Why do most food chains only two, three or rarely ,four consumers after the green plant producer?
Answer:
It is rare to find food chains that have more than four or five links because the loss of energy limits the length of food chains. At each trophic level, most of the energy is lost through biological processes such as respiration or finding food
Explanation:
Answer:
Because so much energy is lost to life processes.
Explanation:
As you progress through each trophic, each organism on that level loses energy gained from the previous trophic. This is due to losing energy through wasted material (e.g. bones) and to life processes, 7 of which can be remembered by MRS GREN:
M ovement
R espiration
S ensitivity
G rowth
R eproduction
E xcretion
N utrition
This means that each time, energy is wasted and lost from the food chain. More than four trophics would result in so much energy being lost from the initial trophic (producer), that it would be largely pointless!

True
False
Use simply identification to classify organisms
Answer:
Living things are classified into groups that start out large and become more specific in a system of classification called taxonomy. Scientists classify living things at eight different levels: domain, kingdom, phylum, class, order, family, genus, and species.
Explanation:
Cell researchers are investigating the role of cyclins on mitosis and cell division. They notice that cyclins build up, cause the cell to progress through the cell cycle, then break down, thus ending the different stages of the cell cycle. A failure of the cell to break down which cyclin would most directly lead to increased cell division?
A) Cyclin A
B) Cyclin B
C) Cyclin D
D) Cyclin E
The inability of the cell to break down cyclin D would most directly lead to increased cell division.
What is cell division?Cell division is the process by which cells in the body divide their content and duplication of the chromosomes to produce new daughter cells.
In the cell cycle, proteins known as cyclins are required.
Cyclin D is required at the initiation and termination stage of cell division.
Therefore, based on the cell cycle diagram, inability of the cell to break down cyclin D would most directly lead to increased cell division.

Explain the use of oxytocin in labor inductoin in the case of obstructed labor
How does cytokinesis in plant cells differ from cytokinesis in animal cells?
animal cells form a cell plate
plant cells form a cell plate
plant cells go through the process in reverse
plant cells go through two rounds of cytokinesis while animal cells just do once
Answer:
During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast.

When a volcano erupts, particles of rock and ash are released into the atmosphere. After this, water droplets form around the rock and ash particles and fall to Earth as rain. The rainwater helps plants grow.
In this scenario, which spheres of Earth interact?
1.biosphere, cryosphere, hemisphere
2.cryosphere, geosphere, biosphere
3.geosphere, hydrosphere, biosphere
4.hydrosphere, cryosphere, geosphere
Answer:
When a volcano erupts particles of rock and ash are released into the atmosphere after this water droplets form around?
When a volcano erupts, particles of rock and ash are released into the atmosphere. After this, water droplets form around the rock and ash particles and fall to Earth as rain. The rainwater helps plants grow. Which scenario describes an interaction between two of Earth's spheres?
Explanation:
The spheres of Earth that interact in this scenario are the geosphere, hydrosphere, and biosphere.
The geosphere, which makes up the solid Earth, spews rock and ash particles into the atmosphere during a volcanic eruption. These ascenting particles come into contact with the hydrosphere, or the water systems of Earth. Rain is created when water droplets gather around the particles. This rain, which has been enhanced with minerals from volcanic material, falls to the biosphere and fosters the growth of plants.
The interplay between the geosphere, hydrosphere, and biosphere demonstrates the complex interrelationships between Earth's constituent parts, demonstrating how changes in one sphere can have an effect on others, eventually influencing the environment and sustaining life.

Which phrase best defines the orbit of Earth? A. the position in pace of Earth at a certain time B. the distance from the sun to Earth at any point C. the spin of Earth on its axis as it moves forward D. the path Earth travels as it revolves around the sun
The phrase that best defines the orbit of Earth is the path Earth travels as it revolves around the sun. That is option D.
Rotation of the EarthThe earth is one of the nine planets that makes up the solar system.
An orbit is a regular, repeating path that an object takes around another one.
The earth and other planets travels round the sun. That is to say, the orbit of earth is defined as the path the earth passes through or travels as it revolves around the sun.
The earth rotates about its own axis within 24 hours causing day and night while it travels round the sun in every 365.25 days.
Therefore, the orbit of Earth is the path Earth travels as it revolves around the sun.

3. Would a cliff in the desert or a cliff along the seashore experience more weathering? Explain your answer.
Answer:
A sea shore would have more weathering, because the gust of wind from the shore line will surley weather out the mountain, including the waves washing out rocks.
Explanation:
Pls give brainliest
A seashore would experience more weathering than the desert. This is because of the gust of wind on the cliff of the mountain.
What is Weathering?
Weathering can be considered as the breaking down or dissolving of rocks and minerals on the Earth's surface. Once a rock or mineral has been broken down by the process called erosion, it transports the small bits of rocks and minerals away from each other. Water, acids, salt, plants, animals, and change in temperature are all the agents of weathering and erosion.
A cliff along the seashore would experience more weathering, because of the gust of wind from the shore line. This will surely weather out the mountains, including the waves washing out the rocks and minerals.

Choose the correct order for the formation of a recombinant organism and the expresssion of the
desired product.
I’m stuck on this one any advice?
The order for rDNA is to identify a target gene, select a plasmid, use a restriction enzyme, gene insertion, use ligase, introduce the recombinant DNA and detect recombinant cells. rDNA involves genetic recombination.
Recombinant DNA (rDNA) technologies are used in molecular biology laboratories to create chimeric DNA molecules containing nucleotide sequences from different species.
Recombinant DNA techniques can be used to identify and sequence genes, as well as to discover gene function.
The sequential steps of rDNA technologies are as follow:
Identify a gene of interest.Select a DNA plasmid to be used.Use restriction enzymes to cleave the plasmid DNA.Introduce the gene of interest in the plasmid.Use ligase enzymes to join both nucleotide sequences.Introduce the recombinant DNA molecule into the host cell.Detect and replicate the cells containing the desired recombinant DNA molecule.Learn more in:
