How does a Covalent Bond Form? ( No goo.gle ik the goo.gle answer cause i tryed looking it up if you put tht answer u wont get brainliest)
Answer:
A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions. Shared electrons located in the space between the two nuclei are called bonding electrons. The bonded pair is the “glue” that holds the atoms together in molecular units.

How can a temporary lake create salt flats in Death Valley?
Answer:
A temporary lake create salt flats in Death Valley when Holocene lakes began to evaporate.
Explanation:
"Each time it has rained since, a new layer has been added. The flat is a vast area covered in salt that was deposited from evaporated water. When the water runs down the mountain, it dissolves minerals that precipitate out as the water evaporates."

Cystic Fibrosis is an autosomal recessive disease. A carrier male is married to a carrier female. What is the chance they will have a child with cystic fibrosis?
Answer:
If only one of you is found to be a carrier, the chance that you will have a child with CF is very low, although not completely eliminated. If you are both carriers, each pregnancy will have a 1 in 4, or 25 percent chance of being affected with cystic fibrosis.

Imagine that you are a scientist who has discovered a new object. You want to find out if the object is biotic or abiotic. You observe several characteristics about the new object. Which of these characteristics would tell you that the object is abiotic, or not alive?(1 point)
The object cannot create energy.
The object has a crystalline structure.
The object can mutate.
The object responds to stimuli.
Answer:
the answer is the object cannot create energy
Explanation:
i just got it right on my quick check
The characteristic that would tell if an object is abiotic or nonliving is if the object cannot create energy.
The capacity to create energy for the normal functioning of the body is one of the key characteristics of living organisms. This energy is usually gotten from the breakdown of food materials through a process known as respiration.
Respiration could be in the presence (aerobic) or absence (anaerobic) of oxygen but the ultimate end is to generate energy, usually in the form of ATP, for metabolism.
Thus, any object that lacks the capacity to carry out respiration cannot be considered to be living or biotic.

22. Why do you think the sea urchin was chosen to test the effect of changes in pH?
Answer:
as it settles deeper underwater ph tends to be higher and a sea urchin tends to be more resilient to change
Acidic seawater, at current pH levels found in the world's oceans, can have a negative impact on sea urchin larval development so it is taken to test the effect of changes in pH.
What is sea urchin?Sea urchins are spiny, globular echinoderms of the Echinoidea class. The urchins were able to compensate for internal pH in modest acidification (pH 7.8) and not in higher acidification (pH 7.6).
The pH of coelomic fluid was lower at higher temperatures.
Thus, due to this, the sea urchin was chosen to test the effect of changes in pH.

The shape of North Carolina's Twelfth Congressional District, shown above, is most likely the result of - (A) watershed boundaries B) gerrymandering (C) county boundaries (D) decentralization (E) amalgamation
Answer:B gerrymandering
Explanation:i had this on a test
The majority of states give the state legislature main power over the process of drawing congressional and state legislative districts. Thus, option B is correct.
What gerrymandering shaped North Carolina's?The admittance of Dakota Territory as two states rather than one is a remarkable example. Regardless of its population, each new state carried a minimum of three electoral votes under the standards for representation in the Electoral College.
On February 11, 1812, the first “gerrymander” was sketched on a map and made official. The redistricting plan was approved by Elbridge Gerry, the governor of Massachusetts at the time, in order to maintain his party's hold on power in the forthcoming election.
Therefore, gerrymandering shape of North Carolina's Twelfth Congressional District.

Scientists are now studying human DNA in labs all over the world. Which are current goals for the scientists at these labs? Select three answers that apply. A. completing a full sequence of human DNA (the Human Genome Project) B. identifying the regions of human DNA that are transcribed into RNA C. identifying the regions of human DNA that bind to proteins D. analyzing the regions of human DNA that vary among individuals E. describing the molecular structure of human DNA
Answer:
B. identifying the regions of human DNA that are transcribed into RNA
C. identifying the regions of human DNA that bind to proteins
D. analyzing the regions of human DNA that vary among individuals
Explanation:
The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.
