Answer:
The correct answer is NMDA receptor acts as a molecular coincidence detector.
Explanation:
The hippocampus works entirely for memory processes (especially new learning). Lasting depression (LTD) is also considered as another form of expression of synaptic plasticity. Long-term potential occurs when pyramidal neurons are depolarized and stimulated by excitatory input. The neurophysiological basis for LTP is certainly related to a subtype of NMDA of the glutamate receptor. This receptor behaves as a coincidence detector between pre- and post-synaptic activity, with an increase in glutamate release at the presynaptic level coinciding with a Postsynaptic depolarization that allows the entry of ca2 +. The NMDA receptor has been proposed as the basic mechanism of learning, because it has the ability to associate different signals, for all this it is necessary to know what neurotransmitters are, their function and what is the role of the receivers in them.

Answer:
The correct answer is ''The scientific study of heredity''
Explanation:
Genetics is a branch of biology that studies how hereditary characters are transmitted from generation to generation and the diversity that exists among living beings. Inheritance is the physical and biological characteristics that we share with our family and that can determine our appearance and our biological characteristics, that is, our phenotype (eye color, skin type, etc.) as well as our internal characteristics. All of this is largely derived from our genetic components, that is, our genotype.

i) predict which of the liquids would cause the largest decrease in mass of potato stick
PLEASE PLEASE HELP ME I HAVE 10 MINUTES ONLY, I WILL GIVE YOU THE BRAINLIEST!!
Answer:
1 mol per dm3 sodium chloride solution
Explanation:
The liquid that would cause the largest decrease in the mass of the potato stick would be the one with 1 mole per dm3 sodium chloride solution.
The water potential of a solution depends on the molarity of the solution, the higher the molarity, the lower the water potential and vice versa. Hence, a solution with higher molarity has the tendency to osmotically draw more water from the potato stick than a solution with lower molarity.
Therefore, the potato stick will have the largest decrease in mass in 1 mol per dm3 sodium chloride when compared to the 0.5 and 0.1 mole per dm3 solutions.

Which of the following is one of the ways that cellular respiration and
photosynthesis are opposite processes? *
•Photosynthesis releases energy, and cellular respiration stores energy.
•Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration
puts it back.
•Photosynthesis removes oxygen from the atmosphere, and cellular respiration puts it
back.
•Photosynthesis consumes glucose, and cellular respiration produces glucose.
Answer:
•Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.
Explanation:
Photosynthesis:
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
Carbon dioxide + water + energy → glucose + oxygen
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.
Cellular respiration:
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
In this way it release the carbon dioxide back into atmosphere.
What is the probability of the offspring having brown eyes (dominant) if the father has the "bb" genotype and the mother has the "BB" genotype? You must create your own Punnett Square. *
Answer:
1 or 100%
Explanation:
Assuming that the allele B (brown) is dominant over the allele b, crossing the father and the mother:
BB x bb
Bb Bb Bb Bb (you can also see the Punnet's square)
All the offspring would exhibit the dominant phenotype which is brown. Hence, the probability of the offspring having brown eyes is 100% or simply 1.
Which of the following senses is mediated by mechanoreceptors?
A. Sight
B. Taste
C. Hearing
D. Smell
Hearing is the sense mediated by mechanoreceptors.
Mechanoreceptors are a type of receptors involved in the perception of:
Changes in the temperature.Movement.Vibrations or sounds.Pressure.One of the senses that is directly related to these receptors is hearing because this sense involves the perception of sounds through vibration or waves.
In this way, every time there is a sound the mechanoreceptors located in the ear perceive this sound and translate these waves into neural signs, which is necessary for the hearing process.

For this activity, you will be creating your own Mad Libs game. It’s similar to the way you created the Introduction paragraph in the unit.
Start by typing out your Mad Libs fill-in-the-blank story in a word processing document. Make it as creative as possible! Identify whether your blanks should be filled by nouns, verbs, adjectives, or adverbs. Your story should include at least 10 blanks.
Next, transform your story into one big Python print statement in OnlineGDB using variables in place of the blanks.
Finally, create the variables you need for your template by putting them at the top of your program. You should use input statements to make the game interactive.
Test out your program thoroughly, fixing any syntax errors or bugs that arise.
Copy and paste the link to your code into the same document where you wrote your fill-in-the-blank story so that you have the regular fill-in-the-blank version and the code version.

Explanation:
Complete the Punnett square below by showing the genetic makeup of the parent plats of the cross shown.Be sure to show both genes for each parent.
Answer:
The correct answer is -
Parent 1: RW, Parent 2: RR
Explanation:
In the given punnet square there are four offspring and it is a monohybrid cross between parent 1 and parent 2. The four offspring produced in this cross have RR, RR, RW, and RW alleles. By the genotype of the offsprings, it is clear that there are 50 percent pure or true-bred and 50 percent are heterozygous.
Each parent contribute two alleles and these alleles are independently assort in the zygote to form offspring so there must be R, R, R and W allele present in the parent
Parent 2 → R R
Parent 1 ↓ R RR RR (one allele (R) come from each parent in zygote)
W RW RW (one allele (R and W) come from each parent)

the chart below lists substances involved in the process of photosynthesis
which statement best describes how these substances interact in photosynthesis
Answer:
C and D combine to produce A and B.
Explanation:
The chart you were given is shown in the image I attached below. The options you were given are the following:
A and B combine to produce C and D. C and D combine to produce A and B. B and C combine to produce A and D. A and C combine to produce B and D.Photosynthesis is a process in which organisms that possess the pigment called chlorophyll (most plants and some protists and bacteria) produce the energy necessary for their survival. With the help of sunlight, they convert water (D), carbon dioxide (C), and minerals into oxygen (B) and glucose (A).
This is why the second option is the correct one.
Answer:
c and d combined to produce both A and B
Explanation:
In a certain species of flowering plant, the purple allele P is dominant to the
Yellow allele p.
A student performed a cross between a purple-flowered plant and a
yellow-flowered plant. When planted, the 146 seeds that were produced from the
cross matured into 87 plants with purple flowers and 59 plants with yellow
flowers.
Calculate the chi-square value for the null hypothesis that the purple-flowered
parent was heterozygous for the flower-color gene. Give your answer to the
nearest tenth.
Answer:
3.4
Explanation:
If the purple flower is heterozygous:
Pp x pp
Pp Pp pp pp
the expected ratio of purple flower offspring to yellow flower offspring would be 50:50.
Chi square = [tex]\frac{(O - E)^2}{E}[/tex] where O = observed frequency and E = expected frequency.
phenotype O E Chi square
purple 87 73 [tex]\frac{(80-73)^2}{73}[/tex] = 0.67
yellow 59 73 [tex]\frac{(59-73)^2}{73}[/tex] = 2.68
Total = 0.67 + 2.68 = 3.35 to the nearest tenth = 3.4
Degree of freedom = 2 - 1 = 1
Critical Chi square value (alpha = 0.05) = 3.84
SInce the critical Chi square value is greater than the calculated value, the null hypothesis is accepted.
