name two components of blood that are not present in glomerular filtrate
Answer:
Filterable blood components include water, nitrogenous waste, and nutrients that will be transferred into the glomerulus to form the glomerular filtrate. Non-filterable blood components include blood cells, albumins, and platelets, that will leave the glomerulus through the efferent arteriole.
:_:
Blood cells and plasma proteins are the two components that are not present in glomerular filtrate.
What is blood cells?"A blood cell is a cell produced through hematopoiesis and found mainly in the blood."It includes RBCs, WBCs and platelets.What are plasma proteins?"Plasma proteins are proteins present in blood plasma."It plays an important role in immune system.What is glomerular filtrate?The filtrate formed after filtration of blood in the glomerulus is called glomerular filtrate. It consists majorly of water and other constituents such as amino acids, glucose, potassium, sodium, urea, uric acid and ketone bodies.The filtrate does not contain RBCs, WBCs, platelets and plasma proteins.

Explain the reason the Type AB and Type O blood phenotypes always have the same
genotype, whereas the Type A and Type B blood phenotypes have two possible allelic
combinations.
Answer:
Because A is co-dominant to B and O is recessive, so the genotype is the same as the phenotype. But A can have 2 genotypes because A can mask a recessive allele, which makes the phenotype A. B can also mask a recessive allele, which makes the phenotype B.
Examples
AO (genotype) = A (phenotype)
BO (genotype) = B (phenotype)

Explain the role of insulin in the homeostatic regulation of blood glucose levels
Answer:
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

Agriculture is the leading source of pollution in many countries. Pesticides, fertilizers, and other toxic farm chemicals can poison fresh water, marine ecosystems, air, and soil. They also can remain in the environment for generations.
What are the major environmental problems caused by agriculture?Agriculture contributes to a number larger of environmental problems that cause environmental degradation including climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Fossil fuels began to be used, which led to increased pollution, and the construction of factories led to the loss of habitat for many wild animals. The development of agriculture has led to the emergence of new plant varieties, domestication of animals, and disturbance of soil composition.
Therefore, some of the environmental problems caused by the agriculture and natural resource industry are well described above.

not true?
A always pairs with T.
C always pairs with G.
Talways pairs with G.
Answer:
T always pairs with G
Explanation:
According to the complementary base pairing rule as postulated by Chargaff, an Adenine base (A) will always hydrogen pair with a Thymine base while Cytosine base (C) will always hydrogen pair with Guanine base (G) in a DNA molecule.
That is; A - T and G - C
Hence, based on the question, the pairing of Guanine and Thymine is incorrect.

What is the sequence of amino acids formed from this gene?
Listen to pronunciation. (uh-MEE-noh A-sid SEE-kwents) The arrangement of amino acids in a protein. Proteins can be made from 20 different kinds of amino acids, and the structure and function of each protein are determined by the kinds of amino acids used to make it and how they are arranged.
What is the answer of the question?
Answer:
A. Amino Acid, protein, gene.
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A gene can be defined as a complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Simply stated, a sequence of biomolecules which are responsible for coded genetic instructions in all living organisms is known as nucleotides.
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
Furthermore, the two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Additionally, the proteins which are mainly synthesized based on the genetic instruction codes in deoxyribonucleic acid (DNA) determines the trait of living organisms.
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Hence, when you remove a nucleotide from a gene, the order of nucleotides shifts and as such resulting in new amino acid being coded for. These new amino acid will combine to form a different protein than what the gene was originally coded for.
