Which organelle supplies the cell with energy?
a. ribosome
b. cytoplasm
c. nucleus
d. mitochondrion?
Answer: Mitochondria.
Explanation:
Mitochondria is a double membrane bound organelle found in the cytoplasm of the cell. The main function of mitochondria is to produce energy currency ATP (adenosine triphosphate) which is used by every cell of the body to perform metabolic activities.
The energy production takes place by the process known as cellular respiration in the presence of oxygen by the breakdown of glucose.
The mitochondrion is the part of the cell that supplies energy. It is often referred to as the 'powerhouse of the cell' as it turns glucose into ATP, the cell's energy-carrying molecule via cellular respiration.
Explanation:The organelle that supplies the cell with energy is the mitochondrion. Among your options, ribosome is responsible for the synthesis of proteins, the cytoplasm hosts various cell processes and the nucleus contains the cell's genetic material. However, it's the mitochondrion, often described as the powerhouse of the cell, that provides the energy. It does this by breaking down glucose into ATP (adenosine triphosphate) through a process called cellular respiration. ATP is the molecule that carries energy within cells and is vital for cell functions.

The large ground finch obtains food by cracking seeds. What is its short, strong beak an example of?
Final answer:
The large ground finch's short, strong beak is an adaptation resulting from natural selection and adaptive radiation, allowing it to crack hard seeds effectively.
Explanation:
The short, strong beak of the large ground finch Geospiza magnirostris is an example of adaptive radiation and natural selection. Through processes described by Charles Darwin, finches on the Galápagos Islands have adapted their beaks over generations to exploit different food sources effectively. For the large ground finch, its beak has evolved to crack open hard seeds, making it thicker and stronger compared to finches that eat other types of food, like insects or nectar.
Observations by researchers such as Peter and Rosemary Grant provide evidence for this evolutionary change. They reported that during a drought, finches with larger beaks could eat more types of seeds, and hence were more likely to survive. Their offspring also tended to have larger beaks, showing evolution by natural selection.

c. DNA does not replicate
d. the cytoplasm and DNA are divided between two new cells.
The prokaryotic cell cycle is different from the eukaryotic cell cycle because in the prokaryotic cell cycle cell division does not involve the division of the cell nucleus.
What do you mean by Cell cycle?The cell cycle may be defined as the process a cell goes through each time it divides. The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies.
Prokaryotic cell lacks a nucleus and well-defined cell organelles. Due to the deficient nucleus, a prokaryotic cell never involves the nucleus in its division.
Therefore, the prokaryotic cell cycle is different from the eukaryotic cell cycle because in the prokaryotic cell cycle cell division does not involve the division of the cell nucleus.

Trichodesmium is a nitrogen-fixing cyanobacteria. Why might this cyanobacteria be important to other organisms in nitrogen-poor waters?
They convert atmospheric nitrogen (N2) to organic compounds including ammonia (NH3).
They convert inorganic nitrogen to ammonia (NH3) in the ocean.
They convert organic nitrogen compounds to into other nitrogen compounds. They convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere.
Answer: They convert atmospheric nitrogen (N₂) to organic compounds including ammonia (NH₃).
Trichodesmium is cyanobacteria which converts atmospheric nitrogen into ammonia which is then used by other organisms present in the nitrogen poor water. They are found in the nutrient poor tropical and sub tropical ocean waters .They account for approximately half of the nitrogen fixation in marine system all over the world.
Final answer:
Trichodesmium is important to other organisms in nitrogen-poor waters because it converts atmospheric nitrogen into ammonia, providing an essential nutrient that supports marine life and maintains the nitrogen cycle in these regions.
Explanation:
Trichodesmium is a nitrogen-fixing cyanobacteria that plays a critical role in marine ecosystems, particularly in nitrogen-poor waters. As a diazotroph, this colonial cyanobacteria can convert atmospheric nitrogen (N₂), which is abundant but unusable by most organisms, into ammonia (NH₃), a form of nitrogen that is readily available for use by plants and phytoplankton. This process is crucial for supporting life in regions of the ocean where inorganic sources of nitrogen are scarce, as it helps maintain the nitrogen cycle and supports the base of the food web.
In nitrogen-poor waters, organisms depend on nitrogen fixers like Trichodesmium to contribute to the primary productivity of the ecosystem. The fixed nitrogen provided by Trichodesmium is essential for the synthesis of amino acids, nucleic acids, and other vital organic compounds within marine organisms. Therefore, without such diazotrophic cyanobacteria, many marine ecosystems would struggle to thrive due to the lack of accessible nitrogen.
Hence, the correct answer is they convert atmospheric nitrogen (N2) to organic compounds including ammonia (NH3).

When NADH passes its electrons into the Electron Transport System, NADH is chemically:
reduced
enzymized
hydrolysed
oxidized
Answer:
Option D, oxidized
Explanation:
The NADH gets oxidised when it passes its electrons into the Electron Transport System
Oxidization is a process in which one element or compound loses its electron to other chemical element or compound thereby itself getting oxidised and reducing the other one (the one who gains the electron).
Here in the electron transport system, the NADH loses or donates its electron to the Electron Transport System thus chemically it gets oxidized.
Hence, option D is correct
A------------ is each step in a food chain that demonstrates the transfer of energy.
A trophic level is each step in a food chain that demonstrates the transfer of energy.
A trophic level is any feeding level in a food chain through which energy in the form of food is transferred in an ecosystem. A food chain contains five main trophic levels which are; (i) primary producers (autotrophs; plants and algae), (ii) primary consumers (herbivores), (iii) Secondary consumers (carnivores and omnivores), (iv) Tertiary consumers (carnivores and omnivores) and (v) Apex predators.
A 'trophic level' refers to each step in a food chain, showcasing the energy transfer from one organism to another. The energy transfer starts with the Sun and travels through different organisms, from producers to consumers, providing an understanding of a food chain.
Explanation:In the field of Biology, each step in a food chain, demonstrating the transfer of energy from one organism to another, is referred to as a trophic level. This energy transfer begins with the Sun, which provides energy to producers like plants. Herbivores, or primary consumers, consume these plants and gain energy.
Then, carnivores, or secondary and tertiary consumers, eat these herbivores and other carnivores to get energy. The energy transfer continues through each trophic level, demonstrating the concept of a food chain.

Answer:
The answer are:
- Respiration.
- Photosynthesis.
Explanation:
Respiration allows plants to produce the necessary energy to perform their vital functions. Respiration of plants requires an exchange of gases between the plant and the environment, since when breathing, plants take oxygen from the environment and expel carbon dioxide (CO2) to the environment. Photosynthesis is a process that plants carry out to manufacture their own food from various elements that they find in their environment, such as sunlight, carbon dioxide and water, where inorganic materials become organic. This process serves for the development and growth of the plant.What forms whenever a large body of air over land or water does not move for a long period of time?

What is an example of eukaryotic gene regulation? Why is gene regulation necessary or advantageous?
Eukaryotic gene regulation, exemplified by the control of transcription initiation, allows organisms to adapt to environmental changes and use resources efficiently, leading to evolutionary advantages.
Eukaryotic Gene Regulation
An example of eukaryotic gene regulation involves the control over the start of transcription, where a multitude of regulatory proteins and elements play a role. One key reason why gene regulation is necessary is because it allows cells to respond to environmental changes and allocate resources efficiently. Moreover, advantageous gene regulation can lead to better survival and reproductive success, providing an evolutionary benefit.
In eukaryotes, the regulation of gene expression is often far more complex than in prokaryotes, involving multiple mechanisms such as the presence of enhancers, which are distant DNA regions that loop back to interact with a gene's promoter. For instance, human cells must coordinate the activity of approximately 25,000 genes without the use of multigene operons, which adds layers of complexity to how genes are turned on and off. This complexity allows for a greater diversity in gene expression, which can be essential for the development and function of multicellular organisms.
The need for gene regulation is exemplified by changes in gene expression, which can have evolutionary consequences. Evolution can act on gene regulation patterns, and changes in these patterns can lead to adaptations that enhance an organism's fitness in changing environments.
