Leeches are soft, squishy animals with long, tube-like bodies that are made of many repeating segments. They contain
a heart that pumps blood through their bodies and survive by attaching to other organisms and sucking their blood.
What animal phylum do leeches belong in?
arthropods
echinoderms
chordates
annelids
Answer:
annelids
They are annelids because they have soft, squishy bodies.
So, they are annelids, like earthworms.
Hope it helps!
Answer:
The answer is annelids.
Explanation:

Part A of the cell membrane is composed of which of the following?
Choose 1 answer:
Choose 1 answer:
(Choice A)
A
The hydrophobic tails of the phospholipid molecules.
(Choice B)
B
Proteins attached to the heads of the phospholipid molecules.
(Choice C)
C
Both the heads and the tails of the phospholipid molecules, arranged randomly.
(Choice D)
D
The hydrophilic heads of the phospholipid molecules.
Answer: A: The hydrophobic tails of the phospholipid molecules.
Explanation: The hydrophobic, or ''water-fearing,'' fatty acid tails face inward, trying to get away from the aqueous solution found on either side of the cell membrane. Hope this helped have a nice day. :)
The cell membrane is composed of the hydrophobic tails of the phospholipid molecules. Therefore, option (A) is correct.
What are the functions of cell membrane?The identification, communication, regulation of solute exchange through the membrane, and isolation of the cytoplasm from the external environment are the four primary functions of the plasma membrane.
Membranes in biology serve three primary purposes: they prevent harmful substances from entering the cell; they have receptors and channels that make it possible for specific molecules, like ions, nutrients, wastes, metabolic products, and toxins, that mediate cellular and extracellular activities.
The substance's entry and exit from the cell are controlled by the membrane, which is selectively permeable. Protection from the external environment is one of the functions.

(c) Many bacterial diseases can no longer be treated with antibiotics. Outline how
antibiotic-resistant strains of bacteria can develop.
Antibiotics kill or inhibit the growth of susceptible bacteria. Sometimes one of the bacteria survives because it has the ability to neutralize or escape the effect of the antibiotic; that one bacterium can then multiply and replace all the bacteria that were killed off. Exposure to antibiotics therefore provides selective pressure, which makes the surviving bacteria more likely to be resistant.
Why is the plasma membrane selective?
so water cannot enter or exit the cell
so waste products do not enter the cell
so lipid-soluble molecules do not enter or exit the plasma membrane unassisted
so large molecules can pass through the plasma membrane unassisted

C

How are detritovores different from decomposers?
a. Detritovores eat the detritus, decomposers break down dead material into detritus
b. Both detritovores and decomposers do the same thing, they are not different.
c. Decomposers eat detritus that the detritovores make.
d. Decomposers always eat dead material and detritovores sometimes use photosynthesis to get energy.
Answer:
I think it's option B
Explanation:
Decomposers like bacteria and fungi don't eat their food, they decompose it externally. Also, decomposers consume nutrients on a molecular level while detritivores eat large amount of decaying material and excrete nutrients.
Hope it helps ;)
Using the data, choose one of the 3 possible problems below. Justify your choice by writing a hypothesis to explain how it has stopped Claire from breaking down her food. The hypothesis is your first explanation. You will be able to revise it as you do more experiments.
Low Enzyme Production is the reason for no breaking down of food.
If the digestion of food did not occur so it means that there is low enzyme production because enzymes are responsible for the breaking down of food substances into simpler ones in order to absorb by the cells for the generation of energy in the form of ATP. So we can conclude that low enzyme production is the only reason for the stopping of breaking down or digestion of food.

the current theory of the structure of the plasma membrane is best described by the what model
Answer:
The fluid mosaic model
Explanation:
The fluid mosaic model describes the structure plasma membrane as a flexible barrier that contains various different components (a mosaic). These components include the phospholipid bilayer, as well as the proteins and other lipids and carbohydrates that are embedded in it. These different components give the membrane its fluid characteristics.

What is volume?
Describe the standard units of liquid volume.
What is mass (weight)?
Describe the standard units of mass.
Answer:
Explanation:
1. "Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre. "
2. "In the CCSS, the unit of liquid volume introduced in Grade 3 is liter (L), which is a standard unit in the metric (or SI) system. Another commonly used unit of liquid volume is milliliter (mL), where 1000 mL = 1 L. Many soda bottles are 500 mL, 1L or 2L."
3. "The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it."
4. "The standard International System of Units (SI) unit of mass is the kilogram (kg). The kilogram is 1000 grams (g), first defined in 1795 as one cubic decimeter of water at the melting point of ice."

For what purpose do lipids accumulate in connective tissue?
Answer:
the lipids accumulate in connective tissue is used for complex cleaning purpose
Lipid accumulation product (LAP) is an index, which combines waist circumference (WC) and triglyceride (TG) reflecting lipid accumulation. Lipids are available to the body from three sources. They can be ingested in the diet, stored in the adipose tissue of the body, or synthesized in the liver. Lipid storage (especially sphingolipid and unesterified cholesterol) is found in liver and spleen. In the brain, glycolipid storage predominates, often with some decrease in myelin white matter. The condition is inherited as an autosomal recessive trait.
