Integumentary system: it is the most extensive system of the human body since it covers it completely. Its main functions are to separate, protect, and inform our body of the environment that surrounds us. Among its many functions are: It is the first immunological barrier that protects us from the external environment; It intervenes in avoiding drying out.Excresion: Through sweating waste is excreted and body temperature is reduced.Diagnostic Role: skin can present the symptoms of many diseases, which makes it possible to diagnose them.
It is a 25% chance of both of them being heads.
Answer:
The correct answer is 88.84 mmHg.
Explanation:
The pressure differential between the brain and the heart while standing up will be 120 - rho × g (gravity) × h, here h is the distance from the brain to the heart. The h is 40 cm or 0.4 m.
rho×g×h = 1060 kg/m³×9.8 m/s²×0.4m
= 4155 Pa
Now converting Pa to mmHg we get:
4155 Pa × 760 mmHg / 1.01325 × 10⁵ Pa
= 31.16 mmHg
Thus, the pressure in the brain now is 120 - 31.16
= 88.84 mmHg (hypotension)
Answer:
Explanation:
Amphibians are group of animals that live a double life; one in water with gills and the other on land with lungs (at maturity). They include frogs, newts, salamanders etc.
Reptiles ( meaning to creep under shadow of darkness) are group of animals that possess scales. They include snakes, crocodiles, lizards etc.
Reptiles and amphibians are distantly related but share some traits including:
1. They are both poikilothermic (cold-blooded) animals i.e. their body temperature is dependent on that of the environment's.
2. They both lay eggs externally, although that of amphibians is fertilized after being layed
3. They both possess lungs for gaseous exchange, although, amphibians use gills in water.
4. Both reptiles and amphibians belongs to Chordata i.e. they both possess a vertebrae column (backbone)
5. Most reptiles and amphibians make use of the same defensive and attacking traits as a pretty and predator respectively. They employ camouflage, biting and inflating of their body size.
Forests act as habitats for wildlife, acts as carbon sinks, help reduce soil erosion, and influence local and regional climate.
<h3>Forest's ecological services</h3>
These are services that forests provide for the biotic component of the ecosystem.
Forests serve a wide variety of services to humans and animals. They act as sinks for carbon, provide habitats for wildlife, provide foods for humans and animals, protect watersheds and soils, among several other services.
Forests are also able to influence local and regional climate due to their ability to serve as sinks for carbon dioxide, a greenhouse gas capable of causing warming.
Forests, however, may not serve recreational purposes, except they are specifically modified to do such.
