Answer:
Sometimes a single gene may affect more than one trait. This is called pleiotropy. An example is the gene that codes for the main protein in collagen, a substance that helps form bones. The gene for this protein also affects the ears and eyes.
Explanation:
different organisms can display similar anatomical traits. for example, cats and dogs both have four limbs. why do these different animals have similar anatomical arrangements?
different organisms can display similar anatomical traits because they share common ancestral origin
Since Darwin's time, the study of comparative anatomy has mostly focused on bodily traits that are homologous, or those that, regardless of their current function, may be found in other species and share the same evolutionary ancestry. Such structures may have totally diverse appearances and serve distinct functions, yet they nonetheless share a common structure with an animal that was their ancestor. For instance, the forelimbs of humans, birds, crocodiles, bats, dolphins, and rodents have all undergone various evolutionary modifications to serve various purposes, but they can all be linked back to the fins of crossopterygian fishes, where that fundamental arrangement of bones initially developed. similar structures ,in this way they share common traits

Sam's Earth Science class is about to walk the planets. What does that mean? Well, his teacher has tied a large helium
balloon outside and students will pace off the distance to each planet, using this scale as a guide. Sam's teacher has
told the class to use the idea of a "pace" as a unit of measure for the activity. A pace is two steps-one with each foot.
One pace is about 1 meter. The students predicted how many paces it would take to reach each planet. It takes 6
paces to reach Mercury and Pluto was 592 paces from the start. When they had completed the activity, one student
had stopped at 287 paces. What planet did that student represent?

How accurate was the prediction about the contents of the story the tell-tale heart?
Poe's "The Tell-Tale Heart" narrator serves as an illustration of an unreliable witness. The narrator's unreliability is based on his attempts to mislead the reader, to go off topic, and to cover up his omission of important details.
A person who thinks they are crazy or insane is said to have a heart with a tall tale to tell/The Tell-Tale Heart. The police were looking into it when he heard his own heartbeat again, which he had mistaken for the elderly man's in the dark in The Tell-Tale Heart.

In the 1950s, the structure of DNA was discovered by using models and x-ray chromatography. Currently, science has used advanced technology to completely map out the genes in a human’s body. What would be the best advantage of using this information?
Answer:
Recently around 2008 i believe a female scientist found the end of our chromosomes and what the enzyme telomerase did.
Explanation:
What was awesome was they telomerase fixes the small fragements of DNA that degrade over time. A study was done on mine one was treated with the enzyme the other was not keep in mind the mice were old.

you and your friend are walking along a beach in Maine on January 15, at 8 am. you notice a thermometer on a nearby building that reads -1 c. you also notice that there is snow on the roof of the building and icicles hanging from the room. you further notice a pool of sea water in the sand near the ocean. your friend looks at the icicles and pool and says, "How come the water on the if frozen and the sea water is not?" you answer, "I think that the salt in the sea water keeps it from freezing at -1c." your friend asks, "How can you be sure?" you answer, "im going to get some fresh water and some salt water and expose them to a temperature of -1c and see what happens."
What is the independent variable?
What is the control group?
Answer:
the independent variable is salt water, the control group is fresh water
Explanation:
you are testing the effect of salt on water freezing or not. freshwater does not have salt, so it will be the control since you know it will freeze. salt water has salt, and since that is what you are testing, your salt water is your independent variable.
do not confuse your independent variable with your dependent variable!

color (r). If a brown Irish Setter is crossed with a heterozygous red Irish Setter, which ofthe following genotypic ratios can
be expected?

2 RR: 1 Rr: Orr
Oь
1 RR: 2 Rr: 1 rr
Ос
2 RR: O Rr: 2 rr
Od
O RR: 2 Rr: 2 rr
Answer:
2 Rr, 2 rr. (2:2 ratio)
Explanation:
The offspring will be Rr Rr and rr rr.
Since the red coated parent is heterozygous the recessive gene will have more of a chance to show when bred with the recessive brown Irish Setter.

What initially causes a nerve impulse? release of enzymes out of the neuron movement of chemicals into the dendrites of the neuron pathogens attacking the dendrites of the neuron red blood cells bathing the neuron
Answer:
movement of chemicals into the dendrites of the neuron
Explanation:
Nerve impulse occurs when electrical gradient is moved across the plasma membrane of a resting neuron this is done when the neuron receives a chemical signal from another cell or some other type of stimulus. This action potential then travels down the neuron’s axon as an electric current.
Resting potential occurs because of the difference in electrical charge across the plasma membrane of a neuron.
An electrical gradient is maintained by the sodium-potassium pump this is done across the plasma membrane of a neuron when it is not transmitting a nerve impulse this is the resting potential of the neuron.

This type of endocytosis is the cellular process of engulfing liquid particles by the cell membrane.
Pinocytosis is a type of endocytosis in which a cell absorbs minute quantities of extracellular fluid (literally, "cell sipping").
The process by which the cell takes in the liquids together with dissolved tiny molecules is known as pinocytosis (the Greek word pino meaning "to drink"). The cell membrane folds during this process, forming tiny pockets that catch the cellular fluid and other dissolved materials.Pinocytosis and phagocytosis are the two primary kinds of endocytosis. Pinocytosis, commonly referred to as "cell drinking," is the process by which minute aqueous particles and the membrane receptors that identify them are taken up by the body.Big endocytic vesicles termed phagosomes are used in the process of phagocytosis, a particular type of endocytosis, to consume large particles like dead cells and bacteria.In order to absorb nutrients from the gastrointestinal tract's lumen, pinocytosis is seen in the small intestine's microvilli. Similar to this, it is seen in the kidney's duct cells while urine is being produced.Learn more about endocytosis here:

A scientist plans to find out the cause of decrease in bird population in a location. He interviews 50 people who work in the local oil mine and 45 of them believe that the mine does not affect the birds. The scientist concludes that 90 percent of people in the location believe that the local oil mine does not cause decrease in bird population. Why is the scientist's conclusion most likely unreliable? the source of information could be biased the investigation is done by only one person bird population cannot be measured accurately the results of the investigation cannot be repeated
Answer:
The scientist is unreliable since it was supposed to be collecting data on why the birds are dying not why people think they are dying. Also the data would be very biased because he is asking people if they think they are contributing to the problem.
Answer:
A: The source of information could be biased

Answer:
Cryopreservation
Plant Vitrification Solution 2 (PVS2) and Plant Vitrification Solution 3 (PVS3)
Explanation:
Cryo-preservation or cryo-conservation is defined as the process of preservation of all cellular and structural elements such as cells, organelles, tissues, organs, or any other biological constructs by cooling to very low temperatures.
Two commonly used solutions in plants for this purpose are Plant Vitrification Solution 2 (PVS2) and Plant Vitrification Solution 3 (PVS3). Plant Vitrification Solution 2 (PVS2) is consists of, w/v, 0.4 M sucrose, 30% glycerol, 15% DMSO and 15% ethylene glycol and Plant Vitrification Solution 3 (PVS3) comprising, w/v, 50% sucrose and 50% glycerol.
