Answer:
Karotyping is a chromosomal analysis. It can be used to look for diseases caused by irregularities in the chromosomes, such as Down syndrome.
Explanation:
Karotyping is a chromosomal analysis of the chromosomal constitution of the nucleus of a cell, which is equal to the complete chromosomal makeup of a person. The chromosomes of each species have a certain structure both in size, shape and their own band when they are stained in the laboratory. This allows them to be identified as well as to know if all the genetic information is in the correct order. In addition to numerical abnormalities in chromosomes, structural alterations mean that certain chromosomal regions can be duplicated or even absent. This gain or loss of genetic material has highly varied consequences depending on the genes involved. Another type of structural alterations are translocations and inversions. The karyotype can be studied in search of diseases caused by irregularities in the chromosomes, such as Down syndrome. It also helps to identify problems that a baby conceived through assisted reproduction may have when it is born, by extracting the karyotype that is found in the amniotic fluid of the embryo.
What will pair with adenine?
In DNA base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine. Adenine is also one of the bases in RNA. There it always pairs with uracil (U). The base pairs in RNA are therefore A-U and G-C.
4. Which of the following is NOT true of the digestive system? a. The stomach contains acids to break down food b. Digestion begins with enzymes in the stomach c. The large intestine absorbs water from the digestion of nutrients d. The small intestine does most of the absorption of nutrients
Answer:
B. Digestion begins with enzymes in the stomach
Explanation:
The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.

The following is a growth curve of bacteria. What type of growth curve is pictured? A) linear growth B) logistic growth C) exponential growth
Answer:
C) exponential growth
In the given figure, exponential growth curve is pictured.
What is exponential growth?It is the pattern of data, which demonstrates greater enhancements with passing time, giving rise to a curve of an exponential function. During the growth cycle of bacteria, the cells of bacteria goes through different phases, that is:
Lag phaseExponential phaseStationary phaseDeath phaseIn the case of bacteria, the cells enter the log or the exponential phase after the lag phase. This is the time when the cells get differentiate by the process of binary fission and double in numbers after each generation time.
In this pattern of growth, the metabolic activity is high as RNA, DNA, the components of the cell wall, and other substances essential for growth are generated for differentiation.
Thus, the pattern of growth demonstrated in the given figure is exponential growth.

Most scientists theorize that prokaryotic cells evolved before eukaryotic cells based on
which observation?
Eukaryotic cells are smaller.
O Prokaryotic cells are the only ones with cell walls.
Prokaryotic cells are less complex,
Eukaryotic cells have ribosomes.
Answer: I'm not 100% sure but it is either prokaryotic cells are the only ones with cell walls or prokaryotic cells are less complex because their both true about prokaryotic cells
Explanation:
Four students provide their teacher with an explanation of why photosynthesis is considered a chemical change. Luke: Photosynthesis is considered a chemical change because the CO2 molecules disappear and the O2 molecules reappear. Jackie: I know that photosynthesis is a chemical change because all of the reactants undergo a state of matter change and are all present as a product. Tara: Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change. Skyler: Photosynthesis is a chemical change because solar energy is required. Which student provides the best explanation of why photosynthesis is a chemical change
Answer:
The best explanation was provided by the student Tara who said: "Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change".
Explanation:
A chemical change is one which is not easily reversible and which results in the formation of new subsatances.
For example, in photosynthesis,a new substance, glucose is formed from the original substansubstances, carbon dioxide and water. Also, the reverse process of the formation of carbon dioxide and water from glucose is not easily obtained in plants.
From explanations provided by the students :
Luke does not give any explanation of the process but only an observation
Jackie's explanation does not state the main reason why a chemical change differs from a physical one.
Tara, gives the best explanation as the reason why a change that occcured is a chemical change is clearly stated.
Skyler does not state the main reason why photosynthesismis a chemical change as well, because even physical changes like evaporation of water involves solar energy.

4. Analyze: Compare the offspring traits to the parent traits.
A. Which traits were passed from parents to offspring? __________________________
B. Which traits were not passed down? ______________________________________
Traits that are not passed down (not inherited) are called acquired traits.
Answer: 4a. The transmission of characteristics from parents to offspring is called heredity, and the characteristics that are inherited can be predicted. 4b. An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence. Acquired traits are synonymous with acquired characteristics.

may this helps you

It is true that photosynthesis is an important part of the carbon cycle. The correct option is A.
What is the role of photosynthesis in carbon cycle?Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into oxygen and sugar energy.
Plants absorb carbon dioxide and sunlight during photosynthesis to produce fuel glucose and other sugars for plant structure construction. The fast (biological) carbon cycle is built on this process.
The carbon cycle includes cellular respiration and photosynthesis. The carbon cycle refers to the processes by which carbon is recycled in the biosphere.
While on the other hand cellular respiration emits carbon dioxide into the environment, photosynthesis absorbs carbon dioxide.
Carbon dioxide is removed from the atmosphere by photosynthesis and replaced by cellular respiration. Photosynthesis takes oxygen from the atmosphere and cellular respiration replenishes it.
Thus, the correct option is A.

Explain what would happen to a person if they eat/drink something that their body does not have an Enzyme for?
Answer:
People with lactose intolerance may have a variety of symptoms. It all depends on how much dairy or how many milk-containing foods the person eats and how little lactase the body produces.
Usually within 30 minutes to 2 hours after eating, someone with lactose intolerance will experience nausea, stomach cramps, bloating, gas, and diarrhea. This can be unpleasant, not to mention embarrassing if you're at school or out with friends.
Because many people may think they're lactose intolerant when they really aren't, it helps to see a doctor who can diagnose the condition correctly and advise you on ways to manage it.

Compare and contrast the location and function of ribosomes in prokaryotic and eukaryotic cells.
Answer:
Explanation:
In eukaryotic cells, ribosomes are found in the cytosol of a cell, the mRNA , endoplasmic reticulum and also the matrix of the mitochondria. They are large molecules that catalyzes the synthesis of proteins, which is called translation. The ribosome choose tRNA and covalently links the amino acids into a polypeptide chain.
In prokaryotes, it can be found in cystosol and it help translate genetic code into protein.
