During the second and third trimesters, pregnant women should gain approximately one pound per week.
Pregnancy is the condition of conceiving a baby wherein a baby is being nourished inside the body of the female (inside the womb of the mother). Weight gain depends in part on your body mass index before pregnancy. Pregnant women usually gain more weight in their second trimesters than in their third trimester. In general, a healthy women needs about 340 additional calories per day during the second trimester. Sweets and fats should be kept to a minimum in the diet. A good consumption of fruit and vegetables should be included because it provides vitamins and minerals needed for the growth of the baby.

which cell organelle is most responsible for supplying energy to the cell?; which list of characteristics describes organisms classified as animals?; what is the cell wall made of
To carry out this crucial activity, cells have specialized organelles that supply the cell with energy. We refer to this particular organelle as mitochondria.
The organelle that gives a cell its energy is called mitochondria. The mitochondria store metabolites, break down large molecules and then recycle them.
An organelle called a mitochondrion can be found in the cells of the majority of Eukaryotes, including mammals, plants, and fungi. Adenosine triphosphate (ATP), produced by aerobic respiration in mitochondria and used as a source of chemical energy throughout the cell, is produced by mitochondria using their double membrane structure.
They were found in the voluntary muscles of insects by Albert von Kölliker in 1857. Carl Benda first used the term "mitochondrion" in 1898. The phrase "powerhouse of the cell" was popularized by Philip Siekevitz in a 1957 essay of the same name and is often used to refer to the mitochondrion.

What increases rate of protein synthesis?; What controls the rate of protein synthesis?; What organelle has a high rate of protein synthesis?; What is protein synthesis rate?
For boosting protein synthesis, timing of protein ingestion is crucial. Consuming protein right after after working out boosts protein synthesis, however waiting even two hours dampens the reaction.
Translation initiation controls, in part, the rate of protein synthesis by interacting with a 40S ribosomal subunit to bind the initiator tRNA (met-tRNAi) and messenger RNA (mRNA). Protein synthesis can become constrained by the met-tRNAi or mRNA binding steps, respectively.
The crucial cell organelles involved in protein synthesis are called ribosomes. The proper operation of the cell depends on proteins. Proteins and RNA found in ribosomes assist in translating genetic code into proteins. The two subunits of ribosomes are smaller and larger subunits.
In conclusion, human basal fractional protein synthesis rates for muscle, tendon, bone, cartilage, ligament, and menisci range from 0.02 to 0.13% per hour.

Arthropods, which means "joint" in Ancient Greek, are invertebrate organisms with a segmented body, an exoskeleton, and paired jointed appendages. The phylum Arthropoda is made up of arthropods. Their jointed limbs and chitin-based cuticle, which is frequently mineralized with calcium carbonate, set them apart.
The arthropod's body is divided into segments, each of which has two appendages.
Arthropods have an external skeleton and are bilaterally symmetrical. They must go through many stages of moulting, a process through which they lose their exoskeleton to reveal a new one, in order to continue growing. Certain species possess wings.

During skeletal muscle cell contraction, insulin may attach to its receptor on the cells' surface via an insulin-dependent mechanism or while the cells are at rest. Depending on the body's requirements, the liver produces and stores glucose. The hormones insulin and glucagon are principally responsible for signalling the need to store or release glucose.

About one half of all children whose lack of conscience becomes plain before age 15 become antisocial adults .
A boy with an antisocial personality disorder, often known as a sociopath or psychopath, is frequently one who begins to lie, steal, fight, or engage in unrestricted sexual behavior before the age of 15.
Criminal behavior, which affects around half of children, is not a significant part of antisocial behavior, despite its remorseless and even illegal actions. The reason for this is that criminals truly show concern for their friends and families. Antisocial people take rash actions and show little emotion or fear.
Antisocial behavior is more likely to be committed by people with cold attitudes because genetic factors help shape the brain, typically in conjunction with child abuse.
According to studies, murderers had less activity in their frontal lobes, an area of the brain that controls impulses. Further investigation indicated that the frontal lobe tissue of violent recurrent offenders was 11% lower than anticipated.

Transcription of the lac operon will not occur in the presence of lactose
With lactose in the cell, lactose binds to the repressor. This causes a structural change in the repressor and it loses its affinity for the operator. Thus RNA polymerase can then bind to the promoter and transcribe the structural genes
Most mutations in the operator, the binding site for repressor, lead to lower affinity for the repressor and hence less binding.
A mutation occurring in the lac I gene causes the inability of the repressor to bind with the operator. If the repressor does not bind the operator, RNA polymerase will move to the transcription site and do transcription even if lactose is absent.
