Answer:
Challenge : Competition form other species.
Success : Adaptation and colonisation.
Explanation:
- Challenges like adapting to the new environment and different climatic zones and handle other potential threats like predators as snakes, birds, and others. Their potential to find food and sustain themselves will be a challenge.
- Success factors include their ability to adapt and develop a sense of the different environment and through genetic mutation and natural selection they can develop and grow in numbers.
Answer:
Explanation:
Antibodies have three main functions: 1) Antibodies are secreted into the blood and mucosa, where they bind to and inactivate foreign substances such as pathogens and toxins (neutralization). 2) Antibodies activate the complement system to destroy bacterial cells by lysis (punching holes in the cell wall).

Answer:
Transparent, translucent, and opaque.
Explanation:
Transparent, translucent, and opaque are the three categories of materials that has a relation with transmitted light. Transparent objects are those from which the light passes through e.g plastic, water etc while on the other hand, translucent objects are those from which some of the light pass through e.g sunglasses and wax paper etc and opaque objects are those from which no light can pass through their body e.g wood and metal etc.
Answer:
The most probable result of the increasing concentrations of fertilizers in the prime rivers emptying into oceans is eutrophication followed by hypoxia. This will eventually result in less uptake of carbon dioxide and less release of oxygen.
The fertilizers are among the common pollutants, which degrade the quality of water. The fertilizers comprise chemicals, which are good for plants use, however, the excess amounts used in plants get run off and pollute the water bodies.
The fertilizers mainly comprise nutrients like phosphorus and nitrogen. When it rains, these nutrients get carried to the water bodies and results in algal bloom known as eutrophication. This algal bloom utilizes the oxygen in the water, leaving behind no or fewer levels of oxygen that hampers life of aquatic species.
