Which is abiotic?
tree sap
O insect
O sunlight
O tree stump
Answer:
Sunlight is abiotic. Abiotic is a non living thing
Sunlight is an abiotic factor. Therefore, the correct statement is option C.
What do abiotic elements consist of?Sunlight is an inanimate element of the environment, making it an abiotic one. Insects and tree sap are both living things, and a tree stump is a decomposing piece of the environment that was once alive.
Abiotic elements are the ecosystem's non-living parts. They include natural elements including sunshine, water, air, temperature, soil, and minerals as well as physical and chemical elements. In contrast, biotic factors include live species, including plants, animals, fungi, and bacteria.
Sunlight is a crucial abiotic component of ecosystems because it fuels photosynthesis and influences the development and behavior of living things. It also affects weather patterns and climate, which may have a big influence on ecosystems.
Therefore, sunlight is an abiotic factor including natural elements including sunshine, water, air, temperature, soil, and minerals as well as physical and chemical elements.

what are the factors that make the planet habitable
Answer:
Safe distance (like the earth) from the sun, starts surrounding the planet have to be stable, should not have a very low mass.
It must rotate on its axis and revolve.
It should have a molten core.
It should hold an atmosphere.
The planet (earth ) is habitable based on these factors :
Temperature Right chemical ( like water and oxygen )protection from solar radiationdistance from the sunThe planet ( earth ) is habitable because of some certain factors that cannot be found on other planets . such as The temperature of the planet ( earth ) is on an average of 58.62°F. which is the right temperature for human and plant habitation.
The presence of freshwater and oxygen in the atmosphere makes the planet habitable and also other necessary chemicals
The magnetic field of the Earth protects the Earth from high levels of solar radiation and this makes the earth safe and habitable for humans.
The distance of the earth from the sun also makes it possible for life to exist on planet earth
Hence we can conclude that the factors that make the planet habitable are :Temperature , Right chemical ( like water and oxygen ), protection from solar radiation, distance from the sun

Which statement best explains why BaCl2 is an ionic compound?
O A. BaCl, has a net charge of -2.
O B. The neutral atom Ba gains 2 electrons.
O C. BaCl, has a net charge of +2.
OD. The neutral atom Cl gains 1 electron.
Answer:
D. The neutral atom Cl gains 1 electron.
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Barium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.89. There is large difference is present. That's why two valence electron from barium is transfer to the chlorine. Barium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations. There are two valence electron lost by barium while chlorine required one electron to complete the octet thus two chlorine atoms are bonded with one barium atom. Each atom of chlorine carry -1 charge while one barium atom have +2 charge.

How does fossil evidence determine the relationships of whale ancestors and their descendants?
Similarities in the bone structure, the genetic composition, chemistry of the teeth etc
Explanation;Fossils are the trace or remains of an organism that lived long ago. Fossils provides a lot of evidence concerning the ancestors of whales.Fossil evidence shows that a land mammal the lived between 50 million and 70 million years ago. It is thought that whales evolved from these ocean-dwelling mammals.Whales Descended From Tiny Deer-like Ancestors. Scientists found that whales are mammals whose ancestors walked on land.The structures of the bones and chemistry of the teeth of a close relatives of whales such as Indohyus,indicates that they spent most of their time in water.Answer: If the fossil evidence determine the relationships of whale ancestors and their descendants, then they can see what are the remain of the fossils are the trace or remains of an organism that lived long ago.
Which of the following ways are leftover neurotransmitters cleaned up if they
have not been accepted by the postsynaptic neuron?
Pick 2
the neurotransmitters are broken down in the synapse
the postsynaptic neuron absorbs the neurotransmitters
The presynaptic neuron absorbs the neurotransmitters
the neurotransmitters are built up to create a new neuron
Answer:
The correct answer is -
the neurotransmitters are broken down in the synapse
The presynaptic neuron absorbs the neurotransmitters
Explanation:
The termination of the neurotransmitters is essential as if they can cause harm by continuing the stimulus effect on the muscles or cells. To clean up these neurotransmitters there are two ways- Degradation of neurotransmitters with the help of enzymes in the synapses or synaptic cleft and the presynaptic neurons absorbs or suck up neurotransmitters. The neuron (presynaptic neuron) is that releases the neurotransmitter like dopamine, serotonin, is the one that re-uptake it.
This reuptake is done by transporter proteins that are are symporters in nature as these proteins pump neurotransmitters as well as ions back into the neuron.

Often, the shape or structure of a cell is related to its_________
Answer:
Cells are limited by their surface area to volume ratio and they come in many different shapes. A cell's function is determined, in part, by its shape.
mark me as brainliest if u found it helpful
Answer:
Function
Explanation:
The shape of the cell, the organelles within it as well as how many of those organelles are present play a huge role in the cells function.
For example, muscles cells will have lots of mitochondria that are used for ATP production, needed in movement.
Lung cells will have ridges or groves in them that increase the cells surface area that make them much more effective at the diffusion of oxygen and carbon dioxide when breathing.

Is this Red blood cell in a Hypotonic, Isotonic, or
Hypertonic solution?
Explanation:
It is hypertonic . Hope it will help you!
Answer:
[tex]\boxed {\tt Hypertonic}[/tex]
Explanation:
The H₂O, or water is exiting the cell, and the result is shriveled up red blood cells.
In a hypertonic solution, there is a greater concentration of solute outside the cell and a greater concentration of water inside the cell.
The water will diffuse through osmosis from high to low concentration, so the water moves out of the cell.
Therefore, this is a hypertonic solution.

Describe what is happening with light and matter in photosystem II and Photosystem I.
Answer:
Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the high energy carrier NADPH.
It captures photons and uses the energy to extract electrons from water molecules. These electrons are used in several ways. First, when the electrons are removed, the water molecule is broken into oxygen gas, which bubbles away, and hydrogen ions, which are used to power ATP synthesis.
