Are eukaryotes more closely related to bacteria or to archaea? Explain.
Answers
Hello!
The Answer Is: Bacteria and Archaea are comprised exclusively of microorganisms; plants, mammals, and microorganisms such as fungi and protists are contained in the Eukarya. Because of their lack of a nucleus, the Bacteria and Archaea were grouped together and called Prokaryotes, but the Archaea are more closely connected to the Eukaryotes than to the Bacteria. The cell walls of bacteria contain a compound called peptidoglycan, while the cell walls of archaea do not. Archaea and bacteria also vary because the composition of the cell membranes of archaea is peculiar and does not contain the same lipids, or fats, present in other species' cell membranes.Thank you for asking this question!

The shadow zone exists due to the of seismic waves.
O A. reflection
O B. refraction
O C. absorption
OD. deletion
Answers
Answer:
B. refraction
Explanation: hope this helps!
The shadow zone exists due to the effect of seismic waves is the refraction. Thus, the correct option will be B.
What is Refraction?Refraction can be defined as the redirection of a wave as it passes from one medium to another medium. The redirection of the waves in a medium can be caused by the wave's change in speed or by a change in the medium of wave.
Seismic waves are the waves which follow the same law of refraction at the compositional boundaries. If the seismic wave velocity in the rock below a boundary is increasing then, the waves will be refracted in the upward direction and this speed up relative to their original path of movement.
Therefore, the correct option will be B.

Why are invasive species dangerous to the environment?
A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.
Answers
Answer:
C
Explanation:
They threaten the other animals. They can take their food, homes, and they don't have natural predators.
Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.
Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.
Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.
The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,
Thus, biodiversity is threatened due to the invasive species.

Which structure is correctly paired with its function? (1) testis — produces nutrients for the offspring (2) placenta — allows nutrients to diffuse from the mother to the embryo (3) uterus — produces testosterone used in egg production (4) ovary — provides a place for the internal development of the embryo
Answers
Answer:
(2) the placenta allows nutrients to diffuse from the mother to the embryo.
Explanation:
The placenta is a shared organ between the mother and the embryo. It diffuses the necessary nutrients from the mother to the future baby and the residues from this one to the mother, so that she can expel them. The placenta separates the mothers and the embryo blood, but it allows the diffusion of said nutrients and wastes through especial parts of the placenta with thin walls.

c. It contains uracil, which functions in protein synthesis
d. It consists of alternating phosphates groups and deoxyribose molecules
Answers
Answer:
d. It consists of alternating phosphates groups and deoxyribose molecules
Explanation:
The statement above best describes a portion of the molecule that is represented here.
Actually, the molecule represented here is the Deoxyribonucleic acid (DNA). The molecule is composed of two polynucleotide. The DNA carries genetic properties that lead to growth, development, reproduction and functioning of organisms. The phosphate group and deoxyribose molecule are found attached to the DNA. The phosphate group is also found in RNA and in ATP. The deoxyribose is known to be a five-carbon sugar molecule which helps to form the phosphate backbone of DNA molecules.
The given molecule is consists of alternating deoxyribose molecules and phosphates groups.
DNA:
It is the biomolecule that is made up of nucleotide polymers. Nucleotide are made up deoxiribose sugar, phosphate, and nitrogenous bases.
In a DNA strand one nucleotide link with another by the phosphodiester bond in which 3' OH of pentose sugar bond with 5' OH of phosphate.

C. Why do different organisms live in different places?
D. Are an offspring's traits similar to those of its parents?
Answers
Answer:
The correct answer is C. Why do organisms in different places have different traits?
Explanation:
Charles Darwin was a naturalist, biologist, and geologist from England and known for his theory of evolution. According to the theory, he observed different types of species of organisms such as birds, plants and fossils all over the world and found similarities in the characteristics.
He suggested that there were variations in species on the basis of specific geological locations. On the basis of these observations, he proposed that all species of organisms are come from the same ancestor but shows the differences due to the response to the condition of their habitat or location

Why is some amount of air is left inside in your lungs after inhalation
Answers
Answer: Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started. The residual volume (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty: There is always some air left in the lungs after a maximal exhalation.
So your answer will be Residual volume...
Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D
It is left because exhaling will never remove all air from your lungs, if it did your body would shut down due to lack of oxygen to all organs. It distributed the atoms throughout the body.

What is the direct cause of most earthquakes?
O Gravitational pull on bedrock by the moon
O deposition of sediment in lakes and oceans
O movement of bedrock along a fault line
O heat exchange betwęen the crust and the atmosphere
Answers
Answer:
Pretty sure it's C or B? Most likely C.
The direct cause of most earthquakes is the movement of bedrock along a fault line. Earthquakes occur when energy stored in the Earth's crust is released suddenly, causing the ground to shake. Hence option D is correct.
What is an earthquake?An earthquake is a sudden and rapid shaking of the Earth's crust caused by the breaking and shifting of rock beneath the Earth's surface. The Earth's crust is made up of tectonic plates that constantly move and interact with each other.
When these plates move against each other, they create pressure that builds up over time until the rock breaks, causing an earthquake.
This energy is released when two blocks of rock, called tectonic plates, move relative to each other along a fault.
The blocks may become stuck, and as the pressure builds up, they may suddenly slip, releasing energy in the form of seismic waves that cause the ground to shake.
The intensity and magnitude of an earthquake depend on the amount of energy released and the distance from the epicenter.
While other factors such as volcanic activity, landslides, or human activities can also cause earthquakes, movement along a fault line remains the primary cause.
Hence option D is correct.
