Explain the self-correcting nature of science.
The notion of a self-correcting science is based on the naive model of science as an objective process that incorporates new information and updates beliefs about the world depending on the available evidence. When new information suggests that old beliefs are false, the old beliefs are replaced by new beliefs.

The function of the placental hormone human placental lactogen (hPL) is to ________. Question 12 options: prepare the breasts for lactation nourish the placenta regulate the menstrual cycle help the placenta to mature All of the above are true.
Answer:
nourish the placenta
Explanation:
The hormone called human placental lactogen (hPL) is a hormone secreted by the placenta, which functions to supply nutrients and oxygen to the growing fetus in the womb.
The human placental lactogen is produced to help in the efficient use of ingested food substances in the production of energy (metabolism). This indirectly helps to nourish the placenta because if the mother efficiently converts food into nutrients, the placenta is also adequately nourished.
The phenomenon of single or double fertilization is unique to the seed plants
Answer:
Double fertilization
Explanation:
The phenomenon of double fertilization is unique to flowering plants (i.e., angiosperms). Each pollen grain produces two male gametes (sperm cells), one of which fertilizes the egg to form the zygote, whereas the other sperm fuses with polar nuclei in the female gametophyte in order to form a triploid cell (3n) called endosperm. Subsequently, this endosperm will support embryonic growth by supplying storage nutrients and by serving as a mechanical barrier during seed development and germination.

Question 7(Multiple Choice Worth 4 points)
(01.03 MC)
The evolution from vesicles to true cells was enabled by the development of
A) a membrane separating the cell from its environment
organic molecules, such as carbohydrates and lipids
B) self-replicating molecules, such as RNA and DNA
Thing
C) inorganic molecules, such as nitrogen and oxygen
Answer: The correct option is B (self-replicating molecules, such as RNA and DNA)
Explanation:
The current theory of the process of evolution makes use of present day knowledge of genes and chromosomes to explain the source of genetic variation upon which natural selection works. These genes are discrete units of inheritance which determine hereditary characteristics. All the information for the inheritable characteristics of an individual are contained in these genes.
When a cell divides, the genes duplicate themselves so that each daughter cell has an identical set of genes as the original parent cell. These genes are passed from parents to offspring in the gametes of the parents.
Gene are found in the DNA( Deoxyribonucleic acid) molecules or RNA (Ribonucleic acid) molecules. These molecules are capable of self replication due to a process called mutation. Mutations are random changes in DNA that alter genetic information and sin introduce new characteristics. They may occur
--> in body cells or
--> during gamete formation.
Thus, evolution from vesicles to true cells is through self replicating molecules through the process of mutation which is the raw material for evolution
Answer:
B (self replicating molecules such as RNA and DNA)

A 53 year old man presents with increasing gastric pain and is found to have a 3 cm mass located in the anterior wall of his stomach. This mass is resected and histologic examination reveals a tumor composed of cells having elongated, spindle-shaped nuclei. The tumor does not connect to the overlying gastric epithelium and is instead found only in the wall of the stomach. The tumor cells stain positively with CD117, but negatively with both desmin and S-100. Special studies find that these tumor cells have abnormalities of the KIT gene. Which of the following is the most likely diagnosis?
a. Lymphoma of mucosa-associated lymphoid tissue (MALToma)
b. Ectopic islet cell adenoma (VIPoma)
c. Gastrointestinal stromal tumor (GIST)
d. Submucosal leiomyoma ("fibroid tumor")
e. Nonchromaffin paraganglioma (chemodectoma)
Answer:
The correct answer is c. Gastrointestinal stromal tumor (GIST)
Explanation:
Gastrointestinal stromal tumors (GIST) are rare neoplasms that originate from mesenchymal cells, generally express the KIT receptor (CD117) and present activated mutations of the tyrosine kinase or tyrosine kinase receptor proto-oncogene, cKIT (it is the gene that encodes KIT protein synthesis). GISTs can be located in any portion of the wall of the GI tract, but most are located in the submucosa or in the muscularis propria. Some are predominantly extramural; large ones can infiltrate neighboring organs
A gastrointestinal stromal tumor (GIST) is the most likely diagnosis (Option C).
Cancer is a multifactorial disease in which cancer cells divide and proliferate to produce a tumor.Cancer is often associated with mutations in key genes which are required for the normal functioning of a given tissue (e.g. cell cycle genes).A gastrointestinal stromal tumor (GIST) is a tumor in which cells of the stomach proliferate in an uncontrolled manner.In conclusion, a gastrointestinal stromal tumor (GIST) is the most likely diagnosis (Option C).

Sponges (phylum: Porifera) are animals that possess feeding cells called collar cells. These cells have a central flagellum surrounded by a collar of microvilli. The collar filters organic matter out of the water column. Which protist shares a more recent common ancestor with the poriferans
Answer: Choanoflagellates
Explanation:
Protists are organisms that have both plant and animal like characteristics. Some protists develop more plant like characteristics and others more animal like characteristics. Choanoflagellates are the protists which looks like animals called sponges. These protists are single celled organisms. Their function is similar to collar cells of the sponges that is they produce current in water that draws water and food particles via the body of sponges and they filter the food particles through their microvilli.
explain how the mammalian skin perform it's role as a thermoregulatory
Answer:
The skin contains many blood capillaries and sweat glands ,the sweat glands secrete sweat when it is hot.when the sweat evaporates from the skin it cools the body.thermoregulation by the skin occurs through dilation and constriction of the blood vessels.when the bodies temperature raises,the blood vessels carry heat in the blood to the skin.the blood capillaries dilate become wider so that more heat can be lost to the environment.this is called vasodilation.when the outside temperature is low,the blood capillaries constrict become narrower so that less blood flows to the surface of the skin.therefore less heat is lost to the environment this is called vasoconstriction.

Answer:
A tall plant is crossed with a short plant, and the progeny are all intermediate in size between the two parental plants. If the intermediate F1 progeny were allowed to self-pollinate, and the F2 progeny were also intermediate in size, but following a normal distribution, this would suggest polygenic inheritance.
Explanation:
Two or more genes contribute to the determination of a certain trait in polygenic inheritance.
What is polygenic inheritance?When a tall plant and a short plant are crossed, all the offspring fall between the two parents plants in terms of height.
It would indicate polygenic inheritance if the intermediate F1 progeny were permitted to self-pollinate and the F2 progeny had intermediate sizes and followed a normal distribution.
Consequently, one personality trait is managed through is controlled by at least two other genes, at least two additional genes.
Therefore, If the intermediate F1 progeny were allowed to self-pollinate, and the F2 progeny were also intermediate in size, but following a normal distribution, indicate polygenic inheritance.
