What factor is described as sexual
selection?
A, non-random mating
B. migration
C. small populations
D. natural selection
Answer:
The correct answer is - D. natural selection.
Explanation:
Sexual selection takes place due to competition between individuals of the intraspecies same-sex and of mate choice which driving the evolution of reproductive traits.
Sexual selection is a mode of natural selection as it leads to the evolution of specific traits. Other examples or options are not related to sexual selection directly and are not affected by sexual selection.

Explanation:
vacuoles help maintain water balance.
Explanation:
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.
In general, the functions of the vacuole include:
Isolating materials that might be harmful or a threat to the cell.
Containing waste products.
Containing water in plant cells.
Maintaining internal hydrostatic pressure or turgor within the cell.
Maintaining an acidic internal pH.
Containing small molecules.

hello.................................................,.....what's a vaccine.thankyou
A vaccine is a medical material that mimics the pathogen, but in a harmless way. When our body's immune fights it off, it remembers how to fight the real pathogen when it enters our body. So, it protects us from diseases.
Answer:
A vaccination is a medical substance that mimics a pathogen in a non-harmful way. When our immune system defeats it, it recalls how to combat the genuine infection when it enters our system. As a result, it shields us against sickness.

Fruit trees in a forest are an important habitat for a bird species and were historically a major source of food for a rodent species. Over time, the rodent species shifted their feeding behavior from fruit trees to nut trees. As rodent behavior changed, the density of fruit trees decreased, which caused significant decreases to the bird population. What kind of effect did the change in rodents exert on bird population size?
Answer:
The bird population might have to migrate in search for food or may decline in numbers.
Explanation:
This is a concept of primary producers that is trees and secondary consumers that is mouse and bids. Due to the decline in raw material available the mouse population declines and this also affects the secondary consumers that are birds of prey like hawks, owls etc.I can't understand this sentence structure, so if somebody could please help me and have the right answers I will give brainliest.
what is photosynthesis
Answer:
Photosynthesis is where the plants take in food through the cells! (such as light and carbon dioxide.)

la unica fuente de los aminoacidos esenciales son los alimentos y su anotemcion requiere de un gran gasto emergetico.si uma persona no consume estos aminoacidos se vera afectado el paso
Answer:
Los aminoácidos son compuestos orgánicos que se combinan para formar proteínas. Los aminoácidos y las proteínas son los pilares fundamentales de la vida.
Cuando las proteínas se digieren o se descomponen, los aminoácidos se acaban. El cuerpo humano utiliza aminoácidos para producir proteínas con el fin de ayudar al cuerpo a:
Descomponer los alimentos
Crecer
Reparar tejidos corporales
Llevar a cabo muchas otras funciones corporales
El cuerpo también puede usar los aminoácidos como una fuente de energía.

\Which best describes dynamic equilibrium?
There is a difference in concentration on either side of the cell membrane.
There is an uneven distribution of particles inside and outside the cell.
Particles are moving into and out of the cell, but their concentrations remain stable.
A concentration gradient is forcing water out of the cell and particles into the cell.
Answer:
The answer is C - Particles are moving into and out of the cell, but their concentrations remain stable.
Explanation:
Particles are moving into and out of the cell, but their concentrations remain stable.
Particles are moving into and out of the cell, but their concentrations remain stable.
What is dynamic equilibrium?Dynamic equilibrium is a state of balance in which two or more opposing forces or processes are in constant motion, resulting in a stable overall state. In biology, dynamic equilibrium often refers to the balance of substances, such as ions or gases, between two or more compartments, such as inside and outside of a cell.
This balance is maintained by the movement of these substances across a semi-permeable membrane in response to concentration gradients, pressure, or other driving forces. The rate of movement into and out of the compartment is equal, resulting in no net movement of substance and a stable concentration on both sides.
Dynamic equilibrium is an important concept in understanding the maintenance of homeostasis and the proper functioning of biological systems.

What conditions need to be present for an atom to form hydrogen bonds?
For an atom to form hydrogen bonds, it needs to be bonded to a highly electronegative atom (such as nitrogen, oxygen, or fluorine) and have a hydrogen atom attached to it.
Hydrogen bonds are intermolecular forces that occur between a hydrogen atom bonded to a highly electronegative atom and another electronegative atom nearby. The highly electronegative atom, often nitrogen (N), oxygen (O), or fluorine (F), attracts the shared electrons in the covalent bond towards itself, creating a partial negative charge. This leaves the hydrogen atom with a partial positive charge.
The conditions necessary for hydrogen bonding to occur are:
Presence of a Hydrogen Atom: There must be a hydrogen atom (H) bonded to an electronegative atom (N, O, or F) in the molecule or adjacent molecules.Highly Electronegative Atom: The electronegative atom (N, O, or F) must have a strong attraction for electrons, creating a significant partial negative charge.Close Proximity: The electronegative atom with the partial negative charge must be close enough to another electronegative atom in another molecule or nearby region to allow for electrostatic attraction.These conditions are essential for the formation of hydrogen bonds. The hydrogen bond itself is a relatively weak force compared to covalent or ionic bonds, but it is significant in biological systems and plays a crucial role in many biological processes. Hydrogen bonding contributes to the unique properties of water, the stability of protein structures, the binding of DNA strands, and various other molecular interactions.
In summary, for an atom to form hydrogen bonds, it must be bonded to a highly electronegative atom (N, O, or F) and have a hydrogen atom attached to it, with another electronegative atom in close proximity to allow for the formation of electrostatic interactions.
