The correct answer is B -Eukaryotes.
“Eukaryotes are the organisms that possess a true nucleus (containing the DNA, which is the genetic material) and the membrane bound subcellular compartments ( also known as cell organelles) such as golgi complex, endoplasmic reticulum, mitochondria.
As per the given information in the question, cells of mushrooms, plants, and animals all have visible nuclei under a microscope.
Thus, it indicates that these organisms are eukaryotes.”
Answer:
In the 1960s, China's large population was growing so rapidly that there was a serious threat of mass starvation.
• The government established the world's strictest family planning and birth control program, promoting one-child families and provides contraceptives, sterilizations, and abortions for married couples.
• Married couples pledging to have no more than one child receive a number of benefits including better housing, more food, free health care, salary bonuses, and preferential job opportunities for their child.
• Between 1972 and 2011, the country cut its birth rate in half and trimmed the average number of children born to its women from 5.7 to 1

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%
Provided that there's no diagram, most molecules have particular areas on the molecules, called the "active area" that act as a lock to a particular substrate's molecular structure, providing the key.
An enzyme's active area is only able to be "unlocked" by a certain substrate's "key".
Answer:
<h3>All the plants are autotrophic because they can prepare their own food using photosynthesis.</h3>
Explanation:
Animals & fungi are not autotrophic because they can not perform photosynthesis. In order to perform photosynthesis they should contain photosynthetic pigment i.e. chlorophyll. These are absent in animals & fungi. Apart from this animals & fungi have reserve food materials in the form of glycogen on the other hand plants stores the food in the form of starch. Animals & fungi lacks chloroplast.
