Why is animal testing bad?
Answer:
Explanation:
Animal experiments may result in clinical trials of biologically faulty or even harmful substances, thereby exposing patients to unnecessary risk and wasting scarce research resources. Animal toxicity studies are poor predictors of toxic effects of drugs in humans.
Answer:
Experimenting with animals is not justified with anything, they practically play with beings that have life, emotions and that feel pain like all living beings.
Advances the experiments that are done on them, are not used, or the purpose is simply lost, as well as their life.

The bud shown in the diagram below was produced by asexual reproduction. Which process is responsible for the formation of the bud?
2 Asexual reproduction differs from sexual reproduction in that, in asexual reproduction..
(a) new organisms are usually genetically identical to the parent
(b) the reproductive cycle involves the production of games
(c) nuclei of sex cells fuse to form a zygote
(d) offspring show much genetic variation
Answer: 1. Mitosis
2. Answer A.
Explanation:
Stick insects that reproduce asexually are less biologically diverse because they can't evolve as quickly as species that reproduce sexually can. Thus, option A is correct.
What is role of asexual reproduction in evolution?Asexual reproduction, in contrast to sexual reproduction, only contributes to genetic variety in the population if a chance mutation in the organism's DNA is passed on to the progeny.
Evolution can occur gradually. Asexual creatures often evolve relatively quickly following a dramatic mutation and do not need as many generations to accumulate adaptations as do populations that reproduce sexually.
Asexual reproduction has the benefit of allowing for rapid population growth under the right circumstances. You only require one parent. Since you don't require a partner, it is more time and energy efficient.
Therefore, new organisms are usually genetically identical to the parent.

Calculate the number of liters of liquid that are in Lake Erie, which has a volume of 484 cubic km (km3). Express your answer in scientific notation.
Answer: The answer in scientific notation is [tex]4.84\times 10^{14}[/tex]
Explanation:
The conversion factor is : [tex]1km^3=10^{12}L[/tex]
Given : Volume of liquid in Lake Erie = [tex]484km^3[/tex]
To find : Volume of liquid in Lake Erie in units of liters
As [tex]1km^3=10^{12}L[/tex]
Thus [tex]484km^3=\frac{10^{12}}{1}\times 484=484\times 10^{12}L[/tex]

3. Which feature is commonly formed
at a plate boundary where oceanic
crust converges with continental crust?
(1) a mid ocean ridge (2) an ocean trench (3) a transform fault (4) new oceanic crust
Answer:
2) an ocean trench
Explanation:
Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.
What is Ocean Trench?Long, narrow depressions on the seafloor are known as ocean trenches. These chasms are among the deepest natural places on Earth and the deepest portions of the ocean.
Every ocean basin on the planet has ocean trenches, but the deepest ones encircle the Pacific Ocean as part of the so-called "Ring of Fire," which is also home to active volcanoes and earthquake-prone regions. Tectonic activity, which refers to the movement of the Earth's lithosphere, is what causes ocean trenches.
Ocean trenches in particular are a characteristic of convergent plate borders, which occur where two or more tectonic plates collide. In a process known as subduction, dense lithosphere melts or slides beneath less dense lithosphere along numerous convergent plate borders, forming a trench.
Therefore, Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.

Explanation:
If a SARS-CoV2 virus were to mutate and become and become better at attaching to respiratory cells, how would natural selection lead to this mutant virus becoming the dominant virus type? Use the four steps of natural selection in your response: overpopulation, genetic variation, competition, differential reproductio.
Answer:
Mutations leading to the better attachement of virus to the host cell would allow the virus to spread the infection and leave more progeny. The reproductive fitness of mutant viruses would allow the mutation to spread.
Explanation:
1. The organisms with same resource requirement compete with each other. Viruses are not living things but once inside the host cell, they behave like living things. Rapid multiplication of virus overpopulate the host cells.
2. Genetic variations are added to the viral progeny by random errors during replication of the viral genome. These random variations may impart beneficial trait, harmful feature or remain neutral. If a random mutation in the SARS-CoV2 virus allows it to adhere better to the cells of the respiratory system, the virus would be better able to infect these cells to spread the infection. Once inside the host cells, the mutant virus would leave more progeny. On the other hand, the wild type virus that lack this mutation would have lesser chances of entering the host cells and may or may not replicate.
3. The progeny of the mutant virus would compete better with the non mutant ones due to the presence of same mutation.
4. Differential reproduction and more progeny of the mutant virus would spread the mutation among the virus.

Answer:
Example of potential energy being transformed into kinetic energy will be; Holding a ball in your hands and then throwing it down a hill. The move of the ball as being transformed to kinetic energy.
Explanation:
Potential and kinetic energy are two forms of energy that can be converted into each other. Potential energy is the energy held by an object because of its position relative to other objects or its electric charge. While kinetic energy of an object is the energy that it possesses due to its motion.

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).
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 ...

What are the differences between white blood cells and normal eukaryotic cells?
Answer:
White blood cells (WBCs) are specialized to respond to antigen and produce antibodies as well as undergo phagocytosis in response to toxic stimuli.
WBCs are part of immune system and there are five different kinds with specialized features.
In order to make a cell model, it is best to use a muscle cell and a nerve cell or neuron: there are pronounced structural differences and those are present throughout animal kingdom.
Lower animals ( such as insects, worms etc. ) have different immune system, however, they do have typical neuron and a muscle cell/skin cell (fibroblast). Such cell models are likely to be easy, distinct and bring you good grades without going through much complication and confusions of various organ systems and animal mod
Explanation:
The infection-fighting cells that are produced by the immune system are manufactured in specific places around the body, for example, in the lymph nodes and the spleen. However, an infection can occur anywhere in the body. How do these infection-fighting cells manage to move around the body and get to the sites of infection?
A. There are lymph nodes every few millimeters all over the body.
B. They are excreted and float freely around the body, hunting infections.
C. They are carried around the body in the circulatory system.
D. They are moved around the body as muscles squeeze against them.
