1)working in the immune system
2)providing energy
3)working as enzymes
4)building muscle

Answers

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.

Explanation:

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

Answers

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).

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.

A fruit fly somatic cell contains 8 chromosomes. How many chromosomes will each fruit fly gamete contain?

Answers

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.

Answer:

a. Recall and master the procedure in using a salinometer

Explanation:

Salinometer, which is also known as salimeter is a laboratory equipment used to measure the salinity of a solution. Salinity refers to the concentration/amount of salt in a solution.

According to this question, a student was instructed by his/her teacher to measure the salinity of brine used in curing fish. This means that to do this, the student will have to make use of a SALINOMETER. In order to use the salinometer, the student has to recall and master the procedure in using a salinometer.

Suppose if all the bones of the skull (facial bones) are fused together, which function would you not be able to carry out?

Answers

Answer:

to masticate food

Explanation:

In adults, all the bones of the skull, except one, are fused together by immovable joints referred to as sutures. The sutures are fibrous joints which hold the bones of the skull together to form a rigid and strong structure that protects the brain. Skull bones fuse around two-years (18 to 24 months after birth). The only skull bone that is not fused by sutures in adults is the mandible, which is used to masticate food.

The evolution of the peppered moth over the last two hundred years has been studied in detail. Originally, the vast majority of peppered moths had light colouration, which effectively camouflaged them against the light-coloured trees and lichens upon which they rested. However, due to widespread pollution during the Industrial Revolution in England, many of the lichens died out, and the trees which peppered moths rested on became blackened by soot, causing most of the light- coloured moths to die off due to predation. At the same time, the dark-coloured moths flourished because of their ability to hide on the darkened trees. Since then, with improved environmental standards, light-colored peppered moths have again become common, but the dramatic change in the peppered moth's population has remained a subject of much interest and study Which type of selection is illustrated by the peppered moth's during the Industrial Revolution?

Answers

Answer:

Directional selection

Explanation:

The phenotype of individuals and the environment where they live, interact and determines the genes´ destiny in space and time. The result of this interaction and the gene destiny is Natural Selection. Natural selection selects beneficial alleles and increases their frequency in the population.

Among the different types of natural selection, we can find "directional selection".    

Directional selection increases in the proportion of individuals with an extreme phenotypic trait, in this case, dark moths color. This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.

In the exposed example, the moth population must be adapted to its environment. The coloration is related to survival strategies. In the beginning, they expressed light coloration useful to camouflage and to avoid predators while resting on their lighted-substrate (lichens and light-colored trees). After the severe environmental impact of the Industrial Revolution, the environment changed. This change acted as a selective pressure. Lichens died, and trees became darker. Light moths were exposed and died after predation. Probably at one point of the evolution, the gene for color mutated, and dark-colored moths appeared. By natural selection, the mutation got fixed. This example reflects directional selection because the population turned from light color to dark color.

In the attached files you will find two graphs expressing directional selection.
