Answer:
Tetraploid wheat evolved by allopolyploidization and subsequent diploid-like behavior due to cytological diploidization
Explanation:
Durum wheat (<em>Triticum durum</em>) or pasta wheat, is a tetraploid wheat species that has 28 chromosomes, i.e., seven pairs in each genome (2n = 4x = 28). Durum wheat was domesticated from wild emmer wheat, which originated by hybridization of two diploid wheat species with 14 chromosomes: <em>Triticum monococcum</em> (genome AA) and one wild progenitor (genome BB). <em>Triticum durum </em>is a typical example of evolution by hybridization and polyploidization, where the resultant tetraploid species has two complete sets of chromosomes. Allopolyploidization is one of the most common types of plant speciation. During meiosis, 28 chromosomes form 14 homologous chromosome pairs, because homologous chromosomes have developed 'restriction of pairing' (i.e., cytological diploidization). The restriction of pairing to fully homologous chromosomes ensures a correct meiotic behavior, which otherwise would be altered due to the high level of homology that still exists among chromosomes from different wheat progenitors.
Answer: The baseball will go farther because of Newton's law. The more mass an object as, the more force needed to move it. The bowling ball has more mass than a baseball so more force is needed to move it.
Explanation:
The statement environmental influences begin at birth and continue throughout life is definitely False.
<h3>What do you mean by Environment?</h3>
Anything which is present in the surrounding of an organism is called its environment. The environment is surrounded by abiotic and biotic factors.
Environmental influences will not remain the same throughout life. If a human is affected by a natural disease, it will definitely be cured with medications. Environmental influences sometimes behave as genetic diseases, which stay long or sometimes endless.
Therefore, the statement environmental influences begin at birth and continue throughout life is definitely False.

<span>The three daily activities that affect homeostasis include;
Temperature, glucose levels, ability lymphatic system.
Homeostasis is the tendency of organisms to auto-regulate and also maintain an internal environment within a stable state. The stable condition is when the optimal functioning of organisms and dependant on many variables.
For example, fluid balance and body temperature to be kept within certain preset limits. PH of extracellular fluid, potassium, calcium ions and concentration of sodium and blood sugar levels are also variables.
It is needed to be regulated despite the diet, environment, level of activities. They are controlled by homeostatic mechanisms which when comes together maintains life.</span>
The environmental effects of an individual or group in terms of resources used and waste produced is an individual or group's ecological footprint (option A).
<h3>What is ecological footprint?</h3>
Ecological footprint is the measure of how much biologically productive land and water area an individual, population or activity requires to produce all the resources it consumes and to absorb the waste it generates using prevailing technology and resource management practices.
Living organisms make use of resources in the environment and these can either leave negative or positive effect on the environment that will affect sustainability.
Therefore, it can be said that the environmental effects of an individual or group in terms of resources used and waste produced is an individual or group's ecological footprint.
