A plant with variegated (two-coloured) leaves was left in the sun for several hours. A piece of one of its leaves were then detached (removed) and tested for sugar.
Explain, as fully as you can, why the yellow region of the leaf had not produced sugar. (5 marks)
Answer:
The yellow leaf was not exposed to the sun so it can't produce sugar.
Explanation:
The yellow region of the leaf didn't produce sugar because it wasn't exposed to sunlight. Part of the leaf was exposed to the sun, thus this leaf produced sugar, while the yellow part of the leaf did not because it was not exposed to the sunlight.
This is the range of habitats in a region
Answer: species range
Explanation:
A species range is an area where a particular species can be found during its lifetime. Species ranges include areas where individuals or communities may migrate or hibernate.

Answer:
Explanation:
In carbon cycle, carbon is just being recycled from one thing to other. For example, here we can see that green plants are part of carbon cycle because they go through photosynthesis, a process through with plants take in Carbon dioxide. The carbon is then used to make molecules such as carbohydrates and proteins, and are part of structural support to plant cells as well. Now when this organism (the organism could be an animal or plant) dies, the bacteria decomposes the organic matter (the dead body) and through respiration the carbon dioxide is released back into the environment.
Another way carbon recycles is that animals, plants, and microorganisms all respire (breathe out) CO2 thus carbon dioxide is added to the environment.
Answer:
Hi.. Ok lets start with animals.....Animals give out carbon dioxide during the breathing process and obtain oxygen.The carbon dioxide given out by the animals is obtained by green plants which use it on addition to chlorophyll water and light energy to make their own food.When animals die they decompose to form micro organisms...The micro organisms add nutrients to the soil thus promoting the growth of plants.I think it is the foodchain

B.
Both plants and animals release carbon dioxide into the atmosphere during cellular respiration.
C.
Dead organisms and waste products do not play any role within the carbon cycle.
Factories do not emit any amount of carbon dioxide into the atmosphere.
Answer: The answer would be B
Explanation: All plants and animals release at least some amount of co2 into the atmosphere during cellular respiration
Both plants and animals release carbon dioxide into the atmosphere during cellular respiration can be determined based on the Carbon cycle model. So, the correct option is B.
What is Carbon cycle?The exchange and recycling of carbon in the Earth's biosphere, lithosphere, hydrosphere and atmosphere is known as the carbon cycle. All living things contain the element carbon, which is also an important component of many important compounds such as proteins, lipids, and carbohydrates.
Photosynthesis, respiration, combustion and weathering are just a few of the different processes that make up the carbon cycle. Plants use photosynthesis to take up atmospheric carbon dioxide and convert it into organic molecules. Plants and other organisms then use these molecules as a source of energy.
Therefore, the correct option is B.

Answer:
Iron
Explanation:
The earth's core is mostly made up of iron and has a radius of about 760 miles. It is surrounded by a liquid outer core composed of a nickel-iron alloy.
Which molecular formula corresponds to this model of a chemical compound? (black = carbon; red = oxygen; white = hydrogen) A ball-and-stick model has two black balls bonded to each other at center, with single-bonded red balls bonded to white balls above left and below right, and double-bonded red balls above right and below left. C2(OH)4 C2H2O4 C2H4O2 C4H2O2
Answer:
C2H2O4
Explanation:
The molecular formula can be derived through the below analysis.
Two black balls (C) bonded to each other at the center = C2
Single-bonded red balls (O) bonded to white balls (H) above left and below right = (OH)2 = O2H2
Double-bonded red balls above right and below left = O2
Adding the three together = C2 + O2H2 + O2 = C2H2O4
The correct answer is C2H2O4

What did you include in your response? Medications can be tested on cell cultures instead of being injected into patients unnecessarily. Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells. Specific treatments that are shown to fight the growth of cancer cells in the culture can be used on patients. Cultures are safer to use than injections of unneeded medications into patients.
Answer:
The statements are correct.
Explanation:
Cell culture is a technique widely used in molecular biology where cell lines are grown in controlled conditions, thus allowing to make experiments and to test compounds that may result useful to treat diverse diseases, including cancer.
Immortalized cell lines are characterized for their ability to proliferate indefinitely which are derived from oncogenic tissues. In cancer research, these lines are used as models to test different drugs and to study cellular mechanisms associated with cancer progression including, among others, proliferation, invasiveness, vascularization, etc. In addition, the mechanisms associated with the death of cancer cells such as, for instance, apoptosis, may also be studied by using immortalized lines.
How often should observations be made in a simulation of natural selection??
Answer:
A minimum of 3 observations will produce reproducible results
Explanation:
Often, when simulations are carried out to observe for natural selection, it will be safe to conduct >3 observations to reduce the likelihood of errors. Errors could affect the reproducibility of the results which researchers will not want to compromise. The models ( for example the physical natural selection simulation or the virtual natural selection simulation methods) that are used provide for more observations to be made to ensure more accurate results and interpretations are obtained.
what chemical substances must be provided for aerobic respiration to take place inside the cell
Answer:
Oxygen
Explanation:
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.

Experiment: Water Properties: Why were the results with just water so much different than the trials with the detergent?
Answer:
Explanation:
Water is a universal solvent whose molecule are joined together with a force of attraction. Its surface tension is hidden between bonds. When washing, soap is added for easy penetration of water molecule and to decrease the surface tension. This then allow the water to move freely round the object been washed.
Detergent aid the distribution of water, of water is used alone without the detergent then the surface area of water will not be reduced to all even spread. But, if detergent is added the tension is reduced and a better result is obtained.

Explain the unique bonding properties of carbon.
Carbon , hence overcomes this difficulty by sharing its four valance electrons with other atoms of carbon or with atoms of other elements.
What do you mean by valence electrons?A valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed.
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table.
