Answer:
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

List the 3 names of the 3 inputs of photosynthesis using the chemical formulas
6CO2 + 6H2O → C6H12O6 + 6O2
Explanation:
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

The strangler fig’s roots grow up and down the host tree, it latches onto. These roots eventually grow high enough to reach the sunlight in the cloud forest. Typically, after this happens the host tree eventually dies, leaving a hollowed-out center wrapped in large roots. What type of tropism is responsible for the hollowed-out tree? Explain your answer.
Answer:the relationship between host tree and strangler fig may be more mutually beneficial than previously thought, in a symbiosis where the host provides a structure to support the strangler fig's establishment in the well-lit canopy, and the strangler fig helps to support its host during storms
The aerial roots of strangler figs may attach to surrounding vegetation on the ground, stabilising the host plant and making it less likely to become uprooted. The leaves of the fig may also help shield from wind by closing up the forest canopy. Geotropism

Using satellite tracking, scientists know that whales respond to the seasonal changes of winter by travelling to the warmer waters of Florida to give birth to their calves. Option 4 is correct.
What is satellite tracking?The object in the space which collects information or is a part of communication system. Tracking or watching artificial satellites is called as satellite tracking. People doing this work are called as satellite trackers or satellite watchers, observers or spotters.
Satellites are used for observation of the earth, for communication as radio telecommunication, for navigation purpose. They are also used as telescope and for experimental purpose.
It also plays significant role in tracking of migratory animals such as whales. Tracking devices are attached to the back of whale through the suction cups, which record depth, water, temperature, and underwater sounds.

why do olws turn their heads around
Answer:Because they can't see
Explanation:Owls have tubular rather than round-shaped eyes, so they aren't able to move them around much. That's why they rotate their heads – so they can see. ... As it turns out, owls have uniquely constructed necks and an arterial system that feeds blood to the brain even while they are twisting their necks to rotate their heads.

The science club at Tracy's school is researching how temperature affects fish reproduction. They conducted a study to find out if raising the water temperature would decrease the number of bass eggs that hatched.
They gathered bass eggs from a local lake. Half of the aquariums were kept at room temerpature, and the other half were placed in a sunny window.
What is the independent (test) variable from this experiment?
The size of the lake.
The number of bass eggs that hatch.
The temperature of the water.
The number of aquariums.
Answer:
The temperature of the water.
Explanation:
The independent variable is the thing you are changing in order to observe an outcome. The dependent variable is the outcome (the number of bass eggs that hatch).
Explain Mendel’s laws in genetic terms, that is, in terms of chromosomes, genes, and alleles.
Mendel's First Lawstates that for the pair of alleles an individual has of some gene (or at some genetic locus), one is a copy of a randomly chosen one in the father of the individual, and the other if a copy of a randomly chosen one in the mother, and that a randomly
A parent may have two distinct alleles for a certain gene, each on one copy of a given chromosome. Mendel's second law, the law of segregation, states that these two alleles will be separated from each other during meiosis.

Which of these organisms is not a chordate? earthworm snake sea squirt human
Answer:
Humans
Explanation:
Humans are not chordates because humans do not have a tail. Vertebrates do not have a notochord at any point in their development; instead, they have a vertebral column.
The organism that is not a chordate is the earthworm.
What are chordates?Chordates are a group of animals that possess four distinctive anatomical features at some point during their life cycle: a notochord, dorsal nerve cord, pharyngeal slits, and a post-tail. These features set chordates apart from other animal groups and have been critical in their evolutionary success.
Chordates include a wide variety of animals, ranging from fish, amphibians, and reptiles to birds and mammals, including humans. Chordates are found in aquatic environments such as oceans, rivers, and lakes, as well as on land, and play a critical role in many ecosystems as both predator and prey.
