5) which body system does each of the 3 germ layers give rise to?
Answer:
Germ layers - Groups of cells that form 3 distinct regions of the embryo & give rise to specialized cells and organs.
Ectoderm - Epidermis and nervous system
Mesoderm - Heart, kidney, gonads, bones and muscle.
Endoderm - Lungs and digestive system.
Explanation:
Cells in each germ layer differentiate into tissues and embryonic organs. The ectoderm gives rise to the nervous system and the epidermis, among other tissues. The mesoderm gives rise to the muscle cells and connective tissue in the body. The endoderm gives rise to the gut and many internal organs.
Which is the active, growing state of endospore-forming bacteria?

Epithelial cells of kidney tubules may have many microvilli. what is the reason for the microvilli?
To expand the surface area of the tubule and maximize the reabsorption of vital chemicals, the cells lining the proximal convoluted tubule develop microvilli. Microvilli are hair-like protrusions that come from a cell's nucleus.
Reabsorption- Water and other solutes are reabsorbed as they return from the tubule to the plasma. Over the whole length of the renal tubule, various amounts of water and particular solutes are reabsorbed.
Proximal Convoluted Tubule (PCT)- Between Bowman's capsule and the loop of Henle, the proximal convoluted part of the vertebrate nephron plays a key role in the resorption of water, sodium, and chloride ions, and sugar from the glomerular filtrate.

Dna helicase inhibitors are well studied as potential drug targets. What would you expect to see if dna helicase activity is inhibited?.
DNA strands are separated and ATP hydrolysis is catalyzed by the helicase, preventing the unwinding of the double helix.
What is helicase?Nucleic acid or nucleic acid protein complexes can be altered or bound by enzymes referred to as helicases. Helicases are present in both DNA and RNA. DNA helicases are essential for DNA replication because they separate double-stranded DNA into single strands, enabling each strand to be copied. During DNA replication, DNA helicases unwind DNA at regions known as origins, where synthesis will start. The replication fork is a structure that develops as the DNA helicase unwinds the DNA. It is so called because the two strands of DNA appear to fork as they are unzipped apart. The hydrogen bonds that bind the nucleotide base pairs of the double-stranded DNA together must be broken using energy.Learn more about the helicase with the help of the given link:

What are the five regions of the vertebral column? describe one differentiating feature of the vertebrae in each region.
The five regions of the vertebral column are cervical, thoracic, lumbar, sacral, and coccygeal (or caudal) regions. One differentiating feature of these vertebrae includes their primary functions.
The vertebral column is the central axis of all vertebrates. It protects the spinal cord, provides attachment to the muscle cells, and supports the trunk. It usually consists of 33 vertebrae. The vertebral column in mammals is composed of five different groups of vertebrae:
Cervical region
The primary function is to support the weight of the head. They are numbered C1 to C7. C1 and C2 allow movement of the head.
Thoracic region
The primary function is to hold the rib cage in its place and protect the heart and lungs. They are numbered T1 to T12. They allow limited movement only.
Lumbar region
The primary function is to hold the weight of the body. They have numbered L1 to L5. They allow holding heaving weight.
Sacral region
The main function is to connect the spine to the hip bones (iliac). The five sacral bones are fused and form the pelvic girdle along with the iliac bones.
Coccygeal region
The four coccyx bones provide support to the attachment of ligaments and muscles of the pelvic region.

Serous membranes line certain cavities within the anterior body cavity. This statement is FALSE.
Serous membrane, also known as serosa in anatomy, is a silky tissue membrane made of mesothelium that lines the interior of bodily cavities and their contents. It secretes serous fluid to permit greased sliding motions between friction surface. Organs housed in body cavities that don't open up to the outside are covered by serous membranes that line the body cavities. The epithelium secretes a thin coating of serous fluid that coats serous membranes.
An indication of a serous membrane is the lining of the thorax. The pleura is the name for the serous membrane found in the thorax. The visceral pleura, the innermost layer, is on the lungs, whereas the parietal pleura, the outermost layer, is on the interior layer of the thorax.

what happens in meiosis during telophase l? A) sister chromatids are pulled apart. B) four haploid cells form from each parent cell. c) two haploid cells are formed. d)four retreads form in the center of the cell.
Two haploid cells are formed during Telophase I.
A nuclear sheath may form around the bundle of chromosomes. Some species, like human females, go through the first four phases of meiosis before giving birth to the germline cells. For some period, the germline cells are in telophase I. When the gamete is required for reproduction, there is a second round of division.The parent cell has two poles at Telophase I of the meiotic cycle, each with a full complement of haploid chromosomes (which still have their sister chromatids).Now, a cleavage furrow forms, separating the cytoplasm of the cell in two (a process ultimately called cytokinesis). The two daughter cells start preparing for the second meiotic division as soon as the cytoplasm has completely divided.Therefore, option (C) is correct.

%H₂0
15%
solute
80% H₂O
% solute
Correct. The solution in the beaker is hypertonic to the cell interior because its solute concentration is about 20%, which is greater than 15%. Water tends to leave the cell.
What are hypotonic and hypertonic solutions?When placing two solutions together separated by a membrane, we can classify them according to their solute concentration,
A hypertonic solution is the one with the higher solute concentration. It is the most concentrated solution.
A hypotonic solution has lower solute concentrations. It is the most diluted solution.
Isotonic solutions have the same solute concentrations.
In this example, we will assume the circle is a cell,
Cell interior ⇒ 85% water + 15% soluteBeacker solution ⇒ 80% water + 20% soluteThe solution in the beaker is hypertonic to the cell interior because its solute concentration is about 20%, which is greater than 15%.
The interior of the cell is hypotonic to the solution in the beaker, because it is more diluted. It has 85% water, which is higher than 80% water. Water tends to leave the cell moving forward to the beaker solution.

Describe two effects that a change in the sequence of amino acids would have on a protein.
Intricate molecules make up proteins.
The way a protein folds up determines the distinct three-dimensional form that it has. It cannot do its task in the cell if it does not fold up into the proper shape. Amino acid linkages, which are dispersed along the protein molecule, are what give a protein its shape. The bond cannot form if the incorrect amino acid is present, preventing the protein from adopting the proper shape and performing its function. For instance, the illness sickle cell anemia is brought on by a single fatal error in the amino acid sequence of the hemoglobin molecule!
Proteins are made from chemical 'constructing blocks' called amino acids. Your body uses amino acids to construct and repair muscle mass and bones and to make hormones and enzymes.
