A couple is having a baby. They go to the doctor to find out the sex and they see
that the chart has the sex chromosomes as XX. Are they having a boy or a girl?"
answer:
a girl
explanation:
the X and Y chromosomes, also known as the sex chromosomes, determine the biological sex of an individual. females inherit an X chromosome from the father for a XX genotypemales inherit a Y chromosome from the father for a XY genotypemothers only pass on X chromosomesThe right side of the heart collects oxygen-poor blood from the body and pumps it into the lungs, where it releases carbon dioxide and picks up oxygen.

Which of the following is the best example of natural selection?
(1) A cheetah living in a zoo lives 10 years longer than average.
(2) The shell of a crab becomes harder over time as a result of being hunted by a predator.
(3) A person's muscles become firmer from riding a bike for exercise.
(4) A population of a rabbit's decreases in number as some move to another area.
Answer:
A cheetah living in a zoo lives 10 years longer than average.
Explanation:
because Cheetahs living in captivity generally live a great deal longer than those in the wild, the life span of wild cheetahs is about 8 to 10 years, as opposed to 12 to 17 years for those in captivity according to the National Zoological Park, a sure fire sign of a healthy life.
The best example of natural selection is that the shell of a crab becomes harder over time as a result of being hunted by a predator, which is mentioned in Option 2, as the other options are not absolutely correct for it.
What is natural selection?Natural selection is the process where certain traits that are advantageous to an organism's survival and reproduction become more common in a population over time. In option (2), the harder shell of a crab is an adaptation that helps the crab avoid being preyed upon by its predator. As a result, the crabs with harder shells are more likely to survive and reproduce, passing on their advantageous trait to their offspring. Over time, the population of crabs will have a higher proportion of individuals with harder shells, leading to the evolution of this trait in the population.
Hence, the best example of natural selection is that the shell of a crab becomes harder over time as a result of being hunted by a predator, as mentioned in Option 2.

Regarding Natural Selection, what does the term FIT mean?
Answer:
to an evolutionary biologist fitness simply means reproductive success and reflects how well an organism is adapted to its environment.We call them fit because of how successfull they reproduce not how well they do at athletic events
Explanation:
Answer:
The term "fitness" in evolutionary biology means the ability of an organism to pass on its genetic material to its offspring. Biological or "Darwinian" fitness is being able to live long enough to reproduce and keep the population or species alive.
Peppered moths in the early 1800's were mostly white-winged insects. During the Industrial Revolution, these moths had a hard time staying camouflaged against the ash-covered environment near factories. As a result, the moths started producing more offspring that had gray wings. This gradual change in the genetics of the moth is called an?
Answer:
Evolution.
Explanation:
Evolution is the gradual change that occurs in the genetics of an organism. Change in environment of an organisms play an important role in evolution. Evolution leads to the change in the physical structure of an organisms that is compatible to that environment so gradual change occurs in the genetics of the moth having gray wings which helps the moth to hide in the ash.

The greater an object's ____ the stronger the gravitational force on it.
A. mass
B. distance
C. weight
Answer:
The greater an object's mass the stronger the gravitational force on it.
The greater an object's mass, the stronger the gravitational force on it.
What is the force of gravity?The force of gravity depends directly on the mass of the objects and inversely on the distance between them. Therefore, an object with a greater mass will have a stronger gravitational pull on other objects, regardless of their distance apart.
The weight of an object is a measure of the force of gravity on it and is equal to the object's mass multiplied by the acceleration due to gravity. So, while mass and weight are related, they are not the same thing. Mass is a measure of an object's amount of matter, while weight is a measure of the force of gravity acting on an object.

Which statement is true about the nitrogen bases in DNA and RNAI
Answer:
Uracil (U) is found in RNA only. Thymine (T) is found in DNA only.
Explanation:
DNA has the nitrogenous bases adenine (A), thymine (T), guanine (G), and cytosine (C). On the other hand, RNA has the nitrogenous bases adenine (A), uracil (U), guanine (G), and cytosine (C).
Thus, only RNA has uracil (U) and only DNA has thymine (T).

What food item will provide 1 mole of sodium in the least mass? What is that mass?
Answer:
Can of soup.
Explanation:
Can of soup will provide 1 mole of sodium in the least mass because the concentration of sodium in can of soup is higher than other food items. The can of soup has 300 mg of sodium while on the other hand, honey nut, frosted flakes, Oreos and pop Tarts has 190 mg, 150 mg, 80 mg, and 180 mg of sodium respectively which is lower than can of soup so we can say that less amount of soup provides more sodium.
