A probe uniquely hybridizes to a specific target gene due to the principle of complementary base pairing, meaning it only binds to the gene with the exact complementary sequence.

A DNA probe will hybridize to a target gene but not to any unrelated genes because each probe is uniquely matched to a specific target gene sequence. This process takes advantage of the principle of complementary base pairing, where adenine pairs with thymine and cytosine pairs with guanine in DNA sequences. Hence, the probe, which is a short synthetic DNA sequence, will only bind with, or 'hybridize' to, the target gene that has the complementary sequence. For instance, if the probe sequence is AATGC, it will bind to the gene sequence TTACG but not to any unrelated genes with different sequences.

Answer:

Rocks can be a physical evidence that shows the earth has changed naturally because most rocks survive for millions of years and you can use this to determine the processes that happened over time.

Explanation:

Answer: Option B

Explanation:

The normal cells when grown in a nutrient medium starts growing in into the petri dish. The cells keep on growing and when the bottom layer of the plate is filled with the cells then the cells in the petri dish stops growing. This is because the cells observes the contact of one cell with another.

This is known as contact inhibition which does not allows the growth of one cell upon another. Contact inhibition is a part of cell signaling in which there are check points that allows the optimum growth of the cells.

This is a mechanism which helps the cells in optimum growth. This helps in preventing the cell from developing tumor by dividing uninterruptedly.

Option B) Normal cells stop growing in a Petri dish once they cover the bottom due to contact inhibition, where cell-to-cell contact signals them to stop dividing to prevent overgrowth.

Normal cells grown in a Petri dish tend to stop growing after they have covered the bottom of the dish because of a phenomenon known as contact inhibition. Once the cells touch each other, they receive signals to stop dividing. This is a regulatory mechanism that prevents the cells from becoming too dense which could lead to resources depletion and provide a defense mechanism against the potential development of cancerous cells.

It contrasts with cancer cells, which lack contact inhibition and continue to grow and divide, forming multilayered cell clusters.

Therefore. the correct answer is option B) contact with other cells stops cell growth.

To understand the environment of the fossilized organism to see what it would have ate or drank anything. in the surrounding area.

Answer:

Explanation:

Understanding the environment or habitat of organisms before fossilization helps us to understand more about them and gives us insight to how they would have interacted with their environment and other organisms.

Of the following given choices;

I.All cells arise from other cells.

II. All living cells require water for survival.

III. All living things are only composed of cells

The answer is; II and III

While these are also characteristics of cells, cell theory, a historic (17th century)theory, was used proved that cells emanated from other cells. The theory is accredited to Matthias Schleiden and Theodor Schwann. It was a major disapproval from the previously popular theory of spontaneous generation.

The other tenets of this theory include;

All living organisms are composed of one or more cells.

The cell is the basic unit of structure and organization in organisms.

The answer is cohesion. Adhesion is when molecules of different substances (an example dew on a leaf) are attracted to each other. And surface tension is a force that creates sort of a thin layer on top of water, so that some small things are able to stand on water. That is how water striders are able to do what they were named after, stride on water.

Final answer:

Membrane fluidity refers to the lateral movement and flexibility of proteins and lipids within the cell membrane, essential for transport, signaling, and maintaining homeostasis. The fluid mosaic model illustrates this, while factors like lipid unsaturation and temperature can affect fluidity.

Explanation:

In biological terms, membrane fluidity refers to the flexibility of the cell membrane, which is an essential property for maintaining cellular function and integrity. The fluid characteristic of a cell membrane is attributed to the fluid mosaic model where integral proteins and lipids are not rigidly fixed in place, but rather float and move laterally within the membrane, much like buoys in water. This fluid nature allows for the components of the membrane to change position and adapt to various conditions, which is critical for processes like transport of substances in and out of the cell, signaling, and interacting with external environments to maintain homeostasis.

Cell membranes are not infinitely flexible, as they can burst if overly stretched or penetrated by a foreign object. However, the ability of the membrane to self-seal after being penetrated by a fine needle demonstrates its remarkable fluidity. Furthermore, membrane fluidity is affected by factors such as the degree of unsaturation in the hydrocarbon tails of the lipids and environmental temperature, both of which can alter the fluid nature of the membrane to ensure proper physiological functioning.

Answer:

The correct answer is it has high specific heat capacity.

Explanation:

The amount of heat energy required in joules to raise the temperature by 1 kelvin of a  1 gm substance is called the specific heat capacity. So substance which have high specific heat capacity requires more heat energy to raise their temperature.

Water has very high specific heat capacity due to having lots of hydrogen bonds that are used to make H₂O molecule. So most of the heat energy is used in breaking the hydrogen bonds between the water molecule which restrict the wide change in the temperature of the water bodies.

So high specific heat capacity means more ability to restrict the change in the temperature. Therefore the correct answer is water has high heat capacity.

These animals are characterized by their fivefold symmetry, although crinoids can have many more than five arms. Additionally, like their echinoderm relatives, crinoids use a water vascular system for feeding and movement. Crinoids have a complex structure that includes a flower-like crown and a stem with ring-like elements; despite their plant-like appearance, they are suspension feeders with tube feet used to move captured food towards the mouth.

Final answer:

When a gas moves from a smaller to a larger container, the particles spread out to occupy the new volume, causing fewer collisions per unit area and, thus, a reduction in pressure according to Avogadro's law. Gas expansion is associated with an increase in entropy and is spontaneous.

Explanation:

When a gas is transferred from a small container into a much larger container, the particles of the gas will spread out more and occupy the new volume available to them. These particles are in constant motion and will continue to move in straight lines until they collide with the walls of the container or with other particles. Due to the increased volume in the larger container, the particles will experience fewer collisions with the walls per unit area, which results in a decrease in pressure, assuming temperature remains constant.

This phenomenon is in line with Avogadro's law, which states that at constant temperature and pressure, the volume of a gas is directly proportional to the number of molecules it contains. When the volume increases, the density of gas particles decreases, and thus the number of collisions against the container walls per unit area will be reduced. This behavior illustrates the properties of gases: they expand to fill the available space, have no fixed shape, and their molecules are spaced widely apart with negligible intermolecular interactions in ideal conditions.

Moreover, the process of a gas expanding into a greater volume is associated with an increase in entropy, as it allows the gas particles more freedom to occupy the space and increases the number of microstates available to the system, which makes it a spontaneous process.

The sun's rays are more concentrated near the equator

Answer:

The answer to the question: Tropical and polar climate zones are very distinct, this is because: the sun´s rays are more concentrated towards the equator than the poles and second, because the ozone layer tends to thin out towards the poles, a system that allows heat to exit Earth to prevent it from overheating the planet.

Explanation:

The first reason why the Tropics tend to be different in their climate from the poles has to do with the way the sun hits different parts of Earth. In the case of the equator, the sun´s rays hit this zone almost directly, which ensures more warmth. But the poles receive these rays more obliquely. But another reason comes from the ozone layers which protect the planet from the sun. In the equator region, which is were the tropic climate is, the layers are thicker and thus trap heat from the sun better, whereas in the poles, these layers thin out. It is almost like the Earth´s own refrigeration system to prevent from overheating.

2 hours and 42 minutes is 2.7 hours.

You multiply 2.7 x 80, getting 216, so the train traveled

216 miles.

To find the distance a train travels given its speed and time, you use the formula distance = speed x time. The speed here is 80mph and the time, when converted entirely to hours, is 2.7 hours. Therefore the total distance the train travels is 216 miles.

In this question, we are asked to find the distance a train travels in a given time. In mathematics, we can determine this by using the formula for distance which is speed multiplied by time. The speed of the train is given as 80mph. The time is given as 2 hours and 42 minutes. But, as the speed is in mph, we should convert those 42 minutes to hours. 42 minutes is 0.7 hours when converted (since 42/60 = 0.7). So the total time then becomes 2.7 hours (2 hours + 0.7 hours).

Now we can calculate the distance. Distance = Speed x Time,  so Distance = 80mph x 2.7h = 216miles.

So, the train travels 216 miles in 2 hours and 42 minutes.

"For years, the polar bear has been the symbol of the global warming movement. But today, the American pika has good grounds to compete with the polar bear for this unwanted honor.

American pikas are suffering because global warming has brought higher temperatures to their western mountain homes.

Pikas live in high mountain ecosystems that are cool and moist. Higher temperatures can cause the pikas to overheat.

Unlike other mountain species that can move to higher altitudes in warming climates, pikas live so high on the mountain that there is no where for them to go. Without our protection and help, American pikas could be the first species with the distinction of going extinct due to global warming. We can't let this happen!

Description

American pikas are small, rodent-like mammals. Although they look like a squirrel or guinea pig, they're actually more closely related to rabbits and hares. Pikas have short, stout bodies with big, round ears. They do not have a visible tail.

Pikas have brown and black fur. The fur is colored to camouflage with rocks. Pika fur is thick to keep them warm in the winter. During the summer, they put on a much lighter coat of fur--however, the fur is still thick enough that a pika might overheat if exposed to very high heat for long periods of time.

Size: Pikas are about 7-8 inches long.

Diet: Pikas are herbivores. They especially love grasses, weeds and tall wildflowers that grow in their rocky, high mountain habitat.

Pikas like to be prepared! In the winter months, there are a lot less grasses and flowers growing in the mountains. To prepare for the lean times, pikas like to save up food during the summer. A pika will collect a pile of extra wildflowers and grasses and lay them out in the sun. The sun's heat dries the plants so they do not get moldy. The plants are stored in the pika's den until winter.

Typical Lifespan: American pikas can live around 6-7 years. Many die after 3 or 4 years.

Habitat

American pikas are found in alpine terrain, above the tree line, on mountains. They live on rock faces, talus and cliffs near mountain meadows. Talus is a rocky area on the side of cliffs, slopes or hillsides.

Range: American pikas live on high-elevation cool mountains west of the Rocky Mountains. They can be found in Montana, Wyoming, Colorado, Idaho, Washington, Oregon, California, Nevada, Utah and New Mexico.

How Pikas Communicate

American pikas are often heard before they are seen. They make calls and sing to define and protect their territory, alert others to the presence of dangers and attract mates. The call sounds like the bleat of lamb, but more high-pitched and squeaky.

Life History and Reproduction

American pikas have adapted to living in very inhospitable environments. They live where most other mammals do not venture to go--the treeless slopes of mountains. It is very cold, rocky and treacherous for the tiny pika.

Pikas help protect themselves by living in colonies. They live near other pikas and will alert the group to predators by sending out a warning call. Weasels, hawks and coyotes can prey on pikas.

Although pikas live in colonies, they are very territorial over their den and surrounding area. They will give off territorial calls to define the boundaries between each pika neighbor. They make their dens among rocks.

Pikas are active in the daytime and they do not hibernate in winter. They are active throughout the year, but they tend to spend most of their time inside the den in the winter. Pikas eat stored grasses to survive and venture out to forage when the weather permits.

In early to mid-spring, American pikas begin to breed. Many pikas breed twice--once in spring and summer. The female is pregnant for a month before giving birth to a litter of 2-6 young. When born, the young cannot function on their own and they depend on their mother for care. It takes about a month for the young to be weaned and 3 months to reach an adult size. After a year, the young develop into breeding adult pikas.

The habitats of pikas, a small mammal, are limited by various factors like temperature sensitivity, available resources, and environmental conditions. They undergo a concept known as 'range shifts', moving habitats due to changing climate. Their survival can be influenced by the availability of resources, similar to certain butterflies and European bird species.

Pikas, small mammals, are influenced by various environmental and survival factors which limit their habitats. These factors include their sensitivity to heat - small animals like pikas lose heat faster than larger ones, influencing their preference for cooler habitats such as mountains. Additionally, pikas are dependent on specific ecosystem conditions and available resources; a concept known in ecology as range shifts, explained by movement of species habitats due to factors like climate change.

For example, similar to certain European bird species and butterflies like the Karner blue butterfly, pikas might shift their range due to environmental changes. Changes in available resources affect pikas as well, as seen in how the distribution of wild lupines influences the Karner blue butterfly population in oak-pine barren habitats.
