Through birth, death or migration...so actually yes, your mom is a significant contributer.
Yes, tapeworms can lead to weight gain in individuals by absorbing nutrients from the host's digestive system, causing the host to lose weight despite eating more.
Evolution occurs at the population level, where selection happens to populations rather than individuals.
Temporal isolation between populations is caused by differences in the timing of reproductive activities, such as mating seasons or times of day when individuals are most active. This can prevent individuals from different populations from mating and producing offspring, leading to reproductive isolation.
Genetic distance between individuals or populations can be calculated by comparing the differences in their DNA sequences. This can be done by analyzing specific genetic markers or using advanced techniques like whole-genome sequencing. The more differences there are in the DNA sequences, the greater the genetic distance between the individuals or populations.
A scenario that causes gene flow is when individuals from one population migrate to and interbreed with individuals from another population, exchanging genetic material. This movement of individuals can result in the transfer of genes between populations, increasing genetic diversity and potentially altering the genetic makeup of both populations.
Yes, tapeworms can lead to weight gain in individuals by absorbing nutrients from the host's digestive system, causing the host to lose weight despite eating more.
Lose
Populations evolve, but individuals are selected. Natural selection affects individual organisms.
Populations evolve, individuals are selected.
Neither lose nor gain.
gain
Atoms typically do not lose protons because that would change the identity of the element. Instead, atoms can lose or gain electrons to form ions with a different charge. Protons are not generally lost by atoms in chemical reactions.
If you gain internal validity do you lose external validity
When atoms lose or gain electrons, they form ions. These are charged particles.
Most substances lose or gain energy when their temperature changes.
Wisdom.
if anything it would be reasonable to expect it to lose mass.
