Why is it important that a healthy diet does not have a specific macromolecule composition?

Answers

Answer:

The correct answer is - each macromolecule has its own function and role in the body of an organism.

Explanation:

There are four major macromolecules that are essential for the energy and growth and development of an organism, are Proteins, carbohydrates, fat and nucleic acids. Each macromolecule is essential and found in various food sources so any specific macromolecule can not found in a healthy diet.

Proteins play various roles in the body such as support, building blocks, carriers, enzymes, and hormones. On other hand, carbohydrate provides energy for the cells, the transmission of the genetic information will be transferred by a nucleic acid. Fat also helps provide insulation, make lipid membranes.

Luís is a rock collector. He thinks that the material from his favorite sedimentary rock in his collection might have been part of an igneous rock formation under Earth’s outer layer millions of years ago. Could Luís be correct?

a.
Yes, energy from Earth’s interior can cause igneous rock to break into small rock pieces that form sedimentary rock.

b.Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock.

c.No, sedimentary rock can only form out of material from other sedimentary rock. There is no way that sedimentary rock can form from material in igneous rock.

d.No, sedimentary rock forms at Earth’s surface because energy from the sun causes rock to weather, but igneous rock under Earth’s outer layer is not exposed to energy from the sun.

Answer: A.

Explanation:

Palisade mesophyll cells contain the most amount of chloroplasts with an average of 30–70 chloroplasts per cell so they will be number 2 in the graph.

Spongy mesophyll cells contain less chloroplasts than their palisade counterparts to enable them have a larger surface area for gas diffusion.

The guard cells have the least amount of chloroplasts on average and so will be number 1. on the graph.

What else do you think plants may need to grow and go through their normal processes?

Answers

Plants need water, oxygen, soil, and solar energy.

Those are the only things that I believe plants need. They need water for food and Solar Energy (basically Vitamin D which you get from the sun) and soil to grow. Obviously they need oxygen to be able to survive.

What are 4 different protists and what makes them special

Answers

Answer:

Amoebalike protists, flagellates, ciliates, and spore-forming protists.

Explanation:

Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.

How do the nutrients found in plants function in plant DNA? Is the function of plant DNA similar to human DNA?

Answers

Answer:

How do the nutrients found in plants function in plant DNA?

Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.

Is the function of plant DNA similar to human DNA?

How much DNA do plants share with humans? Over 99%? ALL animals and plants share the same DNA which is basically a code of only 4 'letters' which code for the same amino acids from which all proteins are made.

HELP 25 POINTS AND BRIANLIEST IF CORRECT

Thoroughbreds are an example of a type of horse that results from selective breeding. However, not all thoroughbreds have the traits that are most desired. How has the process of selective breeding increased the probability that the horse will have a desired trait? Use information from the stimulus material and your knowledge of science in your answer. In your answer, be sure to:

Explain how selective breeding increases the probability that offspring will have a desired trait.
Explain why not all individual thoroughbreds may express the desired traits.

Answers

Answer:

If breeders Breed these horses with other breeds, the foal wont be a straight thoroughbred. So, it will change the horses breed.

Explanation:

Selective breeding increases the probability that offspring will have the desired trait because it limits narrows the gene pool to only include desired variants of a gene. Not all thoroughbreds may express the desired trait because they may inherit an unwanted variant of the gene & mutations may occur.

The traits and characteristics of an animal are determined by the genes they possess. When two animals breed, the offspring inherits one variant of each gene from both parents, known as alleles. This means that all animals have 2 variants for any specific trait.

When a gene in an allele is expressed, it means that the genetic code in that allele is the one that can be seen on the offspring. Gene variants can be classified based on how likely they are to be expressed as:

Dominant Recessive

When one allele is expressed and the other is not, it is because that allele is dominant and the other is recessive. Recessive variants for a gene will only be expressed if both alleles inherited by the offspring possess are recessive. dominant genes are symbolized by a capital letter and recessive genes with a lower-case letter.

Selective breeding is used to continuously breed animals that have similar variants of the desired trait. If breeding were to be natural, then many of what we consider desirable traits may be lost behind the expression of common, more dominant genes. Selective breeding is done by narrowing the gene pool, meaning that we only allow breeding between animals known to possess the desired trait.

Not all thoroughbreds may express the desired traits because sometimes even though a parent has the desired variant of a trait, they may also contain a different recessive or dominant variant of a trait. Since selective breeding does not control what variant exactly the offspring inherits, it does not always work with each offspring. Genetic mutations can also affect the outcome.
