Answer:
The correct answer is "Statistical Hypothesis".
Explanation:
Given the example, the breeder wants to find the relationship between the two variables which are the effects of bredding and the face length of the boxer breed. He/She is using the statistics of the face length from the years 1915 and 2015 so the type of hypothesis that should be used is "Statistical Hypothesis" which is used when the hypothesis can be verified statistically. I hope this answer helps.
Answer:
Na+ only
Explanation:
Depolarisation of membrane refers to the change in the resting membrane potential of the membrane of a cell which is usually -70mv to a more positive value.
This value changes when the positive ions move inside the cell which increases the positive charge inside the cell.
In the myocardial cell, the sodium ions move inside the cell which changes the potential towards the more positive side as a result of which the signals for contraction arises.
Thus, Na+ only is correct.
In the earliest stages of development, all four organisms have a knobby head, gill slits, and a tail. These similarities tell us that all four of these organisms have a common ancestor.
Non native species are organisms that do not naturally occur in a given area. They may have been transferred either accidentally or deliberately from their place of origin to the new area through human activities.
Non native species may become invasive species if they cause harm to the economy, human health, or environment.
Control methods used to eliminate invasive species are:
1) mechanical - physically removing the invasive species or changing the habitat condition of the affected area.
2) chemical - using of pesticides, fungicides, or herbicides to kill off invasive species.
3) legislative - introducing the natural enemy of the invasive species. It may be a predator or parasite that is from its native range.
Answer is;
The animal population in the environment will increase.
This is because the grass is the main producer in a habitat. Its plentifulness directly influences that of the consumers up the food web. Increase in grass population means reduced competition for primary consumers and their population will therefore increase. This will also reduce competition for secondary consumers and tertiary consumers up the chain.
