Explanation:
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.
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.
The teacher was unaware of the difference between suspension feeding and predation. The teacher thought that providing live copepods (2 mm long) and feeder fish (2 cm long) would satisfy the dietary needs of all of the organisms. Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)
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.
The celiac ganglion ________. Group of answer choices is located near the base of the superior mesenteric artery arises from the greater splanchnic nerve projects postganglionic fibers that innervate the small intestine and the kidney and urinary bladder arises from the lesser splanchnic nerve arises from the lumbar splanchnic nerve
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.
Help!!!! Give a simple overview of the process of photosynthesis.
Answer:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil.
Explanation:
This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Which of the following is NOT true of the
muscular system?
A. They are connected to bones.
B. They allow voluntary movement.
C. They allow us to move.
D. They are connected by gap junctions.
The one that is not true regarding muscular system is that they are connected by gap junction. The correct option is D.
What is gap junction?Gap junctions are specialized intercellular connections that connect a wide variety of animal cell types.
They connect the cytoplasm of two cells directly, allowing molecules, ions, and electrical impulses to pass through a regulated gate between cells.
Location includes that the gap junctions can be found in a variety of locations throughout the body.
This includes epithelia (surface coverings of the body), nerves, cardiac (heart) muscle, and smooth muscle (such as that of the intestines). Their primary function is to coordinate the activity of neighboring cells.
Skeletal muscle cells lack gap junctions because they do not require them. Skeletal muscles are not made up of individual cells.
Thus, the correct option is D.

What causes an ionic bond to form between sodium and chlorine?
Answer:
The loss of an electron
Explanation:When sodium (Na) and chlorine (Cl) are combined, the sodium atoms each lose an electron, forming cations (Na+), and the chlorine atoms each gain an electron to form anions (Cl−
Answer:
"Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. ... If sodium can transfer it's "spare" electron to chlorine, both atoms will satisfy their full outer shell requirements, and an ionic bond will be formed."

Use the text to identify the sentences with evidence that matches the claim.
Claim 1 --> Tropical rainforests contain more biodiversity than all other biomes.
1) Biodiversity refers to the total number of different species of all kinds living in an area.
2) Tropical rainforests have many of the climate characteristics that organisms of different species need to grow, such as warm temperatures, plenty of rain, and many food sources.
3) There are large amounts of daily sunlight, which provides a great deal of energy to a variety of rainforest organisms.
4) Surprisingly, rain forest soil is very poor.
5) Due to the large amounts of rainfall, nutrients are leached out of the soil quickly.
6) Warm temperatures cause dead organisms to decay quickly, and the nutrients are then used by many different plants.

Isabel's first car had a manual stick shift. After many years of driving an automatic car, she needs to use her sister's car, which also has a stick
shift. Isabel takes a few minutes to get used to shifting gears. Which memory system Is she using to recall this information?
• A. episodic memory
O B. procedural memory
• C.
semantic memory
)D.
sensory memory
Answer:
Procedural memory
Explanation:
Isabel has to recall the information about using a manual stick shift. For this reason, she is using long-term, explicit, declarative and episodic memory system.
Human memory system can be broadly classified as: sensory memory, short-term memory and long-term memory.
Long-term memory is used to recall information. If the information are about facts, events and experiences then explicit, declarative and episodic memory helps to recall all information. This will help Isabel to recall all information about driving a car with a manual stick shift and she will be able to drive her sister's car.

Which of the following statements about active transport is true?
Molecules move down the concentration gradient.
ATP is not required to move molecules through the membrane.
ATP is formed as molecules pass through protein channels.
It results in a higher concentration of molecules on one side of the membrane.
Answer:
It results in a higher concentration of molecules on one side of the membrane.
Explanation:
Active transport is the transport of molecules up the concentration gradient. This means that molecules are going from low density to high density. This is the opposite of natural diffusion. So, it requires ATP to move the molecules this way. Diffusion normally occurs to maintain homeostasis and an equal amount of concentration on both sides of a membrane. But, with active transport, since molecules are moving up the gradient, the opposite happens and the concentrations are unequal.

When many nucleotides link together, they form a biomolecule responsible for storing genetic information called nucleic acids. Thus, the correct option is B.
What are Nucleotides?Nucleotides may be defined as the basic unit of the polynucleotide chain of nucleic acids such as DNA or RNA. Each nucleotide is composed of three components. They are as follows:
A nitrogenous base.A pentose sugar (ribose in the case of RNA, and deoxyribose in the case of DNA).A phosphate group.Nucleotides are the monomers of nucleic acids. Each nucleotide is joined together by covalent bonds known as phosphodiester linkage. This linkage is present between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar of next nucleotide.
Therefore, nucleic acids are formed when many nucleotides link together which are responsible for storing the genetic information.
