Answer:

C. Hypotheses can be proved through experimentation

Explanation:

When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.

Answer:

Consumers must obtain their nutrients and energy by eating other organisms. Decomposers break down animal remains and wastes to get energy.

Is selection more effective against recessive alleles in haploid or diploid organisms?

svet-max [94.6K]

The selection of more effective which is against recessive alleles in haploid organisms than diploid organisms. This is because haploid organisms contain a single set of alleles if a deleterious allele is present in haploid organisms which will produce its effect immediately as there will be no dominant allele which can prevent the expression of the recessive allele as it happens in diploids. Recessive allele will not produce its effect in presence of the dominant allele in the case of heterozygote which is Aa.
Where there is haploid the selection will be more effective when removing recessive alleles in the population. It is the homozygous recessive condition which as aa then the selection will act against recessive alleles.

Consider the following hypothetical population and compute the statistical measures below: #births = 50,000; #deaths = 10,000; #

777dan777 [17]

Answer:

The birth rate refers to an average number of births in one year per thousand individuals in the population at mid-year.

BR = (total birth in an annum / total population in mid year) * 1000

BR = (50000 / 1000000) * 1000 = 50

Death rate refers to an average number of death in an annum per thousand individuals in a population at mid year. Thus,

DR = (total death / total population in mid year) * 1000

DR = (10000 / 1000000) * 1000 = 10

Annual population growth rate or APGR is calculated as:

APGR = (Birth rate - Death rate) / Death rate

APGR = (50 - 10) / 10 = 4.0 %

Doubling time is the whole sum time needed for a population to get double in size. It is calculated as DT = ln (2) / growth rate

70 / 4.0 = 17.5 years

Thus, population will get double in 17.5 years.

Adjusted (true) growth rate is equal to APGR + (NMR / Death rate)

And NMR = [(immigrants -emigrants) / total population] * 1000

NMR = [(5000 - 20000) / 1000000] * 1000 = -15

Thus, Adjusted (True) growth rate = 4.0 + (-15 /10) = -6%

The adjusted (true) doubling time = ln (2) / Adjusted growth rate

= 70 / -6 = -11.66

This negative sign shows that it will never get double in such situation.

Science fusion grade 7 lesson 1 review

4) The simplest type of response is a direct one-to-one stimulus-response reaction. A change in the environment is the stimulus; the reaction of the organism to it is the response. In single-celled organisms, the response is the result of a property of the cell fluid called irritability.

5) During meiosis, the cells needed for sexual reproduction divide to produce new cells called gametes. Gametes contain half as many chromosomes as the other cells in the organism, and each gamete is genetically unique because the DNA of the parent cell is shuffled before the cell divides.

6)Producers can make their own food by capturing the sun's energy, but consumers and decomposes can't. Consumers need to eat other organisms to obtain energy. Decomposes are like the recycles of nature. They obtain energy for their own needs while returning simple molecules to the environment.

7)The birds are growing up into a larger bird.

8) Cells manage a wide range of functions in their tiny package growing, moving, housekeeping, and so on and most of those functions require energy. But how do cells get this energy in the first place? And how do they use it in the most efficient manner possible?

9)Aside from the fact that fish,and trees can be aged in similar ways (by counting annual growth rings), new research shows that all three also respond to climate change in similar ways.

10)No we will not be able to survive cause there is no food or water and it is only oxygen of course you will be able to breathe but not eat or drink.
