in a typical animal, mitosis produces _________, while meiosis produces____________.
In a typical animal, mitosis produces two identical daughter cells, while meiosis produces four unique daughter cells.
Meiosis is a type of cell division that involves the parent chromosome being halved and then divided again to form four unique daughter cells which have only one copy of chromosome from the parent.
This process occurs in sex cells such as the sperm and egg cells.
Mitosis is also a type of cell division but occurs with the parent cells to form two identical daughter cells.
This type of cell division have produces the same number of chromosomes the parents have and occurs in cells of the body which undergoes growth or during replacement of worn-out tissues.

how does oxygen have a direct effect on sea urchins
Answer:
When the oxygen level is low in a Purple Sea Urchin, muscles associated with Aristotle's Lantern pump fluid through its body (through the canals). Carbon dioxide (waste/not good stuff) is released through the anus. The Purple Sea Urchin obtains oxygen through diffusion only (the diffusion of oxygen into the organism).
Explanation:
Brainliest please
Sea urchins breathe through their feet tubes because of nonavailability of lungs and gills in them. When the oxygen level is low at that time, the sea urchins pump fluids through their anus.
How are sea urchins able to survive sea ?Sea urchins are able to survive in sea because of the tiny hair called spines present on their body as water currents are created because of the hair and waste gets washed away with the water currents created.
When the carbon dioxide level gets increased in the sea at that time the skeletal structures of the marine animals are also affected.
The shells made up of calcium also gets affected because of the increasing acidity in the water. Carbon dioxide not so good is released through the anus and this totally affects the normal regulation of the creature.

Answer:
Describe the appearance of the vacuole in a well-watered plant. What effect would this have on the cell wall of the plant? The vacuole would expand and take up most of the space inside the cell. This would create internal pressure on the cell wall.
Explanation:
(a) Identify the most likely mode of transport across the membrane for substance L. Explain how information provided helps determine the most likely mode of transport.
Active transport occurs against the electrochemical gradient. It needs energy to move molecules from the lower concentration side to the higher concentration side. The mode of transport is active transport.
-------------------------------------------------
There are three main different types of transport across the membrane
Simple diffusion ⇒ Does not need energy to occurFacilitated transport ⇒ Does not need energy to occurActive transport ⇒ Needs energy to occurActive transport is the transport of molecules that move against the electrochemical gradient, so it does need energy to happen.
Molecules move from the lower concentration side to the higher concentration side of the membrane.
Carrier proteins are in charge of active transport. The needed energy might proceed from the ATP molecules or the membrane's electric potential.
In the exposed example, a scientist wants to determine how substance L enters a cells in a culture.
The cells maintain a 120 mM intracellular concentration of substance L. Varying external concentrations of substance L (10 to 100 mM) in culture medium (Table 1).Table 1. Rate of entry of substance L into mammalian cells in culture
External concentration of substance(mM) Rate of entry of substance L
10 5%
20 25%
30 45%
40 65%
50 80%
60 90%
70 95%
80 100%
90 100%
100 100%
Now, we need to identify the most likely mode of transport across the membrane for substance L, and explain how information provided helps determine the most likely mode of transport.
We know that the intracellular concentration is 120mM.
As we can see, this concentration exceeds all of the culture media concentrations. Yet, the substance keep moving into the cell.
As the concentration inside the cell is always higher than the concentration outside, we can assume that this is not passive transport because the molecule transport is going against its concentration gradient.
Hence, the remaining option is active transport. And as said before, we can see it because the substance keeps crossing the membrane toward the cell interior despite its concentration being higher in the interior of the cell than in the exterior.

Wha is biology and how it started and what kind of biology is this
Answer:
Basically biology traces the study of the living world from ancient to modern times. Although the concept of biology as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to Ayurveda, ancient Egyptian medicine, and the works of Aristotle and Galen in the ancient Greco-Roman world. This ancient work was further developed in the Middle Ages by Muslim physicians and scholars such as Avicenna. During the European Renaissance and early modern period, biological thought was revolutionized in Europe by a renewed interest in empiricism and the discovery of many novel organisms
