Edith Widder: Glowing life in an underwater world
1. On her first open-ocean dive in the Santa Barbara Channel, Widder says she dove down to 880 feet and turned off her lights. Explain why she did this and how she described what she saw?
2. If you happen to be on a ship and go to use the bathroom at night without turning on the light, why does Widder explain you might think you are having a “religious experience”?
3. Why are most people who are studying bioluminescence today focused mainly on the chemistry behind it? What does the Nobel Prize have to do with this?
4. What makes bioluminescence an important factor of survival for so many animals? Provide one example Widder gives to explain this.
5. Why is Widder dissatisfied with the way we explore the ocean? What are the two main ways we learn about what lives in the ocean that she describes?
6. How does Widder tell the difference between the species she observes in the deep ocean? Give an example of a species she identifies based on this observation.

Answers

Answer 1

Answer:

1. She turned off the lights because she knew that she would see a phenomenon of animals making light called bioluminescence. She described that she was totally unprepared for how much there was and how spectacular it was. She saw chains of jellyfish that were pumping out a lot of light; and puffs and billows of what looked like luminous blue smoke and sparks of blue light from the thrusters.

2. The head on ships which are the toilets on ships are flushed with unfilltered seawater that often has bioluminescent plankton on it. So, if you stagger into the haed late at night and you're toilet-hugging sick, that you forget to turn on the light, you my think that you're having a religious experience.

3. They are focusing on the chemistry because these chemicals have proved so incredibly valuable for developing antibacterial agents, cancer fighting drugs, testing for the presence of life on Mars, detecting pollutants in our waters which is how it is used at ORCA. In 2008, the Nobel Prize in Chemistry was awarded for work done on a molecule called green fluorescent protein that was isolated from the bioluminescent chemistry of a jellyfish, and it has been equated to the invention of the microscope, in terms of the impact that it has had on cell biology and genetic engineering.

4. What makes it important for the survival of many animals is for the animals that are trying to avoid predators by staying in the darkness, light can still be very useful for the three basic things that animals have to do to survive: and that's find food, attract a mate and avoid being eaten.

5. The primary ways that we know about what lives in the ocean is we go out and drag nets behind ships. The other primary way is we go down with submersibles and remote-operated vehicles. Doing that there are bright lights and thrusters that disturbs the animals and makes then go away.

6. She was able to tell the difference between the species by the types of flashes they produced like the big explosions, sparks, are from a little comb jelly.

Within a cave environment, bat waste products, called guano, are decomposed by organisms such as fungi and bacteria. These are then eaten by
creatures such as flatworms. Larger animals like salamanders eat flatworms. Which correctly represents the energy flow described?
A. Fungi - Bacteria - Salamanders - Guano
B. Bats - Guano - Flatworms - Salamanders
C. Salamanders - Fungi - Bacteria - Flatworms
D. Guano - Bacteria - Flatworms - Salamanders

Answers

Answer:

D

Explanation:

The correctly represents the energy flow described in the given case is - D. Guano - Bacteria - Flatworms - Salamanders

Energy flow

Energy flow is the movement of energy that is transferred from one trophic level to another trophic level but does not revert back. It is always unidirectional and it follows II nd law of thermodynamics.

In the given food chain, energy is transferred from waste products called guano by a bat which does not involve a bat directly, thus it starts from guano, and energy moves to bacteria and then flatworms and ultimately to the salamanders.

Based on the energy flow between trophic levels in an energy pyramid how much energy would be expected to be found at the secondary consumer level in this pyramid

Answers

Answer:

100J of energy is transferred to the secondary consumers

Explanation:

According to the second law of thermodynamics, energy transfer from one trophic level to another is not usually a 100% transfer of energy. This is because the organisms at each trophic level use energy derived from food substances to carry out its activities.

Only about 10% of the energy obtained at each trophic level is transferred to the next trophic level.

This implies that only about 1000J of energy is transferred to the primary consumers and 100J of energy is transferred to the secondary consumers.

Granite takes much longer to form than basalt. How will the size of the crystals in granite be different from the size of the crystals in basalt?

Answers

Answer:

The size of the crystals in granite will be different from the size of the crystals in basalt depending on how they are formed and how they are cooled which determines the nature of the crystals they produce. Granite takes a much longer time to form than basalt because granite takes a very long time to cool down since it is intrusive giving minerals to be well-formed and producing a bigger size of crystals with individual mineral grains that are can be seen without the need for bigger magnification. While basalt crystals are much smaller as the crystals form very quickly because the magma comes out of the earth and cools quickly giving rise to fine-grained minerals.

Explanation:

Granite and basalt are both igneous rocks.

Granite takes a longer time to cool as it hardens under the earth's surface causing the delay in cooling while basalt takes a shorter time to cool as it hardens above the earth's surface.

A system of intra-continental ridges passes through Kenya from north to south, including the Great Rift Valley.

It is a portion of the Gregory Rift, the eastern branch of the East African Rift, which extends northward into Ethiopia from where it begins in Tanzania to the south. The Arabian, Nubian, and Somalian plates' interactions resulted in the formation of the "Kenyan Dome," a geographical upwelling.

It was once thought to be a component of the "Great Rift Valley," which stretched from Syria to Madagascar. The valley's majority was once part of the Rift Valley Province.

How does the nucleus, cell membrane, and ribosomes work together?

Answers

Answer:

Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.

OR

In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome. The newly made subunits are transported out through the nuclear pores to the cytoplasm, where they can do their job.

The nucleolus inside the nucleus produces ribosome components, which are synthesized just outside of the nucleus form ribosomes.

The spindle then sends mRNA towards the ribosomes, which is used to code for protein synthesis.

Other organs in the cell, including the mitochondria and lysosomes, are surrounded by lipid membranes that isolate them from other components in the cell.

which is true regarding the process of meiosis I?
A) chromosome Number is reduced from diploid to haploid
B) sister chromatids in a cell undergoing are always identical
C) Most homologue pairs do not have any crossovers during prophase I
D) sister chromatids separate to opposite ends of the cell

Answers

Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)

Explanation:

In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.

Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.

A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:

--> the chromosomes replicate once and

--> the nucleus and cell duplicate ( divide equally) twice.

As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.

Delta and Alpha are the same distance from the equator, and they are both near the ocean. Using the information in the map, how does the air temperature of Delta compare to the air temperature of Alpha? Why?

Answers

The image of this question is missing, so i have attached it.

Answer:

Explained below.

Explanation:

From the image attached, we can deduce that;

- The air temperature of Delta will be warmer than Alpha.

- The reason is because the wind will push ocean water that's turning and following the coasts and thereby making energy to be transferred from the ocean to the air at Delta and also from the air to the ocean at Alpha.

Answer:

I am doing the same test as you, so it is D. warmer than Alpha. The winds push ocean water that turns and follows the coasts. A lot of energy is transferred from the ocean to the air at Delta, and only a little energy is transferred from the ocean to the air at Alpha.

But taxonomists, as organized as they maybe, have no idea how many species Earth has. Nor can they even provide aneducated guess. Although reporting over 16,000 new species every year,taxonomists still cannot predict how many more are undiscovered.In total, taxonomists have categorized and listed 1.2 million species on Earth. At thispoint, you would think scientists should be able to use the information they havegathered to make good predictions about how many species an ecosystem cansupport. This would help them make better predictions about how many species areleft to identify. So far, however, the guesses seem to vary so greatly that it seemsthere is no good theory for making a prediction.One of the main problems is that most of the places that seem to have a lot ofdiverse species are in places that are hard to get to. One such place is the ocean,where scientists believe some 80 percent of Earth's creatures are hiding at depthstoo deep for us to study. In addition, many of the planet's most diverse areas are inremote places with few taxonomists.Despite all the unknowns, scientists have agreed that there are between five and 15million species left to discover on Earth.
