Why do you think hemoglobin levels vary with altitude?
Answer:
haemoglobin in blood increases at high altitude. This is one of the best-known features of acclimatisation (acclimation) to high altitude. Increasing the amount of haemoglobin in the blood increases the amount of oxygen that can be carried.
This type of energy is not always predictable.
Answer:
Wind energy.
Explanation:
In this way, the biggest shortcoming of wind energy, which is that it is not always stable and predictable, is solved by the new technology. It goes without saying that this impressive and innovative combination of wind as a renewable energy source and the power of water as storage energy has a lot to offer in the energy production field.
PLEASE HELP!!!!! Describe in detail the process of dna replication
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Deoxyribonucleic acid and ribonucleic acid (DNA and RNA, respectively) are very important
biomolecules necessary for life. In at least 7 sentences and in your own words, compare
and contrast DNA and RNA. Explain what you know about the components (parts) of DNA
and RNA and their importance. Be sure to include at least five of the following words:
.
• Nucleic acid
• Nucleotide
• Nitrogen base
• Gene
• Genetic code
• Phosphate
• Sugar
• Protein
• Double helix
• Backbone
Answer:
pa heart follow back follow me brainliest me please
Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

Shelly is in Hawaii on vacation with her family. What type of rock would she most likely find on the surface of Hawaii?
Answer:
igneous rocks
Explanation:
since Hawaii is so densely populated with volcanoes, the probability of finding rocks due to volcanic eruptions would be very likely compared to sedimentary or metamorphic.

which laboratory tools are useful when looking at internal organs of an earthworm
Answer:
An earthworm's internal organs can be viewed through a dissecting microscope. This type of microscope allows enhanced observation of objects that are too large for a compound microscope. Because the magnification is low, this microscope cannot be used to examine cells.
How is local weather influenced by global patterns of atmospheric movement?
Answer: A mountain range in the path of prevailing winds can influence where precipitation falls. When humid winds blow from the ocean toward coastal mountains, they are forced to rise. The rising air cools and its water vapor condenses, forming clouds.

(Fossils provide scientists with evidence that allows them to hypothesize how living organisms have evolved over time. Tiktaalik roseae was a unique organism that has been nicknamed the “fishapod” because it is believed to be a species had traits of both fish and tetrapods, the first four-legged animals.)
Which evidence would scientist use to make the connection between ancestry of fish and tetrapods using Tiktaalik roseae?
-using transitional forms
-using relative dating
-studying decreasing complexity
-studying analogous structures
Answer:
A. using transitional forms
Explanation:
On Edge 2020
Using transitional forms is the evidence scientist use to make the connection between ancestry of fish and tetrapods using Tiktaalik roseae.
What is Transitional forms?This is referred as the remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group.
The transitional form which is option A is mostly suited as the organisms involved have common traits.

What does this pyramid tell us about the population?
The answer is A. The population is growing.
The pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.
What is population?Population is defined as the quantity or population of people living somewhere who are a particular social, cultural, economical, ethnic, or racial category. Making decisions can be aided by knowledge of how population parameters, such as size, regional distribution, age structure, or birth and death rates, vary over time.
The pyramid is used to show the growth in population of a country or population of the city. In the pyramid the growth of population is equal in both male and female population. The pyramid shows that the population of older generation is less than the population of younger generation peoples.
Thus, the pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.

how can genetically modified bacteria with human genes be used to treat human diseases
In the 1980s, scientists discovered how to produce human insulin by transplanting the genetic information for the human insulin hormone from a human cell, into the DNA of the E. coli bacterium. This reprograms the bacteria to produce insulin, in just the same way as they make their own proteins.

how can use of fertilizers affect respiratory health?
a) they directly produce gas particles of air pollution
b) they can contaminate bodies of water
c) they can contain contaminants that can enter the air during storms or high winds
d) fertilizer use does not impact respiratory health
Answer: C) They can contain contaminants that can enter the air during storms or high winds.
Explanation: A is wrong because I got it wrong (Sorry, can't give much explanation there).
B is wrong because water contamination does not directly relate to respiratory health.
D is wrong because fertilizers can impact respiratory health (Explanation seems lack-luster, but I feel like this is common sense).
Hope this helps :)

how far does a car travel in 0.75 h if it's moving at a constant speed of 88 km/h
Answer:
Distance = 66 kilometers
Explanation:
Given the following data;
Time = 0.75 hour
Speed = 88 km/h
To find the distance traveled by the car;
Distance = speed * time
Substituting into the equation, we have;
Distance = 88 * 0.75
Distance = 66 kilometers.
Therefore, the car will travel a distance of 88 kilometers.
