Summarize the role
of organisms, including micro-
organisms, in maintaining the
equilibrium of a marine ecosys-
tem while a dead whale decays
on the ocean floor.
Answers
Answer:
The disturbance that causes the succession begins with a large whale dying and sinking to the bottom of the ocean floor. The whale carcass attracts scavengers and decomposers who eat the decaying meat.
Then, within a year, most of the whale's tissues have been eaten. The remainder of the carcass is then eaten by a much smaller number of fish. The decomposition of the whale's body will enrich the surrounding sediments with nutrients.
When only the skeleton is left, a third community moves in. Heterotrophic bacteria will begin to decompose the oils found inside whale bones. During this process, they will release chemical compounds that serve as energy sources for other bacteria. This chemosynthetic bacteria will also support a wide variety of nearby organisms living on the bones.
The decay of a dead whale on the ocean floor provides food and energy for a variety of organisms, which helps to maintain the equilibrium of the marine ecosystem.
When a whale dies, it sinks to the ocean floor and begins to decay. The decay process releases nutrients into the water, which attracts a variety of organisms, including bacteria, fungi, and worms. These organisms feed on the whale's carcass, breaking it down into smaller and smaller pieces.
As the whale decomposes, it releases carbon dioxide and other nutrients into the water. These nutrients are then used by other organisms in the ecosystem, such as algae and phytoplankton. The algae and phytoplankton use the nutrients to photosynthesize, which produces oxygen. The oxygen is then released into the water, which helps to support other life in the ecosystem.
The decay of a dead whale also provides a habitat for a variety of organisms. The whale's carcass creates a sheltered environment for small organisms, such as crabs and shrimp. These organisms provide food for larger organisms, such as fish and seabirds.
The decay of a dead whale is an important part of the marine ecosystem. It provides food and energy for a variety of organisms, which helps to maintain the equilibrium of the ecosystem. The decay process also releases nutrients into the water, which are then used by other organisms in the ecosystem.
Here are some additional details about the role of organisms in the decay of a dead whale:
Bacteria: Bacteria are the first organisms to colonize a dead whale. They break down the whale's carcass into smaller and smaller pieces.Fungi: Fungi also play a role in the decay of a dead whale. They break down the whale's carcass into even smaller pieces, releasing nutrients into the water.Worms: Worms are another important group of organisms that help to decompose a dead whale. They burrow into the whale's carcass, breaking it down into even smaller pieces.Algae: Algae and phytoplankton use the nutrients released by the decay of a dead whale to photosynthesize. This produces oxygen, which helps to support other life in the ecosystem.Fish: Fish are attracted to the carcass of a dead whale. They feed on the whale's flesh and bones, as well as on the smaller organisms that live on the carcass.Seabirds: Seabirds also feed on the carcass of a dead whale. They eat the whale's flesh and bones, as well as the smaller organisms that live on the carcass.The decay of a dead whale is a complex process that involves a variety of organisms. These organisms play an important role in maintaining the equilibrium of the marine ecosystem.

A) Pine trees need less water to do photosynthesis.
B) Pine trees produce twice as much glucose as deciduous trees.
C) Pine trees do not lose their leaves and can photosynthesize all year.
D) Pine trees get more sunlight than oak trees due to their darker color.
Answers
Answer:
C) Pine trees do not lose their leaves and can photosynthesize all year.
Explanation:
In cold-temperate and Arctic regions, however, evergreens are typically cone-bearing shrubs or trees (conifers), such as pines and firs. Many tropical species of broad-leaved blooming plants are evergreen. Thus, option C is correct.
What are features of pine trees?Pine trees may photosynthesize in the winter because they retain their needles all year long! Compared to trees that lose their leaves, this is a significant advantage.
Their leaves therefore stay green and stay attached for a longer period of time than their deciduous counterparts because they can preserve more water.
However, because of their tiny surface area, needles are not as effective at absorbing the sun's energy.
Therefore, Pine trees do not lose their leaves and can photosynthesize all year.

Design a controlled experiment to determine the effect of hot, dry air on head lice. In your experimental design, be sure to:
• state the hypothesis to be tested in the experiment [1]
• state one way the control group will be treated differently from the experimental group [1]
• state one result of the experiment that would support the hypothesis [1]
Answers
An experiment is carried out to answer a question. The hypothesis predicts what is expected to occur. Experimental and control groups are compared to analyze the results, supporting or not the hypothesis.
-----------------------------------------
BACKGROUND
When people are infested with head lice, it is recommended to wash their cloth and dry it with hot air over 53 or 54ºC for 5-30 minutes.
Head lice and eggs seem to die when exposed to those conditions by getting dehydrated.
SITUATION
We will assume that we work in a primary school and that students from the 3rth grade are being affected by this parasite.
We want to know if applying hot air to these students before entering the class will make a difference and help to control this problem.
So, we will propose an experiment to answer this question.
HYPOTHESIS
A hypothesis is a conjecture. A researcher hypothesizes to predict what is going on or what is expected to occur. The hypothesis is a claim of how it works a relation between two or more variables. Usually, it is written in the present time.
Hypothesis ⇒ Applying hot air to students' heads kills the head lice that students are carrying.
To evaluate the effect of hot air, we need to keep control of as many other variables as possible.
To do so, we asked students' families not to use other treatments on students' heads and to bathe them daily.
In this way, we were sure that all students
were equally affected by the parasite, took showers every day, and neither was using any other product that could affect the results.Our population was the 3rth grade students ⇒ 64 children ⇒ 30 girls + 34 boys.
Before the experiment, we separated the 3rth grade into two groups.
Group A ⇒ 32 students ⇒ 15 girls + 17 boys ⇒ Experimental groupGroup B ⇒ 32 students ⇒ 15 girls + 17 boys ⇒ Control group
→ Treatment
Each student from group A received hot air every day for one week before entering the class.
Hot air was 53ºC and was applied for 5 minutes.
→ Control
Each student from group B did not receive the treatment for one week before entering the class.
CONTROL GROUP
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
Individuals of the control group are selected from the same population as the treatment group.
*** These two groups are identical in all aspects except for the independent variable, which changes in the treatment group but remains constant in the control group. ***
The control group is Group B. The only difference between the control and the experimental group is that the first one did not receive the treatment. Every other aspect was equal for both groups.
The only way the control group was treated differently from the experimental group was that the control group did not received the treatment, while the experimental group did.
RESULTS
After one week, groups were compared to see if the hot air was effective in killing head lice.
When comparing the control and the experimental group, we could see that students from group A were free of parasites.
Students from group B were still affected by the head lice.
CONCLUSION
The results support the hypothesis. Hot air turned to be a great treatment for lice control.

What is protein?
Proteins are among the most prevalent organic molecules in biological systems and have a much wider range of structural and functional variations. Many thousands of proteins, each serving a different purpose, can be found in a single cell.
All proteins are composed of one or more chains of amino acids, despite the fact that their structures and activities differ substantially from one another.
In biological reactions, enzymes function as catalysts, accelerating the reactions. Each enzyme may distinguish between one or more substrates, or the molecules that act as the catalysts for the reactions they catalyze.
