The seed offers the embryo protection, nourishment, and a mechanism to maintain dormancy for tens or even thousands of years, ensuring germination can occur when growth conditions are optimal. Seeds therefore allow plants to disperse the next generation through both space and time.
Answer:
The components of the fluid connective tissue are red blood cells, white blood cell and blood platelets
Explanation:
The connective tissues refer to tissues composed of some class of matrix. The blood is considered a fluid connective tissue which is composed of red blood cells (erythrocytes), white blood cell (leukocytes) and blood platelets (thrombocytes). Erythrocytes are cells that contain hemoglobin and whose function is to transport oxygen to the body. Leukocytes are cells involved in the immune responses which act to protect the body against both foreign pathogenic invaders. Finally, thrombocytes are cell fragments that form clots and stop bleeding.
Answer:Although VO2 max is a good marker of fitness, it does present some downfalls. You can't really get an accurate measure .
Explanation:So, one way to determine your max VO2 pace is to warm up, then run for 8 minutes at the maximum intensity level you can sustain for 8 minutes. If, for simplicity's sake, you ran one mile, then your VO2 max training pace is 8 minutes/mile.
This is not a concern to scientists because this is an indication that a new species may be formed or in progress from the interbreeding.
Explanation:
We know that species are the populations that can mate to produce fertile and viable progeny. Speciation occurs when new species is form by a population which has separated and become reproductively isolated.
The two dogs living in Africa and America can mate and produce healthy offsprings and they are phenotypically different.
The mating of horse and donkey are different species because they produce infertile mule.
When two population of species that are phenotypically different mate they have overcome the mechanism of reproductive isolation.
