In this project, you will make a graphic to help you understand who the producers and consumers are. You can make your graphic in any way that makes sense to you; a bulleted list, a pyramid, a Venn diagram, etc. Your graphic should be clear and easy to understand. You can create it in a Word document, Power Point Presentation, Publisher, or any other graphics program that you are familiar with. Do additional research if you need to find out about any words on the list.
Click here to make a printout of a pyramid.
From the following list, Separate out the producers. Make sure you have clearly labeled this group.
acorns
deer
mice
apple
trees
eagles
owls
cabbage
frogs
potatoes
carrots
grains
rabbits
chickens
grass
squirrels
corn
horses
wolves
cows
lettuce
worms
Next, separate out the plant eating consumers. These are the ones that eat only producers. Make sure to label this group clearly. Last, separate out the predators, making sure to label this group clearly in your presentation. After completing the lab, respond to the following questions:
Were there more producers than consumers and more consumers than predators on your pyramid? Why or why not? Were there any that could have fit in more than one category?
A mouse eats 100 times his own weight in grain in a lifetime. You can see that plants must produce a great amount of food for just one mouse. What do you think would happen if grain was no longer available for the mouse to eat? How would it affect other organisms in your ecosystem?
Answers
Answer:
Producers:
Acorns (produced by oak trees)Apples (produced by apple trees)Cabbage (a leafy green vegetable cultivated as an annual plant)Potatoes (tubers produced by the potato plant)Carrots (root vegetables, usually orange in color)Grains (wheat (produced by wheat plants), barley (produced by barley plant), etc.)Grass (produces seeds and is a primary food source for many herbivores)Corn (a cereal plant that yields large grains, or kernels, set in rows on a cob)Lettuce (a leafy green plant grown for its often-crunchy leaves)Trees (producing oxygen as a byproduct of photosynthesis and also yielding food items like fruit and nuts)Plant-eating Consumers (Herbivores):
Deer (eat various plants and fruits, they are herbivores)Rabbits (eat grass, roots, and leafy greens; they are herbivores)Horses (eat grass and grains; they are herbivores)Cows (eat grass and grains; they are herbivores)Squirrels (primarily eat acorns, grains, seeds, and fruits)Mice (eats mainly plants, seeds, grains, fruits, and vegetables)Chickens (often fed grains, vegetables, and fruits)Predators (Carnivores):
Eagles (predatory birds that feed on smaller animals; they are carnivores)Owls (nocturnal birds that prey on small mammals, birds, and insects; they are carnivores)Wolves (carnivorous mammals that prey on deer, rabbits, and other smaller animals; they are carnivores)Frogs (amphibians with a carnivorous diet, eating insects, small mammals, small fish, spiders, and worms)Detritivores (although not mentioned in the question, they are crucial in every ecosystem):
Worms (in general, worms are classified as detritivores).To answer your questions:
In this bulleted list, there are more producers than consumers and more consumers than predators. This is typical of most ecological pyramids because each level depends on the one below it for food. There are always fewer organisms at the top of the pyramid because energy is lost at each level due to the laws of thermodynamics.For example, squirrels can be considered both plant-eating consumers (as they eat acorns, tree bark, and fruits) and potential predators (as they can be omnivorous, eating small insects and bird eggs). Similarly, mice can be categorized as plant-eating consumers, but they can also be omnivorous, consuming insects and occasionally the remains of deceased animals.If grain was no longer available, the mouse population would be significantly affected. Mice rely heavily on grains for their energy and nutrition. If this food source were suddenly unavailable, the mice would either need to find another food source, like fruits or vegetables, or their population would likely decrease due to starvation. This change would also impact other levels of the ecosystem. Predators who rely on mice as a food source, like owls and snakes, would find fewer prey available, which could lead to a decrease in their populations as well. Conversely, without mice consuming as much grain, the grain population might increase. However, other herbivores who also eat grains might proliferate, taking advantage of the increased food source and maintaining a balance. This hypothetical situation demonstrates the delicate balance of ecosystems and the potential cascading effects that can occur from changes at any level of the food web.name three important factors that can effect the rate of photosynthesis

A group of researchers transformed E. coli to express
dsRNA that matched a transcription factor, eaf-1. They
then fed these E. coli to C. elegans worms. When the
researchers examined the C. elegans, they found that
they had fewer offspring and were smaller individuals,
with similar characteristics to C. elegans in which eaf-1
had been knocked out.
The students suggested several hypotheses based on
these observations about how RNAi worked:
1. The dsRNA inhibited gene transcription.
2. The dsRNA inhibited mRNA processing.
3. The dsRNA inhibited translation of mRNA into protein.
4. The dsRNA inhibited protein folding.
Mark this and return
The researchers then performed a series of experiments
to determine which hypothesis was correct. The C.
elegans were found to be transcribing eaf-1 into mRNA,
but not producing eaf-1 protein. When the students
directly injected C. elegans with dsRNA and tracked
tagged mRNA, they found the mature mRNA was
degraded in the cytoplasm, and ribosomes were not
binding to it. Which hypothesis is supported by these
observations?
Answers
The hypothesis that is supported by these observations is that the dsRNA inhibited the translation of mRNA into protein (third option).
What does the experiment reveal about dsRNA?In this experiment, the C. elegans worms were transcribing eaf-1 into mRNA but not producing the eaf-1 protein. This phenomenon shows that dsRNA inhibited the translation of mRNA into protein related to the action of E. coli on the worms.
This also explains why the worms affected by this bacteria had fewer offspring and the offspring were smaller.

50% Dd
25% dd
or
1 DD: 2 Dd: 1 dd
Phenotype frequencies75% Dark brown, 25% light brown
or 3 dark brown: 1 light brown
Explanation:
Two heterozygous parents have the genotypes Dd. Therefore, the cross is Dd x Dd.
D d
D DD Dd
d Dd dd
25% (1:4) of the organisms have the genotype DD, and therefore the phenotype is dark brown, since it has two copies of the dark brown fur allele (DD)
50% (1:2) of the organisms have the genotype Dd, and therefore, the phenotype is dark brown since dark brown fur (D) is dominant to light brown fur (d).
25% (1:4) of the organisms have the genotype dd, and therefore the phenotype is light brown, since it has two copies of the light brown fur allele (DD)
"Since proteins are what we are made of and what determine our traits, how might these errors affect resulting traits?"
Answers
Answer:
* The attributes of a living thing rely upon the unpredictable combination of interfacing segments inside it. Proteins do a significant part of the synthetic work inside cells, so they to a great extent figure out what those characteristics are. Yet, those proteins owe their reality to the DNA (deoxyribonucleic corrosive), so that is the place where we should search for the appropriate response.
* The most straightforward approach to see how DNA is coordinated is to begin with its fundamental structure blocks. DNA comprises of four unique sugars that interface with one another specifically. These four sugars are called nucleotide bases and have the names adenine (A), thymine (T), cytosine (C) and guanine (G). Consider these four bases letters in a letters in order, the letter set of life!
* In the event that we connect these nucleotides into a grouping for instance, GATCATCCG we currently have a little bit of DNA, or a short word. An any longer bit of DNA can in this way be what could be compared to various words associated with make a sentence, or quality, that depicts how to fabricate a protein. A still longer bit of DNA could contain data about when that protein should be made. All the DNA in a cell gives us enough words and sentences to fill in as an expert portrayal or outline for a human (or a creature, a plant, or a microorganism).
Explanation:
Obviously, the details are somewhat more confounded than that! By and by, dynamic stretches of DNA should be replicated as a comparative message particle called RNA. The words in the RNA at that point should be "read" to deliver the proteins, which are themselves stretches of words comprised of an alternate letter set, the amino corrosive letter set. Nobel laureates Linus Pauling, who perceived the structure of proteins, and James Watson and Francis Cramp, who later decoded the helical structure of DNA, assisted us with getting this "Central Dogma" of heredity that the DNA code transforms into a RNA message that can coordinate 20 amino acids into an unpredictable protein: DNA - > RNA - > Protein.

What are ribosomes?
The biological machinery that produces proteins is called a ribosome. Each cell has several ribosomes, which are each composed of two subunits. These two subunits form a tight seal around the messenger RNA molecule before moving down its length and reading each three-letter codon.
The transfer RNA, whose base sequence matches that of the messenger RNA, docks to the ribosome. A specific amino acid can be added to the end of the expanding protein chain by pairing each three-letter messenger RNA codon with the corresponding anticodon on a particular transfer RNA. Once the protein is finished, the ribosome fragments.
The process of making proteins in a cell takes place at an intercellular structure called a ribosome, which is formed of both RNA and protein. The messenger RNA (mRNA) sequence is read by the ribosome, which then converts the genetic code into a specific string of amino acids that develop into extended chains and fold to create proteins.
Therefore the correct option is B.

(a) If a particular gene is located on the Z chromosome of this lizard species, describe why a lizard with a ZW genotype has a greater probability of expressing the recessive phenotype for the trait than a lizard with the ZZ genotype does.
If there is no dominant allele for a trait present on a homologous chromosome to mask the recessive allele, the recessive phenotype will be expressed. In this case, the gene is located on the Z chromosome. In an individual with a ZW genotype (female) there is no homologous Z partner, meaning whatever allele is present on the solitary Z chromosome will be expressed.
Answers
A lizard with a ZW genotype, on the other hand, has a greater chance of expressing the recessive phenotype than a lizard with a ZZ genotype.
There is no corresponding W chromosome in a man with a ZZ genotype to mask the expression of any dominant or recessive alleles present on the Z chromosome.
This is due to the fact that a ZW genome has only one copy of the Z chromosome, whereas a ZZ genotype has two copies of the Z chromosome.
If the trait's recessive allele is present on the Z chromosome, an individual with a ZW genotype is more likely to exhibit the recessive phenotype because there is no dominant allele present on the W chromosome to mask the expression of the recessive allele on the Z chromosome.

When all available water has been used up in a soil, what is left ?
1. Is unavailable to plants.
2. Can only be obtained by large plants.
3. Is too small to make any effect.
4. Will only be used by certain plants.
Answers
Answer:
When all available water has been used up in a soil, the remaining water is typically unavailable to plants. Therefore, option 1 is the correct answer.
Plants can only absorb water that is in the soil's pore spaces and is not too tightly bound to soil particles. Once all the available water has been used up, the remaining water is held too tightly to soil particles for plants to access it. This can lead to water stress and drought conditions for plants, and can also negatively affect soil fertility and other aspects of ecosystem health.
