There are several techniques used to evaluate the activity of the brain, each technique has its own mechanism. One of the most known technique with repeated scans is Computed tomography.
Computed tomography (CT) is a technique that <span>includes repeated scans to allow researchers to see the brain at work. the x-ray beams are aimed at the subject's head then sampled by one of the many detectors in the machine.</span>
Answer:
The correct answer is b) Bacteria are able to transcribe and translate human DNA. and thus, they potentially could produce human proteins.
Explanation:
Bacteria could produce human proteins, but they don't need them, so their physiological mechanism produces only the proteins and secondary metabolites needed.
Animals can be classified according to different physical characteristics, such as body covering (e.g., hair, fur, feathers, scales, shells), body shape (e.g., two main features, three main features), appendages (e.g., arms, legs, wings, fins, tails), and method of movement (e.g., walking, crawling, flying, swimming).
Answer: TT: 1/4; Tt: 2/4;tt: 1/4
Explanation:
The Punnett square is a diagram that is used in the predictions of genotypes. In this scenario, if we have a tall plant (TT) is crossed with a short plant (tt), after using the Punnett square, the genotype that we will get are as follows:.
TT, Tt, Tt, tt
Therefore, the correct option is option D "TT: 1/4; Tt: 2/4;tt: 1/4
Answer:
2
Explanation:
The bones in the forelimbs of penguins and seals are best described as analogous, while the flippers of penguins and seals are homologous.
Analogous structures are structures that are similar in different organisms, even though they are unrelated to each other. For instance, the wings of birds and the fins of a penguin or a fish.
Homologous structures are similar structures in related organisms. Both the penguins and the seals have flippers. Another example is the human arm and the wings of a bat. Both have similar structures internally, but while a human lifts items with their hands, the birds use theirs for flying.
