which animal phylum includes tapeworms and has members that are acoelomate and that exhibit bilateral symmetry?
Answers
The animal phylum that includes tapeworms and has members that are acoelomate and exhibits bilateral symmetry is the Platyhelminthes phylum.
What is the Platyhelminthes phylum?
Platyhelminthes, commonly known as flatworms, is a phylum of relatively simple acoelomate invertebrates. This phylum includes tapeworms as well as a wide range of free-living species. Members of this phylum are distinguished by their flattened, ribbon-like bodies, which lack a specialized respiratory or circulatory system, making them acoelomates.
Characteristics of Platyhelminthes:
The Platyhelminthes phylum exhibits bilateral symmetry, which means that their body can be divided into two halves, with identical left and right sides. They have a well-defined head region with an anterior end, and most of them have a centralized nervous system. Their digestive system is incomplete, consisting of a single opening that serves as both the mouth and anus. The Platyhelminthes phylum is composed of approximately 25,000 species of flatworms that are found in both freshwater and marine habitats.

Tell me what you know about nerve cells and how they create an imbalance in their electrical gradient. What causes that and how does it create a nerve impulse? Give very descriptive details
Answers
The resting membrane potential, often known as the resting potential, is a voltage across the membrane of a dormant (non-signaling) neuron.
What is electric Gradient?Ion concentration gradients across the membrane and the permeability of the membrane to each kind of ion dictate the resting potential. In neurons, an electrical gradient is used as a mode of information transfer.
At resting potential, the nerve is at -70 mV which is maintained by the sodium-potassium pump. This uses ATP to move three sodium ions out of the cell and two potassium ions into the cell. The potassium leak channel also contributes to this resting potential as potassium ions diffuse out of the cell to maintain the potential.
Due to the difference in electrical charges in the intracellular and extracellular fluid, an electrical gradient is formed. The gradient, if unmaintained, would balance the charges of the intracellular and extracellular fluid, as the sodium ions would move into the cell.
Therefore, The resting membrane potential, often known as the resting potential, is a voltage across the membrane of a dormant (non-signaling) neuron.

What might be the correlation between the clarity of the lake water and the occurrence of the full body plate trait? What might you conclude about the clarity of the water from 1950 to 1980 based on this correlation?
Answers
Answer:
The clarity of the lake water isn’t specified so assuming the clarity improved and other predatorial fish were able to target stickleback fish more easily the full body plating had to come into play to make it more difficult for them to be preyed upon and to give them a better chance at escape.
Explanation:
The clarity of the lake water though not specified in this context. The full
body plate will help the stickleback fish to escape from its predators.
Water clarity is defined as the amount of light which is able to penetrate into
water bodies thereby making it easier for animals in it to see and hunt
properly for their food.
The improvement in water clarity will give the predatorial fish an advantage
to easily hunt stickleback fish. The full body plate trait will therefore give it a

much should they charge per apron?
Answers
Answer:
Each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.
Explanation:
Since the fifth grade craft club is making aprons to sell, and each apron take 1.25 yards of fabric that costs $ 3 per yard and 4.5 yards of trim that costs $ 2 per yard, to determine what does it cost the club to make one apron, and, if the club wants to make $ 1.75 profit on each apron, how much should they charge per apron, the following calculations must be performed:
1 apron = 1.25 yards of fabric at $ 3 per yard and 4.5 yards of trim at $ 2 per yard
1.25 x 3 + 4.5 x 2 = X
3.75 + 9 = X
12.75 = X
12.75 + 1.75 = 14.50
Therefore, each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.
what role does serum albumin play in fat metabolism? a. it is a component of the chylomicron lipoprotein. b. it acts as a carrier for free fatty acids in the bloodstream. c. it binds hormone-sensitive lipase that is responsible for the release of triglycerides from adipocytes. d. it is involved in the transport of short-chain fatty acids across the plasma membrane. e. it is important in the transport of ketone bodies from the liver to the brain.
Answers
The role that serum albumin plays in the fat metabolism is option B: it acts as a carrier for free fatty acids in the bloodstream.
By binding fatty acids and maintaining them in the plasma in a soluble form, serum albumin plays a significant part in the metabolism of fat. With roughly 7 binding sites for fatty acids with moderate to high affinity, it serves as the primary fatty acid binding protein in extracellular fluids.
It also increases the content of fatty acids by several orders of magnitude. This is one of the causes of hyperlipemia with clinically significant hypoalbuminemia. Serum albumin serves as a carrier for free fatty acids in the bloodstream, hence option b is the correct one.

Answers
Answer:
The reactants and enzymes required for a particular biological process are concentrated in a particular organelle.
Slower
Explanation:
Enzymes are usually localized in organelles to make it easier for cellular processes to occur. Enzymes are NOT randomly distributed in the cell. Each organelle is capable of a specific function and uses specific enzymes to do these processes. Enzymes are very specific and only work for certain organelles, so they are appropriately distributed throughout cells to ensure biological processes can proceed appropriately. This is also why processes would run slower if they were just in the cytoplasm, because organelles have reactant-specific enzymes to do certain biological processes, which cannot be effectively done in the cytoplasm in the cell.

you are given two populations of true-breeding tomato plants with two traits that assort independently. using the multiplication rule, how many of the f2 progeny would you expect to have a recessive phenotype for both traits?
Answers
To calculate the number of F2 progeny with a recessive phenotype for both traits in true-breeding tomato plants, we will use the multiplication rule. To calculate the number of F2 progeny with a recessive phenotype for both traits in true-breeding tomato plants, we will use the multiplication rule.
If the two traits in the tomato plants assort independently, then we can consider them separately. Let's call the two traits A and B. For population 1, we know that all individuals have the homozygous dominant genotype for trait A (AA) and the homozygous recessive genotype for trait B (bb). For population 2, we know that all individuals have the homozygous recessive genotype for trait A (aa) and the homozygous dominant genotype for trait B (BB). To determine the genotype of the F1 generation, we need to cross an individual from Population 1 with an individual from Population 2. The resulting F1 individuals will all be heterozygous for both traits (AaBb). The rule states that the probability of two independent events occurring together is equal to the product of their individual probabilities. Using the multiplication rule, we can multiply these probabilities together: 1/4 x 1/4 = 1/16 Therefore, we would expect 1/16 or 6.25% of the F2 progeny to have a recessive phenotype for both traits.

The blood travels from the plantar arch to the right atrium through a series of major veins, including the popliteal vein, femoral vein, iliac vein, and inferior vena cava.
Below is a list of the major veins: Plantar arch to popliteal veinThe plantar arch, also known as the dorsal arterial arch, is a blood vessel in the foot that is responsible for supplying blood to the toes and foot. From the plantar arch, blood flows to the posterior tibial veins, which then lead to the popliteal vein.
Popliteal vein to femoral vein. The popliteal vein runs through the leg and leads to the femoral vein, which is a large blood vessel in the thigh that carries blood from the leg to the heart.
Femoral vein to iliac vein. The femoral vein leads to the iliac vein, which is located in the pelvis. The iliac vein is responsible for carrying blood from the leg and pelvis to the heart.
Iliac vein to inferior vena cava. The iliac vein joins with the inferior vena cava, which is a large vein that carries blood from the lower half of the body to the heart. The inferior vena cava then leads to the right atrium of the heart.
