b. The activation of a G-protein receptor that leads to the secretion of a protein that makes you run.
c. The binding of epinephrine to a G-protein coupled receptor with the subsequent activation of a nuclear receptor.
d. The initiation of a signaling mechanism that leads to breakdown of glycogen into glucose that can then serve as the fuel for ATP production.
e. All of the above

Answers

Answer 1

Answer:

The correct answer is - D. The initiation of a signaling mechanism that leads to the breakdown of glycogen into glucose that can then serve as the fuel for ATP production.

Explanation:

In challenging or dangerous conditions, the body releases a hormone called Epinephering which is a fight or flight hormone that provides a high amount of energy for the particular action.

Epinephrine hormone binds to beta-adrenergic receptors present on muscles and responsible for the rapid conversion of glycogen to glucose-1-phosphate. The glucose results in condition to rapid synthesis of ATP in muscles and thus helps in muscle actions.

What is a nitrogen?

Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.

Nitrogen is important to the chemical industry. It is used to make fertilizers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process.

Nitrogen is important to all living things, including us. It plays a key role in plant growth: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants [1]. Nitrogen is necessary for our food supply, but excess nitrogen can harm the environment.

Did the seized tusk come from one of the recently slaughtered elephants? ________ What evidence supports your finding?

Answers

Complete question:

Now you are ready for your first major assignment. Your colleagues are investigating a newly seized tusk and wonder if the tusk is from a recently discovered crime where 10 elephants from the same population were found dead with their tusks removed. The genotype of the seized tusk for five short tandem repeat (STR) loci is shown in Table 1. Allele names for each of the STR loci correspond to their size in base pairs (bp). Table 2 lists the genotypes of the same five STR loci for 10 recently slaughtered elephants.

Did the seized tusk come from one of the recently slaughtered elephants? ________ What evidence supports your finding?

Note: You will find the tables in the attached files

Answer:  

Probably the seized tusk belonged to elephant number eight.

Explanation:

Potentially, the seized tusk might belong to individual number eight. In both the tusk and the elephant, the genetic analysis resulted in the same-sized alleles for each locus.

FH19: 193 193FH60: 147 147FH67:97 103FH71: 62 62FH129: 152 160

The fact that, among the ten individuals of the population, only the individual number 8 matches the tusk for SRT loci, suggests that it belongs to the animal, but it does not ensure it 100%.

Answers

Answer:

D. Population genetics

Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. ... In natural populations, however, the genetic composition of a population's gene pool may change over time.

Explanation:

microevolution - evolutionary change within a species or small group of organisms, especially over a short period. (Not studying the overall evolution in the population, just a single allele usually) Not it then

macroevolution - Macroevolution in the modern sense is evolution that is guided by selection among interspecific variation, as opposed to selection among intraspecific variation in microevolution (this goes over huge groups of different species) Not it then

gene pool - The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. (Not the study of evolution in a population) Not that then

what three phases of the cell cycle are considered interphase

Answers

Answer:

The cell cycle has three phases that must occur before mitosis, or cell division, happens. These three phases are collectively known as interphase. They are G1, S, and G2. The G stands for gap and the S stands for synthesis.

Explanation:

The three phases of the cell cycle that are considered interphase include G1, S phase and G2.

The cell cycle can be divided into the interphase and mitotic (M) phases.

The interphase can in turn be divided into a Growth G1 phase, synthesis (S) phase and Growth G2 phase.

The synthesis of the genetic material (DNA) occurs in the S phase, whereas in G1 and G2 the cell synthesizes all materials required to enter into cell division.

In conclusion, the three phases of the cell cycle that are considered interphase include G1, S phase and G2.
