Answer:
Conjoined twins are two babies who are born physically connected to each other. Conjoined twins develop when an early embryo only partially separates to form two individuals. Although two fetuses will develop from this embryo, they will remain physically connected — most often at the chest, abdomen or pelvis.

A new mammal has been discovered in the thickly-forested mountains of Papua New Guinea. The squirrel-like animal lives in the canopy of the forest and has a diet rich in leaves. On occasion, however, the animal drops to the ground to quickly fill its cheeks with its own fecal droppings, for ingestion once it is safely back in the trees. The GI tract of this animal would most likely include ________. a simple stomach and a large cecum a simple stomach, a short small intestine and colon, and a small cecum a four-chambered stomach and long intestines a long small intestine with abundant villi and an appendix at the beginning of the large intestine a short intestine and no cecum
Answer:
a simple stomach and a large cecum
Explanation:
Some small animals whose diet is prominent in vegetable matter, have an elongated cecum.
This segment of the digestive tract might be considered the first portion of the large intestine. It receives undigested material, and through the action of bacterial flora, is able to ferment this material and mix its contents with mucous substances to facilitate absorption. Through the walls, the organ can absorb fluids, salts, and nutrients.
The cecum size varies according to the animals. In small organisms, such as the new squirrel-like herbivore animal from the example, the cecum is enlarged. An elongated surface is useful for better digestion and absorption.
Human blood type is an example of which two types of genetics?
A. Multiple alleles and Polygenic inheritance
B. Codominance and Incomplete dominance
C. Incomplete dominance and Polygenic inheritance
D. Codominance and Multiple alleles
The Human blood type is determined by the presence or absence of specific antigens on the surface of red blood cells polygenic inheritance involves the contribution of multiple genes to a single trait, which is not the case for human blood type determination. D
The genetics of blood types involves both codominance and multiple alleles.
Codominance refers to a situation where both alleles of a gene are expressed simultaneously and equally in the phenotype.
In the case of blood type, there are three alleles involved: A, B, and O.
Alleles A and B are codominant, meaning that if an individual inherits both A and B alleles, both antigens will be present on their red blood cells. This results in blood type AB.
Multiple alleles refer to the existence of more than two alternative forms of a gene in a population.
In the case of blood type, individuals can have blood type A (AA or AO genotype), blood type B (BB or BO genotype), blood type AB (AB genotype), or blood type O (OO genotype).
The A and B alleles are dominant over the O allele, which is recessive.
Therefore, the combination of codominance and multiple alleles explains the inheritance patterns of human blood types.
This system allows for the expression of both A and B antigens (codominance) while accommodating the presence of multiple alleles (A, B, and O) in the population.
It is important to note that blood type inheritance is not an example of incomplete dominance or polygenic inheritance.
Incomplete dominance refers to a situation where neither allele is completely dominant, resulting in an intermediate phenotype.
Therefore, human blood type is an example of both codominance (expressing multiple alleles simultaneously) and multiple alleles (more than two alternative forms of a gene exist within a population).

What is a major role that fungi play in ecosystems
Answer:
Fungi play a crucial role in the balance of ecosystems. They colonize most habitats on earth, preferring dark, moist conditions. They can thrive in seemingly-hostile environments, such as the tundra. However, most members of the Kingdom Fungi grow on the forest floor where the dark and damp environment is rich in decaying debris from plants and animals. In these environments, fungi play a major role as decomposers and recyclers, making it possible for members of the other kingdoms to be supplied with nutrients and to live.

If E is the allele for brown eyes and e is the allele for blue eyes, which of these genotypes will allow the individual yo have the phenotype of blue eyes
Answer:
Since blue eyes are a recessive gene, the genotype will need to be ee.
If E is the allele for brown eyes and e is the allele for blue eyes, the genotype that will allow the individual to have the phenotype of blue eyes is ee.
What is genotype?Genotype is the part of the genetic makeup of an organism that determines a specific characteristic (phenotype) of that organism.
According to this question, E is the allele for brown eyes and e is the allele for blue eyes. This suggests that E is the dominant allele while e is the recessive allele.

In a 1973 essay with the same name, geneticist Theodosius Dobzhansky made famous the idea that nothing in biology makes sense except in the light of evolution. From a careful reading of The Serengeti Rules, one could also argue that nothing in biology makes sense except in the light of regulation. Do you agree or disagree with this claim
I agree with this claim because organisms interact with one another in an ecosystem, thereby regulating population sizes in the community.
The Serengeti Rules is a documentary film based on biologist Sean B. Carroll's book (2017). This book explains the balanced functioning of an ecosystem by exploring the discoveries of five pioneering scientists: Mary Power, Bob Paine, Tony Sinclair, John Terborgh, and Jim Estes.
The term 'Serengeti rules' is due to many of these rules were obtained by studying natural populations in the Serengeti National Park (Tanzania).
These rules are a set of simple ecological rules of nature that indicate how ecosystems work.
The Serengeti rules explain how organisms interact with one another in the ecosystem, thereby regulating population sizes in the community.
Some key concepts of the Serengeti rules are as follow: Keynote species is a type of species whose activities govern the wellbeing of other species in the ecosystem. A trophic cascade is a phenomenon by which species impact other species even when they do not directly interact with each other. Downgrading refers to cascading effect of the removal of a species at the top of a food web (e.g., predators)

Cells dispose of large waste molecules through a process called exocytosis.
Exocytosis is the process through which cells can eliminate wastes, which might be useless or toxic, to the extracellular space.
-------------------------------
The endocytosis and exocytosis process refers to molecules transport mediated by vesicles.
Exocytosis occurs from and into the cell and needs energy to happen because it is active transport.Exocytosis involves vesicles or vacuoles. Vesicles or vacuoles can carry substances destined for exportation or cellular wastes. Wastes may be large molecules that result useless for the cells or that might be toxic. During the exocytosis process1) excretion compounds of varying nature accumulate within the
vesicle
2) The vesicle migrates toward the cellular surface.
3) Once in the surface, the vesicle's membrane fuses with the cellular
membrane, and its content is expelled from the cell to the
extracellular space.
4) Vesicle membrane remains fused to the cell membrane until it is
reused during endocytosis events.

1. In a parent pea plant with the allele pair Gg, what is the probability that one gamete will contain the G allele? Why?
2. In a parent pea plant with the allele pair GG, what is the probability that one gamete will contain the g allele? Why?
3. In a parent pea plant with the allele pair gg, what is the probability that one gamete will contain the g allele? Why?
Answer:
If the gamete will get either G or g, the probability will be 1/2 of getting G.
Explanation:
all question 3 answer is that. Because all 3 of question are same. only repeated three times
In a parent pea plant with the allele pair Gg, the probability that one gamete will contain the G allele is 0.5. This is because there are two possible outcomes in which one must definitely fall. So, it is 1/2.
What is Allele?Alleles may be characterized as the alternative form or versions of a gene that are responsible for particular traits in living organisms. They carry a code of genetic sequences within generations.
In a parent pea plant with the allele pair GG, the probability that the gamete will contain the g allele is zero. This is because there is no presence of allele g that can be determined within any gametes. So, it is not possible to get g in the pair allele of GG.
In a parent pea plant with the allele pair gg, the probability that one gamete will contain the g allele is 1 or 100%. This is because both carry g alleles. So, the probability is 100%.
