Answer:
Geotropism is the influence of gravity on plant growth or movement. Simply put, this means that roots grow down and stems grow up. ... In this case, the stimulus is gravity. Upward growth of plant parts, against gravity, is called negative geotropism, and downward growth of roots is called positive geotropism.
Explanation:
Mixtures are combinations of several substances. Each of the substances retains its physical properties. There are no new substances created. This is in contrast to a chemical reaction in which two or more reactants make new products.
There are two types of mixtures. The first kind of mixture is a homogenous mixture. Homogenous mixtures are uniform in the ratio of the combination of substances. throughout. All solutions are homogenous mixtures. Colloids (such as mile) and suspensions are also homogenous mixtures, but their particle sizes are larger than the particles that make up a solution. This larger particle size makes colloids and suspensions appear murky or opaque.
The second kind of mixture is a heterogeneous mixture. Heterogeneous mixtures are not uniform throughout. A classic example of a heterogeneous mixture is a trail mix- every handful you grab will be slightly different. If a suspension is allowed to sit, then its large particles will settle to the bottom of its container. At this point, the suspension would be classified as a heterogenous mixture.
Answer:
4)
Explanation:
Gametes have one haploid (n) genome, which is half of somatic cells, having one diploid (2n) genome combined through fertilization from two haploid (n) gametes.
In humans, gametes have 23 chromosomes, and somatic cells have 23 homologous pairs, which is 46 chromosomes.
Different species have different numbers, but most follow the same pattern.
Earthquakes are seismic waves formed in the central area of the earth. Propelling around the earth creating a force that is released on the earths crust creating an earthquake. :)
