This pulley has a mechanical advantage of 1 and does not make work easier has mechanical advantage of 2 and reduces the force needed to lift an object.
Answer:
The pulley with a mechanical advantage of 1 is called a fixed pulley. It does not provide any mechanical advantage and does not reduce the amount of force required to lift an object. It simply changes the direction of the force applied.
The pulley with a mechanical advantage of 2 is called a movable pulley. It reduces the force needed to lift an object by distributing the load between the force applied and the pulley itself. When using a movable pulley, the force needed to lift the object is half of the weight of the object.
A single pulley, a type of simple machine, has a mechanical advantage of 1 as it only changes the direction of force. Using combinations of pulleys increases the mechanical advantage, meaning the system can multiply forces, which reduces the energy required to lift an object.
Explanation:A pulley is a type of simple machine that serves to change the direction of the force. The mechanical advantage is the ratio of output to input forces for any simple machine. An individual pulley has a mechanical advantage of 1 because it only changes the direction of the force applied and not the force's magnitude. However, when pulleys are combined, as illustrated in Figure 9.27, they serve to multiply force and reduce the effort needed to lift an object.
For example, a pulley system with two cables attached to the load has a mechanical advantage (MA) of approximately 2. This means that the force applied is approximately twice the input force, thus reducing the effort needed to lift an object.
Note that while the machine can reduce the input force, energy is still conserved, and it cannot perform more work than the energy put into it.

A man heterozygous for blood type A marries a woman heterozygous for blood type B. What could be the possible blood types of their offspring?
Answer:
Heterozygous A: AO (remember, O type blood is a recessive allele. It's masked by A)
Heterozygous B: BB (h0m0zygous)
AO x BB --> AB, BO
Therefore, the genotypes of their offspring will be 1 AB to 1 BO, while the phenotypes will be 1 AB blood to 1 B blood.

Positive feedback restricts body temperature and keeps it controlled.C. Positive feedback systems don't work well with electrically charged neurons.D. Negative feedback systems balance the overall positively charged human organs.
Negative feedback systems are responses in your body that happen in order to maintain homeostasis and balance within a system. One example of negative feedback system is thermoregulation. If we did`nt have that, the temperature of our organisms would change drastically and it could cause bad consequences for our health and body functioning.

D. the electron transport chain
The two processes that must happen before cells can make large amounts of ATP for every glucose molecule split in two are: (D) The electron transport chain; and (C) The Krebs cycle.
What is ETC and Kreb's cycle?The Electron Transport Chain (also known as the ETC) is a sequence of electron complexes that electrons must travel through in order to generate ATP via redox reactions. There are four protein complexes that electrons go through on their way. Additionally, there is a fifth complex that is present at the very end that serves the role of the ATPase.
The Krebs Cycle is a set of chemical processes that work to oxidise acetyl coenzyme A (Acetyl CoA) and create energy as a byproduct of this process. Within the matrix of the mitochondria, the procedure is carried out.

The molecular structure of complex macromolecules show that a chemical reaction has occurred.
Answer:
The molecular structure of complex macromolecules show that a chemical reaction has occurred.
Explanation:
A macromolecule is defined as molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
Macromolecules are formed by chemical reactions between simple molecules which join together to give the macromolecule.
If we look at the structure of a macromolecule very closely, we will discover evidences that show that the complex structure of the macromolecule was created by stepwise chemical reactions.

the stages of mitosis and the process of cytokinesis draw and label a cell in each stage
These phases are prophase, prometaphase, and metaphase, Cytokinesis is the final physical cell division and is considered the sixth phase of mitosis.
What are the stages of mitosis and cytokinesis?Cytokinesis begins in the phase of cell division. and ends in telophase, extending completion as the next interphase begins. The first obvious change of cytokinesis in an animal cell is the sudden aspect of a pucker, or cleavage furrow, on the cell surface.
Mitosis and each of the two meiotic divisions result in two unrelated nuclei contained within a single cell. Cytokinesis performs a crucial process to separate the cell in half and ensure that one nucleus ends up in each daughter cell.
So we can conclude that Cytokinesis, the division of the cytoplasm to form two new cells, overhangs with the final stages of mitosis.

Emily has a maternal grandfather who is colorblind, which is an X-linked
recessive trait. Everyone else in her family sees normally. Emily's mom is
expecting a new baby girl. What is the chance that the new baby will also
be colorblind?
A. There is no chance that the new baby girl could be color blind.
B. There is no way to determine this from the information provided.
C. There is a 25% chance that the new baby girl will be colorblind.
D. There is a 50% chance that the new baby girl will be colorblind.
Answer:
A
Explanation:
the father doesn't have the trait and since it's recessive, there's no way the baby could have it even if the mother carries it from the grandfather.
There is a 25% chance that the new baby girl will be colorblind. Therefore, the correct option is C.
What is colorblindness?Color blindness is an X-linked recessive trait. This means that the gene responsible for color blindness is located on the X chromosome, and the trait is expressed only when there are two copies of the gene, one on each X chromosome, in females. Males have only one X chromosome, so they will express the trait if they inherit the colorblind gene.
In Emily's family, her maternal grandfather is colorblind. This means that Emily's mother is a carrier of the colorblind gene, since she does not have the trait herself. Emily's father must have two normal copies of the gene, since he does not have color blindness.
When Emily's mother and father have a child, there are four possible combinations of their genes that the child could inherit:
Normal X from mother, Normal X from father (25% chance)
Normal X from mother, Colorblind X from father (25% chance)
Colorblind X from mother, Normal X from father (25% chance)
Colorblind X from mother, Colorblind X from father (25% chance)
Only the last combination would result in a colorblind female, since she would have two copies of the colorblind gene. Therefore, the chance that the new baby girl will be colorblind is 25%.

what is the resting phase of the cell cycle called?
A. Prometaphase
B. Mitosis
C. Interphase
The resting phase of the cell cycle is called interphase.
Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.
This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.
Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.
