What was an unintended negative environmental consequence of improved technology in agriculture?
A. Farmers went bankrupt purchasing expensive equipment.
B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife
C. Machines took away jobs commonly performed by farm workers
D. Machines diminished the quality of the crops.​

Answers

The correct answer is B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife.

Explanation:

In the last decades, the creation of agricultural technology has increased the efficiency of growing crops. This means now, all the process is more efficient, which leads to more products to be sold and an increase in profit. However, the possibility of large scale agriculture has caused more land is used for this purpose. This often implies natural ecosystems such as forests are destroyed and the land of these ecosystems, which is usually rich in minerals, is used for extensive agriculture. This is a negative consequence of agricultural technology as natural areas important for wildlife are taken for human profit.

Explain how conservation has saved the Bald Eagle (Site 1)

Answers

Answer:

Conservation allows the existence of trees essential for the reproduction of bald eagles.

Explanation:

As you may already know, environmental conservation is a term that represents the set of actions and activities that encourage the conscious and sustainable use of natural resources, allowing all environmental factors to be renewed and available in nature for many years.

One of the best consequences of conservation is the reduction of deforestation, which is very beneficial for the Bald Eagle to maintain its species. That's because this species of eagle keeps its eggs in nests raised in large trees. Without these trees, the bald eagle will not reproduce what will end up exterminating its species over time.

Answers

Answer:

Larva and pupa is present in complete metamorphosis while nymph is present instead of larva and pupa in incomplete metamorphosis.

Explanation:

Complete metamorphosis has four stages i. e. egg, larva, pupa, and adult while the incomplete metamorphosis has three stages i. e. egg, nymph, and adult. Grasshopper, dragonfly, cicada and cockroach have incomplete metamorphosis while ladybug , housefly, butterfly  and honeybee have complete metamorphosis. Both type of insects lay eggs and after hatching a baby insect comes out called larva. After sometime this larva transforms from immature to mature, this stage is known as pupa. After pupa, the insect converts into an adult which is ready for reproduction. Nymph is a stage that comes in place of larva and pupa in incomplete metamorphosis. in this stage, the insect is small in size and lack of wings but in adult stage the wings appear.

Jacob calls his friend Mark to tell him the news, and to Jacob's surprise, Mark has heard of MSUD. In fact, Mark says that his wife is a carrier so he got tested to see if he was a carrier as well. After getting tested, Mark and his wife decided to have children because there was no increased risk of their child getting MSUD. Based on this information, Mark and his wife must have the genotype: g

Answers

Answer:

Explanation:

Since Mark's wife was a carrier, it means that she is heterozygous for the trait. And after Mark got tested, they decided to have children due to no increased risk if they do have children, it means the condition is not an autosomal dominant condition but a recessive condition because if the condition is dominant, only one copy of the affected allele is needed to increase risk.

Thus, with a no increased risk, it means Mark is normal i.e. carries no copy of the recessive allele.

ions but you do not want to increase the volume of the blood by reabsorbing large amounts of water from the filtrate. Assuming the aldosterone and ADH are both present, how would you adjust the hormones to accomplish the task

Answers

Answer:

Aldosterone and ADH are part of the renin angiotensin aldosterone system, this system is a system regulated by the kidney and lungs to be able to raise blood pressure.

Explanation:

This system is a retainer of liquids and water, to increase the blood volume of our body, in this way arterial hypotension is compensated.

Another mechanism with which blood volume can be increased is with the stimulation of thirst, and the need to ingest a liquid because of the dry mouth that our central nervous system perceives.

Both mechanisms prevent hypotension and dehydration.

Explain the process of breathing begin with inhalation and describe the route that the air takes to the lungs and what happens when the air reaches the lungs include in your description the terms mouth nose pharynx larynx trachea bronchi lungs alveoli carbon dioxide oxygen and capillaries..... PLEASE HELP PLEASE

Answers

Answer:

Please find the detailed explanation below

Explanation:

The breathing process is the process of breathing in, also called inhalation and breathing out, also called exhalation. Inhalation and exhalation are important processes for a smooth respiratory experience.

Air (containing oxygen) from our external environment enter our body system via our MOUTH or NOSE. The air then passes from the PHARYNX into the LARYNX or voice box, which connects into the TRACHEA or wind pipe, which conveys the air into the lungs via its branched tubes called BRONCHI. These pipes that air passes through in order to reach the lungs are generally called AIR WAYS.

Inhalation (breathing in) involves the taking in of air into the LUNGS (main organ of respiration). It occurs when the diaphragm (muscle separating the thorax from abdomen) contracts and moves downward towards the abdomen. This allows the lungs to expand, allowing air to enter into the lungs via the NOSE or MOUTH down the TRACHEA or windpipe.

As soon as air reaches the lungs, the air passes through the bronchi (tubular branches of the trachea) into the ALVEOLI or air sacs. The delivery of oxygen in the inhaled air is carried out in the CAPILLARIES (a blood vessel that carries blood) that surrounds the alveoli. This alveoli conveys oxygen from the lungs into the bloodstream and carbon dioxide out of the bloodstream into the lungs (a process called GAS EXCHANGE).

Breathing out or exhalation of the carbon dioxide in the lungs (waste product of respiration) occurs when the diaphragm relaxes and moves upward, causing the lungs to deflate as the carbon dioxide is released through the trachea into the mouth or nose where it leaves the body system.

In transduction, the cells that are formed are susceptible to the same antibiotic.
In transformation, a special sex pilus is required to connect two bacterial cells.

Answers

Answer:

In binary fission, the two new cells that are formed are susceptible to the same antibiotic.

Explanation:

Binary fission is the most common type of asexual reproduction in bacteria. Binary fission involves the duplication of the genetic information (i.e., bacterial DNA) and the subsequent separation into two cells during cytokinesis. It is a type of prokaryotic asexual reproduction where replication and segregation are simultaneous processes. Binary fission does not involve the incorporation of new genetic material, thereby the resulting daughter cells will inherit the same genetic information of the parental bacterium, being in this case susceptible to the same antibiotic.

Answers

Answer:

One.

Explanation:

The attached figure shows the diagram of the given question.

We need to find how many angles are alternate exterior angles with angle 5?

Exterior angle = Angle that is made outside of the shape

Alternate angle = an angle opposite of a transversal line of another angle.

From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.

Answers

Answer:

See below

Explanation:

Potassium channels have the ability to allow only potassium ions to pass through with a remarkable accuracy. This is achieved due to the presence of a selectivity filter. There are 8 molecules of water that surround this filter. If the K+ ion is to go through the filter, it will have to lose these molecules. The dimensions of this pore, as determined by its 3D structure, correspond only to the K+ ions and not Na+ ions which are smaller in size and thus, will not be able to pass through the filter.

What is circular cylinder?

A circular cylinder is a three-dimensional geometric shape that consists of two parallel circular bases and a curved lateral surface that connects the two bases. The shape of a circular cylinder resembles a can or a pipe, and it is a common shape in everyday objects and engineering applications.

To calculate the volume of a right circular cylinder with a radius of 2 meters and a height of 9 meters, we need to plug in the given values into the formula: Volume = πr2h. Since π is a constant that is roughly equal to 3, we can use 3 in place of π.

Therefore, the volume of the cylinder is equal to 3 x (2 meters)2 x (9 meters), which is equal to 2,916 m3.

new insecticide is advertised to kill more than 95% roaches upon contact. In a laboratory test, the insecticide was applied to 400 roaches and 384 died immediately after contact. Is this sufficient evidence to support the advertised claim?

Answers

Answer:

Yes! The Commercial is telling the truth that the product kills a good amount, but they are lying when they say it kills 95%. Because it kills 96%!

Explanation:

This is a great question to be asking!

With is experiment, instead of killing 95% of the roaches in the laboratory, it killed 96%. But, it is strange that the commercial did not say 96%. But, to me, maybe that because 95% looks more appealing to the broad audience, instead of a higher number?

Anyways! Hahaha, sorry for getting off topic, but all you need to do to figure this out is to set up a division equation!

Because only 384/400 died, that would be the equation. And when plugging that into a calculator you get 96%.

Fun fact! If the product had killed only 380/400 roaches, then the commercial would be telling the truth.
