How is Cytochrome C, which is an important enzyme in cellular respiration, used to provide evidence for evolution
Answer:
Cytochrome c is known to play a role in the electron transport chain and cell apoptosis. However, a recent study has shown that it can also act as an antioxidative enzyme in the mitochondria; and it does so by removing superoxide (O2–) and hydrogen peroxide (H2O2) from mitochondria.Therefore, not only is cytochrome c required in the mitochondria for cell respiration, but it is also needed in the mitochondria to limit the production of O2– and H2O2.

Answer:
Genotypic- 1:1
Phenotypic- 1:1
Explanation:
For this problem, I will use the letter A to represent the alleles. The first parent's genotype would be Aa, and the second parent would be aa. Then, using a punnet square to cross the two parents the outcome is Aa, Aa, aa, aa. This means there is a 50% of a mixed individual and a 50% of a purebred recessive. Both phenotypes also have a 50% chance of being expressed. Since the percentages are equal both ratios are 1:1.
A man with homzy type A blood and a woman with heterozygous type B blood want to know the probability of having a child with type AB blood.
Answer:
[tex]\frac{1}{2}[/tex]
Explanation:
Homzy. type A blood = AA
Heterozygous type B blood = Bb
Punnett square
| B | b
A | AB | Ab
A | AB | Ab
The ratio is = 2:2 = 1 : 1
The total number of outcomes are 4
The number of AB are 2
Thus the probability is [tex]\frac{2}{4} = \frac{1}{2}[/tex]
Is groundwater always cleaner than surface water?
(つ ^-^ )つ Hey There!
Answer : Groundwater is generally much cleaner than surface water. So ✨Yes✨
Why : Groundwater is less susceptible to pollution than surface water because as water enters the ground, the soil and rocks naturally filter much of the water as it passes through the ground.

When the Linnaean system of classification was first developed in the early 1700s, it only had two kingdoms for living things, the plant and animal kingdoms. Three more kingdoms have been added since then, as well as a higher division of three domains. Why are we still using this system if we have to keep changing the way it is organized? (4 points)
Group of answer choices
The general system still works despite all the changes each generation of scientists has added.
Each change represents new species that have evolved since the system was developed.
The changes reflect increases in our knowledge of the structure and operation of living things.
It has been used for so long that it would be difficult to change to a different one.

Which change is an example of a response to a stimulus?
1.
The pupil of an eye decreases in size in bright light.
2.
A leaf absorbs sunlight in the morning.
3.
The water level of a pond rises on a rainy day.
4.
A dead tree decays after many years.
S
Answer:
1
Explanation:
The example of the response to stimulus is the contraction of the pupil of eye in response to the bright light. Thus, option A is correct.
The stimuli are the things or events that causes the detectable change in the organism. The reaction of the organism with response to the stimuli is measured in terms of sensitivity.
What is a stimulus response?The stimulus response is created when the external event or the thing brings changes in the chemical or physical nature. The response to stimuli are instant reactions.
The decrease in the pupil size with the light as the stimulus is the response of eyes.
Thus, the example of the response to stimulus is the contraction of the pupil of eye in response to the bright light. Thus, option A is correct.

Energy from the sun arrives as electromagnetic radiation with a wide range of wavelengths and frequencies. Which form of electromagnetic radiation has more energy than visible light waves have?
A.radio wavesB.infrared wavesC.microwavesD.ultraviolet waves
D. Ultraviolet waves
Ultraviolet radiation carries more energy and infrared radiation, radio waves and microwaves carries less energy than visible light. All radiation from the sun with a wavelength below 290 nm, that is most high-energy UV-radiation, is filtered out by the atmosphere before reaching the Earth's surface.Ultraviolet radiation has shorter waves than blue or violet light, and thus oscillates more rapidly and carries more energy per photon than visible light does.The visible wavelengths cover a range from approximately 0.4 to 0.7 µm.Thus, correct option is option D.

Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. ... Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R)
Explanation:
Heat is the form of energy that gives the sensation of warmth to us.
Whereas
Temperature is the degree of hotness or coldness of a body.
The SI unit of heat is joule.

Choose all correct answers.
soil erosion

poisoned wildlife from pesticides
Answer:
it is soil erosion, habitat loss and poisoned wildlife from pesticides.
Explanation:I took the test just now and I got the question right.
The environmental effects of farming include soil erosion, habitat loss, and poisoned wildlife from pesticides.
What are environmental effects of farming?Farming can have significant environmental effects, both positive and negative. On the positive side, farming can help to sustain and enhance biodiversity by providing habitat for wildlife and conserving genetic diversity in crops and livestock. Farming can also help to mitigate climate change by sequestering carbon in soils and reducing greenhouse gas emissions from energy use and land use change.
However, farming can also have negative environmental effects, such as soil erosion, water pollution, habitat loss, and pesticide contamination. Other negative effects include the depletion of soil nutrients, the loss of topsoil, and the emission of greenhouse gases from livestock and fertilizer use. Addressing these negative effects requires a holistic approach that considers the interconnections between agriculture, ecosystems, and human wellbeing.
