Sexual reproduction is a process in which two gametes or haploid cells (with only one set of chromosomes) unite to form a diploid cell (with two sets of chromosomes). The diploid cell obtained has the ability to undergo mitosis to divide numerous times to form an individual.

In contrast, asexual reproduction does not use gametes and has more diverse mechanisms depending on the organism we are talking about.

Therefore, the answer is sexual reproduction.

Here are some uses of biotechnology in the production of washing powders:

Enzymes: Enzymes are commonly used in washing powders to enhance the cleaning efficiency and remove various types of stains.  Proteases, amylases, lipases, and cellulases are examples of enzymes used in washing powders. These enzymes break down protein-based, starch-based, lipid-based, and cellulose-based stains, respectively, into smaller fragments, making them easier to remove during the washing process.

Bio-surfactants: Surfactants are essential components of washing powders as they help to remove dirt and oil from fabrics. Biotechnology allows for the development of bio-surfactants, which are surfactants derived from biological sources, such as bacteria or yeast. These bio-surfactants are more environmentally friendly than traditional surfactants as they are biodegradable and have lower ecological impact.

Microbial Strains: Biotechnology can be used to isolate, characterize, and optimize microbial strains that produce enzymes or bio-surfactants. Microorganisms, such as bacteria and fungi, can be engineered or selected for their ability to produce specific compounds that enhance the cleaning performance of washing powders.

Genetic Modification: Genetic modification techniques can be employed to enhance the properties of microorganisms used in the production of enzymes or bio-surfactants. This allows for the creation of microorganisms with improved characteristics, such as increased enzyme activity or enhanced stability under varying conditions.

Fermentation Processes: Biotechnology facilitates the use of fermentation processes to produce enzymes and bio-surfactants at a large scale. Fermentation involves the controlled growth of microorganisms in bioreactors, where they produce enzymes or bio-surfactants through metabolic processes. This enables the efficient and cost-effective production of these ingredients for use in washing powders.

Explanation:

If a bacterium can reproduce quickly by splitting into two cells, then statement B. They have the same amount of genetic material and are identical BEST describes their genetic make-up of the resulting bacteria.

Asexual cell division processes such as binary fission in bacteria are well known to produce genetically identical bacteria from a parental cell in a similar manner to mitosis in eukaryotic cells.

Therefore, with this data, we can see that asexual cell division processes are capable of generating identical cells with the same genetic material.

Explanation:

An environmental factor like a fire can have a significant impact on an ecosystem. For example, consider a forest ecosystem where a fire breaks out. The fire can directly impact the vegetation and animal populations in the following ways:Loss of Vegetation: The fire can burn through the vegetation, resulting in a significant loss of trees, shrubs, and other plants. This can lead to changes in the composition of the ecosystem and the loss of habitats for animals that depend on the vegetation.Soil Nutrients: The fire can alter the soil nutrients by burning up the organic matter, resulting in a loss of nutrients that the plants need to grow. This can affect the growth of new vegetation and the ability of the ecosystem to recover.Animal Population: The fire can directly impact animal populations by killing animals, destroying habitats, and reducing the availability of food and water. The animals that survive the fire may face competition for resources as they seek out new habitats.Water Quality: The fire can affect the water quality in the ecosystem by increasing sedimentation and runoff, which can lead to increased erosion and pollution of water bodies.Ecological Succession: After a fire, the ecosystem undergoes a process called ecological succession, where the vegetation and animal populations gradually recover and change over time. This can lead to long-term changes in the ecosystem structure and composition.Overall, a fire can have significant impacts on an ecosystem, altering the vegetation, soil, animal populations, and water quality, and leading to long-term changes in the ecosystem structure and function.

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.

Down syndrome is caused by non-disjunction during meiotic division. Option A) In trisomy 21, an error during meiosis results in three copies of chromosome 21, leading to developmental deficits.

Non-disjunction is the proper separation failure of chromosomes during anaphase I or II of the meiotic division.

This mistake in segregation results in the production of gametes containing a greater or lesser number of chromosomes than is found in a normal cell. Consequently, the individual may develop a trisomy or monosomy.

Non-disjunction produces aneuploidy, which is a disbalance in the number of cell chromosome copies.

If  non-disjunction occurs in meiosis II.

However, if non-disjunction occurs in meiosis I, all the produced gametes will be chromosomally abnormal.

Nullysomies generate final monosomy after fertilization.

Diploid gametes produce final trisomy after fertilization.

Non-disjunction is a cause of various abnormal medical conditions, including Down syndrome and Turner syndrome.

Down syndrome is a genetic disorder that produces extra genetic material in chromosome 21. Affected individuals express a typical physical appearance, intellectual disability, and developmental delays.

Option A) In trisomy 21, an error during meiosis results in three copies of chromosome 21, leading to developmental deficits.

Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.

The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.

Assuming a diallelic gene,

Allelic frequencies

Genotypic frequencies

The addition of the allelic frequencies equals 1

p + q = 1.

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

In the exposed example,

Alleles          Frequencies

Genotypes

We need to get the number of animals expressing each genotype and phenotype. To do it, we just need to use allelic frequencies and calculate  genotypic frequencies (p², 2pq, and q²), and then multiply these values by the total number of animals (N = 175).

Genotypic and Phenotypic frequencies

F(S^AS^A) = p² = 0.6² = 0.36

F(S^AS^B) = 2pq = 2 x 0.6 x 0.4 = 0.48

F(S^BS^B) = q² = 0.4² = 0.16
