Stages of Human Gestation First trimester Second trimester Third trimester - Embryo develops - Organs begin to develop - (1) - Starts swallowing - Fat begins to develop - (2) - All organs are developed - Can hear and see - (3)
Answer:
Im doing the unit test and i believe the answer is C
Explanation:
It makes the most sense if you have studied.
The stages of human gestation and their time duration are given below:
First trimester: After conception to 12 weeks.Second trimester: Between 12 to 24 weeks. Third trimester: Between 24 to 40 weeks. What do you mean by Fertilization?Fertilization may be defined as a biological event that occurs by the fusion of male and female gametes successfully to produce a zygote.
The embryo develops after four to five weeks of conception which is the first trimester, organs initiate to develop by the end of the first trimester.
Swallowing is initiated at the beginning of the second trimester, and all organs are completely developed by the initiation of the third trimester. While all senses of hearing and seeing are developed by the middle of the third trimester.
Therefore, each trimester is characterized with its own functionality.

How did the insertion of a nucleotide in a DNA sequence result in a phenotypic change in an organism
Answer:
if the nucleotide insertion occurs within the coding region of a gene (frameshift mutation), then it will change the open reading frame (ORF) of the resulting protein and thus also will alter the phenotype of the individual
Explanation:
A mutation is any change in the DNA sequence of the genome of a cell/organism. A point mutation is a genetic mutation where a single nucleotide is inserted, deleted or changed from the original DNA sequence. The insertion of a single nucleotide in the coding region of a gene is called frameshift mutation since this nucleotide base shifts the way the DNA sequence is read. A frameshift mutation changes the meaning of the codons that follow the inserted nucleotide base and thereby protein function is generally lost, thereby also affecting the resulting phenotype associated with this protein.

if you remove all the water from an RBC, what's left besides a phospholipid bilayer cell/plasma membrane?)
Answer:
Salts, proteins and hormones.
Explanation:
Salts, proteins and hormones are the substances that are present in red blood cells. Plasma of the blood is composed of 90% water, salts, lipids and hormones. It is also rich in proteins such as albumin, immunoglobulins, clotting factors and fibrinogen. These substances are important parts of blood which made the blood to perform its function to transport nutrients in the body so after the removal of water, Salts, proteins and hormones are present in the red blood cell.
How quickly does the process of excretion occur in plants?
Explanation:
Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. ...

Look at the diagram below. It shows two solutions separated by a partially permeable membrane. Which number arrow shows the direction in which water molecules will move?
Answer:
Arrow no. 4
Explanation:
Water flows from a region of higher concentration to a region of lower concentration, i.e, osmosis.
Dilute solution means it has relatively less solute and more solvent, meaning more amount of water.
And just the opposite for concentrated solution.
So since the dilute solution has more water and concentrated solution has less, and water moves from a region of higher concentration to a region of lower concentration, option 4 is the correct answer.
During the osmosis process solvent is moved from a lower solute concentration to a higher solute concentration, hence arrow 4 defines the movement of water molecules.
What is osmosis?Osmosis is the process through which solvents move from a region of lower solute concentration to one of higher solute concentration across a semi-permeable membrane.
Water in the cell acts as a solvent and moves from lower solute concentration to higher solute concentration through a partially permeable membrane.
Conversely, in diffusion, molecules migrate from an area of greater concentration to regions of lower concentration without the need for a semi-permeable barrier.
Therefore diffusion of water molecules in the osmosis process from low solute concentration to high solute concentration, hence arrow 4 defines the movement of water molecules.

More than 100 years ago, Earth's atmosphere contained about 280 parts per million (ppm) of carbon dioxide. It is predicted that by the year 2050, the level of carbon dioxide in the atmosphere could reach 700 ppm, greatly increasing Earth's temperature. It has been suggested that growing more green plants would help to slow this increase. The best explanation for why increased numbers of plants would help is that plants
Answer: remove CO2 from the atmosphere during respiration
Explanation: I got the question right
Increased numbers of plants will reduce CO2 because plants use CO2 during photosynthesis.
What is photosynthesis?Photosynthesis converts light energy by phototrophs into chemical energy, then used for cellular power activities.Sugars, formed from water and carbon dioxide, store chemical energy.How do plants use CO2 in photosynthesis?Plants fix atmospheric CO2 to store energy as carbohydrates. In the dark reaction of photosynthesis, carbon dioxide is assimilated.CO2 is used in the carboxylation of ribulose bisphosphate during carbon fixation (RuBP). The reaction is catalyzed by the enzyme RuBisCO and is the first step in the Calvin cycle. It produces two molecules of 3-phosphoglyceric acid (3PGA), which is then reduced in a series of reactions to produce glucose, and RuBP is regenerated.Thus, we can conclude that during photosynthesis, plants use CO2 and reduce CO2 from the environment. Therefore, afforestation should be done.

"Grandpa, don't die!" Emma Abrams choked with deep conviction. "You mean everything to me. I can't live without you!" This was the part of the script where Emma was supposed to burst into real tears, yet her big blue eyes were like a desert. Emma tried to think of something despairing, like the time her toddling brother sliced his finger on a piece of broken glass while she was watching him, or the devastation she felt when learning that her cat had run away. These sad reflections did nothing to moisten her eyes. "Well, don't panic, Emma," she coached herself. "When it counts in the audition today, you'll cry real tears. You've just got to!"
It was difficult to study the script in the car with all of the bumps, turns, and sudden stops typical of trips into New York City, but Emma was determined to make sure that she had each line memorized word for word. She had studied every line nonstop since her agent had called with the good news. It was her first Broadway audition and her entire family had helped her to prepare. Her older sister helped her choreograph a dance, her father improvised with her by playing the part of Grandpa at the dinner table, and her little brother listened to her read her lines. No one was more constant in helping Emma realize her thespian ambitions than her mother, though. Mom was the one who accompanied Emma to her piano, voice, dance, and drama lessons each weekday after school. She went to every audition and performance with Emma, and Emma wished with all her heart that Mom was here with her now.
Emma appreciated her mother's constant companionship and support of her acting career. Her mother was always present backstage at the Dutch Apple Dinner Theater where Emma was currently starring in Annie on Friday and Saturday nights. Mom was the driving force behind her daughter's acting career, but she refused to drive in New York City. The big city frightened Mrs. Abrams and made her jittery. Since she was already nervous about Emma's big audition, Mrs. Abrams thought it best if she just stayed home. Emma tried to behave like a grown-up when her mother told her she wouldn't be going, but inside Emma felt panicky and alone.
Emma's father continued to navigate through the heavy traffic streaming into the city. As the skyline of New York City came into view, Emma started to cry. She knew she should have begged her mother to come with her but now it was too late! Her father looked into the rearview mirror and said, "Wow, honey! If you can do that during the audition, you're a shoo-in." He was genuinely impressed and didn't realize that her tears were real. Emma stared out the window, feeling sorry for herself.
Emma watched her dad hand his car keys to the parking attendant. They walked in silence for several blocks, with Emma holding her father's arm. She wanted to ask her father to come in to the audition with her, but she knew he'd be uncomfortable around a bunch of stage mothers. Emma soon found herself being escorted into a crowded lobby. She waved good-bye to her father and disappeared inside the theater.
When she emerged from the audition several hours later, Emma was exhausted but triumphant. "I don't ever want Mom to come to an audition where I have to cry again!" she declared as they left the theater together.
Knowing his daughter's flair for the dramatic, Mr. Abrams quickly said, "Now don't be angry with your mother because she couldn't come today, Emma. That's not fair."
Emma realized her father misunderstood her, so she explained that when she'd cried in the car earlier, it wasn't an act; she was genuinely upset that her mother wasn't with her. "When I went into the audition, all the other girls' mothers were there, but I was all alone. I was terrified without Mom there, so when they called on me to read my lines, I was on the verge of tears anyway. I just thought about how alone I felt without Mom there, and the tears came pouring down. It was perfect timing, and I think I just might get the part! Mom is the secret to my success." She bowed and curtsied to an imaginary audience, saying "Thank you, Thank you."
Mr. Abrams smiled and said, "I'm not sure, but I think that just this once, your mother will be extremely happy to hear that she made you cry."

Sequence differences in genes or genomes are used to determine organisms that are most related to each other based on evolution.
What does sequence difference mean?Sequence differences are differences which exists in the entire genome or a gene which code for proteis s whivh are related on function or structure in two organisms.
For proteins performing similar functions, organisms which have the least sequence differences are usually the most related organisms in an evolutionary sense whereas, organisms with the most sequence differences are the least related.
Therefore, sequence differences in genes are used to determine organisms that are most related to each other based on evolution.

HELP PLEASE! Choose 3 of the water quality indicators write a summary of what it is
Answer:
Explanation:
Dissolved oxygen (DO)
The DO test measures the amount of oxygen dissolved in the water. Oxygen is essential for both plants and animals, but high levels in water can be harmful to fish and other aquatic organisms.
Water temperature
Aquatic organisms are dependent on certain temperature ranges for optimal health. Temperature affects many other parameters in water, including dissolved oxygen, types of plants and animals present and the susceptibility of organisms to parasites, pollution and disease.
pH
A pH test measures the alkalinity or acidity of water. A pH of 7 is neutral, below 7 is acidic and above 7 is basic or alkaline. Acid rain, from auto exhaust or other pollutants, causes a drop in the pH. Pollution from accidental spills, agricultural runoff and sewer overflows can also change the pH.
Escherichia coli (E. coli)
E. coli is a fecal coliform bacteria that comes from human and animal waste. The Environmental Protection Agency uses E. coli measurements to determine whether fresh water is safe for recreation. Disease-causing bacteria, viruses and protozoans may be present in water that has elevated levels of E. coli. Levels of E. coli can increase during flooding. E. coli is measured in number of colony forming units. The EPA water quality standard for E. coli bacteria is 394 colony forming units per 100 mL.
