#1 The subatomic particle that is neutral is the _____.
#2 A (An) _____ is a negatively charged particle
#3 According to modern atomic theory, _____ can't move from one energy
level to another.
The subatomic particle that is neutral is the Neutron. (An) electron is a negatively charged particle
According to modern atomic theory, the proton can't move from one energy level to another
With the work of the English chemist John Dalton, the current atomic theory, which has continuously undergone refining, started to blossom at the beginning of the 19th century.
The modern atomic theory holds that atoms are no longer indestructible and now contain electrons, protons, neutrons, and other sub-particles. Isotopes are variations of an element's atoms that can exist.
The concepts of atoms and how they create matter are established by current atomic theory. Atoms are composed of negatively charged electrons revolving around a core nucleus made up of electrically neutral neutrons and more massive positively charged protons.

Which of the following population rates is most affected by the species' gestational period?
Birth
Death
Emigration
Immigration
The correct answer is Birth.
The two elements that raise population size are natality—the number of people who are added to a population over time as a result of reproduction—and immigration—the movement of people into a location. Most births are to folks who are young adults or older. Even at replacement fertility levels (when each woman has approximately an average of two children), there will be more births than deaths if the proportion of young adults to older adults is higher where mortality is highest. Immigration and birth rates lead to population growth. The population shrinks as a result of death rates and emigration. A population that has a negative growth rate is one in which there are more deaths and emigrants than births.

Dinobryon is a species of protozoa that reproduces asexually ?
They have less genetic diversity in their population.
Asexual reproduction and genetic diversitySexual reproduction involves genetic recombination and as such, produces genetically more variable offspring.
This is unlike asexual reproduction. There is no form of genetic recombination whatsoever. All the offspring have the same genomes as the parents.
When a population is genetically diverse, such a population will be able to adapt to changes in their environment more quickly.
A population that has little to no genetic diversity can get wiped out by a little change to the environment.
Thus, asexual reproduction can be advantageous in that reproduction is quicker and consumes less energy. However, it makes the population to be susceptible to elimination by environmental changes.

stimulates cells in the collecting duct.
O b) one regulates the blood concentration of
sodium, and the other does not.
O c) one regulates the blood concentration of
potassium, and the other does not.
Antidiuretic hormone (ADH) and aldosterone are different in that they stimulate cells in the distal convoluted tubule and the other stimulates cells in the collecting duct.
a) stimulates cells in the distal portion convoluted tubule and the other stimulates collecting duct cells.What is the difference between antidiuretic hormone (ADH) and aldosterone?Another distinguishing point between the two hormones is their place of action. “While aldosterone acts, using a simplified renal physiology, in the ascending region of the Loop of Henle and, with that, ends up causing water reabsorption in the renal tubules, ADH acts in the collecting duct, also promoting water reabsorption.”
With this information, we can conclude that Anti-diuretic hormone helps to control blood pressure by acting on the kidneys and the blood vessels. Its most important role is to conserve the fluid volume.

Codominance is an inheritance pattern. Human blood type is an example of CODOMINANCE where both the A and B blood types can be expressed.
What is codominance?Codominance refers to the inheritance pattern in which a phenotype expresses two alternative variants coded by two alleles inherited from each homozygous parent.
When two individuals, that are homozygous and different for a trait, are crossed they produce heterozygous individuals.
These progenies express both parental phenotypes, as it is an additive expression of their parents' genes. Both alleles are equally expressed.
The is not complete dominance in these cases.
In the case of blood, the I gene determines the blood type of a person.
→ I is completely dominant over the i recessive allele.
→ Allele I can be either IA and IB, which are codominant.

Quarks make up protons and neutrons that make up an atom's nucleus. Each proton and each neutron contains three quarks. The particle that carries the strong force is called a gluon, so-named because it so tightly "glues" quarks together into larger particles. Electromagnetic force is the force of attraction that is present between all objects. This force of attraction make them attached to one another.
Subatomic particles are electrons which is negatively charged and the positively charged protons and the electrically neutral neutrons.
An elements atomic number will never change but atomic mass can change that we call these isotopes. The atomic mass is the sum of the protons and neutrons in the nucleus. In an isotope you have more neutrons than you have protons.

True or false? Genes that are very far apart from one another on the same chromosome may be indistinguishable from genes on separate chromosomes in genetic linkage studies.
O True
O False
This is true that Genes that are very far apart from one another on the same chromosome may be indistinguishable from genes on separate chromosomes in genetic linkage studies.
The probability of two genes inheriting together increased depending on how close they were to one another on a chromosome. On the other hand, genes on the same chromosome that were more apart from one another were more likely to be split apart during recombination.
Every time a pair of genes on a chromosome that far apart crosses over, an equal number of parental and recombinant chromosomes are created.
Linkage is the propensity for genes on the same chromosome to pass down their mutations together.
Unlinked genes refer to genes that are spread across various non-homologous chromosomes.
