Plant cells are different from animal cells because they are usually

Answers

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. Animal cells simply have a cell membrane, but no cell wall.

An investigator wishes to use animals in an experiment that involves category B, C, and D activities performed on the same animal. How should the animal be categorized

Answers

Answer:

Category D

Explanation:

In the USA, the Federal Animal Welfare Regulations require that research laboratories report animal use according to the species as well as the number of individuals subject to experimentation procedures. Moreover, animal use for research/teaching purposes is also reported according to the classification by pain and distress categories. Basically, this classification has four categories (B,C, D and E) in increasing order according to the pain level suffered by research animals. Animals within Category D include those subjected to potentially painful or stressful procedures. In consequence, in this category, it is imperative the utilization of proper anesthetics and/or analgesics in order to diminish the pain and suffering of these animals at the lower level possible.

A species of elm has winged-seeds. How would biologists explain how a species of elm with winged-seeds evolved from an ancestral elm species without winged-seeds

Answers

Answer:

In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species

Explanation:

A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.


6. In general, as both the force and velocity of impact increase, what happens to the diameter of
the resulting blood droplets?

Answers

Answer: depending on viscosity, mass and velocity of impact, if droplet integrity is maintained, as velocity increases, diameter will increase from

Approximately d*sqrt(2) to 2*sqrt(d^3/6a) where d is original diameter and a is thickness when the droplet flattens into a disc.

Explanation:

This applies generally to any liquid droplet, which by inference falls and impacts a solid surface. The impact force is mgh where m= mass, g= acceleration due to gravity, h= initial height.

A liquid droplet deforms on impact. Assume the drop is sperical, then the deformation distance, d= diameter of the droplet then the average impact force = mgh/d.

The droplet may spread, splash or bounce, depending on viscosity and force, which depends on mass and velocity immediately before impact.

All than can be said is that if the droplet maintains integrity it could achieve the shape of half a highly flattened oblate spheroid. Approximating this with a flattened disc of thickness a, and an original volume of 4/3pi(d/2)^3, the volume as a disc =a*pi*r^2 so the horizontal diameter = 2*sqrt(d^3/6a)

It is not really possible from the available data to determine whether the droplet would remain its integrity, but at sufficiently low force/velocity, the droplet could retain a near-hemispherical shape, giving a horizontal diameter of the hemisphere = d*sqrt(2)

As velocity increases, if integrity is maintained, the diameter will increase from the second approximation to the first

Difference: Conductors are materials that permit electrons to flow freely from particle to particle. Conductors allow for charge transfer through the free movement of electrons. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule.

Similarities: Both conductors and insulators deal with the electric conductivity of a surface or material. Everything is either a conductor or an insulator. It is a conductor if it readily allows electrons to flow across it, when there is a potential voltage differential between two points on the surface.

- the amount of iron in blood depends on the amount of red meat a person eats.

Answers

Answer:

The answer is:

Independent: red meat eaten by a person

Dependent: iron in the blood

Explanation:

A dependent variable has to depend on something else, so in order for a dependent variable to exist or happen, there has to be the independent variable. The independent variable is something that does not need anything else to happen for it to take place. It s independent. Such as, a mother cannot have a child without sperm. The mother have a child is dependent, where the sperm is independent.


What are the functions of proteins in cells and viruses?​

Answers

A viral protein is both a component and a product of a virus. Viral proteins are grouped according to their functions, and groups of viral proteins include structural proteins, nonstructural proteins, regulatory proteins, and accessory proteins.[1] Viruses are non-living and do not have the means to reproduce on their own, instead depending on their host cell's resources in order to reproduce. Thus, viruses do not code for many of their own viral proteins, and instead use the host cell's machinery to produce the viral proteins they require for replication

The house fly, Musca domestica, has a haploid chromosome number of 6. How many chromatids should be present in a diploid, metaphase cell (metaphase of mitosis)

Answers

Answer is 24
Question: The House Fly, Musca Domestica, Has A Haploid Chromosome Number Of 6. How Many Chromatids Should Be Present In A Diploid, Somatic, Metaphase Cell? The Answer Is 24.

24 chromatids should be present in a diploid, metaphase cell (metaphase of mitosis).

What is mitosis?

Chromosome replication and equitable distribution between the two daughter cells occur during the cell division process known as mitosis. Each daughter cell has the same number of chromosomes as the parent cell, making them diploid. Hence, mitosis is sometimes referred to as equational division.

There are four phases in mitosis and that is prophase, metaphase, anaphase, and telophase.

Thus, If the house fly has a haploid chromosome number of 6, which means it has 12 chromosomes in a diploid state. When a cell undergoes mitosis, the diploid chromosome number of the cell becomes double. Therefore, there will be 24 chromatids in a diploid metaphase cell.

A scientist is using a microscope to observe a type of
bacteria.

Which two structures would the scientist most likely see?PLEASE EXPLAIN WHY

A:nucleus and DNA
B:DNA and cell wall
C:cell wall and vacuole
D:vacuole and nucleus

Answers

Answer:

The two structures most likely to be observed by the scientist when looking at a type of bacteria under the microscope are cell wall and vacuole (option C).

Explanation:

Bacteria are prokaryotic organisms that lack a nucleus, most of the organelles, and whose DNA is dispersed in the cytoplasm. Some types of bacteria have a plasma membrane surrounded by a cell wall, and may be equipped with vacuoles to perform their functions.

It is very likely that two structures that are most likely to be differentiated when a type of bacteria is observed under the microscope are the cell wall and the vacuole, according with information above.

The other options are not correct because:

    A and D. Bacteria lack a nucleus.

    A and B. Bacterial DNA is dispersed in the cytoplasm and is very difficult to observe under the microscope.
