Primary consumers are the ones eating the plants, so mostly they are herbivores, compared to the secondary consumers, which eat both, that can be called omnivores
Answer:
Charles Ehler: incorrect.
Wendell Mullison: correct.
Robert Rodriguez: correct.
Judy Johnson:correct.
Explanation:
-Charles Ehler´s statement is incorrect because in order for a chemical company launch a new product it must pass several tests, that´s why products lasts years in proves, there are several tests such as the environment test that proves that the product doesn´t affect other species, or the human safety that makes sure the product doesn´t affect human health.Wendell Mulison´s statement proves to be correct with this as well.
-Robert Rodriguez´s statement is correct because even though there are several tests that take care human healt there are just a few based on the damage pesticides produce to the land where are used.
-Judy Johnson´s statement is correct because science has proved that the resistant of parasites as being increasing with the products tat are used to combat them. Bacterias are an example of it, many drugs used against bacterias are now useless for some people because of the resistantthey have developed.
-One specie that can be taken as a pesticide can be the ground snail, that affects some plants and also may contain a parasite aclled "Hepatic fasciola" that affects sheeps and goats of farmers.
-One viable method to control pesticides is the sue of other species to control them, this specie has to be adequate to the land, for example, if a farmer wants to get rid of the ground snails because of the parasite and the damage they do to their platings, they can introduce ducks to the farm that eat them without damaging the land with any kind of chemical product.
Answer:
Genotype ratio: 1 (RR) : 2 (RW) : 1 (WW)
Phenotype ratio: 1 Red : 2 Roan : 1 White
Explanation:
Codominance is a kind of inheritance pattern in which both alleles are equally dominant in a gene. This means that both alleles when in a heterozygous state will be simultaneously expressed. According to this question, allele for a red coat (R) and the allele for a white coat (W) results in offspring with a roan coat (RW) in cattle.
Hence, in a cross between a a roan cow (RW) and a roan bull (RW), the following gametes will be produced: R and W.
Using these gametes in a punnet square (see attached image), the offsprings with the following genotypes will be produced: RR, RW, RW, WW.
Therefore, based on the results of the cross;
Genotype ratio: 1 (RR) : 2 (RW) : 1 (WW)
Phenotype ratio: 1 Red : 2 Roan : 1 White
I think it is liqid but i dont know realy.
