Answer:
Therefore, 98% of the US population have no alleles for PKU
Explanation:
The Hardy-Weinberg equilibrium states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
The Hardy-Weinberg equilibrium is expressed quantitatively using a mathematical equation known as the Hardy-Weinberg equation. the equation is given below:
p² + 2pq + q² = 1
also, p + q = 1
Given a pair of alleles, S and s with A dominant and a recessive
where p is the frequency of the dominant allele in the population,
q is the frequency of the recessive allele in the population,
p² represents the frequency of the (SS) dominant genotype,
q² represents the frequency of the (ss) recessive genotype,
2pq represents the frequency of the heterozygous genotype
From the given question,
q² = 1/10000 = 0.0001
q = 0.01
from p + q = 1
p = 1 - 0.01 = 0.99
p² = 0.98
Therefore, 98% of the US population have no alleles for PKU

The following chemical equation shows the combustion of ethane. Balance the equation by filling in the coefficients.
Answer:
2 C2H6 + 4 O2 → 2 C + 2 CO2 + 6 H2O
Explanation:
2 C2H6 + 4 O2 → 2 CO2 + 6 H2O is the balance equation for the combustion of ethane. In the question, the equation for combustion of methane is unbalanced i. e. C2H6 + O2 → CO2 + H2O so by putting coefficient 2 in front of ethane, 4 in front of oxygen, 2 in front of carbondioxide and 6 in front of water which can balance the unbalanced equation for combustion of ethane

You perform an experiment in which chromatin is isolated from sea urchin sperm cells and briefly digested with micrococcal nuclease. When the chromatin proteins are removed and the resulting purified DNA is analyzed by gel electrophoresis, you observe a series of DNA fragments that are multiples of 260 base pairs in length (that is, 260 bp, 520 bp, 780 bp, and so forth). a) Although these results differ somewhat from the typical results discussed in the chapter, explain why they still point to the likely existence of nucleosomes in this cell type. b) What can you conclude about the amount of DNA that is associated with each nucleosome
Answer:
a) DNA fragments associated with histone proteins are all multiple in length (i.e., 260 bp, 520 bp, 780 bp, etc), thereby suggesting the presence of a pattern of organization in the chromatin
b) it suggests that each unit of organization (ie, each nucleosome) consists of 260 bp associated with chromatin proteins
Explanation:
The nucleosome is considered as the basic unit of chromatin. A nucleosome consists of approximately two turns of DNA wrapped around a core of eight histone proteins (i.e., a histone octamer). The histone octamer consists of two copies of each of the histones H2A, H2B, H3, and H4. Moreover, the nucleosomes are connected together by linker DNA sequences which vary between 10 and 100 bp in length.

B. Water movement has caused longshore currents to erode the sediment from one end of this shoreline.
C. Water movement has caused this land to erode because there is no protection from strong waves.
D. Water movement has caused a build-up of various inlets to form a combination of tides and currents.
The impact that the movement of the water has in this area, is that the movement of the water has caused the erosion of this land because there is no protection against strong waves.
What causes marine erosion?Marine erosion, also called maritime erosion, is defined as “the process of wear, transport and sedimentation of rocks and coastal soils by erosive agents”. Fundamentally, it can be caused by the action of three factors:
WavesCurrents and Tides.With this information, we can conclude that the impact that the movement of water has in this area is that the movement of water has caused erosion of this land because there is no protection against strong waves.

In quiet breathing, muscular effort is used mainly in inspiration, and expiration is largely passive, due to elastic recoil of the lung. It results in a pattern change between expiratory and inspiratory flow. Explain changes you observed in the recordings you obtained. 1 pts Enter your answer here
Answer:
During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive as it depends on the inhalation.
The expiration occurs due to the elastic recoil that causes a decrease in volume. In this process, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle. During quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.
During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive basically depends on the inhalation because of elastic recoil that causes a decrease in volume.
During this, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle whereas quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.
What is Breathing?Breathing is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.

Glucose is a large molecule that is transported across the cell
membrane through a gated channel, a type of transport protein
used during what
diffusion
The type of transport protein used during glucose transportion across the cell membrane is facilitated diffusion.
Glucose is the main energetic substrate of the cell and requires a transporter protein in the cell membrane for its entry.
Proteins found on the surface of the membrane intervene in facilitated diffusion, which, when they make contact with the molecules, bind to them and allow their entry.
This route is used by molecules that are larger in size, with properties other than the membrane (polar), or are charged and do not cross the membrane freely; for example glucose.
The transport of glucose across the cell membrane is carried out by two families of membrane proteins:
Sodium-coupled glucose transporters are expressed mainly in epithelia that are responsible for the absorption and reabsorption of nutrients.Glucose transporter (GLUT) are expressed in all cells of the body and allow glucose to move from one compartment to another.
Therefore, we can conclude that glucose enters cells through facilitating transport systems, glucose transporter are expressed in all tissues of the organism and transport glucose through its concentration gradient, hence the name of facilitated diffusion.

Food webs in ecosystems become very complicated very fast. Explain why.
Answer:
Food webs are more complex than food chains, yet equally as useful in understanding the processes of ecological communities. A food web shows the flow of nutrients between different types of organisms which can help us understand the energy transfer as described before.
Explanation:
Food webs in an ecosystem involves the combination of two or more food
chains. This involves all the relationship an organism has with the others.
This makes the food web complex.
Food webs have different types of organisms present which ranges from
plants which are regarded as the primary producers to animals such as Lion
which can be regarded as a Secondary/tertiary consumer in the ecosystem.
The occasional change in the geography and seasons in the ecosystem
also makes it very complex as some animals exhibit different traits when
subjected to certain conditions. This makes analysis of energy flow and relationship sketchy to determine.
