Answer:
Some species that already have or that developed cold-weather adaptions through natural selection will survive, while species without cold-weather adaptations may go extinct.
Explanation:
That was the answer in study island :/
A good example of gene cloning would be, breeding 2 dogs that are the same breed and have good characteristics to have similar outcome.
Ovary, uterus
Uterus, fallopian tube
Uterus, ovary
B? or D? Or something else?
Answer: Ovary, uterus
Explanation:
The ovary is a female reproductive structure. It is responsible for development and secretion of egg (ovum) at the time of fertilization. It is responsible for secretion of hormones which are important for menstrual cycle and fertility.
The egg from the ovary is released into the fallopian tube. The egg from the fallopian tube is fertilized in the uterus by one of the sperm cell.
The enzyme DNA polymerase is responsible for linking the nucleotides in a new DNA strand.
Before replication of DNA occurs, the DNA double helix is first unwound, after which the two strands must be separated much like the two sides of a zipper by breaking the weak hydrogen bonds that link the paired bases.
The unwound DNA strands are held apart to expose the bases so that new nucleotide partner can hydrogen-bond to them. It is DNA polymerase that moves along the exposed strand, joining newly arrived nucleotides into a new DNA strand by linking paired bases by hydrogen bonds.
DNA polymerase is the enzyme that adds nucleotides to a new DNA strand, facilitating the hydrogen bonding between these nucleotides and their complements on the template strand. However, it's not responsible for the actual hydrogen bonding--it simply places the nucleotides in the right positions for bonding to occur. The replication process is completed when DNA ligase seals the gaps between Okazaki fragments on the lagging strand.
The enzyme responsible for facilitating the hydrogen bonding between nucleotides in a new DNA molecule is DNA polymerase. This enzyme adds nucleotides in the 5'-3' direction during DNA replication, matching each nucleotide to its complementary base on the template strand. It's important to note that DNA polymerase doesn't actually form the hydrogen bonds between the base pairs. Rather, it positions the nucleotides in such a way that they can form hydrogen bonds with their complements on the template strand.
The process begins when the DNA molecule is opened up by other enzymes, breaking the hydrogen bonds between the nitrogenous bases. Once separated, DNA polymerase begins to add nucleotides to the growing strand. Hydrogen bonds then form between the base pairs, but DNA polymerase isn’t responsible for this bonding—it simply places the nucleotides in the proper positions for these bonds to occur.
Finally, DNA ligase seals the gaps between Okazaki fragments on the lagging strand, creating a continuous DNA strand. This process of nucleotide addition, hydrogen bonding, and ligation allows for the replication of the double-stranded DNA molecule, with each new molecule containing one original strand and one new strand.
#SPJ6
B.)empty set
C.)the set of whole numbers less than one billion
D.)the set of natural numbers
E.)none of the above
Answer: the correct answer is D) The set of natural numbers.
A set that contains infinite number of elements is called as infinite set.
Natural numbers are those that start from one and go till infinity. Thus, set of natural number is infinite as this set contains infinite number of elements, satisfying the property of infinite set.
On the contrary, option A), B), and C) contains finite numbers, which can be counted. Thus, they are not the example of infinite set.
Thus, D) is the right answer.
Answer;
D.)the set of natural numbers
Explanation;
-A set is said to be an infinite set whose elements cannot be listed if it has an unlimited (i.e. uncountable) by the natural number 1, 2, 3, 4, ………… n, for any natural number n is called a infinite set. A set which is not finite is called an infinite set.
-Set A cannot be infinite because it only goes to 100 and Set B is empty so that also has nothing infinite. However set of Natural numbers as they continue number by number getting in to an bigger number is infinite.
-On the other hand; A set is said to be a finite set if it is either void set or the process of counting of elements surely comes to an end is called a finite set.
