The Deoxy Ribo nucleic acid (DNA) is a molecule which contains the instructions needed for an organism to develop, live and reproduce.
What is DNA Sequencing?The laboratory technique which is used to determine the order of the four bases which make up the DNA molecule is defined as the DNA sequencing. The genetic information that is carried in a particular DNA segment is given by DNA Sequencing.
A scientific instrument used to perform DNA sequencing is called the DNA sequencer. The order of the bases (Adenine), (Guanine), (Cytosine) and (Thymine) is determined by DNA sequencer.

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.

Answer:
Life is the condition that able an organism to grow, reproduce and perform other activities.
Explanation:
Life is the condition that differentiates living things such as animals and plants from non-living things, these conditions are the ability for growth, reproduction and other activities etc that can't be performed by non-living matter. The main difference between life and non-life or non-living matter is that life uses energy for physical growth and development while on the other hand, the non-living matter doesn't.
A species of organism has survived in a mild environment for thousands for years. Suddenly, the climate changes and the area becomes a cold and barren tundra. Which of the following traits might help the species survive?
A-short neck to help keep heat inside the body
B-thick fur to keep the organism warm
C-small size so the organism requires less food
D-all of the above
The trait that might help the species survive is ; ( B ) Thick fur to keep the organism warm
Tundras are barren land with harsh weather conditions such as extreme cold. and the most important factors any species that lives in a tundra is shelter and insulation.
For the species to survive in Tundra they need to keep warm because certain species can survive without food for long periods. To keep warm the species will have to develop a thick fur and a larger body size.
Hence we can conclude that the trait that might help the species survive is thick fur to keep the organism warm.

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.

Answer:
Environmental conditions
macroevolutionary
Explanation:
Environmental conditions has a great affect on the survival, growth and development of organisms. If the environmental conditions are suitable for the organism so it will increase in population while on the other hand, if the environmental conditions are against the organisms so the organisms extinct from that region. The emergence, growth, and extinction of a large class such as dinosaurs is an example of a macroevolutionary pattern. Macroevolution is defined as the evolution of groups larger than an individual species.

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.
