Answer:
Negative feedback.
Explanation:
The production of erythropoietin by the liver and kidneys is a negative feedback because with the production of erythropoietin, our body tends to move to become more stable state. The erythropoietin is produced by the liver and kidneys to increase the production of red blood cells if the quantity of red blood cells are lower than the normal range. If the number of red blood cells are decreases the oxygen level in our body is low that leads to unstable condition of the body but when the concentration of red blood cells increases, the body move towards stability.

How would adding finer particles to the sand affect porosity?
Explanation:
Porosity depends on the size, shape, and mixture of grains and particles that compose soil and rock. For instance, small particles such as clays can compact more closely together, reducing the amount of porosity. However, larger particles such as sand and gravel will have more spaces available between them.

Water flow improves in the aftermath of a forest fire because
rain always puts out fires.
no living organisms survive fires, decreasing demand.
they clear the land, allowing more water to flow over it.
much of the water in a local watershed will be used to fight the fire.
A major impact of combustion on water quality is the potential for increased precipitation. Runoff can carry suspended soil particles, dissolved inorganic nutrients, and other materials into nearby rivers and lakes, degrading water quality and damaging fish habitat.
Park Williams, an associate professor of geography at UCLA and lead author of the study, said wildfires burn vegetation that would otherwise draw water from the ground and block precipitation before it reaches the ground. said to improve the flow.
Wildfires increase the vulnerability of watersheds to flooding and erosion, causing short-term and long-term damage to water supplies. may have an impact. The increased cost of treatment, the need for alternative medicine, and reduced storage capacity. Fire as a destructive force can rapidly consume large amounts of biomass and cause adverse effects such as soil erosion, post-fire water runoff, and air pollution.

Which of these is the correct complementary DNA strand for the segments shown?
A)5’ AGGYCAGGT 3’
B)5’ ACCUGAGGU 3’
C)5’ TGGACTGGA 3’
D)5’ TCCACTCCA 3’
Answer:
5’ TCCAGTCCA 3’
Explanation:
The correct complementary DNA strand for segment 3’ AGGTCAGGT 5’ is 5’ TCCACTCCA 3’. Thus, the correct option for this question is D.
What is a Complementary DNA strand?A complementary DNA strand may be defined as a type of DNA strand in which the series of the constituent molecules on one strand of the double-stranded structure is chemically similar to the sequence on the other strand.
According to Chargaff's rule, the complementary DNA strand is formed with the concept of base pairing, where Adenine is complementary to Thymine and cytosine is complementary to Guanine.
Due to this, A=T, G=C, G=C, T=A, C=G, A=T, G=C, G=C, and T=A. This matches option four given in the question.
Therefore, the correct complementary DNA strand for segment 3’ AGGTCAGGT 5’ is 5’ TCCACTCCA 3’. Thus, the correct option for this question is D.

Which organism obtains energy without directly depending on another organism
The organism that obtains energy without directly depending on another organism is a PLANT.
PLANTS are organisms which are capable of manufacturing their own food through the process of photosynthesis.
Photosynthesis is defined as the process by which plants use low energy containing inorganic compounds (example carbondioxide and water) in the presence of sunlight, as energy, to produce high energy organic compounds such as sugar. These sugar are used as source of energy in the plant cells.
While animals are the organisms that directly depend on plants( another organism)
Therefore, the organism that obtains energy without directly depending on another organism is a PLANT.

Block the promoter region of a gene. [ Choose ]
Found associated with the gene encoding HCl production in a skin cell. [ Choose ]
Found associated with the genes encoding hemoglobin in a red blood cell [ Choose ]
Answer:
Increase transcription of a gene - Activator
DNA binding protein - Ribosome
Block the promoter region of a gene - Repressor
Found associated with the gene encoding HCI production in a skin cell - mRNA
Found associated with the genes encoding hemoglobin in a red blood cell - mRNA
Explanation:
Hemoglobin is an iron containing compound present in red blood cells which carries oxygen in the body. mRNA molecule contains exon coding for two proteins. mRNA molecule becomes associated with four to six ribosomes.
The statements on the left are correctly matched with the choices given on the right are:
Increase the transcription of a gene -------- Activator.DNA binding protein ------ Ribosome, Polymerases.Block the promoter region of a gene ------ Repressor. Found associated with the gene encoding HCl production in a skin cell -------- mRNAs.Found associated with the genes encoding hemoglobin in a red blood cell -------- mRNAs.What do you mean by a Gene?
A gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein.
An activator is known to increase the transcription of a gene, while a repressor binds to the promoter region and inhibits the transcription process. The molecules of mRNA get associated with the gene HBA, HBB which encodes for hemoglobin in red blood cells. Ribosomes and polymerases are known for DNA binding protein.
Therefore, above are all the statements on the left that are correctly matched with the choices given on the right.
