Answer 2

Answer:

(a)

Protoplanets are built up through the collisions of planetesimals over millions of years. The protoplanets orbit stably around the Sun for a while, but eventually they collide with each other. In about 100 million years, several terrestrial planets, like the ones found in our Solar System, are formed.

At a deep sea whale fall, the Atlantic hagfish, the crustaceans, and the sand make up which of the following?

Answers

Answer:

I would say part of an ecosystem and community.

Explanation:

An ecosystem is a biological community of interacting organisms and their physical environment .In the bottom of the sea,there are already many animals living here and when the whale fall appears at the bottom of the ocean it becomes apart of the ecosystem as it provides them with food.

This is because when a whale dies, its body often falls to the seafloor. The whale's body then becomes food and shelter for organisms in the deep sea. This is called a whale fall. A deep-sea whale  fall might support 200 different species for as long as 10 years! Larger species, such as Atlantic hagfish, are the first to arrive to feed  on the whale flesh. Later, smaller species of snails and crustaceans come to eat the remaining flesh. Worms burrow into the sand beneath  the whale body, and bacteria feed on the whale bones.

Answer:

Part of an ecosystem

Explanation:

The Atlantic hagfish and the crustaceans are living organisms. The sand is a nonliving part of the environment. An ecosystem is made up of living organisms and the nonliving parts of their environment. So, the Atlantic hagfish, the crustaceans, and the sand make up part of an ecosystem.


18. Which tool of the biologist is more suitable for culturing bacteria in the
laboratory?
A. Test tubes
C. Perti dishes
B. Microscopes
D. Beakers​

Answers

Answer:

I think C. Petri dishes

Explanation:

"The most common growth media nutrient broths (liquid nutrient medium) or LB medium (Lysogeny Broth) are liquid. These are often mixed with agar and poured into Petri dishes to solidify. These agar plates provide a solid medium on which microbes may be cultured."-https://courses.lumenlearning.com/boundless-microbiology/chapter/culturing-bacteria/

The human eye is filled with a clear fluid called the aqueous humor. The production, flow, and drainage of this fluid is an active and continuous process which keeps the healthy eye at an intraocular pressure of about 15 mmHg. If the drainage becomes obstructed, fluid accumulates in the eye resulting in an increase of this pressure to the 25 to 50 mmHg range and the clinical onset of glaucoma. What is the pressure of 30 mmHg expressed in units of psi (pounds per square inch)

Answers

Answer:

The pressure will be "0.579 psi".

Explanation:

The given value is:

Hg,

= 30 mm

Density of mercury (Pm),

= 13600 kg/m³

As we know,

1 psi = 6895 N/m²

Now,

The pressure will be:

=  [tex]30 \ mm \ of \ Hg[/tex]

=  [tex]30\times 10^{-3}\times Pm\times g[/tex]

On substituting the given values, we get

=  [tex]30\times 10^{-3}\times 13600\times 9.8[/tex]

=  [tex]3,998,400\times 10^{-3}[/tex]

=  [tex]3,998.4 \ N/m^2[/tex]

So,

The pressure of 30 mm of Hg will be:

=  [tex]\frac{3,998.4}{6895}[/tex]

=  [tex]0.579 \ psi[/tex]

X-rays _____.
are blocked by the ionosphere
are less dangerous than ultraviolet rays
have very long wavelengths
are not emitted by the sun

Answers

Answer:

have very long wavelengths

Explanation:

The first  X-ray image was captured by Wilhelm Conrad Roentgen (1895), who accidentally discovered these rays while experimenting with vacuum tubes. X-rays are high-energy electromagnetic radiation with very long wavelengths (in the range of 0.01 to 10 nanometers, nm). They are shorter in wavelength than ultraviolet rays and longer than gamma rays. X-rays have energies ranging from 100 electron-volts (eVs) to 100 kiloelectron-volts (keVs). On the other hand, the radio waves are blocked by the planet's ionosphere and, therefore, they cannot reach the Earth.

You are a physiologist on a space flight to a distant planet. You discover intelligent human-like aliens on the planet. You discover that the alien's kidney handles the sugar alcohol mannitol just like our kidneys handle inulin. The data from that experiment are: Plasma level (constant over 24 hrs): 6 g/dL of mannitol 24 hr. urine sample: volume of 2 L, containing 144 g mannitol What is the alien's glomerular filtration rate (in units of ml/min)

Answers

Answer:

1.67 ml/min

Explanation:

Glomerular filtration rate (GFR) is the best overall index of kidney function, which determines the amount of blood that passes through the glomeruli each minute. Human kidneys can filter the inulin, but they cannot reabsorb or secrete this polysaccharide, thereby it is an excellent substance to measure the Glomerular filtration rate (GFR) by measuring its excretion from the kidneys. In this case, alien´s Glomerular filtration rate (GFR) can be calculated as the excretion rate of mannitol/plasma mannitol level >>>

GFR = 144 g/1 day x 1 dL/6 g x 0.1 L/1 dL = 2.4 L/1 day

GFR = 2,400 ml/1,440 min = 1.67 ml/min

photosynthesis, respiration, volcanic eruption, decomposition

Answers

Answer:

-> photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

-> respiration: a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

-> volcanic eruption: Volcanic eruptions happen when lava and gas are discharged from a volcanic. Volcanic eruptions often cause temporary food shortages and volcanic ash landslides called Lahar. The most dangerous type of volcanic eruption is referred to as a 'glowing avalanche'.

-> decomposition: Dead organisms are broken down into smaller pieces by the process of decay.

Explanation:

Hope you get your answer correct!

Have a good day :D

Answer:

Photosynthesis: Photosynthesis is the process by which plants convert light energy to starch and chemical energy to manufacture their own food.

Respiration: Respiration is the process by which a living thing breathes in air. humans breathe in oxygen and breath out carbon dioxide, on the other hand plants breathe in carbon dioxide and breathe out oxygen.

Volcanic Eruption: Volcanic eruption is the process when a volcano sends out lava to the outer surface of the earth due to tectonic plate movements.

Decomposition: Decomposition is the process by which dead organic substances or decaying matters are broken down into simpler organic or inorganic matters with the help of natural processes.

Complete question:

If an increase in dicynodont species diversity (in other words, number of species) occurred soon after the Permian extinction, and if it occurred for the same general reason usually given for the increase in mammalian diversity following the Cretaceous extinction, then it should be attributed to

A) an innovation among the dicynodonts that allowed them to fill brand-new niches.    

B) the availability of previously occupied niches.

C) the extinction of the dinosaurs (except the birds).

D) their out-competition of many other terrestrial organisms.

Answer:

B) the availability of previously occupied niches.

Explanation:              

Some species could survive massive extinctions caused by severe natural catastrophes. Some of them were small animals that could hide in certain places that were useful for their protection during the catastrophe. Those animals, that for instance, could hide underground, were able to avoid extreme temperatures and highly toxic gas concentrations caused by the phenomenon. Catastrophes caused severe damage to the Earth´s surface, causing the extinction of many other animal and vegetal species, causing changes in the morphology of the ground, and in temperature. Animals that could survive found themselves in a whole different place. Many niches were now available to be re-occupied. Survivers could specialize in different feeding strategies,  finding new different shelters, and developing new morphological characteristics that lead to a rapid diversification and speciation.

You literally trust braking systems with your life every time you get into a vehicle or cross a busy intersection, but how does this process work? It begins when the pedal is pushed. At this moment brake fluid is released into the area where the braking mechanisms are located. As the fluid collects, leverage is created, which causes a friction to be applied. If the braking system is functioning properly, this friction will create a force that will cause the wheels to stop and allow you to reach your destination safely.
