Explanation:

a) Two factors they need to keep the same in their investigation are the type of plant they are using and the amount of water and light they give each plant.

b) The factor they change is the amount of water and light they give to each plant.

To get their results, they measure the growth of each plant over a set period of time. They may also measure other factors such as the number of leaves, the height of the plant, or the color of the leaves to determine the overall health of the plant.

a) In their investigation, the students need to keep two factors the same:

1. Temperature: They must maintain a constant temperature of 25°C throughout the experiment.

2. Control substances: They need to keep the substances used in the control situation the same.

b) The factor they change is:

The students change the conditions related to the pH of the reaction mixture, the amount of yeast added, and the type of sugar used.

a) In their investigation, the students need to keep two factors the same:

1. Temperature: They must maintain a constant temperature of 25°C throughout the experiment. This ensures that any changes in the rate of fermentation are solely attributed to the variables they are testing.

2. Control substances: They need to keep the substances used in the control situation the same. This includes using 25 ml of buffer pH 7, 2 grams of sucrose, and 2 grams of yeast. Keeping these constant allows for a baseline comparison against the experimental conditions.

b) The factor they change is:

The variable being tested: The students change the conditions related to the pH of the reaction mixture, the amount of yeast added, and the type of sugar used. These variables are altered to observe their effect on the rate of fermentation.

To obtain their results, the students measure the pressure generated during the fermentation process. They use a Vernier Equipment Pressure sensor connected to a LabPro interface to record the pressure values over time.

By collecting and analyzing the pressure data, they can assess the rate of fermentation under different experimental conditions. The pressure readings indicate the gas produced as a byproduct of fermentation, providing a quantitative measure of the fermentation rate.

This allows the students to determine the optimal conditions for the new fermentation process to be used at the local bakery.

Explanation:

In geology, petrifaction or petrification is the original material and the filling of the original pore spaces with minerals. Petrified wood typifies this process, but all organisms, from bacteria to vertebrates, can become petrified. Petrification (petros means stone) occurs when the organic matter is completely replaced by minerals and the fossil is turned to stone. This generally occurs by filling the pores of the tissue, and inter and intra cellular spaces with minerals, then dissolving the organic matter and replacing it with minerals. Researchers at UCLA and the University of Wisconsin–Madison have confirmed that microscopic fossils discovered in a nearly 3.5 billion-year-old piece of rock in Western Australia are the oldest fossils ever found and indeed the earliest direct evidence of life on Earth.

When examining evolutionary relationships, taxonomists strive to classify organisms according to shared common ancestors.

Evolution is a process in which changes occur in living beings over time, often leading to the emergence of new species. These modifications are passed on to descendants, which is why many define evolution as descent with modification as well.

With this information, we can conclude that The evolutionary relationships of organisms can be represented by phylogenetic trees (or phylogenies), which are tree-shaped branching diagrams that show the ancestral relationships between species.

Explanation:  

Before gametes are formed, during anaphase sister chromatids separate and migrate to the poles. Following the low of segregation and independent assortment, alleles from the same trait and from different traits separate independently from each other. During this separation, there might be different gene combinations according to their position in the chromosome, the occurrence of crossing over, and the destiny of each chromatid.

a. Genotype YyRr, if Y and R are on different chromosomes

Genes are located in two different chromosomes, which means that there might be four possible gametes.

b. Genotype YyRr, if dominant Y and R are on the same chromosome, no crossing over

Genes are located in the same chromosome, which means that there might be two possible gametes.

c. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over

Genes are located in the same chromosome, which means that there might be two possible gametes.

d. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over

The fact that there is 50% crossing over means that these genes are not linked. There are four possible gametes

The brain and spinal cord are part of the central nervous system.

The electrical charges that act as nervous signals are called action potentials or nerve impulses.

Jellyfish do not have a brain. Instead, their nervous system is called a nerve net.

After nervous systems began to develop in bilaterally symmetric animals, some developed ventral nerve cords, while chordates developed dorsal nerve cords.

Skeletons that allow for movement by using muscles and squeezing liquid to change the body shape are called hydrostatic skeletons.

Exoskeletons do not grow with arthropods, and so occasionally must be shed and regrown from chitin.

Muscles move endo- and exoskeletons by contracting and relaxing.

Fertilization is the joining of two gametes called sperm and egg.

A fish that lays her eggs in a cluster is initiating cluster or mass fertilization.

Describe three different strategies used by three different animals to thermoregulate.

If you see a snake coiled up in a sunny patch of grass, what can you probably conclude about the type of thermoregulator it is. Why?

If you see a snake coiled up in a sunny patch of grass, you can probably conclude that the snake is an ectotherm. Ectotherms rely on external heat sources, such as the sun, to regulate their body temperature. By basking in the sun, the snake absorbs heat, which helps raise its body temperature to a suitable level for proper physiological functioning.

Answer:

1. central

2. action potential

3. nerve net

4. dorsal

5. hydrostatic

6. Exoskeletons

7. contraction/contracting

8. Fertilization

9. external fertilization

10. Eggs

11. Animals with fur thermoregulate by panting. Winged birds will flap against their mouths/heads to dissipate heat. Humans will produce sweat to evaporatively cool. Polar bears have developed blubber. Bears drop body temperatures during hibernation.

12. Seeing a snake using the warmth of the sun leads us to conclude that it is likely a thermo conformer that cannot produce its own body heat.

When a protein is produced and expelled by the cell, these events take place in the following order: Within the nucleus, DNA first undergoes transcription into RNA.

The translation of this RNA into a polypeptide chain occurs when it binds to ribosomes in the cytoplasm. The endoplasmic reticulum (ER), where it is altered and folded into its functional form, receives the polypeptide once it has been carried there.

The Golgi apparatus is where the protein is further processed and packaged into vesicles once it has been created. Once at the cell membrane, these vesicles are exocytosed, releasing the protein into the extracellular space.

The acceleration of the car is 2 m/s².

The average velocity of the car is 2 m/s.

The equation acceleration = (final velocity - beginning velocity) / time can be used.

Given:

Initial velocity (u) = 0 m/s (since the car starts from rest)

Final velocity (v) = 20 m/s

Time (t) = 10 s

Using the formula, we can substitute the values:

acceleration = (20 m/s - 0 m/s) / 10 s

acceleration = 20 m/s / 10 s

acceleration = 2 m/s²

Therefore, the acceleration of the car is 2 m/s².

You can use the following equation to determine the average velocity: average velocity = total displacement / total time.

The initial position and the final position are identical since the automobile begins at rest. As a result, the displacement and the ultimate position are equal.

Given:

Displacement = 20 m

Time (t) = 10 s

Using the formula, we can substitute the values:

average velocity = 20 m / 10 s

average velocity = 2 m/s

Therefore, the average velocity of the car is 2 m/s.

The author of the story below uses figurative language to reveal that the narrator feels unnoticed by Natalie (option D)

Figurative language deviates from the usual word order and meaning in order to convey a complex meaning, vivid writing, clarity, or an emotive comparison. By using a regular sentence, it refers to something without actually declaring it.

Figurative language, which is frequently used in both literature and everyday speech, is present in many phrases. Figurative language asks the reader or listener to consider the meaning of something (a "vehicle") in the context of other ideas, actions, or visuals (a "tenor").

Understanding figurative language is necessary to read the Management Discussion and Analysis (MD&A), where management may use a metaphor to clarify complex ideas or the direction the organization is taking.

The question is incomplete, it should be:

My sister Natalie wanted to grow up in seconds and not in years. I was left behind to catch up in real time. Only two years apart, I also felt decades away from her. Natalie wanted privacy, personal room, and mother’s pretty possessions at ten. I longed for her cuddles, which she only dispensed when she had upset me and was sorry. I loved my big sister with every ounce of my being though she felt weighed down by my displays of affection.

“When I was your age, your aunt Jen and I weren’t close,” our mother confessed. “Now, we can’t get enough of each other. Your grandparents are really old, and we share our worries and responsibilities, you know.”

I wasn’t ready to think about that—my beautiful mother being frail or my towering father using a cane. I suspected Natalie would be ahead in the care arrangements and that I would try to play catch-up. I wondered if I would always be just a shadow in Natalie’s life until the day I caught her sobbing in the hallway.

“You didn’t see anything,” Natalie said between sobs and rushed to her room, which she didn’t seal with a locked door.

Entering her neat room, which was a furniture catalog, was a privilege. The veneer of the green curtains added a layer of beauty to the windows. Except for crumbled tissues in the trashcan, nothing seemed unkempt. What had been bothering my perfect sister?

“What’s wrong?” I asked and sat on the edge of the bed to take up the smallest possible space. Then, I spotted a broken friendship bracelet by the night lamp. How could I have not noticed before? Carly hadn’t come over in months. Natalie wasn’t on the phone every free minute of Saturday and Sunday. I had been buried in books and band practice and failed to see my big sister’s loneliness. “Do you want to watch Zombie Cheer together? We don’t have to talk. We can just be…together.”

Natalie lunged at me to hold me tight and wailed until my hair was damp. I let her. Then, she dried her face with tissues and took me by the hand to the living room. Mother had already set up two big bowls of popcorn, which looked like heaps of comfort. Mother always knew everything.
