Answer: Punnett Squares take each of the possible alleles that the parent can pass down and predicts all possible outcomes for the offspring
Explanation:In this example, let’s set the trait for hair color (this is not a real example, it's hypothetical).Capital A is for blonde hair (its dominant)Lowercase a is for brown hair (it's recessive)In the above Punnett square, both parents are heterozygous- they have one Allele for blonde hair and one allele for brown hair. Since blonde hair is dominant, they both have blonde hair.In this Punnett square, 2/4 (50%) of the offspring will have the genotype Aa. This will present itself in the phenotype of blonde hair.1/4 (25%) of the offspring will have the genotype AA, which is homozygous for blonde hair.Lastly, 1/4 (25%) of the offspring will have the genotype aa, and this is homozygous recessive for brown hair.A Punnett square makes this much easier to visualize.
select the part whose main job is to sort and package proteins and other substances in an animal cell.
The part of the cell responsible for sorting and packaging proteins and other substances in an animal cell is the Golgi apparatus.
The Golgi apparatus, also known as the Golgi complex or Golgi body, is a stack of flattened membrane-bound sacs that are found near the cell nucleus. It receives proteins and other molecules from the endoplasmic reticulum and sorts them into vesicles, which are then transported to their destination within or outside of the cell. The Golgi apparatus is essential for the proper functioning of the cell, as it allows the cell to produce, modify, and distribute a wide variety of molecules.

the phenonmenon in which individuals lose their identity and relinquish normal restraints when they are part of a group is called
People who experience deindividuation lose their awareness of their socially constructed individual identities and turn to antisocial and anti-social behaviour.
One of the most frequently mentioned impacts of social groups is deindividuation, which is a condition of lower self-evaluation in a group. Deindividuation is a phenomena when people act in ways that appear impulsive, abnormal, and occasionally aggressive when they feel they can't be individually identified (e.g., in groups and crowds and on the Internet). The American social psychologist Leon Festinger first used the term "deindividuation" in the 1950s to refer to circumstances where individuals are unable to exist independently of one another. Due of the difficulty of locating or blaming individuals who are hidden inside a group, some deindividuated situations may result in a reduction in culpability.

Traits are frequently influenced by environmental factors rather than genetics. Although not always. Sometimes a gene's DNA sequence or degree of activity is altered by the environment.

a____process that takes place in a cell nucleus and that involves one cell duplicating and dividing.
Mitosis takes place in a cell nucleus and that involves one cell duplicating and dividing.
There are two types of cell division: mitosis and meiosis. When people talk about "cell division" they usually mean mitosis, the process of making new cells in the body.Meiosis is a type of cell division that produces egg and sperm cells .
Mitosis is a process fundamental to life. During mitosis, the cell replicates all its contents, including chromosomes, and divides to form her two identical daughter cells. This process is so critical that mitotic steps are carefully controlled by specific genes. Health problems such as cancer can occur when mitosis is not properly regulated.
Another type of cell division, meiosis, ensures that humans have the same number of chromosomes in each generation. This is a two-step process in which the number of chromosomes is halved from 46 to 23 to form sperm and eggs. When the sperm and egg cells combine at conception, each contributes her 23 chromosomes, so the resulting embryo is usually 46.

Wind turbines can generate a great deal of usable energy and have become popular because there is no cost to use wind and they do not emit greenhouse gases. A typical wind turbine is only 30% efficient though, and the other 70% of the energy slows down and moves towards the air, and transmits that energy into a rotating turbine to regenerate the electricity, or other mechanical operations (such as milling grain).
The most energy that can be extracted from flowing air by a wind turbine of any design is 59.3 percent of the total energy or 16/27ths. This is known as Betz's Law or the Betz Limit. In 1919, Albert Betz published proof of the theorem.
The following criteria define wind power (not energy):
P = ½ × ρ × A × V³
Where:
P = Power in Watts
ρ (rho) = Air density in kg/m³
A = Swept area of the rotor in m²
V = Wind speed in m/s

if you cross a true-breeding purple flower with a true-breeding white flower, how many of the offspring will have purple flowers? (purple is dominant to white)
Mendel observed that the F1 generation produced by hybridizing true-breeding (P generation) plants only exhibited one trait of a characteristic. For instance, hybrid plants with purple flowers are always produced when a true-breeding purple flower is crossed with a true-breeding white flower.
Although some interspecific hybrids are fertile and true breeding, some are not. The process of hybridization, sometimes referred to as line- or strain-crossing, is the mating of genetically distinct individuals or groups. It can also involve hybridizing individuals from other species. organisms that reproduce exclusively through self-fertilization, called true-breeding variants. He discovered a purple-flower variety, for instance, that, when self-fertilized, invariably produced offspring plants with all purple flowers. Hybrids: the progeny of two distinct true-breeding species. Two parental lines that are homozygous yet as genetically distinct as feasible are crossed to produce hybrid seeds. Higher yields occur as a result of the heterosis effect, which makes the ensuing heterozygous offspring ("hybrids") significantly more productive than both parents.

Answer:
In the past, changes in solar activity had a significant effect on global climate. When the sun was more active, it would produce more radiation and ultraviolet radiation, which would lead to an increase in global temperatures. On the other hand, when the sun was less active, less radiation was produced, which would lead to a decrease in global temperatures. These changes in solar activity could cause significant shifts in global climate, such as the Little Ice Age, which occurred from the mid-17th century to the mid-19th century.

The number of protons, electrons, and neutrons is 36, 36, and 48 respectively is the element's atomic notation of krypton.
What are protons?Krypton's atomic number is 36. This tells us that an atom of krypton has 36 protons in its nucleus. The number of electrons is equal numbers of protons and electrons. The Number of neutrons is total number of particles in an atom's nucleus, equation becomes mass number (84) = (number of protons(36)) + (number of neutrons(48)).Protons are particles that make up atoms that are positively charged and have a mass as large as that of hydrogen, which is 1.67262 x 10^-27 kg or 1,836 times heavier than electrons. Protons are so deep in the atomic nucleus that they cannot be disturbed by particles outside the atom. This causes the proton to be a stable sub-particle of the atom.Meanwhile, electrons are atomic sub-particles that have a negative electrical charge and are the lightest among other sub-particles.
