Heat moves from this source by convection and radiation
Answer:
In CONVECTION, heat energy is carried by the movement of particles of matter. In CONDUCTION, heat is transferred by particles vibrating. In RADIATION, heat is carried directly by electromagnetic waves. When a hot object touches a cool object, heat moves from the hot one to the cool one.
Explanation:
Movement of heat by a fluid such as air is carried out by convection and through electromagnetic via radiation.
What is convection and radiation?Heat is transferred by a fluid, such as water or air, by convection. As the fluid (liquid or gas) flows from one place to another, it also transfers heat. A current is the term used to describe the flow of heated water or air.
Radiation occurs when heat transfers directly from one source to another object as infrared energy waves. This is how the Sun's heat reaches Earth. In actuality, all heated objects emit heat toward colder objects. The molecules of the colder item accelerate as the heat waves impact them. The thing becomes hotter as its molecules move more quickly.

Which of the following explains one of the ways plants and animals depend on each other?
A
Animals make minerals, which plants take in through their roots and pass up to their stems.
B
Animals release water vapor when they breathe, which plants take in through their leaves.
C
Animals make their own food, which plants take in through their roots and pass to their leaves.
D
Animals release carbon dioxide when they breathe, which plants take in to help make food.
Answer:
Animals release carbon dioxide when they breathe which plants take in to help make food
Animals release carbon dioxide when they breathe which plants take in to help make food. So the correct option is D.
Why do animals and plants depend on each other?
All species present on earth depend on each other for performing basic life processes. Humans are not able to survive beyond a particular range of temperature and pressure. For all the species to survive, a healthy environment is required.
Plants and animals are dependent on each other. This is because, in ecological systems, no species can survive alone. Animals are dependent on plants. Plants are the primary producers in our ecosystem. They produce food that is consumed by primary consumers and the primary consumers are consumed by secondary consumers.
Plants use carbon dioxide for photosynthesis and it results in the production of oxygen. This is used by animals for the process of respiration.
Plants depend on animals for several reasons. These can be fruit and seed dispersal, pollination, and also for the carbon dioxide that the animals produce. Thus, both plants and animals are interdependent on each other.
Therefore, the correct option is D.

Conservationistis strive to preserve or improve biodiversity in ecosystems, which includes monitoring populations of organisms to detect changes. Name two challenges that scientists may encounter when they’re monitoring populations of organisms in the wild.
Answer:
Conservationists are responsible to preserve or improve the biodiversity in ecosystem. Many wildlife sanctuaries are made to protect the biodiversity. There are several ways by which conservationists accomplish their aim such as monitoring populations of organisms to detect changes and promoting importnce of wildlife.
Two main challenges conservationists will face while monitoring population of organisms in wild are:
weather conditions may not support the monitoring equipments or clothing.Wildlife animals are dangerous and can cause harm.Hence, conservationists face the above challenges while dealing with wild.
Answer:
One challenge is cost. To effectively monitor populations in the wild, scientists need special equipment such as cameras, computers, and GPS monitoring equipment. Another challenge is accuracy. It’s impossible to count every single organism in an ecosystem, so scientists often work with estimates.

The CRISPR/Cas9 system can cleave genomic DNA at sequences other than the desired target, a phenomenon referred to as off-target cleavage. To avoid off-target cleavage, sites targeted for mutation should appear only once in the genome. What is the minimum length of the part of an sgRNA molecule that binds DNA whose base pair sequence would be expected to be unique within the fruit fly genome
Answer:
correct answer: 14
Explanation:
the question is incomplete, so a graph with the complete questionnaire is attached and the requested question is answered
We will start from the exercise requesting the minimum length that a sequence forms with more than 1.4x10ˆ8 permutations
for this we deduce that two base pairs can have:
4 * 4 = 16 permutations
we deduce that 3 base pairs can have:
4 * 4 * 4 = 64 permutations
Thus we multiply successively until we reach that 14 base pairs can obtain: 2.68x10ˆ8 permutations that are random
Thus, the 14bp sequence will be found only once in the genome of the fruit fly.

Biologists notice that a population of ferrets introduced into a reserve begins to show exponential growth. The figures represent the population of the ferrets for the first four years after their introduction. Which set of figures represents the exponential growth of the ferrets? A. 50, 88, 145, 227 B. 50, 92, 90, 95 C. 50, 32, 17, 9 D. 50, 95, 59, 97
Answer:
A. 50, 88, 145, 227
Explanation:
The correct option would be option A.
When something grows exponentially, it means the growth increased at a high rate. More specifically, each rate of increase results in more or less doubling of the preceding rate. For example, if the current value of growth rate is 2 for a substance that is growing exponentially, the next growth rates will be 4, 8, 16, etc.
In this particular illustration, the only option that best fit into an exponential system is option A in which the growth rate more or less doubles each time from 50 to 88, from 88 to 145, and then from 145 to 227.

g you are given three bacterial cultures: Pseudomonas aeruginosa, Shigella sonnei & Escherichia coli and you carry out a Triple Sugar Iron (TSI) assay for each 1. The tube for P. aeruginosa shows a pink butt, pink slant with no gaps or breaks in the medium and no black precipitate 2. The tube for S. sonnei shows a yellow butt, pink slant with no gaps or breaks in the medium and no black precipitate 3. The tube for E. coli shows a yellow butt, yellow slant with no gaps or breaks in the medium and no black precipitate Which of these organism can reduce glucose but not lactose and/or sucrose?
Answer:
Test Tube 2 (S. sonnei)
Explanation:
Triple sugar iron agar test is the microbiological assay used to test the fermentation reaction performed by the bacteria. The fermentation process differs based on substrate and the acids formed as a byproduct.
The test is based on the byproduct formed as a result of fermentation. The test tube contains 1% lactose, 1% sucrose and 0.1 % glucose, ferrous sulphate, phenol red pH indicator.
When the bacteria ferment any of the three sugar, the medium turns yellow.
In test tube 1- The tube shows pink slant, pink butt and no black precipitate which indicates that no fermentation took.
In test tube 2- the tube shows pink slant, yellow butt and no black precipitate due to fermentation of Glucose only due to alkali acid reaction.
In test tube 3- the tube shows yellow slant and yellow butt which shows that glucose and either lactose or sucrose has been fermented.
Thus, test tube 2 (S. sonnei) is the correct answer.

The size of the iris and pupil can change size. If you walked from a bright room into a dark room, what would happen to the size of the iris and pupil?
Group of answer choices
the iris and pupil would not change size
the iris would get smaller, the pupil would get bigger.
the iris would get smaller, the pupil would get smaller
the iris would get bigger, the pupil would get smaller
the iris would get bigger, the pupil would get bigger
The correct answer is B. The iris would get smaller, the pupil would get bigger.
Explanation
The iris is the name by which the colored part of the eye is known, it is located between the cornea and the lens. In the central part of the iris, there is a round opening known as the pupil. The relationship between these two parts of the eye is very important to sight because between them they control the amount of light that enters the eye. This occurs when the eye is exposed to a high amount of light, the iris muscles make the pupil smaller and the iris larger, limiting light entry into the eye. When the eye is exposed to low amounts of light or darkness, the iris becomes smaller and the pupil enlarges, allowing more light to enter. According to the above, the correct answer is B. the iris would get smaller, the pupil would get bigger. Because it describes the behavior of the iris and the pupil when going from a bright room to a dark room.
why is the moon white
Moonlight is no longer thought of as the cause. In the 16th century, moonmilk, a soft white limestone precipitate found in caves, was thought to be caused by the rays of the Moon.
Answer:
The moon is not actually white, it's grey.
Explanation:
What I learned is that what makes it white is the reflection of the sun and the sun makes it glow, that's why it looks white.
And if you focus on the moon when it's not full you'll see the other part of it showing but it looks grey not white, because as I told you it's the suns reflection.
