Answer:
d
Explanation:
the population is evolving
Allele frequency is the probability of the gene in a particular population. The consistently changing allele frequency in a population depicts the process of evolution. Thus, option D is correct.
What is evolution?Evolution is the modification in the transitional or the expansion of the inherited characters passed from the parent to the offspring and successive generations over time through reproductive methods.
The allele or the gene frequency defines the evolutionary pattern as the alleles carry and express the characteristics that were passed. Due to environmental changes, the alleles can get modified for better adaptation.
This adaptation and natural selection allow the organism to evolve from the pre-existing species to adapt and with better traits that enable their survival.
Therefore, option D. the changing frequency depicts the evolving population.

affect(s) the fluidity of the cell membrane by limiting the movement of phospholipids.
A. Glycoproteins
B. Carbohydrates
C. Fatty Acids
D. Cholesterol
Answer:
The fluidity of the membrane is defined as the viscosity of the lipid bilayer, such that it can affect the inward and outward movement of the biomolecules. The correct option is Cholesterol. It affects fluidity by either decreasing or increasing. It is the most important factor for the regulation of fluidity.
Explanation:
Cholesterol affects the cell membrane's fluidity because these molecules are randomly distributed along the lipid bilayer. The cholesterol functions to hold the phospholipid together, such that it does not create large spaces and allow the movement of unwanted particles.
The cholesterol plays a crucial role in holding the phospholipids, as in the absence of cholesterols, lipid bilayer will separate and allow diffusion of unwanted molecules.
Glycoproteins are the molecules in which proteins having glycans are linked to amino acid side chains. These molecules play a crucial role in the recognition and adhesion of the cells.
Carbohydrates are linked to lipids, known as glycolipids, which are a vital part of cell membranes. These molecules function to address the loci but do not affect the fluidity of the cell membrane.
Fatty acids can be unsaturated or saturated, which consists of multiple or single bonds. These bonds result in fluidity.

If two parents are contributing genetic material to their offspring, why don’t the genes and chromosomes double in each generation?
Chromosomes and genes do not double in each generation in se-xual reproduction because they are usually halved before being donated to offspring.
What is meiosis?Meiosis is a reductional division involving s-ex cells. Meiosis happens prior to se-xual reproduction.
In other words, the halving of chromosomes takes place during the formation of gametes. Thus, gametes usually carry half of the chromosome and only a copy of each gene of the parents.
When two gametes combine to result in a zygote, their chromosomes and genes also pair up to arrive at a normal number of chromosomes and genes.

What challenges do you envision that would hinder the progress of a flipped
classroom?
Answer:
Explanation:
Need to Know. How are you creating a need to know the content that is recorded? Just because I record something, or use a recorded material, does not mean that my students will want to watch, nor see the relevance in watching it.
Engaging Models. One of the best way to create the "need to know" is to use a pedagogical model that demands this. Whether project-based learning (PBL), game-based learning (GBL), Understanding by Design (UbD), or authentic literacy, find an effective model to institute in your classroom.
Technology. What technology do you have to support the flipped classroom? What technology gaps exist that might hinder it? Since the flipped classroom is about recorded video, then obviously students would need the technology to do this.
Reflection. Every time you have students watch a video, just like you would with any instruction

Cellular respiration transforms glucose and oxygen into carbon dioxide, water, and energy.
C6H12O6 + 602 = 6CO2 + ?H20 + Energy
Based on the law of conservation of matter what is the missing coefficient for water?
1. 6
2. 8
3. 4
4. 2
Answer:
6
Explanation:
The left side of the equation has 6 molucules.
C6H1206
The equation must be balanced so it must be 6 for the coeffciet of water.
On the basis of the law of conservation of matter, the missing coefficient for water is 6 in the process of cellular respiration. Thus, the correct option for this question is 1.
What is Cellular respiration?Cellular respiration may be defined as a chemical process through which the breakdown of food in the cell occurs with the liberation of energy in the form of ATP. It involves the series of chemical reactions by which living organisms produce energy through the oxidation of organic substances.
The entire process of cellular respiration transforms glucose and oxygen into carbon dioxide, water, and energy. According to the process of balancing chemical equations, the number of the hydrogen atom is equal to 12, then the water molecule comprises H20, so there is a need of inserting 6 to complete the missing coefficient for water.
Therefore, the missing coefficient for water is 6, thus, the correct option for this question is 1.
