Kenneth and Catherine Lohmann of the University of North Carolina explored the orientation or direction-finding abilities of loggerhead sea turtle hatchlings under varying magnetic conditions. Hatchlings were placed in a tank of water in a laboratory either in the natural magnetic field of the earth OR in a reversed magnetic field in which north and south were flipped. The researchers then measured the direction that the hatchlings swam. The experiments were carried out in the dark and at night since that is when most newly hatched turtles migrate from their sandy nests into the ocean. The results of the Lohmanns' experiments are most likely to be considered credible if Group of answer choices a great deal of time had been spent collecting hatchlings and running experiments. the experiments were funded by a government grant. the results were published in a peer-reviewed journal. the Lohmanns are famous scientists.

Answers

Answer 1

Answer:

the results were published in a peer-reviewed journal.

Explanation:

When the results of any study or a research is published in a well renowned and a peer reviewed journal, then the study is considered to be credible and authentic and is accepted by the intellectual society.

In the context, two young scientists are performing an experiment on the direction finding or the orientation finding abilities of the loggerhead sea turtle which are hatching under the varying magnetic fields.

The finding of these experiment or the result will be considered credible only when the results of the experiment will be published in a peer reviewed journal.

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.

method of using desert land for agriculture
b.
the process of turning arable land into deserts
C.
drying up of stream beds and lakes
d.
the expansion of current deserts land areas

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).

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:

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.

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. It provides carbon dioxyde, and must be constant in the four scenarios to avoid an effect on the results.

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.

Explanation:

G1 is the first stage of the cell cycle, and it is essential for cell growth.

Next, the S (Synthesis) phase occurs. This phase involves DNA synthesis to prepare the cell for division.

G2 is the next phase, and it involves preparing and growing the cell for mitosis.

Mitosis is the next stage, where the cell divides into 2.

Lastly, Cytokinesis occurs after mitosis, and it creates the two daughter cells.

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.

Why do oxygen levels drop sharply during eutrophication?

Answers

Explanation:

during eutrophication, there is a presence of excess algae in the water body. this causes an excess overconsumption of available organic materials by algae, causing the oxygen levels to reduce rapidly.

When the algae population grows rapidly, it may hinder sunlight from reaching other lifeforms and cause dissolved oxygen levels to fall.

What is eutrophication?

Eutrophication is the substantial increase in phosphorus, nitrogen, and other organic material in an ageing aquatic environment such as a lake.

As the amount of organic material that can be subdivided into nutrients increases, so does the efficiency or fertility of such an ecosystem.

When the algae population grows rapidly, it may prevent sunshine from reaching other organisms and cause dissolved oxygen levels to fall.

The primary environmental impacts of eutrophication are an increase in suspended particles caused by extensive macroalgal blooms, a decrease in water clarity, and an increase in precipitation rate, which has resulted in the destruction of benthic habitat due to shading of submerged vegetation.

Thus, this way, oxygen levels drop sharply during eutrophication.

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.

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.

Answers

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.
