So the problem ask to choose among the following choices that has the factor of f(x) if a polynomial function f(x) has a roots 4-13i and 5, base on that, the answer is not in the choices, base on my computation, the answer is f(x) = (x-y+13i)(x-5), I hope you are satisfied with my answer
Answer:
B There will be blue colonies only
Explanation:
This screen in called the blue white screening. This is a rapid test that allows scientist to check for their insert of choice in the colonies at a glance. The concept is that where the insert is located the <em>lac Z </em>gene in the vector is interrupted and therefor Xgal, a reporter can be produced. Where there are blue colonies being formed the plasmid has self-ligated and the <em>lac Z</em> gene is not interrupted and the X-gal can be formed rendering a blue color.
Answer: 5. Amoebocytes have a variety of functions: delivering nutrients from choanocytes to other cells within the sponge, giving rise to eggs for sexual reproduction (which remain in the mesohyl), delivering phagocytized sperm from choanocytes to eggs, and differentiating into more-specific cell types. 6. Sponges form symbiotic relationships with a variety of microorganisms, including bacteria and algae. A symbiotic relationship between organisms is a close ecological association between two species that may be mutually beneficial or may benefit one partner at the expense of the other. However, humans are still damaging sponge populations with weighted nets and even taut fishing lines, which can slice sponges apart by accident. As a rule, anything that can affect the ocean floor will have a negative impact on sponges, as they have never developed protection against impacts. brainliest??

<span>Challenges:
1. Vietnam
2. The worst economy since the Great Depression
3. Communist Europe (the Helsinki Accords)
4. Richard Nixon
One month after taking over the presidency, Ford pardoned Nixon. This
caused a lot of controversy but Ford claimed he did it to save the
nation from the prospect of a long, messy, and divisive trial.
In 1974, President Ford also offered clemency to those who evaded the
draft during the Vietnam War if they would swear allegiance and perform
two years of public service. Similarly, those who deserted during the
war could return for two years in the branch they left to achieve
clemency. However, Ford was criticized both by those who felt he was
being to easy on the draft dodgers and those who had avoided the service
because they felt they were in the right.
In 1974, Ford asked for aid to be sent to South Vietnam as fighting had
resumed. Congress would not agree. In April 1975, Saigon fell and by
1976, North and South Vietnam were united into one country.
Ford escaped two assassination attempts, both by women. First on
September 5, 1975, Lynette Fromme, a follower of Charles Manson, pointed
a gun at him but did not fire. She was convicted of attempting to
assassinate the president and sentenced to life in prison. The second
attempt on Ford's life occurred on September 22, 1975 when Sara Jane
Moore fired one shot that was deflected by a bystander. Moore was trying
to prove herself to some radical friends with the assassination of the
president. She was convicted of attempted assassination and sentenced to
life in prison.</span>
Answer: Imagine life without your best friend. Who would you hang out with and talk to about your problems? Life would be so lonely! You rely on your friends for companionship, fun, and support. Animals rely on each other, too. Some have lifelong relationships with other organisms, called symbiotic relationships. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism.
Mutualism: both partners benefit. An example of mutualism is the relationship between the Egyptian plover and the crocodile. In the tropical regions of Africa, the crocodile lies with its mouth open. The plover flies into its mouth and feeds on bits of decaying meat stuck in the crocodile’s teeth. The crocodile does not eat the plover. Instead, he appreciates the dental work. The plover eats a meal and the crocodile gets his teeth cleaned. Coincidentally, the Egyptian plover is also known as the crocodile bird.
Commensalism: only one species benefits while the other is neither helped nor harmed. For example, remora fish are very bony and have a dorsal fin (the fin on the back of fish) that acts like a suction cup. Remora fish use this fin to attach themselves to whales, sharks, or rays and eat the scraps their hosts leave behind. The remora fish gets a meal, while its host gets nothing. Selfish, sure, but neither gets hurt.
Parasitism: One organism (the parasite) gains, while the other (the host) suffers. The deer tick is a parasite. It attaches to a warmblooded animal and feeds on its blood. Ticks need blood at every stage of their life cycle. They also carry Lyme disease, an illness that can cause joint damage, heart complications, and kidney problems. The tick benefits from eating the animal's blood. Unfortunately, the animal suffers from the loss of blood and nutrients and may get sick.
