Ecosystem function is highly dependent on the flow of nutrients from one species to another in a cycle.
What is an ecosystem?An ecosystem refers to a biological community that typically consists of both living organisms (biotic factors) and the physical environment (abiotic factors) in which they interact.
What is a species?A species can be defined as a biological classification of related organisms with similar characteristics that are capable of breeding with one another in a cycle.
Generally, the proper functioning of an ecosystem is highly dependent on the flow of nutrients from one species to another in a cycle and as such determines their ability to survive.

You will use Punnett squares to predict the probability that two parents of your species will pass a particular trait to their
offspring. Each parent has two alleles for a particular gene, one on each homologous chromosome.
To prepare to make the Punnett squares, write down the genotypes of the parents for the three traits you'll be predicting.
The feature hair type is coded by a diallelic gene and expresses incomplete dominance. The cross of two wavy haired individuals will produce 25% curly-haired children, 50% wavy-haired and 25% straight-haired children.

Answer:
Millions of the centrioles migrating
Answer: No
Explanation: Plant cells have no centrioles, there would be no structures from which the fibers could radiate. In animal cells, asters form around the centrosomes during a mitotic division. Plant cells lack centrosomes, therefore, asters are not formed during mitosis in plants.
Which of the following statements best describe the way molecules move across a plasma membrane?
Based on scientific information, small, uncharged molecules can easily pass through the plasma membrane.
What is plasma membrane?Plasma membrane is also referred to as cell membrane and it can be defined as a semi-permeable cell organelle that is found in the body of all living organisms.
The main purpose of the plasma membrane is to prevent the passage of molecules into or out of the cells of all living organisms. Thus, it is semi-permeable and hydrophobic in nature and as such protects the cells depending on the size of molecules.
In conclusion, small, uncharged molecules can easily pass through the plasma membrane.

1. You have 4.0 g of NaCl. Calculate the number of moles of
NaCl this is (show your work).
Explanation:
i suppose this is chemistry..
no of moles = mass / molar mass
you are given the mass, 4.0g, you need to find the molar mass ( Mr ) of NaCl.
Mr = 23 + 35.5
Mr = 58.5
now that you know the Mr of Nacl, just use the formula:
n = m/mr
n= 4/ 58.5
n= 0.068376..
no of moles = 0.068 moles.
What is digestion ? Why do animals require a digestive system
Answer:
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.
Animals require a digestive system because they take food in the form that body cannot directly utilize. The food needs to be broken down into form that body can utilize. Therefore digestive system becomes very important animals. There are various other organisms apart from animals that possess a digestive system For example amoeba has food vacuole that helps in digestion.

how does the water cycle play a role in creating weather here on earth?
Answer:
The water cycle shows the continuous movement of water within the Earth and its atmosphere.
Explanation:
This is how the water cycle plays a role in creating the weather. It goes through many different processes that are complex. Liquid water goes through a stage and turns into vapor. Solids can melt and form into liquid.
Answer:
The water cycle absorbs and releases heat energy, which in turn, affects the weather patterns across the globe. When the water evaporates into the atmosphere, heat energy is absorbed. Once the water vapor condenses and falls back into the surface, heat is transferred from the atmosphere toward the ground.

. Why is water so important to cells?
Answer:
Water is an essential constituent of the protoplasm of living cells because it is directly involved in countless biochemical reactions like photosynthesis and respiration. Without it cells couldn't move waste and by-products, take in nutrients, perform intracelluar transportation, functioning and signalling.
How does
photosynthesis transfer
one form of energy to
another?
Answer:
During photosynthesis, the radiant energy is transformed to chemical energy stored in chemical bonds of glucose molecules the plant uses as food.
two examples of diffusion in plants and two in humans or animals.
Answer:
examples of diffusion in plants are:
The uptake of water and nutrients from the soil by the roots
The distribution of nutrients and water to all the parts of the plant
Diffusion of Carbon Dioxide into the leaf of the plants during photosynthesis
Release of oxygen out of the stomata of the leaf
Examples of diffusion in animals are:
Digested food molecules such as amino acids and glucose move down a concentration gradient from the intestine to the blood.
Waste products such as carbon dioxide or urea travel by diffusion from body cells into the bloodstream.
Oxygen moves from high concentration (in the air sac) to a lower concentration (in the blood). Carbon dioxide moves from high concentration (in the blood) to a lower concentration (in the air sac).

Colorblindness is an X-linked recessive trait. Samantha is colorblind and her husband, Rick, has normal vision. What is the probability that they will have a colorblind son?
Considering the whole progeny, there are 50% of probabilities of having a colorblind son. Considering only boys, there are 100% chances of having a colorblind son.
What is color blindness?Color-blindness is a disfunction characterized by an alteration in color perception.
This alteration might affect perception from only partial confusion and difficulties in distinguishing some tones of green and red, up to no chromatic distinction.
Color-blindness is an X-linked condition.
Women that are h0m0zyg0us recessive will be completely color-blinded (X⁺X⁺), Heter0zyg0us woman has partial color-blindness (X⁺X⁻). Men are or are not color-blinded (X⁺Y or X⁻Y).Available datacolor-blindness is an X-linked recessive condition X⁻ represents the X chromosome carrying the color blindness allele. The allele for color blindness is recessive to the normal form of the gene, X ⁺.Samantha is colorblind. Rick has normal vision.⇒ If Samantha is color-blind, then her genotype is X⁻X⁻.
⇒ If Rick has normal vision, then his genotype is X⁺Y.
Cross: Samantha and Rick

Which of the following methods can be used to determine the relative age of rock and strata? Select all that apply.
Oceanography
Stratigraphy
Blostratigraphy
Archeology
Paleontology
Answer:
Stratigraphy and Biostratigraphy.
Explanation:
Relative dating is a method of determination of age, in which one object or organism is compared with the other object or organism found in the heap of strata. It is a method for determining the relative order of the past events, without stating the absolute age.
Stratigraphy is a branch of geology that studies the relative position of the sediments and rocks in the strata with respect to the geological timescale. Biostratigraphy is the branch of stratigraphy which deals with the relative aging of fossils with respect to the strata in which these are found defining a particular period of geological time scale.
