Answer:
Menstruation, the follicular phase, ovulation and the luteal phase.
Explanation:
Menstruation, the follicular phase, ovulation and the luteal phase are the four events or phases of the menstrual cycle.

Sigmoidal plots of activity versus substrate concentration are exhibited by a. holoenzymes. b. Michaelis-Menten enzymes. c. allosteric enzymes. d. monomeric enzymes. e. isozymes.
Answer:
The correct answer is C
Explanation:
Allosteric enzyme is an enzyme that has more than one active site on the surface of the enzyme. Generally, the binding to one of these active sites affects the affinity of the other active sites on the enzyme; this causes the enzyme not to follow the Michaelis-Menten's enzyme kinetics. Thus, when the activity versus substrate is plotted on a graph, a sigmoidal curve shown instead of an hyperbolic curve (like other enzymes).

If Sarah had skin vesicles on the anterolateral region of her neck, which peripheral nerve is infected by the virus? To which peripheral nerve plexus does this nerve belong
Answer: transverse cutaneous nerve
- cervical plexus
Explanation:
The peripheral nervous system refers to the network of the motor and the sensory nerves which helps in connecting the brain and spinal cord to the entire human body. The peripheral nerves control movement, sensation, and motor coordination.
If Sarah had skin vesicles on the anterolateral region of her neck, the peripheral nerve affected is the transverse cutaneous nerve. The transverse cutaneous nerve innervates the skin which covers the anterior cervical region and it brings to the cervical plexus.

Which two physical properties of graphite make it a good mineral for use in pencils?
1. luster and fracture
2. cleavage and color
3. hardness and streak
4. greasy feel and composition
The physical properties of graphite which makes it good for pencils is ;
( 3 ) hardness and streak
Graphite is made up of carbon atoms which are held together by van der waals forces ( weak force ). They are soft and slippery which is why graphite is used in the manufacture of lubricants. while graphites are used for the manufacture of writing materials such as pencils because of its hardness and streak
Hence we can conclude that the physical properties of graphite which makes graphite good for the production of pencils are hardness and streak

write the function of eustachian tube?
Answer:
Equalized air pressure.
Explanation:
The function of eustachian tube enables air pressure to be equalized between the outside air and the middle ear cavity. The eustachian tube also known as pharyngotympanic tube that connects the middle ear cavity with the nasopharynx. Eustachian tube is responsible for the aeration of the middle ear system as well as clears mucus from the middle ear into the nasopharynx. Opening and closing functions of the eustachian tube are is very important.

Albinism is a recessive trait where an individual does not produce the pigment melanin. A man and woman who both produce melanin have one child out of three who has albinism. What are the genotypes of the man and woman
Albinism is a recessive trait where an individual does not produce the pigment melanin. Albinism is an autosomal disease where the gene which is expressed here is having albinism which is the cause of heterozygous condition.
What is the heterozygous ?
Heterozygous is the condition where the genes in the alleles are different to each other where one has a dominant character and one has a recessive character. The genotypes of the woman and man decide the genotype of the offspring.
The genotypes of the man and woman is heterozygous where the dominant once out of 3 will have the dominant traits for the albinism. The condition will have to be heterozygous as in the Ia Ii gene where the gene for the albinism will be i gene.
The same genotype for the male where the Ib i gene in which i i the albinism carrying gene here the ii condition of the gene will express the albinism.

Answer:
The Milky Way galaxy is part of a group of galaxies called the Local Group. Three characteristics that I learned about our galaxy group is The Milky Way is a large barred spiral galaxy, they come in a variety of shapes and sizes, and it appears as a milky band of light in the sky when you see it in a really dark area.
Explanation:
Edmentum
The Milky Way galaxy is a member of the Local Group of galaxies named Laniakea . The Milky Way is a massive barred spiral galaxy and can be seen as a milky band of light.
What are the characteristic feature of the Milky Way?
The Milky Way galaxy is a massive, flat, disk-shaped collection of stars, gas, and dust that spans around 100,000 light-years and is several thousand light-years thick.
The Milky Way galaxy contains every star that we can see with our unaided eyes. The Andromeda Galaxy is the only celestial object visible in the night sky with unaided eyes that is not part of the Milky Way.
It is estimated that the Milky Way is 12 billion years old.

__________________ moves the respiratory medium over the respiratory surface.
Group of answer choices
perfusion
percolation
ventilation
diffusion
Answer:
ventilation
Explanation:
Breathing, also known as ventilation, is the process of moving air or water in order to facilitate the gas exchange between the external and internal (body) environment, mostly to eliminate carbon dioxide (CO2) and bring in oxygen (O2). For example, fish are aquatic animals that need to run water over their gills to get the O2 that they need to survive (gills are organs that create a large surface area for ventilation). Moreover, insects ventilate their tracheal system to get O2. Finally, terrestrial vertebrates (i.e., amphibians, reptiles, birds, and mammals) use organs called lungs to exchange O2 and CO2 between their cells and the external environment.
Describe how oxygen is transported in blood, and explain how temperature, pH, BPG, and affect oxygen loading and unloading.
Solution :
The flow of oxygen in the blood is been transported by two ways :
1. in plasma 1.5%
2. bound to hemoglobin 98.5%
As the oxygen loads in the body, affinity of the Hb makes the oxygen loading very efficient in the blood. The Hb molecule gets saturated when all the 4 hemes are oxygen binded.
The decreased pH weakens the hemoglobin oxygen binding in the tissues.
Higher temperatures in the oxygen means a lower affinity and thus more oxygen is released and so the oxygen unloads.
Increase in the temperature, the BPG and the modification of the structure in the hemoglobin decreases the affinity for the oxygen and further enhances the unloading of the oxygen in the blood.
Flows of energy and cycles of nutrients link the biotic and abiotic components of ecosystems into a/an __________ system, ultimately structuring the feeding relationships, or __________ structure of organisms that inhabit them.
Answer:
The correct answer is - dynamic and trophic.
Explanation:

What is the role of DNA polymerase enzymes in replication?
(A) unzipping the double helix by breaking down the hydrogen bonds
(B) adding the free nucleotides to the complementary strand of DNA
(C) splitting the DNA molecule
(D)connecting the fragments on the lagging strand of DNA
Answer:
A
Explanation:
the function of DNA polymerase is to unzip the double helix structure of DNA by breaking down the weak hydrogen bond
Answer:
(B) adding the free nucleotides to the complementary strand of DNA
Explanation:
A DNA polymerase is an enzyme capable of creating new DNA molecules by sequentially adding nucleotides to the three prime (3')-end of a DNA strand. A DNA strand is a polynucleotide chain composed of a linear series of nucleotides, each consisting of a deoxyribose sugar, and phosphate, and a base (i.e., thymine, guanine, cytosine and adenine). Before a cell starts to divide, it needs first to replicate its genetic material by using DNA polymerases that duplicate the cell's DNA during the interphase (S phase). During this process (DNA replication), an enzyme known as helicase unwinds the DNA molecule, which is made up of two antiparallel strands oriented in opposite 3′-5′ directions to each other. Subsequently, each strand is used as a template for its replication through DNA polymerases that can add nucleotides (one at time) to an existing short fragment of RNA, i.e., the primer sequence, which is paired with the template DNA strand.
