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.

Answers

Answer 1

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.

Answer 2
Wrong answersGirls get most of their traits from their moms; boys get most of their traits from their dads.

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.

What adaptation do seeds dispersed through ballistochory have?
a)

sail-like structure

b)

smooth and aerodynamic

c)

hollow on the inside

d)

pleasant smell and taste

Answers

Answer:

smooth and aerodynamic

Explanation:

Seeds are usually smooth, like a baseball, so that they cut smoothly through the air and don't have a lot of wind resistance.

The adaptation that seeds dispersed through ballistochory has smooth and aerodynamic. The correct option is b.

What are adaptations?

Adaptation is a biological process that is done by many plants and animals to survive in given conditions. Adaptation is causing the partial or full change in their body or functions to match with the environmental conditions.

Plants with ballistochory means possibly ejects by the seeds full stop this adaptation or evolution happened in which seats are dispersed into many tentacles and seats are dispersed into soils for pollination this comes under wind dispersion.

Seeds launch an angle and release the elastic energy store in the fruit. These adaptations are smooth.

Therefore, the correct option is b. smooth and aerodynamic

Using complete sentences, explain how proximity to major rivers influenced the location of early cities.

Answers

Answer:

Locations along rivers meant faster travel upstream and downstream to rule territories. The city became the place where the ruler or rulers lived together in a stationary spot. The city's location along early rivers encouraged stronger government, which in turn encouraged stronger cities.

Rivers are one of the most crucial resources that played a major role in the development in ancient times. It led to river valley civilization that influenced the location and kingdoms.

What is river valley civilization?

The river valley civilization was one of the most important events that led to the establishment of many kingdoms and regions. The proximity to the river banks influenced many factors.

The cities located on the riverbanks have greater development in services including import, export, travel, agriculture, accessibility, etc. This allowed the people to practice agriculture on a large scale due to the availability of the irrigation system.

The river banks allowed the cities to grow as major trade centers and allowed downstream and upstream travel easier. This also led to the emergence of strong government systems.

Therefore, the proximity to major rivers led to river valley civilization.

eople that have a single allele (gene copy) for sickle cell anemia are typically not sick from the disease and are said to be carriers of sickle cell trait. These people will more often live in the malaria belt of sub-Saharan Africa. The most likely explanation for this is ________. malaria is a cause of sickle cell trait people with sickle cell trait have a better chance of surviving malaria sickle cell trait is passed on to the biting mosquitoes as malaria There is no correlation between a single allele for the pathology and the ability to survive or fight malaria.

Answers

Answer: people with sickle cell trait have a better chance of surviving malaria.

Explanation:

Malaria is a very prevalent disease in the malaria belt of Sub-Saharan Africa which includes much of western and central Africa. The people here have therefore grown to have better immunity to malaria by developing the sickle cell trait.

This has helped them survive both malaria and sickle cell anemia which doesn't affect them even though they carry the sickle cell trait.

Listeriosis is of particular concern for pregnant women because pregnant women are more likely than other population groups to get listeriosis. listeriosis can cause fetal death. Listeria bacteria can cross the placenta and infect the fetus. All of the choices are correct.

Answers

Answer:

The correct answer is ''All of the choices are correct.''

Explanation:

Pregnant women are a risk group for listeriosis, the disease caused by the Listeria monocytogenes bacteria found in contaminated food. This organism can cross the placenta and affect the fetus. Due to the decrease in cellular immunity, pregnant women are part of the population at risk and are 17-20 times more likely to develop listeriosis after the consumption of contaminated food and it usually occurs from the third trimester and appears as a disease mild with not very high fever, joint and muscle pain. Listeriosis can cause miscarriages during the first three months of pregnancy. As the third trimester is reached, the mother is at greater risk. It presents a 40-50% fetal or neonatal mortality. In the first or second trimester it produces septic abortions and intrauterine fetal death, in the third trimester she produces chorioamnionitis and premature labor. In 1/3 cases it can occur asymptomatically in the fetus / neonate. In newborns, listeriosis can cause blood infections and meningitis.
