3. The type of dominance is incomplete dominance.
in the water culture experiment why should a lack of nitrate cause reduced growth
Answer:
Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces. ... This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .

Answer:
Decomposers - Oranisms that decompose, or break down, dead or decaying organisms.
Tertiary Consumers - Organisms that obtain nutrients and energy by eating primary and secondary consumers. They are at the topmost level of the food chain.
Secondary Consumers - Organsims that prey on primary consumers for their food and energy.
Primary Consumers - Organisms that feed on primary producers, or plants for energy. They are herbivores, and make up the second trohpic level.
Producers - They are autotrophs, or organisms that produce their own food using light, or chemical energy. Plants are the main producers in many ecosystems. Others include algae, and bacteria.

If the us modifies techniques for timber management, it is expected that us forests will be able to meet long term timber needs
If the US modifies techniques for timber management?Forest management is the rational and environmentally appropriate use of forest resources. Management is an economic activity opposed to deforestation, as there is no total removal of the forest and even after use, the site will maintain its forest structure.
With this information, we can conclude that If the us modifies techniques for timber management, it is expected that us forests will be able to meet long term timber needs.

Large holes in the ground left over after mining operations are sometimes called what
Answer:
a pinge?
Explanation:
Large holes in the ground left over after the mining operations are sometimes known as the pinge. These are made up by the mining activities that are making the depression or the sink holes in it.
What kind of activity is pinge made up by ?It is the human activity in which the extractions are done in order to make the use of the resources . It is the artificial human activity.
This depression or sink-hole is usually caused out by collapse of the old underground mine works which are close to Earth's surface.Unlike any natural landforms , a Pinge is the direct result of the human activity. The collapses do make up big larger holes that almost makes the pinges in the process of mining.
Pinge is also formed by the surface in which the land is not supported properly and the extraction has made the holes in the lands because of the more pressure and the type of extracting machines that are being used in it.

B. Advantage: Hydrogen is easy to transport.
Disadvantage: Hydrogen emits pollution.
C. Advantage: Hydrogen is an efficient form of energy.
Disadvantage: Hydrogen is expensive.
D. Advantage: Hydrogen fuel has established infrastructure.
Disadvantage: Hydrogen is scarce.
Hydrogen is used as an energy source as it is an efficient form of energy compared to the other sources, but it is expensive. Thus, option C is correct.
What is hydrogen energy?
Hydrogen energy is the use of hydrogen gas in the production of energy that is more efficient than the other sources as it has a greater fuel conversion rate than petrol and diesel.
Ther hydrogen energy is also a disadvantage as it is expensive as it includes steam reforming and electrolysis which are costly processes and hence are not used globally.
Therefore, hydrogen energy is efficient but is an expensive method.

If a person who commits a crime leaves even the smallest speck of their blood, hair, or other organic matter, the DNA in this material can be amplified by PCR subjected to genetic analysis.
What is the use of PCR in crime scenes?
With PCR, crime scene investigators can extrade strains of DNA into quantities that may be recognized and connected to a suspect. Biologists can produce a couple of copies of character genes to look at gene function, evolution, and different topics.
PCR is a procedure wherein tens of thousands and thousands of copies of a particular collection of DNA may be made in a count number of just a few hours. This is crucial for forensic DNA samples because the DNA regularly located at crime scenes is constrained in each amount and quality.

The number of chromosomes in a human gamete is __________; this is referred to as a __________ chromosome number.
Answer:
23, haploid
Explanation:
there are 23 chomrosomes in both a egg and sperm cell
this makes them haploid as they have a single set of unpaired chromosomes
hope this helped
The number of chromosomes in a human gamete is 23, and this is referred to as a haploid chromosome number because in a diploid cell there are a total of 46 chromosomes.
What are the chromosomes?The chromosome numbers vary in the diploid cell of the human and in the haploid cell of the human, which is in the sperm and in the egg cell. The diploid cell has 46 chromosomes, and this cell can undergo either mitosis to produce an exact equal cell with 46 chromosomes or it can undergo the meiosis process to produce the 23 chromosomes. The mitosis is helpful for filing up the cut site, for cell duplication, or for body size growth, and the meiosis is helpful for gamete formation and helpful for the reproduction.
Hence, the number of chromosomes in a human gamete is 23, and this is referred to as a haploid chromosome number.

The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.
What is a random mutation?Random mutations are just that, they are changes in the genome of an organism that arise randomly. These mutations are the backbone of evolution and natural selection in that when they arise, if the organism becomes more adapted to survival as a result of this mutation, it increases its odds of survival through natural selection.

A particular viral genome can replicate in 8 hours. If you start with 55,000 copies of this genome, about how many copies would be present in a host's cell after 48 hours of growth
If a viral genome can replicate in 8 hours and the starting copies is 55,000, the number of copies after 48 hours would be 3,360,000 copies
Replication ratesThe starting number is 55,000 and replication happens every 8 hours.
Starting from 0 hours, the genome would 55,000
After 8 hours = 55,000 x 2 = 110,000 copies
After 16 hours = 110,000 2 = 220,000 copies
After 24 hours = 220,000 x 2 = 420,000 copies
After 32 hours = 420,000 x 2 = 840,000 copies
After 40 hours = 840,000 2 = 1,680,000 copies
