Some people's earlobes dangle or flap unattached, while others don't. This trait is genetically determined. Use the genetics simulation to explore the genes that determine whether earlobes are attached or unattached. One trait is dominant and the other is recessive. See what happens when you cross parents with different genetic combinations. Follow the specific instructions for each trial.

If u looked at a SA cells and cardiac muscle cells under a microscope, do u think they would look the same or different from each other? Explain ur reasoning HELP MEE PLSSSSS
Answers
Answer:
They look a little bit different. SA cells contain fewer mitochondria, fewer myofibers, and a smaller sarcoplasmic reticulum. This means that the SA node cells are less equipped to contract compared to the atrial and ventricular cells.

what are the the four main categories of organic macromolecules ?
Answers
Answer:
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions.
Four main categories of organic macromolecules are as follow:
carbohydratelipidsproteinsnucleic acidWhat are macromolecules?Macromolecules are polymers containing long chains of molecular sub-units known as monomers. These play an important role in biophysical processes and composed of thousands of atoms that are covalently bonded.
Carbohydrate is a biomolecule having carbon, hydrogen and oxygen atom.It is the main source of energy of the body.
Lipids are macromolecules that are insoluble in water and the main function is to serve as structural component of cell membrane.
Proteins are macromolecules that are extremely complex in structure and made up of amino acid residues joined by peptide bonds.
Nucleic acids are biopolymer macromolecules and composed of nucleotide. The function is to carry genetic information which helps to make RNA.

What regulates breathing rate and how does the body sense when to breath?
Answers
Answer:
Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).
Explanation:
The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).
The stage in the mentrual cycle usually lasting from 3to five days when fertilization does not occur.

The average molecular weight of proteins encoded in the human genome is about 50,000. A few proteins are very much larger than this average. For example, the protein called titin, which is made by muscle cells, has a molecular weight of 3,000,000. Estimate how long it will take a muscle cell to translate an mRNA coding for an average protein and one coding for titin. The average molecular mass of amino acids is about 110 daltons. Assume that the translation rate is two amino acids per second.
Answers
Answer:
13,636 seconds = 227.3 minutes = 3.79 hours
Explanation:
The titin protein has a molecular weight of 3,000,000 daltons, while the average molecular mass of one amino acid is 110 daltons, so it is expected that this protein is composed of 27,273 amino acids (3,000,000 daltons/110 daltons = 27,272.72). Moreover, and since the translation rate is two amino acids per sec, it is expected that the protein will be synthesized in approximately 3.79 hours (27,272.72/2 = 13,636 seconds = 227.3 minutes = 3.79 hours).

state two features of diffusion that do no apply to active transport
Answers
What does active transport require that diffusion does not? Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
What two features distinguish active transport from diffusion? An example of diffusion is oxygen moving from the airways to the lungs - there is very little oxygen in the lungs but lots in the air. Active transport is the movement of particles from an area of low concentration to an area of high concentration. This process requires energy (ATP)
What are the 2 key features of active transport? There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient. An example of active transport in human physiology is the uptake of glucose in the intestines.

How does cooling of magma affect crystal size?
A) Slow cooling creates small crystals
B) Fast cooling creates both large and small crystals.
C) Slow cooling creates large crystals
D) Fast cooling create large crystals
Answers
Answer:
When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.
Answer:
I learned about this, Uhm...
C is the right answer bc igneous rocks cool and form crystals.
Lava, since it comes out of a volcano, cools faster and has smaller crystals since they could not be developed enough.
Magma, still underground, cools slower than lava because of all the density and heat, which causes bigger crystals.

The modern cell theory doesn't say
A all living things are multicellular
B cells are the smallest living unit in all organisms
C all cells come from other cells
D all living things are made of cells
Answers
Answer:
A
Explanation:
Modern cell theory states: cells are the basic unit of structure and function for all living things, all cells come from preexisting cells, and all living things are made from cells. It does not state that all living things are multicellular, in fact there are plenty of unicellular organisms. Therefore the answer is A.
