Answer:

contraction and relaxation of the heart

Explanation:

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.

Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

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.

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.

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.

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.

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.

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.

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."
