What are two ways in which ultrasound technology produces images?
A. By the absorption of sound waves in the body
B. By detecting the frequencies of emitted sound waves
C. By using sound in frequencies that reflect off body tissues
D. By measuring the time it takes for reflected sound waves to be
detected
C and D
Hope this helps have a great day!!
The ultrasound images are produced by using the sound frequencies that reflect off body tissues and by measuring the time it takes for reflected sound waves to be detected. So the correct options are C and D.
What is ultrasound imaging?High-frequency sound waves are used in ultrasound imaging, also known as sonography, to look within the body.
Real-time ultrasound imaging allows for the display of blood flowing via blood vessels as well as the activity of the body's interior organs.
Contrary to X-ray imaging, ultrasonic imaging does not expose patients to ionizing radiation. A transducer (probe) is positioned either on the skin or within a bodily orifice during an ultrasonic examination.
To allow the ultrasonic waves from the transducer to pass through the gel and into the body, a small coating of gel is placed on the skin.
The ultrasound picture is created as a result of the waves' reflection off the body's structures. The information required to create a picture is provided by the intensity (amplitude) of the acoustic signals and the duration of the wave's passage through the body. Therefore the correct options are C and D.

Which of the following could be a hypothesis for the function of the thick,
waxy coating on a pine needle?
A. If the thick, waxy coating is destroyed, the pine needle will turn
brown.
B. The thick, waxy coating prevents water loss.
C. What happens to the needle if the thick, waxy coating is
destroyed?
D. The tree would feel cold without the thick, waxy coating.
Answer:
B. The thick, waxy coating prevents water loss.
Explanation:
This is because the thick waxy coating needle refer to structure posses by plants or mostly xerophites plants to adapt to their environment. Plants that grow in area where there is no abundance of water for use normally posses these structures which will reduce evapotranspiration and conserve water. These plants normally have extensive roots to draw water.
How do we prioritize environmental issues in order to deal with them? What criteria makes one issue
more important than another? Explain
Answer:
Following are some of the most common solutions to the environmental issue:
Replace disposal items with reusable items.The use of paper should be avoided.Conserve water and electricity.Support environmental friendly practices.Recycle the waste to conserve natural resources.Some years ago, before crude oil prices became an economic concern and an international political issue, a biologist proposed a curious-sounding plan. He suggested that a portion of our crude oil supplies be converted directly into edible food, instead of distilling it to gasoline for the typical farming methods for raising food.
Before you become nauseated at the idea, you should know that this conversion has been done on a trial basis. Making edible, non-toxic food from petroleum is feasible. Also, considering that the components of fossil fuels were once ordinary plants and animals in an ordinary food chain, maybe there is some logic in his plan. What does crude oil amount to, anyway, but dinosaur fat? (No, really it is primarily formed from microscopic organisms.)
It might be the right time to form a new corporation and market a new product. What shall we call it…”DinoSnack,” maybe? With interest in dinosaurs as high as it is, how can we go wrong?
Your task is to evaluate this suggestion, allowing for both pro and con, the positive and the negative aspects of it. Surely there will be economic and political considerations, but concentrate especially on the biological, ecological factors.

Correct question:
In the Animals cladogram, which trait evolved two different times?Think and discuss: What could cause similar traits to evolve independently in different species?You will find the cladogram in the attached files.
Answer:
Bipedalism is the trait that evolved two different timesDifferent organisms in different spaces and times face the need to adapt to a similar environment. They manage to solve a problem from that particular ecological niche by developing the same traits, even when the involved groups are not closely related.Explanation:
Through the process of Convergent evolution, two phylogenetically independent organisms get to develop similar structures. These structures make possible a better performance in a similar environment. These organisms are morphologically or ethologically similar in their whole bodies or just in parts.
Convergent evolution occurs in different phylogenetic branches independently from each other. It results from the need for different organisms to adapt to a similar environment and to solve a problem from that particular ecological niche. Ecological pressures acting on them might be similar, modeling the organisms´ phenotype. Each evolutive branch ends by developing the same structures, which they both find effective in their environment.
In the given cladogram, the trait that evolved twice in evolution is bipedalism, reflecting the same need for chickens and humans to adapt to their environment in the same way and according to their habits.

what is your personal responsibility towards the environment? give 100 words
Answer:
My personal responsibility to the environment, as cataloged in the Brundtland report, is sustainability, I mean, ensuring that future generations will be able to enjoy the same quality and quantity of resources that I can have at this time, to I plan to make efficient use of services such as drinking water and electricity, make a correct separation at the source of solid waste so that the reusable material can be used and not cause unnecessary pressure on the earth's mantle, on the other hand, make a more continuous use of reusable or biodegradable material, in order not to increase pollution by waste that usually has as its final destination, in many cases, water sources such as the oceans, as well as reduce my consumption and that of my family of meat products, and products with chlorofluorocarbon gases, thus reducing the amount of gases that are deployed to the atmosphere and could destroy it.
Explanation:
The environmental commitment is something extremely important to allow there to be a true environmental sustainability beyond an advertising attractor, for this it is required that each person identify activities in which they can reduce the generation of pollutants, either through solid waste, dumping or gases. that affect the ozone layer such as methane or chlorofluorocarbon gases, these activities can regularly be carried out from our own homes and, although they may involve additional work, they will allow future generations to enjoy an environment with a quality similar to or better than the one we have currently.

dendritesAxon A cell body or soma9. The process where neurons communicate with one another at junctions is called synapse .
10. Explain the relation between the brain and the five senses.
Ans. The sense organs correspond to a defined region (or group of regions) within the brain where the nerve signals are received and interpreted. Your sense organs include your eyes, ears, nose, mouth, and skin, all have sensory receptors that are specific for certain stimuli. Sensory neurons send nerve impulses from sensory receptors to the central nervous system. The brain then interprets the nerve impulses to form a response.

Bats are natural reservoirs for Nipah virus and do not die from the infection. Knowing this information, would it be more valuable to report data for the incidence or prevalence of Nipah virus in bats (assuming that you also report the total number of bats in the population)?
Answer:
Prevalence would be more valuable
Explanation:
Prevalence is a measure of the frequency of individuals in a population affected by a condition during a particular period of time, while incidence is a measure that indicates the number of new individuals in a population who develop a condition during a particular period of time. Prevalence is different from incidence because prevalence includes all cases of a specified condition (i.e., new and preexisting cases). In consequence, in this case, prevalence is more valuable since it can be used to estimate the total number of infected bats. Conversely, incidence only is informative to determine the number of newly infected bats during a particular period of time, which may not be very informative because all infected bats (i.e., not only newly infected bats) can transmit the Nipah virus infection to humans.

What is the solution to the equation log2 (3x − 4) = 5?
Answer:
The correct answer is - 12.
Explanation:
Given:
log2 (3x − 4) = 5
Solution:
log2 (3x − 4) = 5
3x-4 = 2^5 (∵ lognx = b ⇔ x = a^b)
3x - 4 = 32
3x = 32+4
3x= 36
x= 36/3
x = 12
