Answer:

The Red blood cell, (or erythrocyte) is a cell typically without a nucleus.

Explanation:

The thing that makes them red would be pigment hemoglobin, and help transport oxygen and carbon dioxide to and from all of the tissues. Red blood cells are surprisingly made from at the end of your bones.

Answer:

Red blood cell is a blood cell which contains hemoglobin necessary for the transport of oxygen in blood from one part of body to another part.

Explanation:

These are the most abundant cells in the blood and are developed from liver and yolk sac in fetus while from the bone marrow in children and adults. Red blood cells (RBCs), also called erythrocytes, are cells that circulate in the blood and carry oxygen throughout the body. These cells are produced in the bone marrow and are released into the bloodstream as they mature. RBCs typically make up about 40% of the blood volume. The normal RBC range for men is 4.7 to 6.1 million cells per microliter (mcL). The normal RBC range for women who aren't pregnant is 4.2 to 5.4 million mcL. The normal RBC range for children is 4.0 to 5.5 million mc.

Han takes a shower in his family’s new apartment. He gets the water perfect—not too hot, because that hurts! Then Han hears his
tester [92]

Answer:

  1. Unconditioned stimuli, US: getting hurt by hot water.
  2. Conditioned stimulus, CS: hearing a toilet flush.
  3. Unconditioned response, UR: feeling pain after hurting.
  4. Conditioned response, CR: being afraid when hearing a toilet flush.

Explanation:

  • Unconditioned stimuli: Biologically significant stimuli that provoke an unlearned or reflex reaction. For example, getting hurt by hot water.
  • Conditioned stimuli: neutral, innocuous or biologically not significant stimuli. For example, hearing a toilet flush.
  • Unconditioned Responses: Unlearned response that is triggered by reflex because of an unconditioned stimulus. For example, feeling a lot of pain after hurting by hot water.
  • Conditioned Responses: These are provoked by conditioned stimuli. This refers to a learned response that reflects the association between conditioned and unconditioned stimuli. For example, being afraid when hearing a toilet flush.

Initially, an unconditioned stimulus does not provoke any response, but after enough exposition to conditioned and unconditioned stimuli together, the simple presence of unconditioned stimuli induces conditioned responses. In this aspect, the subject has learned to predict or to anticipate the unconditioned stimulus.

Paha777 [63]

The question is stated incorrectly. The correct question is as follows;

The site of intercellular communication between a neuron and another cell is the.

Answer:

Synapse.

Explanation:

Neurons have dendrites, cell body and axons. Millions of neurons are present in the nervous system. Different types of neuron are sensory neuron, motor neuron and interneuron.

Synapse may be defined as the gap between the two consecutive neurons. The junction between the two neurons that helps in the intercellular communication. The neurotransmitters are diffused directly and transmit information through these synapse.

Thus, the correct answer is synapse.

in the reaction c o2 → co2, 18 g of carbon react with oxygen to produce 72 g of carbon dioxide. what mass of oxygen would be nee
Strike441 [17]
From the given balanced chemical reaction,
                                   C + O2 -> CO2
the mass ratio of the carbon and oxygen that is needed for the reaction is 12:32. Simplifying the ratio gives 3 unit mass C is to 8 unit mass O2. Given 18 g of carbon,
           18 g x (32 g oxygen / 12 g carbon) = 48 grams. 
For the given product, the ratio of oxygen to carbon dioxide is 32: 44.
                      72 g CO2 x (32 g O2 / 44 g CO2) = 52.36 grams
