A man 1. 72 m tall watches the top of the building AB from a


distance of 48 m. The angle of elevation of the top of the building


from the man's eye is 30°. Then the height of the building is

Answers

Answer 1

We may use trigonometry and the provided facts to establish the building's height. The man is standing 48 metres away from the structure and is 1.72 metres tall. From the man's eye to the top of the building, there is a 30° elevation difference.

To determine the height of the building, we can utilise the tangent function (tan).

tan(30°) = building height / building distance

tan(30°) = h / 48

Calculating the tangent of 30° yields a value of roughly 0.577.

0.577 = h / 48

Rearranging the equation will allow us to find the answer to the question:

h = 0.577 * 48

h ≈ 27.696

Consequently, the building is roughly 27.696 metres tall.

Which of the following has the highest reproductive potential?
O a. bacteria
O b. cattle
O c. humans
O d. elephants

Answers

Answer:

A. Bacteria

Explanation:

I asked my teacher hahahahahahahaha

Bacteria as the highest reproductive potential. Hence option a is correct.

What is reproductive potential?

Reproductive potential is defined as the proportional ability of a species to reproduce itself under ideal circumstances. The maximum number of children that a particular organism can produce is known as its reproductive potential. Compared to other species, some have substantially higher reproductive capacity.

When people reproduce more frequently, sooner in life, and at higher rates, their reproductive potential rises. The largest influence on reproductive capacity is early pregnancy. Every living thing must be able to reproduce. All living things produce additional organisms that resemble them.

Thus, bacteria as the highest reproductive potential. Hence option a is correct.

How is the brain involved with the senses and what is the relationship to the wat a personreacts to objects?

Answers

Answer:

The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. All sensations are electrical signals that travel through neurons which form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis.

Explanation:

The brain is an organ that controls the activity of the body, both its conscious and unconscious functions. It is located in the head and corresponds, therefore, to the encephalon of humans and other vertebrates and is subdivided into forebrain, midbrain and hindbrain.  

The brain acts on the rest of the organism by generating muscle activity or by the production and secretion of chemicals called hormones. Thereby the brain controls responses to changes in the environment. Some basic types of response such as reflexes may be mediated by the spinal cord or peripheral ganglia, but sophisticated intentional control of behavior based on complex sensory information requires the integration of information.

The thalamus, which is located in the central part of the brain, processes and coordinates the messages from the senses that it receives from the body. Five senses are considered to exist: sight, touch, smell, taste and hearing. For that, the information perceived from the outside must reach the brain.

The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. Therefore, all sensations perceived from the outside are electrical signals that travel through neurons. For example, the eyes transform light signals into electrical impulses, which travel to the brain where they are transformed into electrical signals.

Neurons form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis, which is mediated by molecules called neurotransmitters. Since the electrical impulse cannot jump directly from one neuron to another, these neurotransmitters are needed. When the active neuron produces them, the next neuron in the network detects them and becomes electrically charged. Once this has happened, it produces neurotransmitters again so that the next one becomes electrically activated. This is how the electrical impulse reaches the brain.

Your body uses feedback mechanisms to help maintain a stable internal environment called homeostasis. Changes can come from outside or inside the body and the body must respond to these adverse changes to return to a steady state. One such example is what happens when you go for a run on a hot summer day and your body temperature increases. According to the diagram, one of the mechanisms used to cool down is vasodilation. Similar mechanisms are also used when your body temperature drops due to a cold environment. Which of these would NOT help return a body to homeostasis by increasing body temperature?
A) shivering
B) vasoconstriction
C) muscles contract
D) increasing blood pressure

Answers

Answer:

Option D increasing blood pressure.

Explanation:

What is feedback mechanism in homeostasis?

Homeostasis is generally maintained by a negative feedback loop that includes a stimulus , sensor , control center , and effector . Negative feedback serves to reduce an excessive response and to keep a variable within the normal range.

What are the two feedback mechanisms which work to maintain homeostasis?

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

The environmental changes caused by rising sea levels have the potential to alternately increase and decrease the biodiversity of marsh habitats.

What is Biodiversity?

Sum total of all the varieties of living organisms in a particular space, is known as its biodiversity.

As the sea levels steadily rose, it will firstly increase the biodiversity of marsh habitats, but sea level constantly rising, will affect its biodiversity, and organism that is native to marshy habitat should be eliminated while those organisms that are able to survive in inland habitat will migrate into it, overall causing the decrease meant of biodiversity of marshy habitat.

Therefore, the environmental changes caused by rising sea levels have the potential to alternately increase and decrease the biodiversity of marsh habitats.

Which generalization can be made from the data in the table?
1.The higher the temperature, the fewer chirps there will be in 10 seconds.
2.The chirps occur closer together as the temperature increases.
3.The chirps become farther apart as the temperature increases.
4.There is no relationship between temperature and the time between chirps.

Answers

I think it's the third one. But I'm not sure. Hope this helps

The generalization that can be made is: 2.The chirps occur closer together as the temperature increases.

Generalization is a statement you state after making an inference from an observation. For example, we can make a generalization by observing or analyzing the data from the experiment conducted which are given in the table.

From the table given, there seems to be a trend that can be observed. Temperature seems to influence the number of seconds between each chirp of the cricket.

A closer observation of the trend from the data given shows that in general, as the temperature was increased, the seconds between chirps seem to shorten.

Therefore, we make a generalization stating that: "2.The chirps occur closer together as the temperature increases."
