The time during fetal growth when specific parts or organs develop is known as ________.
The time during fetal growth when specific parts or organs develop is known as the critical period.
Fetal Development: Growth Stages The egg that will become your baby rapidly divides into several cells within 24 hours of fertilization. The embryo turns into a fetus by the eighth week of pregnancy. A typical pregnancy lasts for about 40 weeks. Three trimesters are created out of these weeks.
The fourth through sixth months of your pregnancy will see significant fetal development spurts, which will cause you to put on a lot of weight. Your pre-pregnancy BMI and if you are carrying multiples will affect how much weight you gain. During your pregnancy, you may put on between 11 and 54 pounds.

What are the first three amino acids coded by this new mutated sequence
The first three amino acids coded by this new mutated sequence are Glutamine, Alanine, and Lysine.
One triplet nucleotide is coded for by one amino acid. Therefore, there are 16 nucleotides altogether following the insertion of the adenosine residue. The mRNA sequence will thus encode five amino acids. A codon is a collection of three nucleotides that are found in mRNA, and each codon designates an individual amino acid (hence, it is a triplet code). Thus, the chain of amino acids that makes up a protein is assembled in accordance with the template provided by the mRNA sequence and this is how Glutamine, Alanine, and Lycine form.
A gene encodes the amino acid composition of a polypeptide. The polypeptide's amino acid composition is determined by the bases in the gene's DNA. Proteins can either have a single polypeptide or many polypeptides linked together. All of a cell's or an organism's generated proteins are found in the proteome. A codon is a group of three DNA or RNA nucleotides that specify an amino acid or serve as a signal to cease protein production.

Compare and contrast semidiurnal tides, mixed semidiurnal tides and diurnal tides.
It is called a semi-daily or semidiurnal tidal pattern when the heights of the two highs and lows are roughly equal whereas a mixed semidiurnal tidal pattern is one in which the heights of the high and low tides vary. It is called a diurnal tide when areas have only one high and one low tide each day.
Since "diurnal" refers to a daily occurrence, a tide is said to be diurnal if there is just one whole tidal cycle every day. In the Gulf of Mexico, on Alaska's west coast, and in some regions of Southeast Asia, diurnal tides are typical.
Semidiurnal refers to "half of a day," and as one tidal cycle lasts for half a day, there are two full cycles per day. The majority of Europe, the west coast of Africa, the east coast of North America, and Australia all experience semi-daily tides.
The differences in height in mixed semidiurnal tides may be the result of amphidromic circulation, the angle of the moon, or any of the other variables. They are found along the Pacific coast of North America.

several factors account for the movement of water up xylem vessels. which single factor is most important in pulling water toward the top of a tall tree?
The single most important factor in pulling water towards the top of a tall tree is the evaporation of water through the stomata.
Xylem vessels are vessels that transport water from the roots of the plant to the leaves to be used for photosynthesis. The process is somewhat easier for short plants and shrubs as their leaves are close to the ground and the water doesn't need to travel very far to reach the leaves. For tall plants however, it's quite different.
The cohesive and adhesive properties of water enable tall plants to pull water from their roots. adhesion makes water molecules stick to the walls of the xylem vessel, and cohesion makes water molecules stick together. A combination of the two brings about capillary action, which accounts for the movement of water up xylem cells. However, this is not the most important factor.
Capillary action alone can only pull water about halfway through the xylem of tall trees before coming under the influence of gravity. When water evaporates from the stomata in the leaves, it creates a kind of vacuum in the xylem. This effect pulls water from the roots all the way to the leaves, hence, the important factor in pulling water towards the top of a tall tree is the evaporation of water through the stomata.

The right reason to why the P waves and S waves are not received in the shadow zone is because P waves are refracted and S waves are absorbed in the earth's outer core.
As they move further into the Earth's mantle, P waves and S waves move faster.
Curvilinear pathways are followed as they move through the Earth, but when they cross the barrier between substances in various states, they abruptly shift course.
However, P waves can go through the liquid outer core but S waves cannot. Because of the Earth's changing density, waves are refracted as they pass through it. As a result, the waves follow curved pathways. Refraction causes an abrupt shift in direction of the waves when they cross the boundary between two separate layers.
What are the differences between P waves and S waves?
P waves can pass through solids, liquids, and gases, but S waves can only pass through solids. The structure of Earth can be determined by scientists using this information.

Germs and contaminants can contaminate drinking water at the source or in the distribution system after the water has been treated. Some of the sources through which dangerous bacteria and chemicals could infiltrate rivers include fertilizers, pesticides, or other chemicals that have been used to treat land close to waterways.
Dangerous microorganisms that may be present in contaminated water include the following:
GiardiaSalmonellaCrypstosporidiumEcoliLegionellaThe spread of diseases like cholera, diarrhea, dysentery, hepatitis A, typhoid, and polio is only one of the problems that contaminated water and poor sanitation may cause. People face avoidable health risks when water and sanitation facilities are insufficient, poorly managed, or unavailable.
Drinking contaminated water can expose one to bacterial, viral, and protozoal illnesses.
Many of these are pathogens, which after consumption can swiftly send a person to the hospital.

Estimate daily energy needs for an active 60 kg man to gain weight and a 70 kg sedentary woman to lose weight
Women: BMR = weight in kilos x 2 x 11.
Men: BMR = weight in kilos x 2 x 12.
An active 60 kg woman's daily energy requirements for weight loss are 2,027 divided by 0.85, or 1,723 kcal.
An energetic 60 kg man needs 2,027 x 1.2 = 2,432 kcal per day to gain weight.
How do you calculate energy based on weight and age? The PAL value by the BMR, they were transformed into energy units (i.e. joules and calories). Requirements were divided by the weight employed in the equations to predict BMR in order to express them as energy units per kilogram of body weight. This computation is illustrated by the example given below for a population of females who lead a moderately active lifestyle and have a mean body weight of 70 kg:As a rule of thumb, BMR uses 11 calories for every 0.5 kg of a woman’s body weight and 12 calories per 0.5 kg of a man’s body weight.
Women: BMR = weight in kilos x 2 x 11 (alternatively weight in pounds x 11)
Men: BMR = weight in kilos x 2 x 12 (alternatively weight in pounds x 12)
Example: BMR for a 60 kg woman = 60 x 2 x 11 = 1,320 kcal.
You can either multiply the number above (maintenance calorie needs) by 0.85 or reduce your daily calorie consumption by 15%. A weekly fat reduction of roughly 0.5 kg will result from this. An active 60 kg woman's daily energy requirements for weight loss are 2,027 divided by 0.85, or 1,723 kcal.
The preceding number (maintenance calorie needs) should be multiplied by 1.2 or increased by 20% everyday. Expect a weight increase of 0.25–0.5 kg per month when combined with a resistance training regimen. An energetic 60 kg lady needs 2,027 x 1.2 = 2,432 kcal per day to gain weight.
