A. cells from a cell wall
B. cells undergo mitosis
C. cells increase in size
D. cells merge to become larger
Answer:
B. cells undergo mitosis

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.

Answer:
El cambio climático tiene un impacto negativo.
Explicación:
El impacto negativo en la biodiversidad del mosquito aedeomyia squamiennis se debe al cambio climático que disminuye su población porque el cambio climático hace que el medio ambiente sea desfavorable para el mosquito. Debido a este cambio climático, aquellos organismos que se adoptan de acuerdo con el cambio ambiental pueden sobrevivir pero aquellos que no pueden extinguirse del medio ambiente, por lo que podemos decir que el cambio climático tiene un efecto negativo en la biodiversidad del mosquito aedeomyia squamiennis.
What is the purpose of dermal or friction ridges? What does the imprint of a fingerprint consist of?
Answer: All fingers, toes, feet, and palms are covered in small ridges. These are raised portions of the skin, arranged in connected units called dermal, or friction, ridges. They help us with our grip on objects that we touch. When these ridges press against things, they leave a mark, an impression called a fingerprint.
Explanation:
Answer:
Their purpose on the body is to increase the surface area and increase friction so hands can firmly grasp things, and feet do not slip when walking.
The imprint of a fingerprint consists of natural secretions of the sweat glands that are present in the friction ridge of the skin
Explanation:
They help us with our grip on objects that we touch. When these ridges press against things, they leave a mark, an impression called a fingerprint.
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.

how homologous structures and vestigial structures are evidence of evolutionary relationships.
Answer:
Due to presence of these structures in ancient as well as modern organisms.
Explanation:
Homologous and vestigial structures are the evidences that show evolutionary relationships between organisms because these structure were also present in the ancient ancestor of that organism. These homologous and vestigial structures shows the relationship between the ancient and the modern organisms. Some structure has a purpose and function in the body of ancient organisms but with the passage of time those structure are useless and have no function in the body but these structure shows connection between modern and ancient organisms.

Which group has the smallest dispersal distances *
1 point
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. 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.

In trophic webs, any change affecting one of the links affects the superior and the immediately anterior link. Option b) decreased, increased, decreased.
What is a trophic web?
The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones. The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
• The first link corresponds to a producer organism -autotroph-.
• The following links are the consumers -heterotrophs-: herbivores and carnivores.
• The last links are the decomposers that degrade organic matter from dead organisms.
Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
To answer this question, we need to think about predatio-prey relationship.
In this food chain we know that
Urchins feed on kelp. Sea otters feed on urchins, and orcas feed on sea otters.So, the more orcas there are, the less sea otters there will be, because many orcas are feeding on them. Sea otters' population decreases in size.
↑ ocas ⇒ ↓ sea otters
Since there are fewer sea otters, the urchin population will be able to increase in size, because they are not affected by sea otter predation as they used to be.
↓ sea otter ⇒ ↑ urchins
Finally, the more urchins there are, the more affected kelp will be, because predation on them by urchins increases.
↑ urchins ⇒ ↓ kelp
The correct option is then option b. decreased, increased, decreased
↑ ocas ⇒ ↓ sea otters ⇒ ↑ urchins ⇒ ↓ kelp
decrease increase decrease

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 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.

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.

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.
