Explanation:

How Does Sensory Memory Work?

During every moment of your existence, your senses are constantly taking in an enormous amount of information about what you see, feel, smell, hear, and taste. While this information is important, there is simply no way to remember each and every detail about what you experience at every moment. Instead, your sensory memory creates something of a quick "snapshot" of the world around you, allowing you to briefly focus your attention on relevant details.

Types of Sensory Memory

Experts also believe that different senses have different types of sensory memory. The different types of sensory memory have also been shown to have slightly different durations.

Iconic memory, also known as visual sensory memory, involves a very brief image. This type of sensory memory typically lasts for about one-quarter to one-half of a second.

Echoic memory, also known as auditory sensory memory, involves a very brief memory of sound a bit like an echo. This type of sensory memory can last for up to three to four seconds.

Haptic memory, also known as tactile memory, involves the very brief memory of a touch. This type of sensory memory lasts for approximately two seconds.

Answer:

C. Beak size is an inherited trait in the finch population under study.

D. Birds that could eat larger, tougher seeds survived and reproduced during the drought.

E. Beak size varies among the birds in the finch population under study.

Explanation:

The presence of genetic variations among the individuals of a population is required for natural selection to be operative. Natural selection targets the beneficial genetic variations present in the population. Natural selection refers to the differential reproductive and survival success of organisms of a population due to some beneficial genetic traits. These organisms with beneficial genetic traits are able to survive and leave more progeny under prevailing conditions.

If the natural selection has occurred in the ground finch population for the beak size, the beak size should be a genetic trait since natural selection works on genetic traits only. The finch population should have variations with respect to the beak size. The finches having the larger beak size that enabled them to feed on larger, tougher seeds should have higher survival and reproductive fitness during the drought.

Under these conditions, natural selection would favor the finches with larger beak size and would eventually result in an increase in the average beak size of the future generations.

You dilute an unknown sample of bacteria to 1 x 10-6 and plate out 10 onto a Petri dish. The next day you count 64 colonies. The
Sveta_85 [38]

Answer:

b

Explanation:

The correct answer would be 6.4 x 10^6 cells/ul.

For 1 x 10-6 dilution, the plating factor is 10^6. To find the number of bacteria in the original sample, the plating factor is multiplied by the colony count per ul.

<em>Number of viable bacteria = plating factor x colony count/ul</em>

Since 10 ul gives 64 colonies.  1 ul will give:

         64/10 = 6.4 colonies.

Therefore, the viable bacteria in the original sample = 6.4 x 10^6 cells/ul

The correct option is b.

What opposes the sliding motion of two<br> surfaces that are in contact.
sergeinik [125]

Answer:

Friction: A force that opposes the motion of objects that touch as they move past each other. Friction acts at the surface where objects are in contact.

Explanation:

The force that acts against your pushing force is called friction. is a force that resists the motion between two surfaces in contact. When you try to slide two surfaces across each other, the force of friction resists the sliding motion.

Radda [10]
The 3 can only be produced in the Mediterranean biome. This biome is known to have dry and wet weather. However, the summer seasons in this biome is very dry and usually lasts longer. Hence, the vegetation is found to be drought resistant. The 3 plants mentioned are known to be naturally drought resistant, hence it is in this biome that it thrives and survives best.
