The answer is A.

<em>The words polar and tropical indicate whether the air mass is cold or hot</em>. The word maritime tells that the mass was formed over the water and will be moist, while the word continental tells that the mass was formed over land and will be dry. so that case its cold a dry.

Answer:

B

Explanation:

Warm because land gains heat faster than water when heated by the sun. The heated land then transfers the heat to the atmosphere. The air mass is dry becasue a continent is mainly land and very little water (unlike oceans). There is, therefore, very little moisture in the continental tropical air mass.

The bulk of carbon dioxide is carried chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the RBCs.
e-lub [12.9K]

Answer: True

Explanation:Carbon dioxide is transported is transfer in 3 basic ways to human cells.

About 20 % of C0 2 is transported as Carbaminohemoglobin to reach the lungs carbon dioxide binds directly to the amino acid moieties on the globin portions of the haemoglobin to form carbaminohemoglobin. This is a reversible reaction as shown below.

                                        CO2 + Hb ↔ HbCO2.

The reversible binding of C02 to the haemoglobin is due to the   the partial pressure of carbondioxde. In  the  lungs the partial pressure of C02 is low. Therefore C02 is unbounded from the HB and leaves in the lungs, thus the blood   leaving the lungs for the body tissues has low partial pressure C02. Compare to the blood in the tissues with high partial pressure of C02 from metabolic activities of cellular respiration. The C02 therefore diffuses from the tissues to bind with HB to form Carbaminoheamologbin.

In addition C02 is transported by other means.

1. As bicarbonate 70% of the Co2 in the blood is transported and  bicarbonate buffer.

              CO2 + H2O CA ↔ H2CO3↔H+ + HCO3

2, As  soluble carbon dioxide which  dissolves directly  in to the blood stream; this is about 7-10%

How does the chance of a coin landing on each side compare to the chance that a gamete cell will receive a particular gene at me
tresset_1 [31]
The chance of a coin landing heads or tails is 50% for each individual time. It doesn't matter what the previous throws resulted in. If you flip a coin ten times you can get ten heads, but the probability is still 50% for each toss. The same holds true with gametes. The probability is 50% at the production of each individual cell.

Maggie's Plant Experiment In this exercise you will read the following scenario and identify the parts of the scientific method
ANTONII [103]

Answer:

Please find the identified steps of the scientific method below

Explanation:

A scientific method is a series of steps that aims at solving a problem. The steps in a scientific method include:

1. Making observation: In this experiment, Maggie observed when she read that some plants grow better if the soil is acidic. This is her observation that led to the scientific question: Do plants grow better in an acidic soil?

2. Formulating hypothesis: Hypothesis is a testable explanation to a problem. In this experiment, Maggie's hypothesis is; IF acid is added to the soil, THEN plants will grow better

3. Test hypothesis: the hypothesis is tested by conducting an experiment. In this case, Maggie places two geranium plants of the same size in two pots. Then she added a tablespoon of vinegar to one of the pots and allows the other grow normally without acid. The independent variable in this experiment is the vinegar added while the dependent variable is the height of the plants. The plant group with the vinegar is the experimental group while the plant group without vinegar is the control group. The constants of this experiment are same sunlight, same amount of water, same location etc.

4. Analyse data: The growth of the control and experimental plants were measured every week for five weeks by measuring their heights. The height (cm) of the plants with vinegar for the five weeks as as follows: 10.0, 12.4, 14.8, 18.0, 21.4 while the height in cm for the plants without vinegar for the five weeks is as follows: 10.0, 11.5, 13.0, 15.7, 17.8.

5. Conclusion: Based on the result, the plants exposed to vinegar grew better each week except week 1, which is the week they started. Hence, the hypothesis of this experiment will be ACCEPTED because the experiment proves it.
