Explanation:

Answer:

D, Mastodon tissues contained protein sequences similar to those of modern-day elephants.

Explanation:

19) Cell 1 demonstrate passive transport. 20) Because molecules moved from the higher-concentration side (intracellular space - 180mg) to the lower-concentration side (extracellular space - 20mg). 21) Cell 2 demonstrate active transport. 22) Because molecules moved from the lower-concentration side (intracellular space - 50mg) to the higher-concentration side (intracellular space - 60mg). 23) The student could test ATP

Active and passive transport are the two ways in which molecules can be transported from one side to the other of the membrane.

Passive transport occurs in favor of the electrochemical gradient, meaning that molecules move from the high-concentration side to the low-concentration side. This transport does not need energy to occur.

There are two types of passive transport,

Active transport occurs against the electrochemical gradient, so it needs energy to happen. It carries molecules from a low-concentration side to a high-concentration side. Carrier proteins are involved in active transport.

There are two types of active transport:

In the exposed example,

Cell 1

                     Intracellular concentration     Extracellular concentration

Before                                    180 mg                                 20 mg

After                                       100 mg                               100 mg                        

Before transport, the concentration was higher inside the cell than outside. After, the concentration is lower inside the cell than before and higher outside the cell than before. This fact means molecules moved from the cell interior forward to the exterior. The motion was from the more concentrated side to the less concentrated side and stopped when concentration was equal on both sides of the membrane. This is passive transport.

Cell 2

                     Intracellular concentration     Extracellular concentration

Before                                    50 mg                                 60 mg

After                                       20 mg                                  90 mg                      

Before transport, the concentration was higher outside the cell (60 mg) than inside (50mg). After, the concentration is even lower inside (20mg) the cell than before (50 mg) and even higher outside the cell (90 mg) than before (60mg).

This fact means molecules moved from the cell interior forward to the exterior. The motion was from the less concentrated side to the high concentrated side. This is active transport.

19) Cell 1 demonstrate passive transport

20) Because molecules moved from the higher-concentration side (intracellular space - 180mg) to the lower-concentration side (extracellular space - 20mg)      

21) Cell 2 demonstrate active transport

22) Because molecules moved from the lower-concentration side (intracellular space - 50mg) to the higher-concentration side (intracellular space - 60mg)

The spermaceti is a unique organ found in the head of sperm whales, which plays a crucial role in their physiology and behavior.

Primarily, it functions as an echolocation aid, enhancing the whale's ability to navigate and locate prey in the deep ocean. The spermaceti consists of a waxy, oil-like substance called spermaceti oil, which has the ability to change its state from liquid to solid depending on the surrounding temperature. This property enables the sperm whale to adjust its buoyancy, making it easier to dive deep and resurface without expending too much energy.

Additionally, the spermaceti organ acts as a sound resonating chamber, amplifying the clicks produced by the sperm whale during echolocation. This amplification allows the whale to detect and interpret sound waves reflecting off objects in the water, thereby improving its ability to hunt and communicate. The large size of the spermaceti organ also provides a protective function, as it absorbs impact from potential collisions or threats. In summary, the spermaceti organ is vital to the sperm whale's survival, as it supports navigation, hunting, buoyancy regulation, and communication.

Answer:

Explanation:

A single bacterial cell typically contains between 2 and 4 nanograms (10-9 grams) of DNA. The correct answer is b.

Approximately a few picograms (10-9 grams) of DNA is present in a single bacterial cell. Bacterial cells are prokaryotic cells that reproduce by asexual reproduction or binary fission. Bacterial cells are among the most complex cells in the world. Bacteria do not have any intracellular organelles or membranes, and their DNA is located in the cytoplasm rather than a nucleus.

DNA content in bacteria ranges from less than 1 femtogram to more than 20 picograms. In a bacterial cell, the DNA concentration is frequently 1000 times greater than in mammalian cells. Since a bacterial cell has a smaller genome than a human cell, this indicates that the DNA is more tightly compressed.

The DNA is twisted into a helical structure and packed into an area called the nucleoid. Despite the fact that bacteria lack a nucleus, their DNA is still arranged in a compact, organized manner. The DNA is wound around histone-like proteins that function as architectural supports, similar to the way human DNA is packaged around histones in the nucleus.

The DNA in bacteria is much more compact than the DNA in human cells, allowing it to fit into a smaller space.

At the end of the manipulation, there are 1 × 10^3 cells in tube 3

The initial tube contains a cell concentration of 1 × 10^6 cells/ml. Therefore, the number of cells in the initial tube is 1 × 10^6 cells/ml.

To calculate the number of cells left in the initial tube, we can determine the number of cells that were removed when 100 µl was taken out. This can be calculated as follows:

Number of cells removed = 1 × 10^6 cells/ml × 100 µl = 1 × 10^6 cells/ml × 1 × 10^-4 L/µl × 100 µl = 100,000 cells.

Regarding the number of cells in tube 3 after the manipulation, we know that the volume of cells in tube 2 is 100 µl, corresponding to 1 × 10^5 cells. When tube 2 is mixed with 900 µl of medium in tube 3, the total volume in tube 3 becomes 1 ml (100 µl + 900 µl).

Hence, the number of cells in tube 3 is calculated as follows:

Number of cells in tube 3 = 1 × 10^5 cells/100 µl × 1 ml/1,000 µl = 1 × 10^3 cells.

Therefore, at the end of the manipulation, there are 1 × 10^3 cells in tube 3.

The resistance to malaria carried by individuals in areas where malaria is widespread is the result of 'the individuals' genetic composition'.

What is Malaria?

Malaria is a mosquito-borne infectious disease caused by a parasite. It is a major global health problem and one of the leading causes of death in many developing countries. Some symptoms of malaria include fever, chills, and flu-like illness. If it is left untreated, malaria can be deadly.

The resistance to malaria that some individuals have is largely due to their genetic composition. Genes play an important role in determining an individual’s ability to resist the harmful effects of the malaria parasite. Individuals with certain genetic mutations are more likely to survive and reproduce in areas where malaria is widespread than those without the same mutations. Additionally, these individuals may develop a natural immunity to the parasite, making them less likely to contract the disease. By passing these genetic traits on to their offspring, these individuals can help to ensure the survival of their genes in the face of malaria.

Explanation:

Nerve cells serve an important function in our bodies to relay information as electrical signals from the periphery to the central nervous system. Nerve cells are also called 'neurons' and can be as long as 3 feet. Nerve cells are composed of tiny branches called dendrons which branch into further even smaller extensions called dendrites. They also have a nucleus surrounded by cytoplasm, a cell membrane and an axon. The axon is a long fibre that is coated or insulated in a fatty sheath made out of a substance called myelin. This insulation is what adapts the neuron to carry electrical impulses from one place in the body to another. Neurons work by responding to a stimulus (a change in the environment) that is detected by receptors. There are three main types of neurons- sensory, relay and motor. Once a stimulus is detected, electrical impulses are first sent along the sensory neuron to the central nervous system (CNS). It is then transferred to a relay neuron (also known as an interneuron) which helps pass the information between the sensory neuron and the CNS. These relay neurons can also then pass the information back to a nerve cell known as a motor neuron. Motor neurons carry the electrical impulse to effectors. Effectors are muscles or glands that produce a response. An example of this process can be shown by how the eye responds to light. Light is the stimulus, detected by light receptors called rods and cones. The amount of light entering the eye is then controlled by the muscles of the iris (the effectors).
