Which population is most likely to have exponential growth?
O A. The dust mites living in a sofa that is often used and never
cleaned
B. The angelfish living in a coral reef where there are many sharks
C. The mice living in a meadow with plenty of predators and limited
food
D. The foxes living in a forest where they compete with other animals
for food
Answer:
A. The dust mites living in a sofa that is often used and never cleaned
Explanation:
Without the sofa being cleaned, the dust mites will never experience any predation or die off from humans and harsh cleaning chemicals. This will enable the population to increase exponentially, as opposed to the other options where the organisms are at risk for ample predation and starvation.
Exponential growth refers to the growth of organisms in an environment having unlimited resources. The organism grows exponentially or in a geometric fashion.
The dust mites living on the sofa that is often used and never cleaned.
The population has high chances of exponential growth will be:
1. Exponential growth is seen in the environment or surroundings where the resources are plentiful, and the number of organisms is dependent on those resources.
2. The dust mites living in the sofa that has never been cleaned will show exponential growth. Since the sofa is never cleaned, the mites have never faced any elimination by chemicals. The population will increase exponentially.
3. The other options have chances of competition, starvation, and predation that will not lead to the exponential growth of organisms.
Thus, the correct answer is Option A.

Water molecules have one oxygen atom in the center and two hydrogen atoms, one on each side.
what are the properties of water molecule ?It has no taste, odor, or transparency, where the nucleus of the oxygen atom attracts electrons strongly than the nuclei of the hydrogen atoms.
In water molecule oxygen is more electro negative and electron-greedy than hydrogen, results in the development of a partial negative charge on the oxygen of the water and a partial positive charge on the hydrogen end.
Water shows strong cohesive property where the attraction of molecules for other molecules of the same kind is referred to as cohesion.
Surface tension is defined as the tendency of the surface to resist rupture when they are subjected to stress due to cohesive forces.

hydrosphere
Answer:
Hydrosphere
Explanation:
When the sun impacts weather, an interaction with the hydrosphere takes place. The hydrosphere is the part of the earth that is enveloped by water. Water exists in three different forms on the earth based on diverse factors.
Weather is the atmospheric condition of a place over a short period of time.
The sun causes the warming of the earth surface which leads to evaporation of water vapor into the atmosphere.
This water in the atmosphere is forms rainfall, one of the elements of weather.
The sun causes an impact on weather by causing evaporation of water into the atmosphere.

An experiment was conducted to demonstrate the passage of glucose and starch across a selectively permeable membrane that allows monomers but not polymers to diffuse through.
Glucose and starch powders were mixed in 10 ml of water and poured into a cellulose bag, which was then sealed at both ends and placed in a beaker of water. After 30 minutes, the presence of glucose in the beaker was recorded with a testing paper, which turns green if glucose is present. The presence of starch was recorded by adding a few drops of iodine, which causes the solution to turn violet if starch is present.
A beaker filled with 100 milliliters of distilled water. A bag filled with 10 milliliters of water and a solution of 2 percent glucose and 2 percent starch is placed in the beaker of water.
Which statement best describes the expected result?
A) The testing paper will turn green and the solution will turn violet.
B) The testing paper will turn green and the solution will not turn violet.
C) The testing paper will not turn green and the solution will turn violet.
D) The testing paper will not turn green and the solution will not turn violet.
Answer:
B
Explanation:
because if you read the first paragraph, the membrane will only allow monomers not polymers. glucose is a monomer and starch is a polymer. so the membrane will only take glucose and the color for glucose therefore the color is only green.
In soreflies (a hypothetical insect), the dominant allele, L, is responsible for resistance to a common insecticide called Loritol. Another dominant allele, M, is responsible for the ability of soreflies to sing like birds. A true-breeding mute, Loritol-resistant sorefly was mated to a true-breeding singing, Loritolsensitive sorefly, and the singing, Loritol-resistant female progeny were testcrossed with true-breeding wild-type (i.e., mute, Loritol-sensitive) males. Of the 400 total progeny produced, 119 were mute and Loritol-resistant, 114 could sing and were Loritol-sensitive, 81 could sing and were Loritol-resistant, and 86 were mute and Loritol-sensitive.
