Answer:
1.) The two gametes found in humans are the sperm and the ova.
2.) Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).
3.) Because the alleles that the mother and the father carry are mixed together in the offspring.
4.) Because it only introduces genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.

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.
Answers
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.

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?
Answers
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

Sea otters regulate the presence of the sea urchins and thus, kelp is regulated for all organisms in the ecosystem. They help to keep enough kelp for other wildlife to feed on. Also, due to their ability to absorb carbon dioxide, the kelp aid in mitigating climatic change and also reduce erosion by reducing the speed of water at the coast.However, if there were too many sea urchins and no sea otter to regulate their production, the kelp would reduce and thus with no food in the ecosystem, it would collapse. As a result, the sea otter protects the kelp forests by checking the local sea urchin population. The sea otter is an example of a
Answers
Answer:
keystone species
Explanation:
The sea otter is an example of a keystone species in the scenario.
A keystone species is an organism that has a significant influence on the functioning of the entire ecosystem. Without this species, the ecosystem would either cease to exist in total or entirely different in structure. In other words, a keystone species is a fastener that holds the ecosystem together.
In this case, the sea otter indirectly regulates kelp for all organisms in the ecosystem by directly regulating the presence of sea urchins. Without kelps, several ecosystem functions such as climate change mitigation and erosion reduction would cease. Thus, the sea otter is playing a significant role as a keystone species.

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.

what is the function of photosystems
Answers
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.

How may mRNA be modified before it leaves the nucleus?
Answers
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.
