Answer:

Mitosis and meiosis both involve duplication of a cell's dna content

The biological species concept tells us that organisms belong to the same species if they can breed to produce fertile and viable offspring. Speciation is therefore the development of reproductive isolation between individuals of an original population.

This can occur in 2 different ways:

1. Allopatric speciation. This is when speciation occurs due to some sort of geographic barrier separates a population into 2 groups. These two groups can then undergo genetic divergence, where each group grows increasingly dissimilar genetically due to random mutations and natural selection acting separately in each group, or from processes such as genetic drift. It is important to recognize that the lack of gene flow between these two groups contributes to the genetic divergence of the groups. Genetic divergence can lead to prezygotic and post-zygotic barriers which prevent production of fertile/viable offspring between the 2 groups. Each of these populations now represents a new species, whose gene pools are completely separate from one another.

2. Sympatric speciation. This is when speciation occurs without the presence of any sort of physical/geographical barriers. Truthfully, this is a much less common occurence. However, it is thought that sympatric speciation can occur as a result of strong divergent selection. Sympatric speciation may also occur as a result of a polyploid individual being introduced into a diploid population.

Isolation leads to speciation by preventing gene flow between 2 groups of an original population, allowing genetic differences between the groups to accumulate over time (via natural selection, genetic drift, etc.). Over time, the accumulation of these genetic differences may result in reproductive isolation between the 2 groups, causing these two groups to be committed to separate evolutionary paths.

Answer: So, how might speciation happen?

Explanation:

Speciation describes a situation where a population in a species becomes so different that it can no longer successfully interbreed with other populations of the ‘same’ species.

Answer: The granum is a part of the chloroplast. The chloroplast contains the chlorophyll pigment and it is necessary for the trapping of the energy present in the sunlight. As a result of this the photolysis of water takes place and hence water is broken down from water molecule to proton and oxygen.

These are the five examples for the molecules with the clear definition.

Answer:

Evolution.

Explanation:

The deep-sea vent organisms are the evidence of evolution because these organisms evolve with the passage of time and able to survive the extreme environmental condition of the deep sea vent. Evolution is the change in the characteristics of a species with the passage of several generations and relies on the process of natural selection. This evolution helps the organisms to adopt the surrounding environment and able them to survive in it.

Answer:

Primary producer = Oak tree leaves

Primary consumer = Caterpillars

Secondary consumer = Blue j a y s

Tertiary consumers = Hawk

Explanation:

An energy pyramid is a graph which shows how energy is transferred or flows from one trophic level to the next. Organisms which occupy the same level in the food chain within an ecosystem belong to the same trophic level.

The shape of an an energy pyramid is a pyramid indicating that the number of living things as well as the amount of energy flow decreases as one goes from one lower trophic level to the next higher level.

At the base of the pyramid are the primary producers which use energy of the sunlight to manufacture their own food. Example is the Oak tree.

The next higher level is the primary consumers who feed directly on the primary producers. For example caterpillars.

The next higher level is the secondary consumers who feed on the primary consumers. For example the Blue j a y s.

The highest levelin the pyramid is the tertiary consumers who feed on the secondary consumers. For example, the hawk.

Answer:

Yes humans can directly see a photon.

Explanation:

In fact, photons are the only things that humans can directly see. A photon is a bit of light. Human eyes are specifically designed to detect light.

This happens when a photon enters the eye and is absorbed by one of the rod or cone cells that cover the retina on the inner back surface of the eye.

For Example

Thus, Yes humans can directly see a photon.

The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism's DNA that create diversity within a population by introducing new alleles.

Answer: The movement of continents changes wind patterns and ocean currents.

hope this helps!

Explanation:

The best statement that describe the effect of tectonic activity on climate change is that the movement of continents changes wind patterns and ocean currents.

Tectonic activities includes volcanoes, mountain building, earthquakes and many more.

Tectonic activities are common in plate boundaries where plates converge, diverge or transform.

As a result of the movement of these continental plate, tectonic activities occurs causing earth climate change

Therefore, the movement of this oceanic or continental plates changes the wind pattern and ocean current.

Answer:

The inner ear has two openings into the middle ear, both covered by membranes

Explanation:

The oval window lies between the middle ear and the vestibule, whilst the round window separates the middle ear from the scala tympani (part of the cochlear duct)

❈ The internal ear —

➥ The inner ear (also called the labyrinth) contains 2 main structures — the cochlea, which is involved in hearing, and the vestibular system (consisting of the 3 semicircular canals, saccule and utricle), which is responsible for maintaining balance.

➥ The cochlea is filled with fluid and contains the organ of Corti — a structure that contains thousands of specialised sensory hair cells with projections called cilia. The vibrations transmitted from the middle ear cause tiny waves to form in the inner ear fluid, which make the cilia vibrate.

➥ The hair cells then convert these vibrations into nerve impulses, or signals, which are sent via the auditory nerve to the brain, where they are interpreted as sound. The round window (fenestra cochlea) is a membrane that connects the cochlea with the middle ear. It helps dampen the vibrations in the cochlea.

➥ The semicircular canals also contain fluid and hair cells, but these hair cells are responsible for detecting movement rather than sound. When you move your head, the fluid within the semicircular canals (which sit at right angles to each other) also moves. This fluid motion is detected by the hair cells, which then send nerve impulses about the position of your head and body to the brain to allow you to maintain your balance.

➥ The utricle and saccule work in a similar way to the semicircular canals, allowing you to sense your body’s position relative to gravity and make postural adjustments as required.

❈ The middle ear —

➥ The middle ear is an air-filled space that contains 3 tiny bones (known as ossicles), called the malleus (hammer), incus and stapes (stirrup). Sound waves that reach the tympanic membrane cause it to vibrate.

➥ This vibration is then transmitted to the ossicles, which amplify the sound and pass on the vibration to the oval window (a thin membrane between the middle and inner ear). The Eustachian tube is a narrow tube that connects your middle ear to the back of your nose and throat (known as the nasopharynx). Its function is to allow air into the middle ear as well as drain mucus from the middle ear into the nasopharynx.

➥ When you swallow, your Eustachian tube opens up to allow air into the middle ear, so that the air pressure on either side of the tympanic membrane is the same. In situations when there is a sudden change in air pressure (e.g. during take-off and landing when travelling on a plane), the pressure in the middle ear is not the same as the outside air pressure.

➥ This can make your eardrum bulge or retract and less able to transmit vibrations, causing temporary hearing problems. By swallowing or ‘popping’ your ears, you can equalise the pressure.

D. light energy produced in earth's geosphere

Explanation:

Earth's internal heat budget is very important to Earth's thermal history. The heat flow from the earth's interior to the surface is estimated to be 47 ± 2 terawatts (TW) and originates from two main sources

The internal source of Earth's energy that helps drive convection currents below the crust is D. light energy produced in the earth's geosphere.

Convection current refers to the current that is formed as a result of differential heating. It should be noted that lighter warm material rises while the heavier cool material sinks.

The light energy that is produced in the earth's geosphere is necessary for driving convection currents below the crust. Energy is transferred through the oceans and the geosphere by convection.
