Answer:
During exercise, your heart typically beats faster so that more blood gets out to your body. Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps.
Explanation:
During workout, the heart usually beats faster, allowing more blood to leave person's body. The heart can also boost stroke volume by pumping harder or increasing the amount of blood in the left ventricle before it pumps.
What is workout?A session of vigorous physical exercise or training at either gym, home, or any fitness center is referred to as workout.
The heart usually beats faster during exercise, allowing more blood to leave the body.
The heart can also increase by pumping the stroke volume more forcefully or increasing the amount of blood in the left ventricle prior to pumping.
Thus, heart rate change during and after an exercise is performed for two different periods of time.

30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample 30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample
Answer:
See explanation
Explanation:
Nitrifying bacteria convert the most reduced form of soil nitrogen, ammonia, into its most oxidized form, nitrate(Science direct).
Nitrifying bacteria converts ammonia to nitites and finally to nitrates in the soil.
Hence, when 30 g of ammonia, nitrate and nitrite are added to a soil sample in the presence of nitrifying bacteria; the concentration of ammonia decreases over time while the concentration of nitrite and nitrate increases over time.
ammonia stays the same
nitrates decrease
nitrates increase

Cross two pink snapdragons. What is the genotypic and phenotypic probability of such a cross?
Answer:
Genotypic probability = 1RR: 2Rr: 1rr
Phenotypic probability = 1Red: 2Pink: 1white
Explanation:
This question involves a single gene coding for skin color in snapdragon plants. The alleles are incompletely dominant over one another and hence, produce an intermediate pink phenotype.
According to this question, two pink/heterozygous snapdragons were crossed i.e. Rr × Rr. Each parent will have gametes R and r. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Genotypic probability = 1RR: 2Rr: 1rr
Phenotypic probability = 1Red: 2Pink: 1white

Would a volcanic eruption affect Earth’s climate?Justify your response.
Answer:
Explanation:
The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.
How important are proteins to the function of a cell?
Question #1
Which statement about meiosis is true
Answer:
A.
Explanation:
The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

Which of the following are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes? (Choose all that apply)
•comparison of human behaviors
•carbon dating of fossils
•comparison of blood proteins
•comparison of homologous structures
Answer:
B and D
Explanation:
Human behaviors do not affect the entire evolution of every lifeform that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a lifeform could be, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose fast, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
For D, I kinda forgot most of my explanation, but I remember that it's correct, as I got the question correct on the assignment.
The carbon dating of fossils and comparison of homologous structures are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes.
So, option B and D are correct one.
Human behaviors do not affect the entire evolution of life of organism that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a life of any organism, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose faster, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
By comparing of homologous structures we determine nucleotide sequence exchanged between two similar or identical molecule of DNA. So, option D is correct
What is Carbon dating?It is also referred as radiocarbon dating.It is the method used to determine the age of the living organism containing organic( carbon ) based material by using isotopes of carbon which is radioactive.Learn about carbon dating

7. Why is it so unlikely for a girl to get a disorder like Duchenne Muscular Dystrophy
Answer:
Because it takes a very long time and an interesting mindset.
Explanation:
People don't really have an explanation for the things that we do they just suddenly build up inside us
Answer:
This is because the mutated gene responsible for Duchenne is located in the X chromosome. Girls have two X chromosomes, meaning that the body usually inactivates the chromosome that carries the mutation. The female will carry the mutation, but manifest little to no symptoms of the disease.

what happens to waste material in surface mining?
Answer:
Your answer is that mining activities increase the volume and rate of exposure of sulfur-containing rocks to air and water, creating sulfuric acid and dissolved iron.

Help biyology teacher
Answer:
C. P -› F1 -› F2
Explanation:
In genetics and breeding, the following symbols represents the following:
P => parental
F1 => First filial generation
F2 => Second Filial generation
The crossing of two parent plants (P) produces offspring that is tagged the first filial generation (F1). The next cross involving the F1 offspring produced second filial generation (F2).
Therefore, the correct sequence is:
P -› F1 -› F2

Explanation:

Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.
What is oesophagus?
The digestive system, sometimes known as the gastro-intestinal tract, includes the oesophagus (gullet) (GI tract). An oesophageal tube is made of muscles. It joins the mouth with the stomach.
The oesophageal walls contract together as you swallow food (contract). This causes the food to travel from the mouth to the stomach.
The diaphragm is a layer of muscle located below your lungs. It facilitates breathing. The majority of your oesophagus is located in your chest above the diaphragm.
Therefore, Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.
