Okazaki fragments are formed on which strand?
Answer:
The leading strand is continuously synthesized and is elongated during this process to expose the template that is used for the lagging strand (Okazaki fragments). During the process of DNA replication, DNA and RNA primers are removed from the lagging strand of DNA to allow Okazaki fragments to bind to.
Explanation:
Hope it helps
b) The frequency of allele A, is 0.3 or 30%. Does this mean that 30% of the individuals in the
population will have an A, phenotype? (1 point)
Answer:
no because 0,3 is 3/10 and not 30$

Which of these phylogenetic trees depicts a different evolutionary history than the others?
A. Tree 1
B Tree 2
C tree 3
D tree 4
Tree 3 depicts a different evolutionary history than the others. So, the correct option is C.
What is Phylogenetic relationship?A phylogenetic tree is defined as a branching diagram or a tree that shows the evolutionary relationships between different biological species or other entities based on similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree that points to common ancestry.
These relationships are identified by using the similarities in DNA, RNA, or protein sequences, or by comparing the anatomical features. Through this, we get to know that all life arises from a common ancestor. In the above given information, Tree 3 shows the phylogenetic relationship.
Thus, Tree 3 depicts a different evolutionary history than the others. So, the correct option is C.

Parent strand of DNA is CCTAGCT. What is the complementary strand?
Answer:
GGATCGA
Explanation:
Adenine goes with thymine and Cytosine e goes with guanine.
Basically A is with T; C is with G
Note that:
C matches with G
T matches with A
In this case, the strand of DNA given is CCTAGCT. The complementary strand would therefore be GGATCGA.
~
A DNA base sequence of ACAGTGC would code for
Answer:
TGTCACG
Explanation:
Using Chargaff's rule:
A=T
G=C
It can give you the complimentary strand.
For the situation below , determine whether the premium will likely increase , decrease, or remain the same. Jamie just turned 25
Answer:
The premium decreases when Jamie turns 25 years old.
Explanation:
The question above is about auto insurance premiums, which, as the name already says, is insurance aimed at automobiles, with the objective of promoting economic and financial protection in relation to accidents and problems that may happen in these vehicles.
When an individual turns 25, like Jamie, the insurance premium decreases in value, that is, the insurance companies offered cheaper and more economical rates to the driver when he is going to renew the contract.

Explain how organisms contribute to the
creation of soil.
Explanation:
Soil formation is influenced by organisms (such as plants), micro-organisms (such as bacteria or fungi), burrowing insects, animals and humans.
As soil forms, plants begin to grow in it. The plants mature, die and new ones take their place. Their leaves and roots are added to the soil. Animals eat plants and their wastes and eventually their bodies are added to the soil.
This begins to change the soil. Bacteria, fungi, worms and other burrowers break down plant litter and animal wastes and remains, to eventually become organic matter.

explain what is crossing-over in your own words
Explanation:
it occurs during meiosis. Its the exchange of chromosome pieces between the non-sister chromatids during the production of gametes.
Answer:
Crossing-Over is a DNA segment on each chromosome section may code for eye color, although one chromosome may code for brown eyes and the other for blue eyes. Crossing over occurs most often between different alleles coding for the same gene.
Explanation:
Which of the following best describes the principle of independent
assortment?
Answer:
Law that states that the segregation of any pair of alleles is independent of any other pair of alleles . As a result each pair of gametes receives one member of every pair of alleles.no influences from other alleles is necessary.

adaptation would decrease the competition
between them?
Answer:
One eats during the day and the other eats at night.
Explanation:
Answer:
Well, it really depends on the type of animal (for example water, land). However an adaptation like being able to eat different foods would decrease competition between them as they don't have to hunt the same prey.
