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.
Answer:
Predict the possible genotypes and phenotypes percentages for the
offspring produced from the cross below if albinism is recessive in
humans. Albino male x Heterozygous female
aa X Aa = Aa, aa, Aa, aa
Explanation:
From the crossing above, it is right to say that albinism and non-albinism occur in a 50-50 ratio i.e 50% each. The genotype shows that there is 50% homozygous recessive albinism while there is also 50% heterozygous non-albinism. The phenotype reflects that there no dominance of albinism or non-albinism, they both share equal phenotypic characteristics
Hey!
The water cycle is driven by solar energy, see solar energy is what makes water evaporate, which needs to happen for precipitation to happen, and precipitation reaches earth in hail, snow, or rain which will run-off into oceans and evaporate or just eventually evaporate.
So, yes, solar.
The cost-benefit analysis done to investigate a proposed mine site would take into consideration the cost of environmental restoration after mining and the value of the ore to be extracted from the mine.
<h3>Cost-benefit analysis</h3>
This is an analysis done to assess the cost and benefits of actions.
For an action to be profitable, the benefits must be more than the cost.
In this case, for a mine site, the value of the ore to be extracted from the mine has to be more than the cost of having to restore the site after mining.
Every other cost can also come in but the two major ones are those highlighted.
