A strainer is like a filter that allows certain items through, but not others. Which of the following cell parts functions similarly to a strainer?
mitochondrion

cell membrane

⊝
nucleus. HELP PLEASEEE
Answers
Given what we know about biological structures, we can confirm that amongst the options listed, the one that most closely resembles the function of the strainer is the cell membrane.
A cell membrane is a barrier that acts as protection and provides mechanical support to a cell. The cellular membrane of a cell is composed of a bilayer of phospholipids, which contain a hydrophilic head towards the interior and exterior of the cell, and a hydrophobic pole directed towards the center of the membrane.
This design allows the cell membrane to be semi-permeable. What this means is that the cell membrane has the ability to allow the passage of certain substances like water and polar ions, while keeping unwanted substances out, much like the strainer described in the question.

Considering the function and composition of various types of shells, explain why turtles, clams, and crabs all have shells but are in different phyla.
Answers
Turtles, Clams, And Crabs all have shells but are grouped in different phyla because turtles' shells originated from rib bones million years ago and not from chitin seen in Clams and Crabs.
Turtles are ancestrally from the lizard and snake families. The early turtle are known for their hard ribs which protects them and also help in buoyancy.
Overtime, they started out as big rib bones which grew and hardened to become shell that are seen with modern turtles.
The shell serves as armour which protect them from being consumed by predators. And this is regarded as an adaptive feature for turtles survival in their habitat.

The diagram below compares the amounts of common elements found in the
human body.
Which elements are the labels 1 and 3 most likely to represent?
Answers
The most common element in the body is oxygen and the third most common element is hydrogen. So the correct option is C.
What is the chemical composition of the human body?Most of the elements that are present in the human body are present in the form of compounds. Six of the most common elements of the human body make up about ninety-nine percent of the mass of the human body.
These are
Oxygen - 65% Carbon - 18% Hydrogen - 10%Nitrogen - 3. 3%Calcium - 1.5%Phosphorus - 1%Thus, it's safe to say that oxygen is the most abundant element and hydrogen is the third most abundant element according to mass.
Water is the most common compound. One molecule of water has one oxygen and two hydrogen atoms. But the mass of the oxygen atom is more than the combined mass of two hydrogen atoms.
Therefore the correct option is C.

An oblique plane is a boundary between the false pelvis and true pelvis, and the circumference is called the pelvis brim.
What is the pelvis?
Basin shape structure supports the spinal column and also protects the abdominal column. pelvic consist sacrum, coccyx, and a pair of hip bones.
The pelvic brim consists sacral segment, iliac, and pubis portion, but ischium is not present in the pelvic brim, the false pelvis and true pelvis boundary is the oblique plan.
The false pelvis is a region of the abdominal cavity but not a region of the pelvic cavity, but the true pelvis contains the bladder, pelvic colon, rectum, and reproductive organ.

Answer:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

In a species of lizard you can see two main phenotypes, brown and green, recently
there have been sightings of a brown lizard with green spots running around! If this
truly is the case what can you infer from this data?
A. the lizards are exhibiting codominance
B. the lizards are exhibiting multiple alleles
C. the lizards are exhibiting incomplete dominance
D. the lizards are normal
Answers
Answer: the lizards are exhibiting codominance
Explanation: I just took the test and it was correct.
In the lizards that are brown with green spots, co-dominance is being exhibited.
Genes often occur in pairs called alleles. One gene is usually expressed anytime it is present and it is called the dominant gene. The other is not expressed in the presence of the dominant gene and it is called the recessive gene.
However, when two genes are expressed together such as in the case of the brown lizard with green spots, this is a case of co-dominance.

Answers
Answer:wolf & owl
Explanation:
Just took the quiz
The organisms that are likely to be found in the level labeled 4 in the diagram are Wolf and Owl.
What is Trophic levels?Trophic levels refer to the feeding positions of organisms in a food chain or food web. They are often used to describe the transfer of energy and nutrients through an ecosystem.
In a food chain, the trophic level is determined by the position of an organism in the chain relative to the primary source of energy, which is typically the sun.
Trophic level 4 represents tertiary consumers, which are carnivores that feed on other carnivores. The wolf is a tertiary consumer that feeds on other carnivores such as coyotes, foxes, and sometimes other wolves. The owl is also a tertiary consumer that feeds on other carnivores such as mice, rats, and other birds.
Therefore, options A and E, which represent the Wolf and Owl, respectively, are the correct answers. Options B, C, and D represent organisms that are not likely to be found in trophic level 4.
