Answer:
a
Explanation:
The following molecule is nonpolar and hydrophobic because the carbon and hydrogen atoms share electrons equally. The correct option is A.
What are nonpolar and hydrophobic?Non-polar molecules are those which can not be dissolved in water. These molecules have ends that are not dissolved in water. Hydrophobic is a quality of the substance that is not dissolved in water or repels water.
The image shows a polymer made up of three hydrogen atoms are bonded to the initial carbon atom. Two hydrogen atoms are joined to the next 12 carbon atoms. A carboxyl group is attached to the last carbon atom.
Since charges fluctuate, a momentary dipole moment exists in a so-called nonpolar molecule.
Thus, the correct option is A, The carbon and hydrogen atoms share electrons equally.

Is starch a simple sugar molecule?
Answer:
yes because Most carbohydrates can be broken down by digestion into glucose and these are the carbohydrates
Explanation:
Answer:
Simple vs Complex Carbs. Carbohydrates are sugars that come in 2 main forms – simple and complex. This is also referred to as simple sugars and starches. The difference between a simple and complex carb is in how quickly it is digested and absorbed – as well as it's chemical structure

Your task is to decide which dig site is most likely to produce Dimetrodon fossils. What kinds of information do you think would be most useful for making your decision?
To uncover Dimetrodon fossils, researchers must first research the dimetrodon's habitats, then go to modern-day replicas of those past ecosystems.
Dimetrodon fossils:Because its remains have been discovered in Texas and Oklahoma in the United States, Nova Scotia, Canada, and all throughout Europe, the Dimetrodon is likely to have been well suited to a broad range of environments.
The first fossil was discovered in the nineteenth century, and Edward Drinker Cope named it in 1878.

Many coniferous forests containing pine trees grow in the taiga, the largest habitat in the world. Using credible sources, such as NASA, research the typical climate conditions in coniferous forests. Explain why the structure of pinecones helps ensure successful reproduction in coniferous forests.
Answer:
Precipitation in coniferous forests varies from 300 to 900 mm annually, with some temperate coniferous forests receiving up to 2,000 mm/ year (79 in/year). The amount of precipitation depends on the forest location. In the northern boreal forests, the winters are long, cold and dry, while the short summers are moderately warm and moist. In the lower latitudes, precipitation is more evenly distributed throughout the year.
The climate conditions of coniferous trees normally have summer temperatures that range from -40°F to 68°F with seasons ranging with an average of cold, long, snowy winters, and warm, humid summers. With defined 4 seasons, and at least 4-6 frost-free months. The precipitation has about 12 to 35 inches of rain each year. The in these areas of course the vegetation they have is coniferous trees, but the main dominant trees are pines, spruces, firs, and larches. With mosses, liverworts, and lichens covering the main ground.

Explanation:
Diffusion is an important process in animals and plants.
The movement of many substances into and out of cells occurs by diffusion.
Describe why diffusion is important to animals and plants.
In your answer you should refer to:
• animals
• plants
• examples of the diffusion of named substances.
Answer:
Diffusion helps animals in respiration. The cells in an animal's body need glucose and oxygen for respiration. Both these are carried in the blood. When blood reaches the cells the molecules of glucose and oxygen diffuse out of the blood and into the cells. As cells use up the glucose and oxygen they produce waste chemicals and carbon dioxide.
Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. This helps the plants to photosynthesize and produce more food.
Example for animals: Animals using glucose and oxygen in diffusion.
Examples for plants: Plants using carbon dioxide to photosynthesize.

Temperature, rainfall, altitude, latitude, and the types of plants that grow there are used to identify biomes.
Aquatic biomes such as tundra, taiga or boreal forests, temperate deciduous forests, tropical rainforests, grasslands, savannas, deserts, and marine and freshwater habitats are just a few of the primary categories of biomes. Each biome has a different set of traits and characteristics that influence the types of plants and animals found there.
Therefore, match each biome with the correct description.

A. enabling pollen to grow fruit to encase the sperm and egg
B. enabling pollen to grow a tube to transfer sperm to the egg
C.transferring pollen from the anther to the pistil
D. transferring pollen from the ovule to the ovary
Please hurry and answer for me plz!
Bees, which are known for aiding in pollination, help with transferring pollen from the anther to the pistil. The correct option is C.
What is pollination?Transferring pollen grains from a flower's male anther to its female stigma is the process of pollination.
Every living thing, including plants, strives to produce progeny for the following generation. Making seeds is one method through which plants can create progeny.
Bees are necessary for the growth of plants and flowers. They use the pollination process, in which they move microscopic pollen grains from one blossom of one sort of plant to another flower of the same kind.
The transfer of this pollen aids in the growth of the blooms which will ensures that a plant will produce full-bodied fruit and a full set of viable seeds.
Thus, the correct option is C.

Explanation:
They are only found in ribosomes and the nucleus as either DNA or RNA
Answer:
[tex]\boxed {\tt Nucleic \ Acids}[/tex]
Explanation:
Nucleic acids are the monomers of genetic material, such as DNA and RNA. These structures are found in the nucleus and ribosomes because DNA is stored in the nucleus, RNA is made in the nucleus, and RNA is used to make proteins in the ribosome.
Cholesterol, proteins, galactose, and phospholipids are all cell membrane components. Nucleic acids are not. We know they are in the nucleus and ribosomes. Therefore, the correct answer is nucleic acids.

A. By producing insulin
Answer:
C. By storing glucose
Explanation:
By storing glucose, the liver makes sure that blood glucose levels remain steady between meals and during sleep. When blood glucose falls, cells in the pancreas secrete glucagon. Glucagon instructs the liver to convert glycogen to glucose, making glucose more available in the bloodstream.
