how does asexual reproduction limit variation in species?

Answers

Answer:

less of a chance for mutations

Explanation:

Answer:

Asexual reproduction is a cheap and fast method for producing large numbers of propagules having little diversity. The method of cell division is mitosis, which produces identical daughter cells. This is largely advantageous when survival of offspring is dependent, more upon explosive population growth, than on the diversity of each individual. Plankton species are such an example, where to survive they mostly just need to out produce predation.

Most organisms engage in sexual reproduction at some point in their life cycle to introduce diversity when survival is dependent on susceptibility to parasites. Host — parasite coevolution is an arms race accelerated by diversity.

In sexual reproduction, the method of cell division is meiosis, where diversity is introduced through crossing over, independent assortment, and also, random fertilization.

I believe the answer is A!!!!!

Agricultural technology has evolved over time, with significant leaps during the agricultural and green revolutions.

Agricultural revolution

Agriculture has been one of the sustainers (along with hunting) of early men and as such, has seen gradual development with time. Man has always been looking for better ways to do things in order to achieve outcomes.

With the era of the agricultural revolution, there was a huge transition of humans from the primitive lifestyle of hunting and fruit gatherings to that of agricultural settlements. Better ways to carry out crop production started receiving huge attention. from there, hand-made agricultural equipment started surfacing.

The green revolution has agriculture receiving utmost attention in terms of technological innovations. Farm machinery, agrochemicals, etc, started coming up with the result being a massive increase in crop production and general outputs.

The four steps that a scientist uses to solve a problem are creating hypothesis, experiment, data sorting and writing conclusion.

What are hypothesis?

A hypothesis is an elaboration posited for a characteristic. The scientific technique requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.

Scientists typically base scientific hypotheses on previous findings that cannot be adequately explained by existing scientific theories.

Any process that co-ordinate system data into some defined order to make it simpler to understand, analyze, or visualize is referred to as data sorting.

The conclusion is the final section of an academic essay. The conclusion should restate your response to the question and briefly summarize key points. It does not contain any new points or information.

A scientist solves a problem by developing a hypothesis, conducting an experiment, sorting data, and writing a conclusion.

A botanist finds that when compared to pink flowers, the population of purple flowers is very high. Ten years later, the population of purple flowers is nearly gone, and the number of pink flowers has tripled. Why would this be?

Answers

Answer:

Because of the reduction or near extinction of the purple flowers noticed by the botanist Ten years after it was in abundance, this fall in the population could be caused by the unfavorable change in the plant's environment. While the pink flowers tripled because some factors in the environment were favorable for its growth.

Explanation:

From the question, it was mention that the botanist noticed at first purple flowers had more population than the pink flowers and that changed after 10 years when the population of the pink flowers tripled and purple flowers were nearly gone. Some of the causes that could be responsible are:

1. Disease and pest attack on the purple flowers.

2. The pink flowers developed a good survival mechanism even in adverse conditions.

3. Environmental stress could also come into play on the purple flowers.

4. Climate which initially supported the growth of the purple flowers had changed. Because variations exist in plants and the ideal conditions necessary for plant growths and proliferation varies among plants.

Desert plants and animals are adapted to the lack of what and high

Answers

The two main adaptations that desert animals must make are how to deal with lack of water and how to deal with extremes in temperature. Many desert animals avoid the heat of the desert by simply staying out of it as much as possible

Answer:

lack of water and high concentration of heat and dryness

Explanation:

Deserts don't get that much rainfall, so desert wildlife are adapted to survive in such a dry climate. Take the camel, for instance, it can store three bathtubs of water in it's hump, so it can go a very long time without water. And without that rainfall, the desert is dry and, usually, very hot. Animals have adapted to this by only coming out in the nighttime when it's cooler.

Ideally, by living in an earthship, a person can have a home that is off the grid. People who live in earthships do not depend on outside sources for electricity, food, or water. Building an earthship may be an attractive choice for those who want to use fewer of our planets non-renewable resources.The FoundationFirst, the foundation is built by firmly packing dirt inside recycled tires. Then, the tires are placed in a pyramid-like stack going as high as needed. Next, cement is spread and smoothed between the tires to create a solid wall. When this is finished, the walls are sealed with a protective coating and painted. Some interior walls are built using recycled cans and cement, also sealed with a protective coating.Solar EnergySolar panels give enough stored energy in batteries to provide electricity for appliances, lighting, and electronics. However, solar-powered batteries hold about one-third the charge of energy used in a regular household wired for electricity. This means that people either buy more batteries or intend to use less electricity than a conventional household. Ideally, earthships are built in places where there is an abundance of sunshine year-round.Floor-to-ceiling windows on an earthships south wall also allow plenty of sunlight. It is important that no trees block the light on this side of the house. The sunlight shines directly onto a brick floor, which then absorbs the heat. This provides enough warmth to maintain a comfortable temperature in the house for the rest of the day. This method of heating the home is called passive solar. Most earthships also have either a wood stove or a heater that uses propane, a type of natural gas. These heat sources are useful on cloudy days. During the summer, the combination of the cool temperature of the earth beneath the floor plus the thick walls can keep the house comfortable without the use of air-conditioning.Recycled WaterGutters on the roof collect rainwater that then trickles down into large storage barrels. The water is used for taking showers, doing dishes, and flushing the toilet. It is also filtered for drinking. People sometimes build a greenhouse to grow their own food. Water that has been used for dishwashing or showers can be saved if the soaps are chemical-free. This recycled gray water can be used yet again to water the plants in the greenhouse.Potential ProblemsEarthships have been around since the 1970s. Now, long-term studies have revealed some problems. For one, without sufficient sunlight during the winter, large amounts of natural gas known as propane and/or wood are used to heat the home. Propane use can be costly, and unless one has planned far ahead, a wood supply can be quickly depleted.Another problem is that tires used in the foundation walls can, after a long period of time, begin to crack, releasing a toxic gas that has built up over time in the walls. The use of cement, which is a porous material with many small holes and spaces, allows the gases to leak into the air. The type of gas emitted is not detectable by smell but can make people sick. To address this problem, the walls of the home needs to be resealed every year.Cost can also be a significant challenge. Some earthship building companies claim that it is far cheaper to build an earthship because only recycled materials are used. Also, a contractors license or training is not needed to build one. This, though, is true if it is built 100% by the owner, which could take years to complete. Additionally, the cement, plumbing, and electrical components, as well as the cost of installing solar panels, can be expensive. Just as with the construction of a conventional home, proper permits are often needed to build an earthship.There are clear advantages and disadvantages to these unique homes. As technology improves and new solutions are discovered, earthships may continue to be a wise way to live sustainably using minimal resources.Based on the passage "Earthships," what does the term gray water mean?Question 12 options:reusable wastewaterfiltered drinking waterpure spring watergutters that collect rainwater A $1,500 savings bond earns simple interest at the rate of 5% each year.
