The section of the cell membrane illustrates one method of cellular transport. Consider steps A, B and C. What transport mechanism is represented by the model?
What is the correct order for respiration?
A. Krebs cycle, electron transport chain, glycolysis
B. Glycolysis, electron transport chain, Krebs cycle
C. Glycolysis, Krebs cycle, electron transport chain
D. Krebs cycle, glycolysis, electron transport chain
Answer:
Its C :)
Explanation:
The correct order of cellular respiration is Glycolysis > Krebs cycle > electron transport chain, hence option C is correct.
What is cellular respiration?It is the cellular process through which cells get oxygen inside it and release carbon dioxide outside of it.
Cellular respiration is the metabolic process that starts with the degradation of metabolic products and ends with the complete oxidation of these products.
Glucose is oxidized via glycolysis and produces pyruvate as an end product of glycolysis, this pyruvate is further oxidized into the Krebs cycle and releases electrons for the synthesis of ATP.
Therefore, for correct order of cellular respiration inside the cell option C, Glycolysis, Krebs cycle, electron transport chain is correct.

Which of the following contain the genetic code?
1)carbohydrates
2)lipids
3)nucleic acids
4)proteins
Nucleic acids are the carriers of the genetic code. The molecules that carry and transmit genetic information in living things are called nucleic acids, specifically the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) families. Therefore, the correct option is C.
The fundamental genetic material, DNA, is located in the nucleus of cells, while RNA is involved in gene expression and protein synthesis. Sequences of nucleotides, the constituent parts of nucleic acids, contain the genetic code. Proteins, lipids, and carbohydrates all play important roles in many cellular processes and functions within an organism, but none of them directly contain the genetic code.
Therefore, the correct option is C.

There are many methods used to obtain energy for use in our daily lives. Some of these methods have possible environmental consequences to rivers, groundwater, and organisms. One type of pollution involves excess carbon dioxide being released into the air. Some of the carbon dioxide reacts with water to form acid rain. Which energy sources can release carbon dioxide and carbon monoxide waste into the atmosphere?
Answer: Coal,petroleum
Explanation:
he process that we call "burning" actually is chemical reactions with oxygen in the air. For the most part, the carbon combines with oxygen to form carbon dioxide (CO2), and the hydrogen combines with oxygen to form water vapor (H20).
Some of the carbon dioxide reacts with water to form acid rain, and the energy sources can release carbon dioxide and carbon monoxide waste into the atmosphere through the burning of fossil fuels, coal, oil, etc.
What is the significance of burning fossil fuels?Carbon dioxide, which is also considered a "greenhouse gas," and other greenhouse gases in the atmosphere trap heat from the sun but never let the heat pass through the earth's atmosphere and make the earth hot. This is caused by the combustion of fossil fuels and causes air pollution, which can be harmful to human health and the earth.
Hence, some of the carbon dioxide reacts with water to form acid rain, and the energy sources can release carbon dioxide and carbon monoxide waste into the atmosphere through the burning of fossil fuels, coal, oil, etc.

Hair color and eye color are examples of a person's
Hair color and eye color are examples of a person's phenotype, which are the observable traits of an organism influenced by their genetic makeup (genotype) and environmental factors.
Explanation:Hair color and eye color are examples of a person's phenotype. In biology, phenotype refers to the set of observable characteristics or traits of an organism that are produced by the interaction of genetics (genotype) and the environment. Characteristics such as hair color and eye color are determined by the genetic material (genotype) that an individual inherits from their parents, and these traits are expressed physically (phenotype).
For instance, hair gets its color from the pigment melanin, which is produced by melanocytes in the hair papilla. Different hair color results from differences in the type of melanin, which is genetically determined. Similarly, eye color is also a genetic trait, and it too can vary based on the genetics of the individual.
This genetic diversity among humans results in the vast range of observable physical characteristics we see, such as different hair colors, eye colors, and much more. These traits can also interact with our environmental influences in ways that further shape our physical expressions.

What role do predators play in maintaining the balance of an ecosystem?
A)
They ensure that the ecosystem is not stripped entirely of its vegetation.
B)
They ensure the transfer of energy from plants to the rest of the food web.
C)
They are primarily responsible for the transfer of nutrients to the plants.
D)
They are primarily responsible for the cross pollination of plants in the ecosystem.
The correct answer is - A) They ensure that the ecosystem is not stripped entirely of its vegetation.
The ecological pole of the predators is to maintain the balance between the herbivores and the vegetation. By being able to kill and eat large numbers of herbivores, the predators do not allow their numbers to grow over what is an optimum for the survival of the ecosystem.
If there's no predators, for only a very short time, the numbers of herbivores will grow significantly, to the point where pretty much all of the vegetation will be stripped, thus ending without food and dying out very quickly, as well as damaging almost all vegetation and contributing to its dying out.
Predators ensure the transfer of energy from plants to the rest of the food web. Therefore, the correct option is B.
By controlling the population of their prey species, predators play an important role in maintaining the balance of the ecosystem. To keep herbivore populations under control and avoid overgrazing or excessive plant consumption, predators eat them. As a result plant populations can grow and regenerate permanently.
Predators also aid in the movement of energy through the food chain. They eat herbivores, and plants are a source of energy for herbivorous animals. As we move up the trophic levels, this energy is transferred from plants to herbivores to carnivores. Predators control herbivore populations by ensuring that energy is effectively channeled and dispersed throughout the ecosystem.
Therefore, the correct option is B.

An aerobic activity is defined as one that _____ the heart rate and ____ the body's need for oxygen.
increases; decreasesincreases; increasesdecreases; decreasesdecreases; increases
Answer: increase, increase
The term aerobic literally means "with oxygen", and refers to the use of oxygen by muscles for generating energy. An aerobic activity will increase the rate of heat so that it can pump more oxygenated blood because of increase in muscle activity, the need of oxygen of body also increases.
Hence, an aerobic activity is defined as one that increases the heart rate and increases the body's need for oxygen.
