The process of meiosis does all of the following except:
Goes through two rounds of division.
Forms sex cells or spores.
Results in four unique haploid cells.
Produces two genetically identical cells.
Answer:
The last one does not happen meiosis create four genetically different haploid cells
Meiosis, on the other hand, creates four distinct daughter cells, each of which has half as many chromosomes as the parent cell. Thus, option D is correct.
What are the advantages of meiosis?Meiosis is crucial for three reasons: it promotes genetic diversity, sexual reproduction of diploid species, and the correction of genetic flaws.
A parent cell undergoes mitosis, which creates two identical daughter cells with the same number of chromosomes.
Genotypic diversity is produced, and appropriate homologous chromosomal segregation is ensured via meiotic crossing over.
Despite these functions, very little is known about the genetic and population genetic mechanisms that resulted in the evolution of species-specific variations in recombination rates.
Therefore, process of meiosis produces two genetically identical cells.

how does carbon dioxide pass through the stomata of a leaf?
Answer:
Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata. These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.
Answer:
small holes on underside

What do you know about deserts, grasslands, or tundra biomes?
Answer:
this is what i do when i bored :P
Explanation:
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. Grasslands are areas where the vegetation is dominated by grasses. However, sedge and rush can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. In physical geography, tundra is a type of biome where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes through Russian тундра from the Kildin Sámi word тӯндар meaning "uplands", "treeless mountain tract".
Describe what needs to occur in order for a metamorphic rock to form.
If your not gonna put a HELPFUL ANSWER, please do not answer, thanks.
Answer:
Any sort of prexisting rock whether sedimentary, igneous, or even metamorphic rock must change under extreme conditions like extreme heat or pressure.
Explanation:
An igneous rock is a rock that has been created via cooling of magma.
A sedimentary rock is formed from sediments, whether they be natural like seashells, or other pieces of older rocks that have worn away. usually formed under pressure.
A metamorphic rock is a rock that's changed, because it was put under extreme pressure or exposed to extreme heat.
Think of the part morphic in the word metamorphic-it literally means that it morphed or that it changed dramatically.
There are two ways for a rock to become metamorphic under extreme pressure or extreme heat. and there are two types of metamorphic rocks, contact metamorphism and regional metamorphism.
Those mean pretty much exactly what they say.

A chemical
B sound
C. electrical
D. light
Answer:
a
Explanation:
cause apple not get sound electrical or light energy
Answer:
A chemical
Explanation:
when you eat an apple: The carbohydrate breaks down into a sugar called glucose and enters your bloodstream (where it's termed “blood sugar”). That sugar travels to your cells, where it's turned into energy for your body.
An apple doesn't produce sound, electrical or light energy therefore the answer is chemical energy

the diagram below represents a portion of a cell membrane. The arrow indicates that the cell membrane is carrying out the process of...
Answer:
In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.
Explanation:
Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.
The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.
The other options presented are not correct, because
Respiration is a process that occurs in the mitochondria.Diffusion is a passive transport process that does not require energy.Cellular recognition depends on membrane proteins that act as specific receptors.

Important Ions move from low to high concentration while using a membrane protein. Which of the following is true? Question 5 options:
A. It's moving down the concentration gradient.
B. Energy is needed to make this happen
C. It's facilitated diffusion.
D. It's osmosis.
Answer:
A) it is moving down the concentration gradient
Explanation:
Brownian motion will cause the molecules (or ions) to spread/diffuse from where they are more concentrated to where they are less concentrated until they are equally distributed in that space (Figure). When molecules move in this way, they are said to move down their concentration gradient.

Cells in every part of an earthworm's body need oxygen. Which TWO statements explain how an earthworm's organ systems help provide its cells with oxygen?
A. The nervous system removes oxygen from the body
B the circulatory system carries oxygen to different parts of the body.
C the respite system brings oxygen into the body
D the digestive system delivers oxygen to the blood.
The circulatory system carries oxygen to different parts of the body, and the respiratory system brings oxygen into the body are the two statements which explain how an earthworm's organ systems help provide its cells with oxygen. Therefore, the correct option is B and C.
What are organ systems?The term organ system refers to the group of organs that work together to perform one or more functions of the body.
Earthworms have a closed circulatory system, which means that blood flows within vessels. The circulatory system carries oxygen from the respiratory surface (the skin) to different parts of the body, where it can be used by the cells for respiration.
Earthworms breathe through their skin, which is kept moist by mucus. Oxygen diffuses across the moist skin and into the circulatory system, where it is carried to the cells.
Both A and D are incorrect because both of these systems are not involved in carrying or delivering oxygen to or from the blood. Therefore, the correct option is B and C.

Explanation:
The time it takes for an animal to metabolize a drug to a non-detectable levels could be ____ than that of the withdrawal period 
A:Longer
B:Shorter
C:Same time
The time it takes for an animal to metabolize a drug to a non-detectable levels could belongerthan that of the withdrawal period. Hence the correct option is A.
The metabolism of a drug refers to the process by which the body breaks down and eliminates the drug from the system. The withdrawal period is the time required after administering a drug during which the animal must not be slaughtered for human consumption to ensure that no residues of the drug are present in the edible tissues.
There are several factors that can influence the metabolism of a drug in animals, such as the drug's chemical properties, the animal's species, age, health status, and metabolic rate. Some drugs may be metabolized relatively quickly, while others may take longer to be completely eliminated from the system.
Hence the correct option is A.
