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.

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.

what does DNA need to replicate
In order to replicate, DNA needs the help of a lot of enzymes and primers (helicase, DNA polymerase, RNA primer, ligase, etc) It is also SUPER important that there is a template for the DNA to replicate off of so that the genetic info is passed on from one generation to the next without any changes or damage to the DNA

Answer:
No
Explanation:
Emest Rutherford's atomic model included a nucleus comprised of positive particles called protons. Later, James Chadwick discovered neutrons. How did
Chadwick's discovery change the atomic model?
A The new model showed a negatively charged nucleus.
B. The new model showed a neutrally charged nucleus
C. The new model showed a larger electron cloud.
D. The new model showed a nucleus with two types of particles
Answer:
D
Explanation:
It can't be A as nuclei must be positive.
It can't be B as nuclei must contain at least one proton, and no electrons.
Technically C may be true, but the question is asking about the nucleus. Not the electron cloud. Electrons aren't found in the nucleus. Only protons and neutrons.
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.

What is Base pairing?A base pair is defined as the basic unit of a double-stranded nucleic acid, consisting of two nucleobases bound to each other by hydrogen bonds, where they form the building blocks of the DNA double helix and the folding of both DNA and RNA contribute to the structure.
The rules of base pairing are:
A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T), bond with double bondC with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G), bond with triple bond.The base pair also depend on the size of each organism.
Thus, the presence of each base is dependent on the size of the organism. So, the correct option is D.

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.

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.
