Answer:
Progesterone is one of the female sex hormones which performs important function during menstrual cycle, pregnancy and embryo development.
During follicular phase, it helps in the ovulation while during luteal phase it plays an important function of preparing the endometrium lining of the uterus. In addition, it also inhibits or decreases the production of FSH and LH during this phase with the help of negative feedback mechanism.
Progesterone gives negative feedback to hypothalamus and anterior pituitary which decreases or inhibits the secretion of FSH and LH. It is important as it prevents the ovulation of second egg prior to fertilization.
Answer:
The correct answer to fill in the blank is: transformation.
Explanation:
Transformation is a process that happens to a) cells when they change their phenotypes due to new genetic material, or b) cultured cells that keep having spontaneous phenotypic alterations due to the changes in their DNA.
Transformation can occur because spontaneously, or because of an infection with a transforming virus, gene transfection, exposure to chemical carcinogens or exposure to ionizing radiations.
Answer:
<u>Part A</u>
Drag these words to the space
(1) tRNA: "contains an anticodon" "has amino acids covalently attached in active form"
(2) mRNA: "has introns and exons" "contains genes for a protein"
(3) rRNA: "is found in ribosomes" "is the most abundant form of RNA"
<u>Part B</u>
(1) Replication: Leave blank because no RNA is involved
.
(2) Transcription/RNA processing: mRNA because it is synthesized from the information in DNA
(3) Translation: rRNA and tRNA
Answer:
<em>The correct option is A) computer simulation</em>
Explanation:
Models can be described as as a representation of ideas, events or processes. Models might be mathematical, graphical, visual or computer simulations depending on the type of event being represented.
For studying the motion of clods, a computer simulation will be best because it will make it easier to understand the events related to moving clouds during thunderstorms.
An equation, map or graph cannot be used because neither of them can depict the information for motion of clouds in the atmosphere during a thunderstorm.
I believe the correct answer from the choices listed above is option B. It would be the respiratory and circulatory systems that <span>work together to get cells the nutrients they need to carry out cellular respiration. They are responsible in providing oxygen and other nutrients throughout the body.</span>
