Which type of isolation is being described: Yellow butterflies breed during the summer season while red butterflies breed during the winter season, because of this, they cannot interbreed

temporal isolation

geographic isolation

behavioral isolation

Answer:

small plants ad animals tend to habit coral reefs because the sharp coral protects the animals from sharks and other predators. It also works as a ecosystem because every animal works together to provide for each other. I can t your anymore but that is the main idea of what coral does. if you can see if you can reword it into more sentences. How this helps!

Answer:

it is accepted that cells contain DNA in chromosomes and RNA in the nucleus and cytoplasm, but only in the modern cell theory. the classical cell theory does not include this. but using either classical or modern theory, it is false that all cells have DNA surrounded by a nucleus.

Answer:

Respiration

Respiration:- It is the process by which food (glucose) is broken down in the cells of the body with the help of oxygen to release energy. Since respiration takes place in the cells of the body, it is called cellular respiration.

Explanation:

The charge of Fe in Fe₂O₃ is +3.

Let's consider the equation for the thermite reaction:

Fe₂O₃ + 2 Al ⇒ Al₂O₃ + 2 Fe

One of the reactants is ferric oxide, we can calculate the charge of Fe in Fe₂O₃ considering that:

The charge of Fe in Fe₂O₃ is:

[tex]2Fe+3O = 0\\2Fe+3(-2)= 0\\Fe=+3[/tex]

The charge of Fe in Fe₂O₃ is +3.

A chemical formula is obtained from the number of atoms in a compound.

Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.

For instance, phosphorus trichloride contains one atom of phosphorus and three atoms of chlorine hence I would place a 1 in the box for P and 3 in the box for Cl.

The nucleus

Explanation:

This organelle gives all the info. Without it, the cell will die. It's like a human is alive without a brain.

Answer:

1. D (In population genetics, gene flow is the transfer of genetic material from one population to another.)

2. C (Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed. When there are few copies of an allele, the effect of genetic drift is larger, and when there are many copies the effect is smaller.).

3. A  and also E (Individuals with inherited characteristics that allow them to best compete for limited resources will survive and have more offspring than those individuals with variations that are less able to compete. Because characteristics are inherited, these traits will be better represented in the next generation.)

4. D (Gene flow can increase fitness but if it happens in another environment, it decreases the adaptability. If alleles are advantageous, the offsprings' inheritance increases.

5. B (Mutations are the main source of alleles)

Answer:

Fulgurites, commonly known as "fossilized lightning", are natural tubes, clumps, or masses of sintered, vitrified, and/or fused soil, sand, rock, organic debris and other sediments that sometimes form when lightning discharges into ground.

Answer: njnjnjnjinjinjnjinjinjnjnjnjnjnj

Ecological succession occurs in stages and permits a habitat to allow new species to grow in number as the habitat undergoes change. Thus C is the correct option.

Ecological succession is defined as the process through which the mix of species and habitat in an area changes over time.  Gradually these communities replace one another until a climax community like a mature forest is reached, or until a disturbance, like a fire, occurs.

There are two major types of ecological succession namely primary succession and secondary succession. Primary succession occurs when a new patch of land is formed or exposed for the first time.

Secondary succession occurs when a climax community or intermediate community is impacted by a disturbance.

The answer is A. RNA is single stranded and DNA is double stranded

Hope this helps!!

Answer:

Answer below! : )

Explanation:

Explain 1) The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. The dependent variable is the variable being tested and measured in an experiment, and is dependent on the independent variable. 2) Testing only one variable at a time lets you analyze the results of your experiment to see how much a single change affected the result. If you're testing two variables at a time, you won't be able to tell which variable was responsible for the result. 3) The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is "controlled" or held constant in the control group 4) Not sure about this one sorry! 5) hypothesizing, observing, and experimenting. 6) This rule says that where you have one situation that leads to an effect, and another which does not, and the only difference is the presence of a single factor in the first situation, we can infer this factor as the cause of the effect. 7) No matter how carefully observations and experiments are performed, it cannot be ensured that every possible factor is the same in every observation. 8)  Munsell Charts are used to provide standard descriptions and names of color. 9) Nitrogen, phosphorus, and potassium. 10) Water table, also called groundwater table, is the upper level of an underground surface in which the soil or rocks are permanently saturated with water. 11) Humus significantly affects the bulk density of soil and contributes to its retention of moisture and nutrients. 12) Texture refers to the size of the particles that make up the soil. The terms sand, silt, and clay refer to the relative sizes of the soil particles. The combined portions of sand, silt, and clay in a soil determine its textural classification. 13) The main difference between sand silt and clay is their particle size. Sand particles are larger in size while clay particles are extremely fine, and silt particles are somewhere in between sand and clay particles. Sand, silt, and clay are the main mineral particles in the soil that affect its texture 14) Mineral matter is derived from the constituents of the parent material.  Organic matter.  The nature and abundance of iron.  Moisture content. 15) In some mineral soils aluminum can be dissolved at pH levels below 5.0 becoming toxic to plant growth. Soil pH may also affect the availability of plant nutrients. Nutrients are most available to plants in the optimum 5.5 to 7.0 range. 16) Phosphorus is essential for cell division and growth and promotes plant maturation. 17) Aspect of soil porosity concerns the oxygen found within these pore spaces. All plants need oxygen for respiration, so well-aerated soil is important for growing crops. 18) The ground above the water table may be wet to a certain degree, but it does not stay saturated. The dirt and rock in this unsaturated zone contain air and some water and support the vegetation on the Earth.

Answer: Photosynthesis, Decomposition, Respiration and Combustion

Explanation:

The cycling of carbon in the carbon cycle is released from animals and plants in form of carbon dioxide through respiration or released by decomposition and internalized by a process called photosynthesis in plants.

It initiates when a plant dies and gets buried turning into fossil fuel. This fossil fuel is burnt by humans converting most of the carbon into carbon dioxide.

Carbon dioxide is added to the atmosphere by respiration of animals and the plants. Plants again use this carbon dioxide to perform photosynthesis thus quickly adding it to their bodies from where the cycle continues.

Answer:

Active faults are structure along which we expect displacement to occur. By definition, since a shallow earthquake is a process that produces displacement across a fault, all shallow earthquakes occur on active faults. Inactive faults are structures that we can identify, but which do no have earthquakes.
