What is the per capita growth rate of a population of 250, with 50 births and 80 deaths in a year?
A.
1.2
B.
0.12
C.
-1.2
D.
-0.12
Answer:
D.
Explanation:
The first two options, A and B, can be eliminated because we know that the growth rate must be negative — more people are dying than are being born!
The term "per capita" means per person. Which answer makes more sense, losing 1.2 people per person or 0.12 people per person? While both might be a little confusing, you can't lose more than one person per person! Therefore, the answer is D.
Jackson, a 4-year-old boy, is unable to get the measles (MMR) vaccine due to a severe allergy to the antibiotic neomycin. Jackson will be starting kindergarten next year and his parents are trying to decide whether to send him to Oak Crest Elementary School, which has an 80% vaccination rate for MMR, or Lincoln Elementary School, which has a 95% vaccination rate for MMR.
Required:
a. What would you advise them and why?
b. Is Jackson at risk of contracting measles? Explain your reasoning.
Answer:
In Lincoln Elementary School.
Explanation:
I advise them to send Jackson to Lincoln Elementary School which has 95% vaccination rate for MMR because there is less chances of having measles to Jackson as compared to Oak Crest Elementary School having 80% vaccination rate for MMR. Yes, Jackson is at risk of contracting measles because of no immunity acquire against measles disease by its body. The vaccine can provides immunity to Jackson from the disease but he can't take it due to allergy.
Where is the diaphragm located in relation to the lungs?
a) inferior
b) medial
c) superior
{ Relating to a crash course video called: Respiratory System Crash Course}
[any information would be very much appreciated! thank you :D]
Answer:
A. Inferior
Explanation:
If you're not familiar with anatomical terms, a quick summarization would be:
-Inferior: below
-Superior: above
-Medial: towards the midline of the body
Upon googling a picture for the diaphragm and lungs, you will see that the diaphragm is a muscle situated directly below the lungs. The phrase "located in relation to" is asking you specifically "when compared to". Therefore, since the diaphragm is located below the lungs, the answer would be inferior.
I hope this answer and explanation helped you understand this topic a little bit more!
The diaphragm is located in inferior to lungs.
What is diaphragm ?
In mammals, the diaphragm is a dome-shaped, muscular and membrane tissue that divides the thoracic and abdominal compartments.
It is the primary respiratory muscle.
The diaphragm gets contract and flatten up during we inhale, while the chest cavity expands.
Vacuum is created due to contraction, which pulls air into the lungs.
Exhalation relaxes the diaphragm and causes it to return to its domelike shape, pushing air out of the lungs.
So we can conclude that the diaphragm is the muscle that connects the chest cavity to the abdomen and it is the primary respiratory muscle, when one breathes in, the diaphragm muscle contracts, causing the lungs to expand and vice versa, and most importantly it located inferior to lungs.

In the trp operon, tryptophan serves as a(n) ___________________, binding to the repressor and causing it to block to attachment of RNA polymerase.
a. operator
b. inducer
c. repressor
d. corepressor
e. gene
In the trp operon, tryptophan acts as a corepressor, binding to the repressor and inducing it to stop to attachment of RNA polymerase. Therefore, option D is correct.
What is trp operon?The trp operon is a group of genes in bacteria that are involved in the biosynthesis of the amino acid tryptophan. The operon is composed of five structural genes, trpE, trpD, trpC, trpB, and trpA. These genes code for the enzymes involved in tryptophan biosynthesis.
In the trp operon, the presence of tryptophan serves as a corepressor. The tryptophan molecule binds to the trp repressor protein, causing a conformational change that allows it to bind to the operator region of the operon.
This blocks the attachment of RNA polymerase to the promoter, preventing transcription of the genes involved in tryptophan biosynthesis. Thus, option D is correct.

If a motion is not seconded, what happens to the motion?
Answer:
After a motion is proposed, if the motion requires a second and none is immediately offered, the chair of the body will usually ask, "Is there a second?" If no second is obtained within a few moments of proposing the motion, then the motion is not considered by the assembly, and is treated as though it was never offered. Such a motion may be introduced again at any later time.

2. Plants follow a reproduction pattern called alternate generations. Explain the two processes in alternate generations.
Answer:
Alternation of generations is a type of life cycle by which species alternate haploid (n) and diploid (2n) individuals.
Explanation:
Alternation of generations refers to the life cycle observed in terrestrial plants by which species alternate between haploid (i.e., organisms having a single set of chromosomes) and diploid (2n, i.e., organisms having a single set of chromosomes) generations. Plants alternate between a sporophytic stage and a haploid gametophytic stage. This alternation of generations is accompanied by the alternation between sexual reproduction, where the fusion of male and female gametes from the gametophyte generation produces a diploid zygote that develops into the sporophyte, and asexual reproduction, where spores (generated in the sporangium of the diploid sporophyte) are released and germinate into new individuals.

How many cells do you end up with in Meiosis?
A) 2
B) 1
C) 3
D) 4
Answer:
During meiosis , four daugther cells are produced
Answer:
4 cells. You end up with four cells.
Explanation:
Each daughter cell undergoes meiosis-II, producing two cells. In meiosis-II the separation of two chromatids occur so that equal number of chromatids (in fact chromosome due to duplication of genetic material) goes to each of the daughter cell.
Thus, at the end of meiosis-II, four daughter cells are formed. Each cell has half the number of chromosomes present in the diploid cell.

Answer:
sea urchin
Explanation:
An echinoderm is an invertebrate animal (without backbones) that belongs to the Echinodermata group. Members of the echinoderm group are characterized by their possession of a star-shaped and spiny-skinned morphology. They are found strictly in marine habitats. They include sea urchins, sea cucumbers etc.
According to this question involving an echinoderm that is covered with movable spines and that eats seaweed, this describes a SEA URCHIN. This is due to the possession of the MOVABLE SPINES by sea urchins. Sea urchins, like other echinoderms, are predatory and feed on seaweed (algae) as well.

O All vertebrates inherit the same sequence of DNA from their parents.
O All vertebrates live in similar environments which require the same adaptations
A) All vertebrates develop a backbone that protects the spinal cord.
Vertebrate embryos all follow a very similar development process because all vertebrates inherit the same sequence of DNA from their parents.
Why vertebrate embryos follow similar development process?Early developmental sequences of all vertebrates are similar due to common ancestry.
All vertebrate embryos, have gill slits and tails and by the adulthood, they lose the tail.
From the study of ontogeny, one can discover about transformation of species through evolutionary change.
Here, ontogeny is the process of individual development from a single cell to adulthood of the organism.
