The timing of changes to locomotor adaptations, brain size, and canine size in hominins follows a pattern that can be explained by evolutionary processes.

As hominins evolved and adapted to different environments and lifestyles, their locomotor adaptations, brain size, and canine size underwent changes over time. For example, the transition from quadrupedalism to bipedalism resulted in changes to the pelvis and leg bones, which allowed for more efficient walking and running. As hominins began to rely more on tool use and social cooperation, their brain size increased to support these activities. Canine size also decreased as hominins shifted from a diet that included more tough, fibrous vegetation to one that included more meat. Overall, these changes followed a gradual pattern of adaptation and evolution over millions of years.


1. Locomotor adaptations: The first major shift in hominin evolution was the development of bipedalism, which allowed our ancestors to walk upright. This adaptation likely occurred around 6-7 million years ago, providing greater mobility, energy efficiency, and the ability to use hands for tool use and other tasks.

2. Canine size: As hominins adapted to new environments and diets, there was a gradual reduction in canine size. This change began around 4.4 million years ago, as smaller canines became more advantageous for a wider variety of food sources and social interactions.

3. Brain size: The expansion of the brain is a key feature in human evolution. While early hominins had smaller brains, the brain size began to increase significantly around 2 million years ago, coinciding with the emergence of the Homo genus. This allowed for the development of more complex cognitive abilities, problem-solving skills, and social behaviors.

The pattern of changes in locomotor adaptations, brain size, and canine size in hominins can be described as a sequential, adaptive process in response to various environmental pressures and selection factors throughout their evolution.

Answer:

C. Closure of stomata

Explanation:

Abscisic acid (aka ABA) is a plant hormone that plays a role in the stress response, particularly in response to water stress.

When a plant senses that water is in short supply, it produces more ABA, which then signals the plant to close its stomata (small openings on leaves that allow for gas exchange) in order to conserve water and prevent dehydration. So, out of the options given, the promotion of closure of stomata is the response that is promoted by abscisic acid as a part of stress response.

option D is partly correct, but it's not specific enough to identify the role of ABA

C. All cells come from existing cells.

Explanation:

Schleiden observed plant material and concluded that all plant tissue was made up of cells, which helped to establish the cell theory that all cells come from existing cells.

The distribution of organisms provides evidence for evolution through patterns observed in geographic distribution, endemic species on islands, and changes in distribution seen in the fossil record.

Observations regarding the distribution of organisms provide valuable evidence for evolution. One such pattern is the geographic distribution of species. Similar environments often contain distinct yet closely related species. This can be observed in different regions around the world.

For example, the marsupials in Australia, such as kangaroos, koalas, and wombats, show remarkable similarities in their reproductive and developmental characteristics. These similarities suggest a common ancestry and adaptive radiation in response to the unique Australian environment.

Another significant observation is the presence of endemic species on islands. Islands provide isolated habitats, allowing for unique evolutionary processes to occur. The Galapagos Islands, famously studied by Darwin, exhibit an array of species found nowhere else on Earth.

The finches he observed there had different beak shapes and sizes, each adapted for specialized feeding habits. This diversification is thought to have occurred through natural selection acting on a common ancestor.

Furthermore, fossil records indicate that the distribution of organisms has changed over time. For instance, the discovery of similar fossils in South America and Africa suggests that these continents were once connected, supporting the theory of continental drift and explaining the presence of related species in both regions.

James Hutton's idea suggested that the earth was ancient. Charles Lyell built upon this idea by suggesting that the earth's geology has been changing since ancient times and is still changing. Darwin concluded that natural selection occurred and that fossils are old because of these ideas.

James Hutton's theory of uniformitarianism proposed that the geological processes that we see happening today, such as erosion and uplift, were also happening in the past. Hutton suggested that the Earth was ancient and had changed gradually over time, rather than being shaped by catastrophic events such as floods or earthquakes. Charles Lyell, a geologist who lived during Darwin's time, built upon Hutton's ideas. Lyell believed that the Earth's geology had been changing since ancient times and was still changing. This theory, called uniformitarianism, suggested that the processes that had shaped the Earth in the past were the same processes that were shaping the Earth in the present. Darwin used the ideas of Hutton and Lyell to support his theory of evolution by natural selection.

Chylomicron is a lipoprotein that transports dietary fat to the cells in the body.

Chylomicrons are extremely low-density, large lipoproteins that transport dietary lipids from the intestine to tissues.

Chylomicrons include triglycerides and other lipids absorbed by enterocytes to incorporate them into the body.

By being activated by the Apolipoprotein CII Protein, the body ensures that lipoprotein lipase only acts on mature lipoproteins.

This enzyme hydrolyzes the triglycerides that form the monolayer of the chylomicron, allowing the uptake of lipids by the muscle or connective cells that will use those lipids.

Therefore, we can conclude that chylomicrons are responsible for mobilizing the lipids that are ingested in the diet by the body.

Bees help the decay process by aiding in the breakdown of organic materials through pollination. They transfer pollen from one flower to another, which is necessary for plant reproduction. This in turn helps to propagate the decaying process as new plants spread and die, bringing more organic materials into the decay cycle.

Bees spread pollen between flowers, which is known as bee pollination. Pollen exchange results in fertilisation, which enables plants to develop seeds. A bee's diet is made up of floral nectar and pollen. Bees rely on pollen, a powdery, yellow material, as their main source of protein. Bees rely on nectar, a sweet, sugary liquid, for their source of carbohydrates. Buzz pollination is offered by some bee species. Buzz pollination is a method of pollination in which bees quickly vibrate their wings to induce pollen release from a bloom. In essence, they "shake" the pollen from the flower.

The process of decay is a crucial part of the nutrition cycle because it converts dead organic matter into nutrients that other living things, typically plants, may utilise. An organism's body begins to disintegrate pretty quickly once it dies. Enzymes that break down proteins and other biological components in tissues are released by dead cells. In addition, creatures like worms, bacteria, and fungi arrive to aid in the breakdown of the organic components. Decomposers are the organisms that facilitate the breakdown process. They are categorised as saprotrophic because of how decaying bacteria and fungi break down dead organic molecules. They eat decaying stuff since they are unable to manufacture their own sustenance.

The movie clip provides insights into the digestion of food and the changes that occur as it moves through the digestive tract. Mainly, the clip highlights the importance of the digestive system in breaking down food and extracting nutrients.

It emphasizes that digestion begins in the mouth, where food is mechanically broken down through chewing and mixed with saliva, which contains enzymes to initiate the digestion of carbohydrates. The partially digested food then travels through the esophagus to the stomach, where it is further broken down by stomach acids and enzymes.

Next, it moves to the small intestine, where the majority of nutrient absorption takes place. Here, the food is broken down into smaller molecules by enzymes and absorbed into the bloodstream.

Answer:

The two nucleotides are located on DNA strands that are parallel to each other

Explanation:

Deoxyribonucleic acid, commonly known as DNA, is one of the two types of nucleic acids. It is a molecule composed of a nitrogenous base, pentose sugar and a phosphate group. According to the information given in this question, Adenine is the last nucleotide at the 3' end of one strand of DNA. The following are factual about the nucleotide;

- Since DNA is a double-stranded molecule, the Adenine nucleotide will be base-paired with Thymine nucleotide (complementary base pairing) on the other DNA strand.

- Since complementary DNA strands are opposite to one another, this means that if the adenine has an unlinked 3' hydroxyl group, then the thymine must have an unlinked 5' phosphate group.

- Nucleotides in a DNA strand are joined to one another via a covalent bond called PHOSPHODIESTER BOND. Hence, the adenine and the thymine are each bonded to the previous nucleotide in the strand by a phosphodiester bond.

- In the complementary base pairing between two nucleotide bases, there are two hydrogen bonds between the adenine and thymine nitrogenous bases i.e. A=T.

- DNA strands that make up a molecule are complementary and opposite to one another, hence, they are said to be ANTIPARALLEL.
