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

Answer:

Vaporization (or vaporisation) of an element or compound is a phase transition from the liquid phase to vapor. There are two types of vaporization: evaporation and boiling.

Answer:

The two types of vaporization are evaporation and boiling.

Explanation:

Evaporation takes place at the surface of a liquid such as a puddle drying up.

Boiling takes place below  the surface of a liquid and causing bubbling like a pot of water on a hot stove.

Explanation:

Meiosis is beneficial as it produces gametes that are genetically different to the parent cell, and when the gametes combine the offspring produced is made from combination of genes from both mother and father. The offspring is genetically unique, there is no other organism on the Earth with the exact same DNA sequences on their chromosomes.

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.

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.

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 :

A brief positive current inward due to sodium entry through voltage gated sodium channels ( Option 4 )

Explanation:

What you would expect to see following the bathing of a sensory neuron in  tetra ammonium chloride and MgCl2, given that the voltage clamp moves from -70 to -5 mV is A brief positive current inward due to sodium entry through voltage gated sodium channels.

This is because as Cl^- enters the cells it causes the entrance of  Na^+ into the cell ( i.e. voltage gated Na^+ ions channels will open ) hence the mixture will cause a lower negative membrane potential to be present .

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.

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.

Thus, Milky Way is the galaxy we live in amongst others.

Answer:

Explanation:

Dispersion refers to the change in an organism's range or distribution area. Different ecological and biogeographical processes might be involved in organisms' dispersion. The term "jump dispersion" refers to a few individuals in a short time that can cross a barrier and occupy a new area. In this situation, the establishment is not always for sure. For this to happen, they must reproduce and start a new population of a certain size that can survive the new conditions.  

Biologic Invasions refer to new species that establish in a new area far or out of their original distribution range. Once established, these species might be considered exotic or invasive, according to their reproductive rate, population growth, and interaction with native species.

The exotic species is the one that has been introduced and got to establish, but causes no damage or alteration to native ecosystems.

The invasive species is introduced into a new area, establishes, expands its distribution from the first invaded spot, and overgrows. As they expand, they compete with other native species for resources such as water, place, radiation, exposure, shelter, source of food, among others. Species are considered to be invasive because of their reproductive rate, population growth, and interaction with native species, which provokes huge damages to the native ecosystem.

It is very common for these species to escape and start new populations in the new area, where they have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their establishment.

There are some typical steps in an invasion process:

1) Introduction or dispersion to the new area,

2) Naturalization. The new species establishes in the new area. It can grow, reproduce and make use of resources.

3) Overgrowth and uncontrolled expansion.  

4) Interaction with other species.  

5) Stabilization.  

Biologic invasions are natural processes, that occur in small groups of individuals that can expand to other ecosystems. Their expansion is promoted by the appearance or disappearance of barriers.  But these biological invasions have been accelerated by human beings, referring to this as human-assisted invasions. These are the cases in which men transport species from one place to the other for different uses or purposes.

Once a species has become invasive, it turns very hard to eliminate it, especially because it requires big mechanical and economical effort. However, they can be controlled to avoid their wider expansion. There are different ways of controlling invasive species

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.
