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.

Solar radiation is a broad word for the electromagnetic radiation that the sun emits. It is also sometimes referred to as the solar resource or just sunshine. A multitude of devices can be used to collect solar radiation and transform it into useful forms of energy, such as heat and electricity.
How much of the Sun do we actually see?Sunlight at Earth's surface is roughly 42 to 43 percent visible (400 to 700 nm), 52 to 55 percent infrared (above 700 nm), and 3 to 5 percent ultraviolet in terms of energy (below 400 nm).The Sun always emits the same amount of energy. Insolation refers to the incoming solar radiation. Seventy percent of solar energy makes it to the planet.99.8% of the mass in our solar system is found in the Sun. Everything, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion light-years away, is kept in place by its gravitational attraction.What would occur if our distance from the Sun increased by 10%?More radiation, ultraviolet rays, heat, and other rays would be directed at our atmosphere. It would be impossible to live. According to my projection, the global average temperature would increase from 16 C to 65 C. (149 Fahrenheit). This would be high enough to prevent most life from existing, yet low enough to prevent water from boiling.The solar system itself, the Sun Between 99.8 and 99.9 percent of the mass of the solar system is found in the Sun. The remaining matter is distributed among the planets and their satellites, asteroids, comets, and the gas and dust that surrounds our star.To learn more about Solar radiation, Refer:

true or false? a haploid organism has one pair of homologous chromosomes.
Answers
Answer:
False
Explanation:
A haploid has one SET of homologous chromosomes
It is false that a haploid organism has one pair of homologous chromosomes.
What are haploid organisms?When an organism's cells only have one set of chromosomes, the organism is said to be haploid.
All organisms that reproduce are diploid (having two sets of chromosomes, one from each parent). Only the egg and sperm cells in humans are haploid.
Male ants, bees, and wasps are haploid organisms because they develop from unfertilized haploid eggs, whereas females (workers and queens) are diploid, making their system haplodiploid. The majority of animals are diploid.
The term "diploid" describes how many complete sets of chromosomes there are in each cell of an organism: diploid cells have two entire sets.
On the other hand, haploid organisms only have one complete set of chromosomes. Throughout meiosis and sporadically in mitosis, chromosome sets can change.
Thus, the given statement is false.

Diffusion is the net movement of molecules through a semipermeable membrane based on a concentration gradient.
What is diffusion?
Diffusion has the net movement of molecules through a semipermeable membrane. It goes from high concentration to low concentration. Osmosis has been the process in which molecules of the solvent pass via a semipermeable membrane from a lower concentrations to higher concentration or from less concentrated solution to high concentrated solution. In the process of osmosis movement of water takes place.
There are mainly three types of osmosis and these are hypertonic, hypotonic, and isotonic. The process of osmosis is passive transport as water moves from low solute concentration to high solute concentration.
Osmosis has been also known as diffusion of water or solvent via a membrane which allows only selective substance to go across the channel. The process of osmosis does not require ATP because it is a passive process.
Therefore, Diffusion is the net movement of molecules through a semipermeable membrane based on a concentration gradient.

You would use a test cross to determine the next generation
Explanation:
If you crossed two plants from the F2 generation, test cross procedure you should follow to determine the genotypes of the next generation.
What is a test cross?Another important tool created by Gregor Mendel is the test cross. A test cross is a genetic experiment that involves crossing a homozygous recessive organism having a dominant phenotype with an unidentified genotype (and phenotype).
A test cross is a tool for investigating an organism's genetic makeup. The test cross was initially employed as an experimental mating test to identify the genotype's allele composition.
Therefore, to determine the genotypes, the test cross gets its name from the fact that it can tell whether a person has a homozygous dominant or heterozygous dominant trait.

(c) Make a claim about the most immediate effect on the fused B-cancer cells if the fused cells are transferred to a growth medium that lacks a source of nitrogen.
Answers
Answer:
CLAIM: IF THE FUSED B CANCER CELLS ARE GROWN IN A MEDIUM THAT DOES NOT CONTAIN NITROGEN SOURCE, THE CELLS WILL STOP SYNTHESIZING PROTEINS AND THEIR LIFE SPAN WILL BE GREATLY REDUCED
Explanation:
The growth medium that was used to reproduce the fused cancer B cells contains nitrogenous compounds that serves as source of nitrogen for the production of nitrogenous bases of DNA, If the nitrogen source is removed, the DNA in the nucleus of the white blood cell will lack adenine and guanine, which are necessary for the synthesis of DNA molecules.
2. Nitrogen is an integral part of DNA and protein. Nitrogen is needed to produce nitrogenous bases that are found in DNA. The DNA molecule is the one that initiate and direct the synthesis of protein in living cells.
In the fused B cancer cells, DNA must be produced, so that the dividing cancerous cells can continue their uncontrolled division, this will keep the cells alive. Nitrogen is also needed for the continuous synthesis of the special protein that the fused B cell is producing.
Thus, if nitrogen source is removed from the growth medium used for the cultivation of fused B cells, then the cells will stop synthesizing protein, their life span will be greatly reduced and they will eventually die out.
