Answer:

Coral reefs are under threat if atmospheric carbon dioxide levels continue to rise, new research has shown. When CO2 dissolves in the ocean, it raises the water's acidity level. This prevents a build up of calcium carbonate, which corals draw from seawater to build their skeleton

The evolution of similar forms in different lineages when exposed to the same selective pressures is.

luda_lava [24]

The evolution of similar forms in different lineages when exposed to the same selective pressures is convergent evolution.

Convergent or divergent evolution are related to the involved groups, the environments, the selective pressures, and the way in which organisms deal with them to achieve a better adaptation increasing their fitness.

<h3>What is convergent evolution?</h3>

Convergent evolution is the emergence of phenotypical similarities in different groups independently from each other.

Convergent evolution occurs when two or more taxonomic groups share the same traits or characteristics even when they do not share a common ancestor.

Usually, this is a pattern observed in groups that are exposed to the same or similar environmental pressures. The development of these similar phenotypes is related to higher fitness and competitive ability.

The evolution of similar forms in different lineages when exposed to the same selective pressures is convergent evolution.

In carrier pigeons there is a rare inherited condition that causes the death of the chicks before hatching. In order for this di

blondinia [14]

Answer:

1. are heterozygous for the disease.

Explanation:

Since the disease causes the death of chicks before hatching, it means that those with the disease cannot be found in the population. In order for the allele of the disease to be passed from generation to generation, there must be parent birds that are carrying the disease in heterozygous state.

Option 1 is the correct option.

Mary and Tommy are measuring 10 grams of sugar on an electronic balance that measures to the hundredths of a gram. Tommy records

PolarNik [594]

Answer: The correct answer is Option C.

Explanation:

Precision refers to the closeness of two or more measurements to each other.

For Example: If you weigh a given substance five times and you get 3.2 kg each time. Then the measurement is very precise.

Accuracy refers to the closeness of a measured value to a standard or known value.

For Example: If the mass of a substance is 32 kg and one person weighed 31 kg and another person weighed 29 kg. Then, the weight measured by first person is more accurate.

According to the question:

Mass weighed by Mary = 10.00 g

Mass weighed by Tommy = 10 g

As, mass weighed by Mary is reported upto 2 decimal places. Thus, it is more precise.

Hence, the correct answer is Option C.

At list of processes associated with CO2 transport in the blood. Classify each process as occurring predominantly at peripheral

nataly862011 [7]

Answer:

a. CO2 is produced ---> occurs predominantly at the peripheral tissues

b. CO2 + H20 to form H2CO3 ---> occurs predominantly at the peripheral tissues

c. Bicarbonate combines with H+ to form H2CO3 ---> occurs predominantly in the lungs

d. CO2 diffuses into blood ---> occurs predominantly at the peripheral tissues

Explanation:

Peripheral gas exchange or internal respiration is the gaseous exchange that occurs between the blood and the tissues of the body across the walls of the peripheral capillaries in contrast to external respiration which is the exchange of respiratory gase, carbon (iv) oxide and oxygen, between the body and the external environment occuring at the lungs.

During respiration, carbon dioxide is removed from the body through the lungs while oxygen is taken into through the lungs.

Carbon dioxide is produced as a waste product of metabolism by the tissues of the body. Removal of carbon dioxide is of utmost importance and occurs in three distinct ways in the body:

1. First carbon dioxide is transported in dissolved form in the blood to the lungs.

2. Carbon dioxide combines reversibly with hemoglobin to form carbaminohemoglobin and is transported to the lungs where it dissociates from hemoglobin is removed via expiration

3. Carbon dioxide is transported in the form of bicarbonate in blood to the lungs where it removed by the following process : i) carbon dioxide produced in the peripheral tissues diffusers into the and into the red blood cells. (ii) The enzyme carbonic anhydrase converts it to carbonic acid (iii) Carbonic acid dissociates into bicarbonate and hydrogen ions. Hydrogen ions binds to haemoglobin while bicarbonate is exchange with chloride ion in the plasma. (iv) Bicarbonate is transported to the lungs in blood plasma. (v) At the lungs, bicarbonate renters the red blood cells in exchange for chloride ions. The bicarbonate combines with hydrogen ions released from hemoglobin to form carbonic acid. Carbonic acid is broken down to carbon dioxide and water by carbonic anhydrase in the red blood cells. Carbon dioxide diffusesout into the lungs and is expelled.

Therefore, the processes in the question above can be classified thus:

a. CO2 is produced ---> occurs predominantly at the peripheral tissues

b. CO2 H20 to form H2CO3 ---> occurs predominantly at the peripheral tissues

c. Bicarbonate combines with H+ to form H2CO3 ---> occurs predominantly in the lungs

d. CO2 diffuses into blood ---> occurs predominantly at the peripheral tissues
