Two positively charged objects (Object A and Object B) are 8 inches apart. When a positively charged ball is hung at an equal di

stance between the two positively charged objects, the ball moves toward object B (see figure).
What can you conclude about the relative amount of positive charge on Object A and Object B? Provide support for your claim.

Answer:

Object B has more charge than Object A

Explanation:

Generally, unlike charges attract each other and like charges repel each other but it happens in a very rare case when like charges attract each other. It is so due to charge difference between the objects.

In the given example a positively charged ball moves towards positively charged object B because object B has more charge than object A and the ball. Due to large difference in the charges between two positive charges, positive charges are displaced at opposite end and object B get concentrated with negative charges that allows ball to move towards Object B.

Hence, the correct answer is "Object B has more charge than Object A".

The count in a bacteria culture was 100 after 20 minutes and 2000 after 40 minutes. Assuming the count grows exponentially, What
Afina-wow [57]

Answer:

Explanation:

Let X be the number of bacteria at time t, and Xo be the initial number of bacteria

Bacteria grows exponentially, the exponential growth model is thus:

X = Xo e^{kt}

[<em>e</em> is the exponential sign]

k is the growth constant = growth rate

At t = 20 minutes, X = 100

At t = 40 minutes, X = 2000

Substituting that into the formula

(i) ...    100 = Xo e^{k20}

(ii) ...    2000 = Xoe^{k40}

<em>Divide (ii) by (i)</em>

\frac{2000}{100} = \frac{Xoe^{40k} } {Xoe^{20k}}

20 = e^{40k-20k} = e^{20k}

<em>[Xo cancels Xo. Division of values raised to a power is done by subtracting their powers]</em>

<em>Take the natural log of both sides</em>

㏑20 = 20k

<em>[taking the ㏑ cancels the exponential]</em>

k = \frac{ln20}{20}

<em>We can now substitute k to solve one of the equations</em>

<em>substituting k in (ii)</em>: 2000 = Xo e\frac{ln 20}{20}.^{40}

2000 = Xo e^{0.15*40}

2000 = Xo e^{6}

<em>Making Xo the subject of the formula</em>

Xo = \frac{2000}{e^{6} }

Xo is approximately 5 cells.

THE DOUBLING TIME

The doubling time is the time it takes for the population to double, so 5 cells become 10 cells

Since Xo = 5

Given that X = Xo e^{kt}

When X=10,

10 = 5 e^{0.15t}

<em>solving for t:</em>

e^{0.15t} = \frac{10}{5}

Take ln of both sides

0.15t = ln 2

t =\frac{ln2}{0.15}

t =4.62 minutes

POPULATION AFTER 65 MINUTES

X = 5 e^{0.15*65}

X = 85770

WHEN WILL THE POPULATION REACH 12000

12000 = 5 e^{0.15t}

e^{0.15t} =240

take ln of both sides

0.15t = ln 2400

t = 51.89 minutes (approximately 52 minutes)

Answer: Your answer would be C

Explanation:

Freckles are associated with a variant of a gene called MC1R. MC1R alerts the body when exposed to harmful UV radiation is taking place. This is a dominant gene, meaning anyone with at least one copy of the freckle variant from either parent will have freckles. You can also Can you permanently remove freckles?

There are several treatments that can remove freckles. Over long periods of time, avoiding sun exposure and using sunscreen can cause some freckles to disappear. However, completely removing freckles usually requires medical treatment.

What are some examples of how mutation aides genetic variation?
dangina [55]

Why study human genetics? One reason is simply an interest in better understanding ourselves. As a branch of genetics, human genetics concerns itself with what most of us consider to be the most interesting species on earth: Homo sapiens. But our interest in human genetics does not stop at the boundaries of the species, for what we learn about human genetic variation and its sources and transmission inevitably contributes to our understanding of genetics in general, just as the study of variation in other species informs our understanding of our own.

A second reason for studying human genetics is its practical value for human welfare. In this sense, human genetics is more an applied science than a fundamental science. One benefit of studying human genetic variation is the discovery and description of the genetic contribution to many human diseases. This is an increasingly powerful motivation in light of our growing understanding of the contribution that genes make to the development of diseases such as cancer, heart disease, and diabetes. In fact, society has been willing in the past and continues to be willing to pay significant amounts of money for research in this area, primarily because of its perception that such study has enormous potential to improve human health. This perception, and its realization in the discoveries of the past 20 years, have led to a marked increase in the number of people and organizations involved in human genetics.

This second reason for studying human genetics is related to the first. The desire to develop medical practices that can alleviate the suffering associated with human disease has provided strong support to basic research. Many basic biological phenomena have been discovered and described during the course of investigations into particular disease conditions. A classic example is the knowledge about human sex chromosomes that was gained through the study of patients with sex chromosome abnormalities. A more current example is our rapidly increasing understanding of the mechanisms that regulate cell growth and reproduction, understanding that we have gained primarily through a study of genes that, when mutated, increase the risk of cancer.

Likewise, the results of basic research inform and stimulate research into human disease. For example, the development of recombinant DNA techniques (Figure 3) rapidly transformed the study of human genetics, ultimately allowing scientists to study the detailed structure and functions of individual human genes, as well as to manipulate these genes in a variety of previously unimaginable ways.
