If a female fruit fly is heterozygous with the allele for white eyes being recessive and the red eyes being dominant on the X-chromosome. She is crossed with a hemizygous red eyed male, what would be the expected ratio of male and female phenotypes if they were bred together?
Answers
Answer:
100% red eyes because there is 50% AA and 50% Aa.
Explanation:
To find the expected ratio of male and female phenotypes if they were bred together, you need to make a punnett square/table.
Female: A a
"A" is white eyes, which is RARE. "a" is red eyes, which is COMMON.
Male: A A
"A" is red eyes, which is COMMON.
Multiply Aa x AA by a punnett square.
GUIDE:
1. AA is common and does not carry the recessive gene of being white-eyed. 2. aa is rare and carries the recessive gene of being white-eyed.
3. Aa is common as being red-eyed since being red-eyed is dominant, but carries the recessive gene of being white-eyed.

HELPP PLEASEE How and why does vomiting too often, for example for sufferers of bulimia, damage the digestive system? Why are the stomach’s gastric secretions harmful, but the oral secretions are not?
Answers
1. Acid erosion of the teeth: The stomach contains hydrochloric acid, which is used to break down food. When an individual vomits, this acid is brought up from the stomach and into the mouth. Repeated exposure of the teeth to this acid can erode the enamel, leading to dental problems such as sensitivity, discoloration, and even tooth loss.
2. Irritation of the esophagus: The act of vomiting can cause irritation and inflammation of the esophagus, the tube that connects the throat to the stomach. Repeated vomiting can damage the lining of the esophagus, leading to conditions such as esophagitis, ulcers, and bleeding.
3. Disruption of the digestive process: Vomiting can disrupt the normal process of digestion and absorption of nutrients in the body. This can lead to malnutrition, as the body is not able to absorb the necessary nutrients from food.
Regarding the stomach's gastric secretions, they are harmful when they are repeatedly exposed to the esophagus and mouth during vomiting because they contain hydrochloric acid, which is highly corrosive and can damage the tissues in these areas. The oral secretions are not harmful because they do not contain hydrochloric acid and are not as corrosive as the stomach's gastric secretions. However, repeated vomiting can still lead to dental problems due to the repeated exposure of the teeth to these secretions.

The organelle denoted by B is the Golgi apparatus.
Golgi apparatus.Eukaryotic cells have an organelle called the Golgi apparatus, which is crucial for the processing, alteration, and classification of proteins and lipids. It is constructed of a number of stacked cisternae, which are flattened, membrane-bound sacs. Endoplasmic reticulum (ER) proteins and lipids are transferred to the Golgi apparatus, where they are altered by the addition or removal of sugars, phosphates, or other chemical groups. Then, it organizes these molecules into vesicles, which can carry them to a variety of locations inside and outside the cell.

What membrane is rough ER connected to?; Is rough ER connected to smooth ER?; What connects rough ER to Golgi?; What is the connection between rough ER and DNA?
Answers
The rough ER's membranes are connected to the outer nuclear membrane, and its lumen is continuous with the perinuclear space.
The Golgi complex and the rough ER collaborate closely. A structure known as a transition vesicle is created in the ER when a protein is produced there. The Golgi apparatus take up this vesicle or sac after floating through the cytoplasm. The vesicle then travels to the cell membrane, where the chemicals are let go of the cell.
The ER transports proteins to the Golgi apparatus.
Rough ER (RER) participates in several aspects of protein synthesis, folding, quality assurance, and dispatch. Because it is covered in ribosomes, it is known as "rough." Smooth E R (SER) is connected to the synthesis and metabolism of lipids and steroid hormones.

A scientist compares to samples of white powder. One powder was present at the beginning of the experiment. The other Potter was present at the end. She wants to determine whether a chemical reaction has occurred. She finds that neither sample bubbles or dissolves in water. She measures the mass of volume of the solids. Sample one has a volume of 45 cm to the third power And a mass of .5 g. Sample two has a volume of 65 cm to the third and a mass of 1.3 g. What should the scientist conclude?
Answers
Based on the given information, the scientist can conclude that a physical change has occurred rather than a chemical reaction.
The scientist can make this conclusion because the samples did not show any signs of bubbling or dissolving in water, which are common indications of a chemical reaction.
Additionally, the measurement of the mass and volume of the samples shows that there has been a change in both properties. Sample two has a greater volume and mass compared to sample one, indicating that some physical transformation has taken place.

Techniques for absolute dating provide more exact origin dates and temporal ranges, such as a range in years.
What is relative and absolute age dating?While relative dating can help identify whether an artifact, fossil, or stratigraphic layer is older than another, it does not provide specific dates. Absolute dating techniques offer more precise origin dates and time frames, like a range in years.
Absolute dating techniques gauge the age of an object by measuring its physical characteristics. The term "radiocarbon dating" refers to one of the most effective absolute dating techniques for archaeologists. Carbon isotopes, different forms of the element carbon, are measured in order for the system to function.
By contrasting a fossil with related rocks and fossils of known ages, relative dating can estimate the fossil's age. By utilizing radiometric dating to track the isotope decay within the fossil or, more frequently, the rocks it is linked with, absolute dating can pinpoint an object's exact age.
