What happens in the light reaction of photosynthesis?
What happens in the dark reaction of photosynthesis?
What five factors affect photosynthesis and its rate? How?
Answer:
1). Photosynthesis begins with light reactions. It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast.
2). The dark reactions of photosynthesis occur in the stroma of the chloroplast where they utilize the products of the light reaction. In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose.
3). The main factors affecting the rate of photosynthesis are light intensity, carbon dioxide concentration, and temperature.

Can you tell from this tree whether a C at position 15 evolved before or after a T at position 15? Explain your answer
The evolutionary tree is not observed here but it is possible to answer this question by observing which nucleotide is found in the root of the node. It indicates the first substitution.
What is an evolutionary tree?A phylogenetic evolutionary tree is a diagram used to show the evolution of a given taxonomic group (for example, a group of species).
It is possible to trace the evolution of a given taxon by tracing the nucleotide substitution observed from a common ancestor.
In an evolutionary tree, the root of the node is represented by the common ancestor and therefore the presence of a particular nucleotide (either T or C) in that position can be considered as the ancestral character.

What molecule do plants pull from the air that is used to make sugar?
A.Oxygen
B.Nitrogen
C.ATP
D.Carbon dioxide
Answer:
carbon dioxide is what the plants take from the air to make glucose or sugar
The molecules that the plants pull from the air that is used to make sugar are carbon dioxide. The correct option is D.
What is carbon dioxide?
Carbon dioxide is a gas that is present in the atmosphere at 0.03 %. This gas is a greenhouse gas. This gas warms the environment. The chemical formula of carbon dioxide is CO₂.
Carbon dioxide is released by animals as they respire. This is the gas they expelled out in respiration. But plants absorb this gas because plants perform photosynthesis and in photosynthesis, carbon dioxide is used.
This gas is pulled from the environment to perform photosynthesis by plants. Carbon dioxide reacts with water to form glucose.
The chemical reaction of photosynthesis

Where does the electron flow that we measure with dcpip originate.
The electron flow that we measure with the entire process originated from Photosystem II.
What are electrons?Electrons may be defined as the type of subatomic particles that are always revolving around the nucleus of each atom. These types of subatomic particles are negatively charged in nature. Electrons are discovered by J.J. Thomson.
Photosystem II (PSII) is a multi-component pigment-protein complex that is responsible for water splitting, oxygen evolution, and plastoquinone reduction. This is the initial protein complex in the light-dependent reactions of oxygenic photosynthesis.
It is frequently located in the thylakoid membrane of plants. It is the place through which the reaction of photosynthesis begins with the flow of electrons and involves the water-oxidizing complex.
Therefore, the electron flow that we measure with the entire process originated from Photosystem II.

Which two processes will be involved as this chick grows into a chicken?
A. Cell growth due to taking in nutrients
B. Cell division that involves meiosis
C. Cell division that involves mitosis
D. Cell growth due to fertilization
Answer:
Two processes that are involved as the chick grows into the chicken are -:
Cell growth due to taking in nutrients.Cell growth due to fertilization.Explanation:
Cell growth due to taking in nutrients -: Within the egg, Special temporary organs or embryonic membranes develop both to protect the embryo and to provide nutrition, breathing, and excretion for it. The yolk sac, amnion, and allantois contain these organs include the yolk sac, amnion, and allantois.The yolk sac provides the embryo with food. The amnium provides protection by enclosing the embryo. As a respiratory organ, the allantois collects minerals from the shell and treats waste. Until the moment of hatching, these temporary organs act inside the embryo.
Cell growth due to fertilization -: In the single cell produced by the union of two parental cells, the egg and sperm, the development of the chick starts in the process known as fertilization. Division of the cells stops as the egg is laid and cools. After the egg is laid, cooling the egg does not result in the embryo 's death after the egg is laid.Hence , the correct options are A and D.

Which of the following activities would NOT represent an anatomical study? *
~making a section through the heart to observe its interior
~drawing blood from recently fed laboratory animals at timed intervals to determine their blood sugar levels
~examining the surface of a bone
~viewing muscle tissue through a microscope
The activity that does not represent an anatomical study is 'drawing blood from recently fed laboratory animals at timed intervals to determine their blood sugar levels'.
Anatomy is a field of biology that studies the structure of organisms and their components. The study of human anatomy is fundamental in the field of Medicine.
Anatomy is split into two categories:
Macroscopic anatomy: the study of an animal's bodily components with unassisted vision is known as macroscopic anatomy, or gross anatomy. The branch of superficial anatomy is included in gross anatomy.Microscopic anatomy: entails the use of optical equipment to investigate the tissues of different structures, a process known as histology, as well as the study of cells.The activities mentioned in the question all represent anatomical study but the second one, because analyzing blood sugar levels has no relation to anatomical structures but the chemical composition of the blood.
On the other hand, making a section through the heart to observe its interior, or examining the surface of a bone are great examples of macroscopic anatomy, while viewing muscle tissue through a microscope represents microscopic anatomy.
In the attached image, it shows how macroscopic and microscopic anatomy complement one another.

if humans were wiped out and allowed room for a new dominant species, out of all animals listed which one would have the most potential to do so?
Answer:
the raven
Explanation:
octopus - intelligent but very antisocial with a short life span, meaning they most likely will not work with other octopuses to improve while also living in the ocean making it harder to build. (but could probably evolve to walk on land)
dolphin - smart but does not have thumbs to make tools and lives in the ocean meaning they have a disadvantage.
raven - intelligent, works with other ravens and sometimes even wolves, and has shown to make tools.
Answer:
The raven because it's ability to craft tools, social life involving hunting groups, intelligence, and wide variety of sounds (allowing potential language) give it the potential to evolve very well.
Explanation:
What is the source of all energy? What organisms transfer this energy into a usable form for all other organisms? Explain the percent of energy that is transferred to the different trophic levels. If all the energy is not being transferred where is it going? Be sure to use terms like metabolism, decomposers, producers, primary consumers, secondary consumers, and tertiary consumers.
Answer:
1- the sun
2-Plants performing photosynthesis convert carbon dioxide to organic carbon compounds using sunlight as a source of energy; these compounds go on to fuel nearly all other organisms in the ecosystem, from bacteria to animals.
3-The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
Explanation:
1-Energy is all around us and comes from many sources. One of the most important sources of energy is the sun. The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells.
