2. Complete the statements about photosynthesis:
Glucose molecules are a product of _____ during_____ . After heterotrophs ingest food, glucose molecules are broken down during _____ in _____.
Answer:
Sex cells, haploid number of chromosomes, Diploid cell.
carbondioxide and water, photosynthesis, respiration, carbondioxide, water and energy.
Explanation:
The process of meiosis occurs during the division of sex cells and results in haploid number of chromosomes. During fertilization, gametes fuse with each other to form a diploid cell called a zygote. Glucose molecules are a product of two reactants known as carbondioxide and water during the process of photosynthesis. After heterotrophs take food, glucose molecules are broken down during respiration and as a result carbondioxide, water and energy in the form of ATP are produced.
The process of meiosis occurs during se-xual reproduction and results in haploid cells. To maintain the correct number of chromosomes in offspring, male and female gametes contain chromosomes as somatic cells. During fertilization, gametes fuse to form a diploid cell called a zygote.
Glucose molecules are a product of plants during photosynthesis. After heterotrophs ingest food, glucose molecules are broken down during glycolysis in the cytoplasm.

What is the direct result of this biological process?
a) duplication of genetic material
b) formation of mutations within cells
c) fertilization of an egg with a sperm
d) generating new combinations of alleles
Answer:
C
Explanation:
The direct result of this biological process is generating new combinations of alleles. The correct option is d.
What are chromosomes?Chromosomes are x shapes of hereditary material that are preset inside the nucleus. It is made up of DNA, genes, and proteins. Genetic characteristics of the genotype of an organism are unique because of unique genetic material, and this can be transferred to another generation from the first generation.
"Allele" is the word that we use to describe the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to lump the alleles into categories. When chromosomes cross over happens, the alleles changes and a new combination produces.
Therefore, the correct option is d. generating new combinations of alleles.

3. Forming Your Opinion Should antibiotics be
restricted? Are there some situations in which
such regulations would be more appropriate
than others?
Answer:
that depends the the kind of antibiotic it is. yes there some that may end up cause more problems then fixing them but there are some antibiotics that be very well within the human body. so if you ask me there should only be restraints on the ones that cause more problem. then they should find a way to better them and unrestricted them. we all known we have more than enough technology to do that. if we really wanted to we could make one antibiotic to cure everything no matter what it is.

A rock has been sent on a journey down through the layers of the Earth until it reaches the inner core. Explain what happens to the atoms in the rock as it moves through each layer.
Answer:
The rock components of the crust are slowly but constantly being changed from one form to another and the processes involved are summarized in the rock cycle (Figure 3.2). The rock cycle is driven by two forces: (1) Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust, and (2) the hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun.The rock cycle is still active on Earth because our core is hot enough to keep the mantle moving, our atmosphere is relatively thick, and we have liquid water. On some other planets or their satellites, such as the Moon, the rock cycle is virtually dead because the core is no longer hot enough to drive mantle convection and there is no atmosphere or liquid water.

pdf fluorescence of amphotericin b-deoxycholate (fungizone) monomers and aggregates and the effect of heat-treatment
The major therapy for systemic mycoses continues to be amphotericin B-deoxycholate (Fungizone). However, its usage is constrained by its toxicity, particularly renal impairment.
The polyene macrolide antifungal Amphotericin B, which is formed as micellar dispersion Fungizone (FZ), and its modified counterpart heat-treated Fungizone are both reported to have fluorescence excitation and emission spectra. The modulation of Amphotericin B aggregation state using sodium dodecyl sulfate or sodium deoxycholate surfactant indicates that the monomer and dimer states have distinct fluorescence spectra. It is seen that an excited dimer transfers energy to the monomer. The expected S₁ - S₀ fluorescence emission as well as anti-Kasha fluorescence emission from the S₂ state are both displayed by FZ and heat-treated FZ (HTFZ). The discoveries lay the foundation for upcoming fluorescence characterisation of FZ or HTFZ interactions with cell membranes.Learn more about the Amphotericin B with the help of the given link:

Human brain cells do not use fermentation.explain why a lack of oxygen for even a short period of time might result in the death of brain cells
Answer:
Brain cells are very sensitive and when they do not have oxygen they slowly start dying off which leads to brain damage.
Explanation:
Glycolysis produces important electrons and ATP which allow cellular respiration and fermentation to occur.
Brain produce ATP by glycolysis is the only process to generate energy, if anaerobic condition brain cells get dead.
What is fermentation?Since oxidative phosphorylation cannot make ATP in the absence of oxygen, glycolysis takes over as the cell's main source of ATP.
Because it supplies cells for the glyceraldehyde-3-phosphate dehydrogenase reaction, which comes before the steps that produce ATP, lactic acid fermentation is significant.
The adult brain only has a finite quantity of anaerobic glycolysis energy and time to sustain ion homeostasis and other vital activities before multiple events take place that cause brain cell damage and death.
Therefore, brain cells only depend on aerobic glycolysis for energy production.

Explanation:
what factors may lead to the accumulation of genetic differences between two physically separated populations
Factors that result in speciation encompass genetic differences, natural choice, geographical isolation, and mutation. Geographical isolation isn't a first-rate factor in the speciation of a self-pollinating plant species as pollination takes place among the reproductive organs of the identical flower.
In their separate niches, the two organizations go their very own evolutionary ways, collecting extraordinary gene mutations. Being subjected to distinct selective pressures, experiencing extraordinary historical activities, and eventually turning incapable of interbreeding they never come collectively again.
Speciation occurs when a set inside a species separates from other contributors of its species and develops its very own unique traits. The demands of a distinct environment or the traits of the contributors of the new institution will differentiate the brand new species from their ancestors.
