Which statement about inheritance is true?
Girls get most of their traits from their moms; boys get most of their traits from their dads.
Male offspring will always have an X-linked genetic disease if the mom is a carrier.
Fathers always determine the gender of the offspring in humans.
Males never have Y chromosomes.
Answer:
The correct answer is the third statement.
Explanation:
In humans, the males possess one X and one Y chromosome, while the females possess two X chromosomes. Thus, the female always donates X chromosome to the gamete. In any case, the female always generates a similar kind of gamete. While the male either pass X or the Y chromosome to the progeny.
When the gamete with the X chromosome combines with the female gamete than the offspring would possess XX chromosomes and will be a female. On the other hand, when the gamete comprising the Y chromosome combines with the female gamete than the offspring would possess the XY chromosome and will be a male. Thus, it is the father who determines the gender of the offspring.
This is wrong. Parents gender does not affect traits passed on.
Males never have Y chromosomes.This is wrong, Males have to have a Y chromosome. (XY)
Male offspring will always have an X-linked genetic disease if the mom is a carrier.This is wrong. The male offspring have a 50/50 chance if the mother is a carrier, if she has the deseace than all the sons will have the decease.
Correct answerFathers always determine the gender of the offspring in humans.This is because the mom is XX and the dad is XY. The mom gives the X in the gene, and the dad gives the X for daughters (X,X) and gives the sons a Y (X,Y) Males are always XY.
If the mom is a carrier, h, then it will get passed down 50% of the time, and when it gets passed down to the males, they wiill have the deseace. If the mom passes the deacease down to the daughters, 50% will be a carrier too if the dad does not have the deseace. If the dad has the deacease, than 50% of the daughters will have the deacease, and the other 50% will be carrier, and still, 50% of the sons will have the deacease, while the other 50% will be completely clean. So in total 25% of the offspring will be a carrier, 50% will have the deacease, and the other 25% will not have the deacease or be a carrier.

A population of rabbits has individuals with fur coloring that ranges from white to brown. The population lives in a temperate deciduous forest where the summers are mild and average about 50°F. The winters are often below freezing.
If warmer temperatures last longer into the fall and the average temperature in the winter is getting warmer, what do you expect to happen to the population?
The percentage of the population with brown fur will decrease.
The percentage of the population with white fur will decrease.
The population will increase in size, but the color percentages will remain unchanged.
The population will decrease in size, but the color percentages will remain unchanged.
Answer:
The best option for this problem would be the second option: "The percentage of the population with white fur will decrease"
Explanation:
Think about animals up in the north. Most of them are white because it helps them blend in the snow. And so an increase in average temperatures would mean less snow time. This would mean that the white rabbits will be more vulnerable to attacks for a longer time period of the year compared to previous years with a short time period of being vulnerable.

How are meiosis and mitosis similar?
Answer:
both processes of cell division in which cells reproduce
they share similar steps (prophase, metaphase, anaphase, telephase, cytokinesis) (meiosis has a second division but still follows the same steps)
Answer:
Meiosis II is very similar to mitosis; chromatids are separated into separate nuclei. As in mitosis, it is spindle fibers that “pull” the chromosomes and chromatids apart. The end result of meiosis is four cells, each with one complete set of chromosomes instead of two sets of chromosomes.
Explanation:
Hope this helps

Answer:
Following are the difference to the given question:
Explanation:
Plant cells have a wall of a cell, while cells of animals wouldn't. Cell membranes offer plants support and shape.Chloroplasts in plant cells do not occur, however, in animal cells. Chloroplasts allow plants can grow things via photosynthesizing.Plant cells typically get a vacuole(s) that is one or even more big, whereas animal cells are vacuous, whether any.Large vesicles assist shape the plant and enable food and water to be store for future use.In animal cells, the storing function takes a smaller part and the vacuoles, therefore, are smaller.A plant cell is square in its structural way and an animal cell is often spherical and irregular.The cell of a plant has a vesicle in its big form which is significantly smaller than the plant cell, as well as the animal cell was the or more vacuoles. In general, a vacuole is a storage area for the cells to store water.There is no chloroplast inside the animal cell. Chloroplast is a plant cell that produces photosynthesis from its food. The plants have a green color.The nucleus is located throughout the cell of the plant on the other edge of the peripheral cytoplasm, while the nucleus is in the animal's core.Plant cells store food of starch while animal cells store food of glucose.The mitochondria in the plant are fewer and also have tube cristae, whereas the animal cells have grown in various.What does alteration of generation mean?

Which of the following statements describes the conditions of a pneumothorax? View Available Hint(s) Which of the following statements describes the conditions of a pneumothorax? The intrapulmonary pressure equalizes to atmospheric pressure. Both lungs partially or completely collapse. The intrapleural pressure decreases. The presence of air in the pleural cavity.
Answer:
The presence of air in the pleural cavity
Explanation:
A pneumothorax occurs when air builds up between the lung and the chest wall. In consequence, pneumothorax occurs when air gets into the pleural cavity (i.e., the space between the lung and the chest wall) and causes a fully and/or partially collapsed lung. Some of the most common symptoms of pneumothorax include shortness of breath (respiratory distress), rapid breathing, rapid heart rate, fatigue, agitation, dry cough, etc. Pneumothorax can be caused by a chest injury, an accident during a medical procedure, damage from underlying lung diseases, etc.

How is an ectotherm most likely to maintain homeostasis during hot weather?
Answer:
The correct answer is - by burrying underground.
Explanation:
In the ecthermal animals who are also known as the cold-blooded animals. These animals change the heat from the environment and exchange through various ways if the weather is too hot.
Evaporating by tounge, moving to a shady area like under a tree or rocks, burrying the ground for the cooling down their body are few of the ways they maintain their homeostasis during hot weather.
