A preservation biologist conducted an experiment on two islands (A and B) of similar size, climate, species composition, and richness. Originally, a large population of the same invasive species, a brown tree snake, was present on both islands. It had led to the extinction of some native lizards and forest birds. In her experiment, the biologist removed the brown tree snake from island B but not from island A. She then recorded the number of animal species on each island over a period of 24 months. The data collected is shown in the graph below:
Analyze the data above in terms of interspecific relationships and communities. Which statement best explains the difference in species present on each island over the course of the experiment?
The scientist is the ecosystem engineer of island B.
The brown tree snake was a keystone species on island B.
The brown tree snake is a foundation species on island A.
The brown tree snake is the ecosystem engineer on island A.
Answers
Boiga irregularis or brown snake is a slender, climbing snake with a vertical pupil and large eyes, providing it better nocturnal vision. The species has no natural predator. When the brown snake is accidentally released into the island, it will result in local extinction of the majority of the island's native lizard and bird species.
It will also result in cascading ecological influences by eradicating native pollinators, resulting in the corresponding reduction of the native plant species.
Hence, the correct answer will be fewer birds and more snakes.
Ecosystemic engineers might affect the ecosystem structure and community dynamics. Option D. The brown tree snake is the ecosystem engineer on island A.
What are ecosystem engineer species?
Ecosystemic engineers are organisms that can modify the environment in which they live, influencing other species by changing biotic and abiotic factors and affecting resources availability.
Usually, the interaction of ecosystemic engineers with other species has a consequence on the ecosystem structure and equilibrium.
Based on this concept, many invasive species are considered ecosystemic engineers.
Invasive species are uncontrollable and provoke significant damage to the structure of native ecosystems, affecting endemic species. They produce ecological imbalances in the trophic chains and the dynamics of communities.
By affecting the structure of native ecosystems, they produce cascade effects in resident biota, altering the composition and habits of species in the region and modifying physical and chemical conditions in the environment.
The statement that best explains the difference in species present on each island over the course of the experiment is that The brown tree snake is the ecosystem engineer on island A. Option D.
As we can see, in the presence of the brown tree snake, many species suffered extinction on island A, probably by both direct and indirect effects of the invasive snake.
Island B, on the other hand, kept plenty of species diversity. This is because the snake was removed from the island. Native species managed to increase their population size and to establish again.

What five factors affect photosynthesis and its rate? How?
Answers
Answer:
Ans - 1 Photosynthesis begins with the light reactions. It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast.
Ans-2 The dark reactions of photosynthesis occur in the stroma of the chloroplast where they utilize the products of the light reaction. In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose.
Ans-3 The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

1. explain how body plan and anatomy enables invertebrate to perform essential functions it needs to survive.
2. explain how body plan and anatomy enables chordate to perform essential functions it needs to survive.
3. explain how body plan and anatomy enables primate to perform essential functions it needs to survive.
Answers
Answer:
1)Invertebrates are known as creatures that do not have backbones. Even though these creatures do not have backbones, they have been uniquely designed in order to survive. According to studies, most of these creatures are found in the sea and one of them is the Star Fish or also called as the Sea Star. Starfish's functions and ability to survive is not the same like other animals which make them unique in a different way. The starfish's body is hard and bony for protection purposes and they exist in a variety of colors for camouflage. Their essential functions in order to survive are as follows:
-The Ability to Regenerate: Starfishes have the ability to grow damaged and lost limbs or even their entire body as long as the center part is still present and intact. And this is their way of reproduction as well.
-Having Tube Feet: Its arms are covered with a suction-like tiny cups of tube feet. This unique design of the starfishes enables them to move and secure themselves, especially on rocks and ocean floors.
-Unique Feeding Ability: Sea Stars don't have mouths nor teeth to ingest food. Rather, these creatures have the ability to push open or turn their stomachs out and digest its food. After digestion, their stomachs retract back to their bodies.
-Vascular System: How starfishes survive does not rely on having hearts, brains and blood. Rather, they use the seawater. The seawater serves as the one the circulates inside the sea stars' bodies and this is when nutrients and oxygen are being transported and absorbed.
2)Keep in mind invertebrates are those who have exoskeletons (outside skeleton) or are hydrostatic (no skeleton). This make up 95% of all animals for example an ant or sponge. For a sponge, all it has is tissues that enable it to allow water to flow out the tops.
Chordata are anything with vertebrates so a simple fish could suffice. THEY HAVE 4 SPECIFIC CHARACTERISTICS: 1.Notochord 2.Dorsal, hollow nerve cord 3.Pharyngeal slits 4.Muscual, an.al tail
This is us, we have thumbs, and vertebrates.
3)The bipedalism of primates puts their heads on a higher elevation and this allows them to see predators or prey from afar hence giving them advantage. Opposable thumbs on the hand and feet allow primates to grasp and handle objects effectively hence are able to make use of tools for hunting and etcetera

In an area where trees are growing taller, the giraffe population must adapt if it is to survive. Which statement BEST explains how the giraffes would be able to survive and reproduce?
F The genetic material for neck length within the offspring must mutate.
G The trait for longer legs would have to be a response to the change in the environment.
H The genetic material for smaller, shorter hind legs must exist within the giraffe population.
J The trait for longer necks must exist within the population and be inherited by the offspring.
Answers
Answer:
J. the trait for longer necks must exist within the population and be inherited by the offspring
Lamarckism was the theory was given by Lamarck and is based on physical changes. Giraffes would be able to survive when the traits of the long necks are inherited. Thus, option J is correct.
What is inheritance?Inheritance is the passing of the genetic material down the generation so that the beneficial traits that are essential for survival are passed from one generation to another.
When the trait essential for the giraffes to survive like long necks and legs are passed from one generation to another through reproductive methods then they will be able to survive.
Therefore, option J. trait for the longer neck must pass or be inherited by offspring.
