Which of the following phrases incorrectly finishes this statement? a genetic disease that causes death in infancy and has an autosomal recessive inheritance pattern can persist in a population because.
The phrase which incorrectly finishes this statement is that if both parents are carriers, they have a 50% chance of having normal children.
What is an Autosomal recessive disorder?This is the type of disorder which involves two copies of the mutation being sufficient enough to cause the disease.
If both parents are carriers, then the chance of having normal children is zero and not 50 percent.

How do vaccines work if the pathogen in them is dead?
Answer:
Inactivated vaccines use the killed version of the germ that causes a disease.
Inactivated vaccines usually don't provide immunity (protection) that's as strong as live vaccines. So you may need several doses over time (booster shots) in order to get ongoing immunity against diseases.

Even-aged management practices involves clearing trees that
are all the same height
b. are all the same weight
C. are all near the same age
d. are all of widely different ages
Please select the best answer from the choices provided
Answer: C. Are all near same age.
Explanation: Even-aged firewood management practices refer to the practice of clearing of trees that "are all near the same age"as this technique is usually adopted to maintain the proportion and continuity of various species of trees(thus, cutting of the trees of same age). This practice is employed to minimize the costs and attain a coeval and comrade group of trees. It proves quite beneficial in reestablishing the succession of a native breed. It involves the selection of trees at first depending on the size, desirable species, etc. followed by clearcutting of unmerchantable(undesired) trees. This technique is usually adopted to maintain the proportion and continuity of various species of trees.
Nathan is comparing the cells from a species of amoeba with a species of bacteria. Both species are unicellular, meaning individuals exist as a single cell. Which characteristic of the cells should Nathan expect to be the same in both species?
A. The size and shape of the cell
B. The method of reproduction, or making more cells of the species
C. The organization of DNA into structures such as chromosomes and the cell nucleus.
D. The genetic code that has used by DNA and RNA to direct protein synthesis
Given what we know, we can confirm that Nathan can expect the means of reproduction to be the same in both species, meaning that the correct answer would be option B.
Why is option B the correct choice?When dealing with unicellular organisms, many aspects will always remain the same between the distinct species. One such aspect is the reproduction method used universally by all unicellular species, that being reproduction through binary fission. The organism replicates its DNA and then divides into two identical cells.
Therefore, we can confirm that Nathan can expect the means of reproduction to be the same in both species, meaning that the correct answer would be option B.

Homologous chromosomes may exchange segments; this is called crossing over. crossing over increases genetic variability. when does crossing over occur?
A trade of chromosome segments among non-sister homologous chromatids happens and is referred to as crossing over.
Crossover happens while chromosomes, usually homologous times of the equal chromosome, spoil after which reconnect however to the specific quit piece. If they spoil on the equal location or locus withinside the collection of base pairs, the end result is an trade of genes, referred to as genetic recombination.
What are homologous chromosome?Homologous chromosomes are made from chromosome pairs of about the equal length, centromere position, and marking pattern, for genes with the equal corresponding loci.

Suppose a new resort hotel is built on a hawksbill sea turtle nesting site, and hotel guests start removing the queen angelfish from the nearby reef to stock their home aquaria. If the hawksbill sea turtles and queen angelfish are removed, which organism is most likely to benefit?.
Answer:
Sponges, Anemones, Squid and Shrimp.
Explanation:
Those are the organisms that the sea turtle feed on.
Sponges, Anemones, Squid and Shrimp are most likely to benefit since the sea turtles and angelfish feed on them.
What happens if hawksbill sea turtles and queen angelfish are removed?Hawksbills contribute to the preservation of coral reef health. Reef fish have easier access to food because they clear sponges and other prey off the reef's surface. They are also valuable for tourism and have cultural significance.
Queen angelfish are omnivores that primarily eat algae and sponges. They are opportunistic and will consume jellyfish, soft corals, and sea fans. Young fish clean larger kinds of fish by removing parasites from their skin so that they can be eaten.
The populations of the organisms that Hawksbill Sea Turtles and queen angelfish consume, such as sponges and sea urchins, would probably explode if they became extinct. This would result in widespread erosion and possibly the collapse of marine ecosystems like coral reefs.
