Answer:
Photosynthesis is a process through which plants and other organisms transform light energy into chemical energy, which is then released to power the organism's activities through cellular respiration.
Which type of selection is also known as diversifying selection because it tends to favor the survival of two or more different phenotypes in a heterogeneous environment
Answer:
Disruptive selection.
Explanation:
Disruptive selection is also called diversifying selection because it favor the survival of two or more different types of phenotypes in a particular environment. Disruptive selection describes changes in population in which extreme values for a trait are favored whereas the intermediate values are less favored. Due to the increase the variance of the trait which leads to the division of population into two distinct groups.
The theory of natural selection states that
Answer:
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Explanation:
Consider a neuron in which the Cl- concentration inside of the cell is 15 mM and outside of the cell is 140 mM. Once the ions flow and reach an equilibrium, approximately what will be the concentration of Cl- inside of the cell
Answer:
The correct answer is - negative.
Explanation:
Cl- ion is more concentrated outside of the cell, as it is given 140 and therefore it will try to move to the inside of the given cell as inside ion concentration is low.
At last, the diffusive force will be get to equilibrium due to an electrostatic force pulling Cl- ions back out of the cell. At this equilibrium point, Cl- ions will moved towards to the the neuron and cause the membrane potential to be more negative.

During intense exercise, the muscle cells require constant supply of ATPs but the supply of oxygen is low. In that case - the muscle cells of the person will switch from which to which pathway?
Answer:
Aerobic to lactic acid fermentation pathway
Explanation:
ATP, which is the usable form of energy in living cells, is obtained via a process called RESPIRATION. However, aerobic respiration requires a constant supply of oxygen to occur. Hence, during an intense exercise where the supply of oxygen is low, the muscle cell has to switch from the respiration pathway that requires oxygen to one that doesn't.
Fermentation is a kind of cellular respiration that does not require oxygen to occur. In the muscle cells of animals (humans inclusive), lactic acid is the product of the fermentation process, hence, it is called LACTIC ACID FERMENTATION. This means that the muscle cells, in a low supply of oxygen, will switch from AEROBIC to LACTIC ACID fermentation pathway.

What is the name of the strategy that combines two plant proteins (grains and beans) to get all the essential amino acids
Answer:
Protein combining
Explanation:
The strategy involving the combination of two plant proteins to get all the essential amino acids is referred to as protein combining.
The practice of protein combining is common among vegans due to the general belief that a single plant-based protein does not contain all the necessary amino acids for the body. Thus, one would need to combine 2 plant-based proteins in order to get all the essential amino acids for adequate health.
After nervous stimulation stops, calcium ions returning to the sarcoplasmic reticulum prevent ACh in the synaptic cleft from continuing to stimulate contraction True False
Answer:
False.
Explanation:
Neurotransmitter release occurs from the nervous terminal or varicosities in the neuronal axon. When an action potential reaches the nervous terminal, the neurotransmitter is released by exocytose. The molecule binds to its receptor in the postsynaptic neuron, triggering an answer. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic response. To stop this process the neurotransmitter must be taken out from the synaptic space. There are two mechanisms by which the neurotransmitter can be eliminated:
• Enzymatic degradation/deactivation: There are specific enzymes in the synaptic space, which are in charge of inactivating the neurotransmitter by breaking or degrading it. The enzyme acetylcholinesterase prevents ACh from continuing to stimulate contraction.
• Reuptake: Receptors located in the presynaptic membrane can capture de molecule to store it back in new vesicles for posterior use. These transporters are active transport proteins that easily recognize the neurotransmitter.

Answer:
Increased exponentially
Industrial carbon emission
Warm the planet
Explanation:
The rapid increase in global CO2 in the 21st century has raised concerns over the lingering effect of global climate change which could result due to the exponential increase in CO2 emission at this time. This rise in global atmospheric CO2 has been observed to have a positive relationship with the level of industrial carbon emission. The rise in emission of industrial carbon has been tipped to be responsible for the exponential rise in global atmospheric CO2. CO2 is a form of green house gas responsible for warming the planet.

Given their size and complexity, biological molecules such as carbohydrates, proteins, lipids, and nucleic acids can also be referred to as ____________.
Answer:
This question lacks options, the options are;
A. Enlarged molecules
B. Macromolecules
C. Inorganic molecules
The answer is B
Explanation:
As mentioned in this question, carbohydrates, proteins, lipids, and nucleic acids are the basic biomolecules found in nature. They are all polymeric substances, hence, are made up of smaller units called monomers.
Asides from being biomolecules, these four molecules are also referred to as MACROMOLECULES based on their large size and complex nature. Macromolecules are molecules that are relatively large in size composing of an aggregate of monomer. Hence, these biomolecules are macromolecules.
What is a variegated leaf
Answer:
The term, "variegated" is applied to a flower or, more often, a leaf that has more than one color. Most often, it will be two-toned (that is, bi-colored). Often this will mean the foliage is blotched, striped, or bordered with a lighter color than that on the rest of it (or vice versa). The term is also applied more broadly to a whole plant that bears such leaves or blossoms. The corresponding noun for this definition is "variegation."
how is the structure of endoplasmic reticulum related to its function?
Answer:
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.

Which of the following factors affecting population growth is density
independent?
A. Competition
B. Disease
C. Natural disaster
D. Predation
C. Natural disaster is a density-independent factor affecting population growth. Density-independent factors are those that affect the population irrespective of the population size or density.
How Natural disasters reduce population sizes?Natural disasters such as floods, hurricanes, earthquakes, and wildfires can reduce population sizes regardless of how many individuals were present in the population before the disaster occurred. The other factors listed - competition, disease, and predation - are all density-dependent factors, which means that they become more significant as the population size or density increases.
Competition is an example of a density-dependent factor, as it increases as the population size increases. As more individuals compete for limited resources such as food, water, and shelter, the rate of population growth slows down.
Disease is another density-dependent factor, as it spreads more easily in crowded populations where individuals are in close contact with one another.
On the other hand, natural disasters such as floods, hurricanes, and wildfires are examples of density-independent factors. These events can affect a population regardless of its size, and they can cause significant decreases in population size.
Predation can be both a density-dependent and density-independent factor. In some cases, predation can increase as the population size increases, making it a density-dependent factor. However, predators can also reduce the population size through random hunting or selective hunting of weaker individuals, making it a density-independent factor.
Understanding the factors that affect population growth is important for predicting and managing population sizes in both natural and human-made ecosystems.

Explanation:
A Scientist discovers a chemical that she thinks might be a potential treatment for a certain type of cancer cell. In order to test her hypothesis, the scientist treats one plate of cancerous cells with the newly discovered chemical, and leaves another plate of cancerous cells untreated. After 7 days, the scientist measures the number of living cells in each plate. The scientist finds that the cells treated with the chemical have a lower survival rate than cells left untreated. The scientist further observes that the substance has an effect on the Rough endoplasmic reticulum (RER). How might disabling the rough ER potentially hurt the cancerous cells? Be specific in your answer. What is the dependent variable? What is the independent variable?
Answer:
Affecting the ER causes alteration in cell homeostasis and eventual death.Independent variable: Drug or chemicalDependent variable: Cancer cells survival.Explanation:
Hypothesis ⇒ A chemical ⇒ might be a potential treatment for cancer cells.
Experiment:
Treated ⇒ One plate of cancerous cells with the new chemicalUntreated ⇒ Another plate of cancerous cells with no chemical7 days later ⇒ the number of cells in each plate
Results:
Cells treated with the chemical have a lower survival rate than cells left untreated.
Treated plate ⇒ fewer cellsUntreated plate ⇒ more cellsChemical affects the Rough endoplasmic reticulum (RER)
----------------------------------------------------------------------------------------------------------
The endoplasmic reticulum is in charge of many cellular functions, such as protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction.
When the synthesizing protein gets in the Rough endoplasmic reticulum, it continues its building in the organelle. Finally, the protein suffers folding and the initial stages of glycosylation.
Once the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex for their final association with carbohydrates. Finally, protein leaves the Golgi complex and goes to its final destiny.
Any alteration in the intracellular environment
inevitably affects the organelle and its functions. When the organelle is not properly working, proteins synthesis is affected and, consequently, all the cellular activities. The affected cell homeostasis might be so altered that the cell ends dying.
If the drug affects the ER by altering its environment or directly affecting it, the organelle will fail to perform its functions, and the cell will eventually dye.

The independent and the dependent variables are the two principal factors needed in an experiment.
Independent variable: Refers to all the variables in an experiment that provoke a response in another variable. The independent variable changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter.
In the exposed example, the independent variable is the drug that affects the cancer cells. The researcher decides to apply it or not, and the concentrations in which the drug is.
Dependent variable: Refers to the variable that reacts to the changes produced in the independent variable. Depending on how the independent variable is modified, the dependent variable change. It is usually identified by the letter Y.
In the exposed example cell survival is the dependent variable. Cancer cells respond to the presence/absence of the chemical, and might differently respond to the varying concentration of the drug.

This is very common in mountainous and steep regions, without vegetation cover, where erosion caused by runoff is very high.
A metric that measures the decline in population sizes, shrinkage of species, and geographic range is ________.
Answer: Living Planet Index
Explanation:
The Living Planet Index is a survey measure of global biodiversity status based on the population abundance of vertebrate species in terrestrial, freshwater and marine habitats. We have to consider that a population is defined as a species within a geographical area. It is used as a source of information to identify threats at the population level for each species on Planet Earth.
With this analysis, an overall decline of about 60 percent in population size has been seen between 1970 and 2014. The decline in species populations is particularly greatest in the tropics, with South America and Central America suffering the most dramatic decline. The numbers of freshwater species have also declined dramatically. However, measuring biodiversity (all the varieties of life that can be found on Earth and the relationships between them) is complex, so the index should consider indicators to measure changes in species distribution, extinction risk and changes in community composition.
The goal of the Living Planet Index is to achieve and promote global conservation of animals and their habitats.
