Which species does Lucy belong to ?

Answers

Answer 1

One of the most well-known fossilised human ancestor species is known as "Lucy," thus the nickname.

A "funny bone narrative" could be used to describe Lucy's discovery. Johanson found the first piece of Lucy's skeleton at the area of her ulna closest to the elbow when you bump your ulnar nerve in your elbow, it presses against your humerus and gives you that tingly, "funny bone" feeling. Johanson was able to determine from Lucy's shattered ulna's size and shape that it definitely belonged to a primate and might very well be the fossilised remains of a hominin. When Johanson and Gray carefully searched the earth, they were happy to find a great deal more fossilised bone fragments, including pieces of a skull, mandible, ribs, pelvis, thighs, and feet.

INTRO TO CELL RESPIRATION OVERVIEW POGIL: All cells need energy all the time, and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example, as you sit and read this sentence, you are breathing in oxygen, which is then carried throughout your body by red blood cells. But, some cells grow in environments without oxygen (yeast in wine-making or the bacteria that cause botulism in canned food), and occasionally animal cells must function without sufficient oxygen (as in running sprints). In this activity you will begin to look at the aerobic and anaerobic processes that are used by all organisms to produce ATP. Which statement is NOT true based on this intro

Answers

The products formed as a result of cellular respiration are ATP, water and carbon dioxide.

The cells require energy to perform all their cellular functions. The source of energy for them is ATP which is adenosine triphosphate. The amount of ATP which is produced by a cell depends on its requirement and also on the amount of oxygen that is available.  

Depending on whether a particular organism requires oxygen or not, they can be classified as aerobic and anaerobic. Aerobic organisms are the ones which require oxygen whereas anaerobic organisms do not require oxygen. The reaction for cellular respiration can be represented as:

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP

Paleontologists are still debating about whether modern behavior, language, and art appeared more recently in Europe, about 50,000 years ago or further back, based on findings such as the tools and artifacts found at the Blombos cave. What do you think

Answers

Paleontologists have been debating the origins of modern behavior, language, and art for decades. This debate has recently been reignited by the discovery of tools and artifacts at the Blombos Cave in South Africa.

The artifacts found at Blombos suggest that modern behavior, language, and art appeared in Europe approximately 50,000 years ago. However, some paleontologists argue that these behaviors are likely to have appeared much earlier.

I believe that modern behavior, language, and art were likely present in Europe long before 50,000 years ago. Looking at the archaeological record, it is clear that behavior, language, and art have been evolving since the time of our early ancestor Homo erectus. Furthermore, the tools and artifacts found at Blombos are similar to those found in other parts of the world, suggesting that these behaviors were not isolated to Europe.

In addition to the archaeological evidence, there is also genetic evidence that suggests modern behavior, language, and art existed in Europe before 50,000 years ago. Genetic studies of modern humans suggest that all modern populations share a common ancestor who lived approximately 150,000 years ago. This suggests that modern behaviors, language, and art were likely present in Europe at least 100,000 years ago.

Why are there often so many steps between the original signal event and the cell's response?

Answers

This is because a variety of components must be integrated in order to accurately interpret and respond to the signal in a timely and effective manner.

The first step in this process is for the signal to be received and interpreted by the cell. This involves the binding of the signal molecule to a specific receptor, which triggers a cascade of cellular responses. This involves the activation of certain proteins, which then act as mediators of the signal within the cell and help to direct the response.

Once the signal has been received and interpreted, it must then be transmitted to the target organelle or region of the cell. This is done by a variety of molecules such as hormones, neurotransmitters, and growth factors. These molecules are released from the cell and travel to their target where they bind to specific receptors. This triggers a series of responses in the target organelle or region.

Finally, the cell must respond appropriately to the signal. This involves the activation of specific genes, which then produce proteins that alter the cells physiology and behavior. This is a process of gene expression that is tightly regulated and allows the cell to respond rapidly and accurately to the signal.

c. Fatty acids of less than 12 carbons enter the blood and then the liver via the portal vein.
d. Fatty acids of 16 or more carbons enter the lymphatic system directly and then enter the blood via the aorta.

Answers

The correct answer to the question is b. Fatty acids of less than 12 carbons enter the lymphatic system packaged in chylomicrons.

After absorption, fatty acids are taken up by the lymphatic system and transported in the form of chylomicrons. Chylomicrons are lipoproteins composed of lipids, proteins and other substances, and are the largest form of lipoproteins.

Chylomicrons are mainly composed of triglycerides and cholesterol esters, and are responsible for the transport of fatty acids from the small intestine to the rest of the body. These chylomicrons contain fatty acids of less than 12 carbons, which are then transported throughout the body via the lymphatic system.

Once the fatty acids reach the liver, they are either metabolized or stored as fats. In order to enter the blood, fatty acids of 16 or more carbons must be packaged in lipoproteins, such as very low density lipoproteins (VLDL). These VLDLs are then transported to the liver via the portal vein.

About Cilia

The ciliary apparatus is connected to cell cycle progression and proliferation, and cilia play a vital part in human and animal development and in everyday life.

The length of a single cilium is 1-10 micrometres and width is less than 1 micrometre.

Cilia are broadly divided into two types. They function separately and sometimes together:

'Motile' (or moving) cilia are found in the lungs, respiratory tract and middle ear. These cilia have a rhythmic waving or beating motion. They work, for instance, to keep the airways clear of mucus and dirt, allowing us to breathe easily and without irritation. They also help propel sperm.

Primary cilia appear typically as single appendages microtubules on the apical surface of cells and lack the central pair of microtubules (e.g. in kidney tubules).

In the kidney, for example, cilia bend with urine flow and send a signal to alert the cells that there is a flow of urine.

In the eye, non-motile cilia are found inside the light-sensitive cells (photoreceptors) of the retina. These cilia act like microscopic train-tracks, and allow the transport of vital molecules from one end of the photoreceptor to the other.

Fifty pieces of fabric are subjected to the same kinds of stains (grass, mud, coffee). Then 25 pieces are randomly assigned to be cleaned with detergent A and the remaining 25 pieces are cleaned with detergent B. After being laundered, the pieces of fabric are rated on a scale from 110, with 1 being the least clean to 10 being the most clean. The difference in mean ratings (A B) was determined to be 1.5. Assuming there is no difference in the two detergents, 200 simulated differences in sample mean ratings are displayed in the dotplot.Using the dotplot and the difference in mean ratings from the samples, is there convincing evidence that the one detergent is better than the other?Yes, because a difference in mean rating of 1.5 or more occurred only 23 out of 200 times, meaning the difference is statistically significant and there is convincing evidence that A is more effective than B.Yes, because a difference in mean rating of 1.5 or more occurred only 23 out of 200 times, meaning the difference is statistically significant and there is convincing evidence that B is more effective than A.No, because a difference in mean rating of 1.5 or less occurred 167 out of 200 times, meaning the difference is not statistically significant and there is not convincing evidence that one brand is better than the other.No, because a difference in mean rating of 1.5 or more occurred 23 out of 200 times, meaning the difference is not statistically significant and there is not convincing evidence that one brand is better than the other.answer is D Use the excerpt below to answer the question.I perceived clearly that I was participating in a truly significant historic event in which a consensus had been reached as to the supreme value of . . .
