Answer:
The food web provides a better model of an ecosystem because the food web is a model between MANY different consumers and producers in an ecosystem.
Explanation
While the food chain is a model for just one consumer and producer. energy moves up a food chain.
Oh it's called conjugation so that'll be 'C' option!
Recombination is the method by which organisms can randomly assort their genotypes amongst each other to create offspring with a different haplotype than either of its parents. This can be done by either copying sequences from one homologous chromosome to another (no physical exchange) or crossing over (physical exchange.
Crossing over is a mechanism in eukaryotes by which recombination can occur, in which the two homologous chromosomes contributed by both parents literally cross over and break at certain points to exchange certain sections of the chromosomes amongst each together.
Self fertilizing organisms typically do not produce offspring that are genetically identical. However, this has an inbreeding effect on its offspring, since it is recombining from the same genotype and so has a higher chance of producing homozygous offspring. This is very detrimental for mammals and some eukaryotes, but in some other organisms such as bacteria, homozygosity is typically not an issue.
Answer:
The question is somehow not correct, it suppose to be what is the MASS of an object that needs a force 4500N to accelerate it at a rate of 5 m/s as gotten from another website.
The correct answer is 900kg.
Explanation:
To get the mass of the object use the formula
F=Ma
Where F is force
M is mass
a is acceleration.
F= 4500, M=? a=5m/s
4500= M× 5
M=4500/5
M=900kg
Mass is in kg
Answer:
igneous
Explanation:
Igneous rock is the type of rock that contains a large amount of silica. Igneous rocks are formed when molten rock (magma or lava) cools and solidifies. Silica is a common component of magma, so igneous rocks are often rich in silica. Glass, which is also made from silica, is not a type of rock. Metamorphic and sedimentary rocks are formed through processes that do not involve the melting of rock, so they typically contain lower amounts of silica.
