Answer:

need picture brahj, but I got u, when it moves from high concentration to an area of low concentration, a process called diffusion. its process of moving glucose across the cell membrane is called facilitated diffusion.

Explanation:

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.

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.

[tex]\sf{\overline{\underline{PHOTOSYNTHESIS }}}[/tex]

Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.Carbon dioxide, water and light are all needed for photosynthesis to take place.Photosynthesis happens in the leaves of a plant.

Answer:

True

Explanation:

The temperature can rise as high as 1500 C, the gas molecules are very far apart. This layer is completely cloudless and free of water vapour

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:

A downhill

Explanation:

A runoff happens when water drags sediment from a rock over a sloping terrain. Thus, water drags the eroded fragments of a rock in favor of gravity, pushing these fragments downwards. This is very common in mountainous and steep regions, without vegetation cover, where erosion caused by runoff is very high.

Answer:

1. Water evaporates from a lake

2. Water vapor condenses to form clouds

3. water falls as rain, snow, and sleet.

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.

Answer:

Trophic Level Definition. A trophic level is the group of organisms within an ecosystem which occupy the same level in a food chain.

Examples of Trophic Level. Primary producers, or ”autotrophs”, are organisms that produce biomass from inorganic compounds

Explanation:

Answer:

The correct answer is - protist.

Explanation:

Protist is a single-celled eukaryote that contains organelles. It is the last common ancestor of all animals as is consider as most primitive animal cells as it has no cell wall but contains the nucleus and other double-membrane organelles. The protists are the cell that distinguishes fungus, plant cells, and animal cells into these three different kingdoms.

Thus, the correct answer is - protist.

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.

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.

Chemical 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.

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.

Answer:

Extrachromosomal or cytoplasmic inheritance

Explanation:

Extrachromosomal or cytoplasmic inheritance refers to hereditability transmission controlled by cytoplasmic genes.

This form of inheritance lays in genes that are out of the nucleus. Information for some characters is placed in organelles in the cytoplasm, such as mitochondria and chloroplasts. These organelles have a well-defined portion of the total cellular genome.

Although mitochondrial inheritance is mostly maternal, recent studies have demonstrated that it might also be paternal.

Sperm cells hardly carry mitochondria, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this DNI, the whole progeny of the mutated woman will be affected, as they will get the mother´s mitochondria carrying the mutation. On the contrary, if there is a man affected by a disease caused by a mutation in mitochondrial DNI, non of their descendants will get the disease.

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."

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.

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.
