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)

Answers

Answer 1

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

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.

2.1explain the body's hormonal response to dehydration​

Answers

Answer:

Vasopressin, a hormon is secreted by pituitary gland which is response to dehydration , causes kidney to excrete less water.

The body's hormonal response to the dehydration is the action of vasopressin in the kidney. The vasopressin decrease the work of the kidney and it leads to decrease the amount of water secreted by the kidney to save water in the body.

What is dehydration?

Dehydration is a condition where there is less water present in the body. There are many reasons of dehydration, like drinking less water or diarrhea. All reactions of the body work by water. So loss of water severely affect the body.

The hormonal response to dehydration is the release of vasopressin by the pituitary gland of the body. The vasopressin saves water from the body to help body fighting with dehydration.  It makes the kidney to filter less water.

Thus, the activation of vasopressin in the kidney causes the body's hormonal reaction to dehydration. Vasopressin lessens the kidney's workload, which causes a reduction in the amount of water the kidney secretes to conserve the body's water supply.

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.

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.

Answers

Answer:

first 4, then 2, then 1, and lastly 3

Explanation:

First, RNA polymerase binds to the promoter region of a gene on the DNA and initiates transcription. Transcription is the process by which we get mRNA (coding RNA) which is used as a template for protein synthesis. Then, in transcription, the resulting mRNA undergoes modification and maturation. This  involves removal of introns, addition of 3'-poly-A tail and 5'-cap. Introns are sequences that do not code for protein and are hence removed. The structure that removes introns is the spliceosome. Thirdly, mature mRNA travels to the cytoplasm. Ribosome (composed of rRNA) binds to mRNA and tRNA to start the process of protein synthesis. The process of formation of protein is called translation. Lastly, the primary structure of protein may undergo folding to form a tertiary structure.

Answers

Complete question:

Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.

Group of answer choices

A) behavioral . . . prezygotic

B) mechanical . . . postzygotic

C) temporal . . . prezygotic

D) gametic . . . postzygotic

Answer:

A) behavioral . . . prezygotic

Explanation:

The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.

There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.

Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.

There are different types of reproductive barriers.

Pre-copulatory o pre-ziygotic:

Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.  

Postzygotic mechanisms or barriers include

Hybrid inviability,   Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.

Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.

During an experiment, the controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.  

In this experiment,

The independent variable → presence/absence of light reaching the plant. The researcher regulates the amount of light by using different elements such as the bucket, lamp, flashlight, and natural light. The dependent variable → oxygen production through which the researcher measures the photosynthesis rate. The controlled variableSodium  bicarbonate  solution.
