Meiosis is a process used by many organisms but not all organisms. What organisms or
habitats would make mitosis a better reproductive option than meiosis?
Meiosis does not occur in archaea or bacteria, which reproduce via asexual processes such as mitosis or binary fission. ... Because the chromosomes of each parent undergo genetic recombination during meiosis, each gamete, and thus each zygote, will have a unique genetic blueprint encoded in its DNA.

What is the difference between dominant and recessive traits?
Answer:
Dominant trait is the trait that the offspring are more likely to have, like if a dominant trait is to have green eyes and the recessive trate is blue eyes, then the offspring are more likely to have green eyes, but its likely to have blue eyes too.
Dominant traits show up more than the recessive trait, because its stronger than the recessive trait.
Explanation:
Answer:
Dominant traits are traits that are always expressed when the connected allele is dominant. This is for even if only one of the copy of the dominant traits exist. Dominant traits are always written in capital letters. An example of dominants traits would be BB or Bb.
Recessive traits are traits that are only expressed if both of the alleles are recessive. A recessive trait is always written in a lowercase letter. An example of recessive traits would be "bb".
Also, Dominant traits are traits that are more common to people. It is strong. For example, if you are right handed, that is a dominant trait. Being right handed is a common thing in this world. 90% of the world's population is right handed.
On the other hand, recessive traits are traits that are rare to people. It is weak. For example, if you are left handed, that is a recessive trait. Being left handed is a rare thing for people in this world. Only 10% of the world's population is left handed.

Raya conducts an experiment to study the effect of altitude on the growth of plants she gathered plant samples and places them on five different floors of a 20-story building identify the basic components of Ray experiment including the compounding variable
Answer:
Independent variable: ALTITUDE
dependent variable: GROWTH OF PLANTS
Confounding variable: STOREYS OF THE BUILDING
Explanation:
In an experiment, the basic components i.e primary variables that an experiment should contain, are the independent and dependent variables.
- The independent variable is the variable that is changed or manipulated in an experiment. In this experiment, the ALTITUDE of the plant is the independent variable.
- The dependent variable is the variable that responds to changes to the independent variable. It is the variable measured in an experiment. In this case, the dependent variable is the GROWTH OF THE PLANTS.
- The confounding variable is a variable that has an extra influence on the outcome of the experiment. In other words, the confounding variable has an impact on the dependent variable. In this case, the confounding variable is the STOREYS OF THE BUILDING.

How can stem cells help a patient.
Answer:
In stem cell transplants, stem cells replace cells damaged by chemotherapy or disease or serve as a way for the donor's immune system to fight some types of cancer and blood-related diseases, such as leukemia, lymphoma, neuroblastoma and multiple myeloma. These transplants use adult stem cells or umbilical cord blood.

How does Cellular Respiration add carbon to the Carbon Cycle?
during the carbon cycle animals and plants out carbon dioxide to the atmosphere through cellular respiration and plants remove carbon dioxide through photosynthesis

Photosynthesis is done only by plants by using sunlight water and CO2
All living organisms can do cellular repirations
She is wrong because she said plants only do photosynthesis but that's not true because trees do cellular repiration too because when there is no sunlight they need energy. So what they do is they break down the sugar doing glycolysis by using mitochondria. Sidenote:Both plants and animals have mitochondria in their cells.They need energy right when there is no sun.So they use glycolysis.Glyco means sugar and lysis means break down.Then there come 2 steps.
Aerobic Respiration
Anaerobic Repiration
If the sugar that we just break down contains oxygen the that sugar falls to the aerobic respiration
If it does not contain sugar it goes to Anaerobic Respiration
Aerobic Respiration : It would use Kreb Cycle to Make 2 ATP.ATP is for Adension Tri Phosphate. Which is basically enregy.Then there comes Electron Transport Chain.Where they use protons to gain 32 ATP.Overall
2 ATp from glycolysis 2 from Kreb Cycle and 36 from ETC so 36
Anerobic: They fall part to 2 major respirations of this section which are
1. Alcoholic Repiration - It contains no oxygen, gain 2 atp and used to make breads and alcohol
2.Lactic Acid - gain 2 ATp and no oxygen and used in yogurt you eat and it creates sore in your muscles
She is wrong because that is completely wrong statement that trees only do photosynthesis but no they use cellular Respiration to gain energy from ATP when there is no sun available to them

The attraction that causes water and other liquids to form drops on thin
films is called______.
This is also water's ability to be attraction
to other water molecules.
A.)cohesion
B.)adhesion
C.)capillary action
D.)surface tension
Answer:
Cohesion is an attraction between substances of the same kind. Because of cohesion, water and other liquids form thin films and drops. Molecules at the surface of water are linked together by hydrogen bonds like a crowd of people linked by holding hands.
The attraction that causes water and other liquids to form drops on thin films is called cohesion.
Thus, option A is correct.
What is cohesion?
Cohesion is defined as attraction of molecules for other molecules of the same type and molecule of water have strong force of cohesion.
Cohesion is a property of same molecules of the same substance that stick to each other due to mutual attraction.The attraction that causes water and other liquids to form drops on thin films is called cohesion.
The properties of matter include a character that can be measured, such as object's color, mass, density, melting point, odor and temperature.Cohesion is defined as attraction of molecules for other molecules of the same type and molecule of water have strong force of cohesion.
Solid have high cohesive properties so they do not stick to the surface in which they come in contact.The properties of matter include a character that can be measured, such as object's color, mass, density, melting point, odor and temperature.
Therefore,the attraction that causes water and other liquids to form drops on thin films is called cohesion.
Thus, option A is correct.

In what state is carbon dioxide in the atmosphere
CO2 exist in the earth'a atmosphere as a gas and in its solid state it known as dry ice.
What are the functions of carbon dioxide?Carbon dioxide is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature.
CO2 plays various roles in the human body including regulation of blood pH, respiratory drive, and affinity of hemoglobin for oxygen (O2). Fluctuations in CO2 levels are highly regulated and can cause disturbances in the human body if normal levels are not maintained.
Carbon dioxide is an atmospheric constituent that plays several vital roles in the environment. It is a greenhouse gas that traps infrared radiation heat in the atmosphere. It plays a crucial role in the weathering of rocks. It is the carbon source for plants.

Answer:
huh ? what are yu asking ?
Explanation:
A researcher is studying a cornfield that has been recently abandoned by a farmer. By the end of one year, wild grasses begin to grow in the field. Explain whether this is an example of primary succession or secondary succession. Describe how the researcher can identify when a climax community is reached in the area that was a cornfield.
It is an example of secondary succession.
The community is considered a climax community once it has reached equilibrium, and the environmental conditions and species composition do not change very much.What is succession?Ecological succession is the process by which the mix of species and habitat in an area changes over time. Gradually, these communities replace one another until a climax community is reached.Example -A dirt field is plowed and left over the summer.-Over the summer, weeds start to grow on the field.
- After the weeds grow, small shrubs begin to take root.
- After a few years, trees begin to grow in the field.
