How does the amount of water in a glass affect the pitch of the sound it produces?

Rocks expand and contract when they are heated and cooled which cause them to break. Physical weathering is experienced to the crust of earth. The last state of physical weathering is sand. Rocks that have some cracks are undergoing frost wedging.

Weathering is a geographical process of deterioration of rocks and minerals into parts and eventually into dust and sand. Thermal stress, a phenomenon caused by temperature variations, can also contribute to mechanical weathering.

The expansion and contraction of rock is influenced by temperature changes. The rock's structure deteriorates as this occurs repeatedly. Physical weathering and mechanical weathering disintegrates rocks without any chemical changes and  it happens to the earth's crust.

Erosion of rocks eventually results in formation of sand. Frost wedging is a process by which ice erodes the rocks having cracks. It is also called ice wedging.

Explanation:

There are different types of asexual reproduction:

Binary Fission

Budding

Fragmentation

Vegetative Propagation

Sporogenesis

Binary Fission

The term “fission” means “to divide”. During binary fission, the parent cell divides into two cells. The cell division patterns vary in different organisms, i.e., some are directional while others are non-directional. Amoeba and euglena exhibit binary fission.

It is one of the simplest and uncomplicated methods of asexual reproduction. The parent cell divides into two, each daughter cell carrying a nucleus of its own that is genetically identical to the parent. The cytoplasm also divides leading to two equal-sized daughter cells. The process repeats itself and the daughter cells grow and further divide.

Fragmentation

Fragmentation is another mode of asexual reproduction exhibited by organisms such as spirogyra, planaria etc. The parent body divides into several fragments and each fragment develops into a new organism.

Regeneration

Regeneration is the power of growing a new organism from the lost body part. For eg., when a lizard loses its tail, a new tail grows. This is because the specialized cells present in the organism can differentiate and grow into a new individual. Organisms like hydra and planaria exhibit regeneration.

Budding

Budding is the process of producing an individual through the buds that develop on the parent body. Hydra is an organism that reproduces by budding. The bud derives nutrition and shelter from the parent organism and detaches once it is fully grown.

Vegetative Propagation

Asexual reproduction in plants occurs through their vegetative parts such as leaves, roots, stems, and buds. This is called vegetative propagation. For example, potato tubers, runners/stolon, onion bulbs, etc., all reproduce through vegetative propagation.

Spore Formation

Spore formation is another means of asexual reproduction. During unfavourable conditions, the organism develops sac-like structures called sporangium that contain spores. When the conditions are favourable, the sporangium burst opens and spores are released that germinate to give rise to new organisms.

In asexual reproduction, a single cell is divided to produce offspring. Simple cell-by-cell division is not possible in multicellular organisms. Most of the multicellular organisms have a complex body design. They have a higher level of organization like tissues, organs and organ systems. Thus, they need a special mode for reproduction.

Advantages of Asexual Reproduction

Following are the advantages of asexual reproduction:

Mates are not required.

The process of reproduction is rapid.

An enormous number of organisms can be produced in very less time.

Positive genetic influences pass on to successive generations.

It occurs in various environments.

Disadvantages of Asexual Reproduction

The major disadvantages of asexual reproduction are:

Lack of diversity. Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent. All the negative mutations persist for generations.

Since only one organism is involved, the diversity among the organisms is limited.

They are unable to adapt to the changing environment.

A single change in the environment would eliminate the entire species.

Asexual Reproduction Examples

Following are the examples of asexual reproduction:

Bacterium undergoes binary fission in which the cell divides into two along with the nucleus.

Blackworms or mud worms reproduce through fragmentation.

Hydras reproduce through budding.

Organisms such as copperheads undergo parthenogenesis.

Sugarcane can be grown through vegetative propagation.

Answer:

Explanation: The merging of male and female gametes during fertilization and the presence of two parents constitute sexual reproduction. The offspring differ from each other and their parents because they receive a variety of genes from both parents. The benefits of sexual reproduction include the offspring's ability to adapt to new surroundings due to genetic variation, which gives the species a survival advantage.

It is less likely that the disease will impact every person in a group. There is only one parent in asexual reproduction. The children are exact replicas of their parents and one another. Asexual reproduction has several benefits, including When conditions are favourable, the population can grow quickly because only one parent is required.

E. coli and other bacteria reproduce asexually. This has the benefit of enabling them to quickly create large numbers of bacteria. The identical genetic makeup of every microbe is a drawback. Every one of the germs would perish if an antibiotic were applied. There would be no people left. Random mutation is the sole process that can add variation to the population.

The majority of animals, including rabbits, reproduce sexually. Because the alleles that the mother and father each possess are combined in the offspring, sexual reproduction brings variety to the species. The fact that sexual reproduction requires more time than asexual reproduction is a drawback. Before the development of the progeny, a mate must be located and the egg fertilized with sperm. However, the benefits of adding genetic diversity to the species overcome this drawback. Given the diversity in the population, it's possible that not every rabbit would be afflicted if a disease struck the rabbit population. It follows that some people would live and be able to reproduce and have more children.

Answer:

Because when they brought the cows back the Autumn Buttercup began to thrive. They took the cows out of the pasture thinking that the Autumn Buttercup would grow better. They noticed that the Autumn Buttercup was thriving in a field nearby where there were cows grazing.

a.) When the cows ate the grass in the fields, it made the grass shorter that the mice couldn't live there and be safe from their predators.

b.) When the cows walk on the soggy ground it pushes up the soil on the sides of the cow print where the buttercup like to grow and not directly in the soggy soil.

Nature has been developing its habitats for thousands and thousands of years. In time there is a balance where there aren't too many plants and animals, but enough food for each. When there is a change in any habitat and something is taken out or introduces, then it changes the population of different species where it may deplet one type of species and let another type of species overpopulate. It can cause species to extinct. It will take nature hundredsof years to find balance again.

Explanation:I’m always right

The athlete must jog for approximately 1.7479 × 10² minutes to complete a distance of 42.19 km at an average speed of 9.00 mph.

To find the time the athlete must jog, we'll first convert the distance from kilometers to miles, then use the formula:

Time (in hours) = Distance ÷ Speed

1 kilometer is approximately 0.621371 miles.

So, the distance in miles is:

42.19 km × 0.621371 miles/km ≈ 26.21875 miles

Now, we can find the time in hours:

Time (in hours) = 26.21875 miles ÷ 9.00 mph ≈ 2.9131944 hours

To convert hours to minutes, multiply by 60:

Time (in minutes) ≈ 2.9131944 hours × 60 min/hour ≈ 174.79167 minutes

Now, let's round this to two decimal places and express the result in scientific notation:

Time (in minutes) ≈ 174.79 minutes

To write it in the requested form (using scientific notation), we move the decimal point two places to the right:

Time (in minutes) ≈ 1.7479 × 10 minutes

So, the athlete must jog for approximately 1.7479 × 10² minutes to complete a distance of 42.19 km at an average speed of 9.00 mph.
