The term teratogen refers to __________. Group of answer choices a limited time span during which a part of the body is biologically prepared to develop rapidly a synthetic hormone used to prevent miscarriage a rapid period of prenatal neurological development any environmental agent that causes damage during the prenatal period
Answers
The teratogen is any environmental agent capable of diverting development towards alteration during prenatal development.
What is teratogenic?They are those physical, chemical or biological agents, which by inducing some irregularity are usually the cause of congenital defects during normal embryonic and fetal development.The period of greatest danger is that of organogenesis, which includes the fourth to the ninth week of pregnancy.Therefore, we can conclude that an agent is teratogenic when it causes structural or functional alterations during prenatal period.

phospholipid bilayer
Answers
Answer:
Although the basic structure of biological membranes is provided by the lipid bilayer, membrane proteins perform most of the specific functions of membranes. It is the proteins, therefore, that give each type of membrane in the cell its characteristic functional properties. Accordingly, the amounts and types of proteins in a membrane are highly variable. In the myelin membrane, which serves mainly as electrical insulation for nerve cell axons, less than 25% of the membrane mass is protein. By contrast, in the membranes involved in ATP production (such as the internal membranes of mitochondria and chloroplasts), approximately 75% is protein. A typical plasma membrane is somewhere in between, with protein accounting for about 50% of its mass.
Because lipid molecules are small compared with protein molecules, there are always many more lipid molecules than protein molecules in membranes—about 50 lipid molecules for each protein molecule in a membrane that is 50% protein by mass. Like membrane lipids, membrane proteins often have oligosaccharide chains attached to them that face the cell exterior. Thus, the surface that the cell presents to the exterior is rich in carbohydrate, which forms a cell coat, as we discuss later.

Translate the word phrase into an algebraic equation: the quotient of 24 and 2 is equal to 12.
Answers
Answer:
24/2 = 12
Explanation:
(I'm pretty sure this isn't a Biology question, but I'll answer this because I'm nice.)
To translate English into algebriac equations, we have to understand what the symbols in algebra mean. Here are some we should know:
= : "equal to", "is", "equivalent to", etc.
> : "greater than"
< : "less than"
>= : "greater than or equal to", "at least"
<= : "less than or equal to", "at most"
We also have to know basic math operations:
a + b : "a added to b", "a plus b", "a combined with b", "a more than b", etc.
a - b : "a minus b", "b less than a", "b subtracted from a", etc.
a * b : "a multiplied by b", "a times b", "the product of a and b", etc.
a / b : "the quotient of a and b", "a divided by b", etc.
There are MUCH MORE examples of this, yet it becomes second-nature to change English sentences into algebra.
So, let's tackle the question. Sadly, it's pretty simple, so I won't really go in depth here. Since the quotient of a and b is a/b, the quotient of 24 and 2 is 24/2. We can also say that "is equal to 12" is "= 12". So,
24/2 = 12.
If one strand of a dna double helix has the sequence TATAGACGG what is the sequence of the other dna strand
Answers
Answer:
AUAUCUGCC
Explanation:
In DNA, the two strands are attached to each other by hydrogen bonding between the nitrogenous bases. The sequence of the other strand for the given strand: TATAGACGG is ATATCTGCC.
What is nucleotide base pairing?In DNA, two strands are present in the form of double helix which are held together in position by the help of hydrogen bonding. In DNA, four different nitrogenous bases are found. These are: Adenine, Guanine, Thymine, and Cytosine.
In DNA, each pyrimidine base pairs with a purine and vice versa. Adenine base pairs with thymine with the help of two hydrogen bonds and guanine base pairs with cytosine with the help of three hydrogen bonds.
So, each time an adenine comes opposite to a thymine and vice versa. Similarly, a guanine comes opposite to a cytosine and vice versa. This can be used to derive the sequence of the other strand for the given strand of DNA.
