a population of white moths lives in a forest near a factory. this factory burns coal and pollutes the air with black dust. over time, this dust has settled on the trees in the area, making them darker in color. this could result in
1. an increase in the white moth population.
2. a decrease in the white moth population
3. an increase in the number of trees in the area
4. a decrease in the air pollution affecting the area

Answers

Answer 1
The answer to your question is option b

This is because if the trees are black, and covered with soot due to the pollution, caused by industrialisation, the white moths will be easily seen and constantly hunted by the predator, compared with the black moth population as they camouflage easily. Ultimately, the white moths would be hunted to such an extent that their population would dramatically decrease

Answer: what is obtain from a warm water that affects typhoons? = The link isn’t terribly surprising, given that warm waters are the fuel for the convection at the heart of tropical cyclones. Storms tend to leave a cool “wake” behind them, as they churn cooler waters from below. But if that water is relatively warm, it makes sense that the typhoons would see a bigger boost.

2. How do bodies of water affect typhoons? = They affect typhoon based on what or how strong the energy is released by the landforms and bodies of water. Typhoons gain energy from warm ocean water and lose energy over cold water.

some cases of cjd may be caused by a mutation of the prp gene.
T/F

Answers

True. Some cases of Creutzfeldt-Jakob disease (CJD) may be caused by a mutation of the prion protein (PRP) gene.

The PRP gene is responsible for the production of a protein found in the brain and nervous system, which can become misfolded and lead to the development of prion diseases such as CJD. While the majority of CJD cases occur spontaneously or due to exposure to contaminated tissues, a small percentage of cases are linked to inherited genetic mutations of the PRP gene. These genetic mutations can cause abnormal folding of the PRP protein, leading to the accumulation of prions and the onset of CJD. Testing for PRP gene mutations can be helpful in diagnosing and understanding the underlying causes of CJD in affected individuals and their families. However, it is important to note that PRP gene mutations are rare and not all cases of CJD are caused by genetic factors.

What is protein synthesis?

Protein synthesis is the process by which new proteins are produced in the cell. Their destiny vary according to the protein and the cells needs.

Two processes are involved in protein synthesis,

Transcription occurs first in the nucleus. During this event, mRNA is synthesized by copying a segment of the DNA molecule. The template DNA strand is used to pair its nucleotides and grow the new mRNA strand.

Translation occurs in the cytoplasm. During this event, the protein is grown by reading the mRNA codon sequence. tRNA, associated with rRNA, recognizes the codons and adds the correct amino acid to the new growing polypeptide.

During protein growth, the molecule passes from the cytoplasm to the rough endoplasmic reticulum where protein growth finishes, and from there, the molecule is tasported in vesicles to the Golgy apparatus where it suffers its final modifications.

If a farmer was estimating yield for a grain crop, what variables would he or she need to make a calculation?

A. cost of herbicide per ft2, seeding rate, estimated storage space cost of herbicide per ft, 2, , seeding rate, estimated storage space

C. cost of seeds per ft2, acres of planted field, fertilizer weight cost of seeds per ft, 2, , acres of planted field, fertilizer weight

D. acres of planted field, kernels per ft2, standard kernel weight

Note: Here is the resource to finding the answer -> Estimating yields and calculating yield involve numerous equations, depending on the crop in question, and many different methods exist. For grain crops, a farmer could count the number of viable kernels in a square foot. This number would then be multiplied by a standard 1,000 kernel weight. Finally, this number should be multiplied by the number of acres on a farm. One of the most crucial measurements a farmer needs to consider is planting rate. Planting rate, also known as seeding rate, refers to the number of plants sown in a certain area, usually calculated in hectare or acres, to ensure a maximum yield. Intuitively, one would think that the more plants planted, the higher the yield. But as we see from the example of SRI at the beginning of this lesson, planting rates can be counterintuitive. Planting fewer plants can mean growing larger, healthier plants that result in more grains, beans, or seeds. Needless to say, a farmer’s crop yield is predicated on his or her initial planting rate. <-

Would you expect the molecular weight approximations to be closer to true values for larger or smaller proteins? Why?

Answers

You can expect molecular weight approximations to be closer to true values for larger proteins.

This is because larger proteins have a greater number of amino acids, which makes their molecular weight more significant. Any discrepancies or errors in measuring the molecular weight will have a smaller relative impact on larger proteins compared to smaller proteins. As a result, the approximation will be more accurate for larger proteins. You can expect molecular weight approximations to be closer to true values for larger proteins.

What are the latest developments on research on Earth’s internal structure.

Answers

Answer:

The internal structure of the earth is like a steel ball that has been inserted into the middle of a rubber ball that has then been rolled around in the mud which sticks to it.

Explanation:

The mud sticking unevenly on the outside of the ball represents the earth's crust. The rubber ball represents the mantle below the crust, and the steel ball inside is the earth's core. These are the basic layers.

Inside the earth, the mantle itself consists of an upper mantle and a lower mantel, and the iron consists of an outer core and inner core. The separations occur where the state of the substance changes. For the iron , the outer core is closer to a liquid, while the inner core is closer to a solid. Both are intensely hot.

If you need a 3-D representation of the internal structure of the earth, cut a spherically shaped avocado in half, and keep the half with the seed or pit. The pit is the core, the fruit is the mantel and the skin is the earth's crust. You can add in the other divisions as necessary.

Why is it advantageous for humans to have two eyes as opposed to just one?

We develop stereoscopic vision, or the capacity to recognize and comprehend three-dimensional space from any visual inputs, with the assistance of two eyes. With both eyes open, you can see 180°, compared to 150° with just one eye. This gives us a greater field of view. Whereas, when we close one eye, we get the angle till our nose blocks the view. We, humans, are largely binocular beings.

The statement, "The reabsorption of water along the descending limb of the loop of Henle brings the osmolarity of the filtrate moving down the descending limb from isoosmotic to hyperosmotic. While reabsorption of Na+, K+, and Cl- along the ascending limb of the loop of Henle will bring the osmolarity from hyperosmotic to isoosmotic as the filtrate moves to ascending direction" is True.

The following statement about anti-diuretic hormone (ADH) is TRUE:

a. ADH promotes the production and insertion of aquaporin 2, 3, and 4 in the principal cells at the distal convoluted tubule and collecting duct.

ADH in the supraoptic and paraventricular nuclei of the hypothalamus and secreted from the posterior pituitary gland. Its main function is to control water balance in the body. The hormone encourages water reabsorption from the urine in the kidney tubules, causing a decreased amount of urine to be produced. Aquaporin-2 channels are inserted into the luminal membrane of the principal cells by ADH in the distal tubules and collecting ducts to enhance water reabsorption. Thus, alternative (a) is a TRUE statement about anti-diuretic hormone (ADH).

The following statement about glycolysis is TRUE:

b. The net production is 2 pyruvate + 2 NADH + 2 ATP.

Glycolysis is the catabolic process of glucose into pyruvate, producing energy through substrate-level phosphorylation. The process is anaerobic and takes place in the cytosol. The process requires two ATP to start and yields four ATP and two NADH as a net result. Glucose is converted into 2 pyruvate by hexokinase or glucokinase. Therefore, the statement b is a TRUE statement about glycolysis.

July was a tough month for food producer Tiger Brands, which suffered a R100 million in stock loss due to unrest in parts of Gauteng and KwaZulu-Natal, coupled with an additional R647 million loss following a major recall of some of its canned products. The unrest started following the arrest of former president Jacob Zuma for disregarding the Constitutional Court by refusing to appear before the State Capture Inquiry, but morphed into waves of violence and looting, potentially wiping R50 billion off South Africa's GDP. Tiger Brands' properties were looted and destroyed in the violence. This incident was shortly followed by the recall of 20 million KOO and Hugos canned vegetable products due to potential defects in the cans. In a trading update on Tuesday, the company, whose brands also include Jungle Oats, Oros and Purity said it lost hundreds of millions because of both events.
