Answer:
b. False
Explanation:
These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.
The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.
For a PCR reaction to be performed a solution with some components must be prepared. These components are:
- Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
- Forward and reverse primers (to customize the start of the enzyme reaction)
- DNA polymerase (Enzyme required for replication of desired DNA region.)
- DNA Template (the DNA to be copied)
- PCR-grade water
- Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).
Answer:
Option B
Explanation:
Complete question -
Following their sixteen-week, closed-ended, grief and loss psychotherapy group with adults as reported by Price et al, which of Yalom's therapeutic factors was most identifiable?
a. recapitulation
b. altruism
c. universality
d. imagery
Solutions -
Out of the eleven therapeutic factors the one that will be easily recognizable will be the one which will involve some kind of action and interaction or any visible signs. Altruism would affect a person positively and help him/her to gain confidence. This confidence will be visible by the person’s action when he/she will help other people in the group to gain value and significance in the same way as he/she has done.
Hence, option B is correct
As when things get eaten some of the energy is lost the predators have to have more than one prey to survive, this means there is only a limited amount to be shared which means less predators
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.
