Explanation:

After the fertilisation the genotype will be : 3 Ff, 1 FF . So the phenotype will be : 3 Flar fingernails and 1 round fingernail . 3÷4 × 100= 75&

Answer:

sediment

Explanation:

debris is trash

lava is hot magma that is on the earth's surface

magma is in the earth's surface

sediment would be considered the sand and small particles.

Explanation:

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:

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.

A human heart is roughly the size of a large fist.

Explanation:

but the size varies according to an individual's age, health and size. The heart weighs 7 to 15 ounces.

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.

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.

Herbívoro: 30000 y productor: 300000.

Explicación:

Si un carnívoro requiere 3000 calorías por día, el carnívoro se comerá al herbívoro que tiene 30000 cantidad de energía y el herbívoro come 300000 cantidad de energía de las plantas porque de productor a herbívoro y de herbívoro a carnívoro, solo el 10 por ciento de la energía se transfiere mientras que el El 90 por ciento restante se libera en la atmósfera en forma de energía térmica, por lo que al usar la regla del 10 por ciento, el herbívoro come plantas en grandes cantidades y el carnívoro come herbívoros.

The carrying capacity for an animal would increase.

Animals are often used by travellers or farmers to carry different types of loads. Such animals include the donkey, buffalo, oxen, elephant, horse, camel and yak.

Such animals derive energy from already produced foods which is required by their body to support the heavy loads carried by them.

When the food or resources available increases the carrying capacity of these animals are expected to increase because more energy is being made available.

Explanation:

Answer:

Both depends on different factors.

Explanation:

The rate of movement of the air bubble is not exactly the same as the rate of water loss from the plant because both depends on different environmental factors. The higher rate of movement of the air bubble occurs due to removal of pressure while on the other hand, the rate of water loss from the plant occurs due to temperature. So both air bubble and transpiration process depends on different environmental factors.

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.
