Which of the following have been changed or altered
due to climate change.
A. Droughts
B. Flooding
C. Melting of polar ice caps
D. All of the above
Answer:
D.
Explanation:
Droughts come from an intense increase in temperature. This causes water/moisture to evaporate from the ground. This is caused by greenhouse gas emissions which makes things a lot warmer. Thus, the temperature rises.
C and B are linked. The icecaps melt which cause the water levels to rise. When the icecaps melt, the water goes into the ocean and causes a rising in the sea level, thus meaning floods can happen.
Droughts, flooding and melting of polar ice caps have been altered or changed due to climate change.
What are the effects of climate change?A change, which comprises both global warming and its influence on the weather patterns of the Earth is known as a climate change. There have been many periods of climate change, however, the present changes are more brisk and are not because of any kind of natural events.
The change in climate is resulting in the melting of polar ice caps, which eventually results in the elevation of sea levels and the oceans are turning warmer than before. Climate change is resulting in more intense droughts and flooding. The continuous change in climate due to human activities are posing a threat to the species, places, and livelihoods.
Thus, the correct answer is option D, that is, all of the above.

If you exert 200 N of force to move a box 8 meters across the living room in 2
seconds, what is your power?
A. 80,000 W
OB. 400 W
C. 1600 W
O D. 800 W
SUBMIT
Answer:
800 W
Explanation:
Power is the rate at which work is done. That is, time taken to do a certain amount of work.
Mathematically, power = work done ÷ time taken
But work done = force × distance/displacement
Then work done = 200 N x 8 m = 1600 Nm = 1600 J (since 1 Nm = 1 J)
So power = 1600 J ÷ 2 s = 800 Js^(-1) = 800 W (since 1 Js^(-1) = 1 W).

I. Invite a healthy test subject to participate in the investigation.
II. Measure and record the pulse and breathing rate of the subject.
III. Have the test subject exercise vigorously for 1 minute, such as by running in place.
IV. Repeat Step 2.
Why is Step 3 useful for Ed's purpose for the investigation?
a Exercise causes an increase in the pH of blood and other body fluids.
b Exercise increases the body's demand for food and nutrients.
c Exercise has no effect on the body's demand for oxygen, food, and nutrients.
d Exercise increases the body's demand for oxygen.
Answer:
d. Exercise increases the body's demand for oxygen.
Explanation:
More oxygen is needed during exercise by the body as compared to normal condition because our body needs energy which is only generated in the process of cellular respiration. In cellular respiration, glucose molecule is broken down by mitochondria of the cell and energy is generated in the form of adenine tri phosphate (ATP) which is used for performing muscular activity. So that's why oxygen requirement is more during exercise.
1. Calculate If 1000 units of energy are available at
the producer level of the energy pyramid, about
how many units are available for first-level con-
sumers? Second-level consumers? Third-level
consumers?
Answer:
first-level consumers- about 100units
Second-level consumers- about 10units
Third-level consumers- about 1unit
Explanation:
A food chain represents the series of energy transfer from one organism to another. This energy is transferred when one organism feeds on another organism. A food chain always starts with a PRODUCER, which is an organism capable of producing its own food via photosynthesis. The producer creates the energy that is transferred as the food chain progresses.
However, only about 10% of the available energy in one organism is transferred to another, this is because most of the energy (about 90%) is lost as heat when the organism undergoes metabolic activities. Hence, if 1000units of energy are available at the producer level, a primary/first level consumer will feed on the producer and 10/100 × 1000 = 100units of energy will be available for the primary/first level consumer.
Likewise, 10% of 100units= 10 units of energy will be available for the second level consumers when it feed on the first level consumers. Lastly, 10% of 10units = 1 unit will be available for third level consumer when it feeds on second level consumer.

Which symbol is used to label a male that expresses a sex-linked disorder on a pedigree? An empty circle. A half-filled circle. An empty square. A filled square.
A Filled square is used to label a male that expresses a sex-linked disorder on a pedigree. So, the correct option is D.
What is Pedigree chart?A pedigree chart is defined as the expression of phenotypic traits in the progenitor and the descendants of different generations in which the circle represents a female and the square represents a male.
If the whole figure is shaded or colored it means that the person is affected. In the parental generation, a single female mates with two males to produce the boy in the first generation, while the sex of the offspring is always dependent on the sperm cell containing the Y chromosome.
When an egg cell with a single X chromosome is fertilized with a sperm containing a Y chromosome it results in a male or if it binds to a sperm having an X chromosome it results in a female. Generally, there is a genetic cross between a male and a female. 50% result in either sex in the offspring.
Thus, a Filled square is used to label a male that expresses a sex-linked disorder on a pedigree. So, the correct option is D.

Cell Division and the Cell Cycle, can anyone write me a essay that is three paragraphs long on that topic. I stink at it
answer:
The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason. ... The two main parts of the cell cycle are mitosis and interphase.
The cell cycle is the replication and reproduction of cells, whether in eukaryotes or prokaryotes. It is important to organisms in different ways, but overall it allows them to survive. For prokaryotes, the cell cycle, called Binary Fission, allows for them to live on by dividing into two new daughter cells.cell division takes place in the cell cycle.
Cell division is the process by which a parent cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. ... Prokaryotes (bacteria) undergo a vegetative cell division known as binary fission, where their genetic material is segregated equally into two daughter cells.
Purpose of Cell Division. Cell division is an essential process for organism creation, growth, and repair. There are two main types of cell division in humans. Cells can divide to make reproductive cells, sperm and eggs.
The cells in our body are highly intelligent. They know when to duplicate themselves and when to rest or stop dividing altogether. ... If the cell passes through each phase and makes it through each checkpoint, then the parent cell replicates and each of the new cells then enter into their first cell cycle.the cell cycle and cell division is very benificial and important for our body.
