Can someone help me?
Answer:
1. lytic/losigenic cycle
2. Restriction enzymes (breaks) and DNA ligase (joins)
3.mitosis (creation of twin daughter cells)
4. mitosis had helped humans with cell growth and repais (and keeps a steady supply of new cells)
Explanation:
it first goes through the lytic cycle where one bacterium inserts it's own dna into a host (human cell) and into the human DNA and it starts multiplying inside human cells in the lysogenic cycle

What is respiration and the types of respiration
Answer:
Hey mate......
Explanation:
This is ur answer.....
Respiration is the process by taking in oxygen and liberating carbon dioxide from the oxidation of complex organic substances.
Three types of respiration include internal, external, and cellular respiration. External respiration is the breathing process. It involves inhalation and exhalation of gases. Internal respiration involves gas exchange between the blood and body cells....

How is oxygen carried from your lungs into all of your cells for cellular respiration?
1. It slowly diffuses throughout your whole body from your lungs
2. It is carried by your red blood cells through your blood stream
3. Cellular respiration only takes place in the lungs, so you do not need to transport oxygen
4. Oxygen is not necessary for cellular respiration
Answer:
2. It is carried by your red blood cells through your blood stream.
Explanation:
The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell.
How does polyploidy allow speciation to occur in a single generation? Polyploid offspring produce gametes earlier in the mating season than than their diploid parents, causing reproductive isolation between the two generations. Polyploid offspring produce smaller gametes that disperse farther than the gametes of diploid parents, causing geographic isolation between the two generations. Physiological differences between polyploid offspring and their diploid parents allow them to thrive in different environments, causing geographic isolation between the two generations. Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.
Answer:
Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.
Explanation:
Speciation is an ecological and biological process through which new species are formed due to isolation.
In plants, polypoidy involves the possession of two complete sets of chromosomes and it leads to the origin of new species. Also, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).
As a result of the genomic differences between polyploid offspring and their diploid parents, this usually prevent them from successfully interbreeding and consequently causing reproductive isolation between the two generations.
5. Our nervous system and our skeletomuscular system help us react to stimuli. Give one example on how this helps us maintain homeostasis.
Answer
The nervous and skeletomuscular systems help maintain homostasis by regulating respiration.
Explanation:
The brain stem, consisting of the pons and medulla, represent the main respiratory center. According to Wikipedia, "an increased level of carbon dioxide in the blood, or a decreased level of oxygen, will result in a deeper breathing pattern and increased respiratory rate to bring the blood gases back to equilibrium."
This is an example of a homostastic response controlled by both of the organ systems referenced above.

how can a mutation in a gene affect the traits an organism has
Answer:
Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
Explanation:

Answer:
The gene will code for a different protein than it should.

Which of the following best explains how meiosis, followed by fertilization, ensures genetic variation?

What causes the formation of a cervical plug a testorone b progesterone c luteal d estroge e follicle
Answer:
b progesterone
Explanation:
The plug is formed as soon as there is implantation of fertilized eggs. The thickness of the cervical mucus becomes different as hormone levels changes in pregnancy.
The progesterone, encourages the production of thick fluid/ mucus which brings about the formation of a plug. This prevents bacteria from getting into the uterine cavity.
Answer: The correct option is B (progesterone).
Explanation:
The cervix is the ring of muscles also called the neck of the uterus in female reproductive system. This protrudes through the anterior wall of the vagina, opening into it at the external os.
After the fertilization of the ovum by the spermatozoa, the uterus prepares for the implantation which results from the secretion of hormones. Under the influence of oetrogen, secreted by the developing follicle, the cells of the endometrium divide rapidly causing the endometrium to build up and thicken.
While the viscosity of cervical mucus changes in response to hormone levels and during pregnancy, progesterone fosters the production of highly viscous mucus resulting in the formation of a plug that forms a physical barrier to bacteria and prevents their ascension into the uterine cavity. This plug is called CERVICAL PLUG.
The energy required to get a reaction started is called activation energy.

Explanation:
Genetically modified organisms include microbes used in biotechnology that possess enzymes promoting antibiotic resistance. This could be a problem given the rise of antibiotic-resistant organisms. However, these engineered microorganisms do not pose a risk to public health. What do you think prevents them from spreading antibiotic resistance to pathogens outside the laboratory
Answer:
What prevents these microorganisms from spreading resistance outside the laboratory is that they are modified to not survive outside the laboratory environment.
Explanation:
Antibiotic resistant microorganisms are very dangerous and unfavorable, as they leave living beings completely completely defenseless to their attacks. However, there are microorganisms that have been modified in the laboratory, as shown in the question above, and do not present any risk to living beings, even if they develop resistance. This is because the modification that these microorganisms received makes them not survive the environmental conditions outside the laboratory, which causes them to die if they leave the laboratory.

You have learned that scientists have found physical evidence of the Flood. In this project you will think about Noah and his construction of the ark.
Pretend that you are a newspaper reporter, and you are able to interview Noah. Then write a newspaper article about your interview.
Answer these questions.
What kinds of questions would you ask him?
Write a news article on your interview with Noah. (100 words or more is fine)
Need help asap just answer write the article the first 1 i already answered just copy pasted the questions
Answer:
We got a chance to speak to Noah the Ark builder. Many people of the town have been wondering what Noah has been building lately. We asked him what was his objective and he said "A great flood like no other will come, water from the sea will fall from the air. Whoever is in the ark shall be safe. Two of each type of animal on earth shall come to my ark for shelter. The storm will be so great it will knock out all who does not inhabit the ark."It is hard to understand what he means by these statements but who knows maybe his boat will take him somewhere. The people of the town have been calling him insane, since no one would need a boat that big.
(I'm guessing that you mean the interview was before the flood since everyone died after.)
