which type of organism can use photosynthesis to make food
Answer:Plants
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 1). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).
Explanation:
Answer:
All plants with green leaves, from the tiniest mosses to towering fir trees, synthesize, or create, their own food through photosynthesis. Algae, phytoplankton, and some bacteria also perform photosynthesis. Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis.

What are the 4 steps of protein synthesis?
Answer:
In every eukaryotic cell, such as plants and animals, there is DNA in the nucleus. The nucleus is an area surrounded by a membrane (nuclear membrane) which has some pores for materials to enter and exit, but these are controlled.
The DNA is the cell's instructions, it is a series of code that can be transcribed and translated to make proteins. As in the image below DNA is a series of bases attached to a sugar phosphate backbone and bonded to another base pair to made a ladder, this ladder is twisted making the shaped called a double helix . There are four base pairs: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).
The bases have bases they bond to making complementary base pairs , A and T bond together while the C and G bond together. on each strand of DNA one end is labelled 5' (read as 5 prime) and other end is the 3'. The 5' end base pairs of one strand are always attached to the 3' end of the complementary strand. Labelling the ends helps us to describe in which direction DNA is read.
Since the DNA cannot leave the nucleus , copies of the section needed to make the protein are made, this is called transcription.
This done by first opening the double helix with an enzyme called DNA Helicase. Another enzyme called RNA polymerase will match new bases to the original DNA attaching them in a long strand of mRNA. When the enzyme reaches the end the strand will be removed and the DNA can close.

The molecule is illustrated in figure ________.
A) is a saturated fatty acid B) stores genetic information
C) will be liquid at room temperature D) is a carbohydrate
The molecule is illustrated in the figure is an unsaturated fatty acid. These molecules are liquid at room temperature (Option C). It is for that reason that unsaturated fatty acids are called oils.
The unsaturated fatty acids are liquid at room temperature, thereby they are known as oils (they are mainly found in plant fats).
The unsaturated fatty acids have one or more double bonds of carbon to carbon atoms.
Conversely, saturated fatty acids are solid at this temperature and do not have double bonds (they are mainly found in animal fats).

Explanation:
do you think carbon sinks can ever completely reverse global warming, why or why not?
Answer:
Explanation:
Framed in this way, the problem of climate change becomes not one of simply producing greenhouse gas, but how quickly we do so when compared with the Earth’s natural ability to soak it up again. And it makes that natural ability – the continuing capacity of forests and oceans to act as carbon sinks – as significant a factor in deciding the likely course of rising temperatures in the near future as intended controls on our greenhouse gas emissions. Yet many people are unaware of this side of the carbon balancing equation. And if they are, they take it for granted – they expect that forests and oceans and other carbon sinks will continue to act as our environmental get-out-of-jail-free card.
Or, more accurately, our go-to-jail-slightly-slower card. While sinks have managed to grab about half the carbon released as human pollution in recent centuries, the rest steadily accumulates in the atmosphere. The forests and oceans simply can’t suck it in fast enough. At the last count, atmospheric levels of carbon dioxide registered almost 412 parts per million (ppm) and rising. That’s a 47 per cent jump since the beginning of the industrial age, when the concentration was near 280 ppm, and an 11 per cent rise since just 2000, when it was near 370 ppm. Without our natural carbon sinks working to buffer the impact, that figure would probably be closer to 700ppm today.
It makes sense, then, that the future behavior of Earth’s massive carbon sinks – and specifically the question of whether they will continue to bail us out by taking in carbon dioxide – is a key topic of research for scientists. How will tropical forests respond to warmer temperatures? Will ocean currents continue to carry carbon to the depths? What happens to the pace of climate change if the carbon-catching capacity of these sinks weakens?

1. In human beings, a downward-pointed frontal hairline ("widow's peak") is a heritable trait. A
person with a widow's peak always has at least one parent who also has this trait, whereas
people with a straight frontal hairline may occur in families in which one or even both parents
have widow's peaks. When both parents have a straight frontal hairline, all children also have
a straight hairline. Using A and a to symbolize alleles for this trait, what is the genotype of an
individual without a widow's peak? (Show your work)
The genotype of an individual without a widow's peak would be aa.
A person with widow's peak has. at least a parent with the trait. When both parents have a straight frontal hairline, all the children also have a straight frontal hairline.The above features are indications that widow's peak is a dominant trait.
Since A and a are used to represent the alleles, AA or Aa will be the genotype of individuals with widow's peak while only aa will be the genotype of individuals with straight frontal hairlines.
In other words, individuals without a widow's peak will have aa as genotypes.

Which side is hypertonic ? A or B ?
Which side will gain water
What is c ?
Answer:
1-b
2-b
3-phospholipid bilayer
B side is hypertonic. It will gain water. C is Phospholipid layer.
What is Hypotonic Solution?
A hypotonic solution is a type of solution that has a lower osmotic pressure than any other solution to which it is compared. It is a solution in which a small amount of solute passes across a semipermeable membrane compared to the amount of solute in the other solution.
If the solute concentration outside the cell is lower than inside the cell, these solutes cannot cross the membrane, so the solution is hypotonic to the cell.
The cell membrane consists of a phospholipid bilayer containing embedded proteins present between these two solutions where a hypotonic solution has a relatively low concentration of solutes.
Thus, B side is hypertonic. It will gain water. C is Phospholipid layer.

What is the difference between diffusion and osmosis?

What characteristics of a molecule affect whether it can pass through the plasma membrane of a cell?
In the simulation, when protein molecules were evenly distributed on both sides of the membrane, was the solution isotonic, hypertonic, or hypotonic?
Which direction was water flowing?
In the simulation, when protein molecules were more highly concentrated on the inside of the cell than outside of the cell, was the solution isotonic, hypertonic, or hypotonic?
Which direction was water flowing?
Why is it important that the plasma membrane surrounding cells is semipermeable?
What would happen if it were not semipermeable?
1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and from movement of water molecules along the concentration gradient.

Your answers may vary, but these sample answers are a model to follow.
Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.
A semipermeable membrane allows some substances to pass through it.
The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.
The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.
In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.
The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.
In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.
A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.
If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.
Diffusion and osmosis has one difference which is the presence of semi-permeable membrane.
What is the difference between diffusion and osmosis?Diffusion is the movement of particles from an area of higher concentration to one of lower concentration while on the other hand, osmosis is the movement of particles from a semipermeable membrane.
Cell membrane is selectively permeable which only allows some molecules inside the cell because of its structure. So we can conclude that diffusion and osmosis has one difference which is the presence of semi-permeable membrane.
When protein molecules were evenly distributed on both sides of the membrane, the solution will be isotonic because of the same quantity on both sided. There is no movement of water in the body.
When protein molecules were more highly concentrated on the inside of the cell than outside of the cell, the solution will be hypotonic because of the less amount of water in the body.

Choose which assumption must be made in order for this estimate of broad-sense heritability to be correct.
a. The phenotypic variance of the genetically identical plants is the same as the genetically variable population.
b. The genetic variance component is strictly the result of additive genetic variance.
c. The environmental variance of the genetically identical plants is the same as that of the genetically variable population.
d. There is no phenotypic variance associated with the environment.
The assumption 'environmental variance of the genetically identical plants is the same as that of the genetically variable population' is CORRECT. It is used to estimate the variation due to genetic factors.
Heritability (h2) refers to the proportion of the variability of a given phenotypic trait due to genetic factors.
Broad-sense heritability is affected by genetic and environmental factors.
Broad-sense heritability can be estimated as H² = VG/VP, where VG and VP represent genetic variability and phenotypic variability, respectively.
