Answer:
First two rings are thicker while the last two rings are thinner.
Explanation:
Due to the first two years of optimal growing conditions received by the tree, the width of trunk of the tree is thicker but due to drought conditions experienced by the tree during the most recent two years, there is very little increase occur in the width of the trunk because the tree is in stress condition and for that reason the ring of trunk is thinner as compared to first two years.

Which structure is found only in plant cells and functions in the process of photosynthesis?
Answer:
Chloroplasts are specialized organelles found only in plants and some types of algae. These organelles carry out the process of photosynthesis, which turns water, carbon dioxide, and light energy into nutrients from which the plant can obtain energy. There can be over one hundred chloroplasts in certain plant cells.

From the examples below, select the examples of cells or organisms responding to stimuli in order to maintain homeostasis.
Example of cells or organisms responding to stimuli in order to maintain homeostasis
A unicellular organism beating microscopic hairs to escape a chemical pollutant in its environmentA plant bending toward a light sourceAnts moving within their mounds depending on the time of dayIguanas laying in the sunlight if their body temperature is lowA person shivering when their body temperature is low.What is homeostasis?Homeostasis is the process by which the body maintains a fairly constant environment at all times.
Homeostasis is important to organisms because the cells of the body can only perform their metabolic functions efficiently within certain physiological conditions.
Example of cells or organisms responding to stimuli in order to maintain homeostasis include the following:
A unicellular organism beating microscopic hairs to escape a chemical pollutant in its environment so that the internalenvironment is not adversely affected by the pollution in the external environment A plant bending toward a light source in order to receive more light required for growth and production of food. Ants moving within their mounds depending on the time of day in order maintain their body temperatures within the optimum range requiredfor continuous body functions.Iguanas laying in the sunlight if their body temperature is low in order maintain their body temperatures within the optimum range requiredfor continuous body functionsA person shivering when their body temperature is low in order maintain their body temperatures within the optimum range requiredfor continuous body functions.In conclusion, homeostasis helps organisms respond and adapt to changes in their environment.

Blood from the brain drains into a large dorsal sinus called the ___________ ___________________. Blood
then travels through several other sinuses that join to form the ___________ ___________________, which
leave the skull and enter the neck.
Blood from the brain drains into a large dorsal sinus called the dural venous sinuses. Blood then travels through several other sinuses that join to form the plexus which leaves the skull and enter the neck.
The cranial cavity's venous blood is drained by a set of blood vessels known as the dural venous sinuses. In order to sustain systemic circulation, it all returns deoxygenated blood from the head to the heart.
Between the two layers of the dura are endothelial-lined sinuses known as the dural venous sinuses (DVSs) (meningeal and endosteal layers). They bring venous blood to the internal jugular veins at the base of the skull from the brain, meninges, and calvaria. There are five unpaired dural sinuses (superior & inferior sagittal, straight, occipital, and intercavernous) and seven paired dural sinuses (transverse, cavernous, greater & lesser petrosal, sphenoparietal, sigmoid, and basilar).

the complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.
Explanation:
Explanation:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
a. If your body does not take in protein, but only carbohydrates and lipids,
what atoms will it be missing? Hint: There are two, and you can figure this
out by comparing the structures of the monomers for proteins and
carbohydrates as well as the basic structure of lipids.
Answer:
The main two atoms missing when you do not eat protein is Nitrogen and Sulfur. Lipidsand carbohydrates contain Carbon, Hydrogen and Oxygen. Although protein does containCarbon, lipids and carbs do not contain Nitrogen and Sulfur. The main two atoms missing when you do not eat protein is Nitrogen and Sulfur

Explanation:
Describe the levels of cellular organization in an animal, and explain how organs work together as a system.
Answer:
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.

mRNA sequence is mutated from CCC GGG to CCG GGG. What type of mutation occurred? Select all that apply.
point mutation
silent mutation
indel
insertion
deletion
missense
nonsense mutation
If mRNA sequence is mutated from CCC GGG to CCG GGG, the mutation will be point and silent.
Point Mutation:
It is type of mutation in which only one nitrogenous base is exchanged with another one. This can be silent if the codon resulting is coding for same amino acid.
Here, CCC codon mutate to CCG, the mutation occur at a single base, hence it is point mutation.
Since, both Codons code for the proline, hence mutation is a silent mutation.
Therefore, if mRNA sequence is mutated from CCC GGG to CCG GGG, the mutation will be point and silent.

Tropical rainforests are viewed as rich in biomass productivity. Currently much of the trees in tropical forests are being cut down for establishing cattle ranches.
How thick or deep is the tropical forest O and A soil horizons?
*Give your best explanation of what natural processes are taking place to explain why this is the case* (the part I need help with mainly)
The tropical A Horizon has a intensity of 2-5cm thick, some distance much less than that of the A Horizon of temperate soils. In different soil types, the following layer, or B Horizon, consists normally of rocks.
Since there are few rocks withinside the Amazon, the B Horizon is typically tender sedimentary clay. This layer can also additionally amplify to 4km beneath the floor.The number one soil orders located in tropical rainforests are Oxisols and Ultisols, that are soils wealthy in iron and aluminum oxides (pink color) however with low herbal fertility.
The A-horizon is typically known as the topsoil, and usually tiers from 8-20 cm in thickness. It is a mineral horizon that shaped on the floor or beneath an O-horizon, and is characterised through an accumulation of humified natural rely in detail combined with the mineral fraction.
