DNA replication is said to be semiconservative. Which of the following statements correctly explains what this means?
Answer: DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands.
This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.

Hope this helps :D
The semi-conservative nature of DNA replication illustrates that each strand in the DNA double helix function as a template for the synthesis of a new or complementary strand.
What is DNA replication?DNA replication may be defined as a type of biological process that deals with the synthesis of two identical replicas of DNA from one original DNA molecule during cell division.
The semi-conservative model of DNA was proposed by Watson and Crick. This model implies that each double helix of DNA is composed of one new and one old strand.
In semi-conservative replication, the parental double helix is half conserved and each parental single strand remains intact.
Therefore, DNA replication is said to be semi-conservative due to the process of each new double strand consisting of one parental strand and one new daughter strand.

Speckled trout and red drum both prey on mullet along the Texas coastline. Dead zones are caused by excessive nutrient pollution, along with other factors that deplete the oxygen from the water. What likely effect would increasing dead zones have on the populations of speckled trout, red drum, and mullet?
Answer:
All Three Populations Would Decrease
Explanation:
Dead zones have little to no life in them, and besides the fact that this would mean the popoulations of all of them would just be down because of this, mullet will die out due to nothing to feed on, which will make drums and trout also die out, so all of the populations would go down.
The effect that would be increasing dead zones have on the populations of speckled trout, red drum, and mullet is that the population of all three species would get decrease.
What do you mean by Prey?Prey may be defined as an animal that is hunted and killed by another for food.
Dead zones lead to a decline in biodiversity of that area, due to the excessive nutrient pollution and depletion of oxygen. If the members of mullet species get reduced in an environment, species of speckled trout and red drum feel the shortage of food, and hence they also get eliminated or die from the surrounding.
Therefore, the effect that would be increasing dead zones have on the populations of speckled trout, red drum, and mullet is that the population of all three species would get decrease.

Answer:
it may affect the animals and other tree's.
Explanation:
it may affect animals because since it is a new tree, you might not know that it may be harmful for some animals, like maybe the berries the produce are poisonous or fruits some animals are forbidden to eat. this may be a problem because some animals may accidentally eat that fruit and possibly be injured or die.
trees need sunlight and food, if another tree hopes in suddenly there would be more competition for sunlight and water, there may also be not enough water and sunlight for all the trees to share. this is a problem because if the trees can't get enough sunlight and water, they would die and this leads to a broken home for the animals living in that tree.

Answer:
Polymerase chain reaction machine
Primers
Petri dishes
Test tubes
Pipettes
DNA Polymerase
Free nucleotides
The organism to be identified
Explanation:
To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study.
To carry out this identification, items used include; primers, the PCR machine, test tubes, DNA polymerase, free nucleotides, etc.

Explanation:
Tom walked into your office and said he'd been looking forward to talking with you. He said, "I've been feeling really good lately, really good...powerful, strong." Tom, a 54-year old man, was smiling and a bit wide-eyed as he began the conversation. "I'm feeling a real sense of purpose, like I was put here to help people," he said. Tom got further into his recent revelations, going so far as to say he felt "like Jesus Christ, in a way." Tom stood up with excitement as he continued to escalate emotionally and with his gestures. At no point was he threatening, but he was far more animated than ever before. As the conversation progressed, Tom told you that he was thinking about you and how powerful you were, too. He said you were like Thor with his hammer and that the two of you could really do good in the world. Then, giggling and gleeful, he admitted that he was thinking that he actually was Jesus Christ and that he wanted you and your powerful hammer to help him save humanity from those who were trying to control him.

clasificatoin of hormones
Answer and Explanation:
Hormones are substances that administer the human body having several different and essential functions for the proper functioning of the body. There are several different types of hormones and they are classified into four groups called peptides, steroids, amines and eicosanoids.
Peptides are hormones that have 3-20 amino acids. Among these hormones we can mention insulin, glucagon and somatostatin.
Steroids are hormones produced from cholesterol. Among them we can mention Cortisol, Aldosterone and Testosterone.
Amine hormones are those that are released into the thyroid and adrenal glands. These hormones circulate freely in the blood. Among them are epinephrine and norepinephrine.
Eicosanoids are the hormones derived from arachidonate. Among them are the hormones called prostaglandins, thromboxanes and leukotrienes.
