If your cells couldn't go through meiosis- how could this affect you?
Answer:
An organism would not be able to reproduce without meiosis.
Explanation:
Between meiosis and mitosis, meiosis is by far not as important. If you are a asexual organism, this would be NOT IMPORTANT whatsoever. If you are a sexual organism, this would LARGLY effect you. But on a world scale, this is NOT AS IMPORTANT.
This is because, without mitosis, you could not heal and would die much much younger since your cells could not be replaced. On the other hand, without meiosis, any organism that reproduces sexually would be unable to do so, which could lead to extinction in many, many species. This would not be harmful, however, to species that can also or mainly reporuduce asexually through budding, fragmenting, or sporing. So overall:
Organisms that produce sexually would go extinct.
This is the only real affect I can think of. Since meiosis does not produce any cells aside from reproductive cells. And asexual organisms produce reproductive cells through other means.

Why do you think that some vaccines, such as the flu vaccine, need to be given every year?
Answer:
Because flu viruses evolve so quickly, last year's vaccine may not protect you from this year's viruses. New flu vaccines are released every year to keep up with rapidly adapting flu viruses.
Answer:
Because the virus/sickness would evolve and that vaccine might not protect you.

In at least 200 words explain how DNA replicates
Answer: Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.
~i hope this helps :)
Answer:
QUESTION:
ANSWER:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, like the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains
Meanwhile, as the helicase separates the strands, another enzyme called primase briefly attaches to each strand and assembles a foundation at which replication can begin. This foundation is a short stretch of nucleotides called a primer
After the primer is in place on a single, unwound polynucleotide strand, DNA polymerase wraps itself around that strand, and it attaches new nucleotides to the exposed nitrogenous bases. In this way, the polymerase assembles a new DNA strand on top of the existing one

¿Qué tipo de proceso metabólico se realiza cuando los lípidos y los fosfolípidos y triglicéridos se forman a ser moléculas sencillas dentro de la célula?
Answer:
catabólico
Explanation:
Los procesos metabólicos pueden ser:
Anabólicos: donde se forman moléculas más complejas a partir de moléculas simples. Esta formación de moléculas o estructuras más complejas consume energía. Catabólicos: donde se degradan o descomponen moléculas grandes o más complejas en otras más simples. Este proceso libera energía, que es utilizada en otros procesos y reacciones.En base a esto, la formación de moléculas sencillas a partir de moléculas grandes como los lípidos, fosfolípidos y triglicéridos es es proceso catabólico. En esta descomposición se produce energía para ser usada en otras reacciones.

How do large bodies of water affect the climate of a region?
Answer:
Large bodies of water, such as oceans, seas and large lakes, can affect the climate of an area. Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with a narrower temperature range.

Which plant structure absorbs most of the water and nutrients needed from the soil? tap roots secondary roots root hairs fibrous roots
Answer:
Root hairs
Explanation:
This is because the root hairs are part of root structure that are tubular and have lateral enlongations.
The root hairs increase the surface area of the root and allow for exchange.
They gave direct contact with the soil and then absorb water and nutrients to their increased surface area.

Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Which phase of the cell cycle is helicase most likely active?
A) S
B) М
C) G1
D) G
Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Helicase is more active in the S phase of the cycle. Option A is the correct answer.
What are the events of the cell cycle?
The cell cycle consists of the interphase and the cell division phase, where the cell division takes a little time in comparison to the interphase. The parent cell spends the majority of its time in the cell cycle's interphase and less time in the cell division phase.
There are three phases in the cell cycle's interphase: G1, S, and G2. The cell grows in both the G1 and G2 phases, while the DNA replicates in the S phase.
Hence, helicase is an enzyme that is responsible for unraveling the double helix of DNA by breaking apart the hydrogen bonds between each base pair. Helicase is more active in the S phase of the cell cycle. Option A is the correct answer.

Explanation:
Biodegradable products do not really present any problems because they can decompose on their own, thus they do not create any pollution. Aluminum is not as dangerous to the environment as plastics, for example.
Women gives birth to a baby boy. A few years later she gives birth to another baby boy. What is the probability that her third child will be a girl? Play your reasoning
Answer:
50 %
Explanation:
It is given that a woman gives birth to a baby boy. Her second child is also a baby boy. Now she is about to give birth to her third child. We have to determine the probability of the child to be a girl.
Here, the probability of the child to be a girl would be 50 % or 1 out of 2.
There are two possibilities and the possibilities would result a boy child or a girl child. So there are two possible outcomes and is equally likely with each child birth.
Also each child birth is an independent event, so the probability that the one results will occur do not depend on the previous births.

ANNOTATE Write the inputs and outputs of cellular respiration on this diagram.
Answer:
Inputs---- glucose and oxygen.
Outputs----- ATP, carbondioxide and water.
Explanation:
The inputs of cellular respiration are the glucose and oxygen whereas the outputs of cellular respiration are energy in the form of ATP, carbondioxide gas and water. cellular respiration is a process in which glucose is broken down in the presence of oxygen gas for the production of energy in the form of ATP molecules. Carbondioxide gas and water which are the waste materials also produced in the end of cellular respiration process. Cellular respiration is the reverse of photosynthesis.

View Available Hint(s) Why are liver extracts used in the Ames test? A liver extract is necessary for the bacteria to produce histidine revertants. Liver enzymes activate the bacterial enzymes. Liver enzymes may activate some innocuous compounds, making them mutagenic. The bacteria require the nutrients present in the liver extract for growth.
Answer:
Part A: False
Part B: Liver enzymes may activate some innocuous compounds, making them mutagenic
Explanation:
The Ames test, also known as Salmonella typhimurium reverse mutation assay, is a bacterial short-term technique used to identify if a particular chemical compound may cause mutations in target cells. It has been shown that there exists a positive correlation between carcinogenicity and mutagenicity in the Ames test, but this correlation is not absolute. In the Ames test, a rat liver homogenate (containing liver enzymes) can be added in order to identify substances that are not mutagenic themselves but are metabolized in order to form a mutagen (e.g., benzopyrene).

Consider the numbers of species known to exist on Earth, including the numbers that are being discovered and
the numbers thought to be going extinct. What do these
numbers suggest about biodiversity on Earth?
Answer:
A high diversity of species is known to exist among insects and land plants; fewer species are known to exist among vertebrates, bacteria, algae, arachnids, Protists, nematodes, mollusks and crustaceans. However, much greater diversity is estimated to exist among insects, fungi, bacteria, algae, and arachnids. Vertebrates are the best-studied organisms but are relatively less diverse than other groups.
