Answer:
his continental drift
Explanation:
Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. ... Wegener suggested that these creatures were alive in warm climate zones and that the fossils and coal later had drifted to new locations on the continents.
how are the functions of the endocrine system and nervous system similar?
Answer:
It's similar to the nervous system in that it plays a vital role in controlling and regulating many of the body's functions. However, while the nervous system uses nerve impulses and neurotransmitters for communication, the endocrine system uses chemical messengers called hormones.
if mammalian cells receive a go-ahead signal at the g1 checkpoint, they will:
If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.
What is the Cell Cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next nuclear division.
There are three major checkpoints in the cell cycle. One at the end of the G1 phase, the second at the end of the G2 phase, and while third is during the M phase.
Therefore, if mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.

Which two body systems control homeostasis?.
Answer:
The two body systems that control homeostasis are the nervous system and the circulatory system.
Explanation:
The nervous system controls everything you do, including voluntary and involuntary actions, and the circulatory system transports important nutrients to your cells to maintain a stable inner environment.
Body size in mice (length from nose to base of tail) is controlled in part by genetics. The following data shows the number of mice grouped by lengths:

complete dominance
polygenic
incomplete dominance
pleiotropic
Answer:
polygenic!
Explanation:
Based on this data and your knowledge of inheritance patterns, identify the inheritance pattern that this trait follows in mice is polygenic.
What is Polygenic inheritance?Polygenic inheritance occurs when one character is controlled by two or more genes.
Often the genes are large in quantity but small in effect. Examples of human polygenic inheritance are height, skin colour, eye colour and weight.
Thus, option "B" is correct.

Answer: Researchers argue that robust Australopithecines should be classified in a separate genus called Paranthropus.
Explanation: The "robust" australopiths are a group of fossil hominins that existed in East and southern Africa between approximately 2.5 and 1.4 million years ago (Ma). They are referred to here as members of the genus Paranthropus, though considerable disagreement about their proper taxonomy persists. (credit to the internet)

Axons from higher brain centers form motor tracts that descend from the brain into the white matter of the spinal cord and then synapse with somatic motor neurons in the ____________.
Motor output that is gotten from the spinal cord to skeletal muscles involves somatic motor neurons of the anterior gray horn. Many somatic motor neurons are regulated by the brain. Axons from higher brain centers form motor tracts that descend from the brain into white matter of spinal cord and then synapse with somatic motor neurons either directly or indirectly by first synapsing with interneurons that in turn synapse with somatic motor neurons.
Sensory receptors is known to detect sensory stimulus.
Sensory neurons often convey sensory input by nerve impulses through their axons. Their axon often start from sensory receptors into the spinal nerve and into posterior root.
From posterior root, axons of sensory neurons have 3 different choices of paths.
Axons of sensory neurons does start into the white matter of the spinal cord and moves up to brain as part of sensory tract.Axons of sensory neurons sometimes do moves into the posterior gray horn and synapse with interneurons that has its axons extend into the white mater of spinal cord and thereafter moves to brain as sensory tract.Axons of sensory neurons oftens moves into the posterior gray horn and synapse with interneurons which the synapse with somatic motor neurons.Axons that is gotten from spinal cord often synapse with other motor neurons in PNS.

transcription starts with ____ and makes ____ with the aid of ____________
Answer:
transcription starts with Initiation/the nucleus/DNA and makes mRNA with the aid of Polymerase RNA enzyme
Explanation:
Transcription is the process in protein synthesis consisting of a starting process of initiation where the nucleus hosts the creation of an mRNA sending the coding message to the ribosome, but the starting process is the Polymerase binding to a site on the DNA strand, then it makes the mRNA through the other steps in transcription.

Monomers can be thought of as
A. highly unstable compounds.
B. Lego pieces or building.
C. long chain compounds.
Answer: B
Explanation:
Monomers are atoms or small molecules that bond together to form more complex structures such as polymers (which are long chain compounds)
Monomers are long chain compounds. So, the correct option is (C).
What are Monomers?A monomer is defined as a molecule which can react with other monomer molecules to form a larger polymer chain. It is also a three-dimensional network formed by a process called polymerization.
These are the molecules of any of a class of compounds mainly organic compounds which can react with other molecules to form very large molecules known as polymers.
Examples of monomers are glucose, vinyl chloride, amino acids and ethylene where each monomer is linked to form different types of polymers like glucose, glycosidic bonds which link sugars to form polymers like glycogen, starch and cellulose binds monomers.
Thus, Monomers are long chain compounds. So, the correct option is (C).

why not test for pathogens like salmonella directly rather than use an indicator organism such as a coliform?
Indicator organisms are organisms that are utilized to detect the presence of another organisms that cannot be easily identified.
We do not test for pathogens like salmonella directly but use an indicator organism like coliform because these pathogens are not easily isolated and they are much harder to identify.
Pathogens like salmonella are not tested for directly because they are much lower in numbers when found in wastes or waterbodies and to identify them directly is expensive.
Also testing directly for these micro-organisms is very expensive and non-viable. So it is better to use indicator organisms to detect their presence.
