Trout X


Image depicts a cladogram with hagfish, trout, salamander, lizard, bird, rabbit, and tiger represented. Trout diverge from hagfish with the introduction of jaws. Salamander diverges from trout with the introduction of lungs. Lizard diverges from salamander with the introduction of claws and nails. Bird diverges from lizard with the introduction of feathers. Rabbit and tiger diverge from lizard with the introduction of mammary glands.
They are more closely related to tigers than they are to birds.
They became able to produce mammary glands as a result of lacking feathers.
They evolved into a separate species due to the presence of mammary glands.
They share a more recent common evolutionary ancestor with salamanders than they do with lizards.

Answers

Answer 1

Answer:

A. They are more closely related to tigers than they are to birds.

Explanation:

Short answer: I took the test

Actual explanation:

-If you look at the first graphic that you have, you will notice that rabbits and tigers have all the same boxes checked off. AND birds and rabbits only have 3 checked off.

-salamanders actually have less in common with rabbits than they do with lizards, salamanders have 3 things in common, and lizards only have 2, proving option D. wrong. (if you are wondering where I got that evidence, look at the chart) AND if you look at the cladogram, lizards are closer to the rabbits than salamanders meaning that lizards have a more common ancestor (I think?) But nevertheless, it it still wrong, because of the above evidence.

- The options with mammary glands are also incorrect for these reasons, B. makes no sense, literally no sense, why would not be able to produce mammary glands with feathers, so B, is automatically out. With option C, rabbits did not evolve into a whole new species, it is the clade showing that tigers and rabbits both have mammary glands. There is no showing of a new species on the cladogram, and I don't think that it makes sense to evolve into a whole species just because of mammary glands.

- Now, if you look at the cladogram again, you wills see that tigers and rabbits are closest together, meaning that they are closely related. BUT, birds and rabbits are also the closet together, so, refer back to point a, that the chart shows that birds only share 3 out of the 4 that rabbits and tigers share. so that's that.

So after doing the work, option A. Rabbits are more closely related to tigers than they are birds. (and If you read my long explanation THANK YOU I put time and effort into it to make it accurate :))

Hope this helped :))                                                                                                    ~addison

most of the energy that your brain uses comes from

Answers

Answer:

Glucose

Explanation:

The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.

Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.  

Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.  

The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.

Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.

A student made a list of structures are observed in cells from two different organisms which statement describes the most likely difference in the way that organism one and organism two obtain energy

Answers

You didn't include options or statements, however I'll assume these list of structures observed in cells are in eukaryotic cells. Specifically an animal and plant cell. An animal obtains energy from eating food, using the mitochondria to convert that energy into ATP which is more convenient for the cell to use. A plant obtains energy by getting energy from the sunlight. The chlorophyll is in charge of this and uses photosynthesis in order to make this sunlight into the chemical energy found in food. That is when the plant cell uses the mitochondria to convert that chemical energy into ATP for the cell to use.

Explanation:

The graph above shows the initial rate of an enzyme-catalyzed reaction at
different substrate concentrations in the presence of a constant
concentration of the enzyme.

Connect the primary structure of the enzyme to its overall shape.

Answers

The overall shape of an enzyme changes after the attachment with the substrate.

Enzymes are proteins composed of amino acids that linked together in one or more polypeptide chains. This sequence of amino acids in the form of  polypeptide chain is known as the primary structure of an enzyme.

The tertiary structure is the enzyme's overall three dimensional structure, which occurs due to interactions between the R groups of the amino acids that make up the protein and the active sites of the substrate with which the enzyme can attach so we can conclude that the overall shape of an enzyme changes after the attachment with the substrate.

The primary structure of enzymes determinies their functions and their secondary and tertiary structures. R groups remain in the center of the molecule and stabilize the structure.

--------------------------

To answer this question, we need to remember that enzymes are proteins, and hence, they share many properties. From now on, we will refer to the enzyme as proteins or molecules.

AMINO ACIDS

Amino acids are organic molecules. They are composed of a central carbon, one hydrogen atom, one carboxyl group (COOH), one amine group (NH2), and one R group.

The composition of the R group is what makes them different from each other.

PROTEINS -enzymes-

Proteins are amino acid polymers linearly arranged and connected by peptidic bonds. These molecules characterize by their different structures.

The peptidic bond is the union of two amino acids by their carboxyl and amine groups.

The R group of each amino acid is involved in stabilizing the molecule through their interactions.

The amount of amino acids that compose the polypeptide and their order in the chain determines the primary structure of the protein. The primary structure of the proteins determines the tertiary one.

Protein functions also depend on the aminoacids sequences. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.

 

PROTEIN STRUCTURE

The primary structure refers to the sequence in which the amino acids are arranged in the chain.

The secondary structure is the folding that the polypeptide chain adopts thanks to the formation of hydrogen bonds.

The three-dimensional structure makes them even more stable in the environment and capable of properly accomplishing their biological role.  

When proteins are composed of more than one polypeptide subunit, they arrange in a fourth structure, named quaternary structure.

The hydrophilic R-groups remain in the center of the molecule, facing the protein interior, and avoiding interaction with water.

If the first nucleotide after the promoter on the bottom DNA strand is changed from C to T, what would the resulting nucleotide be on the mRNA

Answers

I’m pretty sure it’s G U

When the DNA's C is changed to T, the corresponding nucleotide on the mRNA strand will be A (adenine) to maintain the complementary base pairing.

Nucleotides encode genetic information in DNA. Due to complementary base pairing laws, DNA sequence alterations impact mRNA transcript nucleotides. If the first nucleotide following the promoter on the bottom DNA strand changes from C (cytosine) to T (thymine), the matching mRNA strand nucleotide becomes A.

Because C pairs with G (guanine) in DNA and RNA. T in DNA matches A in RNA owing to complementary pairing. The DNA sequence will influence the mRNA sequence during transcription, which may impact the protein synthesised during translation.

while a neuron membrane is depolarizing its __________.

Answers

Given what we know about the depolarization of neurons, we can confirm that while a neuron membrane is depolarizing its sodium gates are fully open.

Throughout the human body, sodium is often used to cause shifts in membrane potentials, as well as a variety of other metabolic processes, due to the electric charge of this ion. One such example is the neuron, which uses a flood of sodium ions to depolarize its membrane.

During depolarization, the membrane potential changes from a negative charge to that of a positive one. This is caused by the rapid flooding of sodium into the cell, which increases the positive charge in the interior of the cell and thus affects the membrane's potential.

What is the major consideration in setting the lower limit of cell size?
A. The cell size must be small as to fit all the processes and structures to support life.
B. The cell must be large enough to fight the pathogens.
C. The cell must be large enough to attach to a substrate.
D. The lower limit should be small enough for the cell to move in the fluid efficiently.

Answers

Answer:

c

Explanation:

The lower limit should be small enough for the cell to move in the fluid efficiently. Therefore, option (D) is correct.

The major consideration in setting the lower limit of cell size is the need for the cell to move in fluid efficiently. As cells become smaller, their surface area-to-volume ratio increases, allowing for more effective exchange of nutrients, gases, and waste products across their membrane.

This is particularly important for cells living in fluid environments where diffusion plays a crucial role in these exchanges. Small cells have an advantage in absorbing and expelling substances due to their larger surface area relative to their volume. Therefore, the efficiency of nutrient uptake and waste removal becomes more effective with smaller cell sizes, making efficient movement in fluid environments a significant factor in determining the lower limit of cell size. Thus, option (D) is correct.
