Answer:
Explanation:
Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve.
Answer:
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

Answer:
Huntington disease is a dominant autosomic disease so it presents either in heterozygosity (Aa) or in homofzigosity (AA)
observing the pedigree, the two parents have the Aa genotype so by making the punnet's square we have as possible genotypes: AA, Aa, Aa, aa. So the chance to get the disease is 25%

Which option lists materials in order by their ability to allow the flow of
electrons, from least easily to most easily?
A. Insulator, semiconductor, conductor
B. Conductor, semiconductor, insulator
c. Semiconductor, insulator, conductor
O D. Semiconductor, conductor, insulator
The correct option that lists materials in order by their ability to allow the flow of electrons, from least easily to most easily, is Insulator, Semiconductor, and Conductor, which is in Option A.
What are an electron, an insulator, etc.?The ability of a material to conduct electricity depends on the number of free electrons that are available to move through the material. In an insulator, there are very few free electrons, which means that the material does not conduct electricity very well. Insulators are typically used to prevent the flow of electricity, for example, in electrical wiring, where plastic or rubber coatings are used to insulate the copper wires.
Hence, the correct option that lists materials in order by their ability to allow the flow of electrons, from least easily to most easily, is Insulator, Semiconductor, and Conductor, which is in Option A.

Which representation of data visualizes potential relationships between variables?(1 point) a table a graph a chart a list
Answer:
A chart
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A chart is a representation of data which visualizes potential relationships between variables. Some examples include pie chart, bar chart, etc.
A bar graph also known as a bar chart can be defined as the graphical representation of data (informations) by using vertical columns or rectangular bars. When a data set is observed, a bar chart can be used to graphically represent or record the total or overall amount of information contained therein. Generally, bar charts are used for the comparison of informations obtained from a data collection by representing each value (information) with rectangular bars respectively.

What might happen to the cell if it were suddenly unable to use lipids?
A. It would not be able to make proteins or transfer substances to other cells
B. would not be able to transfer genetic information to other cells
C. It would not be able to store energy or communicate with other cells
D. It would not be able to store water or protect itself from viruses
Explanation:
I don't know the exact answer but I can tell you that lipids are considered the building blocks of cells . the body uses lipids as a storage for energy and insulation and to make cell membranes. without lipids the cell will die . the way lipids function is .... lipidsfunction as an energy reserved regulate hormones transmit nerve impulses cushion vital organs and transport fat soluble nutrients.

In the _____ the virus can reproduce so rapidly that it causes the cell membrane to disintegrate.
a lysogenic
b lactic
c lymphatic
d lytic
In the lytic cycle, the virus introduces its genome and replicates after that it assembles a new virus body and ruptures the cell membrane, hence option d is correct.
What are the lytic and lysogenic cycles?In a lytic cycle, the virus transfers its genome into a host cell and starts replication by seizing control of the host's cellular machinery.
When the infection is finished, the host cell is lysed, releasing the freshly duplicated and assembled virus particles into the surrounding waters.
The virus replicates by integrating its genome with the genome of the host cell during the lysogenic cycle, which is also known as a non-virulent infection.
Therefore during the lytic cycle, the virus-cell membrane is disintegrate and the lysogenic cycle happens without killing the host, hence option d is correct.

Why do we observe that superficial, varicose veins are more common in the lower extremities than in the upper extremities?

How would transcription of the E. coli trp operon be affected by changing the two Trp codons in the leader peptide gene to His codons?
Answer:
The attenuation system would respond more to histidine (His) than to tryptophan (Trp) levels
Explanation:
In genetics, the attenuation system refers to the process of control which is responsible for triggering premature termination of transcription in bacterial operons. In bacteria, the process of attenuation is characterized by the presence of an attenuator, which is a stop signal sequence found in the leader mRNA. The tryptophan (trp) operon, which is a cluster of genes responsible to encode the components required during the production of tryptophan, is controlled by the attenuation system. When there is a high tryptophan level, the ribosomes are able to translate an attenuator sequence, thereby resulting in termination of transcription. The attenuation system also controls the synthesis of other amino acids including histidine (His), phenylalanine (Phe) and threonine (Thr).

Species richness is the number of different species represented in an ecological community, landscape or region.
What is species richness?
Species richness is the number of species within a defined region. The species richness of a region is obtained through sampling or via a census.
What determines the number of species in a community?
The number of niches present in a community determines the number of species present. If two species have the exact same niche (e.g. the same food demands) then one species will outcompete the other.
