A grassy meadow high in the Sierra Nevada Mountains of eastern California is known to support a variety of organisms. During the summers when grass is thick and lush, and wildflowers abound, butterflies take advantage of this abundant nectar source. Bears graze on the berries in shrubs at the edge of the meadow. Deer also forage at the edge of the meadow. In the early mornings, coyotes are known to prey on the squirrel and mouse populations that burrow into the meadow soil. A variety of birds prey on the butterflies and other flying insects, such as bees and wasps.​


If the biomass of flowers that support the butterflies was known to contain 100,000 units of energy, and certain bird species were eating the butterflies that foraged on the flowers, what amount of energy, on average, could be expected to be transferred to the birds?​
Group of answer choices

​a)100

​b1,000

​c10

​d10,000

​e50,000

Answers

Answer 1

Answer:

b) 1,000

Explanation:

In a typical food chain as described in this question, flow of energy occurs from one organism to another when they feed/fed upon. As one organism feeds, energy gets transferred to it. However, only about 10% of the available energy in the lower trophic level gets transferred because majority of the energy (about 90%) is lost as heat during metabolic processes of the organism.

Hence, if a flower contains approximately 100,000 units of energy and is fed on by butterflies. 10% of 100, 000 = 10,000 units gets transferred to the butterflies.

Likewise, the butterflies gets fed on by certain bird species. 10% of the available 10,000 units of energy in the butterfly gets transferred to the birds.

= 10/100 × 10,000 = 1000 units of energy.

Name the main energystoring products of each phase of photosynthesis.

Answers

Just the way you justify it and otherwise on the same point slot

Explanation:

During the first stage of photosynthesis, called the light-dependent reaction, sunlight excites the electrons in the chlorophyll pigment. The organism uses this energy to create the energy carrier molecules ATP and NADPH, which are crucial for carbon fixing during the second stage.

The first two stages of photosynthesis depend directly on light because light energy is used to make ATP and NADPH. In the final stage of photosynthesis, ATP and NADPH are used to produce energy-storing sugar molecules from the carbon in carbon dioxide.

The more time people spend using social media, the less they read books.

Dependent Variable:​

Answers

Answer:

Independent: Time on Social Media

Dependent: Less books read.

The Independent variable is ;  Time spent on social media  while The dependent variable is : Number of books read

An independent variable in an experiment is a variable whose outcome is not affected by other variables present in the experiment.   while

A dependent variable is a variable whose outcome is directly determined/affected by changes made by an independent variable in the experiment.

The number of books read is a dependent variable because it depends on the amount of time spent on social media ( independent variable ).

Hence we can conclude that the Independent variable in the experiment is the time spent on social media while the number of books read is a dependent variable.

Give an example that illustrates lipids being waterproof.

Answers

Answer:

Oils do not dissolve in water

Explanation:

Waxes are one of the forms of lipids, which are waterproof.  

Lipids are insoluble in water and are hydrophobic. They perform many essential activities within the cell.  

• One of the forms of lipids is waxes, which envelopes the leaf surfaces of some plants, and the feathers of some aquatic birds.  

• Due to the hydrophobic nature of waxes, they inhibit water from attaching to the surface. Thus, waxes are waterproof.  

• The waxes are the long-chain fatty acid chains attached covalently with the long-chain alcohols.  

Thus, waxes are the lipids that demonstrate the waterproof property of the lipids.

Is controlling homeostasis a conscious or unconscious process?

Answers

Answer:

It is an unconcious process

Explanation:

Homeostasis is when the body is made sure to have a constant environment inside so that the body can work at it's optimum conditions .... constant temperature, constant pH etc ... you do sweat when you feel hot but you can't control it... your mind just tells it to... vadodilation and vasoconstriction for a constant temperature occurs for a constant temperature as well(when vessels dilate and constrict), your mind allows the vessels to do so without you thinking about it.

Homeostasis is an unconscious process.

Homeostasis can be defined as the ability of the organism to maintain the internal environment constant with respect to the changes occurring in the external environment. The steady state of the body can be achieved by the regulation of body temperature, pH, and metabolism. These changes are controlled by the hypothalamus gland in the human body which is without our conscious state of awareness. Some of these changes are control of heart rate, body temperature, and blood pressure.

Hence, controlling homeostasis is an unconscious process.

the results of the investigation led to new scientific questions

Explanation:

The basis of every scientific question asked is an observation made. Scientific questions are questions that emanate from an observed problem and leads to the formation of a testable explanation (hypothesis). In this question, an investigation was made by a scientist and it was discovered that increased temperature decreases the number of offspring that an organism produces.

However, the scientist asks a new question about the impact of climate change on the species. This is because an observation has been made again, from the previously concluded investigation. Hence, after completing the investigation about the effect of temperature on the number of offsprings an organism can produce, an observation was made, ultimately leading to a new scientific question.

I hope that this helps you !

The difference between physical and chemical properties of a substance depend on the fact that they affect the substance physically or affects its properties and identity.

Substances have characteristics that help in identify and thus classify them. Two of the broad classifications of these would include the chemical and physical properties of a particular substance.

Physical properties are those that can be identified without changing the identity of the substance.change in the physical appearance of matter such as color, density, hardness , are examples of physical properties.Properties that describe how a substance changes into a completely different substance are called chemical properties.Flammability and corrosion resistance are examples of chemical properties.

Thus, the physical and chemical properties of a substance depend on the fact that they affect the substance physically or affects its properties and identity.
