What may happen to a species whose limited habitat is destroyed by land development

Answers

Answer 1
Answer:

Answer:

extinct

Explanation:

  • The practice of land development like the urbanization and industrialization which leads to rapid and heavy use of the natural resources of the lands and thereby creates pressure on the biological diversity of the lands and thus making it difficult or the survival of the species.
  • The land development practices of the agriculture that leads to the introduction of new species of flora and fauna create a competition of the native species and thus decrease there chances of survival and loss of habitat hence create extinction of the species.
Answer 2
Answer:

it will become extinct

Half of the polar bears in a small population die. This population may experience changes due to _____. gene flow mutation genetic drift natural selection

Answers

Correct answer: Genetic Drift

Genetic drift is defined as the random change in the allele frequency of a population is changed by chance or due to random changes in the environment. It is a random process that can lead to large changes in the overall population in a short period of time. It is a mechanism of evolution and it does produce the adaptation.

Hence, the correct answer would be genetic drift.

Answer:

Genetic Drift

Explanation:

Genetic drift refers to the evolutionary agent that brings about the changes in the gene pool of the population by some chance event. In the given example, half of the polar bear population was wiped out of the habitat by any chance event such as natural calamity, epidemic disease or any other random events. Since no mutation or natural selection was responsible for the death of polar bears, it is an example of genetic drift.  

Genetic drift is more effective in small populations. And the size of the population of the polar bear was also small to allow the genetic drift to cause the changes.  

•What seven characteristics are unique only to marine mammals—not all mammals? •What two Suborders do we classify Order Carnivora into?

Answers

PART 1

1. They nurse their young with milk produced by mammary glands.
2. There are international laws and treaties that protect marine mammals.
3. Unfortunately, many marine mammals are considered endangered species and there are still threats to most of their populations, such as illegal hunting, pollution, climate change, and habitat loss. 
4. They have adapted to living all or part of their life in the ocean.
5. To keep warm in the ocean, most of them depend on a thick layer of blubber (or fat). 
6. To be able to stay under water for long periods, they store extra oxygen in their muscles and blood.
7. They also have more blood than land mammals in proportion to their body sizes, can direct their blood flow to only their vital organs (such as their heart and lungs), and can slow their heartbeat down so they are using less oxygen in a dive.

PART 2
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia

10 differences between animal cells and plant cells

Answers

Answer:

Following are the difference to the given question:

Explanation:

  • Plant cells have a wall of a cell, while cells of animals wouldn't. Cell membranes offer plants support and shape.
  • Chloroplasts in plant cells do not occur, however, in animal cells. Chloroplasts allow plants can grow things via photosynthesizing.
  • Plant cells typically get a vacuole(s) that is one or even more big, whereas animal cells are vacuous, whether any.
  • Large vesicles assist shape the plant and enable food and water to be store for future use.
  • In animal cells, the storing function takes a smaller part and the vacuoles, therefore, are smaller.
  • A plant cell is square in its structural way and an animal cell is often spherical and irregular.
  • The cell of a plant has a vesicle in its big form which is significantly smaller than the plant cell, as well as the animal cell was the or more vacuoles. In general, a vacuole is a storage area for the cells to store water.
  • There is no chloroplast inside the animal cell. Chloroplast is a plant cell that produces photosynthesis from its food. The plants have a green color.
  • The nucleus is located throughout the cell of the plant on the other edge of the peripheral cytoplasm, while the nucleus is in the animal's core.
  • Plant cells store food of starch while animal cells store food of glucose.
  • The mitochondria in the plant are fewer and also have tube cristae, whereas the animal cells have grown in various.

Why is diffusion important for cells? Why is diffusion important for cells?

Answers

Diffusion is essential for cells to bring nutrients and releasing wastes WITHOUT spending energy. This is accomplished by the "urge" of a system to achieve equilibrium, which means that materials tend to flow from high concentration to low concentration area. For example, if a cell lacks amino acids, and therefore has a low concentration of it inside the cell compared to the outside, then by diffusion, the amino acids outside will flow in through the membrane until the concentrations of amino acids outside and inside the cell are the same. All these are done without spending energy from the cell. Note, however, that simple diffusion cannot transport larger particles or those insoluble in lipids; these materials have to be transported with facilitated diffusion, where a carrier on the membrane of the cell will help bring in the materials.
Diffusion is when particles in a more concentrated area move to a less concentrated area, through a semi- permeable membrane. Without diffusion, the cells in your body will not be able to obtain the resources they need to survive, like water and proteins.
