Answer:
Look down!! ;)
Explanation:
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.

A _______________ from the sun hits chlorophyll and excites an electron, known as __________________________________.
Answers
Answer:
Photon, light dependent reaction of photosynthesis
Explanation:
Photosynthesis is the process by which green plants make their own food in the presence of sunlight and water.
There are two steps of Photosynthesis that include light dependent reaction and light-independent reaction.
In light dependent reaction, a photon from the sun is absorbed by the green pigment in leaves called chlorophyll that allow the electron to excite from ground energy level to high energy level. It converts the solar energy into chemical energy and called light dependent reaction of photosynthesis.
Hence, the correct answer is "Photon, light dependent reaction of photosynthesis".

Summarize cell division in prokaryotes
Answers
According to the research, the correct answer is that unicellular living beings like prokaryotes have their cell division by binary fission, forming two identical individuals (daughter cells).
What is binary fission?It refers to the process of cell division where first the deoxyribonucleic acid (DNA) is duplicated and then cytonesis occurs, which involves the separation of the cytoplasm.
In this sense, it gives rise to two daughter cells with identical genetic material, this is the reproduction method shared by certain yeasts, algae, bacteria and other prokaryotic organisms.
Therefore, we can conclude that the cell division mechanism of prokaryotes is through binary fission where two daughter cells arise.

A student states that petrification occurs when pore spaces in an organism's remains are filled with minerals that precipitate out of solution. What is wrong with this statement?
A.
Permineralization occurs when pore spaces in an organism's remains are filled with minerals that precipitate out of solution.
B.
Petrification occurs when once-living tissues are replaced by minerals, preserving the organism's structure.
C.
Both A and B describe errors in the statement.
D.
Nothing, this statement is correct as is.
Answers
Answer:
C. Both A and B describe errors in the statement.
Explanation:
In fossilization i.e formation of fossils, two terms are used as follows: permineralization and petrification.
- Permineralization is a process whereby the pore spaces of an organism's remains are filled with mineral matter that precipitates from lake and ocean solutions.
- On the contrary, petrifaction or petrification is the process whereby a once-living tissue (matter) are REPLACED by minerals, hence, preserving the organism's structure by turning it into a stone (petros).
According to this question, the student mixed up their definitions by giving the definition of permineralization instead, however, options A and B have described the errors associated with the statement.
If the forces acting on two objects are the same, which object has greater acceleration? An object that is 200 kg or an object that is 400 kg? Text to speech
Answers
Answer:
Object with 200kg
Explanation:
Newton's second law of motion depicts how the acceleration of an object depends on the force (F) and mass of the object (m). This law can be represented by the mathematical equation: F = ma
However, the acceleration of the object is inversely proportional to the mass i.e. a = F/m. This means that an increase in the mass of an object causes a decrease in acceleration of the object and vice versa.
According to this question, If the forces acting on two objects are the same, an object that is 200 kg will have a greater acceleration than an object that is 400 kg. Note: the higher mass the mass, the lower the acceleration and the lower the mass, the higher the acceleration.

If leaf color change is related to temperature, then exposing plants to low temperatures will result in changes in leaf color:
Independent: _________
Dependent: __________
Other variable(s): ________
Answers
Answer:
If leaf color change is related to temperature, then exposing plants to low temperatures will result in changes in leaf color:
Independent: temperature.
Dependent: leaf color.
Other variable(s): According to the information, there are no other variables.
Explanation:
When formulating a hypothesis, it is inevitable that the presence of variables on which the hypothesis is formed is established. The hypothesis raised is the effect of temperature on the color change of the leaf of a plant.
The independent variable, used in research work, is an element that does not depend on other variables but can influence the behavior of the dependent variable. In this case, the independent variable is the temperature. In addition, the independent variable can be managed to observe its effect on other variables.
An dependent variable is a characteristic that is influenced or modified by the presence of other variables, such as the independent variable of a study. In this case is the color of the leaf of a plant.

There is a lot of talk about gaps in the fossil record. This means that we do not necessarily have fossils for every organism that has ever lived. What do you think could account for these gaps in the fossil record?
Answers
Answer:
Explanation:
The rate decomposition of dead remains, to a large extent, determines whether there would be fossils left of the organism after it has been long gone or become extinct. Environmental factors (such as harsh weather condition and early insect invasion of dead remains) could increase the rate of decomposition of dead remains which could really make it difficult for fossils to be available for such organisms under these factors (especially if the organism is restricted to a particular region by nature) .

Two questions:
1. What are the 2 major functions of proteins?
2. Describe the structure of proteins.
Answers
Answer:
1. It helps repair and build your body's tissues and it also provides your body with a structural framework.
2. Protein structure is the three-dimensional arrangement of atoms in an amino acid-chain molecule.
Explanation:
Answer:
1-Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.
2-The overall structure of the protein includes both alpha helices (green) and beta sheets (red). The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape.

DNA replication is the process by which the DNA of a living organism is multiplied into two identical copies. DNA is a double-stranded molecule, hence, it must first be separated into two single strands in order to be replicated. The following are the orderly steps involved in DNA replication:An enzyme called DNA helicase unwinds DNA into single strands. A Y-shaped structure called replication fork is formed by the two single strands.DNA polymerase attaches to the primer, which is a short segment of RNA.
