Answer: d. a form of a gene
Explanation:
An allele is one of a pair of genes that appear at a particular location on a particular chromosome and control the same characteristic, such as blood type or color blindness. Alleles are also called allelomorphs. Your blood type is determined by the alleles you inherited from your parents.

which of the following is not an example of mechanical weathering?
A. rocks being broken apart from freezing water
B. rocks being apart by plant roots
C. abrasion caused by wind blowing sand against rocks
D. dissolving of lime stone rock by ground water
Answer:
D
Explanation:
Because,
Mechanical weathering is the breaking down of rocks into smaller pieces without changing the composition of the minerals in the rock. This can be divided into four basic types – abrasion, pressure release, thermal expansion and contraction, and crystal growth.
The dissolving of limestone rock by groundwater is not an example of physical weathering.
Another name for mechanical weathering is called physical weathering. Some factors that aid or help in the mechanical weathering of rocks are:Wind, the thawing of frozen water found in rocks, e.t.c
Therefore, the dissolving of limestone rock by groundwater is not an example of physical weathering.
The correct option is option D

An intrinsic igneous rock is formed as results of
Answer:
In essence, igneous rocks are formed through the cooling and solidification of magma ( or lava). As hot, molten rock rises to the surface, it undergoes changes in temperature and pressure that cause it to cool, solidify, and crystallize.

While studying environmental samples collected from the ground cover of the Amazon rainforest, you isolate a new microorganism. You note that it is single-celled, lacks a nucleus, and is found only in areas of the rainforest that remain humid year-round. Based on this information, how would you best describe this organism
Answer:
The organism is a prokaryote from the domain Archaea since it lacks organelles and lives in what can be considered an extreme environment.
Explanation:
The organism is single-celled and lacks a nucleus. Prokaryotic organisms generally lack nuclei and other membrane-bound organelles such as mitochondrion and chloroplast. Hence, both attributes are characteristic of a typical prokaryote although being unicellular is not exclusive only to prokaryotes.
Prokaryotes can be bacteria of Archaea. The organism, in this case, also lives in an area that is humid all year round. Such an area can be considered to be an extreme environment. Living in extreme environments is a characteristic that is peculiar to Archaea only.
Organisms in the Archaea domain are generally prokaryotic, unicellular, and live in extreme habitats such as hydrothermal vents, marshes, hot springs, etc.

Suppose a cool, damp autumn causes the cricket population to greatly increase. What will most likely happen to the frog and snake populations?
Answer:
also increase
Explanation:
more food more animals can eat causing animals to come and also breed then the crickets will go back down causing the predators to go back down giving them a chance to go back up and the cycle continues.

Pluripotent stem cells can turn into any type of cell in an adult body.
Somatic stem cells can only differentiate into specific cells in an organ or tissue.
Insects are a major danger to crop plants. Every year, insect damage destroys many plants that could be used to produce food. Genetic engineering can be used to insert a gene into crop plants that helps them resist insects. What is one potential risk of this use of biotechnology?
Answer:
1. Is it safe to consume a plant/crop that has been injected with genetic engineering?
Genetic engineering may have some risks as well such as production of genetically modified organisms interfere with the environment. The toxins produced by these organisms are found in other higher organisms.
What are the risks of genetic engineering?
Genetic engineering is also called as genetic modification. It is the modification of an organism's genes through the use of technology. It is a set of technologies which are used to change the genetic makeup of the cells, including the transfer of genes within and across the different species boundaries to produce new and improved or novel varieties of organisms. New DNA is obtained through either isolating and copying the genetic material of interest using recombinant DNA methods or through artificially synthesizing the DNA molecule.
Genetic engineering has some potential risks which include transfer of the selected gene into other species, this interferes with the nature, GM crops could be harmful for organisms, for example the toxins produced from these crops have been detected in the body of some organisms.

a. The wavelength is short
b. The wavelength is long
c. Must be a mechanical wave
d. Must be a wave in the electromagnetic spectrum
13. The wave speed of an electromagnetic wave is constant when travelling through a medium. Which formula below is the correct one to use when calculating for wave speed
a. Wave speed = frequency x period
b. Wave speed = period x wavelength
c. wave speed = frequency x wavelength
d. Wave speed = crest x trough
Answer: amplitude would help measure height
low f, constant speed, long wavelength
speed = frequency x wavelength
Explanation: constant speed, low frequency
frequency = speed/wavelength; at constant speed f proportional to 1/wavelength, so low f __> long wavelength
speed = freq*wavelegth

What two locations on a neuron membrane can we find synapses?
Answer:
ONLY IN CONNECTED NERVE CELLS
Explanation:
THE spot of close connection between axon and dendrite is the synapse. A single axon can have multiple branches, allowing it to make synapses on various postsynaptic cells.In the central nervous system, a synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Synapses are found where nerve cells connect with other nerve cells. Synapses are key to the brain's function, especially when it comes to memory.

Autosomal DNA and mitochondrial DNA
Explanation:
There are two types of DNA in the cell – autosomal DNA and mitochondrial DNA. Autosomal DNA is packaged into 22 paired chromosomes.
In each pair of autosomes, one was inherited from the mother, and one was inherited from the father. Autosomal DNA is passed down from both the mother and the father and provides clues to a person’s ancestry.
