Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetah.

Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.

According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.

Farmers brought nutria, a type of large rodents, from South America to North America in the 1990s. They wanted to raise the rodents for their fur. Some of these rodents escaped into the wild and became a major pest in the Gulf Coast and Chesapeake Bay regions. Grasses and shrubs in these regions are vital, because they provide food and shelter for many species. They also help in preventing soil erosion. The nutria are eating up all the grasses and shrubs, which affects the food cycles of these regions. The entire ecosystems are being disrupted.

Moreover, nutria pose a direct threat to humans. These rodents are an effective vector for carrying parasites that can cause disease in humans. They also damage property. The burrows created by nutria can damage dams and building foundations as well as cause erosion near streams and lakes.

the answer from pluto/edmentum

Answer:

The apple snail is a native species of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Southeast Asia legally imported this alien species to use it as a protein source. Later, this species was brought to places like Hawaii as a source of food.

Like most, if not all, invasive species, the apple snail outcompetes native species for resources. This is because it reproduces rapidly (laying hundreds of eggs every few weeks) and lacks predators. As a result, the snails spread rapidly to aquatic biomes and modify the natural balance of aquatic ecosystems.

what do you think is a way for geologist to locate ore bodies? justify your answer​

From my research, there is lots of information on how to extract ore, but I can't find any information on how these ore deposits are found in the first place, apart from 'looking for surface formations'. So, what kind of formations would exist for different types of ore? Are there any other ways of finding ore?

The reason why it is important for gametes to be haploid cells is because: when the sperm and the egg fuse together the living sex cells will have 46 chromosomes.

Gametes are also referred to as sex cells and they can be defined as the reproductive cells in a living organism.

Generally, the male reproductive cell is known as a sperm while the female reproductive cell is known as an egg.

Since gametes are reproductive cells or sex cells, they are typically made up of haploid set of chromosomes.

Basically, it is very important for gametes to be haploid cells so that when the sperm and the egg fuse together, the living sex cells will have a total of 46 chromosomes.

Answer:

C

Explanation:

Prokaryotic cells do not have any membrane-bound organelles, only eukaryotes do.

The prokaryotic cell is a simple primitive cell, unlike the complex eukaryotic cells. The absence of a membrane-bound nucleus is a characteristic of prokaryotes. Thus, option C is correct.

Prokaryotes have been the cells that have lived on earth for millions of years ago. They are made of single cells and hence are unicellular. Unlike the eukaryotic cell, they have simple mechanisms of living and reproduction.

They lack a centrally located defined nucleus that is not covered in any membrane and lies simply in the cytoplasmic material. Also, they lack organelles that make them different.

The genetic material is located in a concentrated form in a structure called the nucleoid that lacks a nuclear membrane.

Therefore, option C. the prokaryote lacks a membrane-bound nucleus.

Answer: Haiti is mainly know for their minerals! the main minerals extracted are: cooper, silver, and GOLD. Haiti has many many gold farms, markets, etc. HOWEVER this is a very poor area, as people here live off of only about 2 dollars per day. They could take this wealth and put it towards the people, roads, and construction, as they had an earthquake that killed many many people, and destroyed much. If you mean what they do with gold, they take the gold from farms, and mine it underground. They then sell it for money as this is a poor area as said before!

Answer:

Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock.

Explanation:

The tropical hardwood hammocks are habitats that act as small ecosystems markedly different from the surrounding environment, and they may be seriously threatened by introduced plant species. In Florida, exotic plants have been introduced into the tropical hardwood hammock habitat, reaching to about 50% of the flora in some areas. The mature hammock of these habitats can generate a shade that maintains a temperature of several degrees cooler compared to their neighboring habitats, and thereby promoting invasion by exotic species.

Your answer would most likely be: C. It produces gametes that are needed for sexual reproduction.

Explanation: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

Hope this helps! Have a nice day!

Answer:

C. to produce a new cell

Explanation:

Mitosis consists in replicating the genetic material of a mother cell in order to make two identical daughter cells; this is a diploid process. In order to make an egg or sperm cell and eventually a new organism, the correct process would be meiosis, since it combines the DNA between two cells and it is an haploid process.

Explanation:

A dog burying a bone in the backyard is not an observation in terms of scientific methods.

Observation is the process of acquiring data about a phenomenon under study.

Most times, senses are used in making observations. Our sense of taste, hearing, sight etc. comes handy when making observation.

Also, we can use some specialized equipment to make observations.
