An atom is the smallest particle of a substance that has all the properties of the substance.
Every atom is composed of a nucleus and one or more electrons which are bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons as well. Only the most common variety of hydrogen has no neutrons in it.
The electrons of an atom are attracted to the protons in an atomic nucleus through the electromagnetic force. The protons and neutrons in the nucleus are attracted to each other with the help of nuclear force. This force is usually stronger than the electromagnetic force which repels the positively charged protons from one another in the nucleus. Under certain circumstances, the repelling electromagnetic force between protons become stronger than the nuclear force. In this case, the nucleus splits and leaves behind different elements. This is a type of nuclear decay.

B. Logistic growth
C. Emigration
D. Immigration
Answer: C. Emigration
Explanation:
Young animals approaching maturity might do emigration, to find mates or to establish new territories. Emigration can be define as the migration or departure of individuals from their native land to the new land. The organisms usually find a suitable location where resources such as food, water and mates are available for copulation and reproducing offsprings. The increase in the population of the emigrant organisms help it to maintain their own territories against the competing members of the same population.
Answer:
Genetic factor
Explanation:
Height is the trait that is regulated by genetic and environmental factors. The type of the gene present in the genome of the organism and environmental factors such as nutrition, physical activity, surroundings etc. regulate the height of the organisms. If environmental factors are kept constant, the height would be regulated by genetic factors only.
The frog's vestigial thumb may provide some vestigial functions like clinging or handling prey. Like opposable thumbs in primates, it's a remnant from evolution, and may aid in survival-oriented activities or serve no current significant purpose.
The frog's vestigial thumb, much like opposable thumbs in primates, is believed to be a trait left over from previous evolutionary stages. While its function in frogs is not fully understood, it is suggested that vestigial structures like the thematic thumb could still retain some functional or minimal purpose, potentially related to clinging or handling prey. For example, in primates, the opposable thumbs and toes are an adaptive trait providing the ability to effectively grasp branches, cling onto surfaces, and hold objects which contributes vastly to their survival in arboreal environments.
Although in frogs the thumb likely doesn't grant the same mobility or dexterity as in primates, its presence may still aid in activities like feeding, movement, or escaping from predators. Also, it's important to note that not all traits are formed for survival or adaptive purposes and could be neutral or nonadaptive, serving no current significant function or benefit.

It consist of two fatty acids, a glycerol molecule and a phosphate group that is controlled by an alcohol. Usually the phosphate group is the negatively charged polar head, making it hydrophilic. The fatty acids are chains of uncharged and non polar tails which makes these hydrophobic.
Answer:
Nonpolar and Hyrdrophobic
