Answer: Yes.
Trees are producers
Explanation:
Trees are producers because they have the ability to produce organic materials like sugar.
Trees have green pigments called chlorophyii on their leaves, this pigment trap light energy from the sun and uses carbondioxide and water to photosynthesized in order to produce sugars. Trees undergo a process called photosynthesis which is a process where by green plants uses light energy from sunlight with water and carbondioxide to produce sugars.
Once trees produce sugars, other organism cannot synthesized their own food on their own, so they largely depend on trees for organic materials. Theses organisms are herbivores and sometimes omnivores.
Therefore, Trees are producers.

Describe what occurs between water molecules in hydrogen bonding. Draw a diagram, labeling the hydrogen bond.
Answer:
The molecules are attracted to their less negative side.
Explanation:
The Oxygen in the water molecule will share or the hydrogens lone atom leaving the hydrogen with a more positive charge like in the picture I've added. This happens with all water molecules leaving the oxygen with more electrons and ultimately the more negative side. And positive and negative forces attract, so the now "positive" hydrogens will bond with the now "negative" oxygens. They form bonds using polarity, and use a very strong dipole dipole effect.

One of the first explanations of evolution was put forth by a French biologist, Jean-Baptiste
Lamarck. He theorized that animals, in responding to different environments, adopted new
habits. Their new habits caused them to use some organs more and some organs less, which
resulted in the strengthening of the former and the weakening of the latter. New characters
thus acquired by organisms over the course of their lives were passed on to the next
generation. His theory proposed this process of use and disuse, repeated over many
generations, was how species evolved.
He was wrong. Why?
Answer:
Traits acquired during an organism's lifetime cannot be passed
Explanation:
The law of use and disuse of organs as postulated by Jean Lamarck was wrong due to the fact that environmentally acquired characters cannot be passed to offspring.
Changes to organisms that are not the level of the gene cannot be passed to the offspring. For example, a wrestler that got big muscles due to constant work out cannot pass big muscles to his offspring. The offspring will need to work out in order to have big muscles. This is because big muscles in the wrestler is environmentally acquired.
Only changes that happen to the genome of an organism (mutation) can be passed to offspring.
Was it beneficial or harmful for the Balanus barnacle to add the Chthamalus barnacle? Explain
Answer:
harmful. (more info below)
Explanation:
Balanus may compete with Chthamalus through crowding or smothering, but Chthamalus can inhabit higher tide levels than Balanus since it is more immune to desiccation. Lower on the sea, the barnacles of acorn combine with the Endoclades (Turfweed) assemblage, and are also abundant on the shells of acorn. To conclude, it was a bad idea is add the balanus barnacle to the Chthamalus barnacle becuase balanus barnacles can crowd Chthamalus barnacle.

Digestion is the process of breaking down large food molecules into smaller molecules that are ________ .
Enzymes help to break down food because they ________
chemical reactions.
If the temperature of an enzyme gets too high, the enzyme is ________ .
Answer:
1. Soluble
2. Catalyze
3. Denatured
Explanation:
1. We eat in order to obtain energy. However, this food is often in a complex state and needs to be broken down into its simplest form. The process of digestion ensures this occurs in living organisms. Digestion is the process of breaking down large food molecules into a much more simpler molecule that can be passed on to the blood stream for absorption by cells. These simpler molecules must be SOLUBLE in water for them to be transported into each cell via the bloodstream.
2. The breaking down of food molecules described above is facilitated by certain proteinous chemical agents called ENZYMES. Enzymes are biological catalysts i.e. they help speeden up the rate of biochemical reactions in living systems. In the case of digestion, specific enzymes chemically acts on specific food molecules. For example, amylase acts on carbohydrates, protease acts on proteins etc.
3. As stated above that enzymes are proteinous, it means they possess the characteristics of proteins. One of those characteristics is the ability to get denatured by increase in temperature. High temperature causes an enzyme to lose its specific 3D shape, affecting its functionality. Hence, the enzyme is said to be DENATURED.

Albinism is inherited as autosomal recessive trait. The frequency of the disease in the population equals to 1:20 000. Calculate frequency of heterozygotes in population.
Answer:
0.0139- frequency of heterozygotes in the population
Explanation:
Let q to the power of 2 represents the frequency of the homozygous recessive (aa) = 1/20000 = 0.00005
This, q = √q^2 = √0.00005 = 0.007
Since p + q = 1
p = 1 - 0.007 = 0.993
Using the formula: p^2 + 2pq + q^2
Where 2pq represents the frequency of the heterozygotes, thing we have
2 x 0.007 x 0.993
= 0.0139

When vinegar and baking soda react, the mixture becomes cold to the touch and a gas and a new liquid substance are formed. Which best describes what is occurring in the reaction?
Answer:
answer B The reaction is chemical and exothermic.
Explanation:
because on my quiz its b.
The described chemical interaction between vinegar and baking soda is an endothermic reaction since it involves the absorption of energy, which causes the mixture to become chilly. The correct option is A.
What is endothermic reaction?A chemical reaction that is endothermic is one that increases the system's enthalpy through a thermodynamic process. A system engages in this process by absorbing energy from the environment, primarily thermal energy.
As a result, an endothermic reaction causes the system's temperature to rise while the environment's temperature drops.
Bonds are typically formed during endothermic processes, which demand energy input. Entropy of the environment is reduced during endothermic reactions.
Endothermic reactions frequently entail physical rather than chemical changes. The potential energy of the products exceeds that of the reactants in an endothermic process.
Thus, the correct option is A.
