Answer: changes in climate
Change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).
What are Fossils?A fossil is defined as the preserved remains, impression, or trace of a once-living thing from a past geological age, including bones, shells, exoskeletons, fossilized traces of animals or microbes, amber, hair, petrified wood, and DNA. The totality of fossils is known as the fossil record.
There are five types of fossils which are as follows:
Body FossilsMolecular FossilsTrace FossilsCarbon FossilsPseudo fossilsThe fossil record shows that the types of living things on Earth changed over time which reveals the Earth's history.
Thus, change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).

How are the carbon and oxygen cycles interconnected?
A. The carbon dioxide produced during photosynthesis is used during respiration to produce oxygen.
B. The carbon on the surface of the Earth combines with oxygen in the air to form the water in the ocean.
C. The oxygen produced during photosynthesis is used during respiration to produce carbon dioxide.
D. The oxygen produced during photosynthesis becomes a component of water in the atmosphere.
Answer:
A.
Explanation:
Because carbon dioxide produce energy and releases oxygen
The oxygen and carbon cycles are interconnected as both produced or recycled by the living organisms as option C. The oxygen produced during photosynthesis is used during respiration to produce carbon dioxide.
Oxygen and carbon are moves between the atmosphere, biosphere, and lithosphere but the most important part is movement between the biosphere and atmosphere:
In the biosphere, carbon dioxide is used as a reactant to produce oxygen that moves to the atmosphere by the process called photosynthesis in plants.During cellular respiration atmospheric oxygen is used by the living organism to produce energy and releases carbon dioxide as a byproduct.On the basis of the given explanation, the correct answer would be - Option C.

Hope u guys have great day. ✌❤
Competition is defined as a biological interaction between or among the same or different organisms where organisms fight for resources. Competition explains this struggle. So, the correct option is D.
What is Competition?Competition is defined as an interaction between organisms or species in which both require a resource in limited supply that reduces the fitness of both organisms because the presence of one of the organisms will always limit the resource available to the other that reduces the quantity.
Competition is defined as a biological interaction between or among the same or different organisms where organisms fight for resources. Competition explains this struggle. Some example of competition is trees in the forest grow tall to compete for sunlight.

How may mRNA be modified before it leaves the nucleus?
Answer:
The pre-mRNA molecules undergo three main modifications. These modifications are 5' capping 3' polyadenylation and RNA splicing which occur in the nucleus before RNA is translated.
Explanation:
mRNA compares to the hereditary succession of quality, and is perused by a ribosome during the time spent combining a protein.
How mRNA can be modified?it should go through extra handling before it leaves the core. This might incorporate joining, altering, and polyadenylation. These cycles adjust the mRNA in different ways. Such alterations permit a solitary quality to be utilized to make more than one protein. Exons are segments of mRNA which become "communicated" or converted into a protein. They are the coding bits of a mRNA atom.

what is the function of photosystems
Answer:
Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes.
Explanation:
The main functions of a photosystem are: they are a functional unit of photosynthesis, and they trap or release light.
What is a photosystem?Plants, algae, and cyanobacteria all have thylakoid membranes that contain photosystems. These membranes are found in the cytoplasmic membrane of photosynthetic bacteria as well as the chloroplasts of plants, algae, and other vascular organisms. The PSI and PSII subtypes of photosystems exist.
The functional components of photosynthesis are called photosystem, and they are identified by specific pigment organization and association patterns.
Therefore, the photosystem is responsible for absorbing and transferring light energy, which entails transferring electrons. The thylakoid membranes contain photosystem in terms of physical location.

Answer:
Pulmonary blood vessel
Explanation:
The pulmonary blood vessel carries low oxygen blood to the lungs and brings high oxygen blood back to the heart.
More specifically, the pulmonary artery carries low-oxygen blood to the lung from the right ventricle of the heart. The blood becomes oxygenated in the lung and the oxygen-rich blood is taken back to the left atrium of the heart by the pulmonary vein.

An archer shot a 0.06 kg arrow at a target the arrow accelerated at 5,000 m/s squared to reach a speed of 50.0 m/s as it is left the bow.During this acceleration what was the net force to the nearest newton?
Answer:
the net force to the nearest newton is 300 N
Explanation:
The computation of the net force to the nearest newton is shown below:
According to the newton second law of motion, the force is proportional directly to the change rate in momentum
So,
Resulted force = mass × acceleration
F = 0.06 kg × 5,000 m/s
= 300 N
Hence, the net force to the nearest newton is 300 N
Answer:
300 N
