visceral reflex arcs do not control: question 24 options: blood pressure. heart rate. digestion. voluntary muscle functions
Answers
Visceral reflex arcs do not control voluntary muscle functions.
Visceral reflexes necessitate a glandular or non-skeletal muscular reaction performed in internal organs like the heart, blood vessels, or structures of the GI tract.
To elicit their actions, they use neurons of the autonomic nervous system. Sneezing, coughing, swallowing, vomiting, pupil dilation, and contraction of smooth muscles of hollow organs in various organ systems are examples of visceral reflexes.
The autonomic nervous system branch of the visceral reflex arc commences with the central neuron's projection along the preganglionic fiber. This fiber then connects to a ganglionic neuron and projects to the intended effector.

what factors are responsible for increasing the size of a population?
Answers
Answer:
Economic development
Explanation:
1. Natural increase: This refers to the difference between the number of births and the number of deaths in a population. If the number of births is greater than the number of deaths, the population will grow.
2. Immigration: If people move into a population from other areas, it can contribute to population growth.
3. High fertility rates: A high fertility rate, or the average number of children a woman has during her reproductive years, can also contribute to population growth.
4. Increased life expectancy: If people are living longer due to advances in medicine and public health, the population will grow.
5. Changes in social norms: Changes in social norms, such as the acceptance of smaller families, can also impact population growth.
It's worth noting that population growth is not always a positive thing, as it can put strain on resources and the environment. Some countries have implemented policies to encourage smaller families and slow population growth.

Describe two effects that a change in the sequence of amino acids would have on a protein.
Answers
Intricate molecules make up proteins.
The way a protein folds up determines the distinct three-dimensional form that it has. It cannot do its task in the cell if it does not fold up into the proper shape. Amino acid linkages, which are dispersed along the protein molecule, are what give a protein its shape. The bond cannot form if the incorrect amino acid is present, preventing the protein from adopting the proper shape and performing its function. For instance, the illness sickle cell anemia is brought on by a single fatal error in the amino acid sequence of the hemoglobin molecule!
Proteins are made from chemical 'constructing blocks' called amino acids. Your body uses amino acids to construct and repair muscle mass and bones and to make hormones and enzymes.

You are examining the data from two time points taken in an experiment. At time 1 there was an extracellular concentration of Na of 115 mM outside the cell and 8mM inside the cell. An amino acid, lycine, is at 20mM outside and 40mM inside. At the second time measured Na is 100mM outside the cell and 23 mM inside the cell. Lycine is 15 mM outside the cell and 45mM inside. What is the best explanation
Answers
Answer:
See the answer below
Explanation:
The best explanation would be that both Na and the amino acid lycine are simultaneously diffusing (in bound form) from the outside to the inside of the cell.
Considering the Na alone, one would see that the concentration outside the cell decreased in equal amount (15 mM) as the increase in the intracellular concentration of the same molecule.
Also considering the amino acid alone, the extracellular concentration increased by the same magnitude (5 mM) as the decrease in the intracellular concentration of the same molecule.
Hence, it could only be that both molecules bind together and diffused from the region of higher concentration (outside of the cell) to the region of lower concentration (inside).

which of the following processes could occur only through the plasma membrane of a living cell
Answers
The process that could occur only through the plasma membrane of a living cell is selective permeability.
Selective permeability is a key function of the plasma membrane, allowing certain substances to pass through while preventing others. This helps maintain homeostasis within the cell by regulating the exchange of substances, such as ions, nutrients, and waste products.
The plasma membrane consists of a phospholipid bilayer embedded with proteins, which play a crucial role in selective permeability. Some of these proteins act as channels or carriers, facilitating the passage of specific molecules or ions. Others function as receptors, detecting signals from the environment and initiating a response within the cell.
Passive transport, such as diffusion and osmosis, involves the movement of substances down their concentration gradient without the use of energy. In contrast, active transport requires energy to move substances against their concentration gradient, often utilizing ATP as the energy source.
In summary, selective permeability is the process that occurs exclusively through the plasma membrane of a living cell, enabling the regulation of substance exchange and maintaining cellular homeostasis. This is achieved through a combination of passive and active transport mechanisms, facilitated by the proteins embedded within the phospholipid bilayer of the plasma membrane.

Compare and Contrast Differentiate between DNA replication in prokaryotes and DNA replication in eukaryotes.
Answers
The basic process of DNA replication is similar in prokaryotes and eukaryotes, but there are significant differences in the details of how replication occurs in these two types of organisms.
What is DNA replication?
DNA replication is a fundamental process that is essential for the survival and reproduction of all living organisms.
While the overall mechanism of DNA replication is conserved between prokaryotes and eukaryotes, there are some key differences in the way that DNA replication occurs in these two types of organisms.
Here are some of the differences between DNA replication in prokaryotes and DNA replication in eukaryotes:
DNA polymerases: In prokaryotes, DNA replication is carried out by DNA polymerase III. In eukaryotes, DNA replication is carried out by multiple DNA polymerases.
Origin of replication: Prokaryotes have a single origin of replication on their circular chromosome, while eukaryotes have multiple origins of replication on their linear chromosomes.
Chromosome structure: Prokaryotes have a single circular chromosome that is not associated with histones, while eukaryotes have multiple linear chromosomes that are tightly packed with histone proteins.
Replication speed: Prokaryotes replicate their DNA much faster than eukaryotes.
Proofreading: Eukaryotic DNA polymerases have a built-in proofreading mechanism that can detect and correct errors in the newly synthesized DNA. In contrast, prokaryotic DNA polymerases do not have this proofreading ability and instead rely on a separate repair mechanism to correct errors after replication has occurred.

Answers
Soil pH level characteristic of soil will most accurately check the suitability of land for growing berries
The soil pH level is the most important characteristic to check the suitability of land for growing berries. Berries generally thrive in slightly acidic soil with a pH level between 5.5 and 6.5. If the soil pH level is too high or too low, it can lead to nutrient deficiencies, poor plant growth, and low yields. Therefore, it is crucial to test the soil's pH level before planting berries to ensure the best growing conditions and maximum profits. Other characteristics such as soil texture, drainage, and nutrient content also play a significant role in berry cultivation but the soil pH level is the most critical factor to consider.

A Frisbee is rolling smoothly down a hill with a rotational kinetic energy of 30 Joules. What is the most reasonable approximation for its translational kinetic energy
Answers
The Frisbee's translational kinetic energy is approximately 15 Joules.
To calculate the translational kinetic energy of the rolling Frisbee, we can use the concept of the parallel axis theorem, which states that the total kinetic energy of a rotating object is the sum of its rotational and translational kinetic energies.
Given:
Rotational kinetic energy (\(K_{rot}\)) = 30 Joules
The translational kinetic energy (\(K_{trans}\)) can be approximated by dividing the rotational kinetic energy by a factor of 2:
\(K_{trans}\) = \(K_{rot}\) / 2
= 30 Joules / 2
= 15 Joules
Therefore, the most reasonable approximation for Frisbee's translational kinetic energy is 15 Joules. This approximation assumes that the rolling motion of the Frisbee is smooth and there are no other significant factors affecting its energy distribution.

The Correct answer would be an element with a high electronegativity and with a single valence electron.
Explanation:
Atoms need 8 electrons in their outershells to be stable. If they don't have eight, they will try to borrow from other atoms. So if an atom only needs one more electron, think of it as being desperate and highly reactive. When an atom with only one valence electron (electron in the outershell) comes along, it's the easiest victim to borrow off of.
