As part of a resource recovery project, a city decides to open reuse centers.
What kind of materials might a reuse center accept?
A. Household garbage
B. Industrial waste
C. Leftover art supplies
D. Yard trimmings
The reuse center might accept: D. Yard trimmings
What is a reuse center?
A reuse center, also known as a recycling center or a second-hand store, is a facility where various materials and items that are still in usable condition are collected, sorted, and made available for resale or redistribution. The main goal of a reuse center is to divert materials from the waste stream and promote their reuse, extending their lifespan and reducing the demand for new products.
These centers typically accept a wide range of items, such as furniture, appliances, clothing, electronics, books, toys, and more. By accepting and selling these items at affordable prices, reuse centers help reduce waste, conserve resources, and provide affordable options for individuals and communities.
A reuse center can accept yard trimmings as it include grass clippings, leaves, branches, and other organic waste from landscaping and gardening activities.

A genetically heterogeneous population of rice has a mean in the number of days to maturation of 30. Selection for decreased period of maturation is carried out for one generation. The average period to maturation among the plants selected as parents for the next generation is 25 days. F1 plants mature on average in 27 days. Estimate the narrow sense heritability.
Answer:
h² = 0.6
Explanation:
Before answering the question, we need to know a few concepts.
Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations.
Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced.
The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,
SD = X₀ - Xs
Heritability in the strict sense, h², is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.
h² = R/SD
The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.
R = h²SD
R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),
R = X₀ - X₁
-------------------------------------------------------------------------------------------------------------
Now that we know these concepts and how to calculate them, we can solve the proposed problem.
Available data:
You are selecting rice´s decreased period of maturation. The population of rice has a mean maturation time of 30 days → X₀ Parental selected average period to maturation is 25 days → Xs F1 plants mature on average in 27 days → X₁ N arrow sense Heritability → h²According to what we sow previously, we need to find out the value of h².
We know that h² = R/SD, so we need to get R and SD first.
R = X₁ - X₀
R = 27 - 30
R = -3
SD = Xs - X₀
SD = 25 - 30
SD = -5
Knowing this, we can calculate h²
h² = R/SD
h² = -3/-5
h² = 0.6

Many anti-evolutionists believe that since science doesn't have answers for all questions; scientific conclusions are not necessarily correct. This attitude reflects a failure to understand the nature of science. What is the general nature of scientific thinking? In what way is science "self correcting"?
Answer:
In science, accepted theories do not represent absolute truths. A scientific theory is accepted when there is much evidence available that support its statements, but new lines of evidence can modify original presumptions
Explanation:
A scientific theory is a plausible explanation of a particular phenomenon of the natural world, which has been many times tested and verified by using the scientific method. The accepted theories are progressively modified (or even overturned) as new lines of evidence emerge. In consequence, a scientific theory is composed of statements that we consider as truths regarding the available evidence, but we have no absolute certainty that such statements are true. The ability to self-correct is fundamental in science and it happens when we discover that the original statements of a scientific theory were wrong, thereby new lines of evidence allow us to correct the error and/or develop new scientific theories.

D. The temperature of each container
Answer:
well, what I got was wrong.
Explanation:
for me A. the kind of containers used was wrong along with c. the number of crickets together. a and c was incorrect for me. so it would probably maybe be b. the temperature of each container with d. the number of crickets in each container?

Suppose that you close a window because you notice that rain is falling. Your action in closing the window is a(n)
A. involuntary reaction.
B. depressant.
C. stimulus.
D. response.
Answer:
D. Response
Explanation:
Basically, You Are Coordinating What Is Happening Which Triggers The Brain For A Response.
Answer:
D.
Explanation:
You are responding to the rain by closing the window.
- it is not an involuntary action because that is something that doesn't require thinking such as breathing and blinking.
- it is not a depressant because that is something that reduces functional activity - so affects the body.
- it is not a stimulus because a stimulus is a change or signal in the environment that can make an organism react. So, in this case the rain would be the stimulus.

Explanation:
Gene X always produces the same mRNA (one splice form) and the same protein in all cells in which it is expressed. The same amounts of gene X mRNA and protein are present in brain, kidney, and heart cells. However, the activity associated with the protein is present only in the heart. Which of the following are possible explanations?
a. A splicing factor necessary for removing all of the primary transcript's introns is present only in the heart.
b. A splicing factor necessary for removing all of the primary transcript's introns is present only in the brain and kidney.
c. Protein X is phosphorylated only in the heart.
d. Protein X is phosphorylated only in the brain and kidney.
There are two explanations for this phenomenon: phosphorylation of the protein X in the heart activates its function (Option C) or phosphorylation of the protein X in the kidney and the brain deactivates its function (Option D). Therefore, both Option C and Option D are correct.
Phosphorylation is a posttranslational protein modification that is capable of activating or deactivating protein function.
Phosphorylation alters the three-dimensional structure of a protein, thereby modifying its function (i.e., activate or deactivate the target protein).
Phosphorylation occurs at specific amino acids (e.g., serine and threonine residues) of the target protein.
Moreover, mRNA splicing (RNA processing) occurs before the protein state, it is a transcriptional process. This process consists in removing the non-coding regions or 'introns' from pre-mRNA and subsequent joining protein-coding regions or 'exons' to enable the translation of the mRNA into a protein.
In consequence, in this case, it is possible that 1-phosphorylation of the protein X in the heart activates its function, or 2-phosphorylation of the protein X in the kidney and the brain deactivates its function. Therefore, both Option C and Option D are correct.

Match the following description with the appropriate type of respiration:
a. occurs in the mitochondria
b. resting muscles depend on this type of respiration
c. lactic acid builds up in muscle fibers
d. rapidly produces ATP for short time periods
e. produces large quantities of ATP but takes longer to synthesize
1. anaerobic respiration
2. aerobic respiration
Answer:
The correct answer is -
1. c, and d.
2. a, b, and e.
Explanation:
Anaerobic respiration is the short and quick way of producing energy, however, it produces less amount of energy than aerobic respiration and produces lactic acid as a byproduct. It takes place in the cytoplasm of the cell and working or acting muscles depend on such respiration.
Aerobic respiration is the main and important respiration process that takes place in mitochondria and it takes time to produce ATPs that are much more than anaerobic respiration. Resting muscles get energy by this type of respiration.

C. The rate of diffusion would be faster for the right cylinder.
D. The rate of diffusion would be faster for the sphere.
Answer:
the rate if diffusion will be faster in the right cylinder
