Answer:
The stomach and the teeth both perform mechanical digestion, which is physically (as opposed to chemically) breaking the food into smaller components. This exposes a larger surface area for chemical digestion and release of nutrients. The teeth are vital to mastication, which breaks large bites of food down into smaller pieces that are easily swallowed. The stomach’s muscle contractions churn the food to expose all particles to the acid and digestive enzymes..

Question 1: One of the central themes in biology is how DNA, RNA, and proteins are related. Describe how genetic information flows between those types of molecules. Include the results of the processes of transcription and translation? ( Will Mark Brainliest if answered correctly. Do Not Repost Someone Else's Answer that is already on Brainly or any other websites please).
Answer:
Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA’s genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.
Answer:
DNA is the code that stores all our genetic information. When making a protein, DNA has to go through transcription and then translation. In transcription, an the genetic code of DNA is copied to mRNA, with the aid of an RNA polymerase protein which attaches single RNA units to the mRNA strand as the RNA polymerase moves on the DNA. Note that instead the letter T, RNA contains U. This occurs in the nucleus. The mRNA travels to the cytoplasm to a ribosome. The RNA also trims itself, removing parts that it does not need, and keeping parts for translation. The ribsomes use tRNA attached to amino acids to assemble the protein chain and translate the mRNA into proteins. As the amino acid chain, or polypeptide forms, a protein comes to be. However, there may be mutations, resulting from translation or transcription and sometimes these mutations may cause harmful affects.
How do i write a good hypothesis
Answer:
use "if...then...because"
Explanation:
a good way to write a hypothesis is using "if, then, because" statements because it fully explains your idea. you also need to make sure that your hypothesis is testable and realistic.
example/
Jimothy is testing if jazz music effects bee honey production. he writes this statement:
If jazz is played near a bee hive while producing honey, then the bees will produce more honey because the smooth music will raise their dopamine levels so that they become happier and therefore faster and more productive.
Answer:
I will write some tips in my explanation!
Explanation:
After formulating wh questions, it's time to form a hypothesis or an educated guess, but how do we do this?
First, you must gather the knowledge you already know; ad back it up with something that has happened like a study, article, etc
Example: It is a known fact that distilled water does not contain impurities, in fact, many distilled water companies boast about their water being clean and safe.
This will be the base of your hypothesis, and from here, just add the knowledge of which you know that can make up a well supported hypothesis, which you will then test.
Example:
It is a known fact that distilled water does not contain impurities, in fact, many distilled water companies boast about their water being clean and safe. Because distilled water is free of impurities, we can say that it cannot conduct electricity, but if we add salt to distilled water, the water will then be able to conduct electricity because...

Bacteria having cluster of flagella at both poles of the cell is known as Amphitrichous bacteria.
WHAT ARE AMPHITRICHOUS BACTERIA?Amphitrichous bacteria are types of bacteria that have flagellum on each of two opposite ends. An example of amphitrichous bacteria is Alcaligenes faecalis.
In this type of bacteria, only one flagellum functions at a time. This causes the bacterium to reverse course.

Why do sex-linked traits follow different patterns of inheritance than other traits ?
A. Females only have one X chromosome .
B. Males only have one X chromosome .
C. Males only carry recessive alleles .
D. Females only carry dominant alleles .

Which of the following human actions negatively affect the water cycle by increasing evaporation?
Answer: Hydroelectricity
Explanation: None Sorry
Burning of fossil fuels adversely impacts on the water cycle that adversely affect the climate on Earth.
Human activity such as the burning of fossil fuels in vehicles and burning of wood for cooking have adverse effect on the earth's atmosphere. This burning of fossil fuels increase the temperature of the earth leads to global warming.
Raising the Earth's temperature means that there is an increase of evaporation, melting of glaciers and sea ice which imbalance the water cycle leads to flood and drowning of coastal regions of the earth so we can conclude that burning of fossil fuels adversely impacts on the water cycle that adversely affect the climate on Earth.

They have unique combinations of chromosomes.
What are gametes?
In organisms that reproduce sexually, a gamete is a haploid cell that unites with another haploid cell during fertilization Gametes, commonly known as sex cells, are an organism's reproductive cells.
A female is any individual that generates the bigger kind of gamete—called an ovum—and a male creates the smaller type—called a sperm—in species that produce two morphologically distinct forms of gametes, and in which each individual produces only one type.
The flagellum, a tail-shaped feature that enables the cell to propel and move, is what makes sperm cells, or spermatozoa, tiny and motile. On the other hand, each egg cell or ovum is sizable and non-motile.
Therefore, They have unique combinations of chromosomes.

Applying the systems thinking techniques, outline the practical steps that can be taken to address drought
Some practical steps to address drought may include the implementation of efficient water usage techniques, the protection of vegetation, and the use of methods to retain moisture in the soil.
What is a drought?A drought is classified as the shortage or absence of water for a prolonged period of time in a region. These can be caused by a prolonged lack of rainfall.Other factors include poor water management and lack of vegetation.Methods to avoid droughts.The planting and protection of vegetation, primarily those adapted to dry environments, is important in preventing drought.Furthermore, the correct implementation of efficient water usage techniques can aid in preventing drought by limiting the amount of water that is wasted. Lastly, the use of mulch and other water retainers can be an effective method in keeping the soil moist and aids in the previous two methods.Therefore, we can confirm that the most effective ways to avoid droughts are to practice efficient water use so as to not waste water, to plant and protect vegetation, and to use mulch and other moisture-retaining methods to keep the soil from drying.
