What is the correct order of events: Homologous chromosome separate Chromosome condenses Lining up on metaphase plate, Crossing

over Pairing up to form tetrad
Biology
1 answer:
Sedbober [7]3 years ago
7 0

Answer:

Chromosome condenses

Pairing up to form tetrad

Crossing over

Lining up on metaphase plate

Homologous chromosome separate

Explanation:

Condensation of chromosomes occurs in prophase I phase. Pairing up to form tetrad occur during prophase I. Crossing over occurs during prophase I of meiosis cell division. Chromosomes line up along the metaphase plate in the stage of Metaphase. Centromeres break down and homologous chromosomes separate in anaphase I phase of meiosis.

The efficiency of a car’s engine is 14 percent. This implies that the engine wastes
Harlamova29_29 [7]

Answer:

C) 86 J of energy for every 100 J that enter it.  

Explanation:

Efficiency is a measure of performance of an engine which can be calculated by the formula as given below to get in percentage:

           Efficiency = energy output/energy input x 100

If the efficiency of a car’s engine is 14 percent it means that for every 100 joules of energy that is entered into it, only 14 joule is converted into useful output and rest of the 86 Joules is wasted.

The efficiency of any machine is never 100%, however, if any machine miraculously converts all the input energy to useful output energy, it means it is 100% efficient.

Hope it helps!

Which of the following statements correctly describes how Mendel accounted for the observation that traits had disappeared in th
Genrish500 [490]

Answer:

A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.

Explanation:

Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.

When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.

_______ cause(s) populations to change over time.
vekshin1
The answer is B., Natural Selection.

Weather certainly doesn't change populations, and genes only caused individuals in a population to be slightly ( genetically-wise ) different from the others. It does cause change, but not change in the whole population over time.
Natural disasters don't change the populations over time either. Natural disasters only caused change in their environment, at most.

So, the only answer left is natural selection, and it makes sense too! 
Natural selection is the process where the individuals with better traits suited to survive in that specific environment live on and give those good traits to their offspring.
The individuals with less suited traits to survive will die out, and will not be given an opportunity to reproduce and pass on their less suited traits, so over time, the population will increase of individuals with better suited traits to survive and the individuals with less suited traits will eventually die out, therefore making the entire population change.

Hope I helped you!
