Two species benefit from interaction with each other
Example: A hummingbird gets food from the nectar of a flower and then spreads the nectar’s pollen, helping the flower reproduce.
: One species benefits from the interaction, and the other species is harmed but not necessarily killed
Example: Ticks feed on other animals’ blood, which can hurt the other animals.
: One species benefits from the interaction, and the other species is neither helped nor harmed
Example: Egrets rely on cows to stir up dirt and bring food to the surface, but cows do not benefit.

One of the bacteria in Model 1 has a tail-like structure.
a) What is the structure called?
b) What might be the purpose of this structure?
c) Based on your answer of the previous question, what might you infer about the absence of this structure in the other two bacteria cells?
From the bacterial model:
(a) the tail-like structure is known as the flagellum (plural, flagella)
(b) The primary function of the structure is to aid movement. It is moved in a whip-like version to propel the organism.
(c) Based on the absence of of flagellum in the other two bacteria, it means that they are not motile.
The presence of flagellum in bacteria is an indication that such bacteria are motile. The thread-like structure is whipped randomly in order for the organism to move and the absence of it in an bacterium is an indication that such a bacterium is not motile.

Put the steps of cloud formation in order. 1 should be the first step and 4 will be the
last step.
Rising air currents organize into "thermals"
Sunlight warms the surface and water evaporates
Warm, moist layer builds up between 1000 and 5000 feet
Water vapor in rising air parcels condenses to form clouds
The correct order in cloud formation include the following:

explain how pH and temperature can affect enzyme activity
Please help has to be due in 20 mins. Thank you for helping me.
Answer:
Enzyme activity depends on many factors such as Substrate concentration, enzyme cofactor, enzyme inhibitors, pH, and temperature. pH and temperature are two important factors that directly affect the activity of an enzyme as follows:
1. pH
Each enzyme has the specific optimal pH that allows it to perform its function to its fullest. The enzymes are the protein made up of the interaction of the hydrogen bond in the side chain of the protein. if there is any change from optimum pH, the enzyme activity decreases until it stops working.
2. Temperature:
Each enzyme has its own optimal temperature. Any modification or change in temperature results in the activity of an enzyme, and it also leads to the denaturation of an enzyme as it is made up of protein.
What 3 letters on mRNA is used for the start codon?
Answer:
The codon AUG, commonly known as the start codon, specifies the amino acid methionine. As a result, during protein synthesis, methionine is the first amino acid to dock in the ribosome.

what is the function of the pupil and Iris
The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil. These muscles can control the amount of light entering the eye by making the pupil larger (dilated) or smaller (constricted).

Why do deserts tend to form on land at latitudes of 20-30 degrees north and south?
Answer:
Deserts can form even on tropical coasts beside cold ocean currents, such as the west coast of South America. The currents cool the air, which then rises and warms as it moves over land, drawing up moisture that is later precipitated as the air moves farther inland.

What is condensation? Describe a way in which it can affect Earth systems.
12pt v
Paragraph
IB в I o Ауду т?у а
Answer:
Condensation is a process in which water vapors changed into liquid state.
Explanation:
Condensation is a process in which water that is present in the vapors form changed into liquid state. Condensation greatly affect Earth systems because this process is responsible for the precipitation on the earth. Condensation occurs in the atmosphere when warm air rises in the atmosphere, cools and unable to hold water vapor. As a result, water vapors condenses to form cloud droplets that falls in the form of rainfall.
True or False: When a biotic factor dies, the molecules within that
organism enter into the nutrient cycle.
Answer:
Explanation:
True
When a biotic factor dies, the molecules within that organism enter into the nutrient cycle is a true statement.
Biotic factors:
There are two factors in a living system. Biotic and abiotic. all living organisms are biotic components. Plants, animals, and other living components are biotic components. Air, water, and sunlight are abiotic components.
Biotic and abiotic components together make the nutrient cycle. When biotic components die their molecules enter the nutrient cycle. Microorganisms act on the biotic component when they die.
They release carbon, hydrogen, and other molecules into the atmosphere when they die.
Therefore, When a biotic factor dies, the molecules within that organism enter into the nutrient cycle is a true statement.

BT crops are developed by adding traits from which of the following organisms?
phytoplankton
bacteria
viruses
superweeds
Answer:
bacteria
Explanation:
'Bt' crops are genetically modified crops that contains a certain gene of a bacteria called Bacillus thuringiensis. The name of this GM or transgenic crop was coined from the bacteria used.
The gene coding for the toxic traits of the bacteria are added into Bt crops e.g cotton, hence, the crops become resistant to pest attack. Therefore, according to this question, BT crops are developed by adding traits from BACTERIA.
