suggest a reason why termites have no eyes
Answer:
the pests have antennae covered with moisture-sensing receptors
Explanation:
Answer:
Many species of termites need to find areas of vegetation with plenty of moisture to survive. To get around their lack of vision, the pests have antennae covered with moisture-sensing receptors.They also have eyes but their wings do not develop further. These develop into the neotenics (see below), which are one of the reproductive types and have the ability to produce eggs in the colony in certain situations

What organism belongs to the Prokaryotic domain of life and it comes in three different
shapes, such as cocci, rod, and spiral?
Answer:
eubacteria
Explanation:
I took the quiz :)
The organisms that belong to the Prokaryotic domain of life and it comes in three different shapes, such as cocci, rods, and spirals are known as Eubacteria.
What do you mean by the Prokaryotic domain?The prokaryotic domain may be characterized as the kingdom of Prokaryotes is significantly made up of two domains namely, Archaea and Bacteria. These eubacteria are classified under the domain of bacteria which is represented by the relation based on the DNA experimental approach.
According to the context of this question, there are mainly three types of eubacteria commonly found. They are round (coccus), rod-like (bacillus), comma-shaped (vibrio), or spiral. All these types of different body plans, structures, and functions with respect to their morphology.
Therefore, eubacterium is a type of organism that belongs to the Prokaryotic domain of life and it comes in three different shapes, such as cocci, rod, and spiral.

What are the four functions of lipids
Answer:
Store Energy – When we take in more energy than we need, the body stores it as adipose tissue (fatty tissue, which we call fat).
Regulate and Signal – Lipids regulate the temperature of your body, keeping it steady, not too hot, and not too cold.
Insulate and Protect – Our bodies are padded with fat, protecting us from everyday friction.
Aid Digestion and Increase Bioavailability – When food breaks down in the gut, fat is released and combines with fat-soluble nutrients
Explanation:
Beaches are monitored to protect public health. Waterborne pathogens can cause illnesses. Which of the following ways can pathogens enter coastal waters?
Leaking sewer pipes and untreated wastewater
Precipitation through the water cycle
The changing of low tide to high tide
Through the interactions of marine organisms and plants
Waterborne pathogens can enter coastal waters via leaking sewer pipes and untreated wastewater.
Sewage and untreated wastewaters are filled with microbes some of which are capable of causing diseases to humans and livestock if given the opportunity. Hence, the seeping of these waters into coastal water is a risk to humans who might want to swim or make use of coastal waters.
Precipitation, changing of tides and the interactions of marine organisms and plants will ordinarily not form pathways through which pathogens can gain access to coastal waters.

Sofia’s favorite meal is breakfast, and she is careful to include healthy components along with her favorite foods. She knows breakfast helps to keep her energy levels up until lunch. Sophia's digestive system helps her body get energy from food. How do the nutrients from food get to the body's cells? A. The nutrients are distributed by the digestive system to the parts of the body that need them. B. The nutrients are picked up and transported around the body by blood from the circulatory system. C. The nutrients are absorbed directly into the cells that need them. D. The circulatory system brings nutrients to the digestive system to be processed for the cells.
Answer: c
Explanation:because it needs cells I think…
The nutrients from the food get to the cells of the body by the action of two organ systems i.e. the digestive system and the circulatory system.
What is the role of the digestive system?The digestive system may be defined as a type of organ system that significantly deals with the breakdown of food substances into simpler components that can easily be consumed by the body.
According to the context of the question, the food that we eat reaches the stomach through the esophagus where multiple enzymes perform their roles. After the stomach, the food may be passed to the small intestine which is absorbed here and then the nutrients assimilate in the blood.
Through the blood, the nutrient can be transported around the body by blood from the circulatory system. Thus, the correct option for this question is B.
