Red blood cells pick up oxygen in the lungs. Blood travels away from the heart and lungs through the arteries. Red blood cells drop off oxygen to the cells through tiny tubes called capillaries. Blood then returns to the heart through the veins and the cycle begins again.

Describe two reflexes that infants display
SIZIF [17.4K]
Infants show many reflexes as soon as they come out of their mother. Two of them are the sucking reflex and the root reflex. The root reflex is when the baby's side of the mouth is touch and they will then move their head towards where the were touched, allowing them to latch onto the breast or the bottle for food. The sucking reflex pretty much explains itself. When the roof of the baby's mouth is touched, they will begin to suck as they will think/know that it is feeding time. 

Hope this helps!!

9.<br>(1 + tan²theta) cot theta<br>cosec theta<br>tan theta​
wolverine [178]

Answer:

Proved

Explanation:

Given

\frac{(1+tan^2\theta). cot\theta}{cosec^2 \theta}= tan \theta

Required

Prove

In trigonometry:

1 + tan^2\theta = sec^2\theta

So, we have:

\frac{sec^2\theta *  cot\theta}{cosec^2 \theta}= tan \theta

Express each identity as an inverse:

\frac{\frac{1}{cos^2\theta} *  \frac{1}{tan\theta}}{\frac{1}{sin^2 \theta}}= tan \theta

Rewrite as:

(\frac{1}{cos^2\theta} *  \frac{1}{tan\theta})/ \frac{1}{sin^2 \theta}= tan \theta

Express tan as sin/cos:

(\frac{1}{cos^2\theta} *  \frac{1}{sin\theta/cos\theta})/ \frac{1}{sin^2 \theta}= tan \theta

(\frac{1}{cos^2\theta} *  \frac{1}{sin\theta/cos\theta}) * sin^2 \theta= tan \theta

(\frac{1}{cos^2\theta} *  \frac{cos\theta}{sin\theta}) * sin^2 \theta= tan \theta

(\frac{1}{cos\theta} *  \frac{1}{sin\theta}) * sin^2 \theta= tan \theta

\frac{sin^2 \theta}{cos\theta*sin\theta}= tan \theta

\frac{sin \theta}{cos\theta}= tan \theta

tan \theta= tan \theta
