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.

Vertebrate embryos all follow a very similar developmental process. Which statement could explain this similarity? (1 point)
O All vertebrates develop a backbone that protects the spinal cord.
O All vertebrates require the same nutrients during embryological development
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.

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.

An echinoderm that is covered with movable spines and that eats seaweed
sea urchin
sea star
brittle star
sea cucumber
echinoderm
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.

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.

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.
Which statement applies to all forms of sexual reproduction?
Choose 1 answer:
A All offspring from a mating look identical to the parents.
B
All offspring are clones.
C
Offspring receive genetic material from two gametes.

If an organism is well adapted to its environment and a rapid major change occurs to the environment as a result the organism will adapt, and the species will evolve to fit its new environment. Organism produce certain adaptation in order to survive in the new environment conditions.
Birds have different lengths and shapes of beaks because of different size of food are present on which they feed. Some foods are big size so the beak size is big whereas some have small beak size due to small food size.
Use of electric vehicles, reduce the use of biofuels and promoting more sustainable uses of land and growing more forest are the some ways that mitigate climate change.
There are four potential outcomes for a species when that maximum limit is reached i.e. the organism will not be able to adapt, and the species will go extinct. The second possibility is that organism will not be able to adapt and the species will evolve into a new species.
The third possibility is that organism will adapt, and the species will evolve into a new species. The fourth possibility is that organism will adapt, and the species will evolve to fit its new environment.

25. A cell has 20 amino acids. How many molecules of tRNA are in the cell?
1. Four
2. Three
3. More than 20
4. At least twenty
5. Fifteen
6. I do not know.
Answer:
I think no 3 will be the answer.
In cell one amino acid can bind with two or three different tRNA during protein synthesis in the translation process, hence 3 option is correct more than 20 molecules are found.
What is tRNA?Because they can read nucleic acid words (like mRNA codons) and transmit the relevant messages, tRNA molecules serve as translators of amino acids. for each of the 20 amino acids.
There is a tRNA some amino acids bind to 2 or 3 different tRNAs, so cells may contain as many as 32 different tRNAs. Possibility of more than one tRNA and more than one anticodon for an amino acid, there is often only one aminoacyl tRNA synthetase for each amino acid.
Enzymes known as transfer RNA (tRNA) synthetases are responsible for joining a particular amino acid to its associated tRNA in order to produce proteins at the ribosome.
Therefore one amino acid can bind with two different tRNA in a cell during translation, hence option 3 is correct.
