Answer:

mutation

Explanation:

As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation

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.

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.

Answer:

its d repair crlls can't repair itself

Cell division is the division of cells through a series of events. It results in reproduction, growth and repair. Nutrition is not a result of cell division.

Cell cycle is a series of event where a cell grow, differentiate, accumulate nutrients, duplicates its genome and divide to form daughter cells.

Cell cycle has two phases in which one is interphase in which the cell grow and accumulate nutrition, along with this cell duplicates its genome. Second phase is M-phase in which cell division takes place.

Cell division helps cell in reproduction, growth and repair.

Thus, the correct option is b, as nutrition as it is not a result of cell division.

Answer: The Department of Agriculture and Forestry (Answer: A)

Explanation:This is 100% the correct answer. No cap.

Answer:

A

Explanation:

Answer: its C

Explanation:

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

Answer: Clonal progagation

Explanation:

Clonal propagation involves the production of identical individual without the fusion of germ cells. It can be multiplication through stem and other plants part such as leaves.

Strawberry as a fruits can be multiplied using the stems thus preventing the germ cells from genetic recombination that could lead to the formation of entirely new plants. It does not involve the union of male and female germ cells.

Answer: The caterogries are fruit and vegtables

Explanation: The fruits are: apple, orange, banana, pear, and grape.                  The vegtables are: peas, carrot, lettuce, turnip, and potato

We classify the given fruits and vegetables on the basis of true seeds and bogus seeds.

Seeds may be defined as a reproductive unit of flowering plants which are capable of inducing other identical plants.

Banana, potato, grapes, orange, apple, etc. have fleshy endocarp that surrounds either the true seeds or bogus seeds.

Sometimes, bogus seeds are not visible with our bare eyes.

Therefore, it is well-differentiated above.

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.

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.

A genetic sequence, the TATA box, is a transcriptions start site and initiates transcription through the formation of RNA polymerase. Negative regulation may inhibit the initiation of transcription and/or repress gene expression.

Explanation:

proteins called transcription factors bind to the TATA box, this triggers RNA polymerase to start synthesizing RNA to DNA

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.

The answer is "using wind energy to generate electricity".

Explanation:

The Wind turbines may not emit water or sulfur compounds (with rare exceptions) and require no water as a coolant. The cost of power produced from energy sources may also be reduced by windmills, which will result in lower overall air quality and hosing pollution, that's why Utilizing wind energy for energy production decreases human greenhouse gas sources.
