Explanation:
fallopian tube
Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
Answer:
Codominant
Explanation:
Often, when an individual has two different alleles that determine its certain trait, the effect of the dominant allele will be expressed, while the effect of the recessive allele will be hidden. For example, this is how we inherit eye color.
However, it isn't always like this. Sometimes, the effects of both (different) alleles are expressed. This phenomenon is called codominance, and the scenario you were given is an example of it.

Explanation:
There is a proper mechanism of controlling the levels of various kinds of hormones and chemicals in our body called as positive feedback and negative feedback.
In a very simple language you can understand it as whenever there is a release of a particular hormone or chemical inside the body in very huge amount then the negative feedback of the body is activated the production of that particular hormone or chemical is stopped and vice -versa for negative feedback.
Explanation:positive feedback and negative both the feedback mechanism are achieved to maintain the proper homeostasis.
Example: release of clotting factor after blood loss is a positive feedback and a hormone is released and then suddenly there is a increase in hormone b, then the amount of hormone a will decrease this is a negative feedback.
Answer:
Savanna, is a biome, dominated by grasses. It exhibit dry climatic conditions. This biome receives very little rain fall. The tree population is scanty in this biome. The Savanna biome is found in Australia, Africa, South America and India. The giraffe is an animal that feeds upon leaves, fruits and pods of tall Savanna trees. The giraffe is tall enough to reach the highest branches of the trees.
As, in the given situation, more giraffe feed upon the leaves of the trees closest to the ground until all the leaves or vegetation of the ground and closest to the ground cleans up. Members of the population which have taller neck will be able to thrive leaves growing at the top of the tree canopy. This feature is called as natural selection. This involves the survival of the individuals, which have traits suitable for changing environment. The giraffe which have comparatively long neck will have better advantage for survival than the others in situations of scarcity of food.
