Answer:
In Anti-B box what can be seen are cells that are agglutinated when exposed to the anti-B antibody, which means that the blood type is B.
Explanation:
In reference to the ABO system, blood types are determined by surface antigens present on the erythrocyte membrane, so that
Blood type A has surface antigen A, but anti-B antibodies.Blood type B has surface antigen B, and anti-A antibodiesBlood type AB has A and B antigens, so it does not generate antibodiesBlood type O has no antigens, but can make antibodies to both antigens.This is the basis of compatibility by blood group, according to the ABO system.
What happens in the chart?It is an agglutination test, where samples of a blood type are exposed to anti-A and anti-B antibodies, to produce a reaction that destroys red blood cells that are sensitive to one antibody or another.
In the Anti-B box it is observed that the cells are agglutinated, so the blood type is B, sensitive to the exposure to anti-B antibodies. It is not sensitive to anti-A, because it produces them, which can be seen in the box that says anti-A.

Human-induced global warming using today's technology can be thought of as a
geologically temporary phenomenon. Why is this?
Answers
Human-induced global warming using today's technology can be thought of as a geologically temporary phenomenon because the carbon dioxide (CO₂) emissions from human activities, such as burning fossil fuels, are being released into the atmosphere at a much faster rate than natural processes can remove them.
What is global warming?Global warming is the long-term warming of the Earth's surface that has been seen since the pre-industrial era and is attributed to human activity, particularly the burning of fossil fuels, which raises the levels of heat-trapping greenhouse gases in the atmosphere.
Environmental changes brought on by global warming may have a negative influence on human health. Additionally, it can result in an increase in sea level, which poses a threat to biodiversity, a change in precipitation patterns, an increase in the likelihood of droughts and floods, and the loss of coastal land.

Answers
The two molecules that are classified as carbohydrates are used as a source of glucose to provide energy during cellular respiration, hence option C is correct.
How glucose provides energy?Carbohydrates polysaccharides and disaccharides provide the glucose units for cellular respiration and in protein, some amino acids are glucogenic, which are converted to glucose flow through cellular respiration and provide the ATP.
The initial process of breaking down glucose to release energy for cellular metabolism is called glycolysis. An energy-consuming phase and an energy-releasing phase make up glycolysis.

a. the chemical energy of the reactants
b. the chemical change of the product
c. the energy required to the reaction
Answers
Answer:
The correct answer is - option C.
Explanation:
Chemical energy is the energy that every substance or chemical have and its not affected by the presence or absence of the enzyme, while the activation energy is the required energy to initiate for a chemical reaction.

a. whale and human or whale and tuna
b. pig and rhesus monkey or pig and chicken
c. tuna and fly or tuna and chicken
Answers
Answer:
a. whale and tuna
b. pig and chicken
c. tuna and fly
Explanation:
Following, you will find characteristics of each species that differ in the contrasting groups. These descriptions reflect the divergence degree between groups.
a. whale and tuna
Whales: Vertebrate and Big-sized marine mammals. They are long-lived and pulmonate animals. They are relatively slow, and only breathe while they are on the surface, opening the blowhole which covers the narines. Despite being mammals, they lack hair, so they have naked soft skin. They have one dorsal fin, two lateral flippers, and a caudal horizontal fin, which they move up and down. They are viviparous, with internal fecundation, and females carry mammal glands to feed their offspring. They feed on krill and other small animals, which they filtrate using their baleens. Whales exhibit the Type I survivorship curve. Mortality often occurs at the end of the cycle. They have long cycles of life and high probabilities to survive until they are old enough. These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success. They are used to swim deep depth or near the surface depending on the reproductive cycle stage. Tuna: Bony marine fish. Fusiform and medium-sized body, fast swimmers. They can live for 15 years. Their body is covered with scams. They have two dorsal fins, two ventral fins, two lateral fins, and a caudal fin which they move from side to side. It swims near the surface and interchange gas using the grills. They have many teeth and feed on anything they can, such as small fishes, zooplankton, crustaceans, and mollusks. They have external fecundation and exhibit the Type III survivorship curve. Significant mortality during the early stages of life. Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life. These species produce big offsprings at the same time, but they provide little or no parental care. Their reproductive success relies on the number of descendants.b. pig and chicken
Pigs: Heary Mammal, with thick hairs, called bristles and mammal glands. They are four-legged, have hooves and four fingers. Their snout is long and flexible, with sharp teeth. They have a curly tail and thick and sensitive skin. Naturally, they are herbivorous but became omnivorous in captivity. They can live for ten or fifteen years. Viviparous. Well-developed smell sense and no sudoriparous glands. Territorial, dominant, and highly communicative with partners. They can use more than twenty different sounds. They also exhibit the Type I survivorship curve.Chickens: Birds. They have two legs and two wings however, it has never been successful in flying. Their body is cover by feathers. They have no hair, and they do not have teeth either, but they have a corneous peak instead. They are omnivorous. They show sexual dimorphism, especially in feathers and crests. They exhibit the type II survivorship curve. The probabilities of dying are equals all along the cycle, at any age interval. The number of dead individuals remains constant from the beginning to the end of the life cycle. These species have reduced offsprings, and they ensure their reproductive success by providing some significant parental care.c. tuna and fly
Tuna: Already described aboveFly: Flying and small-sized Insects. Dipterous, with their bodies divided into three regions: Head, thorax, and abdomen. They have six appendixes to walk, one pair of wee-developed wings, one pair of vestigial wings, eyes very sensitive to light. The mouthparts are used to lick, suck or bite. Some species can sting and suck blood from humans. Their body is covered with thin hairs and sensory bristles used to taste, feel, and smell. They are attracted by smelly matter, from which they feed on. In general, flies are associated to matter in decomposition and wastes. They have a short life cycle and can live up to twenty-five days. Ovoviviparous species, laying too many eggs that will turn into larvae and finally to the adult fly stage.Based on Model 3, the pairing of organisms that would have the most divergence in their DNA is: A. whale and human or whale and tuna.
What is genetics?Genetics can be defined as the scientific study of genes, chromosomes, heredity and the similarities or divergence (variations) of traits (DNA) in living organisms such as animals, humans, and plants.
Based on morphology and ecology, whales are aquatic and gigantic vertebrate (mammals) that only live in water. Also, whales are pulmonate and carnivorous animals that feed on other animals.
From Model 3, the number of amino acids differences between whale and human is ten (10) while that of whale and tuna is equal to seventeen (17). Therefore, we can deduce that the pairing of organisms that would have the most divergence in their DNA is whale and human or whale and tuna.

A fat may contain similar or different fatty acids attached to glycerol. ... If hydrogens are present in the same plane, it is referred to as a cis fat; ...
Explanation:
The triglycerides found in animals are solids while the triglycerides found in plants are generally liquids.
What do you mean by Triglycerides?Triglycerides may be defined as a type of ester that is considerably derived from glycerol and three fatty acids. They are the main constituents of body fat in humans and other vertebrates, as well as vegetable fat.
The Triglycerides that are found in animals are typically solid or semisolid. They have the same appearance and properties at room temperature and are classified as fats. Those triglycerides that are liquid are called oils and are derived chiefly from plants.
In animals, the carbon atoms in the fatty acids are saturated with hydrogen atoms. This permits them to lie straight and the molecules will pack neatly into a solid arrangement. In plants, missing hydrogen atoms cause kinks in the fatty acids which make the structure loosely compact, and thus they are liquids.
Therefore, the triglycerides found in animals are solids while the triglycerides found in plants are generally liquids.

1. Based on your graph, how many years will it take for the population of 2000 to double?
The graph illustrates exponential growth. Based on the properties of this graph, what does this term mean?
Answers
Exponential growth refers to a rapid and continuously increasing rate of population growth over time, resulting in a steep upward curve on the graph.
It took 1649 years for the world population to double, going from 0.25 billion people to 0.50 billion people. To double once again, it would take the same amount of time, approximately 1649 years. A third doubling would also take approximately 1649 years.
The population doubled for the second time in the year 1950. It took around 100 years for the population to double for the second time.
Extending the graph to the year 2015, you would add data points for that year. The specific values would depend on the available population data for that year.
According to the graph, the population is projected to reach 10 billion around the year 2050.
Based on the graph, it appears that the population of 2000 will double in approximately 40 years. However, since the specific year for the population value of 2000 is not provided, the exact number of years cannot be determined.
The graph illustrates exponential growth. This term means that the population is increasing at an accelerating rate over time. As the population grows, the rate of increase becomes more significant, resulting in a steep upward curve on the graph. This indicates a rapid and continuous growth pattern rather than a linear or constant rate of growth.
