Which structure is highlighted and indicated by the leader line?
Answer:
glomerulus and glomerular capsule.
Explanation:
The highlighted structure is glomerulus and glomerular capsule .
What is glomerular capsule?The glomerulus is covered by a two-layered pouche known as bowman's capsule and the space in between both the walls of the capsule is called bowman's space. Bowman's capsule is also known as malphigian capsule.
The glomerular capsules are located in the outer part of the kidney, known as the cortes. The main function of glomerulus capsule is to filter plasma that lead to a production of glomerular filtrate.
The glomerular capsule contain a cluster of microscopic blood vasle and capillaries known as glomerulus were waste product are filterd from the blood. The space in between both the walls of the capsule is called bowman's space. Bowman's capsule is also known as malphigian capsule.

what property of DNA makes it possible for a probe to find a single-stranded DNA target gene?
Answer:
base pairing property
Explanation:
every dna/rna base, a c g t and u, has only one possible pairing partner, so if the strand is open on one side (single strand), the opposite side can be inferred because only one sequence will match the existing strand's base sequence. the property is usually called base pairing property
A pea plant purebred to produce round yellow peas is crossed with a plant purebred to produce wrinkled green peas. Round pea shape is dominant to wrinkled, and yellow pea color is dominant to green. Members of the resulting F1 generation are then crossed to produce an F2 generation, as shown in the figure. On average, what fraction of the F2 generation will display both dominant traits?
(ANSWER ONLY IF YOU ARE SURE PLEASE NO GUESSING THANK YOU)
A)
4 out of 16 plants will display both dominant traits.
B)
9 out of 16 plants will display both dominant traits.
C)
16 out of 16 plants will display both dominant traits.
D)
12 out of 16 plants will display both dominant traits.
The fraction of the F2 generation that will display dominant traits will be 9/16. The correct option is B.
Dihybrid crossLet us assume that pea shape is represented by A (a) while color is represented by B(b).
Purebred round yellow peas = AABB
Purebred wrinkled green peas = aabb
F1: AABB x aabb
all AaBb
F2: AaBb x AaBb
A_B_ = 9/16
A_bb = 3/16
aaB_ = 3/16
aabb = 1/16

Part B: Find Credible Sources When designing a science presentation, look for credible sources. Science doesn’t show bias, but humans do. Avoid sites and articles that provide facts without citing proper scientific evidence. You must be able to identify reliable sites so that the data in your presentation is credible. Use sources that end in .gov, such as CDC.gov. These government sites are reliable sources. You can also use sites ending in .edu. They are usually trustworthy, but sometimes students, not scientists, write content for .edu websites. Always identify the source’s author before proceeding. Some .org and .com sites are credible, but it’s important to verify their authenticity. When reviewing a source, ask these questions: Who is the author? Is this person an HIV or AIDS expert? What is the document’s purpose? Does the document state facts that scientists can prove with evidence? Are there opinions in the document? How old is the document? Do other credible sources support the statements in the document? Search for credible websites and note the information they contain. Write down two sources that you will use for your presentation, and cite them using Modern Language Association (MLA) citation methods.
Authors whose work is regarded in their fields of the study write credible sources. Authors who are trustworthy and responsible will cite their sources so that you can verify the truthfulness of and support what they have written.
In the combustion process, oxygen and biomass are mixed in a hot atmosphere to produce carbon dioxide, water vapor, and heat. When sulfur dioxide and nitrogen oxides are released into the atmosphere and are carried by the wind, acid rain results. Fossil fuels differ from biomass in that they discharge carbon dioxide into the atmosphere. The approximate chemical formula for coal In terms of producing the most energy per unit of carbon dioxide released, natural gas is the best fossil fuel. Because a new crop can be planted after each harvest, biomass is a renewable resource and a low-carbon fuel. On carbon support, tungsten carbide and nickel form the catalyst. It is more plentiful, uninterrupted use is possible, and it is cleaner than fossil fuel.

As a consequence of infection by a temperate bacteriophage such as lambda, the host cell:.
The host cell may lyse or may continue to divide and replicate both itself and the prophage.
What is the effect of temperate bacteriophage on a host cell?Lytic cycle:
The infecting phage kills the host cell at the end of the lytic cycle, also known as a virulent infection, to create a large number of its own offspring. The phage genome immediately produces early proteins that degrade the host DNA after being injected into the host cell, enabling the phage to take over the cellular machinery.
The remaining proteins needed to construct fresh phage particles are subsequently synthesized by the phage using the host cell. The new genetic material is packed into the head while new daughter phage particles are built, and the heads and sheaths are created independently. In the course of this process, phage enzymes gradually weaken the host cells, which eventually burst, dispersing 100–200 additional phage progeny into the environment.
Lysogenic cycle:
The lysogenic cycle, also known as temperate or non-virulent infection, uses the host cell as a haven where it can survive in a latent state. It does not harm the host cell. After the phage DNA is injected into the host cell, it uses integrases encoded by the phage to integrate into the host genome, at which point it becomes known as a prophage.
The host cell divides for the duration that it is there and does not create the proteins necessary to make progeny, at which point the prophage genome is passively copied alongside the host genome. The bacterial hosts are typically somewhat unaffected by this procedure because the phage genome is typically quite tiny.

The poles experience all four seasons.
The poles never get any direct sunlight.
The poles have daily equal amounts of sunlight and darkness.
They both get the same amount of sunlight.
The poles never get any direct sunlight.
They both get the same amount of sunlight.
Because they receive no direct sunshine, the Arctic (North Pole) and Antarctic (South Pole) are both chilly. Even at the height of summer, the Sun is low on the horizon. The Sun doesn't rise at all for several months during the winter since it is so deep below the horizon hence poles don't have equal amounts of sunlight and darkness.The poles receive less energy and heat from the sun because of the tilt of the earth and its orbit around the sun. There are just two polar seasons as a result: summer and winter.The tilt of the Earth's axis causes the Poles to experience around six months of day and six months of night. Due to this tilt, each Pole spends roughly six months angled both toward and away from the Sun. The North Pole experiences six months of nonstop daylight when it is inclined toward the Sun.In the winter, the Sun sets for extended periods of time since it is so deep below the horizon. Therefore, the days are chilly and dark, much like the nights.
