Answer:
By comparing a fossil to similar rocks and fossils of known ages, relative dating can be used to estimate its age. Absolute dating is a method of determining the precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil itself or, more commonly, the rocks that surround it.

Kudzu, a plant native to eastern Asia was introduced into America in 1876. In 1935, Kudzu was planted along southern roadways to control soil erosion. Adding a foot of vine a day in the spring and summer
kudzu quidity grew out of control. Why can introducing a new species to an existing ecosystem often be a disaster?
A The new species can create excess nutrients in the soil that can damage native species
The series can harminative anime and damage the ecosystem
Answer:
Due to lack of biological gent.
Explanation:
Introducing a new species to a new ecosystem often leads to a disaster because of the absence of bioagent for that species. Bioagent are those organisms which has the ability to control other organisms by feeding on them. A new species does not make problem in its old or original ecosystem due to the presence of controlling agents but in the new ecosystem there is no bioagent that can stop its growth so that's why sometimes the introduction of new species leads to a disaster.

Challenge question! Imagine the following situation. You receive a viral vector coronavirus vaccine that uses a specific adenovirus and your immune system mounts a strong immune response. At the same time, your friend receives an RNA coronavirus vaccine and also has a strong immune response. One year later a new coronavirus variant emerges and neither of the original vaccines protect people from this new variant.
A new viral vector vaccine is developed to the variant using the same adenovirus as before. In clinical trials, it is found that the new vaccine protects people that originally received the RNA coronavirus vaccine that your friend had but does not protect people that originally received the viral vector coronavirus vaccine that you had.
Question: Can you think of an explanation for why the new vaccine didn’t protect you, but did protect your friend?
Answer:
she took more care of her self and her immune system its more advance rather than the other person!
Explanation:
Due to being more careful meaningly taking care of not catching it, but also just cause you had it doesnt mean you're going to be carless "free" because you got the vaccine.
your friend could've been protected even though she had the vaccine she was not carless unlike the other person she thought about her actions.

Which of the following best explains how the prokaryotic expression of a metabolic protein can be regulated when the protein is already
present at a high concentration?
Answer:
A. Repressor proteins can be activated and bind to regulatory sequences to block transcription.
Explanation:
its A
The best explanation for the prokaryotic expression of a metabolic protein is repressor proteins can be activated and bind to regulatory sequences to block transcription.
What are metabolic proteins?Protein helps with growth and repair. Proteins have the potential to serve as a metabolic fuel source in addition to all of these important functions.
Excess proteins must be converted into glucose or triglycerides and used to provide energy or build energy reserves because proteins cannot be stored.
Thus, the correct option is A.

DNA sequencing is the method which can be used in order to identify the bacterium that was isolated from the contaminated river. DNA sequencing is the process in which the sequence of nucleotides is determined that is present within a DNA molecule. For identifying the bacterium, the sample of bacteria is collected. After sample collection is completed, genomic DNA is extracted from the bacteria and DNA sequencing will be done of that bacteria.
Justin wants to know how much gas his mother will save if he rides his bike to school rather than being driven in the car. For one month, Justin rides his bike to school. Every week, he asked his mother how much gas she put in the car. The next month, Justin had his mother drive him to school. Again, every week he asked her how much gas she put in the car. What could Justin do to improve this experiment?
Answer:
ask his mother?

Answer:
it says that plants are the main source of nutrients and energetic materials and when the cow feed on them, it consumes some of the benefits that we miss when we eat beef
Answer:
Question 6: The answer is the energy, because it collects more energy than the cow. When the cow eats plants, the energy from the plant decreases leaving the cow with only little amount.
Question 7: I agree, Because plants holds way more nutrients and energy than meat. I could support that by saying when a herbivore eats from a plant, It only recieves 10%.

A lever used to lift a heavy box has an input arm of 4 meters and an output arm of 0.8 meters. What is the MA of the lever?
Answer:
Mechanical advantage = 5
Explanation:
Given the following data;
Length of input arm = 4 meters.
Length of output arm = 0.8 meters.
To find the mechanical advantage;
[tex] Mechanical \; advantage = \frac {Length \; of \; 1nput \; arm}{Length \; of \; 0utput \; arm} [/tex]
Substituting into the formula, we have;
[tex] Mechanical \; advantage = \frac {4}{0.8} [/tex]
Mechanical advantage = 5
