What does the Teacher's Pet Video: Mitosis and Meiosis give as the main reason for the
production of haploid cells during meiosis?
because both the parents' and offspring's diploid cells will then be genetically identical to one
O because the two haploid cells will fuse together to make a new genetically different diploid cell
that will form the offspring
O because the sperm brings all of the father's genes to the egg allowing for the baby to have a
different number of chromosomes
O because the egg and the sperm will then be able to each form a new diploid offspring through the
process of meiosis
Answer:
The main reason for the production of haploid cells during meiosis is because the two haploid cells will fuse together to make a new genetically different diploid cell that will form the offspring.
Explanation:
In the context of sexual reproduction, meiosis is the process of cell division by which gametogenesis occurs. In this process, diploid cells are used to obtain haploid cells, called gametes.
The reduction of the chromosomal charge that occurs in meiosis is aimed at producing haploid cells —with half of the crosmosomes of a species— so that when the parents' gametes join, they form a diploide cell called zygote.
The zygote is the starting point for the development of a new individual, part of the offspring.

Which end of the pH scale contains solutions what’s the most hydrogen ions
Answer:
Acid end
Explanation:
The acid end of the pH scale contains solutions that have the most hydrogen ions.
A convenient scale for expressing the level of acidity or alkalinity of aqueous solutions is the pH or pOH scale . The pH of a solution is the negative logarithm to base 10 of the hydrogen ion concentration in the solution. The scale ranges from 1 to 141 is the lower limit and 14, the upper limitAcidic solution has a pH value less than 7. As pH decreases the hydrogen ions concentration increases. Neutral solutions have pH of 7 Basic solutions have pH greater than 7.HELP QUICK PLEASE!!

what is mitotic metaphase?
Answer:
Metaphase is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage. These chromosomes, carrying genetic information, align in the equator of the cell before being separated into each of the two daughter cells.

. Which waves cause the most movement of the rocks during an earthquake?
A. surface waves
B. S-waves
C. P-waves
Answer:
A
Explanation:
There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.

Compare and contrast the two types of bonds
Answer:
An ionic bond is formed between a metal and a non-metal. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
Explanation:
There are two types of atomic bonds - ionic bonds and covalent bonds. They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.
external signal that controls the cell cycle
Answer:
External factors include physical and chemical signals. Growth factors are proteins that stimulate cell division. – Most mammal cells form a single layer in a culture dish and stop dividing once they touch other cells.

Which of the following is one of the ways that cellular respiration and photosynthesis are opposite processes?
A.)Photosynthesis releases energy, and cellular respiration stores energy
B.)Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.
c.)Photosynthesis removes oxygen from the atmosphere, and cellular respiration puts it back,
d.) Photosynthesis consumes glucose, and cellular respiration produces glucose.
Answer:
B.)Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.
Explanation:
One of the ways in which photosynthesis differs from respiration is that photosynthesis removes carbon dioxide from the atmosphere and cellular respiration puts it back.
Photosynthesis is the process whereby green plants manufacture their food in the presence of sunlight using carbon dioxide and water. The product is usually glucose and oxygen. Respiration breaks down energy rich compounds into ATP, carbon dioxide and water.are replicated so there are
sets in the cell.
Answer:
meisosis I don't rember how to spell it lol. But I believe that it is the answer

How are food webs different to food chains? Explain why foodwebs are more useful
Answer:
Explanation:
A food chain is different because it shows what organisms eat in a straight line, in a chain. For example, a bird of prey can eat a snake that previously had eaten a frog and the frog ate a grasshopper and so on. But this tells us very little. A foodweb will tell us how all those animals are connected and what they eat in a web, not just a line.
why does the respiratory system require two organ systems
Answer:
The lungs expel the carbon dioxide and bring in new oxygen-containing air. Only when both systems are working together can oxygen and carbon dioxide be successfully exchanged between cells and environment. There are many other examples of this cooperation in your body. :)
I hope this was the answer :3

I said what I said
Answer: muscles and ligaments
Explanation:
What type of contraction, concentric or eccentric, would cause more fatigue to occur in a muscle? Why?
Answer:
concentric
Explanation:
Eccentric contractions are lengthening movements of your muscles. During this muscle movement, your muscle fibers are stretched under tension from a force greater than the muscle generates. Unlike a concentric contraction, eccentric movements do not pull a joint in the direction of a muscle contraction.
Answer:
Eccentric contractions have recently shown to be caused greater low- frequency fatigue than concentric. This is because size of fall in the force from eccentric contractions carry out on fresh muscle is signifgantly larger. Explanation:
