Both corpus luteum and placenta secrete ______ to help ease the passage of birth and dilate the cervix.
Progesterone. It is a steroid hormone in charge of sustaining and decidualizing the endometrium.
What is a corpus luteum?
An ovary's corpus luteum is a collection of cells. During the first trimester of pregnancy, it is in charge of producing the hormone progesterone. In females, the corpus luteum is essential for establishing and maintaining pregnancy.
It is a yellow, hormone-secreting body that develops in the ovary at the site of the sac that has discharged after the egg has reached maturity during the process of ovulation. It is located in the female reproductive system. The granulosa cells that border the follicle begin to accumulate lipids and yellow pigments right after ovulation, which causes the development of lutein cells, which make up the corpus luteum.
Progesterone and estrogen are secreted by the corpus luteum. In the event of fertilization, they are crucial in creating changes in the uterus that make it more favorable for embryo-implantation; otherwise, it becomes dormant after about 14 days, resulting in menstruation.

The enzyme phosphorylase catalyzes the conversion of ___________ into ___________.
The enzyme phosphorylase catalyzes the conversion of glycogen into glucose-6-phosphate.
Glycogen is a carbohydrate storing the body of animals, including human beings. Glycogen is broken down into glucose by the enzyme phosphorylase to provide energy to the animals. The carbohydrates in the human body are stored in the form of glycogen in the liver and muscle cells of a human. It provides immediate energy while fasting by breaking down glycogen into glucose.
The breaking down of glycogen into glucose is called glycogenolysis. The hormones like glucagon and epinephrine (adrenalin) stimulate the breaking down of glycogen in the liver. Glucagon is secreted by the pancreas and epinephrine is secreted by the kidneys.
The breakdown of glycogen polymer in the liver is catalyzed by the enzyme glycogen phosphorylase to produce glucose-1-phosphate. Glucose-1-phosphate is converted into glucose-6-phosphate by the enzyme phosphoglucomutase in the liver, kidneys, and intestines. The cells of these organs secrete free glucose into the blood, thereby restoring glucose levels in the blood.

The number of modifications or mutations that have taken place in a lineage of organisms' DNA or protein sequences is represented by the frequency of a molecular clock. It can be used to determine roughly when two lineages split apart historically.
However, in highly diverse lineages, alterations could take place more more once for a specific spot (i.e., those lineages that were divided extremely far back in evolutionary time).

The ________, first proposed by francis crick, summarizes the relationships between dna, rna, and protein.
The fundamental doctrine describes the connection between DNA, RNA, and proteins and was first put forth by Francis Crick.
The fundamental tenet of molecular biology is the idea that genetic information can only move from DNA to RNA to protein or from RNA to protein directly. Cells create proteins through a process known as protein synthesis. Transcription and translation take place simultaneously. The conversion of genetic information from DNA to mRNA in the nucleus is known as transcription. Initiation, elongation, and termination are its three stages. The process of transcription involves moving genetic information from DNA to mRNA in the nucleus. Initiation, elongation, and termination are its three stages. Following processing, the mRNA transports the information to a ribosome in the cytoplasm. The ribosome, which is made up of proteins and rRNA, is where translation happens. The mRNA's instructions are read during translation, and tRNA then transports the appropriate structure of a protein to the ribosome. rRNA then facilitates the formation of links seen between amino acids, resulting in a polypeptide chain. To create the finished protein, a polypeptide chain may go through additional processing after being created.

If m∠4 = 35, find m∠2. Explain.
35; ∠2 and ∠4 are alternate interior angles, so m∠2 = m∠4.
145; ∠2 and ∠4 are supplementary angles, so m∠2 = 180 − m∠4.
55; ∠2 and ∠4 are complementary angles, so m∠2 = 90 − m∠4
35; ∠2 and ∠4 are corresponding angles, so m∠2 = m∠4.
The correct answer is option 1.
From the accompanying photo,
Right triangle CAB has three sides.
Consequently, m1 = 90°.
Similarly, mACD = 90°
∠ACD = 90° = ∠ACB + ∠BCD
= m∠3 + m∠4 = 90°
Because m4 = 35°,
m∠3 + 35° = 90°
m∠3 = 90° - 35° = 55°
In the ABC triangle,
∠ACB + ∠CBA + ∠BAC = 180° [triangle property]
∠3 + ∠2 + ∠1 = 180°
55° + ∠2 + 90° = 180°
∠2 + 145° = 180°
∠2 = 180° - 145° = 35°
Because ABCDBC is a transversal,
The lines are referred to as transversal lines when a straight line crosses two or more parallel lines. Any time this transverse line crosses a coplanar line, alternate angles—also referred to as exterior or interior alternate angles—are created.
In light of this, ∠2 = ∠4 = 35° [Alternate Interior Angles].

Your breathing must rise from about 15 times per minute (12 liters of air) at rest to between 40 and 60 times per minute (100 liters of air) during exercise in order to meet this additional demand.Additionally, your circulation quickens to ensure that the muscles have enough oxygen to continue working.The heart and lungs, two of the body's major organs, work hard while you exercise.
