A bird flies at 12.5 meters per second. the wind speed is 4.5 meters per second. what is the speed of the bird when it flies with the wind?
Answer:
17m/s
Explanation:
Given parameters:
Speed of the bird = 12.5m/s
Speed of the wind = 4.5m/s
Unknown:
Speed of the bird when it flies with the wind = ?
Solution:
The speed of the bird when it flies with the wind is the sum of the speed of the bird and the speed of the wind.
Speed of the bird with wind = 12.5m/s + 4.5m/s = 17m/s

The commercial fishing industry uses large nets to capture fish. Often these nets catch many species of organism that are not used by humans. What Change could lessen the negative effect to this practice for the commercial fishing industry?
A. Designing nets that release unwanted species without harming them.
B. Using the net in deeper regions of the ocean where different organisms live.
C. Decreasing the size of the nets, but using more of them.
D. Exploring new and uncharted areas of the ocean where the nets can be used.
Answer:
A. Designing nets that release unwanted species without harming them.
Explanation:
Over-fishing is a negative human practice that leads to the over-exploitation of aquatic ecosystems (i.e., both marine ecosystems and freshwater ecosystems). In an aquatic ecosystem, the communities of organisms coexist in a delicate balance where they are dependent on each other in the food web, providing stability to the whole ecosystem. Therefore, the over-exploitation of any aquatic species is expected to impact the whole ecosystem, thereby also having a negative impact on other fish populations.

Compare the exoskeletons of two invertebrates: a grasshopper (Arthropod) and a clam (Mollusca). How do they differ in relation to support and movement?
Answer:
Mollusca: Unsegmented exoskeleton, with no appendixes articulated to them. This skeleton has a calcareous origin. Arthropoda: Segmented exoskeleton, with different appendixes articulated to them, which develop different functions. This skeleton has a chitinous origin.Explanation:
Clams are bivalves. Their calcareous exoskeleton has two valves dorsally articulated to each other. They do not articulate with any appendix, although. These animals also have a foot, a small head, and a developed mantle cavity. The valves are convex, oval, and unsegmented. They are composed of three layers: periostracum, prismatic, and pearly. En the dorsal portion of each valve, there is a bulge called the umbo, which is the oldest part of the valve. The articulation has some teeth-shaped structures that are intercalated, maintaining the valves together and fixed. Grasshoppers have a chitinous exoskeleton divided into three principal segments or regions that allow their movement: head, thorax, and abdomen. The head is orientated in such a manner that their feeding apparatus is heading down. Also, the head segment has composed eyes and antennae. The thorax is the medial region of the body. It has three segments: the prothorax, mesothorax, and metathorax. Each of these segments articulates with a pair of legs. Finally, the abdomen is composed of many segments that might reach up to 7 or 11.What’s da answer yalll I need help ...

Answer:
Between 80,000 and 400,000 proteins.
Explanation:
In humans, up to ten different proteins can be traced to a single gene. Proteome: It is now estimated that the human body contains between 80,000 and 400,000 proteins. However, they aren't all produced by all the body's cells at any given time. Cells have different proteomes depending on their cell type.

In a typical mammalian cell, what is the average percentage of total cell weight for protein and dna?
Answer:Protein is evaluated at ≈55% of the cell dry weight, followed by RNA at ≈20%, Lipid at ≈10% and DNA at ≈3% (the rest being polysaccharides, metabolites, ions etc.).
Explanation:
A typical mammalian cell averages 18% protein and 0.25% DNA by weight composition.
According to research, a typical mammalian cell is made up of water, ions, and macromolecules such as proteins, lipids, DNA, RNA, carbohydrates, and some miscellaneous metabolites.
The water component of a typical mammalian cell is about 70%, 18% proteins, 1% inorganic ions, 3% small metabolites, 5% lipids, 0.25% DNA, 1.1% RNA, and 2% polysaccharides.

Identify the three types of neurons, and explain the function of each type
Answer:
Sensory neurons help you:
taste
smell
hear
see
feel things around you
Explanation:
Motor neurons
Motor neurons play a role in movement, including voluntary and involuntary movements. These neurons allow the brain and spinal cord to communicate with muscles, organs, and glands all over the body.
Interneurons
Interneurons are neural intermediaries found in your brain and spinal cord. They’re the most common type of neuron. They pass signals from sensory neurons and other interneurons to motor neurons and other interneurons. Often, they form complex circuits that help you to react to external stimuli.
If the atomic number of an element is 6 and its mass number is 13, how many neutrons
are
contained in the nucleus?
19
8
7
6
Answer:
There will be 7 neutrons in a carbon isotope with an atomic mass of 13.
Explanation:
The number of protons in the carbon isotope will be the same as the atomic number, 6, so if we need an atomic mass of 13 there will be 7 neutrons, as 6+7=13.
If the atomic number of an element is 6 and its mass number is 13, there will be 7 neutrons. Therefore, the correct statement is option C.
What is atomic number?Atomic number is the number of protons found in the nucleus of an atom of a specific chemical element. The atomic number is also equal to the number of electrons orbiting around the nucleus in a neutral atom.
Mass number is the total number of protons and neutrons found in the nucleus of an atom and is represented by the symbol A. The mass number is used to determine the atomic mass of the atom.
The atomic number of an element is the number of protons present in its nucleus, which is 6. The mass number of an element is the total number of protons and neutrons in its nucleus, which is 13. So, the number of neutrons in the nucleus can be calculated by subtraction of the atomic number from the mass number.
The formula is number of neutrons = Mass number - Atomic number.
Therefore, there are 7 neutrons in the nucleus of the given element.

If there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons, how much will the action potential rate increase if the stimulus intensity increases by 100?
Answer:
The action potential rate will be doubled
Explanation:
The logarithm of a number for a given base is the power to which the base must be raised to give the number. Logarithm of a number can be in different bases. The base of common logarithm is the base 10.
For example, logarithm of 1000 to base 10 is 3 because 10 raised to power 3 equals 1000
Log₁₀1000 = 3 since 10³ = 1000
Therefore, if there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons and the stimulus intensity increases by 100, the action potential rate will increase thus:
Log₁₀100 = 2
Therefore, the action potential rate will be doubled

What methods would the body use to provide a
person with energy throughout a race?
DONE
C
Intro
Answer:
The methods the body would use to provide a person with energy throughout a race is using the ATP in the muscle cells for the first 3 seconds.
For the next 8 to 10 seconds, the body replaces the used ATP and produces more.
Within the next 90 seconds of the race, anaerobic respiration is used up to make more ATP (Adenosine triphosphate).
Therefore, during the whole process, the three energy systems used are:
the ATP-PC System
the Glycolytic system
the Oxidative system
