Answer:

B. The native species population would decrease because the nonnative species would be competing for food sources.

Explanation:

This question is describing the effect of invasive species. Invasive species are foreign species i.e. not native to a habitat or area, introduced into the area with the ability to outcompete and negatively affect the native species of that area.

Invasive species compete with the native species for food, space, mate etc., and tend to outgrow them. Hence, if a nonnative predator (invasive) species were introduced to an area, the native predator species in that area would decrease because the nonnative species would be competing for food sources.

Answer: The correct answer is respiratory route.

Explanation: Disease can be transmitted from human to human through respiratory route. This can occur when the infected person cough or sneeze into the air , some particles of the pathogens are released and there is any human around the infected person when he sneez or cough, the person tend to get infected by inhaling or breathing in the infected air.

The correct answer is D. Competition.

Explanation

A limiting factor is a term that refers to the scarcity factor of a resource that limits the development and evolution of a specific species or process. According to what is described in the question, it can be inferred that the limiting factor of toucans is competition because the great hornbill lives in the same tropical forest as the toucan, it feeds on the same foods as the toucan: fruit, insects, and walnuts. So, competition for the same resources is a limiting factor for toucans since the absence of food can affect their development. So the correct respect is the D. Competition.

Answer:

The correct answer is - d. Anopheles.

Explanation:

Culex, a species off mosquitoes known as the vector for many viral and parasitic diseases such as elephantiasis, that spread the disease and to one person to other.

In America culex is the main vector for Lymphatic filariasis or elephantiasis that is caused by a parasite. However in Africa Anopheles is the main mosquitoes causes Lymphatic filariasis or elephantiasis in people of the area.

Answer:

both characteristic represent mitosis

The characteristics of certain cell divisions are described in the following table, the two characteristics represent is both characteristics represent mitosis.

Mitosis is a Method in which a single cell divides into two identical daughter cells (cell division).

In this cell divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

Thus, option "B" is correct, Both characteristics represent mitosis.

Answer:

Telophase is the last step of cell division, when chromosomes move in opposite directions so two new cells can be formed from one. When a cell is finishing the process of meiosis, it goes through a phase in which it's basically getting ready to split into two new cells telophase.

Explanation:

the answer is PROTEINS

hope it's helpful for you

Explanation:

I think your answer is D, and let me explain why.

Heat can denature proteins quickly because proteins have very specific temperatures at which they act best. If the temperature rises too high/falls too low with respect to that threshold, then that will cause the proteins to stop working properly and eventually die.

pH is also very important with how proteins work, and it's the same reason as heat. Proteins have a certain range of pH's that keep them healthy and working, but as soon as the pH changes dramatically outside of that range, the proteins will be quickly denatured.

And lastly, organic solvents can denature proteins as well (e.g. alcohol), which makes sense because they are solvents (a solvent is something that dissolves other substances). I'm not sure about the exact chemistry / biological responses behind it, but it's what would be expected of a solvent.

With all of this in mind, I think your answer should be D!

Answer: A.The population of pink katydids will decrease.

B.The population of green katydids will decrease.

Explanation:

The two statements describe what will eventually happen to the population of the katydids are that:

• A.The population of pink katydids will decrease.

• The population of green katydids will decrease.

This is because from the information given, since birds started feeding on the katydids, this will result in the reduction in the number of katydids. Hence, the decrease in both the pink and the green katydids.

Answer: A: The population of pink katydids will decrease.

C: The population of green katydids will increase.

Explanation: The birds that feed on the Katydids will see the pink ones due to the green ones being camoflauged.  The pink katydids will decrease and the green katydids will increase.

Explanation:

what i mean by that is if a substantial amount of pollution enters the water cycle its going to be nearly impossible for it to get out

If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water. It is possible that if ground is polluted than water will also get polluted. It means that the water present on earth is same the water present from the beginning and will continue to be the same water that is available.

Groundwater has been defined as water present in the underground water below the soil as well as in the cracks of the earth. The percentage of freshwater in the world would be 30%. There are mainly three types of groundwater and these are hand-dug wells, as well assprings, and drilled boreholes.

The water stored under the ground has obtained from the rain and stored in the ground so that it can be used later. Ground water has very clean and fit for drinking and the reason could be the soil present on top and work as filter and the groundwater is free from all microorganisms.

Therefore, If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water. It is possible that if ground is polluted than water will also get polluted. It means that the water present on earth is same the water present from the beginning and will continue to be the same water that is available.

Answer:

The answer is "they undergo capacitation"

Explanation:

Sperm migrate through uterine contractions and the energies of its flagella to the uterine tube. In sperm motility, reverse peristalsis is engaged in the uterus and uterine tubes. For a sperm cell to fertilize an egg, it takes approximately 24 hours. The surface of the egg changes as the sperm penetrates the egg, therefore no sperm is allowed within. The kid is fully genetic, including whether it's a boy or a girl at the time of fertilization. Until they are trained it is difficult for sperm to be working.
