"Gravitational attraction" is initially responsible for the formation of the clumps of matter within this interstellar cloud.
<u>Answer:</u> Option C
<u>Explanation:</u>
About 4.6 billion years ago, the solar systems were a bunch of gases and dusts, referred to solar nebula. Gravity squeezed the material as it started to rotate, creating the sun at the middle of the fog.
The rest of the material began to accumulate with the sunrise. The smaller particles moved together to form larger particles that were connected by gravity. As lumps develop, gravity increases and turns into kinetic energy of moving particles that collide and produce heat.
Answer:
Mendel was an Austrian monk whose researches laid the foundation of genetics. The experiments conducted by Mendel led him to the foundation of two laws which are named as the law of segregation and law of independent assortment.
According to the law of segregation, the two alleles of a gene segregate during the time of gamete formation and there are 50-50% chances of each of the alleles to be received by the gametes. Hence, there are 50% chances for Y gametes to be produced and 50% chances for y gametes to be produced.

Answer:
Herbicide essentially replaces sugar with itself during uptake by plants.
Explanation:
Noting that the pH is decreased around the plant cells indicate that there is an acidic environment that exists, It also indicates that the cell wall had been perforated and the contents are being expelled or at the very least leaking.
The ability for the plant to break down and use sugar is vital for its survival. Most herbicides are in the form of glycophosphates and it moves along with the sugar in the plant that have been treated with herbicides through the transport vesicles, the xylem and phloem.
This causes an imbalance in the available sugars that are able to be taken up by the plant since much of it is replaced by the herbicide.
Answer:
The societal, ecological, or technical constraints that resource managers consider before proposing solutions include the Herculean task of trying to find solutions that don’t worsen or lead to a long-term problem.
Another one is that the mining and use of renewable resources should not exceed regeneration rates as it could lead to scarcity of the said resources.
