Answer:
If it is a gene mutation then it is during the S phase, and if it is a chromosome mutation, then during metaphase or anaphase.
Explanation:
Answer:
If there is no mitosis there would be no cell growth and ce!l reproduction most of the importantly genetic information cannot be passed on and then therefore all the cell functions would be hugely affected.

Sand has the smallest particle size and clay has the biggest particle size while silt is in between the two. The correct order will be clay – silt – sand.
What are the generations which has been used in the cross?The first generation crossed which included the true breeding parents are the P generation plant. This produces the two subsequent generations which are the first filial generation (F1) and the second filial generation (F2).
In his breeding experiments, mendel first crossed true-breeding plants to produce a second generation, which were then allowed to self-pollinate to generate the offspring. Gregor Mendel performed series of experiments with pea plant to determine the law that governs inheritance.
In the parental generation (P-generation), He crossed a truebreeding plant that is dominant for a particular trait i.e. a plant that contains the same dominant alleles in its genotype and a truebreeding plant that is recessive for a particular trait i.e. contains same recessive alleles for the same gene.
Therefore, Sand has the smallest particle size and clay has the biggest particle size while silt is in between the two. The correct order will be clay – silt – sand.

how do you think the study of heredity may help the human race in the future
This helps determine which traits are passed down from parent to child. Successful traits are more frequently inherited and change species over time.
What is heredity?Heredity refers to the specific mechanisms by which characteristics or traits are passed down through generations via genes. Genes contain the instructions for producing specific proteins.
Normally, heredity is defined as the process by which an offspring inherits predisposed characteristics from its parent cell.
It is the process of passing down genetic traits from parents to offspring, which is initiated by recombination and gene segregation during cell division and fertilization.
Understanding genetic factors and genetic disorders is essential for learning more about health promotion and disease prevention.
Some genetic changes have been linked to an increased risk of having a child with a birth defect or developmental disability, as well as developing diseases like cancer or heart disease.
Thus, this way, the study of heredity may help the human race in the future.

remove dirts using hard cloth
Answer:
It can easily remove dirt.
Explanation:
When dirt is present on the hard surface such as car or machines so it can be cleaned by using hard cloth because the dirt attached tightly to the surface which can only be removed from that surface with the help of using hard cloth. Hard cloth has rough surface which easily remove the dirt from the surface as compared to the light cloth so that's why hard cloth is used to remove dirt from the surface.

Which group has the smallest dispersal distances
a) Seaweeds
b) Fish
c) Crabs
d) Marine Snails
Answer:
d) Marine Snails
Explanation:
Marine Snails has the smallest dispersal distance because of their slow mobility and stick to one place. These marine snails have very limited mobility when they are adults and spend their majority of lifetimes in a small geographical area. Dispersal distance refers to the distance a species can move from an existing place or population or the parent organism. According to this definition we can say that marine snails have the smallest dispersal distances.

7. Slime molds are fungus like protists, but they are not fungi. Why?
Answer:
Because they can move
Explanation:
Fungi cannot make food themselves so they depend heavily on hosts. Also fungi lack the proper cilia to move, so they use spores instead to "move".
In the case of slime mold, they are like an animal fungus per se. They are like Protozoa in their amoeboid plasmodial stage and similar to true fungi in spore formation.

The purpose of mitosis is to create two new perfectly identical cells when either there is a need to replace old or damaged cells and to reproduce asexually by making new cells. Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring.
There are four stages of mitosis: prophase, metaphase, anaphase and telophase.
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres
2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)
3) Anaphase: sister chromatids are pulled to opposite poles of the cell
4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin
● The order of the stages of mitosis can be remembered using the mnemonic PMAT.

Make a diagram of the reproductive cycle of a virus and discuss this form of reproduction with the pandemic situation we are experiencing today.
Answer:
There are six basic stages in their life cycle:
Attachment is a specific binding between viral capsid proteins and specific receptors on the host cellular surface. This specificity determines the host range and type of host cell of a virus. In the case of coronavirus, the spike proteins bind to ACE receptors on lung cells. Attachment to the receptor induces the viral envelope protein to undergo changes that result in the fusion of viral and cellular membranesPenetration through receptor-mediated endocytosis or membrane fusionUncoating, a process in which the viral capsid is removedReplication of viruses involves primarily multiplication of the genome. Replication involves synthesis of viral messenger RNA (mRNA) from "early" genes, viral protein synthesis, possible assembly of viral proteins, then viral genome replication mediated by early or regulatory protein expression.

events that damage the cell’s regulatory apparatus can cause the uncontrolled division of cells called
Answer:
??????????????
Explanation:
In cancer, uncontrollable cell division occurs because when cells within an organism begin to divide and damage the cell’s regulatory apparatus there is no way to stop this process.
What is cancer?Every cell in the body has a certain lifespan, and at some point during that lifespan, the cell receives instructions to stop dividing and replicating.
But when a cell gets cancer, this regulatory system fails, and the cell enters a phase of uncontrolled cell division. Diseases like cancer can develop when the cell cycle's regular control is disrupted.
When the cell cycle is unchecked, cells can divide randomly and amass genetic flaws that can result in a malignant tumor.
Therefore, damage to the cell’s regulatory apparatus can cause the uncontrolled division of cells called cancer.
