Which of the following best describes the producers in a terrestrial food web?
a- They convert energy from the sun to chemical energy.
b- They are at the top of the energy pyramid.
c- They are unaffected by decomposers.
d- They obtain their energy from consumers.
Answer:
The correct answer is - a- They convert energy from the sun to chemical energy.
Explanation:
Producers in any food web or ecosystem are the organism that can produce the food and energy on their own. Normally these organisms are green plants that can perform photosynthesis in order to produce chemical energy from light energy that comes from the sun.
Producers not only provide food and energy to themselves but also provide food and energy to each trophic level directly or indirectly. Producers are present at the base of the energy pyramid.

You are on a task force to implement Warn-on-Forecast in a town prone to tornadoes. What would you do to lower the risks of using this technology?
Answer:
We can educate the residents on the changes that are occuring to the current forecasting plan. Then we can explain the steps that we can take during an emergency. To make sure residents understand more about the occurances, we should explain it more clearly and thoroughly. Then the residents would be prepared during a crisis.
Explanation:
Hope this helps
^_^
Answer:
The first step would be to educate the residents on the changes to the current forecasting plan. Then explain the steps they should take during an emergency. To make the residents understand more clearly, the task force should work with local media to provide clear directions to residents. Then the residents would know what to do in an emergency.

a. Eric H. Davidson
b. Eric Carroll
c. Isabelle S. Peter
d. Jennifer Doudna
Answer:
a. Eric H. Davidson
Explanation:
Eric H. Davidson was a developmental biologist whose work helped to understand gene regulation networks in an evolutionary context, being a pioneer in understanding embryogenesis at the genome level. He especially studied sea urchin development, a model animal for developmental biology and genomics. He focused on the animal's nucleic acid properties through the process of hybridization (which has enabled us to understand molecular interactions during development as a whole system), shedding light on the molecular basis of sea urchin development. Eric H. Davidson also compiled the first list of 'fully sequenced' sea urchin genes, involving especially transcription factors, and their interactions with cis-regulatory sequences.
Answer:
a. Eric H. Davidson
Explanation:
Davidson, a developmental biologist, was a pioneer researcher and theorist of the gene regulatory networks that perform complex biological processes, such as the transformation of a single-celled egg into a complex organism. His work helped to reveal how the DNA sequences inherited in the genome are used to initiate and drive forward the sequence of steps that result in development.
What impediments do you think a rover might face, whether physical or technological, while exploring and collecting samples on Mars?
Answer:
Degradation of mobility,
Instability and collision (human or machine),
Mechanical failure, and.
Rovers that move too slowly.
The Impediments that a rover would face while exploring and collecting samples on Mars are :
Mechanical failure Collision Reduction/breaking down of mobility Slow movement of RoverRovers are exploration devices that are used to collect samples/information about a terrain ( mostly in space like Mars ) and some of the samples they collect include : dust, sand and rocks.
Some of the technological impediments face by space rovers includes: mechanical failure ( the failure of rover to work efficiently due to wear and tear or other mechanical factors. )
The Rovers can collide with each other or even human due to force of gravity. the degradation of mobility is another physical impediments while the slow movement of the Rover in Mars due to gravitational forces is considered a physical impediment.
Hence we can conclude that some of the physical and technological impediments faced by Rover are : Mechanical failure, Collision, Reduction/breaking down of mobility ,Slow movement of Rover

Infer: Parrotfish rely on corals for protection and shelter. Look at the parrotfish population over time. Why did the parrotfish population increase at first and then later decline?
Answer:
Lack of shelter.
Explanation:
Although I cannot see the graph of the population over time, I am assuming it was exponentially rising and then began to decline. This is because the parrotfish were able to populate only until the species ran out of shelter. Once it ran out of shelter, the exposed fish began to die due to predators or the environment.
It may also be because of the drastic decline of living coral reefs. As coral reefs die, so do livable habitats for the parrotfish. As a result, the parrotfish decrease in population as fewer corals are available for the fish to live in.

Which bHaving the ability to roll or curl the tongue up along both sides to form a tube is a dominant trait. Which diagram represents the chromosomes in a person that does not have this abilitest describes the outcome of DNA replication
Answer:
dna
Explanation:
select the true statement about dehydration synthesis or hydrolysis
1.) during hydrolysis, an enzyme joins two water molecules, producing polymer
2.) during dehydration synthesis a water molecule breaks apart two monomers
3.) during dehydration synthesis and enzyme joins two monomers water is a byproduct
4.) during hydrolysis, a monomer breaks apart into two polymers,water as a byproduct
The true statement is that during dehydration synthesis, an enzyme joins two monomers and water is a byproduct.
WHAT IS DEHYDRATION SYNTHESIS:
Dehydration synthesis is a reaction that involves the joining together of two or more smaller molecules to form a much larger and complex molecule accompanied by the release of water (H20). During dehydration synthesis, the hydrogen (H) of one monomer combines with the hydroxyl group (OH) of another monomer releasing a molecule of water.An example of dehydration synthesis is the reaction of glucose molecules to form larger polysaccharides.

In pea plants, there are two alleles for the gene controlling Flower Color, with the allele for Purple Flowers (P) being completely-dominant to the allele for White Flowers (p). Another gene controls Flower Position with the allele for Axial Flowers (A) being completely-dominant to the allele for Terminal Flowers (a). If a plant that was true-breeding for Purple-Axial Flowers was crossed with a plant that true-breeding for White-Terminal Flowers, what would be the expected phenotypic ratio two generations later

How does the age of a tree relate to its size?
Answer:
Árbol de envejecimiento fórmula La fórmula de envejecimiento del árbol puede estimar la edad de un árbol multiplicando el diámetro del árbol por su factor de crecimiento. Es más exacto con bosque y árboles rurales en lugar de árboles urbanos, que a menudo se cultivan en condiciones menos ideales que pueden atrofiar su crecimient
Answer:
If you know when the tree was planted, you can easily and accurately determine its age. The second most accurate way to estimate tree age is to count the annual rings of wood growth. Annual rings can be counted using two different methods. You can extract an increment core from the tree using an increment borer.
