Answer:
The word "heterozygous" simply means that your biological mother and your biological father, when they contributed their copies of a particular gene to you, they did so in a way so that the DNA sequence is slightly different. It can be different at one point in the gene, or it can be different at dozens and dozens of different points in the gene. i know it is B because the web showed me something that told me b but it would not let me submit that
so it is B

if you measure the age of a fossil using 14c dating and determined its age to be about 17000 years old, how much of the rock should be made of 14N
Answer:
Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that. Carbon dating is used by archeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50,000 years. Carbon is found in different forms in the environment – mainly in the stable form of carbon-12 and the unstable form of carbon-14. Over time, carbon-14 decays radioactively and turns into nitrogen. A living organism takes in both carbon-12 and carbon-14 from the environment in the same relative proportion that they existed naturally. Once the organism dies, it stops replenishing its carbon supply, and the total carbon-14 content in the organism slowly disappears. Scientists can determine how long ago an organism died by measuring how much carbon-14 is left relative to the carbon-12.
The percentage of 14C is close to 12%
Carbon-14 is a radioactive isotope chemical element characterized by containing 6 protons and 8 neutrons. Its main function is the dating of organic specimens because it is present in all organic materials.
This is because once an organism dies carbon-14 slowly decreases over year as the lifespam of carbon dioxide is between 5000 and 30000 years. The way it decreases is determined by a mathematical function, but to make it easier there are graphs like the one below that show the process.
According to the graph showing the amount of carbon in an organic material when a fossil is 17,000 years old, the percentage of Carbon - 14 is about 12%.

. What causes a hurricane to form
will give brainliest to smartest answer
Answer:
For one to form, there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.
Explanation:
In short pressure zones over warm ocean
Answer:
When warm moist air over the water rises, it is replaced by cooler air.
The cooler air will then warm and start to rise.
If there is enough warm water, the cycle will continue and the storm clouds and wind speeds will grow causing a hurricane to form.

Explanation:
---> The process of selecting a few organisms with desired traits to serve as parents of the next generation. Selective breeding of plants and animals to promote the occurrence of desirable traits in offpsring.?
The process of determining a few creatures possessing desirable characteristics to participate as the founders of the coming generation is Artificial selection.
Artificial selection
The discovery of advantageous characteristics among living things by humankind, as well as the efforts performed to improve and maintain such traits throughout upcoming populations or years.
It follows the same procedure as evolutionary processes, with the exception that with biological evolution, nature determines the decisions rather than humans.
Thus the above response is correct.

Select the most complete model that shows the cellular structures present in all living cells.
Answer animal cells
Explanation:
The most complete model that shows the cellular structures present in all living cells is option B. So, the correct option is (B).
What is Animal Cell?An animal cell is defined as the type of eukaryotic cell that lacks a cell wall and has a true, membrane-bound nucleus as with other unicellular organisms.
Animal cells are generally smaller than plant cells. Animal cells are irregular in shape due to the absence of a cell wall. But animal cells share other cellular organelles with plant cells as both evolved from eukaryotic cells.
Animal cells consist of following cell organelles:
Cell membraneNucleusNuclear membraneCentrosomeLysosomeCytoplasmGolgi ApparatusMitochondriaRibosomeEndoplasmic reticulumVacuoleNucleoporeThus, the most complete model that shows the cellular structures present in all living cells is option B. So, the correct option is (B).

Answer:
sorry i cant understand clearly
Explanation:
i hope its help more
Answer: The equipment will "push back" on the astronaut with the same amount of force.
Explanation: Newton's third law of motion can be summed up as "For every action, there is an equal and opposite reaction." This means that when the astronaut applies force to push the object, that object will apply an equal amount of force to the astronaut.
