Answer:
A
Explanation:
The removal of a species can reduce the food source of another species, which can cause that species to slowly die out, where other animals that consume the dying species start dying out... ect.
So it decreases the biodiversity which can mess with populations.
If the species is a herbivore, it could cause the plants that are eaten by that herbivore to get out of control in population, which can fight for sunlight and resources with other species causing ecosystem collapse.
In an ecosystem, the removal of a species can decrease the stability. Thus, option A is correct.
What are the biotic factors of an ecosystem ?Biotic factors are the basic unit of ecosystem where the living beings interact with each other and their environment.
There are two components of an ecosystem such as biotic and abiotic components, include distribution of energy in our environment.
Biotic components can be classified into autotrophs, heterotrophs and decomposers based on mode of nutrition.
Autotrophs are producer such as plants as they produce food through the process of photosynthesis.
Heterotrophs are the consumer depend on producer for their nutrient, which is further classified into three categories.
Primary consumers are herbivores rely on producers for food while secondary consumers depend on primary consumers. They can be carnivores or omnivores.
Tertiary consumers depend on secondary consumers for food. some quaternary consumers are also seen in some food chains.
Decomposers include saprophytes such as fungi and bacteria which lie on decaying organic matter and essential for the ecosystem
Hence, option A is correct.

A biology student looked through a microscope and observed an Elodea cell in a drop of water and illustrated it in diagram A. He added a 10% hypertonic salt solution to the slide. He then observed the cell and illustrated the change in diagram B. What caused the change in the appearance of the cell after the salt solution was added?
More water flowed into the cell than out of the cell.
More salt flowed into the cell than out of the cell.
Lass salt flowed into the cell than out of the cell.
More water flowed out of the cell than into the cell.
Answer:
There are no diagrams in this question, however, it can be answered.
More water flowed out of the cell than into the cell.
Explanation:
According to this question, a biology student added 10% hypertonic salt solution to an Elodea cell in a drop of water. The student illustrated the changes observed in diagrams A and B. Based on the principles of OSMOSIS, which is the movement of water from a region of lower solute concentration to a region of higher solute concentration, water will flow out of the cell.
Since the solution outside the Elodea cell has more solute solute/salt concentration, water will be move down the concentration gradient from the cell into the extracellular solution. Hence, more water flowed out of the cell than into the cell.

Fat and ATP are different molecules that can both be described as molecules that store
energy. Compare the functions of these molecules in terms of energy storage.
A) O ATP molecules are made when where there is an excess amount of energy,
while fat molecules are used immediately.
B) O ATP molecules are used for long-term storage, while fat is used for
immediate energy
C) O Fat molecules are stable and can be stored for a long time, while ATP is not.
D) O Fat molecules are unstable and can be stored short-term, while ATP
molecules are stable and stored long term.
Answer:
C) Fat molecules are stable and can be stored for a long time, while ATP is not.
Explanation:
ATP is short-term energy, and fat is long-term energy and is used when when there is no more energy. Fat molecules are also highly stable because of the many covalent bonds
Answer:
C, i think
Explanation:
ATP is short term storage due to the fact that it is produced rapidly and used up just as fast in cells. Fat is long term, usually when there is no energy, fat is burnt up (during exercise is the most common) and used for energy
You conduct a voltage clamp experiment in which you hold the presynaptic terminal of a glutamatergic neuron (a neuron that releases glutamate) at 0 mV. When you treat the terminal with TTX, an inward current is recorded. Which ion and ion channels are responsible for the current you observe? Group of answer choices Calcium; ligand-gated non-specific cation channels Sodium; ligand-gated non-specific cation channels Calcium; voltage-gated calcium channels Sodium; voltage-gated sodium channels Potassium; voltage-gated potassium channels
Answer:
Calcium; voltage-gated calcium channels
Explanation:
Voltage-dependent calcium channels represent a group of voltage-gated ion channels and they are recognized to be primary mediators of calcium entry induced by depolarization. These channels are localized in the membrane of excitable cells such as, for example, neuron cells. The potential difference across the membrane of neuron cells without physiological activity is named resting membrane potential. When there is no action potential, voltage-dependent calcium channels are normally closed.

Answer:
ATP and NADPH are used to energy for the production of the Calvin cycle. Once their energy is released, they revert back to ADP and NADP+ and can be reused again.
Explanation:
ATP and NADPH are energy carriers that can be used to power chemical reactions. Once they have energized cellular processes, they become their 'low energy' form of ADP and NADP+. Later, they can reform ATP and NADPH to power more reactions

The difference between solstice and equinox is:
A. During the equinox the solar energy falls on the equator allowing all of Earth to receive equal amount of energy and during the solstice the solar energy falls on the tropics allowing them to receive the largest amount of energy.
B. During the equinox the Earth receives the largest amount of energy in the north pole and not during the solstice.
C. During the solstice the solar energy falls on the equator making all of Earth to receive equal amount of energy and during the equinox the solar energy falls on the tropics making them receive the largest amount of energy.
D. There is no difference they mean the same thing.
The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth's orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it's at the closest distance from the equator.
In this section write a short paragraph about photosynthesis using the following words in a meaningful way ; Photosynthesis, water, roots, glucose, leaves, sunlight, carbon dioxide, stomata
Answer:
Photosythesis is the process of which plants make oxygen and also gulcose. This process happens when the plants uses their roots to taken in water in the ground and also anchor themselves in the ground. The stomata in the leaves take in carbon dioxide and the sunlight and using theses materials the plants create glucose and oxygen we breath.

Explanation:
The trp operon encodes the genes required to synthesize tryptophan. This operon is regulated by a feedback loop in which tryptophan binds to a transcriptional regulator leading to a change in gene expression from the operon. This is most likely an example of__________. a. inducible gene expression b. repressible gene expression c. constitutive gene expression d. post-translational regulation of gene expression
Answer:
The correct answer is option b. "repressible gene expression".
Explanation:
The trp operon is a classic example of a repressible gene expression. The trp operon controls the biosynthesis of tryptophan from an initial precursor by encoding five genes that translate to three enzymes. These enzymes act as regulators and tryptophan itself acts as the final regulator. Tryptophan inhibits its own production when it binds to the transcription regulator, therefore it is an example of a repressible gene expression.

What is trail?Researchers gather information, group volunteers according to broad characteristics, and compare changes over time.
Repeated trials are when researchers do a measurement multiple times - at least three, commonly five, but the more the better. When they measure something once, the chance that the number he get is accurate is much lower. But if researcher measure it several times, then he can take an average of those numbers and get a result that is much closer to the truth.
