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

Answers

The answer is 3 3 3 3

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

Describe how oxygen is transported in blood, and explain how temperature, pH, BPG, and affect oxygen loading and unloading.

Answers

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.

Sigmoidal plots of activity versus substrate concentration are exhibited by a. holoenzymes. b. Michaelis-Menten enzymes. c. allosteric enzymes. d. monomeric enzymes. e. isozymes.

Answers

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

Answers

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.

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

Answers

it’s just because the answer is this melanin both of them have it

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.

ventilation

diffusion

Answers

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.
