The inner planets are closest to sun and solid, like Earth. The outer planets are gas planets with rings, unlike Earth.

They divide the inner and the outer planets because of the asteroid belt

We used new tags for the population estimate a year later. If we assume the tags stay on well over the year, what changes the pr

<h2>Mark and recapture method</h2>

Explanation:

Mark and recapture is a technique to measure the size of a population before fishing and hunting season;commonly used by fish and wildlife managers

It involves the marking of number of individuals in a natural population,returning them to that population followed by recapturing some of those as a basis for estimating the size of the population at the time of marking and release
Population size can be estimated as(N)=M*T/R

here,M=initially marked;T=total in sample second;R=marked recaptures

There are certain assumptions to this method

Population is assumed to be closed which means no new individuals were born or immigrated into the population and none died or emigrated from the population
The chance for each individual in the population to be caught are equal and constant for both the initial marking period and the recapture period
One of the assumption of this method is that sufficient time must be given between the initial marking period and recapture period for all marked individuals but time period should not be very long
Animals do not lose their mark

The tags in the given question were estimated a year there is a chance that old marked tags population might have died or emigrated(the longer the time interval the greater the chance) and hence it becomes an "open" population which violates the first law

If proportion of population changes then marked recapture method formula won't turn out be applicable

To perform a certain type of blood analysis, lab technicians must perform two procedures. The first procedure requires either on

pav-90 [236]

The number of experimental outcomes for the given blood analysis experiment is eight (8).

<h3>What is an experimental outcome?</h3>

Experiment is a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.

After the experiment, the result of the random experiment is known. An outcome is a result of a random experiment.

For the given experiment,

Procedure 1 [n(P1)] can be done one or two steps.

Procedure 2 [n(P2)] can be done in one, two, three or four steps.

So the total number of outcomes (N) in this experiment is;

n(P1)= 2 and n(P2)= 4

N= n(P1) *n(P2)

N= 2*4= 8

The total number of experimental outcomes can also be calculated as (x,y) where ‘x’ is a number of steps of Procedure 1 and ‘y’ is a number of steps of Procedure 2.

Suppose (x,y)= (1,1) means one step is performed of Procedure 1 and one for Procedure 2.

Therefore, (1,1), (1,2), (1,3), (1,4), (2,1), (2,2), (2,3), (2,4) i.e. 8 are the possible outcomes.

When two solvents are separated by a semi-permeable membrane, water flows from low solute concentrations to high solute concentr

daser333 [38]

Answer;

-Water will flow more freely across the semi-permeable membrane

Explanation;

-The movement of water from a region of lower solute concentration to a region of higher solute concentration is called osmosis. It is the net movement of water molecules through a semi- permeable membrane into a region of higher solute concentration (lower solvent concentration).

-Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane.
