Answer:
Traits are coded for in DNA, specifically in genes.
Explanation:
DNA, as you probably already know, is made up of long sequences of nucleotides of A's, T's, C's, and G's. When transcripted into mRNA and translated into proteins in ribosomes, the order of these nucleotides signal which amino acids to produce for the protein. Proteins are extremely important and have many roles throughout the body, which means they actualize the code of DNA into physical traits. I hope this helped.
Why are theories important to science, if they cant be proven? Can they be changed/ modified? ( Please answer simply)
Answer: A scientific theory cannot be proven correct because there is no way to look into the future and find out if the theory is ever revised. Theories tend to change greatly as new discoveries are made.

Question: The functions of a particular cell structure are described below:
It allows waste to exit the cell.
It allows chemicals required for cellular respiration to enter the cell.
It regulates the movement of water into and out of the cell.
Which cell structure do these statements describe?
Answers:
A: endoplasmic reticulum
B: lysosome
C: mitochondria
D: plasma membrane
Answer:
b
Explanation:
The cell structure that allows waste to exit the cell is Lysosomes. It is the garbage disposal of a living cell. It eliminates all the waste materials through the process of degradation.
What do you mean by Cell structure?Cell structure may be defined as a structure that contains all those components with specific functions essential to carrying out life's processes.
The cell structure that allows chemicals required for cellular respiration to enter the cell is Mitochondria.
The cell structure that regulates the movement of water into and out of the cell is the Plasma membrane.
Therefore, each cell structure is defined above with respect to its functions.

A group of marine scientists introduced a species of fish into an artificial habitat and wanted to determine if it will grow well in the new environment. They recorded the population over several years and their data is plotted below. Analyze the data and formulate a conclusion. Does this species of fish do well in this habitat? Predict what will happen to the population over the next five years.
Answer:
It will be increased by a lot over the nect five years
Explanation:
Answer:
This species of fish don't do well in this habitat, we can see this because in 9 years the number of individuals went from 100 to 63, which is 37 individuals less. Over the next five years, the population will continue to decrease.

Answer:
pharma disposal waste, Medical waste disposal
The one example of U.S. consumer waste from the bulleted list is the pharmaceutical wastes and medical wastes.
What is pharamaceutical wastes?
If translated to the pharmaceutical chain, prevention of waste withinside the prescribing and shelling out degree is the maximum preferable, observed through redispensing and recycling medicinal drug that stays unused at some stage in the deliver and use chain.
Two strategies of removing medical waste consist of incineration or autoclaving. Incineration is a system that burns clinical waste in a managed environment. Some hospitals have one incineration generation and system available.

Which remains the same during a chemical reaction?
Answer:
In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction
Because matter is not created or destroyed in a chemical reaction, the total mass of reactants is the same as the total mass of products.

Crossing-over
A. increases genetic diversity
B. ends meiosis
Answer:
A. increases genetic diversity
Explanation:
Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation.
Read the following passage from the Biology Department at University of California, Berkeley.
Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.
Which of the following best describes how the population has evolved?
The population has not evolved because there was no change in allele frequencies.
The population has not evolved because it has grown.
The population has evolved because it has grown.
The population has evolved because there was a change in allele frequencies.
Answer:
the last one sorry if i'm wrong
Explanation:
According to the passage from the Biology Department at University of California, Berkeley.Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.
The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.
What is population?The term population reffered to the total number of people living in a particular given area.The population of an organism can't survive if it exceeds it's carrying capacity.
The causes that affect population growth animals that if there are more plants than usual in area, populations of animals that eat that plant may increase.
If animal population increases the population that eat that animal might also increase.
The effects of animals population can be dangerous and when population exceed the carrying capacity of their environment, animal suffer of malnutrition and disease.
When predictors became scarce due to over population, the weekar species of animal start or die in other ways .
The accurate description of the growth of a natural animal population is limited by environmental factors.
Therefore,The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.

Hemophilia A and red-green color blindness are examples of X-linked recessive diseases. Color blindness to red and green. Red-green color blindness prevents a person from recognizing red and green hues (usually blue-green). Otherwise, though, they can see normally. Thus, option C is correct.
What allele for color blindness located on X chromosome?Females have two X chromosomes, while males have one X and one Y chromosome. The X chromosome is where the genes that might cause red-green color blindness are handed down. Men are more likely than women to have red-green color blindness, since it is X-chromosom-inherited.
One of the most prevalent genetic (inherited) disorders in the world is color blindness, which means it is typically inherited from your parents.
Therefore, the allele for color blindness is located on the X chromosome, color blindness is sex-linked.
