HOW DOES STRESS AFFECT YOUR FOCUS???
Hint: The shallower our breath, the less oxygen that reaches our brain, and the harder it is to focus.
1: When you are stressed you start breathing more deeply and makes it harder to focus.
2: When you are stressed more oxygen gets to your brain and makes it harder to focus.
3. When you are stressed you start breathing more deeply and that delivers more oxygen to your brain helps you focus.
4. none of these

What are the substances?

Hi I need help in those two questions please don't type something that doesn't make sense for the points and have a good day

I will give brainly to correct answer and if you dont get brainly lmk if you want me to make a fr33 p01nts questions so you get brainly
Why is it necessary for organisms to undergo the process of respiration?

Respiration helps organisms capture vitamins from sunlight.

Respiration creates energy that is used for growth and repair.

Respiration limits organisms’ losses of water and oxygen.

Respiration constructs proteins needed for life’s functions.

i will give brainlst if the answer is right

how does the rock cycle support the explanation that "matter is never created or destroyed?"

Why do roots always grow in a downward direction, no matter which way you turn the seed or seedling?
because roots weigh more than any other plant part
because the plant’s stem begins to grow, and it pushes the roots downward
because that is the direction that roots find necessary water and nutrients
because the root contains hormones that make it grow away from the sun

genetically different cells produced in mitosis, meiosis, or both

Healthy human lungs look pink and spongy from the outside. The left lung is a little smaller than the right lung to make room for the heart. The lungs and heart are both protected by the rib cage. In the lungs, each main bronchus branches off into many smaller bronchi. The bronchi become smaller and smaller, and the smallest bronchi are called bronchioles. There are about 30,000 bronchioles in each lung, each about the same thickness as a strand of hair. The inhaled air eventually ends up in tiny air sacs called alveoli at the end of each bronchiole. There are about 300 million alveoli in each lung. They are covered with capillaries, tiny blood vessels that are only one cell thick. Oxygen travels from the alveoli through the capillaries to the bloodstream, heart and other cells.

Which of these best represents the progression of bronchi, bronchioles and alveoli in the lungs?

A
tree trunks that become smaller branches and twigs

B
a tight flower bud that has opened into a full bloom

C
whole apples that are sliced into separate wedges

D
a bridge that crosses two rivers
