Why is the absence of a cell wall an advantage for animal cells?
Answer:
It is a advantage because the animals can move around freely without escaping
Explanation:
Answer:
Animals do not have cell wall cause they don't need them , cell wall which are found in cell, maintain cell shape almost as if each cell has it's own exoskeleton . this rigidity allows plants to stand upright without the need for bones .
Explanation:
organisms that use sunlight to produce energy-storage molecules are called- a.heterotrophs b. producers composers d. decomposers
Answer:
i think its B.
Explanation:
Since there are no constructive (volcanic activity) or destructive (erosion) forces at work under the ocean, the ocean floor is flat.
True
False
False so false
Ik it cant be true because there are underwater volcanoes and the earths plates are constantly moving.

Dr. Jamani suspects that her patient is suffering from deep vein thrombosis. What can this condition lead to? hypertension coronary disease cardiac dysrhythmias pulmonary embolism
Answer: Pulmonary Embolism
Explanation: Deep Vain Thrombosis occurs when a blood clot forms in a vein located deep inside your body. Deep vein blood clots typically form in your thigh or lower leg, but they can also develop in other areas of your body. A blood clot is a clump of blood that's turned to a solid state. In most cases, pulmonary embolism is caused by blood clots. Pulmonary embolism is a blockage in one of the pulmonary arteries in your lungs.
Answer:
D
Explanation:
Describe the path blood takes through the circulatory
system starting with the heart and ending with the heart.
Why are endocytosis and exocytosis kinds of active transport?
Explanation: During endocytosis (endo means inside) a cell will use its cell membrane to engulf an object which is outside of the cell. This process takes effort by the cell, so it needs to use energy (ATP!) The process which is the reverse of endocytosis is exocytosis (exo means outside - think exit).
Answer:
Endocytosis and exocytosis are active transport mechanisms in which large molecules enter and leave the cell inside vesicles. In endocytosis, a substance or particle from outside the cell is engulfed by the cell membrane. The membrane folds over the substance and it becomes completely enclosed by the membrane.

The southern United States experiences periodic occurrences of severe cold and drought conditions. Which weather phenomenon most likely causes this and why?
La Niña, because the jet stream is displaced southwards
La Niña, because the jet stream is displaced northwards
El Niño, because of increased upwelling of cooler waters
El Niño, because of decreased upwelling of cooler waters
Answer:
D give Brainlist
Explanation:
La Nia is a climatic phenomenon that causes the surface ocean water temperature along South America's west coast to decrease. It causes the sea water's temperature to be lower than usual, hence option D is correct.
Why are periodic occurrences of severe cold and drought conditions?Lower temperatures lead the central and eastern Pacific to have higher than usual pressure, which reduces rainfall. Due to up-welling, rainfall decreases as cloud formation does.
The "ENSO," also known as the El Nino-Southern oscillation, is a cyclical climate phenomenon that periodically affects the tropical Pacific. Its warm and cool periods are called El Nino and La Nina, respectively.
Therefore, the trend switches back and forth occasionally every two to seven years, disrupting tropical wind and rainfall patterns, hence option D is correct.

as cell size increases the surface area to volume ratio
Answer:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

Bones and cartilage are connective tissues’ prove this with evidences.
Answer:
hope it helps : )
Explanation:
Cartilage and Bone are specialized forms of connective tissue.
They are both made up of cells embedded in an extracellular matrix.
It is the nature of the matrix that defines the properties of these connective tissues.
Cartilage is thin, avascular, flexible and resistant to compressive forces.
Bone is highly vascularized, and its calcified matrix makes it very strong.

what cells make up the monkeys in Osmosis Jones
Answer:
im guessing white blood cells i have never seen osmosis jones sorry :(
Explanation:
The cells that make up the monkeys in Osmosis Jones are known as White blood cells.
What is Osmosis?Osmosis may be defined as the process that significantly involves the movement of water from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a semi-permeable membrane.
White blood cells play numerous important functions in the body of each and every living organism. They perform the function of protecting the body against infections. These cells have an important role in inflammation along with allergic responses.
There are two types of white blood cells that are considerably formed in the bone marrow. They are phagocytes and lymphocytes.
Therefore, the cells that make up the monkeys in Osmosis Jones are known as White blood cells.
