Prometaphase :
-Shaft strands connect to chromosomes
-Chromosomes consolidate
Metaphase:
-Chromosomes adjust at the metaphase plate

Ribosomes assemble _____ to make proteins.
A) DNA
B)amino acids
C) nucleic acids
D) RNA
The right option is; B)amino acids
Ribosomes assemble amino acids to make proteins.
Ribosomes are cell organelles found within all living cells. Within a cell, ribosome may be bound to the endoplasmic reticulum, or it may be suspended in the cytosol. Ribosomes functions as the site of biological protein synthesis. They are responsible for assembling amino acids in the order specified by messenger RNA (mRNA) molecules. Ribosomes contain two parts; (i) the small ribosomal subunits (that read the RNA), and (ii) the large subunits, (that link amino acids to create a polypeptide chain).
Ribosomes assemble RNA to make proteins. therefore option D is correct.
Ribosomes are responsible for the assembly of amino acids into proteins. This process, called protein synthesis or translation, occurs within the ribosomes in the cytoplasm of the cell.
During protein synthesis, the genetic information stored in DNA is first transcribed into RNA molecules, specifically messenger RNA (mRNA). The mRNA carries the instructions for building a specific protein from the DNA in the nucleus to the ribosomes in the cytoplasm.
Once the mRNA reaches the ribosomes, it serves as a template for protein synthesis. Transfer RNA (tRNA) molecules, which are specialized RNA molecules, bring the corresponding amino acids to the ribosome.
The sequence of nucleotides in the mRNA determines the sequence of amino acids to be joined together.

which sequence shows the transfer of oxygen for use by the body ?
The right answer is D.
Breathing is the process by which oxygen from the air gets into your lungs and gets into your body. Our lungs take oxygen from the air and carry it into our bloodstream, which carries it to the cells, tissues and organs that allow us to walk, talk and move.
Our lungs also remove carbon dioxide from our blood, through the air we breathe.

The inferior vena cava brings blood from the lower regions of the body and empties into the:
The inferior vena cava empties deoxygenated blood from the lower body into the right atrium of the heart. Option B is correct.
The large vein known as the inferior vena cava returns oxygenated blood from the lower body to the right atrium of the heart. This is important for the foundational venous return, where both the sub-par vena cava and the predominant vena cava void their blood into the right chamber, guaranteeing that the blood is then shipped off the lungs for oxygenation. It's memorable's vital that the heart has four chambers: two atria and two ventricles. The left atrium receives oxygenated blood from the lungs, while the right atrium receives blood that has been deoxygenated from the body.Complete question as follows:
The inferior vena cava brings blood from the lower regions of the body and empties into the ______. A. left atrium. B. right atrium. C. right ventricle.
What defines a macromolecule as a lipid
An:
All lipids are sold fats
A lipid is defined as a macromolecule by its specific characteristics, which include being hydrophobic, soluble in nonpolar substances, and having a high energy content due to long hydrocarbon chains. They serve vital biological functions, such as energy storage, cell signaling, and forming structural components of cell membranes.
Explanation:A macromolecule is defined as a lipid by its distinct physical and chemical properties. Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, and others. The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.
Lipids are characterized by their inability to dissolve in water (they are hydrophobic). This is because they are made up of hydrocarbon chains, which are non-polar and thus repel water molecules. In contrast, they are soluble in nonpolar substances and organic solvents.
Lipids also have a high energy content. This is because the long hydrocarbon chains they contain are rich in energy-releasing carbon-carbon and carbon-hydrogen bonds. The body can use lipids as an energy reserve, with fat serving as a more efficient storage form of energy than carbohydrates.

Hormones play an important role in regulating blood glucose levels. what is an example of this?
Insulin and glucagon, hormones secreted by the pancreas, are prime examples of how hormones regulate blood glucose levels. They act together to keep a balanced glucose level in our blood.
Explanation:Yes, hormones play a significant role in the regulation of blood glucose levels. The prime example is that of insulin and glucagon, hormones secreted by the pancreas. Essentially, when blood sugar levels rise, the pancreas releases insulin which facilitates the transport of glucose from the blood into the cells of the body. This reduces high blood glucose levels. In contrast, when blood sugar levels fall, glucagon is released by the pancreas and instigates the conversion of stored glycogen into glucose, which is then released into the blood. This mechanism illustrates the delicate balance our bodies maintain to regulate blood glucose levels.

Chemical reaction equations, such as the one for photosynthesis, show the reactants and products of a reaction. How does this simplification misrepresent what takes place during the process of photosynthesis?
It does not show where in a cell photosynthesis occurs.
It does not show how long photosynthesis takes to happen.
It does not show that photosynthesis consists of many separate reactions.
It does not show the number of molecules required to produce glucose.
The right answer is It does not show that photosynthesis consists of many separate reactions.
It takes six molecules of carbon dioxide and six molecules of water to synthesize a molecule of glucose, releasing six molecules of oxygen, thanks to the light energy.
6 CO2 + 6 H2O + light energy ==> C6H12O6 (glucose) + 6 O2
But this balance is in fact broken down into two successive stages:
Light phase or photochemical phase:
12 H2O + light ==> 6 O2 + chemical energy (24 H).
The Calvin cycle (dark phase):
6 CO2 + chemical energy (24 H) ==> C6H12O6 + 6 H2O.

D: A desert coyote population develops the increased ability to cope with low water conditions
Explanation:
Adaptations are any behavioral, functional or structural changes in organisms that help in their survival in their respective habitat. Desert habitat is characterized by extremely higher temperatures and water scarcity. Development of any adaptive feature that help the desert coyote population to withstand the lower water availability would increase its survival in desert habitats.
