2.True
3.false
Explanation:
5. You cross one black (Bb) mouse with one brown (bb) mouse. Complete the Punnett square to find the expected ratio of black to brown mice pups. All six mice pups in the litter have brown fur. Explain this result.
I think all the mice had brown fur due to epistasis
Explanation:
The expected results would be 50% black and 50% brown and the ratio could be 2:2. But, if epistasis occurred and the brown fur gene overshadowed the black fur gene, then all the offspring could have brown fur.
The Punnett square to find the expected ratio of black to brown mice pups is to be considered when all the mice had brown fur because to epistasis.
Completion of the Punnett square:The expected result should be 50% black and 50% brown and the ratio should be considered as the 2:2.
In the case when epistasis should be arisen and brown fur gene should be overshadowed the black.
Hence, the same should be considered.

Contrast the terms “parasitism” and “mutualism” in a sentence
Answer:
Explanation:
Mutualism is the interaction between two or more organisms where both organisms can benefit from the interaction while Parasitism is the interaction between two species where only one benefits from the other organism and the other is harmed in return
Answer:
When both the partners or organisms get benefits from one another by living together is known mutualism. When only one partner or organism gets benefits without any effect on the other is commensalism. When one partner or organism gets benefits while the other is harmed is known as parasitism.

Explanation:
Show are meiosis and mitosis different
Answer:
The purpose of mitosis is the creation of diploid somatic cells and the purpose of meiosis is the creation of haploid sex cells.
Explanation:
Mitosis takes place in somatic, or body cells, and meiosis takes place in gametes, or sex cells. The purpose of mitosis is growth and repair, while the purpose of meiosis is creating gametes with half the normal number of chromosomes and is for reproduction. Mitosis goes through Interphase, Prophase, Prometaphase, Metaphase, Anaphase, Telophase, and Cyokinesis once to produce two genetically identical diploid somatic daughter cells. Meiosis goes though that twice (Meiosis I and Meiosis II) to produce 4 genetically unique haploid gametes. It has stages (Prophase, Metaphase, Anaphase, and Telophase) such as Prophase I and Prophase II because meiosis occurs twice. Another difference is that mitosis happens throughout your life and meiosis occurs before females are born and throughout a males life.

Which of the following best describes how much precipitation and evaporation occurs over the ocean?
A) A small amount of the evaporation and precipitation
B) Most of the evaporation and precipitation
C) Most of the evaporation but a small amount of the precipitation
D) A small amount of the evaporation and most of the precipitation
Answer:
C. Evaporation occurs when the ocean water comes up to the clouds and change it from a liquid to a gas, however precipitation occurs just a tinsy bit because precipitation is actually like rain, hail, sleet, etc... so that doesn't happen all the time

the cells produced during meiosis are?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring.

Answer:
Reproduction.
Explanation:
Reproduction is the process by which organisms produce new organisms of the same type. This can be asexual (an organism not needing a mate to reproduce like certain plants or bacteria) or sexual reproduction (needing a mate to reproduce). Most species can only produce sexually.
Which experiment could the scientists use that would best determine if these tiny structures are spores?
Answer:
The experiment that scientists could use that would best determine if the tiny structures are spores is called Opto-Electronic Imaging and Imaging Processing.
Explanation:
Optoelectronics speaks to the body of knowledge and of electronic devices that source, detect and control light and how they are used or applied. It is founded on the quantum mechanical effects of light on electronic materials.
Besides Optoelectronic Imaging, there are several other techniques that can be used to identify spores. Some of them are:
1. The culture-based methods: These methods involve the growing of spores on an agar plate and on the enumeration of colony units formed therein.
2. Culture-independent methods: These methods are based on
the counting of spores under an electron microscope. This method utilizes the hybridization of DNA for the detection of pores. Opto-electric imaging is preferred and considered more efficient because it is faster than all the above processes that have been mentioned. The above processes have the disadvantage of time-consumption.

What is the purpose of mitotic cell division in multicellular organisms (give all 3 purposes)? Compare this to the purpose of mitotic cell division in single celled eukaryotes. Use vocabulary words.
Answer:
The correct answer is - The growth and tissue repair are the major purpose of mitotic cells in multicellular organisms.
Explanation:
The purpose of mitotic cell division in multicellular organisms can be understood by the three points:
1. somatic cells divide through mitotic cell division.
2. Every multicellular organism shows growth and develop with time in size
3. Every cell of the body is repaired with the help of the mitosis that replaces the damaged cell with the new cell.
Single-celled eukaryotes show asexual reproduction by binary fission which is a form of mitosis.

Why did Mendel study pea plants?
Answer:
Pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow and could be bred rapidly and had many several observable characteristics like petal color and pea color. Mendel used a tall plant and a small plant expecting a medium plant to com out. That was not the case one tall plant came out and so did 3 small ones. This is because of genetics. And the genetic chart showing what the percents are.

D. A cladogram
Answer:
A. a phylogenetic tree. it says that i need 20 more characters to enter so this is me wasting them. but the answer is A
The given diagram basically represents a cladogram. The correct option is D.
What is cladogram?A cladogram is a type of diagram that depicts the evolutionary relationships between organisms.
It is a branching diagram in which the nodes represent the descendants' most recent common ancestor. The cladogram is based on the organisms' shared characteristics or traits.
These characteristics, which can be physical or genetic in nature, are used to classify organisms into clades.
Clades are groups of organisms that share a common ancestor, and they are represented on the cladogram as branches.
The organisms are more closely related the closer the branches are to each other. Cladograms are commonly used in biology to study organisms' evolutionary histories.
Thus, the correct option is D.

why is important to use an organism with a recessive phenotype in a cross with an organism of unknown Genotype
Answer:
One of the central conclusions Mendel reached after studying and breeding multiple generations of pea plants was the idea that "[you cannot] draw from the external resemblances [any] conclusions as to [the plants'] internal nature." Today, scientists use the word "phenotype" to refer to what Mendel termed an organism's "external resemblance," and the word "genotype" to refer to what Mendel termed an organism's "internal nature." Thus, to restate Mendel's conclusion in modern terms, an organism's genotype cannot be inferred by simply observing its phenotype. Indeed, Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations. Mendel thus wondered how organisms preserved the "elementen" (or hereditary material) associated with these traits in the intervening generation, when the traits were hidden from view.
It is important to use an organism with a recessive phenotype in a cross with an organism of an unknown genotype to identify the recessive traits.
What are phenotype and genotype?The observable traits of an individual are the result of gene expression; the clinical manifestation of a person with a certain genotype is called the phenotype of an individual. Some examples of the phenotype are height, skin color, eye color, hair nature, etc.
The term "genotype" refers to an organism's whole gene pool, or, in other words, the genetic makeup of that creature. The phrase can also be used to describe the alleles, or different forms of a gene, that an organism carries in a more specific meaning.
A recessive phenotype is used in a cross with an organism of unknown Genotype to identify the recessive traits.
