What have we learned from fossil evidence about evolution?
Select one:
a. It is an abrupt change.
b. The process is observable.
c. It takes place during one lifetime only.
d. The most complex traits are always selected.

Answers

Answer 1

The process of evolution will need a long time to show a changes. It should not only a lifetime of the organism, but much longer. The long period cause the process hard to observe. The fossil will show that organism that getting a good trait will survive natural selection, while organism with bad trait will be eliminated.
Answer 2

Answer:

B. The Process Is Observable

Explanation:

You can observe all fossils from a billion years ago to now and there will be a change you can see visually.

Explanation:

The urinary system, sometimes referred to as the renal system, manages fluid and electrolyte balance as well as filters and eliminates waste items from the body.

How does the urinary system work?

You must be reduced in size to pass through the filtration membrane and into the renal system on your voyage via the urinary system. The subclavian vein will be used as the injection site, and you must first pass through the heart to reach the arterial circulation. You have at least two minutes to unwind as you move through the systemic circulation before you arrive at the renal artery, which supplies the kidney.

Through the artery wall, you can make out the towering, brownish-red kidney. Once within, the kidney's blood arteries get progressively smaller until you reach the afferent arteriole, which feeds into the glomerulus, the filtering organ. Once inside the filter, you position yourself such that you are facing a pore directly. You are quickly carried across the filtration membrane and into the Bowman's capsule region of the nephron. You lower the specimen cup as you proceed to collect your first test sample of filtrate.

You examine the reading from the sample and discover that, with one exception, its chemical makeup is very identical to that of blood. Practically no blood cells exist. You can wait to take your next sample until you get to the Henle loop, or the "hairpin" in correct language. You observe the tubule cells as you proceed along your path because they have numerous thick fingerlike projections that protrude into the tubule lumen from their surface.

This portion of the tubule is relatively small, therefore these microvilli improve the absorptive surface area. You gather your second sample while in the "hairpin". The readout confirms that the filtrate's content is significantly lower and that few nutrients, including glucose and amino acids, are present.

Here, metabolic wastes are substantially more concentrated, and the area is yellow, which denotes the presence of the urochrome pigment. You know you have arrived in the distal convoluted tubule and are seeing the process of secretion when you gradually work your way up from the 'hairpin' and enter into an area where big molecules are being transported into the filtrate.

As you proceed, you notice that the streams are now more agitated and the water level has plummeted. You recall the function of the hormone ADH and assume that the body must have secreted it to save water. You make a sharp right and then plunge straight down into a tube that is being filled with fluid and other tubes. You become aware that you are moving towards the minor calyx in the collecting duct.

You move very calmly into a tube on the other coast after entering a much calmer area. You become aware that you are experiencing a rhythmic downward squeeze as soon as you enter this tube, indicating that you are in the ureter. You know you have arrived to the urinary bladder when you suddenly drop and splash into a sizable sea of urine. As you can see, there is a lot of fluid as the ceiling gets closer to you and the walls start to pull. Suddenly, you are propelled out of the body and into your host's urethra to leave the body.

Therefore, the urinary system, sometimes referred to as the renal system, manages fluid and electrolyte balance as well as filters and eliminates waste items from the body.

Explanation:

25 x 250

The female otter which weighs 25 kg must consume a total of 6,250 kilocalories per day in order to maintain her body weight.

According to the illustration, otters must consume 250 kilocalories per kg of body weight in order to survive.

A female otter that weighs 25 kg must, therefore, eat 25x of the recommended kilocalories per kg daily in order to main her weight.

Thus: 25 x 250

                    = 6,250 kilocalories

The correct sequence for the general adaptation syndrome is:_________
a) Exhaustion phase, alarm phase and resistance phase
b) Alarm phase, resistance phase and exhaustion phase
c) Resistance phase, exhaustion phase and alarm phase
d) Alarm phase, exhaustion phase and resistance phase

Answers

Answer:

The correct sequence for the general adaptation syndrome is: b) Alarm phase, resistance phase and exhaustion phase

Explanation:

The general adaptation syndrome describes what happens to our body when it is under stress.

The first phase is the Alarm phase. In this stage, the body activates the fight or flight response, causing an increase in adrenaline and cortisol, blood pressure, respiratory frequency, amongst other things that prepare us to react in a situation that we perceive as dangerous.

The second phase is the resistance one. During this phase, the body undergoes a different process that adapts it to manage the stress, with an elevated amount of cortisol and blood pressure.

The third phase is the exhaustion phase. If the stress levels continue to be high, the body passes to this stage. The body is exhausted and cannot keep dealing with stress, which causes mental and physical problems such as anxiety, depression, fatigue, stress-related illnesses, among other symptoms.

State a technology and
explain how it is used to
forecast a future event.

Answers

Explanation:

I don't really know your question but I will tell you what can be predicted.

But how can a technological forecast be made to contain probability dimensions in the same way other forecasts do? Most people think of a technology as a quite specific physical entity. They do not conceive of this entity as having the variable characteristics which would permit range forecasts or probability statements. To their minds, a precisely defined technology either will exist in a given situation, or it will not. And the forecaster must predict this exact event or else he is wrong. This misconception—which would place an impossible demand on any forecaster causes much of the confusion in discussions about technological forecasting.

Posted by;

Ehie, BenjiDev#3339.

Weather forecast would be a technology to determine weather in the future. We would be able to know the humidity and wether or not it’s raining or snowing. So we can dress accordingly and be ready for anything that comes our way. Also the forecast be used to determine bad storms such as a tornado or hurricane. We’ll be notified so we can get to safety or evacuate.
