The complementary base strand to the DNA sequence ATGGCTA is TACCGAT.
O True
O False
True, the complementary base strand to the DNA sequence ATGGCTA is TACCGAT, hence option A is correct.
What is the complementary base in DNA?Deoxyribonucleic acid, or DNA, is a kind of genetic material. The polynucleotide chain is very lengthy.
Deoxyribose sugar (a molecule containing carbon), phosphate group, and nitrogenous bases make up each nucleotide (nitrogen-containing compound).
There are two types of nitrogenous bases: pyrimidine and purines, which include adenine and guanine (consisting of Cytosine and Thymine). Guanine forms three hydrogen bonds with cytosine whereas Adenine couples with thymine through the formation of two hydrogen bonds.
Therefore, the complementary base strand to the DNA sequence ATGGCTA is TACCGAT, hence option A is correct.

Identify ONE process that causes the metamorphism of an igneous rock into a metamorphic rock.
Answer:
Heat
Explanation:
Contact metamorphism happens when hot magma or lava comes into contact with rocks, causing a small area to change into a metamorphic rock. Contact metamorphism will be present on the outside edges of igneous intrusions.
Heat and/or pressure causes the metamorphism of an igneous rock into a metamorphic rock.
What is metamorphic rock?Metamorphic rocks refer to as some other type of rock, but have been substantially changed from their original igneous, sedimentary form. Metamorphic rocks formed when rocks are subjected to high heat, high pressure, hot mineral fluids or, more commonly, some combination of these factors.
Contact metamorphism occurs in rock exposed to high temperature and low pressure, as might happen when hot magma invades into or lava flows over pre-existing protolith. This combination of high temperature and low pressure generates numerous metamorphic facies.

what cause's cell division
Cells divide for many reasons. For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. ... When organisms grow, it isn't because cells are getting larger. Organisms grow because cells are dividing to produce more and more cells.
Answer:
Explanation:
Cells in an organism go through division all the time. One reason is for growth. As an organism grows, more cells are created. Cells divide instead of grow because there is an optimal size for cell. So it is more efficient to create new cells.
Second reason for cell division is to repair damaged cells. Some cells like skin cells are damaged routinely and cell division is the way to repair and replace damaged cells.
Last reason is for reproduction. All organisms use cell division to reproduce.

What are exoskeleton?In comparison to the internal skeleton of a human, an exoskeleton is an external skeleton that endorses and safeguards the body of an animal.
Some of the larger exoskeletons are referred to as "shells" in popular parlance.
The exoskeleton is made up of two layers: a thin outer nutrient layer called the epicuticle and a tough outer inner chitin-protein layer called the procuticle.
The epicuticle of most terrestrial arthropods, such as insects and spiders, contains waxes that aid in reducing evaporative water loss.
Hair and fur are molecularly indistinguishable because they are made of the same keratin.
Thus, the correct option is D.

Ouch. You step on a tack and jrk away without even thinking. Then you decide to pick up the tack and put it on your desk. Which body systems are involved?
Answer: The body systems that are involved are:
--> Nervous System and
--> muscular system.
Explanation:
The body is made up of different organ systems which usually works together to bring about proper functioning of the living organism. Examples of the body systems includes:
--> The nervous system: This system enables the animal to detect and respond to stimuli rapidly.
--> The muscular system: This system enables the organism to move from one location to another.
Both the nervous system and the muscular system work together to bring about coordination of activities. When you step on a tack and jeck away, sensory receptors detects stimuli from the external environment and pass the information received as an electrical impulses to the brain through the nerve fibres. The information is processed in the central processing region which is the brain.
The effectors such as the muscles goes into action upon receiving nerve impulses from the brain. Such actions includes muscular contractions which helps you to pick up the tack and put it on your desk.
Which of the following describes an impact of floods on ecosystems?
Answer:
Soil erosion.
Explanation:
Soil erosion is the impact of floods on ecosystems because the floods moves very fast which takes soil with itself. Due to soil erosion, the productive layer of the soil or the layer in which nutrients are present are eroded which has a negative impact on the plants due to unavailability of nutrients. The floods moves very fast and the soil has no the ability to hold its particle tightly which leads to erosion of the soil that negatively affected the ecosystem.
