state one adaptation of nephron in the kidney of a desert mammal
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.

relationship with friends?
Ten
Fourteen
Eighteen
Late twenties
Answer:
Somewhere in the Fourteen-ish and Eighteen-ish, that's just my opinion of this matter.
Eighteen is the perfect age does a person to begin to think about education and career goals over relationships with friends.
What does adulthood teach us?Being an adult means being responsible for yourself. So instead of doing everything you want to do, you start to compromise. You learned that you need to take care of your problems instead of running away from them. Instead of pulling out an all-nighter, you learn to manage your time better.
After the eighteenth of a person, a person should be considered an adult. Adulthood is a stage where a person considers themselves more responsible for their lives and carrier goals.

Why are terrestrial planets closest to the Sun?
Answer:
The Sun sent out energy and particles in a steady stream, called stellar winds. These winds proved so strong that they blew off mostthe gases of the four planets closest to the Sun, leaving them smaller, with only their rocks and metals intact. That's why they are called rocky, or terrestrial, planets.
In Respiration, to where is the energy from sugar molecules transferred?

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
Use evidence from the Grants’ research to explain how natural selection leads to evolution. (10 points)
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.

1. How many layers are there in an arthropod's exoskeleton? What is the main function of
each layer?
Explanation:
The exoskeleton and molting
The success of arthropods derives in large part from the evolution of their unique, nonliving, organic, jointed exoskeleton (see figure), which not only functions in support but also provides protection and, with the muscle system, contributes to efficient locomotion. The exoskeleton is composed of a thin, outer protein layer, the epicuticle, and a thick, inner, chitin–protein layer, the procuticle. In most terrestrial arthropods, such as insects and spiders, the epicuticle contains waxes that aid in reducing evaporative water loss. The procuticle consists of an outer exocuticle and an inner endocuticle. In the exocuticle there is cross-bonding of the chitin–protein chains (tanning), which provides additional strength to the skeletal material. The hardness of various parts of the exoskeleton in different arthropods is related to the thickness and degree of tanning of the exocuticle. In crustaceans, additional rigidity is achieved by having the exoskeleton impregnated with varying amounts of calcium carbonate.

The formation of an exoskeleton required the simultaneous solution of two functional problems in the evolution of arthropods: If the animal is encased in a rigid covering, how can it grow and how can it move? The problem of growth is solved in arthropods by molting, or ecdysis, the periodic shedding of the old exoskeleton. The underlying cells release enzymes that digest the base of the old exoskeleton (much of the endocuticle) and then secrete a new exoskeleton beneath the old one. At the time of actual shedding, the old skeleton splits along specific lines characteristic of the group, and the animal pulls out of the old skeleton as from a suit of clothes. The old skeleton is usually abandoned but in some species is eaten. The new exoskeleton, which is soft and flexible, is then stretched by localized, elevated blood pressure augmented by the intake of water or air. Hardening occurs by stretching and especially by tanning within a number of hours of molting. In crustaceans, calcium carbonate is deposited into the new procuticle. (Soft-shell crabs are simply newly molted crabs.) Additional endocuticle may be added to the exoskeleton for some days or weeks following molting.

Molting is under hormonal control, and there is a long preparatory phase that precedes the process. The steroid hormone ecdysone, secreted by specific endocrine centres and circulated in the blood, is the direct initiator of molting. The actual timing of a molt, however, is regulated by other hormones and commonly by environmental factors. The interval between molts is called an instar. Because of the frequency of molts, instars are short early in life but grow longer with increasing age. Some arthropods, such as most spiders and insects, stop molting when they reach sexual maturity; others, like lobsters and crabs, molt throughout their lives. Most of the larger spiders of temperate regions, for example, molt about 10 times before reaching sexual maturity. As a result of molting, the length and volume of an arthropod display steplike increases over the life span, but internal tissue growth is continual as in other animals.
Loss of a limb is a common hazard in the life of many arthropods. Indeed, some arthropods, such as crabs, are capable of amputating an appendage if it is seized by a predator. The limb is then regenerated from a small, nipplelike rudiment formed at the site of the lost limb. The new limb develops beneath the old exoskeleton during the premolt period and then appears when the animal molts.

The notochord is an embryonic structure in humans that develops into
the spinal cord in the adult. What does the notochord suggest about
humans' relatedness to other species?
M
Answer:
In anatomy, the notochord is a flexible rod formed of a material similar to cartilage. If a species has a notochord at any stage of its life cycle, it is, by definition, a chordate. The notochord lies along the anteroposterior ("front to back") axis, is usually closer to the dorsal than the ventral surface of the animal, and is composed of cells derived from the mesoderm.

Answer:
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. ...

Identify and describe three mechanisms of movement of lymph through the lymphatic vessels.
Answer: Lymph fluid can only flow forward through lymphangions due to the closing of valves after fluid is pushed through by fluid accumulation, smooth muscle contraction, or skeletal muscle contraction if that makes sense. Without valves, the lymphatic system would be unable to function without a central pump.
