Answer:
A population is a group of organisms of the same species, in the same place
A species is a group of organisms that are genetically similar
Explanation:
I like to remember it with humans.
Humans (homo sapiens) are a species. We are all genetically similar and can share genetic material by reproduction.
In a city, a lot of humans are together and that is a population of humans
As a species however, we are all over the place
In making an experiment their are two types of variable that should be consider, one is the dependent variable and the other one is the independent variables. I the question that dependent variable would be the result or the effect of the gender of mice and the independent is the ways in determining it. So the variables should be fair if you want your result to have no bias. Thus the answer would be letter B. because it has the same variables but different in gender
Answer:
The order of events would be:
4.Threshold stimulus, Na+ channels open. This is the first event
5.Na+ influx, Depolarization. Second event
2.Na+ channels close, K+ channels open. This is the third event
1.K+ efflux, Repolarization. Fourth event
3.Hyperpolarization, K+ channels close
Explanation:
In resting state, the membrane is negative inside, and K+ concentration is higher than outside. Na+ concentration is higher outside instead.
Sodium influx is responsible for membrane depolarization. It's the event to produce the action potential. When sodium channels are closing, potassium channels open and K+ go outside until repolarization occurs. But now we have both ions in different sides of the membrane, and this can't be stimulated again to produce other action potential. The membrane will remain refractory to respond to the adequate stimulus until ions migrate to their original sites. This is Na+ outside, and K+ inside. This is responsibility of the Na+/ K+ pump, that uses ATP to pump Na+ out, and K+ in. Once both ions had been relocated in the membrane, this is ready to receive a correct stimulus to produce a new action potential.
Answer:
The red blood cells will burst or rupture when it is diluted and it will be one transparent and visible. ... Because water is an hypotonic solution, water from outside of the cell to the inside making the cells to continue to swell up and rupture ,a phenomenon known as haemylosis.
an industrially developed country
Explanation:
A declining birthrate can be attributed to an industrially developed country. Birthrate is the number of births per thousand of population in a year.
- Several factors contributes to variations in birth rates some of which are:
- Economy
- Religion
- Social structure
- Family planning
- Culture
- Education
- A declining birth rate can be attributed to industrially developed countries.
- In such countries, more women take part in the workforce.
- When women becomes employable and serves as industrial workers, they are not likely to tend to reproduce more.
- This can lead to a decrease in birth rate.
