When placed in tap water, which is a hypotonic environment, animal cells have a higher solute concentration inside of the cell compared to the tap water. ... This, however, is not the case for plant cells which has a strategy to prevent lysis when put in a hypotonic environment. So the answer to your question is D
Solution:
The function and mobility of each joint depends on its anatomical design. Joints that permit no movement or slight movement are common in the axial skeleton where basic structural support and protection is expected. Joints that are freely moveable are common in the appendicular skeleton where mobility is required. Is known as articulation.
The tibial collateral ligament reinforces the medial side of the knee joint and the fibular collateral ligament reinforces the lateral side of the knee joint. Two popliteal ligaments reinforce the posterior side of the knee joint.
Answer: More than 99 percent of all organisms that have ever lived on Earth are extinct. As new species evolve to fit ever changing ecological niches, older species fade away. But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 75 to more than 90 percent of all species on Earth have disappeared in a geological blink of an eye in catastrophes we call mass extinctions.
Though mass extinctions are deadly events, they open up the planet for new forms of life to emerge. The most studied mass extinction, which marked the boundary between the Cretaceous and Paleogene periods about 66 million years ago, killed off the nonavian dinosaurs and made room for mammals and birds to rapidly diversify
<span>The answer is c. Chromosomes carry the codes for hereditary traits. Chromosomes are thread-like structures made of proteins and DNA. Codes for hereditary traits are present in a molecule of DNA. Chromosomes can be found in the nucleus of each cell. Humans have 46 chromosomes in each cell (not 460) arranged in 23 pairs (not 230). Hope this helps. Let me know if you need additional help!</span>
Answer:
i-propyl cyanide
Explanation:
But i-propyl cyanide is the largest and most complex organic molecule found to date - and the only one to share the branched atomic backbone of amino acids. "The idea is to know whether the elements that are necessary for life to occur… can be found in other places in our galaxy."
