Answer:
This question lacks options, options are:A) Oxygen would no longer be reduced to water. B) No ATP would be made during transport of electrons down the respiratory chain. C) Mitochondria would show a burst of increased ATP synthesis. D) Glycolysis would stop. E) Mitochondria would switch from glycolysis to fermentation.The correct answer is B)
Explanation:
The main mechanism of ATP production takes place in our mitochondria, which are cellular organelles, and this occurs when molecules of coenzymes or reduced prosthetic groups, coming from the process of catabolism of nutrients, are oxidized with molecular oxygen (which becomes in water), leading to the production of ATP. DNP works by increasing heat production in cells through a process known as decoupling. Dinitrophenol is an ionphoric compound that cuts mitochondrial ATP production circuits. This cessation of ATP production through the mitochondria leads to an increase in metabolic rate (as the substrate is used at a higher rate so that cytosolic ATP can sustain life) and subsequent weight loss.

The sensor or detector tells the integrating center what needs to be done
True
False
Answer:
True
Explanation:
It is true because a sensor or detector is an organ that detects external stimuli from the environment or changes in both internal and external environment, it then send the information to the integrating center.
The integrating center receive stimulus or information from sensor and activate responses to the stimulus.

Please answer this is super easy 6th grade science! Thanks!
Answer:
The answer should be A. lithosphere.
Explanation:
Firstly, let's look at the options:
C. and D, both parts of the Earth at the core, have almost nothing to do with the Earth's crust or tectonic plates except maybe having a passive effect on them.
B. mantle is where the lava that moves the tectonic plates circulates due to convection, which is the reason they move at all. But, it is not where the tectonic plates themselves are.
Therefore, finally, we have A as the answer.
(As a sidenote, the "lithosphere" means the Earth's crust.)

Which scientific discipline is correctly matched to a contribution to society?
The options are;
A) biology; theory of relativity
B) geology; theory of continental drift
C) ecology; discovering new elements
D) astronomy; developing quantum mechanics
Answer:
B) geology; theory of continental drift
Explanation:
Looking at the options;
-theory of relativity is a topic in physics originated by Einstein. Thus, it is matched to physics and not biology.
- theory of continental drifts are related to plate tectonics where it explains how continents shift position on Earth's surface. This is a branch of Geography and is thus correctly matched.
- discovering new elements is a topic under chemistry and not ecology. Thus, this is not matched correctly.
-developing quantum mechanics is a topic in physics that deals with the relationship between energy and matterwith respect to atomic and subatomic scale. Thus, it is not well matched.
Therefore correct answer is option B
3. On a particular planet, it takes 850 J for a 50 kg remote probe to launch
itself up 2 m. What is the gravitational field strength on the planet?
Answer:
the gravitational field strength is 8.5 N/kg .
Explanation:
PE = mgh
where,
PE is Potential Energy
m is the mass
g (a) is the acceleration
h is the height
Substitute the value we get
→ 850 = 50×a × 2
→ 850 = 100×a
→ a = 850/100
→ a = 8.5m/s²
Acceleration is 8.5m/s².
Now, Calculating the Gravitational Field Strength

How can traits affect fitness and how
can natural selection change the
presence of certain alleles over time?
Answer: Natural selection allows the survival of organisms with beneficial traits.
Explanation:
Natural selection can be defined as the differential survival and reproduction of the members of the population that have beneficial phenotypic traits to survive in unfavorable environment. These organisms reproduce and pass on their traits to the next generation such species does not extinct in future.
The natural selection allows evolution of species with the adaptation of new traits so as to allow the survival of the organism.

55) Cells require which of the following to form cilia or flagella?
A) centrosomes
B) ribosomes
C) actin
D) A and B only
E) A, B, and C
Answer: D) A and B only
Explanation:
Centrosomes and Ribosomes are both present in the animal cell with both of them having different roles. Centrosomes have roles in cell divisions as they maintain chromosome number during the process and Ribosomes are in charge of the synthetization of proteins.
These two share a role together which is that they are both needed by the cell in order to form either cilia or flagella.
What is the purpose of having leak and gated channels for the neuron?
Answer:
Explanation:
The purpose of having leak and gated channels for the neuron is that the leak channels will allow the movement of sodium and potassium across the cell membrane downward from high concentration gradient to low concentration gradient. With the leakage of ions across the cell membrane, there is maintainence of a stable resting potential of cells.

C. gg- yellow color
Heterozygous means the individual has one copy of the recessive gene and one for the dominant gene. That means the genotype will contain one capital letter and one lowercase letter. In this case, which is complete dominance the dominant gene will manifest in the heterozygous form.
The correct answer is A. Gg-Green color
S. cerevisiae occurs in nature on ripe fruit. S. epidermidis naturally occurs on human skin. How do experimental results relate to the natural environment of each microbe?
Answer:
S. cerevisiae needs natural environment present on ripe fruit while S. epidermidis needs natural environment present on human skin.
Explanation:
S. cerevisiae occurs in nature on ripe fruit because the environment is suitable for them that provides food in the form of sugar while S. epidermidis naturally occurs on human skin because it needs wet and humid environment which is available on human body such as armpits. Due to the presence of suitable environmental condition, both S. cerevisiae and S. epidermidis are present on fruits and human skin respectively.

What are the charges both inside and outside of the neuron before you click the stimulate neuron button?
Answer:
The correct approach is "Negative and Positive".
Explanation:
Just outside of the neurons, the electrostatic interactions seem to be extremely favorable or positive (+) as well as the ion mostly with the greatest proportion was indeed sodium. Throughout intracellular space, a large amount of protein would be negatively charged, or even just potassium channels predominate. Under those same circumstances, the ion channels also seem to be inaccessible.For this specific purpose, this same lying down the neuron, before obtaining a stimulus, introduces positively charged on the external social but instead negative (-) inside though.

If the frequency of the disorder in the population is 0.0070, what is the percentage of heterozygous carriers
Answer:
15.322 %
Explanation:
Supposing that this is a recessive disorder and the population is in Hardy-Weinberg equilibrium:
p² + 2pq + q² = 1, where
1- the genotypic frequency of the homo-zygous dominant allele is p²,
2- the genotypic frequency homo-zygous recessive allele is q², and
3- the genotypic frequency heterozygous allele is 2pq
Therefore:
q² = 0.007 >> q = √ 0.007 = 0,0836
p = 1 - q = 1 - 0,0836 = 0.9164
2pq = 2 x 0.9164 x 0,0836 = 0.15322 (or 15.322 %)
What happens after the gated channels close?
Answer:
Explanation:
After the gated channels close, which is as a result of depolarization of voltage, the positive charge that has been increased in the cell will make the potassium channels to open and this will gush out of the cell through its electrochemical gradients. When potassium ion move out of the cell, the membrane potential begin to get to resting potential.
