Explanation:
An enzyme known as rubisco enables plants to use large amounts of
carbon dioxide. This enzyme is most likely active in the
O (1) nucleus
O (2) vacuoles
O (3) mitochondria
O (4) chloroplasts
The enzyme rubisco is most likely active in the chloroplasts.
• In the chloroplasts of the plants, the enzyme rubisco is present.
• It takes part in fixing atmospheric carbon dioxide at the time of photosynthesis and in oxygenation of the resulting compound at the time of photorespiration.
• Rubisco is the name given to the enzyme ribulose-1,5-bisphosphate, which catalyzes the carbon dioxide entry into the photosynthetic metabolism, monitors the pool sizes of essential photosynthetic intermediates, and provides acceptor molecules, which consume the products of the light reactions of photosynthesis.
Thus, option 4, that is, chloroplasts is correct.

Use the information gathered in the A Three Point Test Cross animation to answer the question. Genes H and K are linked and are known to be 3.5 m.u. apart on the same chromosome. What is the recombination frequency between H and K
Answer:
3.5 percent (3.5%)
Explanation:
In genetics, crossing over or 'recombination' refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis I. The map units (m.u.), also known as centimorgans, represent a measure of genetic linkage between genes/loci located on the same chromosome. One map unit (1 m.u.) is equal to a 1 percent chance that two gene/loci (in this case, genes H and K) will be separated during meiosis by recombination. In the example above, it means that among their progeny, 3.5 percent (3.5%) will be recombinant for the two genes (H and K), and 96.5 percent (96.5%) will have the parental combination of these genes.

Refer to the Biochemistry in Focus section of your text for this chapter to answer this question. A mutation in Complex I decreases the efficiency of the electron transport chain. However, not all components of the electron transport chain are affected by this mutation. Which component of the electron transport chain will remain unaffected by a mutation in Complex I
Answer:
Complex II
Explanation:
The electron transport chain refers to a group of electron transporters embedded in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors which undergo redox (reduction and oxidation) reactions. The energy released during the transfer of electrons is coupled to the transfer of protons (H+) from the mitochondrial matrix into the intermembrane space, generating an electrochemical gradient that is then used to synthesize ATP. Complex I and Complex II are membrane-bound complexes that act as mitochondrial redox carriers. Complex I is a proton pump that uses energy from the electron transfer chain to pump protons, while Complex II sends H+ onto Complex III in the form of the reduced ubiquinol. Complex I receives electrons from NADH and transfers them to ubiquinone, while Complex II directly receives the redox cofactor FADH2 that does not pass through Complex I.
Match the type of metamorphism to its cause. Impact ? Heat Contact ? Directed pressure Dynamic ? Meteorite Regional ? Surrounding pressure SUBMIT
Answer:
Contact Metamorphism - Heat
The heat is the main cause, cooling magma affects the rock adjacent to an intrusive body.
Dynamic Metamorphism - directed pressure
It takes place due to grinding two large blocks of rock in a fault zone which causes a directed pressure that leads to heat and the formation of these metamorphisms.
Regional - surrounding pressure
A heat and lithostatic pressure come from depth within the earth.
Impact - Meteorite
By collision of meteorite to earth very high amount of kinetic energy is converted instantaneously to heat and differential stress.

Some students looked at pond water with a microscope. They saw prokaryotic and eukaryotic
organisms. The diagram shows one of the many organisms they saw.
Which best explains what type of organism this is? LT
(2 Points)
Answer:
C. Eukaryotic because it has a nucleus
Explanation:
All living organism have been classified into a wide category called DOMAIN, which consists of Eukarya, Prokarya, and Archaea. Living organisms are classified into each of these domains mostly based on whether or not they possess NUCLEUS in their cells.
Domain Eukarya known as Eukaryotes are made up of organisms that possess a membrane-bound NUCLEUS in their cell. According to this question, some students looked at pond water with a microscope and saw both prokaryotic and eukaryotic organisms. The organism displayed in the attached image is EUKARYOTIC simply because it has a NUCLEUS.

What do coral reefs and estuaries have in common?
Answer: hewo, there! your answer is below
stuaries are areas of water and shoreline where rivers meet the ocean or another large body of water, such as one of the Great Lakes. Organisms that live in estuaries must be adapted to these dynamic environments, where there are variations in water chemistry including salinity, as well as physical changes like the rise and fall of tides. Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
Explanation: Here's some Info Below <3
shallow water, reef-building corals have a symbiotic relationship with photosynthetic algae called zooxanthellae, which live in their tissues. The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis. In return, the algae produce carbohydrates that the coral uses for food, as well as oxygen. The algae also help the coral remove waste. Since both partners benefit from association, this type of symbiosis is called mutualism.
Deep-sea corals live in much deeper or colder oceanic waters and lack zooxanthellae. Unlike their shallow water relatives, which rely heavily on photosynthesis to produce food, deep sea corals take in plankton and organic matter for much of their energy needs.

Explain how the lymphatic system is adapted for the transportation of the lymph
Answer:
The lymph capillaries feed into larger lymph vessels. The lymph vessels that receive lymph fluid from many capillaries are called collecting vessels. Semilunar valves work together with smooth muscle contractions and skeletal muscle pressure to slowly push the lymph fluid forward while the valves prevent backflow.

I did the science moon phases for this! I would explain if it showed the graph and everything.
Good luck with it!
The Moon's orbit, which completes one full spin in 27 days, 7 hours, and 43 minutes, is the source of this motion. It compels the Moon to move 12–13 degrees east every day. February 25, March 27, April 25, May 24 Thus option C is correct.
What is Full Moons?When the Moon fills the sky in a perfect circle, it is said to be full.
We can only view the portions of the Moon that are illuminated by other objects because the Moon doesn't create any visible light on its own.
This change causes Moonrise to occur every day around 50 minutes later and necessitates a slightly longer Earth rotation to bring the Moon into view.
Technically, the Moon's “fullness” lasts only a brief period of time.
Therefore, the Moon can appear to be full to the unaided eye for as long as three days.

Describe at least three large - scale detrimental consequences of rising temperatures
Answer:
En primer lugar hay que decir que en contra de lo que puedan pensar muchas personas, el aumento de las temperaturas es una realidad. De hecho, no hay más que ver algunos datos comparativos para darse cuenta, por ejemplo, de que la temperatura de los polos ha aumentado considerablemente en el último siglo.
En primer lugar y por encima de todo tenemos que tener muy claro que el hábitat está cambiando de una manera abismal por lo que la vida del ser humano en La Tierra cada vez es más complicada. Si a esto le unimos el hecho de que nosotros no somos el único ser vivo cuya vida se complica, podemos concluir que muchas especies no serán capaces de adaptarse a estos cambios por lo que morirán. Un cambio que se puede llevar consigo gran parte de las cosechas que existen a día de hoy.
Una serie de consecuencias que lejos de ser catastróficas son más que plausibles. Es cierto que del mismo modo que esta situación se puede dar, no es menos cierto que todavía hay opciones de revertir la situación. La pregunta, sin embargo, es saber si el ser humano está dispuesto a ello.
