Explanation:
The heart pumps oxygenated blood to the _____ and deoxygenated blood to the _____. A) body:liver B) body:lungs C) brain:lungs D) lungs:nose Eliminate
Answer:
The Answer is B) body:lungs
Explanation:
The body sends oxygenated blood (blood enriched with oxygen) to the body where oxygen is used and blood becomes deoxygenated. This blood when received in heart is pumped to Lungs where oxygen is taken up by blood through alveoli in our lungs. This way deoxygenated blood gets oxygenated and is pumped to the rest of the body and the cycle repeats.
All other options are wrong as blood can only get oxygenated at lungs through small air chambers called alveoli where oxygenation takes place.

AT 8:00 AM you leave home and walk 0.5 km to a friend's house. At 11:30 AM you return home, then travel by car to the mall, which is 10 km away, and arrive at 11:45 AM. What is the total distance traveled?
Answer:
11km
Explanation:
The total distance travelled is the sum of the distance as follows:
- from home to friend's house
- from friend's house back home
- from home to the mall
According to this question;
* I walked from my house to my friend's place and covered 0.5km
* I walked back from my friend's house home in the same 0.5km
* I drove to the mall from my house and covered a distance of 10km
Hence, the total distance covered is 0.5 + 0.5 + 10
= 11km

structures found in eukaryotic cells but not in a bacterial cells are?
Answer:
Bacterial cells do not have a nucleus. They also lack membrane-bound organelles, such as mitochondria or chloroplasts. The DNA of a bacterial cell is also different from a eukaryotic cell.
Explanation:
Eukaryotic cells are by definition those that have a membrane-bound nucleus, a morphological component that is absent from bacterial and archaeal cells.
What is the difference between eukaryotic and prokaryotic cells?Eukaryotic cells are distinguished by numerous membrane-bound structures in addition to the nucleus, including the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others.
Prokaryotic cells lack membrane-bound structures, whereas eukaryotic cells do, including the nucleus.
The existence of mitochondria and chloroplasts, the cell wall, and the makeup of chromosomal DNA are all examples of differences between the cellular structures of prokaryotes and eukaryotes.
Therefore, prokaryotic cells are the name for bacteria's cells. Eukaryotic cells are cells that are found in mammals, plants, and fungi.

B. CMB is constantly generated by stars.
C. CMB is remnant radiation from the Big Bang.
D. CMB is randomly distributed and of differing temperatures across the universe.
Answer:
if I am correct the answer should be C
The answer to the question Which of the following is an accurate description of cosmic microwave background (CMB) radiation is A: CMB is uniformly distributed and of a uniform temperature across the universe. and C: CMB is remnant radiation from Big Bang
The Big Bang is the scientific explanation of the origins of the universe. The Big Bang occurred some 13.77 million years ago.
At the occurrence of the Big Bang, the universe started to develop and the first few atoms were formed. As the universe was formed at the big bang, cosmic microwave background (CMB) radiation developed.
This cosmic microwave background (CMB) radiation is an electromagnetic radiation. CMB radiation is a faint cosmic background radiation filling space. CMB radiation is a remnant radiation from the Big bang. CMB radiation is uniformly distributed and of a uniform temperature across the universe. This cosmic microwave background radiation was first detected in 1965 by American astronomers Arno Penzias and Robert Wilson. This discovery of the cosmic microwave background radiation was evidence of the Big bang.Thus, the CMB is remnant radiation from Big Bang and CMB is uniformly distributed and of a uniform temperature across the universe.
So, the answer to the question Which of the following is an accurate description of cosmic microwave background (CMB) radiation is A: CMB is uniformly distributed and of a uniform temperature across the universe. and C: CMB is remnant radiation from Big Bang

Animals that have a complete
tube-like gut with two openings
Answer:
All mammals, like dogs, cats, and humans; reptiles, amphibians, fish, birds, and even insects.
Explanation:
All mammals, like dogs, cats, and humans; reptiles, amphibians, fish, birds, and even insects are the animals that have a complete tube-like gut with two openings. A system having a tube with two openings i.e. mouth and an anus is called tubular system. In this tubular system, the animals eat with one opening and the other opening is used for excretion of waste and nitrogenous materials from the body so that's why most of the animals have two openings.

what apparatus should be used to measure the surface area to volume ratio of a potato cylinder? with explanation
Answer: Measuring scale/ruler.
Explanation: As it's a cylinder you would just need to find the diameter and the height. You can then use the formula V = πr²h and TSA = 2πr² + 2πrh.
Put the values in the form "surface area : volume" and you get your desired output.
Those things that help you to do the experiment are called apparatus.
The correct answer to the question is measuring scale/ruler.
The other apparatus we use also and these apparatus are as follows:-
Measuring tapesRulerTrigonometryD
As it's a cylinder you have to measure the diameter and the height after that you can then use the formula as:-
[tex]V = \pi r^2h\\ TSA = 2\pi r^2 + 2\pi rh.[/tex]
After measuring the vales place those values in the formula to get the area and volume.

6 Which of the following statements about shark teeth fossil evidence is not consistent with the scientific theory of evolution? (7 Points) A. Many fossils of Shark teeth have recently been found that are all the same size and color compared to modern sharks. B. Many fossils of Shał teeth have been found that show different sizes and serrations (saw-like edges). These fossil teeth have distinct differences and similarities to modern sharks. C. Many fossils of Shark scales have been found that have features of enlarged scales that resemble a brush. Our modern sharks do not have or need this type of scale to survive. D. A new shark fossil has been found that has characteristics in the size of the teeth and the serrations (saw-like edges) that are in between the older fossils found and the modern shark.
Answer:
A. Many fossils of Shark teeth have recently been found that are all the same size and color compared to modern sharks.
Explanation:
Evolution is the change in characteristics of a species over time and it relies on the process of natural selection.
The theory of evolution states that all species are related and gradually change over time.
Since all options except A show a change in the characteristics of shark teeth in the fossils found in relation to modern sharks, option A is the answer. Since, there is no change in characteristics between the Shark teeth in the fossils and that of modern sharks.
So, option A is the answer.
