If the surface of a bacteria cell was not very antigenic then it can enter host cells and eventually cause harm.

An antigen is any molecular structure present in a pathogenic organism (e.g., bacteria) that can be detected by the immune system.

Antigens usually bind to antibodies that are able to bind specific antigenic features and thus trigger a concomitant immune response.

In conclusion, if a bacteria cell was not very antigenic then it can cause harm.

Your teacher will probably go over the lab procedures with you and your classmates before you lead an experiment.

You will often receive a printed guide that describes the experiment in depth in addition to verbal instructions, frequently with pictures and drawings.

It's important to pay attention as your teacher goes over the directions so you can complete the experiment correctly and securely when class starts.

Be careful when handling chemicals, reagents, and stains, and heed all instructions. The contents and any potential hazards are listed on the labels of all bottles and containers. Avoid contact with the chemical and fumes, for instance, if the label instructs you to.

Your teacher will probably go over the lab procedures with you and your classmates before you lead an experiment.

You can keep yourself safe in the lab with the appropriate clothing and tools. Depending on the experiment, your teacher should provide you with particular directions on what to wear to each class as each one calls for the use of various tools and substances that have varying degrees of hazard.

Though they are not something you should be preoccupied by, as mentioned above, accidents in school laboratories are rather common. Your teacher should review with you what safety equipment your lab contains.

Explanation:

During prophase, the chromosomes condense and centrosomes move to opposite sides of the nucleus, initiating formation of the mitotic spindle.

The lysogenic cycle involves the spread of viral DNA when prokaryotic microorganisms reproduce and the lytic cycle destroys the host cell immediately.

The lytic cycle is a type of reproductive cycle in viruses that involve the destruction of the host cells.

Conversely, the lysogenic cycle occurs only in prokaryotic cells and it does not involve the destruction of these cells.

In conclusion, the lysogenic cycle uses prokaryotic reproduction and the lytic cycle destroys the host cell.

The diameter of the high power field in micrometers is 9600 micrometer (9.6 mm).

[tex]\frac{200}{1600} =\frac{1,2}{x}[/tex] = 9,6 mm

Compound microscope lenses are called objective lens and ocular lens. The objective lens is a lens that is installed very close to the object being observed. The ocular lens is very close to the observer's eye.

With this information, we can conclude that the high power field in micrometers is 9600 micrometer (9.6 mm).

Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.

prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)

metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.

anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.

telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.

interphase This is a resting period.

A- dwarf planets orbit the sun

Dwarf planets orbit other planets. Therefore, option (C) is correct.

The primary distinction between moons and dwarf planets lies in their respective orbits. Moons are natural satellites that encircle planets, whereas dwarf planets directly orbit the Sun. Moons are celestial entities that revolve around larger planets, functioning as their satellites. A notable illustration is the Earth's moon, which is a natural satellite revolving around the Earth.

Conversely, dwarf planets are celestial bodies that orbit the Sun but have not successfully eliminated other debris from their orbital paths, in contrast to fully recognised planets. Pluto serves as a prominent example of a dwarf planet within our solar system. While it orbits the Sun akin to a planet, it also shares its orbit with other objects situated in the Kuiper Belt. Therefore, option (C) is correct.

Answer:

Explanation:

mainly because the more people that build homes in the areas where the aniamls lives the more trees gets cut down leaving the animals with no homes so the leave.

The correct answer is (A). Deforestation.

Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests.

Moreover, deforestation is the purposeful clearing of forested land. Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction. Deforestation has greatly altered landscapes around the world.

Hence, the loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for Indigenous people.

Acacias communicate with each other in response to insect attack by producing a gas called ethylene.

When antelopes begin to eat the leaves of an acacia tree, the tree emits a signal of ethylene gas into the air through the pores of its leaves. This signal can travel up to 45 meters warning other nearby trees of the presence of herbivores. Once the signal is received, acacias begin to produce tannin in their leaves in amounts that are lethal to antelopes.

With this information, we can conclude that Acacia trees, when eaten by grazing giraffes, release ethylene gas, which prompts other acacias to flood their leaves with bitter tannins.

As the male is long-haired with a black coat means genotype Bbss and the female is having short hair and black coat means genotype BbSs. The offspring genotype can be BBSs, BBSs, BbSs, and bbss.

In a broad sense, the term "genotype" refers to an organism's genetic makeup; in other words, it describes an organism's entire set of genes. In a narrower sense, the term can refer to the alleles, or variant forms of a gene, that an organism carries.

Black hair in rabbits is determined by a dominant allele, B, and brown hair by a recessive allele, b. Short hair is caused by a dominant allele, S, whereas long hair is caused by a recessive allele, s.

The Punnett square for the given scenario can be shown in the image attached below:
