I made it 15 points someone answer...please.
neuron collection of neurons nervouse system and brain
Final answer:
The order from simplest to most complex is the neuron, collection of neurons, nervous system, and then the brain, with the brain being the most complex as it controls numerous vital functions and processes in the body.
Explanation:
If given the terms brain, nervous system, neuron, and a collection of neurons, the order from SIMPLEST TO MOST COMPLEX is as follows:
NeuronCollection of neuronsNervous systemBrainThe neuron is the basic functional unit of the nervous system, each transmitting electrochemical signals. A collection of neurons forms complex networks that can communicate and process information but are less complex than the entire nervous system. The nervous system, comprising the central and peripheral nervous systems, orchestrates the activity of the entire body, making it more complex than just a group of neurons. Finally, the brain, as the command center of the nervous system, is the most complex due to its vast array of functions including consciousness, voluntary and involuntary movement control, and bodily functions.
Cell membranes are selectively permeable, regulating which substances can pass through, as well as how much of each substance can enter or exit at a given time. In cells, some molecules can move down their concentration gradients by crossing the phospholipid portion of the membrane directly, while others must pass through membrane proteins. Which of these statements does NOT apply to facilitated diffusion?
Facilitated diffusion is a form of passive transport that involves the movement of molecules down their concentration gradient with the help of specific transport proteins.
Explanation:Facilitated diffusion is a form of passive transport that allows large, polar, or charged molecules to cross the cell membrane with the help of specific transport proteins. Unlike simple diffusion, facilitated diffusion does not require energy and involves the movement of molecules down their concentration gradient. It is important to note that facilitated diffusion only refers to the movement of substances through membrane proteins and not the direct crossing of the phospholipid bilayer.

In Betta fish, colored bodies (B) are dominant to white bodies (b), and blue tails (T) are dominant to black tails (t). A Betta fish that is homozygous for having a colored body and a blue tail (BBTT) is crossed with a Betta that is white with a black tail (bbtt). What are the chances of producing an offspring that is white with a blue tail? *
Answer:
0
Explanation:
This question involves two genes in Betta fish; one coding for body color and the other coding for tail colour. The allele for colored body (B) is dominant over the allele for white body (b) in the first gene while allele for blue tail (T) is dominant over allele for black tail (t) in the second gene.
Thus, in a cross between a Betafish that is homozygous dominant for both genes (BBTT) and homozygous recessive for both genes (bbtt), each parent will produce only one type of gamete combination
BBTT- BT
bbtt- bt
Using this in a punnet square, all offsprings will possess a genotype: BbTt.
Since alleles B and T are dominant, a Bettafish with genotype BbTt will be phenotypically color-bodied and blue-tailed.
Hence, according to the question, the probability of producing an offspring with white body and blue tails will be O since no offspring has such genotype.
The chance of producing an offspring that is white with a blue tail from the described cross in Betta fish is 3/16 or about 18.75%.
To determine the chances of producing an offspring that is white with a blue tail when a Betta fish that is homozygous for having a colored body and a blue tail (BBTT) is crossed with a Betta that is white with a black tail (bbtt), a Punnett square can be used for each trait separately. Since one parent is homozygous dominant for both traits and the other is homozygous recessive, all offspring (F1 generation) will be heterozygous (BbTt) for both traits, displaying the dominant phenotypes: colored body and blue tail.
If two of the F1 heterozygous Betta fish (BbTt) are crossed, the resulting F2 generation will exhibit a variety of genotypes. The traits segregate independently, following Mendelian genetics patterns, which indicate a 9:3:3:1 phenotypic ratio for the two traits when F1 individuals mate.
Therefore, the chance of an offspring that is white with a blue tail (bbT-) will be calculated by determining the probability of the offspring being homozygous recessive for body color (bb) and having at least one dominant allele for tail color (T). This corresponds to 1/4 being homozygous recessive for body color multiplied by 3/4 having a blue tail (since both Tt and TT result in a blue tail), which equals 1/4 * 3/4 = 3/16, or about 18.75%.
Transition step:
Each pyruvic acid molecule is transported to the ____________
A one carbon molecule called _____ is released from each molecule of pyruvic acid and the remaining 2-carbon unit that is formed is called ________.
CoenzymeA is then attached to _ ____ to form ____________.
Additional energy is stored as reduced ______ molecules
Answer: mitochondrion, carboxylic group , acetyl group, acetyl group, acetyl CoA, NADH
Explanation:
Two pyruvate molecules remain at the end of glycolysis which still have a lot of extractable energy. The next step in storing the remaining energy in the form of ATP is oxidation by pyruvate. The transition steps are as following:
Pyruvate must join the mitochondrion, cross its inner membrane and arrive at the matrix before the chemical reactions can begin. A group of carboxyl (one carbon molecule) is snipped off of pyruvate and released as a carbon dioxide molecule, leaving behind a two-carbon molecule called the acetyl group. The oxidised two-carbon molecule, acetyl group attached to Coenzyme A to form acetyl CoA.The additional energy during conversion is reduced NADH molecules and two carbon dioxide molecule.Hence the correct order to fill the blanks is mitochondrion, carboxylic group , acetyl group, acetyl group, acetyl CoA, NADH.

Because they often survive at extreme temperatures, _______ are thought you have been the first organisms on the early earth
Answer:
Extremophiles
Explanation:
Extremophiles are organisms that have been discovered on Earth that survive in environments that were once thought not to be able to sustain life. These extreme environments include intense heat, highly acidic environments, extreme pressure and extreme cold. Different organisms have developed varying ways of adapting to these environments, but most scientists agree that it is unlikely that life on Earth originated under such extremes.

Explain Mendel’s laws in genetic terms, that is, in terms of chromosomes, genes, and alleles.
Answer:
Law of segregation is when two genes control the alleles and those two genes go to two different chromosomes. Law of independent assortment is when two genes control the alleles and are inherited independently.
Explanation:
Mendel’s laws in genetic terms, that is, in terms of chromosomes, genes, and alleles states that the genes activity along with the expressions that they express within the progeny.
What is a gene ?It is defined as unit of inheritance that states that gene basically controls the expression of the character and pass on through chromosome.
Mendel's law of independent assortment states that the chromosomes express themselves individually that the genes are expressed independently in the process of inheritance in the progeny.
Law of segregation says that the genes gets segregated before passing on to their progeny before expressing they assort independently and segregate as such in the progeny.
Mendel's law of segregation is the first division of meiosis in which the homologous chromosomes with their different versions of each gene are segregated into daughter nuclei.

Distance runners include aerobic training as part of preparation for races. How does this impact their cellular respiration?
Answer and Explanation:
Running or jogging comes under the category of aerobic training/exercise. By definition, aerobic exercise means that the person is training her/his body in the presence of excessive oxygen. So, metabolically speaking, the person is relying on availability of oxygen to carry out metabolism which is mainly about production/supply of energy (ATP) by the breakdown of food in the presence of oxygen. This process is also known as cellular respiration. So, if a person is doing aerobic exercise (running), s/he needs more energy to keep doing the exercise. Typically, aerobic exercise produce more energy (32 molecules of ATP) as compared to anaerobic process (2 molecules of ATP) per reaction run. Thus, In the process of aerobic exercise, the lungs will respire faster to allow more diffusion of oxygen in the blood. Then, this oxygen will be transported to all body by heart pumping and then oxygen enters the cells. Once oxygen is entered, it acts as terminal electron acceptor in a process known as oxidative phosphorylation. This process takes plance in the mitochondria and produces 32 molecules of ATP per reaction.
What is the genotype of the offspring
The genotype of the offspring is likely heterozygous (Bb), with one black feather allele (B) and one white feather allele (W).
In genetics, the color of chicken feathers is often determined by multiple alleles at a single gene locus.
Let's use the letter "B" to represent the allele for black feathers and "W" for white feathers.
Since the chicken with black feathers is denoted as BB and the one with white feathers as WW, we can infer that black feathers (B) are dominant over white feathers (W).
When these two chickens are crossed, the resulting offspring will inherit one allele from each parent.
The genotype of the offspring will be BW, indicating that they carry both a black allele (B) from one parent and a white allele (W) from the other parent.
Despite having both alleles, the phenotype, or the observed trait, is black feathers, as the black allele is dominant.
In a more detailed explanation, the genotype of the offspring can be heterozygous (Bb), with one black allele and one white allele.
However, since black is the dominant trait, the presence of the black allele will determine the phenotype.
This type of genetic cross, involving a dominant and a recessive allele, results in a phenotypic expression that reflects the dominant allele's characteristics.
