Answers
Answer:
The correct answer would be - option B.
Explanation:
The diagram given in option B where all the chromosomes are aligned in the center of the cell and there are microtubules attached to it and pull on different sides of the pole are seen correctly represents the missing diagram of the stage of mitosis cell division.
It correctly represents the metaphase stage of the mitosis that comes between prophase, where condensation of chromosomes takes place, and anaphase.

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
Answers
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.

Answer:
Varicose veins are twisted, enlarged veins. Any superficial vein may become varicosed, but the veins most commonly affected are those in your legs. That's because standing and walking upright increases the pressure in the veins of your lower body.

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.

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?
Answers
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).

In the _____ the virus can reproduce so rapidly that it causes the cell membrane to disintegrate.
a lysogenic
b lactic
c lymphatic
d lytic
Answers
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.

Watch this video about the temperate forest biome. Explain how the organisms in this forest biome adapt to their environment. Also explain how the parts of the biome work together as a system.
Video : https://app.edmentum.com/content-delivery/resource/0ed4cd61-cec6-428b-a8e4-a38d3f388707
Answers
Answer:
By changing their appearance.
Explanation:
The organisms in this forest biome adapt to their environment by change their physical appearance according to the climatic conditions of the environment. When there is cold winter season, most of the animals hibernate such as snake, and lizard etc and come out when summer season started, while on the other hand, the big animals grow thick fur which helps them to survive in that cold winter. In biome, animals and plants that have common characteristics exists in the same environment so the plants provide food to the herbivore whereas herbivores provides food to the carnivores so these parts of biome work together to achieve stability.
Answer:
In winter, the forest is extremely cold. The roots of the evergreen plants are unable to access water. The needle-like structure of these trees minimizes water loss from transpiration. The needles are also dark in color. The color allows them to absorb maximum sunlight for photosynthesis. Even with little food, the animals in the biome can access food from these trees. Squirrels can eat the seeds from the pinecones. Crossbill birds have special beaks that allow them to access the seeds. Moose eat sappy twigs. They’ve also adapted to build fat reserves to help them survive the harsh winter. Some animals hibernate, and others migrate to warmer places to survive the winter. During summer, the long days allow abundant photosynthesis. So, there’s increased plant growth accompanied by increased insect activity. Trees with seasonal leaves develop new leaves. Birds that had migrated return during the summer, when food is readily available. The plants and animals work as a system to obtain an adequate food supply throughout the year.
