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 proportion of the old marked tags in the population and make the use of new tags more accurate? (Hint: look back at the assumptions made by the mark and recapture method).a. random loss of tags might sufficiently large to change the proportion of tagged fish.

b. as tagged fish die and larvae that were not tagged reach maturity the proportion of tagged changes.

c. The fish might eat the tags.

d. we cannot assume tags would stay on longer than six months, so we need new tags for the fishfish.

Answers

Answer 1

Answer:

Answer: Option B

Explanation:

It has been assumed that the tags remains on the body of the fishes and is not removed before a year.

The random tags of the fishes can be affected only when there is a high number of fishes born which are not tagged. The proportion of fishes can be affected in this case only.

The number of fatality can be same for both of the fishes, one which were tagged and the ones which were not tagged.

As the tagged fishes die and the larvae of fishes are also not tagged. When comparing both, there is a proportional difference in the number of fishes.

A cell may transport a substance in lysosomes / vesicles if the substance is too large to cross the membrane.

In humans there is a dominant allele (A) for the absence of moles; while the recessive allele (a) results in the presence of moles. A couple who are both heterozygous for this locus (Aa) plan to have seven children. a. Expand the binomial (p + q)7.
b. What is the probability that:
(i) The first child that is born will not have moles.
(ii) All of the children will have moles.
(iii) The first two children will have no moles and the last five will have moles.

c. Assume this couple now have two children, one with moles and one without moles. What is the probability that the child born without moles is a carrier of the a-allele (ie heterozygous)?

Answers

Answer:

a. $(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

b. i. 0.75

ii. 0.000061

iii. 0.012

iv. 0.17

c. 0.67

Explanation:

a. The expansion of the binomial (p + q)7 would be such that:

$(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

b. Both couples are heterozygous:

Aa x Aa

AA Aa Aa aa

Since A is dominant over a,

probability of having mole (aa) = 1/4

probability of not having moles = 3/4

Therefore, the probability of the first child not having moles = 3/4 or 0.75

ii. Let the probability of not having mole = p and the probability of having mole = q. From the binomial expansion:

$(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

Probability that all of the children will have moles = $p^0q^7$

since p = 3/4 and q = 1/4

$p^0q^7$ = $(3/4)^0(1/4)^7$ = 0.000061

iii.Probability that the first two children will have no moles and the last five will have moles = $21p^2q5$

= $21(3/4)^2(1/4)^5$

= 0.012

iv. Probability that 4 will have no moles and 3 will have moles out of the 7 children = $35p^4q^3$

= $35(3/4)^4(1/4)^3$

= 0.17

c. Probability that the child born without moles is a carrier of the a-allele = probability of heterozygous.

From the cross in (b), the genotypes of those born without moles are AA and 2Aa. Therefore, the probability of not having moles and be Aa is:

= 2/3 or 0.67

Sigfried is a science student who develops the following hypothesis: If ants select blue sugar over red sugar, then ants prefer the color blue because it is more soothing than red. What is wrong with Sigfried’s hypothesis

Answers

It is not an issue of color, but rather of sugar content that causes the ants to choose the blue sugar over the red sugar. Because the blue sugar contains more sugar than the redsugar, the ants preferred it.

What is sugar?

All sweet carbohydrates can be referred to as sugar, however the phrase is most frequently used to refer to table sugar, also known as sucrose, or a “double sugar.” Carbohydrates are converted by the body into easily absorbed simple sugars like glucose. There are numerous varieties of sugar.

The body uses sugars and starches from carbs to feed the brain with glucose and give the rest of the body's cells energy.

Most plants have sugars in their tissues. Honey and fruit are plentiful natural sources of simple sugars.

Sugarcane and sugar beet are particularly high in sucrose concentration, making them perfect for effective commercial extraction to produce refined sugar.

Therefore, blue sugar contains more sugar than the red sugar

Explanation:

The ants choosing the blue sugar over the red sugar isn't a matter of color, but it'd a matter of sugar content.

The ants chose the blue sugar because it has more sugar content than the red sugar.
