How are the smallest ocean waves produced?
Answer:
Ocean waves are usually formed by a distant wind. ... The area which the wind affects the surface is called the fetch. The larger the fetch, the greater the waves produced. the small waves generated by storm winds are often confused and disorganized.
Explanation:
Answer:
For a wave to effectively be produced there need to be large wind, long period of time and a large distance of water. If they are all reduced, then there would be a reduction in the intensity of the wave.

1) All of the following are examples of an asexual reproduction except
a) Cloning technique b) Forming zygots
c) Runners technique I
d) Tuber technique in the potato
Answer:
b) Forming zygots
Explanation:
A zygote can be defined as a eukaryotic cell formed by the fusion of gametes during sexual reproduction. In general, a zygote is a diploid (2n) cell produced by the fusion of two haploid (n) gametic cells (eg., in mammals, sperm and egg cells). In multicellular organisms, the zygote is the first stage of development, which will give rise to an adult organism as it divides and grows. A zygote cell can be considered as a pluripotent stem cell because it differentiates into all cell types.

The average molecular weight of proteins encoded in the human genome is about 50,000. A few proteins are very much larger than this average. For example, the protein called titin, which is made by muscle cells, has a molecular weight of 3,000,000. Estimate how long it will take a muscle cell to translate an mRNA coding for an average protein and one coding for titin. The average molecular mass of amino acids is about 110 daltons. Assume that the translation rate is two amino acids per second.
Answer:
13,636 seconds = 227.3 minutes = 3.79 hours
Explanation:
The titin protein has a molecular weight of 3,000,000 daltons, while the average molecular mass of one amino acid is 110 daltons, so it is expected that this protein is composed of 27,273 amino acids (3,000,000 daltons/110 daltons = 27,272.72). Moreover, and since the translation rate is two amino acids per sec, it is expected that the protein will be synthesized in approximately 3.79 hours (27,272.72/2 = 13,636 seconds = 227.3 minutes = 3.79 hours).

An inflated basketball hold 6 liters of air at 3 ATM. How much air at 1 ATM went into the ball
Answer:
18 litres
Explanation:
Using Boyle's law equation as follows:
P1V1 = P2V2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (litres)
V2 = final volume (litres)
According to the information in this question, An inflated basketball hold 6 liters (V1) of air at 3 atm (P1). The volume of air (V2) at 1 atm (P2) that went into the ball can be calculated thus:
Using P1V1 = P2V2
3 × 6 = 1 × V2
18 = V2
V2 = 18 litres.
What would happen to Earth's climate if we had no moon, and why?
Answer:
The tilt creates what we know as seasons and changing weather. Without the pull of the moon, this tilt would change.
Explanation:
Either the tilt would become extreme, leading to extreme and severe seasons, or the tilt would decrease, and we would see almost no seasons at all. The moon influences life as we know it on Earth.
Answer: Because It is the pull of the Moon's gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth's tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).
The tilt creates what we know as seasons and changing weather. Without the pull of the moon, this tilt would change. Either the tilt would become extreme, leading to extreme and severe seasons, or the tilt would decrease, and we would see almost no seasons at all. The moon influences life as we know it on Earth.

In one of these systems, the prey are very large animals and the predators are verysmall animals, such as elephants and mosquitoes. Thus it takes many predators toeat one prey, but each prey eaten is a tremendous benefit for the predator population.The other system has very large predators and very small prey. Determine whichsystem is which and provide a justification for your answer.
Answer:
Due to its size and feeding requirement.
Explanation:
In the forest ecosystem, many lions feeds on one deer or buffalo because the food is in large amount and this food is enough to fulfill the requirements of that lions so we can say that many predators eats one prey while on the other hand, there are some predators that feeds on many prey at one because they are small in size and one prey did not fulfill their requirement so that's why the predator feeds on many preys. Fox feeds on many mice is the example of one predators feed on many prey.
which of the following does not affect the rate of photosynthesis a) temperature b) light intensity c) soil d ) water intake
Answer:
a) temperature
Explanation:
took test and got right
light intensity does not affect the rate of photosynthesis .
what is photosynthesis ?The process in which plants, algae and certain bacteria use light energy of sunlight, water, carbon dioxide and convert light them into chemical energy and starch. called as photosynthesis.
Photosynthesis occur in special organelles named chloroplast which has its own DNA, genes and hence can synthesize their own proteins.
Chloroplasts have stroma, fluid, and stack of thylakoids known as grana, three types of chlorophyll such as chlorophyll a, chlorophyll b, and carotenoids.
Oxygenic photosynthesis is commonly observed in plants, algae and cyanobacteria where electrons are transferred from water to carbon dioxide by using light energy, to produce energy, oxygen is produced along with carbohydrates.

Cystic fibrosis is a recessive genetic disease caused by a mutation in the gene that encodes the CFTR protein, which transports chloride ions in and out of cells. Some populations have a relatively high rate of cystic fibrosis carriers, possibly because the mutation protects against severe dehydration in diseases like cholera or typhoid. What concept does this best illustrate?
A: Polygenic traits
B: Genetic drift
C: Pleiotrophy
D: Heterozygote advantage
its letter b the genetic drift because it is mechanism of evolution in which allele frequencies of a population change over generation due to chance.
Cystic fibrosis is a recessive genetic disease that encodes the CFTR protein, but some populations have a relatively high rate of cystic fibrosis carriers, which protects against severe dehydration and is an example of the heterozygote advantage that is present in Option D.
What is the heterozygote advantage?When the gene is present in a heterozygote state, the gene product benefits the individual rather than harming him or her, as in sickle cell anemia and cystic fibrosis. In sickle cell anemia, the heterozygote state protects the person from malaria, and in cystic fibrosis, it protects the person from dehydration.
Hence, Cystic fibrosis is a recessive genetic disease that encodes the CFTR protein, but some populations have a relatively high rate of cystic fibrosis carriers, which protects against severe dehydration and is an example of the heterozygote advantage that is present in Option D..

how many chromosomes are there in human ovum
Answer:
23 chromosomes
Unlike all the other cells in a human body which are diploid, human sex cells are haploid. That means that both sperm cells and ova are haploid; containing only 23 chromosomes.
Explanation:
have a good day!
(─‿─)
The chromosomes in egg and sperm cells have just 23 chromosomes each.
What is gamete?Male gametes are termed sperm, while female gametes are called "ova." Gametes are an organism's reproductive cells, also referred to as "gender cells." Since gametes are haploid cells, each chromosome is present in one copy per cell.
Unfertilized reproductive cells are called gametes. A zygote is an egg that has been fertilized. Gametes are always haploid cells since they are a byproduct of meiosis.
Zygote is a diploid structure because it results from the fusing of a male and female haploid gamete.
Similar to a sperm, an egg has 23 chromosomes total, which is half the number found in a normal cell.
The resultant embryo will therefore have the typical 46 chromosomes in total after an egg and sperm join during fertilization.
Thus, there are 23 chromosomes in human ovum.

5. How does low biodiversity impact the stability of a tundra ecosystem?
4. Who else benefits from polar bear hunting?
3. Describe a polar bears niche.
1. How do tundra ecosystems in biodiversity compare in biodiversity to other types of ecosystems?
Answer: 5. Biologically numerous groups also are much more likely to include species that confer resilience to that ecosystem due to the fact as a network accumulates species, there may be a better risk of anybody of them having developments that permit them to conform to a converting environment.
3. The polar bear's ecological niche is that of a specialized predator of seals. When there are numerous seals around, adult polar bears will usually devour the blubber (fat) and pores and skin of the seals, which gives an awesome supply of energy. Younger bears will devour beef because the protein allows them to grow.

1. How do tundra ecosystems in biodiversity compare in biodiversity to other types of ecosystems?
Answer: Ecosystems in the arctic tundra are an example of those where there are fewer species overall than in other kinds of ecosystems.
2. What is a niche?
Answer: a role that a species plays in the ecosystem
3. Describe a polar bear's niche.
Answer: Some animals gain from polar bears' hunting of seals. A polar bear will leave behind significant portions of a seal after eating all of it. In tundra environments, these leftovers are a source of food for Arctic foxes, gulls, and other birds, particularly during the chilly winter months when there is nothing to eat. Healthy polar bear populations can have a good effect on other species' numbers, such as those of birds or Arctic foxes. Numerous other species are harmed when polar bear populations drop.
4. Who else benefits from polar bear hunting?
Answer: Arctic foxes, gulls, and other birds
5. How does low biodiversity impact the stability of a tundra ecosystem?
Answer: The species that provide resilience to an ecosystem are therefore far more likely to be found in biologically diverse groups because as a network accumulates species, there may be a greater chance that any one of them will have evolved to adapt to a changing environment.
