Answer:
Describe the two eukaryotic animal organelles that have roles similar to the organs of the human digestive system
→Two eukaryotic animal cell organelles that have roles similar to the organs of the human digestive system are lysosome and mitochondria.Describe how proteins are made packaged and transported within the cell
→Vesicles transport the proteins from the ribosomes to the Golgi apparatus, a.k.a Golgi complex, where they are packaged into new vesicles. The vesicles migrate to the membrane and release their protein to the outside of the cell. Lysosomes digest and recycle the waste materials for reuse by the cell.Answer:

Why is plastic a non-biodegradable and nonpoint source of pollution?
Plastic is a non-biodegradable and non-point source of pollution because it cannot be broken down into degradable materials by micro-organisms. It comes from man-made substances and industries therefore, it is non-point pollutant.
What is Plastic?Plastic is a non-biodegradable and non-point pollutant. Because, the enzymes in the microorganisms cannot break down the waste into bio-degradable materials as microbes cannot recognize the bonds that hold these polymers together. Eventually, the polymers in plastic may break down, perhaps after hundreds of years. But after a long time, the damage is already done to the environment.
Nonpoint source of pollution comes from oil, pet waste, herbicide, bacteria, sediment, and any other contaminant that ends up on the ground naturally or from human activity.

Atoms whose outer electron shells contain eight electrons tend to do what
Answer:
Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing. They do not react because they have no electronegativity and no "extra" electrons
Explanation:
Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing.
What is electronic configuration of carbon?Carbon atomic number is 6. Its electronic configuration is 1s2 2s2 2p2. As you can see from the electronic configuration the inner shell has 2 electrons and the outer shell with principal quantum number 2 has 4 electrons.
An atom is made up of electrons, protons and neutrons. Both protons and neutrons are located in the nucleus of the atom, while electrons are in the shell/s. The shell of an atom is the orbit on which the electrons revolve around the nucleus. The number of shells in an atom extends from the first, n =1, to infinity, n = ∞, depending on the number of electrons in the given atom.
The first shell, n =1, is the ground state and can only contain a maximum of 2 electrons. The inner shell contains two electrons and the outer shell contains four electrons.
Therefore, Atoms with a full valence shell are non reactive. Most shells have room for 8 electrons, so these atoms described are most likely noble gases. The answer is more or less nothing.

2. Explain why glucose continues to enter a cell, even when the concentration inside the cell might be higher than outside.
Answer:
Both diffusion and facilitated diffusion are driven by the potential energy differences of a concentration gradient. Glucose enters most cells by facilitated diffusion. ... Na+ is maintained at low concentrations inside the cell and K+ is at higher concentrations. The reverse is the case on the outside of the cell
Glucose continues to enter a cell, even when the concentration inside the
cell might be higher than outside as a result of the process known as active
transport.
Active transport involves the movement of molecules through a
cell membrane against the concentration gradient. Examples include:
Antiport Pumps.Symport Pumps.This type of transport requires the use of energy such as ATP to move the
glucose molecules into the cell.

Identify organelles in a plant cell.
The organelles in the plant cell that are shown in the image are: A: Chloroplast, B: Vacuole, C: Cell wall and D: Endoplasmic reticulum.
A: Chloroplast - This organelle is responsible for photosynthesis, the process by which plants convert sunlight into energy and produce glucose. Chloroplasts contain chlorophyll, a pigment that captures light energy.
B: Vacuole - The vacuole is a membrane-bound sac filled with fluid, primarily containing water and various dissolved substances. It plays a role in storing nutrients, waste products, and maintaining turgor pressure in plant cells.
C: Cell Wall - The cell wall is a rigid outer layer found in plant cells, bacteria, fungi, and some protists. It provides structural support and protection for the cell, helping maintain its shape and integrity.
D: Endoplasmic Reticulum (ER) - This organelle is involved in the synthesis, folding, modification, and transport of proteins and lipids. It can be rough (with ribosomes on its surface) or smooth (lacking ribosomes). The rough ER is involved in protein synthesis and modification.

What is meant by a phenotype ratio in a Punnett square? (1 point)
A. the fraction of possible offspring that can be observed to have a trait
B. the number of genes that are possible in offspring
C. the number of alleles in possible offspring
D. the fraction of possible offspring that contain a certain allele in their genes
Given the nature of a punnet square, we can conclude that the ratio in question refers to the combination of genotypes present in the square.
A punnet square is a diagram used to attempt to predict the genetic composition for the offspring of certain parents, that is the genotype for this specific cross. This is done by creating a square in the form of a grid and placing the genotypes of the parents on the outside of this then crossing them along the inside.
This diagram provides us with the probability of each genotype outcome. This is known as the phenotype ratio. The phenotypic ratio is the amount of times a specific outcome, such as a certain pair of alleles appears in the predicted genotypes of any of the offspring pertaining to this cross.
