be to build a small district heating plant together with your neighbours, which is known as local heating or joint heating. ... The local heating system also includes a network of pipes and a common boiler plant that delivers heat through the pipework to the single-family houses.

Explanation:
The diagram that represents the modelling of a full moon is : ( D ) Diagram 4
Full moonA Full moon occurs when the moon moves from its new moon position by 180°. At this new position, the sun ( light source ) ,earth and the moon forms a straight line.
During full moon the moon is completely illuminated when viewed from the Earth's position as well.
Hence we can conclude that the diagram that represents the modelling of a full moon is Diagram 4

Protozoan- A single-celled microscopic animal of a group of phyla of the kingdom Protista, such as an amoeba, flagellate, ciliate, or protozoan.
Pseudopod- A pseudopod or pseudopodium (plural: pseudopods or pseudopodia) is a temporary arm-like projection of a eukaryotic cell membrane that are developed in the direction of movement.
Pellicle- Pellicle (biology), a thin layer supporting the cell membrane in various protozoa. Pellicle mirror, a thin plastic membrane which may be used as a beam splitter or protective cover in optical systems.
Slime Mold- Any of a group (such as Myxomycetes) of organisms formerly held to be lower fungi but now often considered protists that exist vegetative in usually moist habitats as mobile plasmodia and reproduce by spores.
pls help!!! osmosis help needed!!
Answer:
1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic
Explanation:
1. Given the image, it shows there is 10% glucose outside the cell.
2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)
3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.
2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water outside the cell than in. So, yes, osmosis will occur.
3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).
3. The cell will swell, since water is getting moved in.
6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always swell, as water moves into it.

In dense forests, obtaining sunlight for plants can be tricky. Growing on the ground is not always effective for plants because there is not much sunlight hitting the ground. Orchids are epiphytes, or plants that grow on other plants. They grow on branches of trees high up in the canopy. They get more sunlight and have more access to pollinators up in the high branches. Orchids lay their roots on the bark of a tree and obtain nutrients and water from their surrounding environment.
In a short answer, identify and describe the type of symbiotic relationship between orchids and the forest trees, and explain the effect of this interaction on each species involved.
Explanation:
The symbiotic relationship between orchids and trees is called commensalism, which means the orchid and tree host depend on eachother to survive.. The orchid provides the tree with sunlight, (nutrients created by sun- exposure).
the tree provides a solid base for the orchid to climb up the tree, they are dependent on eachother for survival...
The type of symbiotic relationship between orchids and forest trees is commensalism.
What is commensalism?Commensalism is a relationship in which one species benefits while the other is neither helped nor harmed. In this case, orchids benefit from the elevated position and access to sunlight provided by the trees, while the trees are neither helped nor harmed.
The effect of this interaction on orchids is that they are able to thrive in a challenging environment where they would not otherwise survive. The effect on forest trees is neutral, as the orchids do not harm or compete with them for resources. However, the presence of orchids on the tree bark may attract pollinators or other organisms, which could potentially benefit the trees indirectly.

Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.
Which of the following stages of photosynthesis involves carbon fixation, reduction reactions, and the ribulose 1,5-bisphosphate regeneration?
photoreduction
light-independent reaction
light-dependent reaction
first stage photosynthesis
Answer:
light-independent reaction
Explanation:
Photosynthesis, which is a unique metabolic process where plants synthesize their food (glucose) in the presence of sunlight, occurs in two stages namely: light dependent stage and light-independent stage.
The light independent stage is also known as dark stage because it does not require light to occur. It occurs in the stroma of the chloroplast where ATP and NADPH are used to fix carbon into the production of glucose. This stage involves three major processes:
- Carbon fixation of CO2
- Reduction reactions of G3P
- Regeneration of ribulose 1,5-bisphosphate (RUBP).

Explanation:
protein is the element responsible for building up of cells and the nucleic acid is embedded in the cell, so protein builds the whole cell including the nucleic acids.. the nucleic acid is also packed by histones which is a proteinous structure. both are important because, in the cell all organelles require protein for their growth and likewise the encoding of the genetic information carrier
