Biology IA ideas
Hi, I’m struggling to choose a biology IA topic can anyone help me. I was looking for something to do with ecology or evolution
Answers
Answer:
Evolution, of course is the process of change in all forms of life over generations and evolutionary biology is the study of how evolution occurs. Biological populations evolve through the changes in the organisms' observable traits. All life on the planet exists because it evolves to best fit the environmental conditions and those who adapt best, pass on those characteristics to their offspring. In other words, descent with modification.

How did researchers try to change the avian flu virus to make it more easily spread between humans?
Answers
Answer:
They did not try to do this.
Bird flu, when it first crossed over to humans, was not human to human transmissible.
But as a virus evolves, we expect sooner or later that it would get that ability.
Researchers do not need to try to get evolution what evolution would do all by itself anyway.
I know that very often the people that say that the Chinese created a virus in a lab are also people that say that they do not believe in evolution.
Stop being a hypocrite about it.
No one was researching how to do this, no one needed to research how to do this because this is done naturally by natural evolution, and no one would want to do this for any reason.
When you accuse “researchers” of trying to do something that has no benefit to science then you accuse all science researchers when you lie about it.

The classification system for organisms has changed from seven levels to eight. This happened because
scientific consensus changed as scientists learned more about organisms.
scientists did not test the seven-level system often enough to lead to consensus.
the eight-level system of classification is an emerging idea that needs more testing.
the seven-level system of classification was not supported by scientists.

Answer:
scientific consensus changed as scientists learned more about organisms.
Explanation:
The classification system for organisms has changed from seven levels to eight level of classification system because scientists learned more about organisms. This new learned information allow scientists to change the existing classification system. When the scientist find new species that may have to change classification systems in order to accommodate them and placed them accurately in the classification system.

Explain two ways that food is converted/changed as it passes through
the digestive system.
Answers
Answer:
The stomach stores swallowed food and liquid, mixes the food and liquid with digestive juice it produces, and slowly empties its contents, called chyme, into the small intestine.
Explanation:
plssssss follow meee.....
The two ways through which food is converted/changed as it passes through the digestive system may significantly include digestion and absorption. Protein must be broken down into amino acids. Starches break down into simple sugars. Fats break down into fatty acids and glycerol.
What is the digestive system?The digestive system may be defined as a type of body system that definitely consists of the organs that take in food and liquids and break them down into substances that the body can use for energy, growth, and tissue repair.
As food passes through the Gastrointestinal tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
Two important functions of the digestive system are digestion and absorption. The nutrients that come from food are derived from proteins, fats, carbohydrates, vitamins, and minerals.

all plant bodies(root,stem and leaf) are externally covered by epidermis but why woody plant is covered by barks
Answers
Answer:
Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.
As to why, the bark adds layers to the inside ring of the vascular cambium, the outside is pushed outward. The cells die off, and the fibrous matrix of cellulose and lignin molecules remain. This hard structure forms the bark, and protects the tree or plant from many forms of damage.

Which of the following describes a scenario that would result in the phenotypic change shown in the graph?
(please someone help )
Answers
C is the correct answer
This is an example of stabilizing selection in which there are selective pressure acting against the two extremes of a trait. This results in the intermediate trait to rise in frequency in the population
The graph given below shows the process of stabilizing selection, where the individuals have an intermediate phenotype increase in number. This scenario also refers to heterozygous advantage.
What do you mean by Phenotype?The phenotype may be defined as the appearance or manifestation of a specific character. It is also referred to as a trait.
In stabilizing selection, selection pressure is applied to both the extreme ends, which means the purebred characters possess selection pressure. And due to this the individuals with intermediate phenotypes are more favored.
Therefore, the graph given below shows the process of stabilizing selection.
