Answer: Possession of Valves
Explanation: Veins possess valves which ensures that blood flows in only one direction. Valves helps blood to flow back to the heart against gravitational force.
Arteries don't have valves because the pressure originating from the heart is capable of causing the blood to flow in one direction.
The regression equation is:
y = 1.15 – 0.251 x₁ + 0.078 x₂ + 0.306 x₁x₂

Where,
x₁ = -0.2508
x₂ = 0.0777
x₁x₂ = 0.3058
Inserting the values,
<span>
<span>
</span></span>y = 1.15 – {0.251 × (-0.2508)} + {0.078 ×(0.0777)} + {0.306 × (0.3058)}
</span></span></span>
y = 1.15 - (- 0.0629508) + 0.0060606 + 0.935748
y = 1.15 + 0.0629508 + 0.0060606 + 0.935748
y = 1.3125862
Answer:
x₁ and x₂ are main effects (a type of tuna and type of packing liquid) that contribute significant information for the prediction of <span>y.</span>
Answer:
Explanation:
The green algae lineages hypothesized to be most closely related to land plants include: Coleochaetophyceae (coleochaetes). Charophyceae (stoneworts).well lack of vascular tissue—specialized groups of cells that conduct of water or dissolved nutrients throughout the plants body.(i guess this the scientific evidenxe if not comment ill provide more information)
hope it helps
<span>A prokaryotic cell contains no membrane-bounded organelles.
</span>With this information, we can conclude that it is the eukaryotic cells that has genetic material surrounded by a membrane.
Explanation:
I don't know I just really need points at this point and need answers to a test so I'm sorry for this
