Answer:

In a collision, there is a force on both objects that causes an acceleration of both objects; the forces are equal in magnitude and opposite in direction. For collisions between equal-mass objects, each object experiences the same acceleration.

A marine ecologist counts the number of octopus in three different intertidal regions that are each two hectares. The octopus co
patriot [66]

Answer:

The best estimate of population density of this particular Octopus spieces is (TOTAL POPULATION OF THE OCTOPUS)/(TOTAL AREA OF LAND)

Population density = (15/6) Octopus per hectare

Explanation:

To estimate the population density of a spiece in a particular area of land, we count the total number of the specie in the area and divide the total number by the area of the sampling region.

Above, the marine ecologist counts the number of octopus in three different intertidal regions that are each two hectares. The octopus counts are 7, 2, and 6 respectively.

Therefore, the total number of Octopus is 7 + 2 + 6 making 15. The regions are 2 hectares each. Since there are three of the intertidal regions, the total area is 2 x 3(6 hectares).

Therefore, Population density = (15/6) Octopus per hectare

ra1l [238]

Answer:

B. WW or Ww

Explanation:

If the w allele is recessive, that means that the presence of any W alleles will mask the expression of the w allele. So the possible genotypes for no spots and hence solid coat, keeping in mind that there must be two alleles, one from each parent, are WW or Ww.

WW or Ww would both produce phenotypically solid coats. ww would produce a spotted coat.

Quién propuso el primer mecanismo de herencia a partir de la observación y la experimentación con plantas?
marusya05 [52]

Answer:

Gregor Mendel

Explanation:

Gregor Mendel fue un naturalista, biogista y matemático que demostró por primera vez los principios de la herencia utilizando su trabajo sobre las plantas de guisantes.

Publicó su trabajo en "Experiments in Plant Hybridization" en el año 1866. Al controlar la polinización, Mendel pudo cruzar plantas de guisantes con diferentes formas de rasgos. En el primer conjunto de experimentos de Mendel, experimentó con solo una característica a la vez. Los resultados de este conjunto de experimentos llevaron a la primera ley de herencia de Mendel llamada ley de segregación (Bio Libretexts).
