Which of the following classes of biological molecules consist of both small molecules and macromolecular polymers?A) lipidsB) carbohydrates
C) proteins
D) nucleic acids
E) lipids, carbohydrates, proteins, and nucleic acids all consist of only macromolecular polymers

Answers

Answer 1
Answer:

Answer:

(Correct option is B) Carbohydrates.

Explanation:

Biological molecules are known as the molecules which are found in the organisms, and play some important roles like development, cell division, and morphogenesis. They are necessary for the life.

Carbohydrates are known as the classes of biological molecules which consist of small molecules, and macromolecular polymers both. Carbohydrate are divided into three subtypes of essential macromolecules:

1) Monosaccharides: Fructose, galactose, and glucose are isomers of monosaccharide.

2) Disaccharides: Sucrose is the isomer of disaccharide.

3) Polysaccharides: Starch, cellulose, and glycogen are example of polysaccharide.

Glucose, and sucrose are known as the small molecules of carbohydrates, and other molecules of carbohydrate such as polysaccharides are known as macromolecular polymers.

What is the function of the central nervous system? A. to gather information
B. to carry a response to glands and muscles
C. to receive stimuli from the environment
D. to process information and form a response

Answers

Answer:

The correct answer would be D. to process information and form a response.

Central nervous system (CNS) is a part of nervous system that includes brain and spinal cord.

The brain is main controlling and processing unit of the body. The brain has four lobes (temporal, occipital, Parietal, and frontal lobe) in which different stimuli are processed and responses are generated.

The spinal cord acts as a connecting link between the brain and the rest of the body with the help of peripheral nervous system.

Together, brain and spinal cord process information and control all the voluntary and involuntary movements of the body.

Answer:

nervous

Explanation:

The nervous tissue is one of the four basic tissues of the organism, it is formed by two types of cellular elements, it represents the fundamental component of the structures and organs that make up the nervous system. The main function of the nervous tissue is to capture internal and external stimuli and transform them into nerve impulses. All modifications of the external or internal environment and sensory stimuli such as temperature, pressure, light, sounds and taste, among others, are detected, examined and transmitted by nerve cells. On the other hand, the nervous tissue is in charge of coordinating the motor, glandular, and visceral functions of the individual.

Without ribosomes, a cell would not produce a.lipids.
b.proteins.
c.salt.
d.water.

Answers

Answer:

b. proteins.

Explanation:

Ribosomes are cell organelles present in the cytoplasm of prokaryotic and eukaryotic cells. In prokaryotic cell ribosome is 70S (S is the Svedberg unit) type and in eukaryotes it 80S type. Besides in cytoplasm of eukaryotic cells, mitochondrial matrix and stroma of the chloroplasts have their own ribosomes similar to prokaryotic ribosomes. Ribosomes in association with endoplasmic reticulum provide platform for the synthesis of polypeptide (protein). The transcribed mRNA is translated into primary protein on ribosomes. Lipids are synthesised by smooth endoplasmic reticulum.

Fish, trees, and animals are important wildlife resources that we depend on for survival. Fish are a main source of food for many of the people in the world. Trees have been used to build and heat homes, make paper, and provide food for centuries. Humans hunt land animals such as deer, fox, antelope, and buffalo for food and other products. What can we do to protect wildlife resources so they will be around for future generations?

Answers

Answer:

harvest fast-growing trees, impose fishing limits, and impose laws to prevent poaching and illegal hunting

Explanation:

i got it right
We can limit fishing and hunting to certain seasons. This allows the population to increase and continue breeding, but we still get food. We can limit cutting down trees so that ecosystems can survive. Many species have lost homes due to deforestation. By cutting down only some trees in an area, we can still have wood to use, and we can save ecosystems.
