Explanation:
Dominant traits tend to be seen more frequently in a population because there are more dominant alleles. If it seems like in a community that the dominant traits show up more then this means that the dominant alleles are more.
Number of cells in the plant kingdom ?
Explanation:
Hey, there !!
Your question is though because plants are both multicellular and unicellular.
So, let me give you a little idea from whatever i have known.
Inside plant kingdom, there are three divisions,
Thallophyta = composed of mostly unicellular cells.Bryophyta = composed of multicellular cells.Pteridophyta = composed of multicellular cells.These are the information. but if its about type of cells, there are various type of cells such as xylem cells,phloem cells, parenchyma cells, collenchyma cells etc.

You want to determine if a new diet medication will help rats to lose weight. What is the dependent variable? * the rats weight loss diet medication the food
Answer:
the rats weight loss
Explanation:
The dependent variable would the weight of the rats.
The dependent variable is the variable whose value is dependent on another variable during an experiment. It is the actual variable set out to be measured or tested by researchers. The effect of the manipulation of the independent variable is measured on the dependent variable.
Hence, in an experiment aimed at determining whether a new diet medication will help rats to lose weight, the weight loss by the rats would be the dependent variable.

A scientist is testing how caffeine affects people’s sleep. She asks one group of people to drink one can of Coke before bed. She asks a second group of people to drink one cup of water before bed. Over a period of one month, she determines that the Coca Cola drinkers slept 45 minutes less per night than the water drinkers. What is the INDEPENDENT VARIABLE?
Answer:
The type of drink with different caffeine contents.
Explanation:
When conducting an experiment, two variables are looked out for, they are: independent variable and dependent variable. Independent variable refers to the variable being controlled or altered in the experiment in order to induce an effect in the dependent variable, which is the variable being measured. The outcome of the dependent variable is dependent on the input or independent variable.
In this question, the scientist is testing how caffeine affects people's sleep. She uses different drinks i.e. Coca-Cola and water with different caffeine contents to test out it's effect on the time of sleep people in the different groups will have. Therefore, the type of drink is the INDEPENDENT variable because it is being changed to test an effect on the dependent variable. The amount of time of sleep is what is being measured, hence it is the dependent variable.

Which applied force will cause a glass of water sitting on a countertop to move?
A. a balanced force
B. a frictional force
C. a gravitational force
D. An unbalanced force
Answer:
The correct answer is D. an unbalanced force.
Explanation:
If an unbalanced force were applied to the glass of water (for example, someone pushing the glass, lifting it up, etc.), this would cause it to move. However, a balanced force (if two people were to simultaneously pull the glass in opposite directions with the same amount of force) would not cause the glass to move. Gravitational force acts on all objects; the force due to gravity is already acting on the cup at rest and will not cause it to undergo motion. Friction is also already acting on the cup in the form of static friction, making it harder for someone to move the cup, so frictional force will not cause the cup to move either. Therefore, the correct answer is D. an unbalanced force.

How might you model the relationship between a tomato plant and the hornworm caterpillar?
Answer:
This model can be called a parasitic relationship
Explanation:
A parasitic relationship is a form of relationship/interaction between two organisms in which one organism (called parasite) lives at the expense of the other organism (called host); causing harm or death to the host.
A hornworm caterpillar feeds on the upper part of tomato plant leaves, causing harm to the plant in the process. Hence, the tomato plant is the host while the hornworm caterpillar is the parasite.

Carnivores competing for resources may defend their territory. If a species cannot compete very well it could become extinct or move out of the territory. Another thing that could happen is that the competing species could consume all the resources and it could affect the whole food web and ecosystem. It could affect the other species in the ecosystem.
a. True
b. False
Answer:
The correct answer is option A.
Explanation:
All living things need to compete to survive so that they can pass their genes onto the next generation, so yes the carnivores do defend their territory if there is a threat or a lack of resources.
It could also impact other species and the ecosystem since each one is connected. If the competing species consume all the resources then that species is in danger of extinction which in turn affects another species that feed on the first species.
So the answer is true.

Comparing amino acid sequences in proteins has been used to determine the relatedness of organisms. Below is a graphic that shows the amino acid sequence differences between different organisms for a protein keratin. Changes in amino acid sequences are known to cause changes in structure of proteins. Species A Species B Species C Species D Species E Species A 4 11 19 1 Species B 12 18 5 Species C 8 10 Species D 20 Species E Part A. Consider species A, D, and E. Using the data provided, describe how the structures of their keratin proteins would compare. Part B. Keratin is made up of about 450 amino acids. Determine the similarity in percentages between species A and B, A and C, and B and C. Explain how amino acid sequences can be used in determining how closely related two species are. Part C. Based on this data, predict which two species would be more closely related to one another. Part D. Justify your predictions to part C.
Answer:
A) Species A and E are more closely related than either species are related to species D.
B) Between A and B = 99.1%
Between species A and C =97.5%
Between species B and C = 97.3%
Similarity in amino acids sequence reflects similarity in DNA sequence
C) Species A and E are most closely related
D) Species A and E have the most similarity in amino acid sequence, and hence DNA sequence.
Explanation:
A) The amino acid sequences of the protein, keratin, in species A and D has a difference of about 19 whereas species A and E have a difference of only 1. Therefore, it means that keratin in species A and D will have differences in structure whereas between species A and E, they would have almost the same structure.
Also, species D and E have a difference of 20 in their amino acids sequence, therefore, the structure of keratin in both species will have differences in structure.
B) Similarity between A and B:
450 - 4 = 446
In percentage: 446/450 × 100% = 99.1%
Similarity between A and C:
450 - 11 = 439
In percentage: 439/450 × 100% = 97.5%
Similarity between B and C:
450 -12 = 438
In percentage: 438/450 × 100% = 97.3%
The sequence of DNA of species determines their amino acid sequences because information in DNA is transcribed to RNA which are then used to make proteins. Therefore, if a species are very closely related, they are expected to have very similar genetic sequences and thus proteins too. This is reflected in similarity between amino acid sequences in their proteins.
C). Species A and E are most closely related.
D) Species A and E have only a single difference in their amino acids sequence for Keratin. This translates to about 99.7% similarity which is the highest among all the species compared. Therefore, species A and E are most closely related.
how does carbon dioxide in the atmosphere affect oceans and marine life?
Answer:
It interacts the detirment of marine ecosystems.

What are the differences among the five biogeochemical cycle,particularly on the roles organisms play in them?
Answer:The most important biogeochemical cycles are the carbon cycle, nitrogen cycle, oxygen cycle, phosphorus cycle, and the water cycle. The biogeochemical cycles always have a state of equilibrium
Explanation:
Contrary to energy flow, matter, the building block of which organisms are made, flows through an ecosystem in several cycles, from one organism to the next and from living things to the abiotic environment and back.
What are biogeochemical cycles?
The flow of nutrients and other elements between biotic and abiotic forces is referred to as "biogeochemical cycles." The words "bio" and "geo," which refer to the biosphere, "geo" and "chemical," which refer to the elements that flow through a cycle, are the roots of the phrase "biogeochemical."
Atoms make up the preserved stuff that exists on Earth. Since matter cannot be generated or destroyed, it is recycled in a variety of ways throughout the earth's system. The remainder of the elements are present in a closed system, and the earth receives energy from the sun that is reflected back as heat. Major components include:
CarbonHydrogenNitrogenOxygenPhosphorusSulfurThe biotic and abiotic parts of the ecosystem recycle these substances. The abiotic elements of the ecosystem are the lithosphere, hydrosphere, and atmosphere.
Therefore, contrary to energy flow, matter—the building block of all living things—moves through an ecosystem in a variety of cycles, from one creature to the next and from the abiotic environment to the living ones and back again.

Which structures are highlighted? Which structures are highlighted? duodenal glands Peyer's patches (aggregated lymphoid nodules) submucosa gastric glands
Answer: (Note: You will find the image with the highlighted structure in the attached file)
Peyer's patches (aggregated lymphoid nodules)
Explanation:
Peyer's patches are anatomical regions located under the mucosa of the gastrointestinal tract, specifically in the lamina propria of the thin intestine. These patches are nodules or cumulus of lymphatic tissue and other accessory cells, and this is why they represent a huge part of the mucosa´s immunity system.
Peyer's patches belong to the group of lymphoid tissue associated with the intestine, composed of lymphoid follicles distributed along the gastrointestinal tract.
A lymphoid follicle is a cumulus or aggregate of lymphoid cells that do not have a well-defined structure nor organization. In general, these follicles are isolated from each other in the intestine. But in the terminal ileum (The last portion of the thin intestine) they get so close that they might form a plaque. The Peyer´s patches are formed principally by lymphocytes B that synthesize immunoglobulin A, which has an important role in immunity.
