● Ribosome structure/shape vsn snyone describe it and write down info about me
Answer:
Ribosome is sperical in structure, more prcisely like a burgar. It consists of 2 subunits, which in total are classified as 70s or 80s. It is its size, same like we measure an apples length with scale as 6cm(a rough example). As its burgar shaped, it consits gap between its 2 subunits. It makes a pathway for amino acid synthesis to occure as Rna molecules takes in codon to join with the complementry anticodon. Its function is protein synthesis.

Hemophilia is a disorder in which there is a failure in one of the steps of clot formation.What might be some advantages and disadvantages of this disorder?

Hemophilia can result in: Bleeding within joints that can lead to chronic joint disease and pain. Bleeding in the head and sometimes in the brain which can cause long term problems, such as seizures and paralysis. Death can occur if the bleeding cannot be stopped or if it occurs in a vital organ such as the brain. Complications of hemophilia can include: Deep internal bleeding. Bleeding that occurs in deep muscle can cause the limbs to swell. The swelling can press on nerves and lead to numbness or pain.

Which of the following is true of enzymes? Enzyme function is independent of physical and chemical environmental factors such as pH and temperature. Enzyme function is increased if the 3-D structure or conformation of an enzyme is altered. Nonprotein cofactors alter the substrate specificity of enzymes. Enzymes increase the rate of chemical reaction by lowering activation energy barriers. Enzymes increase the rate of chemical reaction by providing activation energy to the substrate.

when viewing particles under a microscope, you note that they are constantly bouncing around. this is described as
The constant movement of particles when seen under a microscope is a very common observation known as Brownian motion.
All particles are made of atoms. Atoms are comprised of three components:
NeutronsProtonsElectronsthe first two comprise the core of an atom, surrounded by a cloud of electrons.
Though much too small to be seen without aid, these atoms do indeed possess mass and are capable of colliding with one another. Particles constantly collide with one another and are bounced in the opposing direction, over and over again. This is precisely what we observe under the microscope as particles bouncing around and is referred to as Brownian motion.

what organ in the body regulates erythrocyte production?
Answer:
The hormone erythropoietin regulates enthrocyte production, which is produced in the kidneys.
Explanation:
Bone marrow is the body organ responsible for controlling erythrocyte (red blood cell) synthesis.
The process of erythropoiesis, which occurs largely in the bone marrow, produces erythrocytes. Hematopoietic stem cells, which can differentiate and develop into several types of blood cells, including erythrocytes, are found in the bone marrow.
The hormone erythropoietin (EPO), which is produced and secreted by the kidneys in response to low oxygen levels in the body, regulates the formation and release of erythrocytes. EPO stimulates the formation of erythrocytes in the bone marrow, maintaining an adequate supply of oxygen-carrying red blood cells in the bloodstream.

Answer:
All carbohydrates are made from smaller building blocks known as monosaccharides. Their main function is energy storage. The elements found in carbohydrates include Carbon, Hydrogen, and Oxygen
Explanation:
Carbohydrates are a fundamental organic compound that is essential to life. Their building blocks are known as monosaccharides, these are also known as simple sugars such as glucose. They all follow the same multiple of the unit C6H2O (1 C : 2 H : 1 O). We need to carbohydrates to store energy so that when we consume them we can perform cellular respiration, a highly precise process where we can break down glucose to form ATP for our body.
