Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Answer:
1. meiosis require two nuclear division but mitosis requires only one nuclear division
2. meiosis produces four daughter divisions, and there are four daughters cell following cytokinesis. Mitosis followed by cytokinesis result in two daughter cells
3. in meiosis, the four daughter cells are haploid and have half the chromosome number as the parent cell. In mitosis, the daughter cell have the same chromosome number as the parent cell
4. in meiosis the daughter are genetically dissimilar to each other and to parent but in mitosis, the daughter cells are genetically identical to each other and to the parent.

Although Arroyo does not mention the term "watershed," it was discussed in the unit as being closely related to and impacted by drought and floods. Please discuss how the watershed relates to drought and heat. How might Arroyo have integrated the term watershed into her talk?
Answer:
Arroyo integrated the term “watershed“ by saying that Oxfam and Swiss Re with the Rockefeller foundation are helping farmers building hillside terraces to conserve water and they are also providing for insurance when the droughts do come.Water shed relates to drought and heat because it will suffer and there would be less water to fill surface water resources and less water to make its way through the earth and into groundwater reservoirs.
About how long ago did our solar system start to form?
O About 5 million years ago
O About 14 million years ago
O About 5 billion years ago
About 14 billion years ago
Answer:
about 5 billion years ago
Explanation:
Our solar system formed about 5 billion years a go from a dense cloud of interstellar gas and dust.
Our solar system started to form approximately 5 billion years ago. Option 3 is correct.
This estimation is based on scientific evidence and observations of the formation and age of celestial bodies in the universe. The formation of our solar system is believed to have been initiated by the gravitational collapse of a giant molecular cloud composed of gas and dust. As the cloud collapsed under its own gravity, it began to spin and flatten into a rotating disk-shaped structure known as the protoplanetary disk. The central region of this disk eventually formed the Sun, while the surrounding material coalesced to form planets, moons, asteroids, and comets.
The age of our solar system is determined through radiometric dating techniques, which involve measuring the ratios of radioactive isotopes in rocks and meteorites. These measurements, combined with other astronomical observations and models, provide a reliable estimate of the age of the solar system. The current scientific consensus is that the solar system formed approximately 4.6 billion years ago, placing its origin in the early stages of the universe's development. This understanding of the solar system's age is crucial for studying its evolution, understanding the formation of planets, and exploring the conditions necessary for the existence of life.

What importance of wilderness areas in an ecosystem?The risk of extinction is reduced by wilderness, with the risk being doubled for species found outside those places.
Additionally, a variety of species can be found in both wilderness and non-wilderness places, and their ability to survive depends heavily on the wilderness's undisturbed habitat.
The advantages of wilderness are many. There is so much more to wilderness than just a place to camp, trek, or fish.
Our water and air are purified by wilderness. It serves as both a habitat for wildlife and a source of income for nearby towns.

If a person did not eat for several days, which sequence of events would occur? Glycogen stores would be depleted first, then structural proteins, and then stored lipids. Lipid stores would be depleted first, then stored glycogen, and then structural proteins. Proteins stores would be depleted first, then stored lipids, and then stored glycogen. Glycogen stores would be depleted first, then stored lipids, and then structural proteins.
Answer:
The correct answer is "Glycogen stores would be depleted first, then stored lipids, and then structural proteins."
Explanation:
When an individual starts starving, the glycogen store is depleted first because that is the storage form of glucose. After depletion of the glycogen, the body then burns fat reserves in the body which are also good sources of calories. After prolonged period of starvation, the body then converts structural proteins (usually in the form of glucogenic amino acids) into fuels for energy.
It should be noted that NOT all the glycogen are used up immediately because the brain cells and the red blood cells prefer energy from glucose and hence the body reserves some glycogen strictly for them.

The Earth's biodiversity is determined by the variety of all living organisms on Earth. In recent years, ecologists and other scientists have encouraged the preservation of global biodiversity through the protection and management of natural ecosystems. Preserving the biodiversity of the Earth is important because
Answer-:
Preserving the biodiversity of Earth is important because biodiversity increases the efficiency of ecosystems where every species, no matter how small, has an important role to play. A greater number of species of plants means a larger range of crops. Greater diversity of organisms guarantees ecological survival for all lifeforms
Explanation:
REASONS WHY PRESERVATION OF THE EARTH'S BIODIVERSITY IS IMPORTANT-
ECOSYSTEM PRODUCTIVITY - One of the key reasons we should continue to concentrate on biodiversity protection is that it helps to improve the efficiency of the ecosystem. Naturally, a properly working ecosystem would be more immune to extreme environmental factors, such as climate change.HEALTH DETECTIONS -The vast number of medical advances waiting to be made is one of the most significant reasons why we should continue working on saving biodiversity. To develop new cancer therapies and more, scientists use observations of plants , animals, and even microbes. As a matter of fact, all human drugs must first be tested before being tested on humans in laboratory animals. This is essential for determining their toxicity, dosing, as well as effectiveness. In some of the most remote sections of the planet, many of the animals used in these discoveries are also included. Recreation and Natural Beauty - The value of natural beauty is another great explanation why we should continue focusing on protecting biodiversity. There are several historical sites around the country that need to be preserved to maintain their status for future generations to enjoy, such as the redwood forest. These trees regularly have a lifespan of 600 years in the case of the redwoods. Some are as old as 2,000, too. Their growth is extremely sluggish, however. Wild and natural environments provide ways to get away from urban environments. In addition, people can enjoy outdoor activities such as bird watching, canoeing, hiking, and photography of nature. The Ecosystem 'Survival - With a few exceptions, to survive, each species on Earth relies on the services of other species. This partnership is part of the idea of what an ecosystem is. The relationship between soil, plants , and bacteria is a pertinent example. This is known as the period of nitrogen. Other examples which are important include -: Animal waste which nourishes the soil, Crops also produce straw, which is an animal food source, As natural nitrogen fixers, algae represent and Aerate the soil with rats.Economic Benefits -: Many advantages have been provided to humans through biodiversity, and many come in the form of products. These products are extracted and sold, and everything from crops to medicines is included.Hence, preservation of the biodiversity of Earth is important from all aspects of life.
