We could find a way to properly dispose of or recycle waist, and also keep factories in places with little life to hurt like deserts.
The only true answer here is B. if you have a periodic table, you can see that Magnesium atomic number is 12 while Aluminium's is 13. this means Al has 1 more proton and weights more than magnesium since proton and neutrons contribute to the weights of the atoms.
Answer: Valves in the veins
Explanation: The flow of the blood inside the body takes place through the veins and arteries. The oxygenated blood from the heart is supplied to the different parts of the body.
The blood flows from the capillaries to the venules and from there to the veins. The blood moves in the veins by the rhythmic movement of the smooth muscles in the body.
Most of the blood moves against the gravity so there is a chance that it can backflow so to prevent this there are valves in the veins known as one way valves.
Answer:
The three anatomical structures that, in order, contribute to the production of mature sperm are the epididymis, seminal vesicle and prostate.
Explanation:
The sperm and the first seminal fluid are produced and found initially in the seminiferous tubules of each testicle. From there they move on to several structures that contribute to the maturation process:
- Each <u>seminiferous tubule </u>drives the sperm to the epididymis, through the vas deferens, where the sperm can be for a long time and complete their maturation process.
- From the epididymis, the sperm pass to the seminal vesicle, which produces more seminal fluid to give nutrients to the sperm and facilitate its movement.
- Finally, and before being expelled outside, the seminal fluid receives the prostatic secretion in the prostatic urethra, a viscous and whitish liquid that completes the seminal fluid content.
The process of maturation of sperm is of importance for the process of sexual reproduction.

The two organisms that are most closely related according to Linnaean taxonomy are <em>Felis catus</em> and <em>Panthera pardalis</em>, because they belong to the same family
<h3>What is taxonomic classification?</h3>
Linnaean system of classification consists of a hierarchy of groupings called taxon. Each taxon is arranged in a hierarchical order.
The hierarchical arrangement of the taxon are as follows:
- Kingdom
- Phylum/Division
- Class
- Order
- Family
- Genus
- Species
These taxa are arranged from the most inclusive to the most exclusive i.e. members of the same species are the most closely related in that order.
This suggests that <em>Felis catus</em> and <em>Panthera pardalis</em> are the most closely related because they belong to the same family.
