During the process of chromosome replication, A genetic error occurs. As a result, a sequence of events occurs as described belo
bonufazy [111]

Answer: 1. B-D-A-C.

Explanation: If a genetic error occurs during chromosome replication, it will lead to a series of events ranging from:

1) Production of a DNA strand with an altered base sequence.

2) Production of an mRNA strand with an altered base sequence during transcription. This is because mRNA is synthesized by copying the genetic message coded in the DNA.

3). Synthesis of a protein with an altered amino acid sequence during translation, and this eventually leads to

4). The expression of a new inheritable trait in the organism.

Explain the rock cycle by describing how an igneous rock can become a sedimentary rock, then a metamorphic rock, and then an ign
Paraphin [41]
An igneous rock can be formed from cooled magma. The igneous rock can become sedimentary if it is broken down by wind or water. The sedimentary rock can become metamorphic if it becomes buried in the earth, where pressure and heat would turn it into a metamorphic rock. The metamorphic rock can then become an igneous rock by melting underground and turning into magma, flowing out of a volcano, and cooling.

When heart muscles cells are deprived of oxygen, the heart still pumps. what must the heart cells be able to do? transform lacta
katrin2010 [14]
The heart cells must be able to continue aerobic metabolism when skeletal muscle cannot. Aerobic metabolism is a part of cellular respiration and involves body cells making energy through glycolysis, the citric acid cycle, and the electron transport/oxidative. It is done in the heart at a rate below 85% of maximum heart rate and does not use vigorous muscle contraction. fatty acids , ketone bodies and carbohydrates are the primary substrates of the heart metabolized to generate ATP. The metabolic demands of the heart are the largest than any other organ in the body, and normal cardiac metabolism is required to fuel contractile function and viability.

How does water move underground?
bezimeni [28]

Answer:

Groundwater is transported through aquifers because of two main reasons: gravity and pressure. In unconfined aquifers, which we concentrate on because they are more likely to be contaminated, water always flows from high points to low points because of gravity.
