Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.

Explanation:

The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.

The main features of the solar system:

The Sun is our nearest star.

The planets orbit the Sun.

The time taken to orbit the Sun increases with distance from the Sun.

Gravity keeps the planets in orbit around the Sun and the moons in orbit around their planets.

From the Sun, the order of the planets is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. You might need to be able to recall this in the exam.

The planets go around the Sun in slightly squashed circular elliptical orbits.

Pluto is classified as a dwarf planet or planetoid. It has a highly elliptical or eccentric orbit.

Main facts

The definition of a planet and a moon is fuzzy. ...

Comets and asteroids are leftovers. ...

The planets are all on the same “plane” and orbit in the same direction. ...

We're nowhere near the center of the galaxy. ...

But the Solar System is bigger than you think. ...

The Sun is hugely massive. ...

Answer:

its transferred to ATP

Explanation:

during respiration glucose and oxygen is converted into carbon dioxide and water, so the energy is transferrred to ATP

I think its c Scientists cannot determine how it changes.

d). It increases over time.

The true fact about the amount of matter in ecosystems is that it remains constant, as shown in Option b, the amount of matter in an ecosystem remains constant according to the law of conservation of matter.

An ecosystem is an interaction between living organisms and their environment, and the interactions between them are important because they provide a wide range of benefits to humans, including supporting livelihoods, providing food, purifying the air and water, regulating the climate, and also playing a vital role in maintaining the balance of nature and providing a home for a diverse range of species.

Hence, the true fact about the amount of matter in ecosystems is that it remains constant, as shown in Option b, the amount of matter in an ecosystem remains constant according to the law of conservation of matter.

Answer:

The correct answer is - Grant's research on finches on the Galapagos islands.

Explanation:

Grant's research was made on medium-sized finches on the Galapagos islands showed evolutionary processes in real-time. He showed that due to the drought there is a decrease in the number of small and soft seeds that were finches major food source.

It is known that there are different beak sizes in this finch species, the finches with larger beaks could feed on tough and large seeds and survive in such case of the drought-induced decrease in food availability. Due to this natural selection and adaption the number of larger beaks in finches is increased over the real time.
