Yeasts life cycle is categorized as • A. Gamete-Zygote
• B. Diploid-Dominant
• C. Haploid-Dominant
• D. Alterations of Generations
An example of alternations generation is the life cycle of yeast (option D)
As a result of the alternation of generations, plants alternate between two distinct life stages, or generations, throughout their life cycle: the haploid gametophyte stage and the diploid sporophyte stage. The terms haploid and diploid describe how many chromosomes each cell has.
Many other types of organisms, such as fungi, algae, and plants, share the alternation of generations seen in yeast. In this life cycle, organisms pass through two distinct phases—the sexual phase and the asexual phase, each of which is referred to as a generation.
When yeast is added (pitched) to the wort, its life cycle emerges from slumber. The four phases of yeast growth are rather arbitrary because they could all occur at the same time: Lag time, growth phase, fermentation phase, and sedimentation phase are the order in which they occur.

Human abo groups are best described as an example of multiple allelism.
The I gene is in charge of the ABO blood grouping system. There are three allelic variants of this gene: IA, IB, and i. I is the recessive allele, while IA and IB are dominant alleles.
An example of multiple allelism is the ABO blood group, which has three alleles in a population. The I gene is in charge of the ABO blood grouping system. There are three allelic variants of this gene: IA, IB, and i. I is the recessive allele, while IA and IB are dominant alleles. An example of multiple allelism is the ABO blood group, which has three alleles in a population.
According to the ABO blood group system, which is based on the inherited characteristics of red blood cells (erythrocytes) as shown by the presence or absence of the antigens A and B, which are carried on the surface of the red cells, human blood is categorized according to these characteristics. Consequently, people may have type A, type B, type O, or type AB blood. Karl Landsteiner, an immunologist from Austria, originally recognized the A, B, and O blood groups in 1901.
Antibodies against type B red cells are present in the serum (fluid) of blood that contains red cells with type A antigens on their surface. Red blood cells in type B blood will be killed by the antibodies in the recipient's blood if it is transfused into people with type A blood. Similar to how to type B blood's anti-A antibodies will destroy type A red cells. If no other blood group system is present that is incompatible, type O blood can be injected into people with type A, B, or O blood. Type AB blood donors can receive type A, B, or O blood.

Each of the body systems:
a) depends on the others to function
b) performs a single task
c) is interchangeable
d) is controlled by the lungs
Answer:
a) depends on the others to function
Explanation:
The body systems work together to maintain homeostasis and keep the body functioning properly. Each system has specific functions, but they all rely on each other to function properly. For example, the respiratory system is responsible for bringing oxygen to the body, but it depends on the circulatory system to transport the oxygen to the cells. Similarly, the digestive system breaks down food and absorbs nutrients, but it depends on the circulatory system to transport those nutrients to the cells. Therefore, it is not accurate to say that each body system performs a single task or is interchangeable. Additionally, the lungs are a part of the respiratory system, but they do not control all of the body systems.

most neurons lack ________ and so are permanently blocked from undergoing cell division.
Most neurons lack mitotic spindles and so are permanently blocked from undergoing cell division.
Most neurons lack mitotic spindles, which are structures that form during cell division and are responsible for separating the chromosomes into the daughter cells.
The mitotic spindle fibers, which resemble black rope-like filaments, are joined to the duplicated chromosomes during metaphase. The kinetochore, a protein area near the centromere, is where these rope-like structures are attached.
The absence of mitotic spindles in most neurons means that they lack the ability to divide and reproduce, making them permanently blocked from undergoing cell division. This is one of the reasons why the nervous system is not able to repair itself like other tissues in the body.

what happens when energy travels through solids liquids and gasses ? someone please help me
Draw a diagram (develop a model) that shows what happens when warm water mixes with cold water in the ocean. Use your model to explain how this causes ocean currents.
Note that a phenomenon called Convection Circulation occurs when warm water mixes with cold water in the Ocean.
Because warm water is less dense, when warm water and cold water combine, warm water rises to the top, causing a phenomenon called "convection Circulation". During the day, the water at the ocean's surface heats up.
Water has unique qualities, one of which is density, which is connected to convection and density-driven circulation in the ocean. At 4oC, liquid water is densest, not solid ice, which is lighter.
This explains why ice floats while cold, thick liquid water sinks in the ocean. By increasing the density of water, saltwater provides another dimension. Temperature and salinity interact to create an overturning, density-driven circulation in the ocean known as thermohaline circulation. See attached diagram.
