option 1,3, and 4
-Membrane proteins may be enzymes to catalyze metabolic reactions within the cell.
-Channel proteins allow a specific molecule to cross the cell membrane that is unable to cross the phospholipid bilayer unassisted.
-Receptor proteins bind to ligands, initiated cell signaling pathways.
Explanation:
I did the assignment on USATestprep and got them right.
The statements accurately reflect the structure and function of the phospholipid bilayer are:
1. Membrane proteins may be enzymes to catalyze metabolic reactions within the cell.
3. Channel proteins allow a specific molecule to cross the cell membrane that is unable to cross the phospholipid bilayer unassisted.
4. Receptor proteins bind to ligands, initiating cell signaling pathways.
What are phospholipids?Phospholipids are distinct compounds with many uses. They are common and serve as the primary building blocks of cellular membranes.
Phospholipids, which are arranged as lipid bilayers, are crucial for the composition and operation of biological membranes. These layers contain proteins and carbohydrates that help in the transport of material from and to the cell.
Therefore, the correct options are 1, 3, and 4.

Explanation:
What does ATP mean?
ATP stands for adenosine triphosphate. It is a molecule found in the cells of living organisms. It is said to be very important because it transports the energy necessary for all cellular metabolic activities. ... Without ATP, various metabolic activities in the human body cannot take place.
The main function of ATP?
ATP functions as the energy currency for cells. It allows the cell to store energy briefly and transport it within the cell to support endergonic chemical reactions. The structure of ATP is that of an RNA nucleotide with three phosphates attached.

Answer:
Explanation:
ovaries
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.

The process when rocks break into smaller pieces due to exposure to
natural elements is called
Answer:
Weathering.
Explanation:
Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.
The process when rocks break into smaller pieces due to exposure to natural elements is called weathering.
What is weathering?Weathering can occur through physical, chemical, or biological means.
Physical weathering involves the mechanical breakdown of rocks into smaller fragments without changing their chemical composition. Chemical weathering, on the other hand, involves the breakdown of rocks through chemical reactions, resulting in the formation of new minerals. Biological weathering is caused by living organisms, such as plants and animals, that can physically break down rocks or release chemicals that can alter the rocks' composition.

Analyze the example of gene expression of the bacteria below:
In this example, what would cause the genes to be expressed?
An operon that is turned off
Polymerase being blocked from bonding to the DNA
The presence of an active repressor
A repressor that is unable to bond to the DNA
Answer:
This question is incomplete as it lacks the image. The answer is:
D. A repressor that is unable to bond to the DNA
Explanation:
The expression of a gene in a prokaryote like bacteria is regulated at the transcription level. Normally, a Gene is expressed by first undergoing transcription from DNA to mRNA with the aid of an enzyme called RNA polymerase.
However, a protein called REGULATORY PROTEIN which serves as a repressor inhibits the binding of RNA polymerase to the DNA sequence. According to this question, the gene will only be expressed if the repressor is unable to bond to the DNA, hence, not being able to prevent transcription.

Which of the following is NOT a reaction of the
parasympathetic nervous system?
A. Decreased respiration
B. Decreased heart rate
C. Increased blood flow to digestive tract
D. Decreased saliva production
Answer:
D
Explanation:
D, or decreased saliva production is not a reaction of the parasympathetic nervous system (PSNS) since the PSNS actually increases/causes salivation which helps you digest your food.
As a tip, I usually associate the PSNS with a state of rest/restful conditions, as opposed to the sympathetic nervous system which is the opposite and is associated with stress and high-pressure conditions (like fight or flight).

Discuss the mechanisms of speciation
Answer:
There are four major variants of speciation: allopatric, peripatric, parapatric, and sympatric. Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.

2. Consider a well-trained 130-pound female marathon runner, Jordan. Jordan has just loaded up on a carbohydrate meal and has the maximum amount of stored glycogen (6.8 grams of glycogen per pound of body weight). (10pts) a. How many grams of glycogen is Jordan storing in her body? Show your calculations
Answer:
884 grams of glycogen
Explanation:
Jordan's body weight = 130 pounds
Rate of storage of glycogen per pound of bodyweight = 6.8 grams
Total grams of glycogen that Jordan can store at maximum capacity:
bodyweight x rate of storage
= 130 x 6.8 grams
= 884 grams
Hence, Jordan is storing 884 grams of glycogen in her body.
