Answer:

repulsion (trans)

Explanation:

Repulsion refers to the phenomenon by which each homologous chromosome contains one dominant and one recessive allele from two different linked genes. A <em>trans</em> arrangement occurs when an individual is heterozygous for two linked genes, where the recessive allele for one particular gene is located on the same chromosome as the dominant allele for the other linked gene, thereby dominant and recessive alleles are said to be “in repulsion”. Conversely, a <em>cis</em> arrangement occurs when both dominant alleles are located on one chromosome and both recessive alleles on the other.

Which is required for sexual reproduction? mitosis binary fission diploid cell production meiosis mitosis binary fission diploid
dsp73
Meiosis (SEXUAL cell division) is a type of Mitosis (cell division). 
Diploid cell production happens during meiosis when the haploid (n) cells from the parents divide into TWO diploid (2n) cells (which have the complete set of chromosomes from the parents). 

Basically, meiosis is required for sexual reproduction (unless in your question you can choose more than one answer...so it'll be meiosis, diploid cell production, mitosis)

How can we predict which elements are reactive under normal conditions and which are unreactive?​
mr_godi [17]

Answer:

We can predict or comment about reactivity of elements by taking into consideration their electronic configuration that imparts stability or un-stability to an atom.

Explanation:

Reactivity : It refers to the affinity of a substance to combine with other substance .

Elements are mainly of two types :

  • Metals and Non metals

In terms of metals or non metals it can be defined as tendency to loose or gain electrons .

  • On the basis of it ,we can easily make out or comment about the reactivity of element (metal or non metal ) .Like ,if an element has completely filled outermost shell or we can say have stable electronic configuration then it is already stable .Therefore , it won't react with any other element .
  • But, if its outer shell isn't complete then in order to attain stability it will combine or react with other .Hence , we can say it will be quite reactive .

Why does physarum polycephalum branch out like a plant or fungus?
Olenka [21]

Answer:

Physarum first grows as single-celled amoebae, but the amoebae fuse, and the organism loses its 'cellular' makeup. As the organism continues to grow, nuclei divide without cell division. The resulting bag of nuclei is called a 'coenocyte' or 'plasmodium'.

Explain how weather,climate,and seasons could affect the biotic and abiotic factors of an ecosystem
Vilka [71]

Weather, climate and seasons are factors that limit the distribution of different species of living beings in ecosystems, influencing survival and reproduction.

<h3>What are the biotic and abiotic factors of an ecosystem?</h3>

Biotic factors are each of the living organisms of an ecosystem and abiotic factors are all non-living ones such as organic and inorganic substances in the system as well as environmental conditions.

Weather, climate, and seasons could affect these factors in altering the distribution of species, but would also decrease primary production, which would affect survival and growth.

Therefore, we can conclude that the weather, climate and seasons are factors that limit the distribution of different species of living beings in ecosystems, influencing survival and reproduction.
