Answer: Exercise causes the heart to pump blood into the circulation more efficiently as a result of more forceful and efficient myocardial contractions, increased perfusion of tissues and organs with blood, and increased oxygen delivery. Aerobic exercise trains the heart to become more efficient.
Explanation:

Answer:
Pretty much the more activity you do, or the more intense it is, the faster your heartrate will be. Your heart needs blood, and when you're exercising the blood is pumping through your body faster.

No
Answer:
CTGACTGACC to GACUGACUGG
AGCTCCGATC to UCGAGGCUAG
GCTAATCGAT to CGAUUAGCUA
Explanation:
Transcription is the process whereby a DNA template is used to form a mRNA molecule in the nucleus following the complementary base pairing rule. The complementary base pairing rule as postulated by Chargaff states that an Adenine base will always pair with Thymine (Uracil in RNA) while Guanine base will always pair with Cytosine i.e A-U, G-C.
N.B: Thymine in the DNA will yield Adenine in the mRNA while Adenine in the DNA will yield Uracil in the mRNA.
Hence, according to this question, the following DNA templates will be transcribed as follows:
1. CTGACTGACC to GACUGACUGG
2. AGCTCCGATC to UCGAGGCUAG
3. GCTAATCGAT to CGAUUAGCUA
Question 1(Multiple Choice Worth 4 points) (01.03 LC) Organic molecules are sometimes found within meteorites that crash into Earth. Which meteorite condition in space is similar to what most likely was present in Earth's early atmosphere? Abundance of oxygen Very cold temperatures Presence of inorganic molecules Low levels of ultraviolet radiation
Answer:
Presence of inorganic molecules
Explanation:
Earth's primitive atmosphere contained a mix of different inorganic compounds (gases) including, among others, water vapor (H2O), carbon dioxide (CO2), ammonia (NH3), methane (CH4), etc. It has been proposed that these inorganic molecules would generate the conditions needed to form a "primordial soup" of organic molecules (i.e., RNA nucleotides, amino acids, etc). Subsequently, this soup would accumulate in water bodies of the primitive Earth due to endogenous abiotic syntheses and the delivery caused by comet/meteorite collisions.
Answer:
C. Presence of inorganic molecules
Explanation: i took the test and got it correct :)
46. A sample of human DNA is made up of approximately 30% adenine. Based on
this information, and the base pairing rules, approximately how much cytosine
found in human DNA?
A 70%
B 20%
C 30%
D 10%
Help please
Answer:
its A/F
Explanation:
A sample of human DNA is made up of approximately 30% adenine. The quantity of cytosine found in human DNA will be 20%. The correct option is B.
What is DNA base pairing?DNA base pairing is the pairing or joining of DNA bases to each other with hydrogen bonds. There are four types of bases present in DNA. They are adenine, thymine, cytosine, and guanine.
Adenine pairs with thymine with double hydrogen bonds and cytosine joined with guanine with triple bonds of hydrogen. The pairing between these base pairs is alternated in the sequence of DNA.
According to the base pairing rule. There will be 100% of these bases present together. So if there is 30% adenine, there will be 30% thymine. The total becomes 60%. Now remain is 40%. So there will be 20 % cytosine and 20% guanine.
Thus, the correct option is B 20%.

7. Which molecule is light energy temporarily stored in before being used to make glucose?
Answer:
The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose. Photosynthesis is a two stage process. As is depicted here, the energy from sunlight is needed to start photosynthesis. The initial stage is called the light reactions as they occur only in the presence of light

Which of the following is an example of specific immunity?
Answer:
Immunity to Small Pox
Explanation:
Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.

Suggest what might happen if cells grow and reproduce in an environment where no cholesterol is available.
Cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis
Explanation:
If cells grow and reproduce in an environment where no cholesterol is available than cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis.
What is plasma membrane?Cell membrane has been defined as a wall that differentiate and protect the inner structure of the cell from the outer environment. The main function of the cell membrane has to keep away the toxic material out of the cell. The cell membrane contain the channels as well as receptors that gives permission to only selective permeable membrane to enter into the cell.
Cells must maintain homeostasis to survive. To do this cells use various processes. One process keeps the right amount of water inside the cell. A cell takes in the same amount of water as it looses describe that it is maintaining homeostasis by keeping it's water concentration level.
Therefore, If cells grow and reproduce in an environment where no cholesterol is available than cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis.

What type of organisms are most likely to be found as fossils?
Organisms with hard body parts such as a mineralized shell are much more likely to become fossilized as har parts are not fed by scavengers.
Types of organisms that are most likely to be found in the fossils have completely made up of hard bodies or at least some hard body parts.
The deposit of sediments and the finer the sediment deposited the likelier fossilization is to occurThe hard parts of organisms, for instance, bones, and teeth have had becoming fossils.Scavengers normally leave such hard parts, however, they also decay with time but this gives more time to be buried in sediments.These hards parts have better chances than the organisms with soft body parts to be found in fossils.

1. How would you describe the biosphere?
2. What are some ways we, as humans, affect the biosphere?
Answer:
1. The Biosphere is a life-supporting stratum of Earth's surface, extending from a few Km into the atmosphere all the way to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients
2. Humans burning fossil fuels and growing animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. Humans have caused threats to non-renewable resources, CO2 production& global warming, as well as over-competition for food between native and introduced species.
