Smaller neurons require more current to change their membrane potential.
a) true
b) false
This is false that Smaller neurons require more current to change their membrane potential.
A potential gradient known as membrane potential causes ions to passively migrate in one direction: positive ions are drawn to the "negative" side of the membrane, while negative ions are drawn to the "positive" side. Human life is impossible without membrane potentials. Over their membrane, every living cell maintains a potential difference. Simply said, differences in the concentration and permeability of significant ions across a membrane are what cause membrane potential.
A change in membrane potential results from a change in ion permeability. The membrane potential moves closer to the ion's Nernst equilibrium potential as permeability to that ion increases. The membrane potential is shifted away from the ion's Nernst equilibrium potential as permeability to that ion decreases.
The less probable it is that the arriving ions will collide with something that might cause them to bounce back, the bigger the axon's diameter of a neuron. Positive ions must continuously move away from the cell body in order for the action potential to exist, and this is made much simpler in a bigger axon.

after it is released a mature egg travels by the means of
Answer:
Muscle Contractions
*EDUCATIONAL PURPOSES*
Ovulation Process:
The pituitary gland, located in your brain, releases a hormone once every month. This hormone instructs the ovaries to create many follicles, which are fluid-filled cysts. The hormone oestrogen is secreted by the growing follicles. In order to prepare for pregnancy, oestrogen causes the uterine membrane to thicken.
The follicles cease developing on day seven of your cycle, with the exception of one. This follicle keeps expanding and nourishes an oocyte (egg) that is developing within.
On day 12, a surge of oestrogen is released into the bloodstream by the developing follicle. Your blood carries the oestrogen along. The pituitary gland in your brain releases luteinizing hormone in response to the oestrogen reaching it. This hormone causes a quick growth spike in the follicle.
The egg within the follicle separates from the follicle just before ovulation. The neighboring fallopian tube begins to migrate toward and around the follicle as the follicle begins to produce chemicals.
The egg and fluid are ejected into the abdominal cavity when the follicle expands to the point of breaking open.
Fimbriae, or tiny finger-like projections at the termination of the fallopian tube, move over the ruptured follicle and seize the egg.
The egg is moved to the fallopian tube's opening. Muscle contractions push the egg gently towards the direction of the uterus once it has entered the fallopian tube's walls.
Either sperm will contact the egg as it travels down the fallopian tube, resulting in fertilization, or the egg will arrive in the uterus unfertilized and be reabsorbed into the body.
Conception Process:
A woman must fertilize her egg within the 12 to 24 hours following ovulation if she wants to get pregnant.
The surge of oestrogen right before ovulation also creates the protein-rich transparent jelly that covers the vagina during intercourse within the neck of the uterus (the cervix). Thus, the vagina became acidic (which prevents thrush and other infections). Sperm can survive in this environment as well. Rapidly moving sperm swim up and into the cervix, where they can live for up to five days in the mucus until an egg is produced.
The fallopian tube might grab the egg because it is wrapped in sticky cells when it is released after ovulation. The sperm begin to break down the adhesive cells when they encounter the egg in the fallopian tube. While only one sperm is required to create a baby, numerous are required to cling to the egg's membrane and outer shell before one may penetrate and fertilize it.
After fertilization, substances are produced to prevent the entry of more sperm before the egg and sperm swiftly combine and split to form an embryo.
The fertilized egg continues to divide and move toward the uterus throughout the course of the following four to five days.
The burst follicle (now known as the corpus luteum), which releases the hormone progesterone into your bloodstream, primes the uterus for the egg to implant.
The pregnancy is sending an increasingly potent signal to the ovary to prolong and boost the production of progesterone, which the pregnancy needs to live, while it develops and installs itself into the mother's uterine lining and blood vessels.

Why does venous return from the distal arm travels in the superficial veins and those veins tend to bulge superficially in a person who is working out?
Blood distribution is adjusted by a short-term neural control mechanism to meet specific demands. During working out, the hypothalamus signals for reduced vasomotor stimulation of the skin vessels. Blood moves into the capillary veins, and heat radiates from the skin to reduce body temperature.
VeinsAll over your body, veins are blood vessels that collect blood with low oxygen content and send it back to your heart. Your circulatory system includes your veins. They cooperate with your heart, other blood vessels, and other organs to maintain blood flow. Most of your body's blood is stored in veins. Your veins actually contain around 75% of your blood. Veins have two basic functions. One function is to gather blood that is low in oxygen throughout your body and transport it back to your heart. The other function is to transport blood that is rich in oxygen from your lungs to your heart. Only during this process do veins transport oxygen-rich blood.

Disease that is characterized as having lack of energy and protein is called?
Answer:
Sounds closest to: Kwashiorkor
Explanation:
Kwashiorkor is a disease brought on by severe protein malnourishment. In Kwashiorkor, extended breastfeeding and late, insufficient weaning lead to low calorie intakes but significantly superior biological value. As a result, a kid with kwashiorkor will likely experience compromised organ function and development. Sudden outbreaks of diseases like the measles, gastroenteritis, or pneumonia exacerbate the issue by increasing needs while maintaining low intakes. The kid may exhibit oedema of the face and lower limbs, failure to grow, anorexia, diarrhea, lethargy, dermatosis, flaky-looking skin, scant, soft, and thin hair, angular stomatitis, cheilosis, and anemia as a result of this scenario.
This is a bit similar to Marasmus.
But there is a difference.

What are the two major modes of glycolysis and what is the purpose of each mode?
The two major modes of glycolysis are aerobic and anaerobic glycolysis.
Glycolysis is the method by which glucose is broken down to produce energy. It generates two pyruvate molecules, ATP, NADH, and water. There is no need for oxygen throughout the process, which occurs in the cytoplasm of a cell.
Both anaerobic and aerobic conditions can result in glycolysis.
Pyruvate enters the citric acid cycle under aerobic conditions and proceeds through oxidative phosphorylation, which results in the net synthesis of 32 ATP molecules. Pyruvate is converted to lactate in anaerobic conditions by anaerobic glycolysis. During anaerobic respiration, two ATP molecules are produced.

Introduction of an oxytocin-like drug
Introduction of a viral vector that increases oxytocin receptor density in the reward pathway
Introduction of an oxytocin blocker
Upregulation of vasopressin and oxytocin in the spinal cord using a microcatheter
Upregulation of vasopressin and oxytocin in the spinal cord using microcatheter interventions could increase monogamy among meadow voles. the correct answer is option(e).
In contrast to non-monogamy, monogamy is a type of dyadic interaction in which an individual has only one partner during their lifespan or, alternatively, just one partner at any given moment. The phrase is also used to describe how some animals behave in social situations, specifically the status of having just one mate at any given time.
Inhibitory interneurons may be activated by oxytocin and vasopressin across subcortical and possibly cortical networks, including reward pathways, to moderate their effects. Brain areas that are important for maintaining behavioral and physiological equilibrium are where oxytocin and AVP are largely produced.

The equation of the least-squares line for predicting tail length from weight is: predicted tail length = 20 + 3 × weight .
Determining how variation in morphology affects animal performance (and ultimately fitness) is key to understanding the complete process of evolutionary adaptation. Long tails have evolved many times in arboreal and semi-arboreal rodents; in deer mice, long tails have evolved repeatedly in populations occupying forested habitat even within a single species (Peromyscus maniculatus).
We use a combination of functional modeling, laboratory studies, and museum records to test hypotheses about the function of tail-length variation in deer mice.
First, we use computational models, informed by museum records documenting natural variation in tail length, to test whether differences in tail morphology between forest and prairie subspecies can influence performance in behavioural contexts relevant for tail use. We find that the deer- mouse tail plays little role in statically adjusting centre of mass or in correcting body pitch and yaw, but rather it can affect body roll during arboreal locomotion.
In this context, we find that even intraspecific tail-length variation could result in substantial differences in how much body rotation results from equivalent tail motions (i.e., tail effectiveness), but the relationship between commonly-used metrics of tail-length variation and effectiveness is non-linear.
