An example of the predator/prey dynamic is the rise and fall of the population of Canadian lynx and its favorite prey the snowshoe hare. The two populations were estimated each year for 75 years from the number of animals caught by fur traders. The hare population was found to rise and fall in a ten-year cycle, with that of the lynx following two years later. How does this predator/prey relationship affect the health of a population?

Answers

Answer 1

Heat stroke hypothermia

Answer 2
Answer:

A predator pray is a relationship between two species in which one harms other.

Predator are dependent on prey.

As Canadian lynx eats snowshoe hare and hare population was found to rise and fall in a ten-year cycle, with that of the lynx following two years later.

Explanation:This can be explained in this way, if the food of a specie decrease, after some time that specie will also decrease and if the food of a specie increase after some times, their population will also increases.As the hare decreases, the food for hare will be less in first year they will consume normally eating remaining hare but next year they will start competition each other for food. And their population will decrease due to lack of food and competition.

And when hare increases the number lynx start increasing due to favorable eating condition.

What property of water refers to water's ability to move up the stem of a plant against the force of gravity?
Surface tension
Cohesion
Adhesion
Capillary action

Answers

cohesion force water to move

Answer:

Or i think its capillary action

Explanation:

Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper and plaster, in some non-porous materials such as sand and liquefied carbon fiber, or in a biological cell. It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by cohesion within the liquid) and adhesive forces between the liquid and container wall act to propel the liquid.

Trevor dropped a bit of olive oil on the kitchen floor while he was cooking. Later, his mother slipped on the spot where he dropped the oil and fell.
What can Trevor infer based on his observations?
A.
Olive oil can be used as an adhesive between two solid objects.

B.
The oil reduced the friction between the floor and his mother's foot.

C.
Trevor's mother slipped on the spot where he dropped the oil.

D.
The oil increased the gravitational force on his mother's foot.

Answers

Answer:

B.

The oil reduced the friction between the floor and his mother's foot.

Explanation:

When things slide, it is just fancy terms for one of two things- force exceeding the amount of friction on the ground, or the friction decreasing itself.

In the question, it is implied that Trevor's mom is walking completely normal, excluding the olive oil; therefore, there is no force exceeding what the friction of the ground can prevent from sliding. This leaves the other option, which implies that the olive oil decreased the friction between the floor and his mother's foot, which makes sense as olive oil is a lubricant.

Henceforth, the answer is B. The oil reduced the friction between the floor and his mother's foot.

Answer:

The oil reduced the friction between the floor and his mother's foot.

Explanation:

The activity of k 40 in a 70 kg human body is estimated to be 120 nci what is this activity in becquerels

Answers

The activity of a sample is determined in terms of the number of nuclear disintegrations in a second. The Curie or Ci is a common unit for activity measurement. Bq or Becquerel refers to the SI unit for radiation activity measurement.  

The activity of K-40 in 70 kg human body is 120 nCi

The relationship between Curie and Becquerel are as follows:  

1Ci = 3.7 × 10¹⁰ Bq

1nCi = 37 Bq

Thus, 120 nCi × 37 Bq / 1nCi = 4.4 × 10³ Bq.  

Hence, the activity of K-40 in a 70 Kg human body is 4.4 × 10³ Bq .


Final answer:

The activity of K-40 in a 70 kg human body, given as 120 nCi, is equivalent to 4.44 × 10⁴ becquerels when converted using the appropriate conversion factors.

Explanation:

The activity of K-40 in a 70 kg human body is estimated to be 120 nCi. To convert this activity to becquerels, we use the conversion rate where 1 Ci = 3.70 × 10¹⁰ Bq. Therefore, we first convert nanocuries (nCi) to curies (Ci) by dividing by 1 billion (since 1 nCi = 10⁻¹ Ci), and then multiply by the conversion factor.

Here is the step-by-step conversion:

Convert the activity from nanocuries to curies:
120 nCi × (1 Ci / 10¹ nCi) = 1.20 × 10⁻´ CiConvert the activity from curies to becquerels:
1.20 × 10⁻´ Ci × (3.70 × 10¹⁰ Bq/Ci) = 4.44 × 10⁴ Bq

The activity of K-40 in a 70 kg human body is therefore 4.44 × 10⁴ becquerels.

Answers

A technique psychologists use to measure electrical activity in the brain is A. EEG

Electroencephalogram (EEG) detects the brain activity through electrical signals.

What is EEG?

EEG is a technique where graphical image of the brain is procured using electrical signals.

EEG is exclusively carried out for brain study. It is helpful in diagnosis of seizures and epilepsy.

Multiple electrodes are attached to the brain scalp. A small amount of current in the power source generates electricity.

This produces electrical signals which are carried to the brain. As a result an electrogram is generated on the screen which records the activity in brain.

EEG is an old method of investigation as now several advanced and sensitive tests are available. For eg., MRI, CT-Scan and PET Scan.

EEG is a non-invasive technique. It is simple and easy to perform.

EEG is cost effective as compared to other tests. It does not require large equipment or set up and can be performed at clinic itself.

Therefore, EEG can be used as diagnostic test for evaluation of brain disorders.

Based on this information, what type of transport is used for glucose in blood and intestinal cells?


What type of transport is involved in this process?

Answers

Sugar Glucose is transported by Active Transport from the gut into Intestinal epithelial cells.

Hope this helps.

Davismr00~

Answer:

Transport active.

Explanation:

Glucose is the main source of cellular energy. It is captured by most cells in the body through carrier proteins present in the plasma membrane in favor of their concentration gradient. On the other hand, in intestinal epithelial cells and renal tubules, glucose is captured against its concentration gradient using apical membrane transport proteins and then exits the cell through the basement membrane to enter the bloodstream, in favor of its concentration gradient using membrane carriers known as GLUT's.

Glucose uptake by intestinal epithelial cells always occurs by active transport because it uses a membrane protein in transport even when it is in favor of the concentration gradient.

Which conclusions can be made about the animals of each class based on the structural similarities of the embryos?

Select ALL the correct answers.

1.There is an evolutionary link among the classes.
2.The adults of each class may share structural similarities.
3.Reptiles must have given rise to fish and amphibians.
4.Animals of each class have analogous structures.

Answers

Final answer:

Conclusions that can be made about the animals of each class based on the structural similarities of embryos include the presence of an evolutionary link among the classes and that they may share homologous structures. It is incorrect to conclude a direct lineage such as reptiles giving birth to fish and amphibians from embryology alone.

Explanation:

Based on the structural similarities of embryos, multiple conclusions can be made about the animals of each class:

There is an evolutionary link among the classes, implying that animals with similar embryonic stages may have diverged from a common ancestor. This is evidenced by shared embryonic features such as gill slits and tail structures, which may disappear in adulthood but indicate a common lineage.The adults of each class may share structural similarities due to their embryological development, suggesting that these shared features are homologous structures inherited from a common ancestor.It is incorrect to conclude that Reptiles must have given rise to fish and amphibians based on embryology alone since the linear progression of species is not how evolution operates. Instead, these groups share common ancestors and have evolved separately.Embryonic similarities among different classes indicate that animals of each class have homologous structures, which are traits inherited from a common ancestor, reflecting evolutionary relationships rather than strictly analogous structures which serve similar functions but do not indicate common ancestry.

The presence of similar embryonic stages across diverse groups of animals highlights the concept of evolution from a common ancestor and provides strong evidence for the relatedness of different classes of animals. By studying embryology, scientists can trace the evolutionary paths that have led to the diversity of life forms we see today.

The correct conclusions based on the structural similarities of the embryos are:

1. There is an evolutionary link among the classes.

2. The adults of each class may share structural similarities.

3. Animals of each class have analogous structures.

Based on the options given, the following judgements about the embryos' structural similarities are accurate:

1. There is a connection between the classes through evolution.

The fact that anatomical similarities in embryos frequently imply shared ancestry and evolutionary links between many animal taxa lends credence to this view.

2. There could be structural commonalities among the adults in each class.

This result is tenable because distinct classes of embryos frequently mature into adults with similar anatomical traits derived from their shared ancestry.

3. The structures of the animals in each class are similar.

Although this conclusion is not proved by the available data, it remains a possibility. When a feature in two or more species has a similar function but evolved separately—often as a result of comparable environmental pressures—rather than through common ancestry, it is referred to as an analogy.

As a result, given the embryos' structural similarities, alternatives 1, 2, and 3 are accurate. The available data does not directly support Option 4.

How is co transport used to move glucose into the intestinal epithelial cells

Answers

Co-transport system of intestinal epithelial cells. Glucose then moves into the blood through the permease in the membrane between the cell and the blood. Thus, ATP is used as an energy source to drive Na+ out of the cell, resulting in glucose transport from the intestine to the blood.

Final answer:

Glucose is transported into intestinal epithelial cells via secondary active transport involving the SGLT1 cotransporter, which uses the energy from a sodium ion gradient maintained by the Na+/K+-ATPase pump. This pump exchanges sodium for potassium with ATP hydrolysis, allowing glucose to accumulate in the cell and then diffuse into the bloodstream through the GLUT2 transporter.

Explanation:

Co-transport of glucose into the intestinal epithelial cells is facilitated by a mechanism known as secondary active transport. This process involves the sodium-glucose cotransporter 1 (SGLT1), which simultaneously transports glucose along with sodium ions into the cell against the glucose concentration gradient. The energy for this movement is derived from the sodium ion gradient established by the Na+/K+-ATPase, which pumps sodium out of the enterocyte into the bloodstream in exchange for potassium ions, utilizing ATP. Once inside the cell, glucose then passively diffuses out into the bloodstream through the GLUT2 transporter located in the basolateral membrane. As this transport requires ATP to maintain the sodium gradient, it is termed active transport.

It is essential to maintain a low concentration of Na+ inside the cell to continue this process. Hence, the Na+/K+-ATPase pump expels Na+ ions out of the cell into the blood plasma, maintaining the gradient that powers the SGLT1-mediated glucose transport from the lumen of the gut into the cell.

The correct answer is: B. A person spends one hour each day under the ultraviolet rays of a tanning bed.

The relationships between  ultraviolet (UV) light and skin cancer are highly positive because it has been shown that indoor tanning bed use represents an avoidable risk factor for melanoma and non-melanoma skin cancer. UV light is a form of radiation that causes mutations in DNA by causing the chemical changes that alter the shape of the DNA. So, UV light is a potent mutagen and thus, tanning bed (source of UV light) can cause damage to the DNA in the surface layer of your skin after repeated or prolonged exposure. This might increase the risk for skin cancer.

Final answer:

The pia mater, a delicate layer rich in blood vessels, covers the brain and spinal cord. Conversely, ventricles are fluid-filled compartments where cerebrospinal fluid (CSF) is produced by the choroid plexus. Both pia mater and ventricles are essential parts of the brain's nourishing and protective mechanisms.

Explanation:

The pia mater is a thin, delicate layer that directly covers the brain and spinal cord. It is rich in blood vessels that nourish the central nervous tissue. The ventricles, on the other hand, are fluid-filled compartments in the central nervous system (CNS) where a tissue called the choroid plexus produces cerebrospinal fluid (CSF).

The pia mater and the ventricles are part of the brain's protective and nourishing mechanisms. The brain floats in CSF, which guards it like a cushion, helping to make it neutrally buoyant. Moreover, the CSF also circulates chemical substances throughout the brain and into the spinal cord.

 

The ventricles and their choroid plexuses are a key component of the circulation of cerebrospinal fluid, which also contributes to waste removal from the CNS.

The water cycle also includes some less important processes such as sublimation, transpiration and evapotranspiration.

Thinking about the structure of this "pick-up organ" how is the surface area to volume ratio maximized?

Answers

If we pick small intestine as and organ we can observe its large the surface area/volume ratio. The ration between surface and volume is important, because it impact the function of the organ. In this case, small intestine absorbs the nutrients more efficiently. The surface of the small intestine is increased due to finely wrinkled internal surface and convoluted surface composed of the microvilli (cellular membrane extensions for better absorption).
