Which is NOT a function of proteins?
(Choose only ONE answer.)
1)working in the immune system
2)providing energy
3)working as enzymes
4)building muscle
Answer:
1. working in the immune system.
Explanation:
Proteins are responsible for the development of hairs, skin, wool, and nails in our body. Meat, eggs, and fish are some of the rich food sources of proteins. Enzymes are proteins made up of amino acids and acts as biological catalysts in our body. However, glucose serves the purpose of energy provider for the metabolism which is not a protein.

Which of the following statements is likely to also be true of the TRAPPIST-1 planets based the characteristics of the terrestrial planets in our solar system?
Answer:
The star we today call TRAPPIST-1 was first discovered in 1999 by ... Telescope and ground-based telescopes discovered that the system ... Three of these planets are in the theoretical "habitable zone," the area around a star where rocky planets are most likely to hold liquid water. The TRAPPIST-1 system hosts seven Earth-sized, temperate exoplanets orbiting an ultra-cool dwarf star. As such, it represents a remarkable setting to study the formation and evolution of terrestrial planets that formed in the same protoplanetary disk

a _ is a push or a pull on an object
Answer:
Force
Explanation:
Answer:
A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.
Explanation:
If you looked at the mouthparts of a grasshopper, a butterfly, and a mosquito, you would see that they are very different. Grasshopper mouthparts are adapted for cutting and grinding up tough plant food; butterflies have a single, long, curled sucking tube for drinking nectar; and mosquitoes have both a sucking tube and needlelike structures for piercing skin. In spite of their differences, though, all three insects (indeed, all 900,000 species of insects!) have mouthparts composed of the same anatomical structures in the same positions. These facts tell you that
Answer:
Explanation:
This fact about the three insects shows that this insects have a common ancestor.
For the anatomical structure to be the same it means a structure or an individual who posses that anatomical structure is common to them which is the ancestor.
Although modifications has occurs, changes have abound that now give rise to different mouth structures there is still a common ground which is the anatomical structure produced by their ancestors and it is inherited and passed on to successive generations.
In the female human reproductive system, eggs are created in an ovary, and implanted in the uterus. For the embryo to grow, it must receive nutrients and oxygen. This problem is solved through an organ called the A. Amniotic sac B. Placenta C. Uterus D. Umbilical cord
Answer:
The correct answer is D. Umbilical cord
Explanation:
The umbilical cord connects the fetus to the placenta and through it exchanges nutritional substances as well as oxygen-rich blood. The umbilical cord is maintained throughout gestation until the moment of birth, when it is cut and leaves a permanent scar, the navel. The umbilical cord is responsible for breathing and feeding the fetus until the moment it is born, so any failure or blockage in the circulation of oxygen and nutrients through the cord can lead to injury or even death of the embryo. It also serves to remove waste and carbon dioxide (CO2).

explain why genetic analysis provides the most definitive indicator of relatedness among organism
Answer:
A genetic analysis is a test that aims to analyze DNA, that is, the chemical database that contains the information of the organism.The analysis of various genetic markers in the organisms studied allows to establish a paternal-filial relationship or determine if it exists some kind of shared biological ancestry
Explanation:
To carry out a genetic study, we must study the genetic material stored in our cells. A genetic study is one that includes “the study of DNA, RNA, chromosomes, proteins and certain metabolites, in order to detect genotypes, mutations, phenotypes or karyotypes. All biological kinship tests are based on obtaining and analyzing the genetic material (DNA) of the organisms to be analyzed to study their genetic markers and compare them in each organism.Genetic markers are segments of DNA located at a known position (a locus) on a certain chromosome. Genetic markers are randomly received from biological parents following the rules of simple Mendelian inheritance. The presence of a pattern of genetic markers (called alleles) different from those of their parents would indicate that they are not their biological parents. Analyzing a sufficiently high number of markers could reach a point where, using specific statistical procedures, the studied relatedness link can be confirmed or discarded.
Is a pencil a biotic or abiotic matter?
A fruit fly somatic cell contains 8 chromosomes. How many chromosomes will each fruit fly gamete contain?
Answer:
The somatic cells of fruit flies contain eight chromosomes, which means they have two sets of four chromosomes. Meiosis is the process by which sex cells are produced. Sex cells are haploid, which means they have one set of chromosomes.
Explanation:
Fruit flies have two sets of four chromosomes because their somatic cells have eight chromosomes. The process through which sex cells are created is called meiosis. The haploid nature of sexual cells means that they only have one set of chromosomes.
What is Meiosis?In sexually reproducing organisms, meiosis is a unique type of cell division of spermatids that results in the production of gametes, such as sperm or egg cells. Two rounds of division are necessary, and the end product is four cells with just one duplicate of each chromosome.
When the chromosome count in daughter cells is decreased to half that of the parent cell during meiosis, the process is known as reduction division. For instance, while a human cell has 46 chromosomes, the egg and sperm cells created by meiotic division only have 23. In the above given example, fruit flies have two sets of four chromosomes as their somatic cells have eight chromosomes.
Thus, fruit flies have two sets of four chromosomes because their somatic cells have eight chromosomes.

Explain how the reproductive strategies of mosquitoes and elephants help them overcome the natural threats of their environment
Answer:
Adult elephants have few natural predators. However, baby elephants are too small to defend themselves from predators. Therefore, adults protect their young through herding and by raising them until they are strong enough to survive on their own. Mosquitoes produce a large number of offspring to make up for their short life span and the high risk of predation.

was Dr. Gey's use of Henrietta Lacks' cells unethical? Support
your response with evidence from all three sources,
For the source material please read the Radiolab segment, as well as the two articles on Dr. Gey's use of Henrietta Lack's cells from the biomedical test chapter 3.
Answer:
Dr. Gey's use of Henrietta Lack's cells after 24 years was not unethical due to his effort to figure out what was wrong with cells and why it happened to Henrietta.
Even if he did his intentions were to figure out how to treat cancer and help many people from the lethal condition. His effort made it possible to grown immortal human cells in culture. That help in developing the polio vaccine, and many other milestones.
