The water in an artesian well comes from a/an _______ aquifer. A well not only has to reach the _______ but also has to go deeper. _______ aquifers are more prone to pollution. The two primary components of a septic system are a septic tank and a/an _______. Groundwater that comes to the surface naturally is known as a/an _______.
Answer:
nitrates; cone of depression; confined; water table; unconfined; drainage field; spring.
Explanation:
Nitrogen-fixing bacteria in soil can convert excess nitrogen into nitrates, which can contaminate groundwater.
A cone of depression forms around a well when the water table begins to slope toward the well.
The water in an artesian well comes from a confined aquifer.
A well not only has to reach the water table but also has to go deeper.
Unconfined aquifers are more prone to pollution.
The two primary components of a septic system are a septic tank and a drainage field.
Groundwater that comes to the surface naturally is spring.

Hepppp!!! The American curl is a type of cat with curled ears. A single gene with two alleles codes for the ear-shape trait. The dominant allele (R) codes for curled ears, and the recessive allele (r) codes for straight ears. If two curled ear cats produce a kitten that has straight ears, what is the genotype of the parent cats? a Rr x Rr b RR x RR c RR x Rr d Rr x rr
Answer:
Rr Rr
Explanation: The parents of the cat have to have an R allele to be a curled cat, but they can't be RR because that is a dominant gene, meaning that the recessive trait cannot happen. This means that the parents have to have a recessive trait, which means that they are heterozygous.

Which shows three human body parts in order from the simplest level of organization to the most complex? red blood cell → nervous system → bone tissue nervous system → bone tissue → red blood cell red blood cell → heart tissue → circulatory system bone tissue → red blood cell → nervous system
Answer:
Red blood cell->heart tissue->circulatory system
Explanation:
Cell is a basic unit of any living organism. A tissue consists of many cells. Several tissues make up an organelle. Many organelles contribute to a system
The human body parts in order from the simplest level of organization to the most complex is: red blood cell → heart tissue → circulatory system. Thus, the correct option is C.
What is Body organization?The human body is organized at different levels. The basic level from where the organization starts is the cell. Cells are the basic unit of life. They are organized into tissues, and tissues are further organized to form organs. Different organs are organized into the organ systems such as the reproductive system, respiratory system, and muscular systems.
In this case, the organization of body parts from the simplest level to the most complex level is as follows: red blood cell → heart tissue → circulatory system.

Which of the following is a property of life shared by prokaryotic cells and eukaryotic
cells, but not viruses?
Answer:
Explanation:
. The ability to process energy through metabolism. viruses cant reproduce without a host cell either
Viruses do not possess the tendency to process energy via metabolic reactions.
Difference between viruses and other cells:Viruses are acellular, that is, they do not comprise any cellular organelles, and fail to divide and grow by its own.
Due to this viruses fail to carry out any kind of metabolic reactions, on other hand, prokaryotes and eukaryotes possesses the tendency to perform independent metabolism.
As viruses are not cells, they can only replicate and assemble within a living host cell, which can be a prokaryote or an eukaryote.
Thus, viruses cannot carry any kind of metabolic reactions while prokaryotes and eukaryotes can.
