iv. These molecules give the body immunity
v. These molecules flag pathogens for destruction
Therefore options I, II, IV, and V.
The characteristics of antibodiesAntibodies are the proteins of the immune system that helps in the immune response of the body against invading microorganisms.
The characteristics of antibodies include:
Antibodies are produced by special white blood cells called the B lymphocytes.When antigens of viruses are introduced into the body through the vaccine, it causes the body to produce memory antibodies.The production of antibodies by the memory B cells helps to give the body immunity.Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen.Learn more about antibodies here:

Which statement would be used in an argument against the use of human embryonic stem cells for therapy?
O Obtaining embryonic stem cells for use in therapy requires the destruction of embryos.
O Embryonic stem cells are limited in their ability to become different types of cells.
O It is difficult to grow embryonic stem cells in laboratory cultures, so they are not a practical choice for stem cell therapy.
O Embryonic stem cells originate in plants, so the likelihood of rejection by a patient's body is high.
The statement 'obtaining embryonic stem cells for use in therapy requires the destruction of embryos' would be used in an argument against the use of human embryonic stem cells for therapy. It is a type of stem cell therapy.
What are embryonic stem cells?The embryonic stem cells are cells obtained from embryos that have the property to divide and specialize into different tissues.
The embryonic stem cells can be differentiated in the laboratory for the development of specific cell lineages.
The therapy using embryonic stem cells involves the use of these types of cells and the destruction of an embryo.

Que características poseen los babuinos que no poseen los Lemures
Answer:
Opposing thumbs, expressive faces, complex social systems: it's hard to miss the similarities between apes and humans. Now a new study with a troop of zoo baboons and lots of peanuts shows that a less obvious trait -- the ability to understand numbers -- also is shared by humans and their primate cousins.
"The human capacity for complex symbolic math is clearly unique to our species," says co-author Jessica Cantlon, assistant professor of brain and cognitive sciences at the University of Rochester. "But where did this numeric prowess come from? In this study we've shown that non-human primates also possess basic quantitative abilities. In fact, non-human primates can be as accurate at discriminating between different quantities as a human child."
"This tells us that non-human primates have in common with humans a fundamental ability to make approximate quantity judgments," says Cantlon. "Humans build on this talent by learning number words and developing a linguistic system of numbers, but in the absence of language and counting, complex math abilities do still exist."
Cantlon, her research assistant Allison Barnard, postdoctoral fellow Kelly Hughes, and other colleagues at the University of Rochester and the Seneca Park Zoo in Rochester, N.Y., reported their findings online May 2 in the open-access journal Frontiers in Comparative Psychology. The study tracked eight olive baboons, ages 4 to 14, in 54 separate trials of guess-which-cup-has-the-most-treats. Researchers placed one to eight peanuts into each of two cups, varying the numbers in each container. The baboons received all the peanuts in the cup they chose, whether it was the cup with the most goodies or not. The baboons guessed the larger quantity roughly 75 percent of the time on easy pairs when the relative difference between the quantities was large, for example two versus seven. But when the ratios were more difficult to discriminate, say six versus seven, their accuracy fell to 55 percent.
That pattern, argue the authors, helps to resolve a standing question about how animals understand quantity. Scientists have speculated that animals may use two different systems for evaluating numbers: one based on keeping track of discrete objects -- a skill known to be limited to about three items at a time -- and a second approach based on comparing the approximate differences between counts.

Write half a page about why ATP is considered the energy-producing molecule and not GTP, CTP, or TTP
Answer:
Over the years, many proteins have specialized with a specific shape, and this chance is the primary reason behind ATP over GTP. In other words, the choice of ATP over GTP is primarily down to cellular preference of molecular shape. One of them had to emerge as being more widely used, and it was ATP that 'won'.

Indicate whether the following conditions require higher or lower energy needs. B. Bronchopulmonary dysplasia - Pediatric AIDs - Prader-Willi syndrome - Cystic fibrosis - Down syndrome - Spina bifida A. Lower B. Higher C. The same
The conditions requiring higher and lower energy are as listed below:
Conditions Energy Requirements
Bronchopulmonary dysplasia Higher ( B )
Pediatric AIDS Higher ( B )
Prader-Willi syndrome Lower ( A )
Cystic Fibrosis Higher ( B )
Down syndrome Lower ( A )
Spina bifida The same ( C )
Infant health conditions
Children suffering from various health conditions require a different level of energy intake from the consumption of food and this depends on the health danger the diseases posses to the body such as metabolic rate of the body.
Certain health conditions require high energy intake while certain health conditions require a lower energy intake such as ( Down syndrome and Prader-Willi syndrome ).
Hence we can conclude that the energy needs of each condition is as listed above.
