All living things must contain genetic material. Which of the following nonliving things also has this characteristic? A. Fire B. Cell phone C. Virus D. Organic phosphates

Answers

Genetic material is the hereditary unit found in the cells of every living organism. Viruses are nonliving things that also have genetic material. Thus, option C is correct.

What are viruses?

Viruses are organisms that are living and nonliving as they reproduce when once inside the host cell and have the RNA or the DNA as the genetic material inside their capsids.

The protein shell of the virus includes one of the types of genetic material that infects the host DNA by taking control of the host machine to produce multiple copies.

Therefore, the virus is a non-living with genetic material.

Which of the following statements is not true about the digestive system and its contribution to homeostasis? A. The digestive system helps to maintain the correct amounts of nutrients for the body tissues to do its job. B. The digestive system is responsible for monitoring the oxygen and carbon dioxide amounts in the blood and tissues. C. The digestive system breaks down food sources into the needed nutrients and deposits these nutrients into the blood for use by the cells. D. All of the above

Answers

Answer;

B. The digestive system is responsible for monitoring the oxygen and carbon dioxide amounts in the blood and tissues.


Explanations;

Homeostasis involves the maintenance of a constant body environment.

The digestive system is not responsible for monitoring the amounts of oxygen and carbon dioxide in the blood and tissues. (It is the function of the breathing system together with the circulatory system).

Digestive system instead helps maintain homeostasis in a number of ways, For instance;

-By changing the pH from the saliva for example, which makes the gastric environment acidic which helps the break down of food readily and fast and also protect the body from bacteria.

The statement that is NOT true about the digestive system and its contribution to homeostasis is: The digestive system is responsible for monitoring the oxygen and carbon dioxide amounts in the blood and tissues. The correct answer is B. 

The Venus flytrap is a carnivorous plant that traps insects in a plant structure. The plant structure closes when the small hairs on the inside of the structure are touched. The Venus flytrap can attract insects using a special type of plant communication. How can plants, like the Venus flytrap, communicate with other organisms?

Answers

Answer:

Venus flytrap communicate with other organisms by secreting a sugary substance (nectar) in its leaf glands.

Explanation:

The Venus flytrap is a carnivorous plant that traps insects in a plant structure that closes when the small hairs on the inside of the structure are touched.

The leaf of this plant contains a watery fluid secreted by glands on its open traps. Organisms like flies are attracted to the secreted nectar and perches on it; only for the hairs of the flytrap to get shut due to that touch and cell expansion triggered.

Answer:

Option (C) is correct, The Venus flytrap plant traps the insect by producing a sticky substance, while the spider attracts the insect by producing a special odor.

Explanation:

Venus flytrap special features that help it to attract insects

From these results it is concluded that Dionaea attracts insects on the basis of food smell mimicry because the scent released has strong similarity to the bouquet of fruits and plant flowers. Such a volatile blend is emitted to attract insects searching for food to visit the deadly capture organ of the Venus flytrap.

__________ fats or lipids form animal body fat that is used for stored energy and insulation.

Answers

STORED
Lipids are macromolecules which provide insulation. 
A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

The polar head of a phospholipid is made of _______ molecules. a. phosphate
b. protein
c. carbohydrate
d. fatty acid

Answers

a. phosphate. The polar head of a phospholipid is negatively charged and is made up of phosphate molecules. This polar head region attracts water (hydrophilic) and is positioned outward to interact with water.

Both strands are copied to form Okazaki fragments, which are later annealed by DNA ligase. The replication process proceeds on both strands in the same direction, which requires that RNA primers bind to the lagging strand. 5.
