Answer:
Stem cells cut and repair their own DNA to promote formation of new tissues.
Explanation:
Stem cells cut itself and then repair their own DNA as a mechanism of activating genes that promote the development of new tissues. Stem cells are special type of cells that the ability to develop into many different types of cell such as muscle cells, brain cells etc. These cells are also capable to repair damaged tissues in the body.
In 1898 Friedrich Loeffler and Paul Frosch found evidence that the cause of the highly contagious hoof-and-mouth disease in livestock was a microscopic infectious particle. It was discovered that this particle requires a host cell to reproduce. Which pathogen is most likely responsible for causing hoof-and-mouth disease in livestock?
Answer:
Enteroviruses.
Explanation:
Enteroviruses is the pathogen that is responsible for causing hoof-and-mouth disease in livestock. Infection of this virus causes a vesicular eruption on the hands, feet, and oral mucosa in the livestock animals which greatly damaged the health of animals. These viruses needs a host cell to reproduce because it is a virus which is non-living outside the living cell.

Why do cells need to replicate their DNA?
Answer:
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
Explanation:
DNA is the genetic material, which is found in every living cell. The DNA is made up of a pentose sugar, nitrogenous base, and phosphate backbone.
DNA is a genetic material that transmits the information from parent cell to daughter cell using DNA replication.
DNA replication is an essential process in which the daughter cells inherit information from the parent cell.
Cell division is a process through which a DNA copies its genetic material and delivers it to the newly forming daughter cells.
The genetic information in the daughter cell must contain the same set of rules and instructions to carry out the vital processes. The information is present in the original copied form of DNA from the parent.
Thus, DNA replication is necessary for the continuity of life and similar genetic information presents the daughter cells.

The allele for a sixth finger is dominant and the allele for a non-sixth finger is recessive. In the human population the percentage of people with the dominant phenotype is LESS than the percentage of people with the recessive phenotype. How could you explain this?
Answer:
Explanation:
Polydactyly is having six fingers as against the 5 fingers. The Sixth fingers grows out like normal finger giving an additional finger.
Polydactyly is usually expressed in dominant form, when an individual is recessive for the traits such individual have 5 fingers.
In human, the rate of occurrence for polydactyly is low this is because it is a rare occurrence and it takes two individual who have the allele to produce an individual who will be dominant of the allele. The recessive allele is what is common to human.

how is the ruminant digestive system different than human digestive system?
background info:
Digestive system in animals is an important system in the context of digestion of ingested food into simpler forms that could be easily absorbed by the body cells.
This provides all the essential compounds needed by the body for the existence and development of the living organism. Different digestive systems have evolved according to different species, their feeding patterns, and their habitats.
answer:
Ruminant species survive only on plant matter. They are herbivorous animals.
Therefore, the digestive system of ruminants is evolved with the presence of a rumen which is a complex stomach with four different compartments.
Humans are omnivorous who depend on plant and animal matter both thus, their digestive system composes of one stomach.
This is the key difference between digestion of humans and ruminants.
hope this helped
Answer:The primary difference is that ruminants have modified their stomach into multiple compartments in order to host a very vibrant and diverse community of microorganisms. Some of these microorganisms are able to digest cellulose and produce volatile fatty acids. These volatile fatty acids are used as a source of energy by the ruminant. Propionate - a volatile fatty acid, is the only volatile fatty acid used for gluconeogenesis.
The rumimal microbe community also provides other nutrients as well but is mostly known for its role in cellulose digestion.
Ruminants have also evolved the ability to bring up a small ball of feed from their rumen to their mouth. They then masticate (chew) this ball to breakdown the fibrous material. This ability is commonly referred to as “chewing their cud” or ruminating. hope this helps have a bless day❤️❤️

Originally the Continental Drift Theory was not well received by other scientists. Why?
A. There was a competing theory at the time which was more believable.
B. There was no data showing the continents ever moved.
C. The scientists didn’t know the force responsible for moving the continents.
D. The scientist presenting the data was unreliable.
Answer:
C
Explanation:
The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.

Divergent boundary is the type of boundary or zone depicted in the image.
What is divergent boundary?In plate tectonics, a diverging boundary, also known as a divergent plate boundary, is a linear structure that exists between two moving tectonic plates.Rifts are formed by divergent boundaries within continents and develop into rift valleys over time.A diverging border is formed when two tectonic plates diverge.Earthquakes frequently occur along these boundaries as magma (molten rock) rises from the Earth's mantle to the surface and solidifies to form new oceanic crust. Divergent is the movement of two plates away from each other. Molten mantle rock erupts along the opening, forming new crust. The earthquakes that occur along these zones, known as spreading centers, are small.To learn more about divergent boundary, refer to:

Due to climate change, places that used to be colder are now warming up, allowing new invasive species to establish themselves. What is one way that warming conditions are beneficial to invasive species?(1 point)
Warm weather allows animals to travel farther and longer because they do not need to hibernate for winter.
Warming leads to longer life spans for the animals because none die due to exposure to the cold.
There is more food and shelter available since the growing season is year round.
If the location used to be too cold for non-native species, it is now warm enough to allow them to exist.
(Q1)An introduced species is not necessarily harmful to the environment; an invasive species has a negative effect.
(Q2) the number of species in a community
(Q3) If the location used to be too cold for non-native species, it is now warm enough to allow them to exist.
(Q4) It reduces biodiversity by reducing successful mating in native species.
(Q5) Large because it has led to several significant changes, including new invasive species and loss of natives.
Explanation:
i just did the quick check
Warming conditions are beneficial to invasive species because if the location used to be too cold for non-native species, it is now warm enough to allow them to exist. Option D is correct.
What are invasive species?When species move and establish in a new area, out of their original distribution range, they might be considered exotic or invasive, according to their
• reproductive rate,
• population growth, and
• interaction with native species.
When a new species stablishes and overgrow in a new area, negatively affecting native ecosystems dinamics, they are considered invasive species.
The introduction of invasive species has ecological, economic, socio-cultural consequences.
In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-.
These factors favor their establishment because they are adapted to surviving under harder conditions.
They interact with native species by
Competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-.Predating on native species, consuming a wide diversity of prey items, and in many cases, there are no native species that may prey on them.They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species.
They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.
Areas that get warmer due to climate change provide a propicious environment for invasive species to stablish and overgrow.
Temperature is not a limmiting factor any more for these species, so they can move and stablish in these areas.
Warming conditions are beneficial to invasive species because if the location used to be too cold for non-native species, it is now warm enough to allow them to exist.
Option D is correct.

the chromosome is true?*
chromosome
A. Each half of the chromosome is genetically identical.
B. Once formed, a chromosome always stays in this X shape.
C Each half of the chromosome contains genetically different material
D. The pinched middle of the chromosome is what allows it to split during mitosis.
Answer:
A. Each half of the chromosome is genetically identical.
Answer:
C
Explanation:
I would say it is C.
Each cell has 23 chromosome (46 in total). 23 is from our mother, 23 from our father. So this would mean the chromosomes are not genetically identical, hence we have variation.
