Is it possible for a punnet square to have a heterozygous dominant / recessive? I have done my research but not able to find it. I think my teacher is tricking me, is it possible? Please help me, thank you!!!!!
Answer:
I'm not sure if I understand what you mean, but based on your question I think the answer is yes.
If the parents are homozygous dominant, and homozygous recessive, it would produce heterozygous dominant and recessive offspring.
If you used both parents as heterozygous, then approximately 50% of the offspring will be heterozygous as well.
I hope this helped!
Also, as a side note, if the offspring is heterozygous, it'll always show the dominant phenotype (unless it's incomplete or codominance)

It is just science not really biology just about continental drift.
Answer:
Q:what happens when a continent moves towards the poles?
A:The climate gradually gets colder and dryer
Explanation:
Researchers studied a typical hardwood forest containing a variety of trees, other plant species, fungi, and animals. The atmospheric carbon dioxide concentrations around the forest were measured in the middle of the day. The carbon dioxide concentration was lowest right next to the forest and steadily increased as the researchers measured farther away from the forest. Explain how this observation supports the Law of Conservation of Mass.
Group of answer choices
The carbon released by animals through cellular respiration is used by the trees to create food necessary for growth and maintenance
The carbon released into the atmosphere by decaying organic matter is increases as you move further away from the forest.
The carbon released by plants through photosynthesis is quickly cycled through the cellular respiration of animals.
The amount of carbon burned by fossil fuels decreases further away from the forest.
Answer:
The carbon released by animals through cellular respiration is used by the trees to create food necessary for growth and maintenance.
Explanation:
Since the trees are using the Carbon to grow they end up absorbing most of it therefore the levels of carbon on the forest are a lot smaller in quantities.
During the process of respiration, carbon is released by animals which is used by the trees in the process of photosynthesis to produce food for itself.
The carbon released by animals through the process of cellular respiration is used by the trees in order to create food that is necessary for growth and maintenance of the plant itself and for other organisms living in that ecosystem.
In this way the plants clean the environment and reduces the concentration of carbondioxide gas in the environment so we can conclude that carbon that is produced by the animals can be used by the other organism for itself supports the law of conservation of mass.

Use the drop-down menus to answer each question about rock formation.
Which type of rock is formed from molten materials?
Which type of rock needs weathering or erosion to form?
The type of rock that is formed from molten materials is known as igneous rock. While the type of rock that needs weathering or erosion to form is known as sedimentary rock.
What is Weathering?Weathering may be defined as a process through which numerous rocks and minerals found on the earth's surface are considerably broken down into smaller fragments. The process of weathering is facilitated by different components like water, wind, ice, etc.
On the other hand, Erosion is different from weathering. This is because erosion deals with the transportation of broken substances or materials through weathering from one place to another with the help of air and water.
It is the gradual destruction and elimination of rock or soil in a particular area. The sedimentary rocks evolved from the activities of erosion and weathering.
Therefore, igneous rocks are formed from molten materials, and sedimentary rocks are formed from weathering or erosion.

A the possible combinations of alleles in offspring
B what an offspring will look like
C the height of offspring
D genetic heritage
Answer:
A
Explanation:
thats literally all u do in a punnet square, then u can analyze the data
A Punnett Square is used in biology to determine the possible combinations of alleles in offspring from a genetic cross. However, it can't predict physical characteristics with certainty, or determine genetic heritage.
Explanation:A Punnett Square is a tool used in biology to predict the probability of specific genotypes and phenotypes in the offspring of a genetic cross. It's used to determine A the possible combinations of alleles in offspring. This means it can show the different ways alleles can combine from both parents to create various genetic traits in their offspring. For example, it could reveal the combinations for a gene related to eye color.
While the Punnett Square does provide possible genetic outcomes, it should be noted that it does not determine what an offspring will look like (B), the height of the offspring (C), or genetic heritage (D). These traits are influenced by both genetics and environmental factors, and while genetics can dictate possible outcomes, it cannot determine them with 100% certainty. Therefore, the Punnett Square focuses primarily on potential genetic combinations of alleles.

what do the effect of catalase on the decomposition of hydrogen peroxide
Catalase is an enzyme that accelerates the breakdown of hydrogen peroxide into water and oxygen in the body. This is a critical process because hydrogen peroxide is harmful to cells. The reaction is expedited by catalase, which acts as a catalyst, without being consumed or changed permanently.
Explanation:Catalase found in cells, particularly in peroxisomes, plays a crucial role in the decomposition of hydrogen peroxide (H₂O₂) into water (H₂O) and oxygen (O₂). This reaction is important because hydrogen peroxide is a potentially harmful byproduct of various metabolic processes in cells, and its buildup can be toxic. In the process, catalase acts as a catalyst, meaning that it speeds up the reaction without being used up or altered permanently. For example, if you put a piece of liver (which contains a lot of catalase) into hydrogen peroxide, you'll notice effervescence or bubbling. This bubbling is oxygen gas being produced from the decomposition of hydrogen peroxide by catalase.

What is a 2-factor cross biology
Answer:
23 +34
Explanation:
because its math
Final answer:
A 2-factor cross in biology involves studying the inheritance pattern of two different traits in offspring. It helps determine whether the traits are inherited independently or if there is any linkage between them.
Explanation:
In biology, a 2-factor cross refers to a breeding experiment involving two factors or traits. This type of cross helps determine the inheritance pattern of two different traits in offspring. For example, if we are studying flower color and plant height in peas, a 2-factor cross would involve examining how these traits are inherited together in the offspring.
One example of a 2-factor cross is the dihybrid cross, which involves studying the inheritance of two different traits at the same time. This type of cross can help determine whether the two traits are inherited independently of each other or if there is any linkage between them.
