Answer:
Yes.
Explanation:
Yes, the fungicides harm bee development by causing changes in behavior, immune health, and reproduction etc. For verifying this hypothesis, we have to take two environments, in one environment fungicides are applied to the plants while on the other environment, there is no fungicide applied to the plants. Th result shows that the bees are affected and act abnormal where fungicides are applied as compared to those bees which are normal in behaviour and other features.

What are three techniques that can be used to show that the electron transport chain is found on the matrix side of the inner mitochondrial membrane. Select all that apply.
Answer:
Explanation:
Step 1: Generating a Proton Motive Force
The hydrogen carriers (NADH and FADH2) are oxidised and release high energy electrons and protons
The electrons are transferred to the electron transport chain, which consists of several transmembrane carrier proteins
As electrons pass through the chain, they lose energy – which is used by the chain to pump protons (H+ ions) from the matrix
The accumulation of H+ ions within the intermembrane space creates an electrochemical gradient (or a proton motive force)
Step Two: ATP Synthesis via Chemiosmosis
The proton motive force will cause H+ ions to move down their electrochemical gradient and diffuse back into matrix
This diffusion of protons is called chemiosmosis and is facilitated by the transmembrane enzyme ATP synthase
As the H+ ions move through ATP synthase they trigger the molecular rotation of the enzyme, synthesising ATP
Step Three: Reduction of Oxygen
In order for the electron transport chain to continue functioning, the de-energised electrons must be removed
Oxygen acts as the final electron acceptor, removing the de-energised electrons to prevent the chain from becoming blocked
Oxygen also binds with free protons in the matrix to form water – removing matrix protons maintains the hydrogen gradient
In the absence of oxygen, hydrogen carriers cannot transfer energised electrons to the chain and ATP production is halted

Modelizar un ecosistema colocando los niveles tróficos y las relaciones en la red alimentaria
Answer:
Ejemplo ecosistema y su cadena trófica:
- Ecosistema: llanura (campo de maíz)
- Productor primario: plantas de maíz
- Consumidor primario: Ratones
- Consumidor secundario: Aves rapaces
- Microorganismo descomponedor: bacterias
Explanation:
En una cadena trófica o cadena alimentaria de un ecosistema, cada nivel obtiene la energía necesaria para sustentar la vida a partir del nivel inmediatamente anterior, mientras que los productores primarios son aquellos organismos que hacen ingresar la energía al ecosistema. Por otra parte, los descomponedores son organismos que se alimentan de los restos de animales y plantas, mediante su descomposición, obteniendo de ellos energía y materia hasta transformarlos en materia inorgánica. En el ejemplo arriba citado, las plantas de maíz representan los productores primarios los cuales producen energía y materia orgánica requerida para sustentar el ecosistema mediante el proceso de fotosíntesis. En segundo lugar, los ratones, como así también otros organismos herbívoros, representan los consumidores primarios los cuales conforman el segundo nivel trófico de la cadena alimentaria. En tercer lugar, los animales carnívoros que se alimentan de consumidores primarios (como por ejemplo, aves rapaces) representan el tercer nivel trófico, y así sucesivamente niveles superiores en el caso que existan depredadores mayores en el ecosistema. Finalmente, bacterias y otros organismos (por ejemplo, hongos, lombrices, algunos insectos, etc) representan los descomponedores los cuales se alimentan de restos orgánicos en descomposición, transformándolos de este modo en compuestos inorgánicos que ingresan nuevamente al ecosistema.

hope it helps you!!!A penicillin reaction is a life-threatening event. In those who are allergic to penicillin, the drug acts as a __________ that binds to blood proteins, causing a strong immune response.
Answer:
A penicillin reaction is a life-threatening event. In those who are allergic to penicillin, the drug acts as a hapten that binds to blood proteins, causing a strong immune response.
Explanation:
Low molecular weight chemicals can bind to antibodies, but cannot activate B lymphocytes by themselves (they are not immunogenic). To generate specific antibodies to these small chemicals, immunologists typically bind them to macromolecules prior to immunization. In these cases, the chemical is called a hapten. Penicillin G is a typical hapten that tends to covalently bind to lysine residues both in solution and in protein-bound cells. Penicillin is a drug that behaves as a hapten, since the beta-lactam ring under physiological conditions opens and reacts with the lysine residues of proteins, forming a complex that is the main antigenic determinant of penicillin and other beta-lactams and is capable of to stimulate responses mediated by antibodies or by T cells.
What is a group of microscopic unicellular organisms
Use the coordinates of the labeled point to find the point-slope equation of
the line
-5
5
-5
(3.-5)
O A. y+ 5 = -3(x - 3)
B. y- 5 = -3(x+3)
C. y + 5 = 3(x+3)
O D. Y-3 - (x+5)
Answer:
A. y + 5 = -3(x - 3)
Explanation:
Given the following data;
Points on the graph (x1, y1) = (3, -5)
Points on the graph (x2, y2) = (0, 4)
First of all, we would determine the slope of the equation of line;
Mathematically, the slope of a line is given by the formula;
[tex] Slope, \ m = \frac {Change \; in \; y-axis}{Change \; in \; x-axis} [/tex]
[tex] Slope, \ m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the formula, we have;
[tex] Slope, \ m = \frac {4 - (-5)}{0 - 3} [/tex]
[tex] Slope, \ m = \frac {4 + 5}{0 - 3} [/tex]
[tex] Slope, \ m = \frac {9}{-3} [/tex]
Slope, m = -3
Next, to find the point-slope equation of the line, we would use the following formula;
y - y1 = m(x - x1)
y - (-5) = -3(x - 3)
y + 5 = -3x + 9
y = -3x + 9 - 5
y = -3x + 4 = mx + c

A group of geologists is about to start excavating a new area for fossils. The area they are working in is the side of a cliff. Describe two pieces of information they will most likely be able to discover about the fossils they will find.
Answer:
Forms of fossils and there arrangement with layer of rock.
Explanation:
The seashore is a significant place for the depositional work of waves and it's also one of the significant places for the erosion and weathering of rocks. The presence of sedimentary rocks along the cliffs are essential for the discovery of fossils of plants and animals. Fossils of shells and other creatures that were of marine origin are mostly discovered near excavation sites. Fossil helps to prove the age of rocks and strata.First, you introduce to the parents the importance of karyotype test, by describing its ability to detect two broad categories of abnormalities in chromosomes, (1)______________________ and (2)_______________________.

In a test cross, a pure-breeding plant is crossed with a plant suspected to be heterozygous (Aa). What is the genotype of the pure-breeding plant?
Answer:
aa
Explanation:
In genetics, a test cross is a cross performed to determine the unknown genotype of a phenotypically dominant organism. The test cross is done by crossing the unknown genotype with a homzygous recessive organism. The result of this cross tell us whether the unknown genotype is heterozygous or homzygous dominant.
According to this question, a test cross was conducted involving a pure breeding plant with a plant suspected to be heterozygous (Aa). Based on the explanation of a test cross above, the genotype of the pure-breeding plant will be "aa". Note; it must be recessive.

In pulsus paradoxus, even if the pulse cannot be palpated, it can still be heard by using a BP cuff and stethoscope.
a. True
b. False
Answer:
False.
Explanation:
Pulse can't be heard by using a BP cuff and stethoscope because these devices are used to measure the heartbeat and blood pressure of the body. Digital monitors display both blood pressure and heart rate, but you can determine the pulse by checking your pulse by using hand while on the other hand, heartbeats can easily be heard using a good stethoscope so we can say that pulse can't be heard through BP cuff and stethoscope.
which fundamental units are involved in force do step Wise
Force = ma
We know, the unit that the S.I. unit of mass is Kg.
We also know that a = (v - u)/t.
We know that v = d/t and u = d/t and the S.I. unit of t(time) is s.
We know that the S.I. unit of d(displacement) is m.
So, the S.I. unit of v is m/s and the S.I. unit of u is m/s and the S.I. unit of t is s.
So, the S.I. unit of a is m/s×s or m/s²
So, the unit of force is
(unit of m) × (unit of a)
= kg × (m/s²)
= kg.m/s²
=
[tex]kg \: m \: {s}^{ - 2} [/tex]
Or more simply,
F = ma
=> F = m{(v-u)/t}
Putting units,
Newton = kg[{(m/s) - (m/s)}/s]
=> Newton = kg{(m/s)/s}
=> Newton = kg(m/s²)
=> Newton = kg.m/s²
=> Newton = kg.m.(s^-2)

Answer this question properly
Warfarin acts by inhibiting the activity of the VKORC1 protein, which helps to produce functional clotting factors. There is a variant in the VKORC1 gene that lowers the dose of warfarin required for treatment, and individuals with this variant have increased risk of bleeding when they are treated with warfarin. This variant is found 1639 base pairs upstream of the translational start site. This variant likely:______.
a. decreases the activity of the VKORC1 protein.b. increases the activity of the VKORC1 protein.c. decreases expression of the VKORC1 gene.d. increases expression of the VKORC1 gene.
Answer:
The correct answer - c. decreases expression of the VKORC1 gene.
Explanation:
Mutation of Guanine nucleotide into Adenosine is the reason for this particular type of mutation. This mutation expresses the less expression of the VKORC1 protein.
The mutation results in a decrease in the affinity of the binding site of the transcription factor which causes less expression. Since the VKORC1 protein is less in the body so Warfarin doses are decreased
Thus, the correct answer is - decreases expression of the VKORC1 gene.
