piece o paper

Explanation:

²³⁴Th → ²³⁰Ra + ⁴He

Properties of alpha radiation:

Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number 4 less than and atomic number 2 less than the starting atom.

Alpha radiations can travel in a short distance.

These radiations can not penetrate into the skin or clothes.

These radiations can be harmful for the human if these are inhaled.

These radiations can be stopped by a piece of paper.

In what way do two alleles for the same trait differ?

Alex17521 [72]

There is Homozygous Dominant which is two dominant alleles, then Homozygous Recessive which is two alleles that will only be shown if it is paired with heterozygous which is a Dominant and recessive. I hope that makes sense, sorry i’m bad at explaining but if it doesn’t I can try and explain it again.

1. Which of the following might be a result of adding a secondary consumer to the aquatic ecosystem in the accompanying illustra

MatroZZZ [7]

Answer:

Option-(A): In an illustrated flowchart, the movement of carbon atoms through an aquatic food chain is indicated by arrows.
Option-(C)- An increase in the population of scavengers.

Explanation:

The ecological pyramid is comprised of different level of organisms as the energy flow occur through them in a more directed form inside the different spheres depending upon the medium for energy transmission across the given parameters or area. As, the arrow provides us with a more directed way for understanding the transmission of energy through different organisms and there respective levels inside the ecological pyramid.

While, the increase in the level of scavengers or the animals which consumes the left overs of other living beings is balanced with the addition of the secondary consumers to the aquatic ecosystem.As, it will provide equal chances and energy to the different beings inside the ecosystem.

A learner was walking along a road when she saw an object under a tree. When the learner touched the object, it rolled over and

valentina_108 [34]

Answer:

growth, reproduction, and sensitivity

Explanation:

The characteristics of living organisms displayed by the object are growth, reproduction, and sensitivity.

When the organism reacted by rolling over in response to touch from the learner, it was displaying sensitivity. Sensitivity has to do with the ability of living organisms to be sensitive to things such as touches.

When the object divided, it was displaying growth and reproduction that are characteristics of living organisms. Growth can be defined in this case as an irreversible increase in the number of cells and reproduction can be defined as the production of new individuals.

By dividing into 2, the object has increased its number of cells and has also produced a new individual.

Hence, the characteristics of living organisms shown by the object are growth, reproduction, and sensitivity
