Answer:
The answers are:
carrier proteins → charged amino acid
Carrier proteins are transmembrane proteins for the facilitated diffusion of charged amino acids across plasma membranes.
osmosis → water molecule
A type of passive transport, osmosis is the diffusion of water molecules in and out of cells.
active transport → calcium moves from low concentration to high concentration
This is the movement of substances across membranes against concentration gradient.
simple diffusion → oxygen
Oxygen molecules enter through membrane by simple diffusion from an area of high to low concentration.
exocytosis → proteins from the Golgi apparatus
This process of exocytosis is used by cells to release particles that has been packaged by the golgi bodies.
Explanation: Boom
Carrier Proteins is Charged Amino Acid, Osmosis implies to Water Molecule, Active Transport - Calcium moves from low concentration to high concentration, Simple Diffusion - Oxygen, and Exocytosis - Protein from the Golgi Apparatus.
In assisted diffusion, a type of transport in which charged amino acids or other molecules bind to particular carrier proteins in order to traverse the cell membrane, carrier proteins are involved.
The passage of charged amino acids through the membrane is aided by this mechanism.
Osmosis is the flow of water molecules over a membrane that is selectively permeable, caused by variations in solute concentrations.
The movement of substances against a gradient of concentration, usually from a region of lower concentration to one of greater concentration, is referred to as active transport.
In this instance, calcium ions are actively moved utilising ATP energy from low concentration to high concentration areas.
Simple diffusion is the gradient-driven passive migration of molecules from a region of higher concentration to a region of lower concentration.
Due to their small size and nonpolarity, oxygen molecules can freely diffuse through the cell membrane through simple diffusion.
Exocytosis is the process through which cells discharge big molecules, such proteins, to the exterior of the cell from the Golgi apparatus.
The proteins are contained in vesicles that join the cell membrane and discharge their contents outside of the body.
Thus, charged amino acid transport is facilitated by carrier proteins, water molecules are moved by osmosis, calcium is moved against its concentration gradient by active transport, oxygen is moved along its concentration gradient by simple diffusion, and proteins are released from the Golgi apparatus through exocytosis.

The founder effect occurs when Multiple Choice large groups of individuals leave their home population and establish new settlements, mating only among themselves. small groups of individuals leave their home population and establish new settlements, mating only among themselves. many members of a population die, resulting in a great loss of genetic diversity. many members of a population reproduce causing too much genetic diversity within the population. small groups of individuals leave their home population and join established settlements, and mating with natives.
Answers
Answer: small groups of individuals leave their home population and establish new settlements, mating only among themselves.
Explanation:
The founder effect is what happens when a small group of individuals leave their home population in order to establish new settlements. They will then mate only amongst themselves and colonize the area without mixing with the natives.
As a result of the founder effect, there is less genetic variation in the new population than in the home one because the smaller number of individuals who left would not possibly be able to carry all the genes in the home population. The only genes that would be passed on are those of the small individuals.

All of the answers probably contribute to the muscle weakness.
Answers
Answer:
The correct answer is ''loss of acetylcholine receptors in the end-plate membrane.''
Explanation:
Myasthenia gravis represents a human autoimmune disease. The neuromuscular junction abnormalities that occur in this disease are due to antibody-mediated processes. A reduction in the number of functional acetylcholine receptors on the postsynaptic membrane was established to contribute to the physiological abnormalities of myasthenia gravis. The reduction in receptors is due to immunological alterations directed against the acetylcholine receptor. Normally, when acetylcholine binds to its receptor, it opens allowing the rapid entry of cations, especially sodium. With this, the depolarization of the postsynaptic region of the muscle fiber occurs. Although acetylcholine is normally released in myasthenia gravis, it is not capable of causing an action potential in the muscle sufficient to initiate or weaken contraction. In patients with myasthenia gravis, failure to activate muscles is responsible for myasthenic fatigue. Most patients have elevated serum titers of antireceptor antibodies, which in turn accelerate receptor degradation.

Which of the following is NOT true of enzyme activity? a. enzyme shape may change during catalysis b. the active site on an enzyme orients its substrate molecules, therby promoting interaction of their reactive parts c. all enzymes have an active site where substrates are temporarily bound d. each enzyme can catalyze a wide variety of different reactions
Answers
Answer:
D. Each enzyme can catalyze a wide variety of different reactions
Explanation:
Each enzyme can only catalyze a few, specific types of reactions.
Since enzymes and substrates are very specific to one another, enzymes cannot catalyze a wide variety of reactions.
If a substrate is not the correct one that fits in the enzyme's active site, a reaction will not occur.
So, each enzyme can only assist in a few reactions.
The correct answer is D. Each enzyme can catalyze a wide variety of different reactions

Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)
Answers
Answer:
The correct answer is - Biwalves and sponges.
Explanation:
Suspension feeders are the organisms that depend on, for the dietary needs or nutriton, materials suspended in the water. The materials that are suspended are living organisms such as phytoplankton and zooplankton.
Biwalves and sponges are suspended or filter feeders and not predators like other organisms so providing copepods will not complete their food requirement and they will starve to death.
The correct answer is - Biwalves and sponges.

1.Explain what makes a scientific experiment reliable. Be sure to include at least three reasons to support your answer.
2.During research, why is it important to use peer reviewed evidence when collecting background information during a scientific investigation?
Answers
An experiment is reliable when its repetition produce always the same result. In science, peer review is fundamental because this process ensures that there is not misleading data that may lead to erroneous results.
In sciences, reliability is a term used to evaluate the quality of research. Reliability refers to the probability that an experiment or result is correct, thereby preventing and mitigating failures over time.
An experiment whose successive repetitions conduct the same result is 100% reliable.
Three examples of reliability in science: the same measurement of the size of the leg of a spider. the observation of the same behavior of birds populations on different days and at different times of the day. the same byproducts from a given chemical reaction when an experiment is repeated two or more times.
Peer review is the most widely accepted process used to validate scientific data. This process (peer review) is fundamental to facilitate the growth of scientific knowledge.
During peer review, independent scientists assess the originality, reliability, and significance of a scientific work before its publication.

d.

Answers
Answer:
B
Explanation:
I believe it's B because desertification is the process of land being turned into deserts due to many factors like animal grazing.
Desertification means the process of turning arable land into deserts, which is the second option. Desertification is a process in which agricultural land is affected the most, resulting in the land having fewer nutrients.
What is desertification?Desertification is a process in which arable land is affected, and as a result, crop production is reduced. Desertification is the result of many factors, such as climate change, rapid urbanization, population growth, global warming, etc. The less water, nutrients, and microbes there are in the soil, the more likely it is that the land will become a desert.
Microbes in the soil become extinct as a result of climate change, causing crop patterns to shift and more land to become desert. Global warming causes temperatures to rise and many species to become extinct, exacerbating the problem.
Hence, desertification means the process of turning arable land into deserts, which is the second option (b).

Answers
Answer:
The correct answer is ''arises from the greater splanchnic nerve''
Explanation:
The greater splanchnic nerve or great adrenal nerve, originates in the thoracic sympathetic chain from vertebral levels T5 to T9 (T10). It runs over the bodies of the thoracic vertebrae and as it descends it becomes more anterior. It enters the abdomen crossing the diaphragmatic pillar and ends at the celiac plexus. The upper part of each celiac ganglion continues with the greater splanchnic nerve. The collateral or prevertebral ganglia innervate the abdominal and pelvic organs and viscera. The celiac ganglion receives preganglionic fibers from T5 to T12 and innervates the stomach, liver, pancreas, gallbladder, small intestine, spleen, and kidneys.

Show the importance of the inheritance of how steps in meiosis change chromosomes through one of these processes.
Background: Meiosis is the process used by sexually reproducing organisms and is made up of eight sub-steps or phases. During meiosis, chromosomes can be changed through crossing over and nondisjunction leading to changes in the inherited traits of offspring.
Answers
Meiosis is the process that occurs in sexually reproducing organisms in the sex cells of male and female organisms.
Variation occurs in an organism due to the process of crossing over which only occurs in meiosis in which the chromosomes between non-sister chromatids exchanged. Meiosis also causes genetic variation due to the process of recombination so in inheritance, meiosis has great importance and impact on the shape and structure of organism.
