E. coli Is a species of bacteria that causes many different Infections in humans. Certain E. coli strains have developed resistance to antibiotics,
making Infections with these strains difficult to treat. How do bacteria such as E. coll, which reproduce asexually, galn new tralts such as
antibiotic resistance?
O A. by adapting to changes in environmental conditions without undergoing changes in their DNA
OB. by mutating their DNA in response to environmental conditions to gain beneficial traits
OC. by undergoing spontaneous mutations when they replicate, which increases genetic variation in a population
OD. by producing offspring with new gene assortments from genetic recombination, which increases diversity in a population
Answer:
The correct answer would be B
Explanation:
Antibiotic resistance in bacteria develops in response to the environment in which the bacteria survives.
The antimicrobial resistance trait is acquired by any species of bacteria through one of the two ways that are either by making changes in their DNA sequences or through horizontal gene transfer mechanisms.
In the given E. coli gained the trait to develop resistance against antibiotic by making changes in their DNA as once the gene is altered or mutated, the trait can be passed on to the offsprings.
Therefore, Option-B is the correct answer.
Answer:
B. By mutating their DNA in response to environmental conditions to gain beneficial traits
Explanation:
Through the process of natural selection, bacteria such as E coli can gain new traits that benefit them.
This can occur when a DNA mutation occurs, where the mutated gene is actually beneficial to respond to environmental conditions.
Then, these bacteria with the gene will survive and produce more offspring with the same gene. This is how E coli can develop antibiotic resistance.
So, B is the correct answer.

States of matter:There are three states of matter which are;
SolidLiquidGasParticle motion in the states of matter:The degree of motion of particles in the three states of matter differs. The particles of matter in a solid are compacted hence a solid has no space between particles. Particles are less compacted in the liquid phase but are very free in the gas phase.
Hence, model 1 must be the correct representation of a liquid.

A lamp that plugs into a wall socket draws energy which flows through a thin wire in the bulb causing it to glow. What energy transformation are taking place?
choices:
Chemical>light>electrical
Mechanical>sound>light
Thermal>solar>electrical
Electrical>thermal>light
Answer:
Electrical>thermal>light
Explanation:
Electrical energy refers to energy which is gotten from potential energy. This energy source could be a wall socket.
Thermal energy on the other hand refers to internal energy of a system where temperature is constant.
Light energy is made up of photons which transmits electromagnetic radiation which move in waves and become visible to human eye.
Therefore, the energy transformation taking place according to the question is option D.

Think and discuss:Suppose you are a farmer trying to grow plants in a greenhouse. Why would it be important to know what the limiting factor is
Answer:
Because limiting factors affect plant growth
Explanation:
A limiting factor is a condition that limits the population's growth in an ecosystem by slowing or stopping its growth. These factors are generated by the lack or excess of a particular resource. In plants, limiting factors include, among others, light, water, temperature, oxygen, food, (i.e., nutrients and minerals), space, etc. In this case, the farmer must know which greenhouse conditions are limiting factors in order to ensure the survival and optimal development of the plant population.

The characteristic described by the professor is most similar to the characteristic of aquatic protist - diatoms. Diatoms are the aquatic protist fall into the eukaryotic type of organisms.
These organisms are single-celled and can not swim on their own. They are a primary producer as they do not depends on others for their food and energy and synthesized themselves.
In passive transport, molecules move__ the concentration gradient.
Answer:
In passive transport, molecules move with the concentraction gradient.
Explanation:
If molecules moved against it would be active transport.
Passive transportation has been defined as the mode of molecule movement across the semi-permeable membrane. "In passive transport, molecules move down the concentration gradient."
What is passive transport?Passive transport has been the mode of movement of the ions and molecules from the exterior and interior of the cell through the plasma membrane. This mode of transportation has been characterized by the movement of the ions from the region of a higher electrochemical gradient.
The ions tend to move towards the region that lacks the electrochemical gradient, hence it is a movement in the direction of the lower concentration. The solute particles do not external source of energy to drive the movement from higher concentration areas.
It is a type of diffusion that uses the law of Thermodynamics to move the ions up and down the cell concentration. The movement of the oxygen gas in the body cells is an example of passive transportation.
Therefore, the ions move down the concentration gradient in the passive transport.
