Fermentation can only take place in an anaerobic environment because yeast is relatively anaerobic. When there is oxygen present, yeast engages in aerobic metabolism.

Yeast fermentation: When oxygen is present, yeast engages in aerobic respiration, converting carbohydrates (a source of sugar) into carbon dioxide and water. In the absence of oxygen, yeast ferments carbohydrates and produces carbon dioxide.

Through the process of electron transfer and oxygen, yeast mitochondria regenerate NAD+. Alcohol and CO2 are created during the fermentation process, which essentially only takes place in the absence of oxygen (resulting in carbonation). The roommate left the bucket open to the air, which provided the yeast with an ongoing supply of oxygen.

Answer:

What prevents these microorganisms from spreading resistance outside the laboratory is that they are modified to not survive outside the laboratory environment.

Explanation:

Antibiotic resistant microorganisms are very dangerous and unfavorable, as they leave living beings completely completely defenseless to their attacks. However, there are microorganisms that have been modified in the laboratory, as shown in the question above, and do not present any risk to living beings, even if they develop resistance. This is because the modification that these microorganisms received makes them not survive the environmental conditions outside the laboratory, which causes them to die if they leave the laboratory.

Cortisol helps the body deal with a stressful event by increasing blood sugar levels, suppressing the immune system, and suppressing the digestive system.

It is a steroid hormone produced by the adrenal glands that plays a vital role in the body's stress response. Here's a long answer for your better understanding: Cortisol, also known as the stress hormone, is produced in response to stressful situations. It activates the body's stress response system, allowing it to cope with the demands of the situation.

Cortisol has numerous functions in the body, including regulating blood sugar levels, suppressing the immune system, and suppressing the digestive system. In response to stress, cortisol is released from the adrenal glands, which are located above the kidneys. Cortisol increases blood sugar levels by stimulating the liver to release glucose into the bloodstream. This provides the body with a quick source of energy to deal with the stressful situation.

Sustainability is about maintaining the ecosystem diverse and productive, even attending the needs of production for humanity as well.

In order to do so, it's important to be careful about the disposal of any types of trash. So, avoiding to dispose of trash unnecessarily is really important, therefore A is correct. It is also important to avoid creating unnecessary trash, what happens when we chose to consume only water from plastic bottles, for example, instead of using reusable bottles. This means that B is also correct. Talking about not creating unnecessary trash, C is also correct, because it talks about avoiding single-use products. Also, avoiding the creation of unnecessary trash is related to E, because it's about avoiding excess packaging and/or avoid buying unnecessary items, reusing the same ones instead. Therefore, alternative D is incorrect, because while it talks about recycling it also incites the usage of plastic bags to dispose trash, which could be replaced by paper bags, for example.

Answer:

The correct answer is A. transplanted organs contain antigens that can trigger white blood cell activity

Explanation:

The body's immune system is designed to seek out and destroy any foreign object it finds in the body, such as a cold or flu virus - or a transplanted organ. The process of destruction of the transplanted organ is called rejection.Immunosuppressive drugs will be provided to prevent your immune system from damaging the transplanted organ. Organ transplants require the use of immunosuppressive drugs capable of controlling the immune response triggered by the presence of antigens foreign to the body itself. The group of immunosuppressants is made up of drugs indicated both in the prevention of rejection of the transplanted organ and in its reversal.

Different forms of genes can be called as alleles. Alleles are distinct variants of the same gene that control the same characteristic in an organism. Alleles are responsible for the diversity exhibited in many species.

An allele is a variant of the same gene with a different nucleotide sequence. Each allele codes for a distinct version of a gene or a different form of a gene product. For example, an eye colour gene may contain distinct alleles that result in blue, green, and brown eyes.

Alleles can be recessive, dominant, or codominant. Dominant alleles are more strongly expressed than recessive alleles, which means that the attribute associated with the dominant allele will be exhibited in the organism. Recessive alleles, on the other hand, will be expressed only if the dominant allele is absent. Both codominant alleles are expressed in the organism, resulting in a mixture of the two alleles.

Alleles might be homozygous or heterozygous as well. Homozygous alleles are identical alleles, whereas heterozygous alleles are distinct alleles.

Answer:

1. ATP - decrease

2.NADPH - decrease

3. sugars - decrease

And    True- Both ATP and NADPH are needed to make sugars.

Explanation:

Photosynthesis is a form of biosynthesis that produces glucose from the reactants;  it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.

Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII).  PS II absorbs and moves the reaction center with light energy.  

If PS II no longer works,  there will be less ATP, NADPH, (both used later on) and no sugars produced.

In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP).

The type of memory that shows the smallest decline in late adulthood is semantic memory.

Semantic memory refers to the memory system that stores general knowledge and facts about the world, such as vocabulary, concepts, and factual information. This type of memory is typically well-preserved in late adulthood compared to other types of memory, such as episodic memory (memory for specific events) and working memory (temporary storage and manipulation of information).

While there may be some age-related changes in semantic memory, research suggests that it remains relatively stable or shows only minor decline during late adulthood. This could be due to the fact that semantic memory relies on accumulated knowledge and experiences over a lifetime, which is less susceptible to age-related cognitive changes.

Assume that we have the dominant allele 'D' and the recessive allele 'd'. Lets make the example that the gene these encode for the fake disease called 'Fake Disease'. The recessive allele 'd' encodes for if you HAVE the disease. The dominant allele encodes for NOT having the disease. You get  passed on a version of this allele from both your parents and hence any individual will have the genotype of 'XX' (basically your genotype will be a combination of the two alleles dependent on what you got from your parents). ALSO for a recessive allele to be expressed in the phenotype (definition below) you need to have two copies of it because other wise the dominant allele 'D' will 'hide' the occurance of the single 'd' allele.

Homozygous (the prefix 'homo' means SAME).

Heterozygous (the prefix 'hetero' means DIFFERENT).

Genotype = the genes you have in your genome

Phenotype = what trait is expressed due to what genes you have

Homozygous dominant = SAME of the Dominant allele

- Genotype: DD (the two alleles you have are the same and are both the dominant alleles)

- Phenotype: Does not have Fake Disease (as the recessive 'd' allele encodes for this and the individual does not have two of the 'd' the disease is not expressed in the genotype)

Heterozygous = DIFFERENT alleles

- Genotype: Dd (you get one copy of each allele but both are different from each other)

- Phenotype:  Does not have Fake Disease (the dominant allele 'D' is what it is called 'dominant' it dominants over the recessive allele and will cover the expression of the recessive allele)

Homozygous Recessive = SAME of the Recessive Allele

- Genotype: dd

- Phenotype: Does have Fake Disease (having two recessive alleles of a trait means that it is expressed in the individual.

A tumor suppressor gene is a type of gene that helps regulate cell growth and division. These genes are also referred to as anti-oncogenes because their normal function is to prevent the development of cancer.

Tumor suppressor genes function to inhibit the uncontrolled growth of cells, which can lead to the formation of tumors. When a tumor suppressor gene is mutated or deleted, it can no longer perform its function, which can result in uncontrolled cell growth and the development of cancer. Apoptosis is a process of programmed cell death that occurs in multicellular organisms. Apoptosis is important for regulating cell growth and eliminating damaged or abnormal cells. Tumor suppressor genes can trigger apoptosis if they detect that a cell has suffered irreparable DNA damage or if a cell is growing uncontrollably.

Tumor suppressor genes function in several ways, including:

Regulating the cell cycle: Tumor suppressor genes help regulate the cell cycle by promoting the repair of damaged DNA or triggering cell death (apoptosis) if the DNA damage cannot be repaired.

Inhibiting cell proliferation: Tumor suppressor genes can also inhibit cell proliferation by preventing cells from dividing too rapidly or inappropriately.

Examples of tumor suppressor genes include:

TP53: This is one of the most well-known tumor suppressor genes. It encodes the p53 protein, which plays a critical role in regulating the cell cycle and triggering apoptosis in cells with DNA damage.

RB1: This gene encodes the retinoblastoma protein, which helps regulate the progression of cells through the cell cycle. Mutations in this gene can lead to the development of retinoblastoma and other types of cancer.

BRCA1 and BRCA2: These genes are involved in DNA repair and help prevent the development of breast and ovarian cancer. Mutations in these genes can lead to an increased risk of developing these types of cancer.

PTEN: This gene helps regulate cell growth and division by inhibiting a signaling pathway called the PI3K/AKT/mTOR pathway. Mutations in this gene can lead to the development of several types of cancer, including prostate, breast, and colorectal cancer.

The binding of galactose to GAL3 prevents GAL3 from associating with GAL80. This is a false statement.

The binding of Gal3 to the Gal80 monomer competes with Gal80 self-association. The Gal80 protein inhibits Gal4p-mediated transcription activation. So GAl3-GAL80 complex is formed not to prevent GAL4p. So the statement is false.  The binding of tryptophan to the repressor trpR allows the repressor to bind the operator. This is a true statement. Trp binds to its repressor so that it can bind to the operator. So the statement is true. The binding of cAMP to CAP when glucose is absent allows cAMP-CAP to bind the lac operon promoter and recruit RNA polymerase. This statement is true. In the absence of glucose, cAMP binds to the CAP so that CAP can bind to DNA. DNA-bound CAP helps RNA polymerase attach to the lac operon promoter. So the statement is true.
