Answer:
Reduces heat lost to the water
Explanation:
In some birds such as the geese, to reduce the amount of energy cost when regulation their temperature, some morphological and behavioural has been used to maintain the rate of heat gain and loss. For uninsulated parts of the birds's body such as the legs, there is the presence to countercurrent head exchange between wherein the arteries and veins in the legs lie in close contact with each other in other to retain heat as these uninstalled regions are potential areas of heat loss since they are uninsulated unlike insulated parts (parts covered with feathers). Constriction of the arteries and veins will ensure blood flow to the feet of the geese at a low temperature.
Answer:
C. Individuals with thicker fur had a survival advantage in the cold, allowing these individuals to reproduce moe often and create more offspring.
Explanation:
Natural selection means the process of changing the adapting the new environment. Based on the given data one can conclude that the individual with thicker fur had a survival advantage in the cold environment.
Why natural selection occurs?
Natural selection takes place due to 3 underlying reasons:
Reproduction
Heredity
Variation in fitness of organisms.
Due to these reasons, natural selection can leads to speciation.
As the individual are living in cold environment, they need to adapt the change in environment. So, individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offsprings.
Thus, option C is correct.
Answer:
Well a living thing is defined as in a scientific term, the ability to reproduce. Living things like humans, animal and even plants are considered living because we can reproduce, even plants by making new seeds in the plant growth process. Non living things are things that won’t be able to reproduce, like for example a rock can t reproduce since it’s not living and it just “lacks the abitlity to”.
Answer:
Hi, there your answer is A. Genes
Explanation:
Answer:
The superior vena cava is formed by the merging of the right and left brachiocephalic veins.
Explanation:
The superior vena cava is one of the main veins of the human body, it is responsible for receiving blood from the head, neck, upper chest and upper limbs. It is formed by the union of the right and left brachiocephalic veins, they originate from the junction of the subclavian vein with the internal jugular vein to form the right and left brachiocephalic venous trunk, both trunks join or merge into a single trunk and they form the superior vena cava, which flows into the upper part of the right atrium.
